Patent GB-514468-A (GB)
Title: Improvements in electric motor control systems
IPC: B60L9/04
Filed: 1938-05-04
Abstract: 514,468. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd., BINNEY, E.A., CORNER, H. S. POUND-, and SEDGFIELD, H. B. May 4, 1938, Nos. 13336/39, 13337/39, and 13338/39. Divided out of 514,433. [Class 38 (iii)] Traction or other motors 7, 7b, are connected to a source 2 in series with a machine 6 excited from an exciter 5 arranged to maintain in the motor armature circuit a predetermined current driving acceleration and regenerative braking as described in Specification 509,884. The biassing field winding 5b on the exciter is energized from a battery 8 by changing over a switch 15a. When the motors have been fully accelerated switches 12, 12a are closed to connect the motors in parallel to the supply and a switch 16 opened to disconnect the machine 6, operation of switches 13, 13a, connecting motor fields 7d, 7e, to be excited from the machine 6. Coaling with the motors in series may be effected by adjusting a rheostat 9 so that the current in the field winding 5b is reduced substantially to zero. Alternatively, a switch 14 is opened and switches 15, 15a, positioned as shown. The exciter 5 then controls the machine 6 to maintain the voltage in the motor circuit equal to that of the supply. No disturbance occurs when the switch 14 is reclosed. Similar coasting control is effective while the machine 6 is supplying the motor fields. The exciter 5 may be provided with a further field winding for connection across the switch 14. The further field winding on the exciter may be arranged for connection across the switch 16 which connects the motors 7, 7b and the machine 6 in series across the supply, and for connection across the switch 12a when the motors are in parallel across the supply. Thus coasting is effected in the one stage by opening the switch 16 and in the other by opening the switches 12, 12a, the switch controlling the connection of this additional winding across either the switch 16 of the switch 12a may be interlocked mechanically or electrically with the switches 15, 15a, to prevent simultaneous energization of the exciter field 5b and its additional field. Upon failure of the external supply a relay 18 causes opening of a switch 19 to insert resistance in series with the motor 1 driving the machines 5, 6. It may also effect opening of the switch 14 and positioning of the switches 15, 15a as shown. On restoration of the supply the coasting condition is obtained. Specifications 485,312, 509,041 and 509,239 also are referred to.

Title: An apparatus for testing a liquid
IPC: G01N21/77
Filed: 1962-04-06
Abstract: 991,298. Liquid analysis devices. H. J. HEYL, and H.J. HEYL, [trading as HEYL CHEMISCHE FABRIK KOMM.-GES. GEB.]. April 6, 1962 [April 6, 1961 ; Jan. 9, 1962], No. 13428/62. Heading B1X. An apparatus for colorimetrically testing liquids comprises a measuring chamber 4 having an inlet 3 and an outlet; an indicator supply chamber 8 above the measuring chamber ; a horizontal passageway 2 for a liquid to be tested extending between said chambers to the inlet 3 and an upright stem 7 carrying a valve body 5 co-operating with the outlet and extending through said chambers and said passageway and having an annular groove 23 therein which is located in the passageway when the outlet is closed (full lines) and in the supply chamber when the outlet is opened (broken lines). The numerals refer to the preferred embodiment shown in Fig. 1 in which the chambers and passageway are formed in a block and liquid to be analysed enters through duct 1 and passage 2 into the measuring chamber via an overflow arrangement 21, 22 leading to discharge opening 6. An adjustable throttle 16 is provided in the duct 1. The indicator is supplied from a bottle 10 mounted pivotally on valve 9 on a tube communicating with supply chamber 8. The stem 7 transports a predetermined quantity of reagent from chamber 8 into passage 2 by movement from the upper to the lower position. In the upper position the measuring chamber is rinsed with the liquid to be tested. A duct 14 provides for expulsion of air as the liquid rises in chamber 4. A chamber 24 with a sloping upper surface facilitates the removal of liquid from the annular groove 23 (which has a correspondingly sloped lower wall) when stem 7 is raised. Fig. 3 shows a valve assembly in which (a) in the position of valve 45 shown, supply line 37 communicates with duct 42 which is connected via filter 49 and pipe 35 to duct 1, Fig. 1, for supply of liquid to be tested, (b) by rotation through 90 degrees duct 1 is permitted to empty into discharge conduit 39 and (c) by further rotation through 90 degrees to connect supply line 37 directly to conduit 39. Discharge conduit 39 is connected to discharge duct 6, Fig. 1. It is stated that the metering stem 7 may be actuated automatically, e.g. by a motor driven cam mechanism. The apparatus can be used in connection with hardness tests for water. Such tests may involve the addition to the water of a stabilized solution of Eriochrome black-T containing an indifferent yellow dye (e.g. methyl orange) and an alkaline buffer, if desired with a complex-forming material, e.g. disodium ethylenediaminetetraacetate or of Brom Cresol green, methyl red and hydrochloric acid. In place of the dye a correspondingly coloured transparent wall portion may be used.

An injection nozzle 4 has a nozzle valve needle 6 which is movable to open position by pressure of the injected material on a frusto-conical portion 27 and has a cylindrical portion 16 which, during cooling of the moulding material, enters the nozzle orifice and pushes material remaining therein into the mould cavity 13. The valve needle 6 is biased toward closed position by a spring 10, the tension of which can be controlled by means of an adjusting nut 11 or an hydraulic cylinder (not shown). Air pockets 25 or other insulating means between the nozzle head and mould wall 15 divide the nozzle head into a heated zone 20 and a cooled zone 21. The nozzle and needle in the position shown complete the mould surface so that the moulded article is free of sprues and runners.

Abstract: 1356341 Utilizing energy of radio-active materials WILSON GREATBATCH Ltd 10 May 1971 [11 May 1970] 14010/71 Heading G6P In a cell for the direct conversion of nuclear to electrical energy, a radio-active, beta emitting, lithium hydride, formed by exposing lithium to tritium, is encased in layers of P- and N-type layers separated by a P-N junction interface. The cell is sealed in glass to prevent the release of tritium. Beta electrons from the hydride form hole-electron pairs in the P- and N- type layers and establishes a potential difference across the P-N interface. The magnitude of the potential difference decreases with time and a logarithmic rate due to the logarithmic decay characteristic of tritium. The cell may be applied to a cardiac pacemaker.
