Title: Improvements in or relating to electric incandescent lamps
IPC: F21Y101/00
Filed: 1960-06-02
Abstract: 950,283. Electric incandescent lamps. K. SASSMANNSHAUSEN. June 2, 1960 [June 2, 1959; Nov. 11, 1959; April 22, 1960], No. 19562/60. Heading H1F. [Also in Division F4] The envelope of an incandescent lamp, the filament of which is supported by a mounting fused into the envelope and having one or more support members situated between the fused connection or connections and a plane perpendicular to the longitudinal axis of the envelope which intersects the filament at a part nearest to the fused connections, has at least one internal abutment surface nearer to the plane than to the fused connections, which faces away from the dome of the envelope and against which the support members engage. The invention is especially applicable to lamps having an envelope the dome of which is formed as a lens. In one form, the filament 9, Fig. 1, is carried by lead-in wires 4, 5 which pass through a glass bead 8 and are bent over at 10, 11 so that their free ends bear on shoulders formed by a circumferential constriction 2 of the envelope 1. In another form, the support wires are held by a rod-shaped bead abutting against an annular shoulder formed in the envelope, the dome of which is formed as a plano-convex lens. In the form shown in Fig. 3, a concavo-convex lens 30 is connected to a cylindrical envelope 31 having V-shaped bends 32 on opposite sides. Two parallel V-shaped arms 33 are formed in the envelope wall extending from the bends 32 to receive a metal holder in the grooves between the arms and abutting against the bends 32, the holder being fused to a glass bead 39 through which the leads 35, 36 supporting the filament 40 pass. The dome of the envelope may also be in the form of a double convex lens, the outer surface of which may be hyperbolic in section.

Title: Improvements in or relating to electrical pulse handling circuits
Inventor: CARPENTER HENRY GEORGE
IPC: H03K5/02
Filed: 1950-08-04
Abstract: 693,116. Pulse circuits. ELLIOTT BROS. (LONDON), Ltd. Aug. 3, 1951 [Aug. 4, 1950], No. 19611/50. Class 40 (vi). The Figure shows a pulse amplifying circuit in which a pulse train applied to the input of a valve V1 is produced across a resistive load Rs via an output transformer Tp, Ts. The ratio of the impedance of the circuit driving the transformer to the value of the effective load at the output terminals is of the order of 10. For the duration of a positive input pulse the secondary winding Ts is loaded by resistor Rs through rectifier G2 the time constant of the transformer being sufficiently long to obviate serious distortion of the pulse shape. During the interval between input pulses the voltage across the output terminals swings negative, Fig. 4 (not shown), and rectifier G2 is cut off, thus disconnecting resistor Rs. A train of positive output pulses is thus produced across the output load Rs of which the mean ,D.C. remains substantially, constant.

Title: Improvements in and relating to the control of combustion-product engines
IPC: F02G3/00
Filed: 1933-07-11
Abstract: 405,196. Combustion-product engines. KINGSTON, J. R., and POWELL, W. H., Engineer-in-Chief's Department, G.P.O., London. July 11, 1933, No. 19637. [Class 7 (i).] In an engine of the type referred to in Specification 246692, [Class 7 (i), Combustion-product &c. engines], the speed is controlled by throttling the exhaust or inlet gases from or to the power cylinder and controlling the fuel supply to the combustion chamber. As shown, the exhaust valve 6 and the fuel pump 3 are actuated by cams 7, 8 driven from the crank-shaft 9, the lift of the exhaust valve and the stroke of the pump being simultaneously controlled by wedges 12, 13 pivotally mounted on a rock shaft 14. Alternatively, the control may be effected by the use of tapered cams or by a system of links and levers with a movable fulcrum, or the fuel supply may be controlled by a bye-pass valve between the pump and sprayer, operated simultaneously with the exhaust valve. The inlet valve 5 is of the unbalanced thimble type ; and a relief valve is fitted to the compressor cylinder discharge to prevent excessive pressure in the combustion chamber. In a modification in which a sleeve valve is used for inlet and exhaust, a throttle valve is used in the exhaust pipe or manifold and a relief valve is fitted in the cylinder head. In another form, the inlet gases are throttled by an adjustable sleeve surrounding an inlet valve of the thimble type.

