Patent GB-1304273-A (GB)
IPC: G05D23/22
Filed: 1970-03-09
Abstract: 1304273 Automatic control of temperature WINDMÍLLER & HÍLSCHER 9 March 1970 [21 March 1969] 11158/70 Heading G3R In a cascade regulator arrangement for controlling the temperature of an extruder 1, the respective datum temperature levels of a plurality of sequence controllers R(--) each controlling a respective coil for heating a respective portion of the extruder wall, are modified by the output of a guide controller including a bridge 3. The guide controller has a potentiometer 5 on which a desired temperature value XK(F) for a plastics mass being extruded, is pre-set. A thermo-couple 2 senses the actual temperature X(F) of the plastics mass. The thermo-couple voltage is added across an output resistor R4 of an amplifier TrV(F) to a feedback voltage derived from the output voltage Y(F+NG) of the guide controller amplifier 6 fed into the amplifier TrV(F). The value Y(F+NG) is significant of the difference between the desired and actual temperatures of the plastics mass, the zero level of this value being determined by a bias source NG. A further feedback loop via R7 C8 provides an integration component. Thermo-couples such as 11 sense the wall temperature at intervals along the extruder duct and their respective outputs X(1--) are algerbraically added to the guide control value voltage Y(F+NG) at a respective amplifier TrV(1---). The guide voltage polarity opposes the polarity of the thermo-couples 11 voltages. Thereby the outputs of amplifiers 14 of the sequence controllers are made to follow the output from the guide controller irrespective of their pre-set wall temperature values XK(1---). The amplifiers 14 outputs energize respective heating coils 9 to raise the wall temperature until the difference output from the guide controller becomes zero when the temperature of the plastics mass reaches the desired value. The amplification factors of the amplifiers 14 are individually selectable and determine the proportional characteristics of the sequence controllers R(1---). The cascade regulator may have PI or PID characteristics. A meter connected to the guide controller output gives an indication V(F+NG) which is a measure of the quality of the control, the less the indication departs from zero the better the control.

IPC: F42B19/20
Filed: 1917-08-03
Abstract: 128,608. Westinghouse Machine Co., (Assignees of Kasley, A. T.). Aug. 11, 1916, [Convention date]. Caustic - soda a n d l i k e boilers.-Relates to motive fluid generators for torpedoes and submarine vessels of the kind in which the motive fluid is generated by the chemical reaction of a liquid on a metal, for example by the action of caustic soda solution on metallic aluminium. According to the invention, the liquid is forced from a reservoir 23 into a generator 10 containing the metal by means of a pump 25 driven by the propelling engine 12. The inlet piping 16, 21 is perforated and extends to all parts of the generator to prevent localisation of thereaction. The mouth of the outlet pipe 20, 15 is protected by a gauze 18 to prevent solid particles being carried away with the gases generated. A separator 11 and a regulator 13 are interposed between the generator and the engine. The engine is started by firing an explosive cartridge at 103 in the chamber 39 of the separator. The pressure of the explosion gases starts the engine directly cr forces a small quantity of caustic sod a solution from the chamber 39 into the generator, and the engine is started by the gases thus produced. The caustic soda solution is loaded into the chamber 39 through the pipe 31, which is then closed by a cap 53. In a torpedo, the cartridge is fired by the mechanism which starts the steering-gyroscope at the moment of launching. The Specification as open to inspection under Sect. 91 (3) (a) describes also (1) the generation of motive fluids by the action of water on sodium or calcium dilute acid on sodium bicarbonate, and water and kerosene on hot copper oxide, (2) a relief valve 100, Fig. 1, on the conduit between the pump and the generator, - and (3) a drain cock 105, Fig. 2, for clearing the 'generator of liquid when the regulating valve 13 closes at the end of a run, a cartridge being fired into the separator 11 at the same time that the cock is opened in order to force the liquid out. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for moulding and vulcanizing pneumatic tires
IPC: B29D30/06
Filed: 1941-09-10
Abstract: 554,858. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. Sept. 10, 1941, No. 11611. Convention date, Sept. 12, 1940. [Class 87 (ii)] A tyre vulcanizing press comprises a pair of relatively movable mould sections connected together for shaping a " pulley-band " tyre blank into tyre form and having an inflatable former therein, and mechanical means for removing the tyre from around the former. The said means may also discharge the tyre from the press. The means shown comprises two arms 62 connected together at the bottom by a rod 64 and fixed at their upper ends to a shaft 61 journalled in lugs 60 on the upper press head 16. When the press is closed and vulcanization is proceeding the arms are clear of the mould sections. When the press is ready to open, compressed air is admitted to a cylinder 67 secured to a lug 68 on the head 16, whereby a piston rod 66 is moved outwardly and, via an arm 65, rocks the arms 62 inwardly. As the upper mould section 13 rises the tyre 70 pulls out of the mould sections and rod 64 moves under the tread portion of the tyre. As the mould section continues to rise the tyre is pulled up by the rod 64 and pulled clear of the (now deflated) airbag 48. When the press is fully open the air is released from the cylinder 67, the arms 62 and rod 64 return to their outer position, and the tyre is released to fall on a guideway 71 down which it slides to be carried away by a conveyer 72. The upper press head 16 comprises two arms 25 each of which is pivoted to a roller 26 slidably mounted in a vertical slot 27 in a side plate 28. The roller 26 is pivoted to a link 29 which is pivoted at 30 to a lever 31 journalled on a stationary shaft 32. The lever 31 carries a roller 34 which rides in a cam slot 35 formed in the face of a large gear wheel 19 driven by an electric motor 24 via pinion 21. Parallel side links 18 are pivoted at 18<SP>1</SP> to the gear wheel 19 and at 17 to the press head 16. The airbag 48 is secured at its top to the piston rod 43 of a compressed air cylinder 38 and at its base to the lower stationary mould section 10. Operation :-The press being fully open, as in Fig. 6, the airbag evacuated of air and the piston rod 43 in its uppermost position, the pulley-band 55 is placed over the airbag as shown. The motor 24 is then operated to turn the wheel 19 counter-clockwise, whereby the links 18 pull the head 16, rocking it about the (stationary) roller 26 as indicated by the broken lines A, B ; during this rocking movement the roller 34 rides in a circumferential part 35<SP>1</SP> of the cam slot 35. When the roller 34 enters an inwardly-extending part 36 of the cam slot 35 the lever 31 turns clockwise about its shaft 32, whereby the link 29 and roller 26 are pulled down and the press head 16 descends vertically as indicated by the broken lines C. During this closing movement, the piston rod 43 descends and the airbag is inflated with hot air by means of pipes 54.

