Abstract: 399,121. Vehicle &c. lamps. RIVIER, L., Jouxtens, Mezery, Vaud, Switzerland. April 28, 1933, No. 12400. Convention date, May 13, 1932. Addition to 374,911. [Classes 39 (ii) and 75 (iv).] In a vehicle or like lamp in which a portion of the light emitted by a source is concentrated by a reflector to the focus of a parabolic reflector which projects a parallel beam, the said focus approximately coinciding with one edge of a screening member which is adapted to intercept those rays which would not pass through the said focus and which would be projected upwardly by the parabolic reflector, as described in the parent Specification, the first mentioned reflector is constituted by a portion of an electric lamp bulb having an ellipsoidal reflecting surface and a filament placed at one focus of the ellipsoid. In the form shown in Fig. 1, the front glass 2 of a paraboloidal reflector 1 carries an electric lamp bulb 4 having an ellipsoidal reflecting surface 6, the foci of which coincide respectively with the filaments 5 and the focus 8 of the reflector 1, the bulb also having a transparent portion 7 which is spherical about the focus 8 as centre, and a screen 13 is arranged with its upper edge coinciding with the focus 8. The screen 13 may be inclined or at right-angles to the common axis of the ellipsoid 6 and the paraboloid 1, it may be plane, stepped, curved, or made in two parts at right-angles to each other, and the intercepted rays may be absorbed or reflected back into the ellipsoid. The screen may be carried by a lever 12 pivoted to a support 10 which is adjustably mounted in a sleeve 9, and the lever may be held in an inoperativeposition by a spring and pulled into the operative position by means of an electromagnet 11. Alternatively, the transparent portion of the bulb may be convex with the screen and both foci of the ellipsoid located within the bulb, and the axis of the bulb may be arranged at rightangles to that of a part paraboloidal reflector. In the form shown in Fig. 3, a number of bulbs 18 are arranged with their axes at acute angles to that of a paraboloidal reflector 21 having its focus 20 coinciding with the centre of an adjustable opening in an absorbing diaphragm 23 and with the conical ends of a pair of cylindrical screens 22.

Patent GB-125126-A (GB)
IPC: F41A1/08
Abstract: 125,126. Armstrong, Whitworth, & Co., Sir W. G., Hadcock, A. G., and Forster, G. June 2, 1916. Ordnance design; chambers. - Relates to non- recoiling guns used on aircraft, from which simultaneously with a projectile., a compensating- mass is discharged rearwardly. According to the invention, two barrels are arranged co-axially, breech to breech, and mounted upon a connecting- frame, and between the barrels is provided a chamber of sufficient length to contain two projectiles and a propelling-charge. The chamber is co-axial with the barrels in the firing-position, but is moved out of alinement for loading. In the construction illustrated in Figs. '1 and 2, two barrels A, B are connected by a piece C which is open at the top and bottom to allow the chamber D to swing on pivots E. The joint F at each end of the chamber is covered by a hollow gas-check ring G, which may have a lining H as shown in Fig. 3, or may be formed in two parts as shown in Fig. 4. In either case, gas which escapes from the joints F forces the lips K on to the gun and chamber to prevent escape. The two rings G are free to slide, and are joined by bars L which are fixed to the left-hand ring, but slide on and off the other ring as the chamber moves out of alinement. The rings G are drawn off the joints F, and the chamber is swung out of alinement, by means of a hand-lever M or a foot-lever N pivoted at O. A toe P on the lever M or N engages a groove in one of the bars L to withdraw the rings during the first part of the stroke of the lever, and a roller Q on an arm attached to the lever engages a groove in the chamber D so that the continued movement of the lever M or N swings the chamber out of alinement with the barrels. The gun may be fired mechanically, electrically, or by friction. As shown, electric firing is adopted, safety contacts S being arranged on the actuating-lever and a bracket T on the gun. Several modifications are described and illustrated. In one, the chamber D is fast with one of the barrels, and this barrel swings on a pivot in the connecting-member C. In a second modification, the chambers, three in number, are arranged to rotate about a pivot above the line of the barrels, the chambers being brought successively into position for firing. In a third modification, two chambers are moved laterally in guides into and out of position for firing. In a fourth modification, five chambers are arranged after the manner of a revolver, and are brought successively into the firing position, the chambers being moved longitudinally away from one barrel before rotation, and the second barrel being simultaneously moved away from the chamber. The reverse movement brings the barrels and one chamber into close contact again.

Title: Improvements in or relating to knitting machines
Inventor: START ERNEST
IPC: D04B11/00
Filed: 1954-05-01
Abstract: 772,737. Knitting-machines. COTTON, Ltd., W. April 28, 1955 [May 1, 1954], No. 12700/54. Class 74 (2). An electrical circuit controlling the electric motor of a straight-bar machine, has switches 3, 4, 5 associated with the racking mechanism for the narrowing points or selvedge stops. Another switch 9 is associated with the narrowing frame 26 and is normally held open by the frame when it is in its raised inoperative position. Assuming that the narrowing points are correctly aligned with the needles, the switches 3, 4, 5 which are controlled by the indexing mechanism 10 through levers 12 are closed and upon operating a power rod to start the machine, switches 2 and 1 are closed in turn such that current flows from line A through switches 3, 4, 5, normally closed switches 6, 7, 8, and switches 2, 1. From the switch 1 the current passes through press-button stop and overload switch M to energize contactor coil K which causes contactor G to close to enable current to pass to the motor. Simultaneously, retaining switch HJ is closed to maintain the coil K energized and to retain the contactor G closed. the power rod being returned slightly to open switch 1. Prior to narrowing or selvedge stop adjustment the narrowing frame 26 is lowered, thereby closing switch 9 and retaining the circuit closed whilst the subsequent narrowing and selvedge stop adjustments are made during which time the switches 3, 4, 5 are momentarily opened. If, however, the narrowing mechanism or selvedge stops are incorrectly positioned, one or more of the switches 3, 4, 5 remains open such that upon the narrowing frame 26 returning to its raised inoperative position and opening its switch 9, the circuit becomes broken and the coil K de-energized. This action releases contactor G and breaks the supply to the motor such that the machine is stopped.

