Patent GB-348612-A (GB)
Title: Improvements in protective systems
IPC: G08B17/103
Filed: 1929-11-05
Abstract: 348,612. Protective systems controlled by light-sensitive cells. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Breisky, J. V. ; 7505, Rosemary Street, Pittsburg, U.S.A.) Nov. 5, 1929, No. 33658. Convention date, Nov. 6, 1928. Void [Published under Sect. 91 of the Acts]. [Classes 47 (i) and 47 (ii).] In a system wherein a light-sensitive device is employed for indicating or combating abnormal conditions, such as the presence of smoke in a place to be protected, the varying current flowing through a light-sensitive cell in response to changes of light intensity is employed for biasing the grid of a thermionic tube. The output of the tube, which varies in accordance with the current through the cell, is employed for controlling three electromagnetic relays. One of these controls contacts in a work-circuit, whereby protective arrangements, such as fire-extinguishers, are brought into operation when abnormal, e.g. smoke, conditions occur. The other two relays control means for indicating upward or downward fluctuations of the normal working conditions of the circuit. As shown, a mains transformer 14, with two secondaries 17, 18, is employed with a rectifier 19. The secondary 18 is used for heating a light source 47 and the filament 29 of a thermionic tube 28. The grid 31 of the tube is biased from a resistance 23 in the rectifier circuit, and the circuit of the anode 33 includes electromagnets 38, 39, 41 and an indicating instrument 42. A light-sensitive cell 43, which is constantly illuminated by the lamp 47, is inserted in the return lead from the grid 31 to the centre tapping of the secondary 17. In use, the illumination of the cell 43 by the lamp 47 results in a certain current through the cell, a certain bias on the grid 31, and, in consequence, a certain current in the anode circuit, which current holds all the relays inoperative. Should the anode current fall or rise slightly owing to fluctuations in the normal working conditions in the system, the relay 38 or 39 becomes operative to close contacts in the circuit of an alarm bell 60. Should smoke be present in the protected area, the anode current rises sufficiently to energize the relay 41 and close contacts in current leads 51, 52. This results in the operation of an electromagnet 54 which opens the valve 59 of a cylinder 58 of fire-extinguishing gas. As illustrated, the lamp 47 and cell 43 are arranged above a work-table 49 on which smoke conditions may occur. The system may be employed for giving notice of a break in the web in the manufacture of paper.

Abstract: 988,694. Cutting rubber. DUNLOP RUBBER CO. Ltd. Sept. 22, 1961 [Oct. 5, 1960].. No. 34079/60. Heading B4B. [Also in Division B7] An apparatus for severing a length of rubber from a strip and supplying it to a tyre building former comprises a rotatable cutter 11, Fig. 1, having a helically disposed blade 14 coacting with a fixed blade 10, a guide channel 27 for feeding the strip tangentially to the cutter, and means to rotate the cutter. The strip is fed into the channel 27 by a knurled feed roller 41 over freely rotatable rollers 33-35 carried by side members 6, 7 of a frame 1 movable about a pivot 2 by a pneumatically operated rod 3. A sprocket wheel 44, rotatable in each direction by a chain connected at each of its ends to one of a pair of pneumatically operated piston rods controlled by a switch 69 actuated by a feeder roller 71, is drivably connected to the feed roller 41 through a ratchet 45 and to the cutter 11 through gearing 46, 49 and a ratchet 50. A pressure roller 72 on a bell-crank 73 is urged by a spring 78 into contact with the strip when the frame is in its lower position and moved out of contact therewith by the action of a pin 76 when the frame is raised. In operation, with the frame in its lower position, strip is fed by the roller 41 to a roller 29. The frame is then raised to release the pressure roller 72 and bring the roller 29 into contact with the tyre carcass on the former which is then rotated and draws the strip on to the carcass. When the leading edge of the strip contacts the roller 71 the switch 69 is operated to actuate one of the pneumatically operated piston rods to rotate the cutter which severs the required length of strip to form the tread. The former is then again rotated to draw the remaining length of tread strip on to the carcass. The frame is finally returned to its lower position and the other pneumatically operated piston rod is actuated to rotate the roller 41 and recommence the cycle. The roller 41 and the cutter 11 each make one complete revolution during each cycle of operations and are angularly located by spring-loaded stops 52 and 53 respectively. The sequence of operations may be carried out automatically after the inititation by an operator. The former may be rotated while the cutter is operating to obtain a diagonal cut.
