Title: Improvements in an assembly for an air launched electronic unit
IPC: G10K11/00
Filed: 1965-03-25
Abstract: 1,099,593. Marine signalling apparatus. SANDERS ASSOCIATES Inc. March 25, 1965 [March 26, 1964], No. 12770/65. Heading G4F. [Also in Division E2] An assembly for an air-launched electronic unit for launching into water from the air, comprises a housing 16, a releasable cap 13 mounted on the housing, the cap having a welllike cavity 33 therein, a spring-biased button 31 mounted for movement within the cavity, a bore 47 in the cap communicating with the cavity, a cap-release pin 42 slidably mounted in the bore for movement between first and second positions, a spring 43 for urging the pin from the first position to the second position, the pin when in its first position engaging a portion of the housing to retain the cap in position, the pin having an end portion 49 which is pressed against the periphery of the button by the spring, the button being movable against its spring bias upon the action of an hydraulic force generated by the movement of the unit in the water to permit the pin to move to its second position and disengage itself from the housing to permit the release of the cap from the housing. As shown, the button is a loose fit in the cavity so that a space is provided between the button and the side wall 38 of the cavity to allow a passageway for air into the cavity after the assembly has been dropped from an aeroplane and before it reaches the water and this prevents premature release of the cap by movement through the air. When the assembly reaches the water, if the housing is in the wrong position, the first few feet of travel in the water acts on a finned stabilizer cap provided at the opposite end of the housing to the cap 13 and turns the housing so that the cap 13 faces the direction of movement; the velocity of the assembly through the water then causes depression of the button and release of the cap. Then in the case of a sonobuoy, a hydrophone and a weight connected to the housing by an electrical suspension cable drop from the housing and the buoyancy of the housing takes it back to the surface of the water. The finned stabilizer cap is also ejected by means, not described, and an antenna is erected. A rib 48 spans the opening at the mouth of the cavity to prevent inadvetent touching of the button during handling; if desired, this can be omitted and a removable adhesive patch substituted.

Abstract: 400,983. Photographic twin-lens rollfilm cameras. KNIGHT, F. G., Rodney Hotel, Cheltenham, Gloucestershire. May 4, 1932, No. 12833. [Class 98 (i).] A camera of the kind embodying a viewfinding chamber fitted with a mirror which projects a full-size image on to a hooded focusing-screen in the top of the camera is provided with a removable carrier for the film-spools which is so constructed that, when the carrier is inserted into the camera, the supply spool rests at the front of the camera in the angular space between the angles of view of the finderlens and the taking lens. As shown, the camera has a taking compartment d separated by a curved partition b from a finder compartment c fitted with an inclined mirror f and focusing-screen l surrounded by a hood y. The finder lens k and taking lens g, mounted on a common panel h, are connected to the camera front by bellows i<1>, i, preferably separate, and are moved together for focusing as by common rack and pinion mechanism n. A shutter g<1>, with or without a diaphragm, controls the exposure, and a focal plane shutter o may be fitted. The film spools e, e<1> are carried by a light-tight box d<1> adapted for insertion through a rear door a<1>. The upper wall e<5> of this box is hinged at e‹ so that, when the box is inserted into the camera, the wall may first occupy the dotted position to allow the supply spool e to clear the downwardly-projecting part of the partition b, and may then be raised, as by the co-operation of pins e<10> on the spool casing e<4> with cam slots a<4> in the outer casing a, in order to lift the spool e into position against the front wall and between the fields of the lenses k, g. The spool e may be held in the casing e4, which is of cylindrical form cut away at e9, by pins e<12> on L-shaped members e<11> oppositely slidable against spring action to release the spool when finger pieces e<13> thereon are pressed towards each other. The take-up spool e<1> is carried by the usual spring arms e<2> hinged at e3 to the base of the box d<1>, and is operated by the usual axially-displaceable winding key. A spring-pressed plate a<3> on the door a<1> presses the film flat against the focal aperture during exposure.

