Filed: 1964-04-13
Abstract: 1,023,098. Sample injector for gas chromatography. MICROTEK INSTRUMENTS Inc. April 13, 1964 [April 11, 1963], No. 15192/64. Heading B1L. [Also in Division B8] An injector for insertion into the sample vaporization chamber of a gas chromatograph comprises a thin-walled capillary tube open at one end and closed at the other and attached to a shaft aligned therewith, the capacity of the tube being 0À2-5 Ál. while the ratio of length to inner diameter is 10:1 to 200:1. The device may be used to inject liquids or solids into the sample vaporization chamber. In a specific embodiment an adaptor situated above a washbottle receives the injector capillary tube in a conduit whilst a syringe needle is located in the tube by means of another conduit of the adaptor. Thus the tube may be readily filled, while the excess of liquid drains away to the wash bottle. The adaptor may be made of a transparent substance; alternatively the adaptor may be made of translucent or opaque material. The injector is then transferred to conduit 19, Fig. 3, of the sample inlet system of a gas chromatograph. The diameter of conduit 19 and shaft 11 are such that no gas can pass between them. Line 18 introduces carrier gas which flows out through conduit 16 since ball valve 17 is closed. On opening valve 17, the injector is passed down the conduit 19 and the tube 10 located in conduit 16 since it has the same outer diameter as the inner diameter of the conduit 16. Heater 20 vaporizes the sample. When a solid sample is analysed, a detachable tube may be used and the sample tamped down into the tube. A plug in the tube can limit the volume of the tube.

Abstract: 1,246,212. Accelerometers; detecting movements photo-electrically. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT METROLOGII IM, D. I. MENDELEEVA. March 25, 1969, No.15521/69. Headings G1A and G1K. Accelerations of a mass are measured by locating on the mass the moving mirror of a Michelson interferometer. The mass 1, accelerated upwards by discharge of capacitors 11 through a moving coil 12, is decelerated rapidly by an impact block 3. Light from a laser 7 is reflected from mirrors 6 and 9 and the interfering reflected light is detected by a photo-multiplier 10. The speed of the mass is determined from the frequency of the interference beats from photo-multiplier 10 and the speed is differential to determine the acceleration of the mass. The mass 1 may carry an accelerometer 2 under calibration. For accelerations up to 200g, the moving coil 12 suffices, and the impact block is not used. In a modification, Fig. 2 (not shown) the mass is held at a predetermined height by an electro-magnetic latch and then allowed to fall on to a stationary impact block or an electromagnetic exciter moving against the mass.
