Title: Improvements relating to belting incorporating textile fabrics
Inventor: ARNETT MEYRICK
IPC: B65G15/32
Filed: 1958-05-19
Abstract: 903,946. Laminates. BTR. INDUSTRIES Ltd. May 15, 1959 [May 19, 1958], No. 16072/58. Class 140. [Also in Group IX] Belting such as conveyer belting is made by embedding in elastomeric material such as natural or synthetic rubber or polyvinyl chloride a fabric some warp and/or weft threads of which have a greater crimp than other such threads, the differences of crimp being produced by using in the warp and/or weft some threads having different shrinkage or stress-recovery characteristics from other threads and effecting such differential shrinkage or stress-recovery during or after weaving. Preferably continuous filament threads, e.g. of nylon or rayon, are used with staple threads, e.g. of nylon or cotton, in a warp in which all threads are equally tensioned during weaving or the continuous threads are subjected to higher tension, the staple threads in both cases finally having the greater crimp. Alternatively threads of different twist or different diameters may be used, in the latter case those having less stress recovery (and therefore being crimped) having up to four times the diameter of the non-crimped threads. Crimping during or after weaving may be effected by heating or steaming to shrink the continuous threads. A further method is to use as the non- crimp thread a yarn with a high-twist set with water-soluble size, the latter being washed out after weaving. After weaving treatment may be combined with the application of elastomeric material to produce belting. The fabric preferably comprises individual warp threads of each kind arranged, alternately, but other arrangements are possible. Specification 811,108 is referred to.

Abstract: 562,272. Electrically-tripped switches. ELECTRIC TRANSMISSION, Ltd., and DANNENBERG, K. Nov. 13,1942, No. 16099. [Class 38 (v)] In order to overcome the tendency for cartridge fuses of high current rating to rupture with light overloads, they are employed with an overload protection device, for example, a thermal relay, bimetal strip or coil, or a trip coil, rated and time-lagged so as to deal with such light overloads and obviate blowing of the fuse, and operation of each element is adapted to release a striker, thereby upsetting a trip gear common to both strikers. Specification 541,562 describes a suitable striker-provided, fusible element with a latch for preventing automatic resetting of the striker. In a polyphase arrangement, operation of either striker in any phase may trip all the phases. In Fig. 1, strikers 4, 6 associated with the fuse 1 and overload device 2, respectively, are adapted to rotate interconnected levers 10 about their pivots 11 and move a retaining cam 22 clear of a pin 21 on a spring-actuated rod 14 which closes trip contacts 23. In a modification, Fig. 2 (not shown), an auxiliary switch in the casing is operated by release of a rotary lever. In Fig. 3, the elements 1, 2 act on a trip bar 46 on a rotary shaft 48 provided with a control spring 53 and resetting handle 51.

Abstract: 672,497. Filling-nozzles; filling casks. TECALEMIT, Ltd., (Tecalemit Soc. Anon.). June 30, 1950, No. 16461/50. Classes 21 and 125(i) A filling nozzle for containers comprises a body 4 including a vacuum chamber 23 in which moves a piston 3 carrying an ejector 1, 2 which, when the container is filled creates the vacuum to move the piston upwardly to cause a spring loaded valve 17 to stop the flow. When a handoperated cock in a supply connection 22 is opened, high pressure liquid flows through peripheral ports 14 into a space 24 whence it flows through the ejector 1, 2 to the container without wetting the walls of the part 2 so that no vacuum is created in the chamber 23. Should wetting occur, however, air can reach the chamber 23 through ports 10, 26 and 25. When the liquid level reaches the ports 10,.the port 2 is wetted and a vacuum is created in chamber 23, whereupon the piston 3 rises to the position shown in Fig. 2. This upsets the liquid flow in chamber 24 and the pressure acts behind the valve 17 to apply it to the top of ejector 1. The pressure then drives the ejector down along with the valve 17 to seal off the liquid supply. Closure of the hand-operated cock allows the valve 17 to rise restoring the parts to the original positions.
