Popcorn on a String

It may look as if John Stemniski is holding popcorn on a string, but actually it's a model of a component of poly (bromo-

:. trifluoroethylene) telomer damping flu id, precision-sea led - 100,000,000: 1. Damp­ing fluid is a high-density, high-viscosity material that is used in inertial measuring units as the flotation medium. Dr. Stemniski, Principal Chemist in the Mini­cam Chemistry and Materials Laboratory, has been studying the physical and chem­ical properties of telomer fluids for the past seven years. Through the work of his laboratory, significant improvements in fluids have been established.

One of the most significant accomplish­ments is the development of a reliable synthetic procedure for Poseidon type inertial components. An alternate source for this highly critical material was made available, working in cooperation with PCR, Inc., Gainsville, Florida. Prior to this, damping fluid was a sole-source material.

This fluid type, while it performs reason­ably well, has several disadvantages. For example, it is composed of molecules of varying chain lenghts - similar to differ­ent lengths of spaghetti. Th is causes differences in molecular motions and the subsequent occurrence of mass unbalances in gyros and accelerometers. Improve­ments have been made but to e Ii mi nate problems associated with a mixture, a single molecule is necessary. A single mo­lecular species fluid with a density of 2.35 grams per cubic centimeter has been

While a major portion of the laboratory's efforts are directed to fluids studies, other areas of non-metallic materials are also being explored. These include epoxy studies, cleaning methods, thermal analy­sis, molecular separations, contamination identification, as well as product evalua­tion.

Grad to Walk on Moon

On April 20th, the Apollo 16 astronaut, Charles M. Duke, Jr., will be the tenth man to walk on the moon - a walk he started nine years ago at the Draper Laboratory.

A Lt. Col. in the U.S. Air Force, Duke received his Bachelor of Science degree from the U.S. Naval Academy in 1957 and did the graduate work with which he earned his S.M. from MIT at the Draper Lab. He wrote his thesis, "Human Per­formance During a Simulated Apollo Mid­Course Navigation Sighting", in 1964 under the supervision of James Nevins (23D) and Prof. Laurence Young of the Department of Aeronautics and Astronautics.

According to Jim Nevins, Director of the Man-Machine Systems Division of the Apollo Project, Duke evidenced a strong desire to become an astronaut while work­ing on his thesis. Nevins refers to T-385 as - "A significant work to determine astro-

naut performance for this sighting task".

Duke left the Institute to become a student at the Aerospace Research Pilot School in 1965. It was there in 1966, as an Instructor, that he was notified by NASA of his selecf tion as an astronaut.

Joshua Collins (46) who assists Jim Hudson in the Color Lab, prepares enlarger for color printing.

The new Kodak PMT (Photo-Mechanical Transfer) process is now one of the most widely used of the graphic arts services offered by the Photo Lab. Th is process produces high quality line and halftone copies at 1:1, enlarged or reduced, in a minimum of time. PMT copies can be made on either paper or transparent film. Although most of the transparencies are used for VuGraphs, they also make ex­cellent masters for blue-line reproductions.

The Photo Lab's main office and studio is located in D L 1-409. A complete color processing printing facility is located in DL6, while a studio and darkroom are also maintained in DL7.

ff you have any photography problems or questions about the above services, contact Bill Stirling at extension 3530, he'll be happy to help you.

Fuzz Bowl

It has nothing to do with gyros, P IGA's or gimbals - a FUZZ BOWL, according to Ken Norton (38), is a game between the Fuzz (police) and the Freaks (local college students).

Ken, a Machinist A at the Bedford Flight Facility, is active in Project Turnabout, the Drug Rehabilitation Center sponsoring the game this month in Foxboro.

Ken, who came to Draper six years ago, has been working with Project Turnabout for two years. He assists in the orientation of parents whose children have come to the Center for help.

Ken also talks with concerned adults and explains the concepts and facilities of Turnabout. This is a self-help program which has been in existence for two and one-half years. Addicts who arrive at Turnabout usually stay from six months to a year. Five facilities are maintained in Brighton, Roxbury, Newtonville, Hull and Hingham.

Ken can be reached at extension 812-201.

