Title: Improvements in or relating to plaster-board
IPC: D21J1/08
Filed: 1940-01-02
Abstract: 535,749. Compound sheet material; plasterboards. BRITISH PLASTER BOARD, Ltd., and ALLSOP, L. F. Jan. 2, 1940, No. 102. [Class 87 (i)] 1 [Also in Group VIII] Plaster-board has applied to one or both sides a layer of bitumen felt. As shown in Fig. 2 sections of plaster-board X are laid on a table D between rails E on which runs a carriage F driven by an electric motor H through a variable speed gear 1 and chain gearing J. Bituminized felt C from a roll passes over a guide roller N and pressure roller 0 and its free end is secured to the table. Gas burners P or electric heaters are located between rollers N, 0 and soften the bitumen. As the carriage travels along the table the felt is pressed on to the plaster board and after cooling it is cut between the sections. The pressure roller may be cooled by a felt pad kept saturated with water. Hot bitumen may be applied on the plaster-board in front of the pressure roller. Alternatively hot bitumen may be applied to the unheated felt or plaster-board. In a modification the heating and pressure means are stationary and the plaster-boards are fed on a conveyer belt. The bituminized sheet may be wider than the plaster-board and turned down over its edges. The bitumen felt may be applied to plaster-boards already in position on a building.

Title: Improvements in weft-replenishing mechanism for looms
IPC: D03D45/20
Filed: 1949-01-05
Abstract: 661,751. Automatic cop changing in looms. MACKIE & SONS, Ltd., J., and PRINGLE, A. Feb. 13, 1950 [Jan. 5, 1949], No. 328/49. Class 142(iii). When depletion of a solid cop is detected, a hook controlled by the cop feeler, or forming-part of it, extracts the remnant of the cop from the shuttle; on the next pick, weft is drawn from the cop remnant by the shuttle (which remains threaded) until it is halfway across the loom, when the weft is cut, the end left trailing from the shuttle being sufficient to complete the pick. A fresh cop is inserted into the shuttle at the opposite end of the loom. Cop feeler, Fig. 2. A feeler 23 is normally pushed forward by the cop at beat up but remains in the position shown when the cop collapses; the shuttle then strikes a screw 49, thereby releasing a latch 43 from a tooth 29 on a hook 6 pivoted on the feeler; the hook is swung into the end of the cop by a spring 39 acting through toothed gearing 33, 31. As the slay recedes, leaving the cop remnant on the hook, a striker on the slay engages a dog 38 to return the mechanism to the position shown. In another form, a hook acts as the feeler and, when it penetrates a depleted cop, is turned slightly by the shuttle striking a lateral projection on the feeler, whereupon a spring swings the feeler so that the hook takes hold of the cop. Cutting weft, Fig. 4. When the cop extractor operates, a hook 55 is lowered into the path of a finger 64 so that as the slay recedes a scissor blade 61 is raised and held by a latch 66 engaging a tooth 69; the yarn running from the extracted cop to the shuttle passes between the blade 61 and a fixed blade 59 until, as the slay continues its rearward movement, a striker 70 encounters a stop 72, thereby tripping the latch, whereupon the weft is cut. In another construction, the weft is guided by a hook which is displaced by a striker (similar to the striker 70) to press the weft against a single blade fixed on the slay. Controlling cop inserter. When the scissors, Fig. 4, are cocked, a cable 78 raises a striker 80, Fig. 6, into line with a dog 88 on the cop inserting hammer. As the slay beats up and operates the hammer, the dog swings to the position shown in chain line, thereby depressing the striker 80 sufficiently for over-centre action of a spring 84 to return it to its inactive position. In another construction, Fig. 9, an arm 131 lifts a dog 139 into the path of a striker 140, in which position it is held by a spring-loaded latch 133; immediately before the striker 140 operates the dog, it pushes the latch forward, so that the arm 131 drops down a slot 132 to allow the dog 139 to fall to its inactive position after the transfer hammer has been operated. Shuttles, Fig. 2. The shuttle has an opening in the front for entry of the feeler and extraction of the cop end, and a steel plate 50 for striking the screw 49.

Title: Improvements in or relating to control systems for engines
IPC: F02K3/00
Filed: 1950-01-05
Abstract: 714,052. Automatic control systems for gas turbines. BENDIX AVIATION CORPORATION. Jan. 5, 1950, No. 339/50. Class 38(4) The speed and combustion chamber temperature of an aircraft gas turbine are automatically maintained at valves preselected by means of a single control lever. As shown, the variable-stroke fuel pump 59 is adjusted in accordance with the difference between the voltage outputs of the manually adjustable servo transmitter 19 and the tachometer generator 31, the magnitude of the voltage of which is proportional to the engine speed. The propeller pitch is adjusted by mechanism 120 in accordance with the unbalance between the outposts of manually adjustable servo transmitter 21 and the temperature sensitive resistance bridges 65, 67. The latter are positioned at a high temperature point of the combustion chamber and measure respectively the temperature and rate of change of temperature of the chamber. An alteration in chamber temperature from the datum set by 21 produces an alteration of propeller pitch and hence of engine speed which, through generator 31 adjusts the fuel supply to correct the temperature charge. The maximum power taken from the engine is limited by the cam device 125 which is adapted to adjust the output from 21 as the control handle 1 approaches the maximum setting. The maximum power limit is varied in accordance with the ambient pressure and temperature by the bellows 135. In an alternative form the fuel pump and propeller pitch control mechanisms are transposed. Specifications 669,827, [Group XXXVII], 714,051 and 714,140, [Group XXVI], are referred to.

The adjustment of the blocks is made by screws 7 which pass freely through one block and threadedly engage the other. The upper part 2 of the sinker head comprises two components 1a, 1b and screws 20 are provided in the upper component 1a at various positions in its length and are adjusted to bear down on the lower component 1b to ensure that the midportions of the lower component are correctly positioned in respect of the sinkers.
