Title: Improvements in the starting arrangements of internal combustion engines
IPC: F01L13/00
Filed: 1920-06-02
Abstract: 176,015. Tangyes, Ltd., and Robson, J. June 2, 1920. Starting.-In starting, by means of compressed air or gas, an engine in which ignition is effected by the heat of compression, additional air or gas under pressure is admitted separately to the cylinder or combustion chamber at such a time as to cause the charge to be compressed sufficiently to effect ignition. In a four-stroke engine in which liquid fuel is injected near the end of the compression stroke, the additional compressed air or gas is admitted when the main air-admission valve is at or near its closing position. In a twostroke engine, the additional compressed air or gas is admitted during or shortly after the entry of the scavenging-air into the cylinder. In the form shown in Fig. 1, the combustion chamber 1 is provided with air-admission and exhaust valves 2. 3 and with a starting and charging valve 6 normally closed by a spring 17. The casing 4 of the valve 6 is connected with a compressed-air supply by an inlet fitted with a check valve 8. The valves 6, 8 are actuated by means of projections 9, 10 on a shaft 11 connected by a lever 12 and link 13 to a lever 14 actuated by a cam 17 slidable on a shaft 20. At starting, the cam 17 is moved into the starting position by a lever 22 and the engine is set with the piston at the beginning of the power stroke. The lever 14 is moved to the left in Fig. 1 to open the valve 8 and admit compressed air, which opens the valve 6 and sets the engine in motion. The valve 8 is held open for a time by the cam projection 18 and is afterwards opened by the projection 19, to admit the additional charge of compressed air, when the main air valve 2 is at or near its closing position. After the engine has run for a time, the cam 17 is moved axially out of the active position. The cam projection 18 may be omitted, the lever 14 being held over by hand to open the valve 8 until the engine piston has effected half its outward stroke. When the engine is running at normal speed, it may be used to re-charge the reservoir for starting-air by putting the liquid-fuel pump out of operation and moving the lever 14 to the right in Fig. 1, when the projection 10 engages the stem of the valve 6 and opens the valve. The engine piston then compresses air and expels it through the valve 8 to the receiver. In a modification, the supplementary charge of compressed air is admitted by a separate valve actuated by the cam projection 19. In another form. the cam 17 actuates a valve in the compressed-air supply conduit leading to the valve 8, which is held open by a hand lever corresponding to the lever 14.

Title: Process for separating the components of alloys of copper and silver
IPC: C22B7/00
Filed: 1934-05-22
Abstract: Alloys containing 30 to 70 per cent of copper with the remainder consisting substantially of silver are treated with chlorine whereby, after the reaction has started, a fluid chloride melt is formed without further application of extraneous heat. The resulting chloride melt is poured into a solvent for cuprous chloride; when dilute hydrochloric acid and/or a sodium chloride solution is used, silver chloride is recovered as such, but by employing an excess of ammonia solution, the silver is liberated in metallic form and cupric chloride is formed and retained in solution.  To control the temperature of reaction, neutral salts such as sodium or calcium chloride, which are adapted to increase the solubility of cuprous chloride in the solvent used, may be incorporated in the reaction mixture.  When alloys are treated which contain small quantities of gold, platinum, &c., these may be recovered as a concentrate by stopping chlorination before the alloy is completely transformed. Any zinc or nickel present goes into solution with the copper and may be separated therefrom by known means.ALSO:A melt containing cuprous and silver chlorides, obtained by chlorinating alloys containing 30 to 70 per cent copper with the remainder consisting substantially of silver, is run into an excess of ammonia solution, the silver being precipitated in metallic form and cupric chloride being formed and retained in solution.  When chlorinating alloys containing small quantities of gold, platinum, &c., these may be recovered as a concentrate by stopping chlorination before the alloy is completely transformed.

Title: Improvements in and relating to electric drive motors of automatic washing machines and the like
IPC: H02K7/108
Filed: 1950-06-21
Abstract: 671,623. Control of A.C. motors; electromagnetic switches. BRITISH THOMSONHOUSTON CO., Ltd. June 21, 1950. [July 1, 1949] No. 15500/50. Classes 38 (iii) and 38 (v). A washing machine of the single basket wash and spin-dry type has a single motor for the washing and spin-dry operations, the motor having separate starting and running windings. The initiation of the drying period is effected by an electrically-operated valve which directs oil under pressure into mechanism for declutching an agitator mechanism and clutching the motor directly to the basket. Means are provided to prevent the motor from being overloaded, and its running winding being burnt out, when the motor takes up the drive for drying operation. A combined starting and valve-control relay has a coil 51, connected in series with the motor running winding 6, and a core 52 which co-operates with an armature 56 carried on leaf-spring 57. The armature 56 is biased by the spring and an adjusting screw to move away from the core. A contact 60 is carried on the armature and co-operates with a starting contact 61. A contact 62 is fixed directly to the armature and is adapted to engage a contact 63 provided on an arm 64 which is mounted on the base of the relay The contacts 62, 63, are in the overload protective circuit and are normally biased to a closed position.. When the motor is first energized the initial rush of current in the running winding circuit is sufficient to cause the electromagnet 51, 52, to attract the armature and close contacts 60, 61, so completing the circuit of the motor starting winding 5. When the motor reaches its operative speed the armature 56 moves to open contacts 60, 61, and de-energize the starting winding, the contacts 62, 63, re-closing. Contacts 65 are closed to initiate the spin-drying operation so energizing solenoid 41 of the electrically-operated valve. If the motor running winding takes excessive current the contacts 62, 63, open to de-energize coil 41 and decrease the oil-pressure applied to. the clutch mechanism which couples the motor to its load. The clutch slips, the motor speed increases, and the running winding current decreases until the return of the armature 56 causes re-energization of the coil 41 for full application of the clutch. In this manner the contacts 62, 63, are alternately opened and closed, without affecting the contacts 60, 61, until the inertia of the bracket has been overcome and the usual operating speed reached. Specification 625,324, [Group VIII], is referred to.
