Show THE SALT LAKE TIMES FRIDAY, FEBRUARY 19, 1960 Page Three Chemical Corporation Proposes 'Bold Leap' to Win Space Race Bryce Wilhite, technical direc-tor for Thiokol Chemical Corp. Rocket Operations Center, Og-de- n, this week said that present technology makes it possible to design a solid propellant booster many times more powerful than the rocket engines now being used in our nation's interconti-nental ballistic missile program. This huge rocket booster could play an important part in our country's space program and be available within two to three years. Mr. Wilhite outlined different techniques that could be used to produce the large solid-propel-la- nt booster with enough thrust to lift heavy payloads ino orbit or to the moon. These include the segmented engine casting technique and on-sit- e loading. It has been reported that the present limitations imposed on the size and performance of rocket engines are associated with the problems of logistics. These logistic difficulties include building the large metal parts, constructing the required pro-cessing and launching facilities, and perhaps the most stressed and most important transporting the large engines from construc-tion plants to launch sites over already inadequate road sys-tems. Mr. Wilhite explained that these limitations were largely academic. "The segmented engine casting method for example, was proven feasible during the work accom-plished by Thiokol Chemical in 1952 on Loki missile propulsion system. The Loki propulsion" system was designed and de-veloped by the Jet Propulsion Laboratories and was built by Thiokol Chemical Corporation at its Redstone Division." The Loki engine was built in two segments, a cylindrical por-tion and a head end. These parts were assembled by fitting the cylindrical segment over the head end. Studies conducted in 1955 and 1956 proved that sev-eral cylindrical segments could just as easily be used to build larger engines. One method was used to prove that several cylindrical sections could be successfully attached to each other by . using "J" shaped expansion join seals, thus building one large engine. A second method was used to dem-onstrate that an engine case can be assembled from segments and loaded as a single engine. Both of these programs were conducted at Thiokol's Redstone Division. Both were successful. "In fact, an engine measuring approximately six feet in dia-meter was successfully case in a segment case and successfully static tested early in 1956." However, in commenting on the feasibility of this technique for engines over the two million pound thrust, Wilhite stated that the problems associated with handling each segment as a sep arate engine, as well as insulat-ing and protecting the joint sur-faces, seemed to indicate that on-si- te loading would be more fa-vorable. The on-sit- e loading technique requires the loading, curing and assembly of the solid propellant engine at the launching site, or close enough to this site so that the problem of transportation would no longer limit engine size. A paper on this process was presented by W. H. Haite, man-ager of process and development at Thiokol's Redstone Division at the American Society of Me-chanical Engineers meeting in March, 1959. Propellant for the large on-sit- e loaded engine would be mixed at a nearby processing plant or by a portable continuous mixer. Unique 'Farm' Raises Only Mice To Aid in the Study of Cancer shelves waiting to be tested, as-suring that the Wyckoff Colony will be operating for many years to come. The testing program has paid some dividends already. Within the past 12 years, Lederle has been able to make five useful cancer palliatives available to the nation's physicians. The Wyckoff colony has been run by Lederle sice 1948. It was established by Dr. Y. Subbarow, India-bor- n former former direc-tor of Lederle research, who rec-ognized the need for the stand-ardized animals as part of the organization's cancer screening efforts. The colony started with about 150 highly inbred mice from Dr. V. Bittner of the Uni-versity of Minnesota. The colony has been subsequently carefully inbred through 20 further gene-rations to preserve purity of the strain. They are now being used at the rate of 2,000 per week at Lederle's N. Y. Laboratory. The isolated colony of C3H mice is carefully tended by a crew of four men. The mice are housed in stainless steel boxes within an air conditioned build-ing that is frequently scrubbed down with a germicidal agent. Their diet consists of grain and commercial feed pellets supple-mented with auremycin. A couple of years ago the whole colony was almost completley decimated when contaminated feed threatened its continued existence. An emergency call to Dr. Rittner produced 19 nairs The chief crop of a farm in Wyckoff, N. J., is helping sci-entists in their efforts to solve the cancer riddle. The crop is mice. Wyckoff is the site of a mouse farm run by Lederle Laboratory Division, American Cyanimid Co. The farm supplies 100,000 special mice a year for use in Lederle's cancer research pro-gram. Tumors are implanted in each mouse and are later treated with chemicals to see whether . tumor growth can be halted or reversed. Although Lederle buys some 300,000 additional mice from outside sources each year for other research projects, only its home-grow- n variety is used in the cancer program. There are several reasons for this. One is that it's extremely difficult to implant a tumor into just any mouse and have it grow. Lederle highly imbred mouse strain, however, provides a good per-centage of "takes." Secondly, by using a highly standardized ani-mal the scientists are assured of more uniform and trust-worthy test results. Lederle's test procedure, which has been adopted by several cancer research groups, is a sta-tistically designed screening pro-gram which currently tests about 3,000 compounds anually for anti-canc- er activity. Since the program was initiated in 1945 more than 10,000 chemicals have been evaluated. But more than 30,000 remain on the Lederle of similarly bred mice to act as supplementary breeders. Lederle scientists were soon able to find the source of the contamination and shortly thereafter the colony was able to continue production. A unique aspect of the mouse colony is that many of the female mice develop spontaneous mam-mary cancers after a period of time. Thus the scientists have a research program under way to study the effect of various chem-icals on these tumors. Value Your Wife's Housekeeping At $5,800 a Year Why is it that wives are mak-ing increasing use of life insur-ance? One