Abstract: 463,652. Cigarette-making machines. RUAU, F. F., BINGHAM, A., and MOLINS MACHINE CO., Ltd. Oct. 4, 1935, No. 27373. [Class 130] A machine for manufacturing mouthpiece cigarettes by uniting aligned adjacent stubs and cigarettes while both are moving axially and in which lengths of stub material are fed to a conveyer which feeds the stubs towards a line of axially moving cigarettes or between adjacent spaced cigarettes in the line, the stub feeding and conveying means being operative to move in paths transverse one to the other in the region where the stubs are transferred from the feeding means to the conveyer, is provided with control means between the feeding means and the conveyer and movable therebetween to position the stubs relatively to the conveyer. The stubs or mouthpieces may comprise empty tubes or tubes filled partly or wholly with filtering or flavouring material or tobacco and the tobacco may be different in kind from that in the body of the cigarette. Lengths of stub material sufficient for three double stubs are fed from a hopper to the flutes of a conveyer drum 3 where they are severed into three lengths by rotating knives. Guides 8 support the stubs as they approach the underside of the drum 3 and permit the outer stubs to fall away slightly while an inner guide 9 closer to the drum retains the centre stubs. The edges of the guide 9 are cam-shaped and engage the outer stubs to separate them axially from the central ones. A conveyer 10 passes the separated stubs to the flutes 15 of a further conveyer drum 16 where lateral guides 14 close the outer stubs axially on to the centre ones before guides 19, 18 similar to the guides 8, 9 again separate them. The inner and outer stubs roll down inclines 21, 22 respectively to control plates 20 reciprocated through levers 29 by cams 30 to arrest the stubs and permit one at a time to drop on to a conveyer disc 23. As each plate 20 is retracted, a projection 35 thereon engages the heel 34 of a positioning finger 32 adapted to deposit the falling stub on the stationary base plate 28 of the conveyer 23 which delivers the stubs to, or between separated lengths of cigarette rod. Specification 463,654 is referred to.

Title: Improvements in or relating to electric circuit breakers for alternating currents
IPC: H01H9/56
Filed: 1947-10-18
Abstract: 637,407. Automatic circuit breakers. KULKA, V. (Weiss, F.). Oct. 18, 1947, No. 27909. [Class 38 (v)] In a circuit-breaker for alternating currents, reinforcement of the contact pressure and the release of a free trip mechanism are obtained electro-dynamically during short-circuits, the contacts being opened as the current approaches or reaches zero. The moving contact 12 of the circuit-breaker is mounted on a spring strip 13, which is connected to the terminal 14 via strips 15, 6, a blowout coil 8, a strip 7, a blowout coil 9 and a plate 17. Hence when the circuit-breaker is closed, current flows in the same direction in the strips 6, 7, 13, and the contact-carrying strip 13 is attracted towards the strips 6, 7. The insulating base 1 on which the strips 6, 7 are fixed, is shaped so that when the contacts 10, 12 are closed, only a small clearance exists between the strip 13 and the strips 6, 7, contact between the strips being prevented by an insulating strip (not shown). When a short-circuit occurs the strip 13 is moved by the electro-dynamic forces, slightly towards the strips 6, 7, reinforcing the contact pressure and straightening the toggle 20, 21 of the operating mechanism. The toggle 20, 21 collapses under its own weight or by means of a spring, so that the contacts 10, 12 are held closed by the electro-dynamic forces only, and as the current approaches zero, the spring strip 13 is able to open the contacts 10, 12. After the circuit-breaker has opened, the toggle 20, 21 is reset as the operating handle 19 falls under its own weight to its lower off position. The circuit-breaker may be tripped under more normal overload conditions by thermal or electromagnetic means.