Title: Improvements in or relating to belt shifters for stepped cone pulley drives
IPC: F16H7/22
Filed: 1944-10-12
Abstract: 586,776. Variable-speed gearing. INVESTA MACHINE TOOLS & ENGINEERING CO., Ltd. Oct. 12, 1944, No. 19732.. Convention date, Oct. 22, 1943. [Class 80 (ii)] A belt shifter for a stepped cone pulley drive comprises a slide D movable on a guide E and having pins H, H1 on which are pivoted guide arms F, G, having forks F1, G1, through which the belt passes. The forks operate on the belt at points where the belt in its travel approaches each stepped pulley. The guide arms each have a tail or projection G2, which bears against a stop K to prevent rotation in one direction while rotation in the other direction is controlled by a light spring J. The slide D has a pin C engaging a slot B1 in a lever B the pivot A1 of which carries an operating handle. In operation, when the slide D is moved, the arm F which is to move the belt from a step P2 to a smaller one P3 moves bodily with the slide, the other arm G pivoting about its pivot H1 and stressing the spring J. The belt, being thus slackened, is then moved from a step Q2 to a larger one Q3 by the arm G moving against the stop K under the action of the spring' J. The spring J may be replaced by separate springs for each arm and the operating handle may actuate a pointer to indicate the position of the belt. The guide E may be inclined to the axes of the two stepped pulleys.

Patent GB-627207-A (GB)
Title: Improvements in or relating to recoil operated small arms
IPC: F41A3/44
Filed: 1945-08-03
Abstract: 627,207. Smallarms. CHEVALLIER, A. L., and SOCHACZEWSKI, S. Aug. 3, 1945, No. 19940. [Class 119] A gun comprises a combined barrel 2 and breech frame 1, Fig. 1, mounted to recoil on a cradle 3, a breech bolt 13, Figs. 13 and 18, reciprocating in the frame, and a saddle 8, Fig. 2, on the front portion of the frame, the saddle having depending inclined arms 23 on each side to engage in corresponding recesses in slidable inertia panels 25, and being capable of upward movement to free the breech bolt, and downward movement to lock it. When a shot is fired the barrel and frame recoil a short distance compressing a spring 4 to which the panels 25 are connected, and causing, by the engagement of the parts 23, 24, the saddle to lift. In this movement lugs 21 on the saddle are freed from recesses in the breech frame and a control lug 19 is freed from a recess 20 in the breech bolt, thus permitting the bolt to recoil alone. The saddle is held in the raised position until the breech is closed firstly by a catch serving to hold the breech frame in its rear position and thereby lifting the saddle by the 23, 24 connection. This catch is released by the recoiling breech bolt, and the saddle is subsequently upheld by a spring-pressed bar 18, Fig. 2, mounted in the frame and having a lug 17 which, when the breech-block in recoiling has allowed the bar to move to the rear under the action of its spring, engages in the horizontal limb of an L-slot in the saddle. A pivoted handlever 54 is used to retract the barrel and frame, and a finger piece is provided at the rear end of a slide 41, Fig. 18, for retracting the breech bolt. The breech bolt has a bore 44 for the reception of the recoil spring, and a bore 46 housing the spring of an ejector and also a buffer 48, which is adapted to contact a lug on the stern post 7, Fig. 1, and thus to compress the spring violently to effect ejection. A third bore 42 houses a spring-controlled firing pin which is held in the safe position by one arm 67 of a lever when its other arm is allowed to rise by the lifting of the saddle; firing is thus prevented when the saddle is lifted.

