Filed: 1961-09-01
Abstract: 941,096. Control of D.C. motors. GENERAL MOTORS Ltd. Aug. 15, 1962 [Sept. 1, 1961], No. 31533/61. Drawings to Specification. Heading H2J. The bias on a transistor which is in circuit with a motor and a D.C. supply is adjustable by a variable resistance to change the motor armature voltage. The armature may be connected between a positive supply line and the transistor emitter, the resistance being connected to apply variable voltage to the base. A series motor has its field winding between the collector and the negative supply line, whilst, with a shunt motor, the collector is in parallel with the field winding. A compound motor has its series field winding between the collector and negative supply line or between the emitter and armature; the shunt field winding is between the positive supply line and collector or is connected directly between the supply lines. A resistance may be connected between the collector and negative supply line to protect the transistor from overload. A relay in series with the collector and series field winding short-circuits the emitter-collector circuit when the current reaches a predetermined value, to prevent overloading when the motor is stalled.

Title: Programmable control means
IPC: G05B19/12
Filed: 1974-10-02
Abstract: 1474382 Automatic control system F WARHURST 2 Oct 1974 [3 July 1973] 31683/73 Heading G3N A programmed controller provides control pulses in a repetitive time cycle that are used by an interposed contactor unit to control the switching off or on of an appliance. The pulses are of a short duration, leaving an interval between pulses for manual over-riding control of the contactor unit. In the embodiment shown, for controlling a plurality of heaters, the program is formed by markings e.g. adhesive tape on a drum or tape that is driven by motor M. For each heater control, the markings are detected by an electro-optical system 15, using photodiodes or phototransistors to produce an 'on' pulse to contactor unit 2. This pulse is turned off after a given time delay, determined by an RC circuit, but unit 2 remains latched "on" until the end of a marking is detected. Over-riding manual control e.g. by push buttons, thermostats or pressure gauges may be provided in circuit 30, as selected by switch 24. The system may also be used to control motors or solenoid operated valves. Details of the system e.g. of a programmed drum or circuit 30 are given in Figs. 2-6 (not shown).

[Also in Division F4] Apparatus for atomizing liquids, including slurries and suspensions, and for making snow by atomization of water includes a rotatable hub 12, Fig. 1, driven by an electric motor 18, fan blades 14 and openings 28 arranged in such a fashion as to produce a flowing film of liquid from the openings over both surfaces of the fan blades, when the blades are rotating, with a significant component of flow of the film towards the trailing edges of the fan blades to provide atomization off the trailing edges. Back flow of air from the blades 14a, Fig. 4, may be countered by the inclusion of a second set of blades 14b shorter than and axially displaced from the blades 14a. The inboard section of the leading edges of the longer blades, see 114a on Fig. 8, may be brought down to the same axial location as the corresponding edges of the shorter blades 114b at the place where the fluid is applied. Concentric sets of openings 128a and 128b may be used. Alternatively, the liquid may be delivered up through a hollow shaft into the base of a cup-like hub or fed on to the blades by gravity. The device will atomize 15 United States gallons of water per minute by use of a five horsepower motor to rotate the blades at 3500 r.p.m. The resultant water spray provides atomized droplets approximately 500 microns in diameter. Ice-free snow can be produced from eight or nine gallons of water per minute at a temperature of 35‹F, in air at 27‹F and 70% relative humidity.

Title: Improvements in or relating to methods of lining electrolytic cells for refining metals
IPC: C25C3/08
Filed: 1923-12-20
Abstract: 208,712. Aluminum Co. of America, (Assignees of Hoopes, W., Edwards, J. D., and Horsfield, B. T.). Dec. 21, 1922, [Convention date]. Aluminium, obtaining. - A cell for refining metals by electrolysis has a refractory insulating lining formed by establishing in the cell a bath of fused material suitable for use as an electrolyte and containing a refractory material, such as alumina, desired as a constituent of the lining, and depositing from the mixture a crust containing such material on the walls of the cell. The cell comprises a metal shell divided into two water-jacketed sections 13, 14 insulated from one another, the former being connected to a source of current. The section 13 is provided with a heat-insulating layer 23 and a bowl-shaped layer 24 of carbon. A conductor 26 is secured to the shell and plates 25 welded to the shell ensure good contact with the carbon layer. A number of upper carbon electrodes 29, secured to a conductor 31, are provided. When the cell is to be used for refining aluminium, the bath may be composed of a mixture of alumina and fluorides of aluminium, barium, sodium, strontium, calcium and magnesium. A suitable mixture comprises 9 parts by weight of aluminium fluoride. 9 parts by weight of bariuin fluoride, 7 parts by weight of sodium fluoride, and sufficient alumina to saturate the mixture. The cooling action of the circulating water in the jackets causes a crystalline crust, which is chiefly alumina, to form on the sides of the shell. During the operation of the cell for refining, the bath mixture will be situated between an upper layer of pure aluminium and a lower layer of an alloy containing. aluminium and the thickness of the lining 32 will always be increasing, due to oxygen entering the bath through the oxidation of sodium formed at the cathode. The crust may be broken away when it becomes too thick thus forming a convenient method of removing excess alumina from the bath. Specifications 208,710 and 208,711 are referred to.

IPC: F02K3/11
Filed: 1967-07-13
Abstract: 1,182,687. Gas turbine jet engines; ram jet engines. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 13, 1967 [July 28, 1966], No.32367/67. Heading F1J. The invention relates to a double flow jet propulsion engine comprising a gas turbine engine disposed in a central primary duct which is surrounded by an annular secondary duct. A combustion system is disposed in the secondary duct and a variable area nozzle is provided at the outlet of the secondary duct, the nozzle comprising angularly adjustable flaps pivotally mounted on the inner wall of the secondary duct. Means are provided for tapping off air from the secondary duct at a point upstream of the combustion system disposed therein, and for injecting this air downstream of the adjustable nozzle flaps in the turbulent region downstream thereof. The invention is shown applied in the case of a gas turbine bypass or ducted fan engine, the engine comprising an inner duct 1 in which are located compressor (not shown), combustion equipment 3 and turbine 4, the duct terminating in a propulsion nozzle 5. An outer, annular duct 2 surrounds the inner duct and receives air from the compressor or fan or from an intake diffuser, a combustion system 6 being provided in the duct, and the duct terminating in a variable area propulsion nozzle which is defined by a fixed outer wall and a series of angularly adjustable flaps 9 which are pivotally mounted at 9a at the downstream end of the inner wall of the annular duct. Air is tapped off from the outer duct at a point upstream of the combustion system 6, the air flowing through a duct 11 and being discharged into the turbulent region downstream of the nozzle 9. The air flowing through the duct 11 acts to cool parts such as the turbine casing 14 and the nozzle flap actuators 15, also accessories indicated at 13. In the case of an engine in which the outer duct is supplied directly from the intake, the outer duct thus constituting a ram jet engine, the gas turbine assembly may be shut down, the thrust being produced solely by the operation of the ram jet engine.
