Title: Improvements in or relating to firearm barrels
Inventor: HARTLEY JAMES C
IPC: F41A21/02
Filed: 1957-04-12
Abstract: 836,372. Firearm barrels. OLIN MATHIESON CHEMICAL CORPORATION. April 12, 1957, No. 12013/57. Classes 92 and 119 A firearm barrel comprises a thin liner 30, Fig. 2, and an outer jacket 32 of non- metallic fibres bonded to each other and to the liner in mutual stress-transmitting relation. In one form strands 44, Fig. 5, of glass fibres are wound on the liner 30 previously provided with a layer of resin binder which is also applied to the strands. The strands may be wound on the liner in different ways to give both radial and longitudinal strength to the jacket. Figs. 6-9 (not shown) indicate some of the variations. Instead of resin binders, metallic materials may be used as binders, e.g. by winding metal coated fibres which are subsequently bonded by heat and/or pressure. Instead of glass fibres, nylon or other linear polymer fibres may be used. One or all of the layers of fibres may be in the form of woven fibre tape or cloth which is wound on the liner, and the wound jacket may be covered with a woven cylindrical sleeve which is subsequently bonded to the jacket. The liner 30 may be made of various metals or alloys and may be in normal heat treated or auto-fretted condition. The liner may also be made of non-metallic material. The liner 30, Fig. 13, may be expanded by forcing or drawing a button 70 therethrough, so that the fibres in the jacket are placed under permanent tension. The button 70 may be also used to provide the rifling in the barrel liner. Instead of winding the fibres directly on the liner, the jacket may be formed on a mandrel and then slipped over the liner and bonded thereto. Alternatively fibres in the form of a mat or resin slurry may be applied to the liner and subsequently moulded to shape. The jacket may be formed of sheets or tape comprising a fibrous material and a pressure sensitive adhesive, thus eliminating the need of any other binder and the curing thereof. The jacket may also be provided with a coating of metal foil such as brass or stainless steel. The Specification also describes. several graded obstruction firing tests for the firearm barrels.

Title: Improvements in or relating to elevator systems
IPC: B66B13/14
Filed: 1955-04-27
Abstract: 775,718. Door-operating apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 27, 1955 [May 4, 1954 ; May 4, 1954], No. 12128/55. Drawings to Specification. Class 65 (1). [Also in Groups XXX, XXXVI, XXXVII and XL (b)] The door of a lift is normally closed at a predetermined interval (say 5 seconds) after stopping of the car, and this interval may be lengthened (say to 6 seconds) when the stop is in response to a call from a floor (where the intending passenger may have some distance to walk to the lift) and shortened (e.g. to 3 seconds) when it is in response to a floor-selecting device in the car. In order to expedite operation of the lift, the interval may be reduced or terminated when the car is loaded within, say, 80 per cent of capacity, and may be reduced on movement of a passenger into or out of the lift, as detected by a beam of energy (light or invisible radiation) (see Group XL (b)) or a capacitance change (see Group XXXVI); the reduction may be to 2 seconds for the first person in the case of a stop in response to a floor-call and to ¢ second for each subsequent person (renewed on the passage of each person). Two beams of energy, with separate detectors, may be used to provide a different response according to the direction of movement of the passenger, so that if the car stops in response to a floor-call (with or without a car-call) the interval is reduced only by a person entering the car and not by one leaving. A warning of impending closing may be given by any suitable means. Once the door has started to close, it may continue, or it may be reversible on contact with an obstruction, by means of a sensitive edge device, or on interruption of the beam by a late passenger, then closing again on expiry of a short period (e.g. ¢ second) after reaching the open position or after restoration of the beam respectively. If the beam is obstructed for an unduly long time (say 4 seconds) a different warning may be given, and closing is started nevertheless. If the door still fails to -close in a reasonable time (say 12 seconds), the closing may be made independent of all safety devices except simultaneous operation of the sensitive edge of the door and a similar device on the closing post or a meeting door; the movement of the door in this case may be made slower and/or with more power in part or all of the movement, by varying resistances connected to the motor, and normal closing may be restored if the obstruction is removed. The time intervals may be varied or cancelled by manual switches, in conjunction with car-position switches if the effect is desired only at certain floors, or by time-switches to provide different control conditions at peak-load hours. In one embodiment described, a lever pivoted above the door is connected to the door by a pin and slot and is actuated by opposed solenoids; in another embodiment, the lever is connected to a rack engaged by a pinion driven by a reversible motor. The shaft door is connected to the car door, for simultaneous operation, by the usual vane device.