Title: Improved method for jointing two members such as the ends of pipes
IPC: F16L13/14
Filed: 1956-06-28
Abstract: 825,766. Making bearings; jointing; stretching. OLSSON, C. F. April 15, 1957 [June 28, 1956], No. 20026/56. Classes 83 (2) and 83 (4). [Also in Groups XXVIII and XXXVI] A method of securing a sleeve to a member fitting in the sleeve comprises inserting the member into the sleeve and thereafter elongating the sleeve to deform it permanently and cause it to clamp on to the member. To make a water-tight joint between two pipes 1, 2 a mild steel sleeve 3 with flanged ends 4, 5 is fitted over the ends of the pipes and the flanges 4, 5 are placed in recesses 17, 13 formed in jaws 16, 12 of stretching means. The jaw 12 is fixed and formed on a jack body 7 while the jaw 16 is formed as an extension of a piston 14 slidable in a cylindrical part 8 of the jack 7. The cylinder 8 is connected by a passage 10 to a cylinder 9 of lesser diameter containing hydraulic fluid and a piston 18 which is moved longitudinally, to move the jaw 16, by the rotation of a screw 19. The sleeve 3 is thus stretched to cause it to clamp tightly on the tube ends. The sleeve may taper slightly from the centre and may have a lining 22 of ductile material. The sleeve may be thickened at the centre at 23, Fig. 5, and an internal ring 24 may be fitted to provide a stop for the tube ends. A sleeve 3 of soft lead alloy or brittle copper alloy and formed with a large end flange 4, Fig. 6, and small end flange 5 may be fitted over the armoured sheath 25 of an electric cable 26 and elongated to cause it to clamp on to the sheath 25 and form a gland, the flange 4 being drilled so that it may be bolted to a junction box. A further thin sleeve may be inserted under the sheath 25. The sleeve 3 may have internal rings or projections 27. A sleeve 3 may likewise be attached to a rod or spindle to act as a stop or bearing. For connecting insulated electric wires 28.the ends 29 are bared and inserted in a sleeve 3 which is then stretched to cause it to clamp on the wires. Rods or bus-bars may be likewise connected.

Title: Improvements in television receivers
IPC: H04N5/53
Filed: 1952-08-08
Abstract: 716,840. Electron-beam apparatus. ZENITH RADIO CORPORATION. Aug. 8,1952 [Aug. 18, 1951], No. 20069/52. Class 39(1) [Also in Groups XL(b) and XL(c)] A beam-deflecting valve used for automatic gaincontrol and synchronizing-signal separation in a television receiver comprises a linear cathode, 19 which is connected to earth, and an accelerating electrode not shown in the figure having an aperture which results in a planar beam of electrons passing between the deflecting plates 17 and 26, to which the received video signals are applied.' The valve also comprises an intercepting electrode 21 having apertures 22 and 23 and two anodes 24 and 25. When undeflected, the electron beam falls upon the electrode 21; however the operating potentials for the valve are so chosen that the application of the synchronizing-signal portions of the video signal to the deflection plate 17 causes part of the electron beam to pass through the apertures 22 and 23 on to the corresponding anodes 24 and 25. Anode 24, which receives the electron beam passing through aperture 22, is connected to the scanning generator of the receiver to supply separated synchronizing signals thereto. Gating signals derived from the fly-back of the scanning waveform developed by the scanning generator are applied to anode 25 which consequently is able to receive electrons passing through the aperture only during the fly-back intervals, that is, when the circuit is functioning correctly, during the application of the synchronizing pulses to the deflection plate 17. The A.G.C. voltage developed at the anode 25 is consequently unaffected by noise signals occurring between the synchronizing-signal intervals. The signal developed at anode 25 is fed back to control the gain in stages 2, 3 and 4 and thus the deflection of the electron beam by the synchronizing signals is stabilized so that the mean position of the beam coincides with the left-hand edge, Fig. 2, of the aperture 23. It will be seen that this aperture is displaced with respect to aperture 22 to ensure that the beam passes centrally through the aperture 22. To allow proper working of the system in regions of high signal strength the aperture 23 comprises an additional narrow slot as shown. When the signal is first received, the large amplitude synchronizing pulses may deflect the beam past the confines of the main portion of the slot 23 so that apart from the additional slot no A.G.C. voltage would be developed at anode 25 and the equilibrium condition would not be achieved. It is stated that the electrode 21 and anodes 24, 25 may be replaced by two anodes corresponding in size and shape to the apertures 22 and 23 followed by a further collecting electrode.
