Title: The determination of conditions of motion
IPC: H01S3/139
Filed: 1966-06-13
Abstract: 1,108,835. Lasers. LITTON INDUSTRIES Inc. 13 June, 1966 [17 June, 1965], No. 26331/66. Heading H1C. The conditions of motion of a body to which a laser is attached are determined by varying the optical path length of the laser in accordance with the motion and monitoring the laser output interferometrically. Laser resonator mirror 54 is mounted on a proof mass 56 resiliently supported by leaf-springs (not shown). *Acceleration of the device varies the distance between mirror 54 and mirror 52 of helium-neon laser 10, which shares a common gas envelope 14 with a laser 12. The outputs from the two lasers are directed on to a photo-detector 82, the rectified and amplified output of which is supplied to a counter 90 which counts the number of cycles of the beat frequency produced by interference between the light beams. As shown, the output of the counter may control the position of potentiometer slider 94 to vary the voltage applied to piezo-electric crystal 62, one electrode of which forms reflector 60 of laser 12, so that laser 12 tracks laser 10 to eliminate the beat frequency. Alternatively the counter output may be used to restore mirror 54 to its undeflected position so that laser 10 tracks reference laser 12. If neither mirror is repositioned the counter output indicates the velocity of proof mass 56.

Title: Improvements in or relating to methods of diffusing phosphorus into silicon
Inventor: NASSIBIAN ARMENAG GARABEG
IPC: C01B25/02
Filed: 1962-07-11
Abstract: Phosphorus is diffused into silicon by passing a stream of inert gas first over a heated mass of phosphorus, then over a heated silicon body, and introducing a flow of oxygen into the stream of gas between its passage over the phosphorus and its passage over the silicon. The concentration of phosphorus at the surface of the silicon after completion of the deposition process is controlled by appropriate choice of the ratio of the rates of flow of oxygen and inert gas, and of the temperature of the phosphorus source; the preferred ratio being not less than 0.2 and the temperature of the phosphorus being 250-400 DEG  C.  The silicon may be maintained at 900-1200 DEG  C. The process may be carried out in a horizontal tubular silicon furnace chamber formed in two parts, one having diameter 6 cm., length 160 cm., the other diameter 3 cm., length 50 cm., the two parts being joined end to end and separated by a partition.  A silica tube 1 cm. diameter, 45 cm. long, projects through the partition for a short distance into the larger part of the chamber; the remainder of the tube is within the smaller part and is folded so that its other end is near the partition. A side-tube for admission of oxygen opens into the larger part of the chamber about 1 cm. from the partition. The furnace chamber is surrounded by a number of heater elements arranged so that a first zone disposed about halfway along the length of the smaller part of the chamber is maintained at 250-400 DEG  C., a second zone extending from the first zone to the partition is maintained at 500 DEG  C., and a third zone extending from close to the side-tube along the major part of the larger part of the chamber is maintained at 900-1200 DEG  C. In carrying out the process, silicon bodies are disposed within the third zone and phosphorus in the first zone.  A stream of purified nitrogen is fed to the free end of the smaller part of the chamber, and finally leaves at the free end of the larger part.  Reference has been directed by the Comptroller to Specification 909,869.

Abstract: 1476784 Silverware sorter AVANT INDUSTRIES INC 19 June 1974 [20 June 1973] 27138/74 Heading B2H [Also in Division B8] In an apparatus for sorting silverware including knives, forks and spoons, means for feeding the silverware to a sorting bed 42, Figs. 1 and 3, comprises a hopper 10 for collecting the silverware in bulk amounts, means 16 for discharging the silverware from the hopper, a trough 30 for receiving the silverware discharged from the hopper, and an impact surface 36 positioned so that silverware discharged from the trough falls on to the surface and is spread substantially evenly over it upon impact. The hopper 10 is mounted on resilient supports 14 and is vibrated by a vibrator 16 to cause the silverware to move to its discharge end. The hopper is grooved over the whole or part of its bottom. The trough 30 is mounted on flexible members 32 and vibrated by a vibrator 34. The impact surface 36 is provided by a plate supported by side panels 28 of a grooved conveyor bed 38 mounted on flexible members 40 and vibrated by a vibrator 39. The silverware on the impact surface is thus delivered on to the bed 38 and is discharged through slots 37 therein onto the grooved sorting bed 42 which is supported on flexible members 46 and vibrated by a vibrator 44. Deflector members 35 on the bed 38 serve to align the silverware longitudinally in the grooves of the bed. A pan 83 supported on the apparatus frame above the bed 42 receives from the bed 38 any overflow of silverware which has not passed through the slots 37 and which is manually transferred back to the hopper 10 for recycling. Alternatively, the pan 83 could be supported by braces 47 to vibrate with the bed 42 and the overflow would then discharge into a container 96 which also receives overflow from the bed 42. The bottom of the bed 42 is formed with series of interconnected slots 52, 62, 64 and 66, Figs. 6 and 8, which are of such shape and width as to allow forks 54, knives 56, small spoons 58 and large spoons 60 respectively to fall through them in succession into separate beds 68, 70, 72 and 74. The latter are provided with slots which allow the silverware to be deposited in respective collecting containers 82 with their working ends upwardly. The containers 82 may be in the form of baskets insertable in a dish-washing machine. The different beds may be made of extruded, moulded or formed parts which have a suitable cross-section on defining grooves between their sides and which are assembled together to constitute a bed.

This arrangement increases the energy output relative to that attainable from using a single chamber, but does not appreciably change either the generated primary pulse signature or the secondary bubble pulse attenuation characteristics. In the embodiment shown, chambers 32a, 32b, 32c are arranged in tandem and have radially extending exhaust ports 33a, 33b, 33c controlled by piston valves 34a, 34b, 34c. During charging of the generator, air pressure in control chamber 37 moves valve 34a to the right to close ports 33a, whereupon build up of pressure in chamber 32a moves valve 34b to the right to close ports 33b, and so on. The generator is fired by depressurizing control chamber 37, whereupon valve 34a moves leftwards to release air from chamber 32a, so allowing valve 34b to move leftwards and so on. The generator may be modified to adjust the brief delay between opening of the valves.