Filed: 1940-08-12
Abstract: 542,089. Catalytic apparatus. DISTILLERS CO., Ltd., STANLEY, H. M.. and PHILIP, T. B. Aug. 12, 1940, No. 12904. [Class 1 (i)] [Also in Group IV] Halides such as vinyl halides are obtained by re-acting acetylene or its homologues with a hydrogen halide in presence of a metal halide catalyst, the amount of hydrogen halide being insufficient to re-act with all the acetylenic hydrocarbon, and then adding further hydrogen halide to the re-action gases and repeating the re-action one or more times without removal of the halogenated hydrocarbon between the operations. The reaction temperature may be maintained constant by surrounding the reaction chamber with a boiling liquid. The catalyst may be on a porous support and vapour of the catalyst entrained by the re-action gases may be absorbed in a final packed chamber which when thus charged with catalyst may be removed to become the first catalyst chamber while the initial first chamber is transposed to act as absorber. The catalyst may be mercuric chloride on active carbon, silica gel or pumice. Specification 21134/13, [Class 2 (iii)], is referred to.

Title: Improvements in or relating to rotary pumps
IPC: F04B43/00
Filed: 1954-05-06
Abstract: 764,494. Rotary pumps. NICOTRON DEVELOPMENTS, Ltd., and JAPOLSKY, N. S. Aug. 4,1955 [May 6,1954], No. 13241/54. Class 110 (2). A rotary pump provided with one or more rollers driven by a central driving-shaft and so mounted that the roller axis or axes rotate about the axis of the shaft has at least one fluid conduit with walls of resilient material extending helically around the shaft and enclosed by a casing. Moreover, as the shaft rotates, the roller or rollers contact the conduit walls producing a moving constriction in the conduit which causes a series of peristaltic pumping waves. The driving-shaft 4 is supported by bearings 5 mounted in the end covers 2 of the pump casing, each bearing being held in position by a locating nut 7 and a cover 6. A resilient tube 10, e.g. of rubber is helically wound within the casing, the tube ends (not shown) being carried tangentially through the casing, and a second tube 11 of smaller diameter than the first being wound between the coils of tube 10. Both tubes are held in position by rings 12, 13. Flanges 14 of the shaft 4 have peripheral recesses in which are mounted, by means of ball-bearings 16, the axles of rollers 15 held in the recesses by spideis 17. The rollers which are solid can move radially in the recesses. Rotation of the shaft carries the rollers around the axis of the shaft and causes them to roll on the tube 10. The rollers move radially outwards due to centrifugal force causing constrictions in the tube 10, which constrictions move along the tube with the rollers. The tube 11 is used to support the tube 10 and increase its resilience. The tube 10 may be reinforced with metal wire, nylon thread or strong fibre. Diffusers may be provided at the inlet and outlet ends of the tube 10 to convert pressure into velocity and vice versa. Several tubes may be arranged in parallel. In a modification, Fig. 3, flanges on the casing form ports 24 communicating with toroidal passages 25. The rollers 33 are rotatably mounted by means of bearings 34 on shafts]32 which have sliding fit in radial recesses of flanges 31 on the driving-shaft. The resilient tubes are replaced by a hollow rubber insert 38 having a thick wall through which extend helical channels 39 communicating with the passages 25. Annular extensions 43, 44 of the insert are sucked into grooves 41 in the end casings 22 to form a fluid seal by applying a vacuum to holes 45 communicating with the grooves. The ports 24 are similarly sealed to inlet and outlet pipes. For pumping fluids at high pressures through the channels 39, the space within the pump may be partially filled with liquid introduced through a passage 40 in the end casing 22, the liquid filling being carried round by the rollers during working of the pump and so increasing the centrifugal force.