of the chief reasons, says the Institute of Life Insurance, is that homemakers are coming to recognize that the actual work they do in rearing their children and in maintaining a home counts as an economic contribu-tion to their families one that can be reckoned in dollars and cents and therefore protected by life insurance. When a father buys life insur-ance, his agent can analyze his family responsibilities in light of his earnings and savings, and thus be able to determine scope of a protection program for his family. But when it comes to a similar program for a mother, her "financial value" to her family could not be measured as precisely at least in the past. Recently, however, an expert in the area of family living has come up with figures that can help a family to see this prob-lem more clearly. Elliot Drisko of the Yonkers Family Service Society, has calculated how much a family in his locality would have to pay for house-keeping and other services, if the family consists of a widower and two children. Deciding that the family would need three em-ployees, one full time and two part time, he listed them as: 1. Combination nurse govern-ess at $80 a week. 2. Part time housekeeper for 16 hours a week, $1.50 an hour. 3. Baby sitter for six hours a week for 48 weeks a year at $1 an hour. Their combined salaries, to-gether with the Social Security taxes which the family would have to pay, come to more than $5,800 a year. Or, assuming that the young father would remain unmarried as long as five years as might be the case, the cost of household help overthis period would be nearly $30,000. Added to those would have to be the cost of Workmen's Com- - pensation insurance and liability insurance for the three em-ployie- es. And, Mr. Drisko said, further sums would be needed for advertisng, interviewing and screening and subsequent train-ing of a nurse governess by a child care agency, since the av-erage stay of a nurse governess is only three years. Even though both parents will probably live to see the children grown, and dandle their grand-children on their knees, it is obvious that many young fami-lies agree it is logical for the father and mother to carry life insurance protection. ; How can a mother use her life insurance in the later years? Judging by studies of life insur-ance statistics, many women use their life insurance to provide a legacy for their childern. If keeping up a policy in the re-tirement years is a problem be-cause of the drop in income this can be solved in one of two ways: by converting the insur-ance to a "paid up policy" in a smaller amount; or placing it on an "extended term" basis, for the same amount, with the life insurance protection applying for a specified number of years to come. Either way, premiums no longer have to be paid by the policyholder. On the other hand, many women who are able t o keep up their life insurance past re-tirement age do so, and look on the cash value of their policies as part of their savings a valu-able reserve in case that cash is needed in an emergency. Utah Farm People Plan S. L. Meetings Farm people of this area and every part of Utah and southern Idaho will take part in the 37th annual meeting of the Utah Poultry & Farmers Cooperative Saturday at the Hotel Utah in Salt Lake City. This cooperative is probably the largest farm co-o- p in Utah and one of the strong farm or-ganizations in th ecountry, made up of some 8000 farm families. The organization is owned and controlled by the members. D. O. Roberts of Henefer is now president and will preside at all meetings. He will make one of the main reports, along with H. M. Blackhurst, general manager, and C. K. Ferre, assistant. Meetings will start at 9:30 and continue through the day. The convention will be closed with a banquet and program, starting at 6:30 p.m. More than 60O are expected for the meetings. Officers for 1960 will be cho-sen along with three directors. Officers and directors of the organization, who will partici-pate in the annual meeting are: D. O. Roberts of Henefer, presi-dent; LeRoy R. Koyle of Span-ish Fork, first vice president; Theron M. Campbell of Provi-dence, second vice president; Vernon Jensen of Preston, third vice president; and theese direc-tors: J. Arza Adams of Pleasant Grove, Alton S. Gadd of Nephi, Kendrick Harward of Richfield, Carl F. Lundell of Payson, E. Smith Peterson of Salina, Wil-liam H. Schorr of West Jordan, Jesse W. Spafford of American Fork and Clyde C.

Welfare Payments A total of 11,977 persons, or approximately 3.18 per cent of the population in Salt Lake County received public assist-ance during June, 1959. State-wide, 3.15 per cent of the total population was on the public assistance rolls during the month. In June, 1950, 3.97 per cent of Salt Lake County's population was receiving public welfare, while in June, 1940, the percent-age was 7.67 per cent. The welfare roll trend in the state has been generally declin-ing during recent years. In the depths of the great depression (June, 1935) nearly 20 per cent of Utah's population received public assistance. These were some of the facts included in the 1960 edition of Statistical Abstract of Govern-ment in Utah, just published by Utah Foundation, the private governmental research agency. More than 3,000 copies of this 65,000 page reference work have been sent to Foundation mem-bers, legislators, state and local officials, libraries, newspapers, research agencies, high schools and colleges. Among the agencies in this area which have received copies of this latest Utah Foundation publication are this newspaper, the Salt Lake County Public Li-brary, Salt Lake County Library and the University of Utah Li-brary. National Cemetery Proposed For S. L.'s Fort Douglas A bill to establish a national cemetery on ground already ear marked for that purpose at Fort Douglas was introduced Tuesday by Rep. David S. King of Utah. Veterans in the intermountain region would be served by a cemetery at Fort Douglas, Rep. King said. At present the region has no national cemeteries. Under a law enacted by Con-gress in 1948, all veterans who died in uniform or received an honorable discharge, and their spouses, are eligible for burial in national cemeteries the congress-man said. In 1948 the Secretary of War set aside 100 acres on the Fort Douglas reservation for a na-tional cemetery. "Since the nearest national cemeteries are at Portland, Ore. and For Logan, Colo., the veter-ans of Utah, Idaho and the other intermountain states are entitled to see that land used for the purpose for which it was set aside," Mr. King said. |
