Title: Improvements relating to voltage-current regulators
IPC: G05F1/32
Filed: 1954-07-13
Abstract: 782,684. Automatic voltage control systems; protective arrangements. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., WALKER, A. H. B., and KING, K. G. June 29, 1955 [July 13, 1954], No. 20451/54. Class 38 (4). [Also in Group XXXIX] In an automatic voltage control system of the kind in which the D.C. output voltage of a main rectifier is maintained constant by a selfsaturating transductor controlling the supply to the rectifier, the transductor being controlled by a D.C, winding energized by an output voltage detector, and in which the current output has an upper limit, the current limiting is effected by deriving the self-magnetizing current for the transductor from the rectified output for current transformer carrying the input A.C. current, this transformer being arranged to saturate at the upper current limit. The voltage detector is also arranged to have a limited range so that the normal control action does not override the limiter. In Fig. 1 only the A.C. windings 1 of the transductor are shown, and the self magnetizing current is obtained from current transformer 3 over rectifier 2. A variable resistor 4 enables the load on the transformer 3 and hence the point at which it saturates to be varied. In a modification, Fig. 2 (not shown) the variable resistor is replaced by a half-wave, rectifier poled so as to oppose the current flow, but normally made conducting by an auxiliary bias supply in series with a resistor. At the upper limit, the diode blocks 3 so effectively connects the bias supply and associated resistor as an additional burden on the current transformer to ensure saturation thereof.

Title: Improvements in carburettors
Inventor: AUGUST PAUL
IPC: F02M33/06
Filed: 1969-04-24
Abstract: 1,259,975. Spray carburetters. ATOX TRUST REG. April 24, 1969 [Dec. 21, 1968], No.20881/69. Heading F1B. An engine carburetter comprises a supplementary air inlet 9, Fig.1, located in the wall of the induction passage 1<SP>1</SP> at a position downstream of the idling orifice 4<SP>1</SP> and adjacent the region of turbulence created by the incoming idling fuel mixture. A projection 14 improves mixing of the air with fuel condensate c deposited on the induction passage wall. The inlet 9 may be a slot extending circumferentially around the induction passage over an arc of 40 degrees. The supplementary air may be pre-heated to improve cold starting and to rapidly increase the engine exhaust gas temperature to a value suitable for catalytic purification of the exhaust gas. The pre-heating is achieved in an inlet passage (12), Fig.2 (not shown), by heat from the exhaust gas, and by an electrical heating element (11) controlled automatically in accordance with the exhaust gas or engine temperature. Sufficient oxygen is available in the exhaust gas for catalytic purification but, if desired, additional air heated to above 200C. may be supplied to the catalyst at a rate dependent on the exhaust gas flow. The inlet 9 is made sufficiently large to supply the necessary air during idling since the throttle valve 2 is arranged to completely close the induction passage. The air inlet (31), Fig. 3 (not shown), is dimensioned to supply air equal to about 30% of the air-fuel mixture during slow-running and about 3 to 5% thereof during engine full load. The supplementary air and idling mixture flows can be controlled by screws (13) and 6 respectively. Moreover, when the throttle valve 2 is closed a switch 38 is closed to cause the idling fuel mixture to be controlled automatically by a solenoid-actuated valve 34 controlled by electronic means 35, 36 in accordance with engine speed. During engine over-run with the throttle valve 2 closed, the valve 34 is closed when the engine speed rises above 1800 to 2200 r.p.m., but is opened when the engine speed falls below 1500 to 1100 r.p.m. The supplementary air may be controlled by a valve (39) controlled by the electronic means 35, 36.

Title: Improvements in and relating to arrangements for preventing the formation of ice on aircraft
IPC: B64D15/02
Filed: 1938-07-14
Abstract: 505,873. Preventing formation of ice on aircraft. GROVES, W. W. (Junkers Flugzeug-und-Motorenwerke Akt.-Ges.) July 14, 1938, No. 20925. [Class 4] In means for preventing ice-formation on aircraft in which a gaseous or liquid heatcarrier is led into a chamber of large crosssection located inside the structure to be protected, e.g. a wing, strut, fin or rudder, and then passes along and in contact with the outer skin of the structure through one or more passages, the boundary walls of the chamber form at least part of the walls of the passages. In one form, Fig. 1, air is heated by passing it through aradiator 6 surrounding the exhaust pipe 3 and is led via a pipe 7 to chamber 8 extending along the entire wing span. The air then passes through an opening 9, formed along the front of the chamber, into passages 25 formed between the wing skin 10 and the walls 11 of the chamber, and finally escapes through openings in the rear part of the wing. The walls 11 may be formed by channel members, or . corrugated plates secured to the skin 10. In a second form, Fig. 5, which may also serve as a cooler for combustion air for a supercharged engine, air, heated, e.g. by passage through a blower or one stage of a multi-stage blower, enters a chamber 32 similar to the chamber 8 and passes via passages 33 into a second chamber 35 separated from the chamber 32 by a heat-insulating partition 36. The air then passes out via a pipe 37, e.g. to the carburetter or the next stage of the blower.