A thread rolling machine includes, for each of two driving spindles 1 and 2 carrying thread forming rolls 3 and 4, a brake 30 which is applied, in order to eliminate free play in the drives to the rolls, in synchronism with feeding movement of one of the rolls. The roll 1 is mounted on a fixed frame 36 of the machine, while the roll 2 is mounted on an hydraulically movable carriage 18, both rolls being driven through gearing from a common motor 15. As the roll 2 is fed towards the roll 1, a controller 25 arranges that hydraulic fluid under pressure is communicated through a pipe 29 to operate a pair of brakes 30. The pressure is released when the roll 2 is returned. Each brake includes an axially movable disc 41, Fig. 3, which is urged against the flange 42 of a sleeve 43 keyed to the roll spindle. A radial projection of the disc is located between set screws, and the disc may be provided with springs 48 to maintain the disc in light contact with the flange when the hydraulic pressure is released. The pressure supplied by a pump 23 to the brakes and the piston 20 is adjustable by valves 31 and 32 and is indicated on gauges 35 and 24, respectively.

Filed: 1941-10-18
Abstract: 565,464. Electricity supply. SPERRY GYROSCOPE CO., Inc. Oct. 18, 1941, No. 13436. Convention date, Oct. 19, 1940. [Class 38 (iv)] [Also in Group XXIV] A motor 1, through gearing 2, drives, in opposite directions, one side of a pair of differentials, the other side of which is geared up to a driven member 6. Each of the differential reaction members 8, 9 is geared to a fluid pump P which draws from a reservoir 24 and delivers past piston valves 20, 20<SP>1</SP>, back to the reservoir 24. The valves 20, 20<SP>1</SP> are moved bv a common control member 17. When the latter is moved to one side or the other of the neutral position shown, one or other of the differentials is rendered effective to drive the member 6 in one or other direction. As shown, the planetary spiders are the reaction members. In a modification, the pumps P are geared to one of the sun gears of the differentials. In another modification, a motor 30, Fig. 3, drives one side of differentials 31, 32, the other sides being connected for driving dynamos 33, 34. The latter have loads 37, 38 and the field windings 35, 36 may be varied by a potentiometer 39 which may be controlled by a gyro unit 41. The spider gears 43, 61 of the differentials are oppositely connected through gearing to a driven member 46. In operation, according to the position of the tap 40 of the potentiometer, the member 46 will be moved in one or other direction according as the voltage supplied to the field winding 35 is greater or less than that supplied to the field winding 36. In a modification of this arrangement, the machines 33, 34 may be wired so that one acts as a motor and the other as a generator. In another modification, Fig. 4 (not shown), field structures 50, 51 of dynamos 52, 53 are driven in opposite directions by motor 30. The armatures 56, 57 are interconnected by leads 58 in series opposing and act through gearing 59 to drive a member 62. A gyro unit 48 acting through an amplifier varies the voltages in the field windings and the member 62 moves one way or the other according as the voltage in one winding is greater or less than the voltage in the other winding. Specification 538,526, [Group XXXIII], is referred to.

Abstract: 688,051. Ion exchange processes. PERMUTIT CO., Ltd. May 31, 1951 [May 31, 1950], No. 13626/50. Class 46 [Also in Groups II and XXXV] In an automatically controlled system for maintaining the alkalinity of a water supply' at a required value, alkaline water is blended with acid water, and the electrical resistance of a sample is compared with the electrical resistance of the mixture plus further acid water, the ratio of the blend being adjusted accordingly. Some of the untreated water entering at 1 passes through a tank 3 containing base-exchange material, and emerges alkaline. The remainder passes through a tank 5 containing hydrogen - ion - exchange material, and emerges acid. The two effluents pass through valves 8, 9, and are blended. A sample of the blend is passed to a constant level tank 13 from which outlets 14, 15 supply test cells 16, 17. A sample of the acid water is also supplied to the cell 16 via a constant level tank 19. It is shown that the conductivity of the water is a minimum when the water is neutral and rises with increase of either acidity or alkalinity. The amount of acid water added to the cell 16 is proportioned so that the electrical resistance of this acidulated sample is equal to or has a predetermined difference from the resistance of the normally alkaline sample in cell 17. Any variation in the alkalinity of the blended water causes a relay 25 to actuate a reversible electric motor 26 to differentially operate the control valves 8, 9. The automatic control system may alternatively be electromagnetic, hydraulic or pneumatic, or a variable speed pump may add the acid water to the alkaline.
