IPC: F21L4/00
Filed: 1922-09-18
Abstract: 207,906. Hailwood, E. A. Sept. 18, 1922. Battery lamps. - In miners' lamps wherein the bulb and its protecting-glass are arranged to slide into a casing to prevent their fracture when struck, these members are arranged on the top of the battery casing so as to prevent damage by falling bodies. The bulb E and the glass G are mounted on a base G<1> arranged to slide into a sleeve H against the action of a spring S. Conductors R, R<1> depending from the base G<1> make sliding contact with the spring- pressed terminals T of the battery A.

Abstract: 433,577. Miners' safety lamps; wick burners. JONES, T. A., Sunderland Road Works, Felling-on-Tyne. Sept. 4, 1934, No. 25399. [Classes 75 (i) and 75 (iv)] A miner's safety lamp, adapted to be kept reasonably cool for handling purposes, comprises an inner shield m which is in contact only with a deflecting ring r, an outer bonnet n which is not in contact with the top of the lamp, and a central outlet p<1> above the gauze or gauzes for the escape of the whole or the major portion of the products of combustion. The shield m is secured at its lower end to the ring r which bears against the exterior of the outer gauze and is secured to lugs l<1> projecting upwardly from the bonnet ring l by means of rivets which pass through extension bushes q and also secure the outer bonnet n in position. The shield m may be formed with air inlet holes below the level of the top of a long glass chimney h, and the top of the inner or outer gauzes may be fitted with a sheet metal top to prevent downdraught. The outer bonnet n may be plain, or it may be corrugated vertically or horizontally, and it may be fitted at the top with a strengthening ring n<1>. The lower plate p provided with the central opening p<1> is connected by short riveted bushes s to a central plate t which is connected by similar bushes u to an upper plate v provided with a carrying handle. The bushes u may be associated with rivets or with screws and nuts which facilitate removal of the plate v. The lower end of the bonnet ring l bears against a heat insulating washer k which bears against the flange of the gauze ring. The long glass chimney h is out of contact with the gauzes and serves as a combined inner glass and combustion tube. It is flanged outwardly at its lower end and held in position on a safety air ring c by means of a screwed cover ring e and an asbestos washer g<2>. The vertical cylindrical wall of the ring c is drilled with small holes which will admit sufficient air for combustion but will not pass flame, and said wall is formed with a horizontal flange to receive a burner dome f which is heat insulated by means of upper and lower asbestos washers g, g<1>.

Title: Improvements in and relating to electric power supply systems
IPC: H04B1/16
Filed: 1954-09-01
Abstract: 756,810. Power supply systems depending upon the use of a number of sources. BENDIX AVIATION CORPORATION. Sept. 1, 1954 [Sept. 30, 1953], No. 25422/54. Drawings to Specification. Class 38 (4). A power pack for providing an A.C. output voltage when its input terminals are energized either from an A.C. source, or from any one of a number of different D.C. voltage sources, comprises a vibrator and associated tapped transformer for converting D.C. to A.C., and a number of relays connected across the input terminals of the pack, one relay being responsive only to A.C. and the others being responsive, respectively, to the different D.C. input voltages, these relays having different time delays to prevent their simultaneous operation when the higher voltage inputs are applied. An A.C. input causes. operation of the A.C. relay alone, operation of which directly connects the input and output terminals of the pack, opens the connection between the D.C. relays and the input terminals, and disconnects the output winding of the transformer from the output terminals of the pack. Application of D.C. voltage to the input terminals causes response of one or more of the D.C. relays which effect operation of the vibrator and selection of appropriate tappings on the primary of the transformer, the output winding of which is now connected to the output terminals of the pack over contacts of the unoperated A.C. relay.

Abstract: 230,749. McLellan, H. Oct. 28, 1924. Padlocks.-The bolt of a permutation lock or padlock is released by means carried by the combination elements which comprise a series of concentrically arranged and independently rotatable elements 16, 17, 18 disposed within a fixed ring 10 arranged in the casing 2. The elements have circumferential grooves 22, 27, 30, and the outer ones have holes 23, 28 through which balls 33, 34 can pass, the inner one having a hole 31 for a ball 35.

Patent GB-781827-A (GB)
Title: Improvements in or relating to the balancing of dynamically unbalanced bodies
IPC: G01M1/22
Filed: 1955-09-08
Abstract: 781,827. Electric measuring systems. GENERAL MOTORS CORPORATION. Sept. 8, 1955 [Sept. 24, 1954], No. 25735/55. Class 40 (1). In apparatus for determining the amount and angular location of unbalance of a rotating body, the location is found by manually adjusting the angular position of a pair of cams, which rotate in synchronism with the rotating body, relative to a fixed reference point until a synchronous commutator associated with one cam is operated in phase with the output from a vibration pick-up, and the amount of unbalance is determined by a self-balancing type amplitude comparison circuit connected to another synchronous commutator associated with the other cam, the two cams being 90 degrees out-ofphase. In the form shown, a crank-shaft 12 is rotated by a motor 16 and the outputs from vibration pick-ups 22, 24 are fed to identical circuits, of which only one is illustrated. The amplified output of pick-up 22 is applied to a transformer 42 having a centre-tapped secondary 46 connected through a movable switch arm 54 to a centre-zero D.C. motor 94. Switch arm 54 is operated so as to reverse the polarity of the voltage applied to meter 94 by a relay 56 which is periodically energized by closure of a switch 70, 72 in circuit with a battery 84, the switch being operated by a cam 66, mounted on the shaft of motor 16, and angularly adjustable relative to the motor shaft by a graduated knob 80 which is rotated until the switch arm 54 is opened and closed in quadrature with the output signal from vibration pick-up 22, as indicated by a null indication on meter 94. The reading of the graduated knob 80 which registers with a fixed pointer 96 then gives the angular location of the unbalance at the one end of the crank-shaft 12. A second cam 68 is displaced 90 degrees from cam 66 and operates a similar commutator 100 to which the output from pickup 22 is also applied. The commutator output is compared with the voltage across a potentiometer 140 and the amplified difference signal drives a servomotor 138 to adjust the potentiometer for balance, the angular displacement of the shaft 146 of servomotor 138 which is required for this purpose and is indicated by a scale and pointer 150, 152 being a measure of the amount of unbalance at the one end of the crank-shaft 12. Servomotor 138 also positions the drill stop setting element 134 of a balancecorrecting drilling device. When all readings have been taken, motor 16 is stopped and handwheel 20 is manually adjusted to position the part of the crankshaft where a balance correction has to be made, over the bit of the drilling device. Operations are now repeated for the other end of the shaft, vibrations at which are detected by pick-up 24.