Title: Improvements in or relating to gas-filled electric discharge devices
IPC: H01J17/56
Filed: 1937-04-28
Abstract: 494,528. Discharge apparatus. SIEMENS & HALSKE AKT.-GES. April 28, 1937, Nos. 12132 and 12133. Convention dates, April 30, 1936 and Feb. 9, 1937. [Class 39 (i)] In a discontinuously controlled gas - filled electric discharge device having at least two control electrodes, these are so spaced relatively to the cathode and anode or anode system that the influence of the anode on the potential directly in front of the cathode is greater than the corresponding influence of either control grid alone. Thus the streams of electrons formed in the vessel flow practically entirely to the anode. The sum of the influences of all the control electrodes may be much greater than or may be less than that of the anode on the cathode. The desired effect may be obtained by using two control grids having bars 4, 6, Fig. 1, which are arranged in pairs and the openings between the pairs of which are made large. Alternatively, the control grid bars may be formed as helices, those of one grid being arranged within those of the other. In a modification, which may also be provided with an anode system, consisting of an anode 34, Fig. 5, and a grid 35 at cathode or other potential, and also with an incandescent or a mercury cathode, the control grids 32, 33 are provided with interfitting bars arranged to surround the discharge path. Alternatively, the grids may be in the form of helices fitting over within the other and also arranged to surround the discharge path. The length of the combined grids should not be more than twice the diameter of the discharge path.

Title: Improvements in or relating to pressure control valves
IPC: B64D13/04
Filed: 1942-08-28
Abstract: 567,640. Safety valves. WESTLAND AIRCRAFT, Ltd., WIDGERY, W. M., and RICHARDS, S. T. A. Aug. 28, 1942, Nos. 12161/42 and 4567/43. [Class 135] [Also in Group XXXIII] A sealing gasket for aircraft pressure cabins or like spaces, is in flated to a pressure slightly in excess o: that in the cabin by connecting it to a chamber to which air is supplied through ar inlet valve loaded to a predetermined pressure, an outlet non- return valve loaded tc a higher pressure controlling communication between the chamber and the cabin, means also being provided to prevent the cabin pressure from exceeding a predetermined amount above the prevailing outside pressure. In one form, shown diagrammatically in Fig. 1, the gasket g is connected to a chamber d which is supplied while in flight from a conduit L connected to a blower, a second conduit M enabling the chamber d to be supplied from a blower while on the ground. The two conduits communicate with the chamber through two valves N, O loaded to a pressure of 1 lb. per square inch. Another non-return valve P loaded to 2¢ lbs. per square inch controls the air supply to the cabin e which has a pressure relief valve S to limit pressure difference between the cabin and outer atmosphere: The limit of pressure difference between the gasket and the cabin is limited by the loading of the valve P. In practice, the conduits M, L are formed as chambers in a casing a, Fig. 2, having guides for the valve stems of the three valves which are mounted in a separate casing b clamped thereto, only the valve N being shown, and the combined casings being secured to a cabin bulkhead. The chamber d is formed by partitions in the two casings, the valve P opening into a pocket in communication with the cabin. Fig. 8 shows another arrangement in which in addition to the valves N, 0 admitting air to the chamber d, two valves X, Y are provided, to admit air from the conduits M, L directly to the cabin, the five valves and the conduits L. M being carried by a casing corresponding to the casing b of Fig. 2. In this case, the valve P may control a restricted passage. An additional casing carries a butterfly valve u enabling the pilot to delay pressurising the cabin until a desired height is reached. The valve is coupled to a lever for simultaneously opening the valve O as the valve u is opened. In a further modification, the valve X is omitted. A vent wenables the gasket to be deflated when the valve 0 is opened after the ground blower has been in operation and brought to rest.

