Jazz clarinet, rhythm guitar or virtuoso violin. A wide range of musicians can play those sounds and hundreds more with the IBM Music Feature, a special adapter card which turns an IBM personal computing system into musical instruments suitable for...
The instruments in the control room at DuPont's Victoria Texas plant serve both as a reporter and regulator. A meter, for example, controlling the flow of a liquid sends a report to another device set to the required standard. A third instrument...
Injection molded from FM-1 nylon, these spools for electric coils actuating aircraft instruments resist operating temperatures which distort other thermoplastics. Their 0.012-inch wall thickness is far less than required with other molding powders...
Small parts molded of Zytel nylon resin. Shown in the picture reading in diagonal rows from upper right hand corner are: needle adaptor for blood donor set; high pressure valve seal, contact block for aircraft instruments, wire connector; high...
This combination tongue depressor and flashlight is made with Lucite methyl methacrylate resin. The crystal clear plastic conducts very little heat. It therefore is ideal for surgical purpose. This is one of many surgical instruments utilizing...
Illumination of the sinus is achieved by the use of Lucite acrylic resin in this surgical instrument. Lucite conducts very little heat. It therefore is ideal for surgical purposes. This is one of many surgical instruments made from the plastic...
This Geiger-Muller counter is mounted on a stand of Lucite acrylic resin. Described as the most sensitive instruments known to man, such counters measure the degree of radiation from radioactive substances. They were used widely in determining...
