Patent GB-305005-A (GB)
Title: Improvements in or relating to advertising or like signs or devices
IPC: G09F13/14
Filed: 1928-05-14
Abstract: 305,005. Frenkel, G. May 14, 1928. Divided on 301,279. Drawings to Specification. Signs.-Daylight and night signs are formed of tubes of transparent material, the walls of the tubes forming stencils with reflecting surfaces surrounding the characters. A plain daylight-admission opening is left at the upper portion of the tube. The tube may be round, polygonal, or partly curvilinear in cross-section and when of glass may be formed by blowing or pressing. The sign characters may be formed during the blowing operation or may be etched, sand-blasted or otherwise abraded on the finished tube. The tube may be thinner at the letter-bearing parts. The tube may be made with two opposed stencils, the inner walls in this case forming mutually reflecting surfaces. The glass may be undulating, or patterned: for example muffled or cathedral glass. Metal end caps may be fitted to the tubes which carry suspension appliances and means for artificial illuminations. The mirrors may be formed on the tubes by treating the non-reflecting portions through stencils with a substance which prevents the silvering materials adhering, and then dipping the whole tube in a silvering bath, or alternatively the whole tube may be dipped, the characters covered with transparent lacquer and then the bordering covered by an opaque backing. The characters in some cases may be on a flexible band passing over rollers in front of a transparent part of the tube.

Abstract: 1,040,276. Locks. EATON YALE & TOWNE Inc. June 8, 1964 [July 30, 1963], No. 30098/63. Heading E2A. A pin tumbler lock comprises a body 10 with a bore 11 and a cylinder 12 mounted in the bore for angular movement therein, the body and cylinder having bores 15 which are aligned when the key is withdrawn and which hold spring loaded pins 17 for preventing angular movement of the cylinder until an appropriate key is inserted and is characterized by the provision of hardened steel members 19 located in further bores in the body and/or the cylinder near the exposed end in positions to protect some or all of the pins from the action of a drill applied to the exposed end of the lock. When the key is inserted in slot 14 the pins 18 are moved to positions flush with the outer face of the cylinder thereby pushing pins 17 wholly within the body 10 so as to allow the cylinder to be moved angularly by the key. The hardened steel members may be in the form of cylindrical plugs 19 mounted in additional bores parallel to the bores 15. An annular hardened steel ring 21 may also be interposed between a flange 13 on the cylinder and a shoulder in the bore 11. The plugs 19 may be replaced by a plurality of hardened steel balls 22, Fig. 4 (not shown), located in a diametrical bore in the cylinder. The pins may also be made of hardened steel or may be accommodated in hardened steel lines 23 in their respective bores.

Overhead sewing- machines.-A machine of the scale-pan type for seaming fur and gloves has six-motion looper 3 in a hollow looper carrier 1 supported at its front end by trunnions 4 and adjustable links 7 and at its rear end by an adjustable bearing 2. The links 7 supporting the trunnions 4 are secured on the shaft 23 by set screws 22 and the shaft 23 is held rigid laterally by collars which permit of axial adjust. ment. One of the links is provided with an extension 26 pivoted to the member 27 connected to the strap 28 of the eccentric 29, for rocking the looper, and imparting to it, its forward movement. The collar 36 on the carrier carries an extension working in the cam groove 37 to oscillate the looper about its axis. The bearing 2 in which the link 15 to which the end of the looper carrier 1 is pivoted, is carried on a stud 13 capable of horizontal and vertical adjustment by means of screws.

Abstract: 954,905. Overload safety devices for cranes. CLYDE CRANE & BOOTH Ltd. Sept. 6, 1960 [Sept. 7, 1959], No. 30447/59. Heading B8B. An overload prevention device comprises a cylinder 2 attached to a crane structure 3 and a piston 5 to which is connected the load, a predetermined fluid pressure, controlled by a device 12, being maintained below the piston by a compressor 8 and a reservoir 7. In operation the air pressure in the cylinder 2 and the reservoir 7, the volume of which may be variable, is raised until it equals the maximum permissible load of the crane, the compressor motor 9 being switched off by the pressure sensitive device 12 when this pressure is reached. When an overload occurs the piston 5 is drawn downwards from the top of the cylinder 3 and only moves back when the overload is removed. In a second embodiment liquid occupies the space in the cylinder and part of the reservoir, compressed air occupying the rest of the reservoir.

Abstract: 639,026. Saw-tooth generating circuits. HAZELTINE CORPORATION. Nov. 20, 1947, No. 30835. Convention date, Dec. 10, 1946. [Class 40 (vi)] In a saw-tooth wave generator in which a second energy storing device is charged through an impedance from a first energy storing device which has itself been charged through the impedance, the value of the impedance is reduced during the flyback period to permit a higher repetition frequency without a reduction of saw-tooth amplitude. When a negative synchronizing pulse is applied to the input terminals 14 of the circuit shown, valve 33 is rendered non-conducting and a capacitor 29 commences to charge from a previously charged large capacitor 20 to produce the scan portion of the wave. The charging circuit comprises resistor 23 in parallel with the impedance of valve 25 arranged as a cathode-follower and also a large resistor 30. Due to the cathode follower action the rising voltage across capacitor 29 is compensated by an equal voltage across resistor 23 and a linear rise is obtained, a diode 21 preventing capacitor 20 discharging into the H.T. source due to this rise. When the synchronizing signal ceases, capacitor 29 discharges rapidly through valve 33 and capacitor 20 recharges, but as the voltage at the cathode of valve 25 falls more slowly than that at the grid valve 25 is cut-off. The impedance of the charging path, however, remains small due to a valve 40 which is connected across the cathode resistor and which in the absence of the negative synchronizing pulse at its grid has a low impedance. The saw-tooth output is taken from terminals 15 connected across resistor 23 and is applied to the horizontal deflection plates of a cathode-ray tube, to the vertical deflection plates of which is applied a signal to be examined. Alternative capacitors 29<1>, 29<11> may be selected to alter the slope of the wavefront.

Abstract: 603,977. Balancing weight of guns. AKTIEBOLAGET BOFORS. Nov. 19, 1945, No. 31077. Convention date, Nov. 9, 1939. [Class 92 (i)] One or more members of the spring system for balancing a gun is so connected to the recoiling system of the gun barrel that the turning movement of the system decreases during recoil and increases during run-out, so that balance is effected in all positions. As shown, the gun is balanced by a spring 33 in a fixed cylinder 30 whose piston 34 is connected by a rope 36 to a cross-piece 38 which is movably mounted in a groove 39 of a lever 40 connected to the elevation system of the gun barrel. In firing, a rack 41 fixed to the recoiling system drives a gear-wheel 42 which, through bevel gearing, rotates a shaft 45 threaded in the crosspiece 38. By this means the cross-piece moves towards the gun trunnion 32 thus reducing the leverage of the spring 33, and at the same time, by reason of the disposition of the groove, the tension of the spring is also reduced. In modifications, 'Figs. 1 and 2 (not shown), the piston 34 of a pivotally-mounted cylinder is connected by a rod to the lever 40, the end of the rod sliding in a groove of lever 40 in one construction, and the pivot pin of the cylinder sliding in a groove of the mounting in the other construction. In another modification, Fig. 3 (not shown), the cylinder is fixed and is vertical and the rope 36 extends over a pulley and down to a member which recoils.
