Title: Circuit breaker with handle indicating means
IPC: H01H71/50
Filed: 1974-11-18
Abstract: 1452589 Automatic circuit breakers WESTINGHOUSE ELECTRIC CORP 18 Nov 1974 [28 Nov 1973] 49743/74 Heading H1N A circuit breaker, shown closed in Fig.1, cannot be reset after tripping if the contacts have failed to open, e.g. because of welding, and the position of the handle always gives a true indication of the position of the contacts. For normal operation a projection 33 on the handle 35 engages in a depression on a movable contact arm 29 and an over centre spring 43 maintains tension between the arm and a cradle member 41 which is pivoted on a post 42 at its one end and is latched at 73, 71 at its other end. The cradle member must be latched before the breaker can be closed but an overcurrent acting on a combined thermal and magnetic trip means 25 can release the latch to open the breaker automatically whereupon the handle 35 assumes the intermediate position of Fig.3 and the latch can then be reset by moving the handle towards and beyond the OFF position of Fig.2 (not shown). If the contacts are welded when the breaker is automatically tripped a projecting tab 81 on the cradle member 41 first strikes the contact arm 29 in an attempt to break the weld, failing which the tab lodges against a recess 85 on the arm 29 to block any further movement and following any attempt to relatch the mechanism, Fig.5 (not shown), merely results in the handle 35 restoring to the contacts closed position under the action of the spring 43, Fig.4 (not shown).

Abstract: 1453153 Incineration of explosive waste HERCULES Inc 26 Nov 1974 [27 Nov 1973] 51144/74 Heading F4B A process for the incineration of solid or liquid waste propellants and explosives in which, in the case of solids, the waste is fed into a hopper 10 and is moved through a metal detection and removal device 18 before being ground in the presence of water in the grinder 20 so that particles have an average maximum dimension less than 0À25 inch. In the case of liquid propellants or explosives an absorbent material such as sawdust is used to absorb the wastes and produce particles of less than 0À25 inch. Particles from either of the processes are washed into a mixer 22 where water is added to form an aqueous suspension which is pumped into the inlet end 30 of a rotary kiln 32. The temperature in the chamber 38 is maintained by a burner 44 at from 1200‹ to 2200‹ F., and the aqueous suspension is fed in at a rate so that water is evaporated as it contacts the hot kiln surface and this is followed by combustion of the suspension solids in the presence of air supplied from the line 36. Exhaust kiln gases may pass to a second incinerator 46 for further combustion, and are then drawn by the fan 60 through a precooler 54 and a wet scrubber 58 before exhausting to atmosphere.

Abstract: 1392866 Wiper drive system SWF - SPEZIALFABRIK FUR AUTOZUBEHOR GUSTAV RAU GmbH 16 Nov 1972 [23 Dec 1971] ] 52866/72 Heading A4F In a wiper drive system for vehicle head-lamps or windscreens, each of two wiper blades undergoes reciprocating linear motion over a respective headlamp or portion of windscreen, the drive being taken from a motor 10 which continuously rotates in one direction. A first blade is mounted on a push-rod 18 connected to a pin 17 which lies on a line AB joining axes 11, 13 and, therefore, moves reciprocatingly along the line AB as a chain 15 moves clockwise. A second loop 35 is mounted above loop 15, one side 33 being directly above line AB, the pin 17 being attached thereto. Thus a second wiper blade mounted on length 34, via a push-rod 20 on pin 19, is reciprocated in opposed phase to the first wiper. Pulleys 22, 24 are mounted on a guide rail which is provided with recesses to guide the pins 17, 19 and hence the push-rods 18,20.

Abstract: 1,204,897. Chromatography. SHIMAZO SEISAKUSHO Ltd. 27 Nov., 1967 [25 Nov., 1966; 1 Dec., 1966; 5 Dec., 1966; 30 May, 1967], No. 53959/67. Headings B1L and B1X. '[Also in Division H5] Components of a mixed fluid sample are introduced at 1 into a stream of carrier gas, e.g. helium, from 8, and pass therein to thermostatically regulated column 2a of conventional construction and composition, wherein the species present in the sample are separated into bands. These bands eventually pass to column 2b, which comprises similar conventional features, where the travelling bands are fixed. The fixed bands are eluted sharply and in high concentration, suitably after column 2b has been cooled, into spectrometer 5 for analysis by closing the flow of gas through column 2a, opening valve 10 so that carrier gas passes through resistance tube 9 and column 2b, and causing heater 7 which provides within the column enveloped by it a temperature gradient which decreases in the direction of flow of carrier gas to traverse the column 2b from the spectrometer outlet end towards the carrier gas inlet end. The separation of mixed fatty acid methyl esters is exemplified, and the process may be applied to liquid chromatography.

Title: Device for folding a strip of paper
IPC: B65H45/101
Filed: 1969-11-04
Abstract: 1,215,558. Folding paper. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 Nov., 1969 [7 Nov., 1968], No. 53989/69. Heading B8R. A device for zig-zag folding a strip of paper issuing from a machine recording information on the paper, comprises a feed mechanism for pulling the strip into the device, a control member responsive to the tension on the strip for controlling the feed mechanism, and an oscillatory folding member driven from the feed mechanism. As shown in Fig. 1, the feed mechanism consists of two coaxial motor-driven toothed wheels 1 engaging perforations in the strip, each wheel having a circumference equal to twice the length of strip between folds. The folding member is formed by two parallel plates 3, 4 and is pivoted at its upper end. A crank mechanism couples the folding member to the wheels 1 so as to cause oscillation of the member as the wheels rotate. The control member comprises a pivoted surface 7 spring-urged towards position M from position A. In position M, the surface 7 closes the switch of the driving motor, and in position A the switch is opened. The wheels 1 feed the strip at a slightly greater speed than that at which the strip is fed to the device. Starting with the surface 7 in position M with the strip bending outwardly as shown at B, the wheels 1 are driven so that the strip is fed forwardly and folded. Subsequently the surface 7 is moved downwardly due to the higher speed of the wheels 1 until the motor switch is opened whereupon the surface 7 rises again to position M and feeding and folding is resumed, these operations being repeated during the working of the device. In place of the wheels 1, endless toothed chains can be employed, the chains being adjustable laterally in accordance with the width of the strip.
