Title: Conveyor transfer unit
IPC: H02G1/12
Filed: 1971-05-17
Abstract: 1317862 Endless conveyers for wire terminal assemblies ARTOS ENG CO 17 May 1971 [15 June 1970] 15244/71 Heading B8A [Also in Division F2] As a pair of wires 12, 14 are cut and stripped by a mechanism 22 (Fig. 2) which is actuated by the movement in opposite directions of racks 32, 34, in engagement with a driving pinion 36, the wires are engaged by grippers 56a, 56b, on a conveyer chain 54. The latter carries the wires to terminal applicator machines 18 and 20. The grippers 56a, 56b, are synchronized with the cutting and stripping, by the action of a link 164 the end of which engages a yoke 170 rigid with the rack 34. This acts through linkage (Fig. 5) to pivot a cam 185, clockwise out of engagement of a tail 70 of one of the pair of grippers 56a, 56b, in position adjacent the mechanism 22. This releases the grippers so that their springs 62 (Fig. 9) can cause them to grip the wires. The link 164 is also connected to a linkage 132, 138, so as to operate a one-revolution clutch 78 (Figs. 6 and 7, not shown) (see Division F2) in the drive of the conveyer. Each pair of grippers 56a, 56b, are mounted so as to be laterally slidable (Fig. 10), relative to the direction of conveyance. This movement is controlled by a cam surface 74 (Fig. 3), so as to bring the wires correctly into position at the terminal applicators 18 and 20. Members 224a and 224b (Fig. 11), are urged together to hold the wires steady as the wire 14 is processed by the terminal applicator 18. These members are moved together by the operation of a rack 232 connected to a cam follower 234 which cooperates with a cam 238 on the conveyer sprocket shaft 52. The rack 232 drives gears 228a and 228b associated with the members 224a and 224b. Similar members 222a and 222b fulfil the same function for the wire 12 at the applicator 20. A member 242 (Figs. 1 and 3) is arranged to guide the terminal on the end of the processed wire 14 clear of the wire 12 as the latter is feed to the applicator 20. Rollers 250 (Fig. 9) cause the grippers 56a and 56b to release the wires 12 and 14 at the end of the conveyer.

Title: Improvements in or relating to the production of condensation products of acetylene
IPC: C07C209/60
Filed: 1940-12-20
Abstract: Polymerizable N - vinyl compounds are obtained by condensing acetylene with a body of the formula R-NH-X where R is an alkyl, aryl, acyl, aracyl or an ester radicle and X is a chlorine, bromine, iodine, nitrile, nitro, nitroaryl, or sulphonic radicle having in aqueous solution a pH less than 7.  Suitable compounds are N-chloracrylamides, N-cyanacrylamides, N-nitroacrylamides, N-chlorurethanes, N-cyanurethanes, N-nitrourethanes, N-acylsulphonamides, N-alkyl- or N-aryl-nitramines and N-(nitroaryl)amines.  Suitable condensing agents are preferably used such as mercuric salts, cadmium and zinc compounds and heteropolyacids; the agent may be produced in situ for instance by adding sulphuric acid to a reaction mixture containing a dissolved or suspended mercury salt.  The reaction may be effected in the presence or absence of solvents, such as ketones, ethylidene diacetate and other inert oxygen-containing solvents, or the liquid reaction products remaining in the residue after the lower-boiling unsaturated reaction products have been removed by distillation.  A polymerization inhibitor such as copper or a phenol may be present. Instead of employing distillation, unchanged starting material may be removed from the reaction products by aqueous alkali.  In an example acetylene is introduced into a mixture of monochlorurethane, mercuric acetate, and sulphuric acid at room temperature.  Vinyl chlorurethane is distilled from the product.  It polymerizes to a glass-clear product.

Abstract: 714,382. Dew point meters. ILLINOIS TESTING LABORATORIES, Inc. June 18, 1952 [June 22, 1951], No. 15399/52. Class 97(3) The instrument comprises an electrically isolated charge accumulating surface, means whereby a sample gas may be passed over said surface, means for introducing charged particles into the gas prior to passing over the surface, the particles including negatively charged particles which have an affinity for moisture deposit, means for cooling the gas in the vicinity of the surface, means for indicating the presence of a negative charge on the surface, and means for determining the temperature of the surface. As shown, the gas is led into a chamber 42 through an inlet 50 provided at 54 with an ionising substance, e.g., radium, and across an electrically insulated metal plate 43 to an outlet 51. Plate 43 is connected at 56 to a thermocouple and galvanometer and at 57 to an electrometer and is separated by a thin diaphragm 47 from a plate 30 which is cooled. Cooling is effected by the expansion of carbon dioxide as it leaves a capillary tube 28. The consequent cooling of the gas in chamber 42 results, when the dew point is reached, in the negative ions carrying a film of water and thus gravitating towards plate 43. This plate becomes charged and the dew point is ascertained by reading the meter connected to the thermocouple as soon as the electrometer is actuated.

Filed: 1953-06-09
Abstract: 732,829. Regulating. stopping. CLAYTON DEWANDRE CO., Ltd. May 25, 1954 [June 9, 1953], No. 15873/53. Classes 7(5) and 7(6). [Also in Group XXXI] An exhaust braking apparatus comprises an exhaust throttle valve 12 which is closed for braking by fluid pressure or vacuum operated means 6 controlled by the accelerator pedal 16 or like engine control device. As shown the exhaust throttle valve 12 is situated in a tubular section 5 inserted in the exhaust pipe and is operated by a compressed-air motor 6 comprising a spring-loaded piston 8 connected to the throttle valve operating arm 11, the compressed air being supplied to one side of the piston 8 from a reservoir through a pipe 14 under the control of a valve 15 actuated by a solenoid 17 the circuit of which includes a micro-switch 20 operated by the engine accellerator pedal 16. On release of the pedal 16 the switch 20 is closed and the solenoid 17 operates the valve 15 to supply compressed air to the cylinder 7, whereby the valve 12 is closed for engine braking. The compressed air may also be tapped off at 23 to actuate a second piston device 22 which shuts off the fuel supply in a diesel engine during braking or, in an engine supplied by a carburetter, shuts off the combustible mixture supply and opens a subsidiary air valve in the induction system. The motor 6 is carried by a plate 9 bolted between the throttle section 5 and the exhaust manifold 4 and the initial position of the piston 8 is determined by an adjustable stop 21. To assist re-opening of the valve 12 by the spring 19, the piston 8 may be constructed as a differential piston both sides of which are supplied with compressed air to close valve 12, the supply to the larger face of the piston being cut off when the pedal 16 is depressed so that the supply to the smaller face assists the spring 19 to open the valve 12. The exhaust braking apparatus may be rendered inoperative by the opening of a master switch 25 in the circuit of the solenoid 17 ; alternatively a cock may be provided to cut off the supply of compressed air to the valve 15. In modifications the system is adapted for operation by vacuum from a vacuum reservoir or by hydraulic fluid from an accumulator and the piston-type motor 6 may be replaced by a diaphragm type motor.
