Title: Apparatus and method for preparing explosives
IPC: C06B21/00
Filed: 1965-11-01
Abstract: A continuous process for preparing explosives comprises feeding wet explosive through a protecting wall on to a vibrating conveyer where it is dried by hot air, weighing automatically into containers and discharging through a protecting wall, movable shields in the protecting walls being adapted to close when explosive is not passing through the walls.  Wet initiating explosive is fed, Figs. 4-6 (not shown), through a protecting wall by means of a chain conveyer carrying a container.  An automatically operated clutch reverses the direction of the feed conveyer when the container has discharged. By means of cams, shielding plates are raised and lowered in time with the passage of explosive through the wall.  Each container discharges into a granulator and the granules pass on to a preliminary conveyer, Figs. 10-12 (not shown), which includes mesh to remove coarse and fine grains.  The main drying conveyer, Figs. 13-15 (not shown), is vibrated by means of motors and is stepped so that the explosive turns over during drying.  Hot air is fed into compartments underneath the conveyer. The weighing and discharge apparatus is shown in Fig. 18.  Dry explosive passes from the conveyer 3 through funnel 134 to an automatic device (see Division G1) which introduces a weighed amount into a container 82 at position D.  The container is carried by chain conveyer 81 through protective wall 13A to position E where the container is removed and the direction <PICT:1104039/C1/1> of the conveyer is reversed.  By means of clutch and cam mechanism, the movement of the conveyer is correlated with the automatic weighing and with th raising and lowering of shielding plates 105, 105A.

Abstract: 1,136,841. Automatic tension control. S. DAVALL & SONS Ltd. Feb. 25, 1965 [Nov.25, 1963], No.46516/63. Heading G3R. In a system for controlling the feed of elongate material from a reel, means for taking up slack and thereby applying tension to the material progressively controls the speed of drive to the reel and also initiates braking of the reel if the amount of slack becomes excessive. In a magnetic wire recorder, Fig.2, the wire 41 passes over pulleys 51-64 between reels 42, 43 on which the wire is wound. Recording and erasing heads (not shown) are suitably positioned and the wire is moved by driving a capstan 56 and reels 42, 43. Movements of spring-loaded levers 74, 75, which apply tension to the wire by pressure on pulleys 55, 59, respectively control the speeds at which reels 42, 43 are driven so that loop size and hence wire tension is maintained constant on each side of capstan 56. Lead screws 69, 71 respectively driven with reels 42, 43 continuously, move pulleys 51, 64 across the reels to facilitate even distribution. If loop size varies unduly, movement of lever 74 or 75 operates a cam 78 or 79 sufficiently to move a pawl 83 or 84 into engagement with a ratchet wheel 87 or 91 so that one or other of the reels is braked to restore loop size according to the direction of movement and according to whether the loop is too large or too small.

Title: Fabrication of semiconductor devices incorporating polycrystalline  silicon
IPC: H01L23/52
Filed: 1972-10-12
Abstract: 1384153 Semi-conductor devices RCA CORPORATION 12 Oct 1972 [20 Oct 1971] 47217/72 Heading H1K In the manufacture of a semi-conductor device silicon is vapour deposited on a substrate maintained at a temperature less than 700‹ C. so as to be insulating (10<12> ohm. cm. resistivity) and is then annealed at about 1100‹C. to convert it into semi-conductor form, dopant atoms being incorporated in the layer at some stage. The substrate may be of quartz, ceramic, sapphire, spinel, silicon or germanium with or without a coating of metal, semi-conductor oxide or nitride. As described the silicon is deposited at a rate of 2Á/hour from a mixture of silane, hydrogen and a source of dopant (arsine or borane) on silicon held at 600‹ C. in a tube which has been purged first with nitrogen and then hydrogen and is purged after deposition with hydrogen. It is annealed by heating to 1100‹ C. in hydrogen. Typically the process is used in making an integrated circuit comprising a bipolar transistor and an IGFET. After forming the source and drain of the IGFET and base and collector of the bipolar transistor in a P type silicon wafer by conventional diffusion the overall oxide layer is apertured over the base region and the insulating silicon, containing 8 x 10<15> atoms/c.c. of arsenic is deposited to a thickness of 1Á and then, if desired, overlaid with a 3000A layer of silicon nitride or dioxide to prevent subsequent outdiffusion of the arsenic. Annealing for ¢ hour in nitrogen at 1100‹ C. renders the deposited silicon conductive and causes arsenic to diffuse therefrom to form the emitter region. The silicon is then shaped by photolithography using the nitride or dioxide as an etch mask, to form the emitter electrode of the transistor, the gate of the IGFET and track interconnecting them. Aluminium contacts are then provided conventionally on the remaining regions of the devices.
Patent GB-475550-A (GB)
Abstract: 475,550. Transfer mechanism. KOOPERATIVA FORBUNDET, FORENING U. P. A. May 18, 1936, No. 14035. Convention date, May 22, 1935. [Class 106 (i)] In a calculating-machine having a totalizer engageable optionally with differential actuators or with gearing communicating with total retainers having no transfer mechanism, the transfer mechanism for the totalizer comprises members movable by the totalizer wheels from an inoperative to an operative position whether the wheels are in engagement with the actuators or with the communicating gearing, means being provided to retain such a member in operative position for the purpose of imparting one step of movement to the actuator of next higher order. The totalizer wheels 1 are freely rotatable on a shaft 2 carried by a frame 3 that is horizontally slidable by cams 8, 9 to engage the totalizer with differential actuator racks 33 or with gears 58 communicating with total retainers. Supposing a transfer to occur with the totalizer in engagement with the actuators, a transfer tooth 13 wipes past a cam-shaped part 22 of an arm 14 pivoted to the frame 3. The arm is thus shifted from the position shown in full lines to that shown in dotted lines where it is held by a plate spring 21. Now, upon the elevation of a slide 41 by cams 42, 43, a transfer member 48 carried thereby is shifted to the left by the co-operation of its stud 54 with the lefthand side of the arm 14. Continuing its upward movement, an offset arm 51 of the transfer member abuts a shoulder 60 of the actuator of next higher order and displaces it one step relatively to its setting member 26 whereby one unit is added into the totalizer wheel of that denomination. The actuator is maintained in displaced position by a plate spring 36 until it is restored by the abutment of a shoulder 55 on the slide 41 with a lug 40 during the downward movement of the slide. The pairs of cams 42, 43 are helically arranged to effect subsequent transfers. The arms 14 are restored by cams 25 on a shaft 6. When the totalizer is engaged with the gears 58 and a wheel passes through zero, the associated arm 14 is rocked as before and transfer is subsequently effected with the totalizer in engagement with the actuators. The invention is described as applied to a machine having two totalizers, the wheels of which are interspersed on the shaft 2 and co-operate with pairs of actuators, each pair being carried by a setting member. Specification 465,402 is referred to.