Title: Valve unit for containers of pressurized fluids
IPC: F16K31/40
Filed: 1954-05-03
Abstract: 760,427. Valves. BENDIX AVIATION CORPORATION. May 3,1954 [May 28, 1953], No. 12803/54. Class 135. A unitary tank filling and delivery valve device comprises a check valve 24, Fig. 2, in bore 19, through which the tank is filled with pressure fluid via bore 17, and a valve 52, Fig. 3, operable by tank pressure under the control of valve 76, for delivering the fluid from the tank to an outlet 47, via bore 45 communicating with bore 17. A spring-loaded valve plunger normally rests at 54 on a seat 50 and has slots 62 forming between a sealing ring 61 and the valve end 54 a chamber communicating with the conduit 17 and the tank, and a chamber 65 at its opposite end. The chambers normally communicate with each other through passages 66, 74, shuttle lift valve 76 and passages 67, 75. When solenoid 90 is energized the valve 76 is moved to close passages 66, 74 and open chamber 65 to atmosphere via passages 67, 75, 98 so that tank pressure acting on shoulder 53 removes the valve 54 from its seat 50. Excess tank pressure is relieved through passage 27, Fig. 2, by opening valve 36 against spring 38, but the force of the spring may be removed by the handle 42 so that valve 36 opens for draining.

Title: Improved safety device particularly for the servo-controls of aerodynes
Inventor: ERNST ADOLPHE OTTON GONTIER
IPC: B64C29/00
Filed: 1962-04-04
Abstract: 987,704. Aircraft servo-controls. SOC. NATIONALE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. April 4, 1962 [April 7, 1961], No. 13011/62. Headings B7G and B7W. An aircraft servo-control system comprises three servo systems, the power output stages of which are each coupled to a common driven member, means for comparing the performances of the three units, and switching means which normally allows all three units to operate together, and which by a single operation can disable a faulty unit and put a second unit in reserve, the third unit remaining operative, another single operation interchanging the functions of the second and third units. In Fig. 1, three hydraulic jacks 3a, 3b, 3c, are connected by a common piston rod 3d to the elevators. The jacks are supplied by pumps 5a, 5b, 5c, through cocks 7a, 7b, 7c and distributers 2a, 2b, 2c, controlled electrically by pilots' control movement sensors 1a, 1b, 1c. Pumps 5a and 5c are driven directly by the aircraft engines 9a and 9b respectively, the third pump being driven by both engines through a differential 10. Each jack has a by-pass 4 containing overload relief valves 4<SP>1</SP>, 4<SP>11</SP>, whereby a failed jack can be overridden by the other two jacks. Means are provided, Fig. 2 (not shown) for comparing the movements of the distributers 2a, 2b, 2c, and flowmeters 11 may be provided for comparison of the hydraulic parts of the servomotors. The comparison means indicates a fault by lighting the appropriate one of three lamps, whereupon the pilot presses the corresponding one of three buttons 16a, 16b, 16c, Fig. 3. These buttons, together with a switch 17, control the cocks 7a, 7b, 7c, electrically. With switch 17 in the normal position shown, pressing button 16a when jack 3a fails, for example, closes cocks 7a and 7c, jack 3b alone remaining operative. Changing over switch 17 opens cock 7c and closes cock 7b, so that jack 3c alone is operative. Equally, pressing button 16b or 16c renders the corresponding jack and one other jack inoperative, which other jack will replace the remaining operative jack when switch 17 is changed over. The appropriate switching actions may be performed automatically on detection of a fault.

Patent GB-131625-A (GB)
IPC: H01F5/00
Abstract: 131,625. Plaisant, G. May 29, 1918. Transformers. - An electro-magnetic fabric comprises solenoids, with or without iron cores, and conductors interlaced therewith in such a manner as to defect the magnetic lines of force to one side or the other. The fabric may be in the form of a cylinder, as shown in Fig. 4, and the solenoids b and interlacing conductors c may be excited with direct or alternating current. Instead of deflecting all the lines of force to one side of the fabric they may be deflected to one side in one half of the fabric and to the other side in the other half. In place of the iron cores, sheet-iron plates or cylinders suitably perforated may be used. In the application of the invention to transformers, the fabric A, Fig. 11, surrounds, or is surrounded by, a core d with a solenoid winding e. In a modification of the transformer, the inner and outer cores are subdivided as shown in Fig. L4, each individual core being provided with a separate winding and being connected with the corresponding core in the fabric. The transformer may be operated as a frequency changer by having the inner core d, Fig. 11, saturated and the outer core d unsaturated and connecting the solenoids on the cores d in series. In the subdivided core transformer, Fig. 14, the frequency may be multiplied by exciting each solenoid a' of the fabric with the current induced in the solenoids e', e<2>, immediately preceding it. The' transformer may be employed in systems of wireless or ordinary telegraphy.