Title: Improvements relating to railway signalling systems
IPC: B61L23/16
Filed: 1943-07-16
Abstract: 567,901. Railway signalling systems. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. N. July 16, 1943, No. 11631. [Class 105] In a coded track circuit railway signalling system, the timing of the current pulses and of the intervals is effected by two relays Z2, Z3, alternately connected, by a third relay Z1 which they control, into the anode circuit of a three-electrode valve V, the grid voltage of which is controlled by a timing device connected in by the relay Z2 or Z3 then in the anode circuit. As shown, the timing device comprises a condenser - resistance arrangement in which the time is marked off by the time required for a condenser to reach zero voltage from an initial voltage -E when charged from a source +E. Different timing is effected by the inclusion of resistances R75, R120, R180 under the control of relays DR, HR in accordance with ahead traffic conditions to give codes of 75, 120, 180 pulses per minute to the track circuit TC. The valve V is such as not to pass current until the grid voltage is zero. With the parts in the position shown, the condenser K2 is being quickly charged from +ve. through guard resistance GR over back contacts 5, 4 of relay Z1, while condenser K1 (previously charged in the negative sense through the guard resistance GR) is being slowly charged through resistance R75 from +ve. over back contacts of relays DR, HR and back contacts 3, 6 of relay Z1 and it will be seen that this applies a decreasing negative voltage to the grid of the valve V. When this voltage reaches zero, the relay Z2 is energized by the anode current over back contact 1 of relay Z1. Relay Z1 thereupon picks up over a front contact of relay Z2 and back contact of relay Z3 and sticks over its own front contact 2, thereby de-energizing relay Z2. Front contact 7 of relay Z1 now applies current to the track circuit while its front contacts 4, 5 now connect in the charged condenser K2 to the grid to initiate another timing whereby when the grid voltage reaches zero, the relay Z3 is energized, thereby to de-energize relay Z1 to end the current pulse to the track circuit, relay Z3 also becoming de-energized by the opening of front contact 1. Condenser K1 which was quickly charged over front contacts 6, 3 of relay Z1, is now included in the control to the grid of the valve V over the back contacts 6, 3 to time the " off " interval as described above. This cycle of actions continues so to apply a code of 75 pulses per minute. Similarly, codes of 120 and 180 pulses per minute are applied when the resistances R120, R180 are included in the timing circuit by the relays HR, DR. An arrangement is described in which only one condenser is used and the different timing of the pulses and of the intervals in a code is effected by short-circuiting part of the resistance, Fig. 2 (not shown).

Abstract: 559,540. Switch handles; air-break switches. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and YELLAND, H. F. Aug, 20, 1942, No. 11702. [Class 38 (v)] In order to prevent the movement of an operating lever from one extreme position to the other without a definite stop at an intermediate position, such as is necessary in isolating switches, a stop member is arranged to be rotated into the path of the lever at the desired point. Preferably this member is in the form of a collar 16 with aperture large enough to receive the lever 10, and rotatable in a suitable hole in the slotted plate 12 so that a cleft, admitting the lever, can be brought first so that the lever can enter, and, after entry, by rotation of the collar the cleft can be brought to allow the continued movement of the lever to the other extreme position. Arms 18 may be secured on the collar to prevent rotation when the lever is at either end of its path and lugs 20 on the collar and also, though not shown, at either end of the path may permit padlocking of the lever in one position.
