Title: Improvements in or relating to annunciator systems
Inventor: DERR WILLARD A
IPC: H03K3/45
Filed: 1957-12-10
Abstract: 847,282. Magnetic amplifiers. WESTING- HOUSE ELECTRIC CORPORATION. Dec. 10, 1957, No. 38337/57. Class 40 (9). [Also in Group XXXVIII] An annunciator system comprises an OR circuit OR1 obtaining a plurality of inputs from static bistable magnetic amplifier circuits and having an output to operate an indicator AL (see Group XXXVIII). As disclosed, a warning contact AL1 applies a trigger pulse to the bistable circuit FF1 which comprises a full-wave resetting magnetic amplifier having a transformer 18 with centre-tapped secondaries to gate the set and reset half-cycles. The rectifiers 28, 29 in the reset circuit normally conduct but may be cut-off by the trigger pulse on 37, the resetting output across load 24 being fed back over diode 41 to hold the rectifiers 28, 29 cut-off. These rectifiers are unblocked by a positive voltage on terminal 47 (lamp reset buttons LR) to return the circuit to its initial state. The output from terminal 40 is supplied to the magnetic amplifier Al to light lamp L1 and also to a second bistable amplifier 2FF1 which acts as the reset circuit and is similar to FF1 save that to cut-off rectifiers 93, 94 in the reset circuit, positive voltages are necessary on both terminals 70, 71 to block both paths provided by the conductor 105. The output from FF1 is supplied to an AND-NOT gate AN1 together with the output from 2FF1. In this gate the circuit is of a half-wave resetting magnetic amplifier in which, if energization of the reset winding 116 is inhibited by a voltage on terminal 127 (cutting off reset diode 120) output through load winding 111 will not occur unless the second reset winding 117 is not energized from terminal 125. All the above is duplicated for each station (AL1) to be monitored, with lamp L1 acting as a station monitor and the signal from each NOT gate being fed to an OR gate OR1, the output of the latter energizing alarm AL. The alarm circuit is reset by button AR.

Title: Method of and apparatus for hot extruding metals
IPC: G05D23/27
Filed: 1972-08-17
Abstract: 1431884 Extrusion R CHADWICK and O E FLETCHER 15 Aug 1973 [17 Aug 1972] 38365/72 Addition to 1265671 Heading B3P [Also in Division G3] In a modification of the hot extrusion of metals process described and claimed in Specification 1,265,671, the read out of the radiation pyrometer which senses the temperature of the extrusion as it emerges from the die, is corrected by the read out of a temperature sensor, e.g. a theremocouple, or radiation pyrometer responsive to the temperature of a heated billet prior to its transfer into a container of the extrusion press, for instance at the exit of a furnace in which the billet is preheated. The read out from the said sensor is stored in a memory and is then applied to correct the pyrometer read out as soon as the extruded metal emerges from the die. As in the prior Specification the corrected read out from the pyrometer is used to control the speed of the extrusion and maintain the extruded metal temperature substantially at the optimum.

Abstract: 1,163,271. Vacuum switches. ENGLISH ELECTRIC CO. Ltd. 8 Aug., 1966 [6 Aug., 1965; 1 Sept., 1965; 9 Sept., 1965], Nos. 33781/65, 37302/65 and 38557/65. Heading H1N. The contacts 25 of a vacuum switch are mounted on the ends of stainless steel tubes 21 surrounded by copper helices 22 serving to connect the contacts 25 with external terminals 16, 18 and producing a radial magnetic field between the contacts which co-operates with the arc current to cause the arc to move around the contact surfaces. The coils 22 are each mounted between copper members 20, 23 and each contact is shaped to fit into a recess in the member 20 leaving an annular groove. The contacts 25 are centrally recessed so that the current paths from the coils to the annular contact surfaces 28 have radial components thus creating tangential fields which drive the arc out on to arc running flanges 27 of the contacts. The contacts may comprise a copperzirconium alloy body with an annular insert 28 of tungsten-copper-zirconium alloy (Fig. 2, not shown) or alternatively a single sintered tungsten member may have copper-zirconium alloy diffused into the body portion (as described in Specification 1,079,013). The coils 22 may be machined from a solid copper member (Figs. 4, 5, not shown) and have ceramic spacers (39) between the turns. In modifications the tangential magnetic fields are improved by making the connection (61) to the moving contact through the middle of a hollow fixed contact. Either or both fixed and moving contacts may carry the coils 22 (Figs. 6, 7, 8, respectively, not shown). The usual protective screens are mounted in the envelope. In an alternative arrangement (not shown) only the arcing electrodes are mounted on the stainless steel tubes with the coils and are both fixed while the load carrying contacts are mounted concentrically within the electrodes for relative movement. The fixed contact assembly may be spring- mounted to yield when engaged by the movable contact, reducing contact bounce and facilitating rapid separation. Reference has been directed by the Comptroller to Specification 1,078,863.

With a negative potential (logical "1") applied to all inputs A, B, C, all transistors 10-14 are cut-off, providing a zero voltage output (logical " 0 ") at 50, whilst if a zero potential is applied at one or more inputs, the affected transistor(s) conducts to provide a negative output at 50. The circuit thus performs the NAND function, and if the logic of the potentials is reversed (i.e. zero potential represents "1," negative potential represents "0") the circuit performs the NOR function.

Abstract: Polyurethane foams are prepared by establishing a quantity of polyol in a container having an outlet dispensing into the polyol, adjacent the outlet of the container a predetermined quantity of a catalyst(s) for promoting the production of polyurethane, discharging through the container outlet a predetermined quantity of the polyol/catalyst(s) mixture into a mixing means and whilst holding the mixture in the mixing means, dispensing a predetermined quantity of diisocyanate into the mixing means without it having come into contact with the polyol before entering the mixing means, mixing the ingredients and finally discharging the mixed materials.  The mixing may be commenced when all the ingredients have been dispensed or prior to the dispensing of the diisocyanate into the mixing means, and the mixing head may be pressurized during mixing.  The container referred to above may in fact be communicating liquid lines which lines carry the polyol and catalyst(s) respectively.  A fluorocarbon may be incorporated in the reaction mixture and suitably enters the mixing head admixed with the diisocyanate. The diisocyanate exemplified is toluene diisocyanate.ALSO:The mixing head of Specification 1,071,082 (see also (1), Figs 1 and 2, not shown) is supplied with polyurethane foam ingredients watered by reciprocating pumps operated by pneumatic actuators as at (4), (6), Fig. 1; catalysts from liner (14), (15) are first mixed with the polyol in line (7) and a fluorocarbon from line (18) with the diisocyanate in line (9).  Pressure air from line 29 is used to operate the pump actuators; pressurize the mixing head during operation; actuator the mixer let-down valve (41); form a solvent/air purging mixture, and move the solvent receiving cup (43).  A controller (44) operates solenoid/air valves sequentially, a mixing cycle comprising pumping ingredients in predetermined sequence; starting mixing motor; pressurizing mixing head; opening let-down valve and stopping motor; positioning cup (43) under mixer and purging with air/solvent blast while running mixing motor; and re-setting for next cycle.