Abstract: 1,207,022. Computer programme efficiency. H. M. TAYLOR. 13 March, 1968, No. 12228/68. Heading G4A. [Also in Division G1] Apparatus for monitoring the amount of idle time of the different operational components of a data processor when working under the control of a programme, the components giving signals indicating whether or not they are working, comprises means responsive to these signals to measure their duration during a reference sampling period. The measurement may be analogue or digital. As described the working condition of a decoder 12 is indicated by a signal on lead 18 applied to gate 17. Clock pulses from oscillator 20 are applied to the gate and received in a " profitability " counter 26. The gate 17 is enabled for a sampling period from a source 22. While the decoder is working pulses pass to the counter 26. A further counter 27 receiving the values in counter 26 displays these values as a steady indication. The pulses from oscillator 20 are also applied via a gate not shown to be counted in counter 24 for the sampling period. Counter 24 is also connected to a display counter 25. The ratio between the values in counters 26 and 24 or 27 and 25 gives the proportion of the sampling period for which the coder was working. This proportion may be worked out in computer 50 and recorded and displayed. The source 22 includes a switch 28 by which other gates 35, 36 can be enabled for a sampling period to monitor the working time of other components, e.g. the printer and card reader. The gates 17, 35, 36 are also controlled by signals from source 62 which for example allows monitoring only when some other component is not working. The apparatus gives an indication of the efficiency of a programme, i.e. the amount of time each component is working. The programme is then modified to improve the efficiency and new tests made. A number of different programmes may be stored at 11 and different ones may be selected by a signal on lead 58 in response to the determination of efficiency in computer 50.

Abstract: 816,556. Rotary engines &c. PRENDERGAST, C. S. Dec. 30, 1957 [April 15, 1957; Oct. 23, 1957], Nos. 12298/57 and 33098/57. Class 110 (2). Sliding vane pump or motor having three circular rotors 4, 5, 6 keyed to a coaxial shaft 1 between end casings 2, 3, the outer rotors 4, 5 being provided with fixed eccentric stators 9, 10 while the eccentricity of the stator 11 of the rotor 6 can be adjusted by screw means to vary the output of the pump between zero and a maximum. Partitions 7, 8 separating the rotors have peripheral grooves 7A, 8A closed by casing rings 7B, 8B, while grooves extending over about 90 degrees of the periphery of stators 9, 10 are closed by casing rings 9B, 10B and communicate through radial passages respectively with an axially aligned passage 19 leading from an inlet port 20. Each rotor has eight equi-spaced radial grooves 15 in which vanes 16 slide, the outer end of each vane being shaped to conform to the bore of the stator. As fluid enters the stators 7, 8 from passage 19, the vanes driven outwards by centrifugal force entrain the fluid while sweeping across arcuate grooves 9C, 10C communicating with the quarter-circle grooves and force the entrained fluid through arcuate grooves 9D, 10D respectively communicating with the grooves in the partitions. In the adjustable stator 11 are two radial passages 11A, 11B communicating with an inlet port 21 and an outlet port 22 through arcuate grooves 12B, 12C, the groove 12C being in communication with the grooves 7A, 8A, so that fluid entrained by the rotors 4, 5 passes to the groove 12C and thence through port 22. When the relative eccentricity of the stator 11 and rotor 6 is in opposition to that of the outer pumping units, fluid entering by port 21 is entrained by rotor 6 and forced through outlet 22 in addition to that supplied by rotors 4, 5. If there is no relative eccentricity of stator 11 and rotor 6, the total displacement of the pump is from rotors 4, 5. When the relative eccentricity of stator 11 and rotor 6 is in the same sense as that of the rotors 4, 5, the rotor 6 absorbs the displacement of rotors 4, 5 and returns the fluid to the supply through port 21. The angular distances between the grooves in the stators are greater than those between any pair of adjacent vanes to provide a seal between the expansion and contraction chambers of each rotor.