Title: Container filling apparatus
IPC: B67C3/12
Filed: 1971-10-15
Abstract: 1372566 Counterpressure filling machine CONTINENTAL CAN CO Inc 15 Oct 1971 [15 Oct 1970] 47995/71 Heading B8T A counter pressure container filling machine for carbonated liquids has means for creating extreme turbulence and a high pressure drop in the product delivery line immediately prior to entering the filling head in order to minimize foaming. An open top container (C), Fig. 1 (not shown), is positioned below a sealing bell assembly 20, and a movable valve housing member 14 lowered by box cam 16 to seal the container on rubber ring 21. Counterpressure valve 61, opened by operation of cam 97, supplies pressure from input tube 60, via passageways 63-65 to valve assembly 30 and into container C. As the pressure in the container C equalizes, back pressure on piston 48 raises valve 30 and opens product line 36 and valve 33, and the carbonated product, which is in a highly turbulent state after passing through restrictor 125, which also produces a high pressure drop, passes at high speed with a minimum of foaming through passage 35 into recess 31 past open valve 33 into guide core 23 and into container C. The counterpressure lifting piston 48 also engages upper tip 59 of probe 45 with contact 57, so that when the liquid level in the container C rises to latch the bottom of probe 45, an electrical circuit actuates valve 80, opens it and admits compressed air above piston 48 to close valve 30 and shut off product line 36. Counterpressure gas flow back through line 60 and valve 61, and when the container is filled cam 97 closes valve 61, housing 14 being raised by box cam 16 to release the filled container. As housing 14 reaches its uppermost position, magnet 93 operates normally closed switch (94), Fig. 8 (not shown), to reset the apparatus for the next container. The compressed air operating piston 48 is exhausted through passageway 87. An automatic control to prevent supply of counterpressure or product is incorporated if the container is absent. Restrictor 125 may be of different forms, e.g. small bore pipes, twisted vanes &c.

Abstract: 1320242 Revolving cylinder pumps and motors; leakage LINDE AG 9 Oct 1970 [10 Oct 1969] 48036/70 Heading F1A [Also in Division F2] The interior 16 of an axial piston hydraulic pump or motor housing 3, 4 communicates with reversible inlet and outlet ports 11, 12 via passages 13, 19, 17 and 14, 21, 18 respectively, each passage including a one-way valve 20 or 22. The pump or motor has a rotary cylinder block 2 in which pistons 8 are reciprocated by co-operation with a swash plate 10. If ports 11, 12 communicate with low and high pressure lines respectively, then the valve 22 on the high pressure side will be closed. However, if fluid leaks past piston 8 and increases the pressure in the interior 16  to a level above that of the low pressure side then valve 20 will open and permit flow to the low pressure port 11. Thus a predetermined low pressure is maintained in the interior 16. The interior 16 may be pressurized by a feed pump, Fig. 2 (not shown) or gas-loaded pressure vessel, Fig. 3 (not shown).