Filed: 1961-06-09
Abstract: 917,623. Hydraulic apparatus; valves. SOC. D'APPLICATIONS DES MACHINES MOTRICES. June 9, 1961 [June 21, 1960], No. 20950/61. Classes 69 (2) and 135. An hydraulic circuit comprises one or more hydraulic jacks or motors 1, each having a distributer 2, the distributers being arranged in parallel between a feed circuit 3 and a return circuit 4 and each distributer having a by-pass device 28, 29 which momentarily by-passes the distributer when the slide valve 23, 24 of the latter is moved a slight distance from its neutral position, and a decompression valve 10 arranged to control a circuit 17 by-passing the distributers. A pump 8 is connected by a non-return valve 9 to the feed circuit 3 which has a branch 37 leading to a chamber 27 in the distributer controlling the jack 1, the chamber 27 in the neutral position of the slide valve 23, 24 being closed. If all the distributers are in their neutral positions, the pressure in the feed circuit 3 builds up and acts in a chamber 16 to move the spool 12 of the decompression valve against a spring 13 so as to connect the outlet of the pump to a port 20 leading to the by-pass circuit 17. A throttle 21 and non-return valve 26 connect the circuit 17 to the tank 5 so that the pressure in the circuit 17 is relatively low and acts through a port 19 on the spool 12 to assist the pressure in chamber 16 hold the spool against the stop 14. When the spool of the distributer is initially moved by a handle 35, the chamber 27 is connected by an axial passage and one or other of two radial passages in the spool to one or other of two ports 28, 29 leading to the return circuit 4 so that the pressure in the feed circuit 3 drops and permits the spring 13 to move the spool 12 and disconnect the pump from the by-pass circuit 17 whereby, when the spool of the distributer is moved further to connect the feed circuit to one side or the other of the jack, the pressure can build up to its operative valve. In alternative embodiments, the by-pass device consists of a slide valve or rotary valve operatively connected to the distributer so as to by-pass the latter when its spool is initially moved from its neutral position and permit the decompression valve to move to its operative position.

Title: Electroluminescent lamps and methods
IPC: H05B33/20
Filed: 1950-08-24
Abstract: 731,345. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 24, 1950 [Sept. 30, 1949; Oct. 8, 1949; Jan. 28, 1950], No. 21013/50. Class 39 (1). The phosphor of an electroluminescent lamp is prepared by firing a mixture including zinc sulphide and zinc oxide and removing uncombined zinc oxide, e.g. by washing with a weakly acid solution of acetic acid or ammonium acetate, followed by filtering and rinsing in water. The lamp comprises a glass plate 1, with a transparent conducting layer 2, a thin layer 3 of phosphor impregnated dielectric material either alkaline or of low acidity, and a backing layer 4 of metal or conductive glass. A metal tab 5 connected to layer 2 is one terminal and the layer 4 the other. The conductive glass may be prepared by exposing heated glass to vapours of the chlorides of silicon, tin or titanium, and afterwards placing it in a reducing atmosphere. The layer 3 may be fine particles of copper activated zinc sulphide embedded in plasticized nitro-cellulose. If the backing layer 4 is of metal it is preferably reflecting, e.g. aluminium or chromium, and is best deposited in vacuum. The phosphor is applied in association with sodium bicarbonate, nitrocellulose, castor oil, ortho-nitrodiphenyl, dioctyl sebacate, chlorinated diphenyl, dioctyl phthalate, benzophenone, methyl acetyl ricinoleate, cellosolve ricinoleate, glycerol tri-acetoricinoleate and butyl acetate. Another composition is phosphor, castor wax, beef fat and castor oil suspended or dissolved in benzene and tetrahydrofuran. A highly effective phosphor is obtained by mixing 75 parts zinc sulphide, 25 parts zinc oxide, 1 part zinc chloride, 0.075 parts copper sulphide and 1 part lead sulphate. The copper is variable between 0.03 and 0.3 per cent and chloride 0.4-2.0 per cent but only 0.1 per cent if a fluoride is present. The amount of lead should be between “ and 5 per cent. The mixture is fired at 900-1250‹ C. in nitrogen and afterwards treated with acetic acid or ammonium acetate to increase brightness and resistivity, presumably by removing zinc oxide. Other ammonium salts are effective. Other activated zinc sulphide phosphors are suitable including those in which manganese is an activator. Other applications are described, e.g. Fig. 4, in which paired conductors 8, 9 are side-by-side and intermeshed in a space occupied by the electroluminescent material or intercoiled as in Fig. 2 (not shown). The assemblies are used as table lamps, panels, signs, clock faces and switch plates and in street lighting, giving illuminations of up to 20 foot-lamberts.