PEOPLE: Robert Yarrington

Bob Yarrington is a Project Technician with the Minicam Testing Laboratory at D L 1. He joined the Laboratory in 1961 as a Tech C (Electrical) after being dis­charged from the U.S. Navy. In the 11 years he has been at Draper Lab, he has been involved with angular and Z-axis alignment of the various instruments fab­ricated by his group. He has worked on PIGA's and PIP's and is presently con­cerned with the SFIR, 13 IRIG, and size-12 PM PIP.

Bob is originally from Virginia and was graduated from Middlesex High School just before he entered the Navy. During his ten years in the Service, he circled the globe and was stationed in the Med­iterranean and the North Atlantic. While

serving as a Naval Radar Operator (RD 2nd Class). he was awarded the European Occupational Medal, the Good Conduct Award, and the National De­fense Medal.

Bob received the majority of his technical education in the Navy and believes that it is a good training ground for those in­terested in becoming technicians. Bob emphasizes the need for patience, neat­ness, and curiosity in a good technician.

Although much of his time is spent work­ing with machines, Bob stresses the im­portance of teamwork. He enjoys his job because he enjoys the people he works with. Classified as a Project Tech­nician, he also serves as the temporary supervisor for 19 men when his own supervisor, Emmett Robb is absent from Draper Lab.

According to his supervisor, Bob's con­tributions regarding techniques, proce­dures, and equipment have been invalu­able. In addition, he has fabricated breadboards and consoles and has trav­eled to Milwaukee- New York- Florida -al I over the country for the purpose of instructing vendor personnel on Draper Lab techniques.

Bob and his wife, Marie, I ive in Norfolk with their four sons and daughter, Paul, Robert, David, Thomas, and Diane Marie. Both Bob and his wife have participated in the St. Jude's Bowling League, but Mrs. Yarrington now divides her spare time between working with the Norfolk Women's Club and attending a course in ceramics. In addition to his affiliation with St. Jude's, Bob has assisted in coaching the Giants, a Norfolk Little League Team.

Project News

Members of the Digital Computation Group (33) working with Pieter R. Mimno are making good progress on their program for the development of an interactive display system for use with the Draper Lab's IBM System 360/75 computer.

The interactive display system consists of a TV display and a minicomputer inter­faced with the central IBM system with software to perm it the programmer to interact directly with the computer in a time-sharing mode. The user is able to generate both alphanumeric and graph­ical display on his terminal using programs running on the IBM 360/75.

The work was started several years ago with support from the FBM and NASA programs. More recently, such diverse agencies as Data Disc Inc., the First Na­tional Bank of Chicago and the Air Force Rome Air Development Center have spon­sored parts of the work on the system. The program has been structured by its research­ers so that each sponsor receives an imme­diate response to a current requirement. At the same time, progress is advanced toward the goal of a fully supported dis­play facility at the Lab.

Blood Platelets

Normal human blood contains large num­bers of tiny particles called "platelets", which are important in preventing bleed­ing. When a person is not able to make enough platelets, tiny hemorrhages (and sometimes black-and-blue spots) usually appear in the skin, and there may be dan­ger of serious bleeding. Many of the pa­tients at the Jimmy Fund Platelet Labora­tories have th is problem from time to time. Th is condition can be treated with platelet transfusions, which sometimes have to be given every day in large amounts.

To meet this need, a method has been de­veloped for extracting platelets from a healthy donor's blood and immediately returning the blood to the donor. This can be repeated at frequent intervals with­out harm to the donor.

The need for platelets is very great, and can be met only by the constant participa­tion of a large number of donors. By par­ticipating as a donor, you will be playing an important role in the care of these children.

For further information about joining in this life-saving program, please contact Bob Schiesser at extension 3434.

Government Security Inspection

The laboratory as a Department of Defense contractor is inspected regularly on a quarterly basis by government representa­tives to insure our compliance with the federal security regulations which form a part of every classified contract undertaken by the laboratory. The inspectors have frequently commented on the large volume of classified documentation spread through­out the laboratory. Understandably, much of this material is needed for reference or for current use, and thus must be retained. A periodic review of one's collection, how­ever, as to both legitimate need and curren­cy would do much to help reduce thr classified load, and would be a demonstr~ tive effort to cooperate. Purged classified documentation may be surrendered to the library for destruction or re-issue.
