Patent GB-1527822-A (GB)
Title: Remote starting system for a combustion engine
IPC: F02D28/00
Filed: 1976-12-20
Abstract: 1527822 Remote starting systems for internal combustion engines J C BUCHER 20 Dec 1976 [23 Dec 1975] 52998/76 Heading H2H A system for starting a remote internal combustion engine comprises a control signal receiver, a circuit coupled to the receiver for initiating a starting operation in response to a control signal and for connecting a potential source B+ to a starter motor, and means for the momentary pumping of fuel into the engine prior to the starting operation. On receiving a signal from a radio or wire linked transmitter, contacts of a relay K2 in the receiver are closed so that a transistor Q10 is switched on. Transistors Q5, Q11 are latched on thereby switching on a transistor Q4 to energize a relay K1 and close its contacts. Power is therefore supplied to the ignition system and other accessories of the vehicle. The conduction of the transistor Q10 switches on a transistor Q7 which in turn switches on a transistor Q14 to energize a device GAS SOL. This device causes the momentary pumping of fuel into the engine and holds open the carburettor butterfly valve. This pumping of fuel may be repeated by repeated closing of the relay K2 at intervals of less than 5 sees. When the relay is released, a circuit including a unijunction transistor U1 times a period of 5 sees. at the end of which the transistor U1 switches on a transistor Q6 and a transistor Q12 to energize the starter motor solenoid START SOL. After the engine has started, the devices GAS SOL and START SOL are de-energized by detecting the alternator output which switches on a transistor Q1 thereby switching off the transistor U1. The throttle then closes to an idling position to prevent overspeeding of the engine. If the engine stalls the five second timing period is repeated with re-energization of the devices START SOL and GAS SOL. About four minutes after the starting system is energized a unijunction transistor U2 becomes conductive thereby switching on transistors Q7, Q14 to provide the momentary pumping of fuel into the engine. After the engine has been idling for twelve minutes, a unijunction transistor U3 becomes conductive and switches on a transistor Q8 thereby switching off transistors Q5, Q11, Q4 so that the relay Kl is de-energized and the ignition is switched off. A unijunction transistor U4 becomes conductive after a period of ten seconds to disable the system if the cranking of the engine has not started the engine within this period of time. Similarly, shut down of the system occurs if the device GAS SOL is operated for more than 10 sees., for example due to short circuiting of the transistor Q14. If the vehicle is tampered with, such as by operation of the brake pedal or the opening of a door, the starting system is shut down. The remote starting system may be over ridden by a manual start switch K3. The starting system may be used in a spark ignition engine or a diesel engine having glow plugs, in which case heating of the glow plugs begins as soon as the relay K1 is closed.

Air is supplied via flexible conduit 23 and passages 78, 66 to air chamber 17, which, by means of diaphragm 13, pumps liquid from chamber 16 to outlet conduit 25 and actuates connecting rod 21 to exhaust air from chamber 19 and draw liquid into chamber 18 via conduit 28. The connecting rod 21 has attached to it an actuating member comprising a yokeshaped telescoping link 85 with a roller bearing  86 riding in a groove 87 in the member 76. The arrangement is such that when the rod 21 has moved far enough to the left the telescoping link passes its over-centre position and then, by means of roller bearing 86 in groove 87, causes the member 76 to slide to the right. This supplies air to chamber 19 via port 75, the air in chamber 17 being exhausted to atmosphere via port 74 and opening 94, causing connecting rod 21 to move to the right. When rod 21 is far enough to the right the over-centre action causes member 76 to slide leftwards to repeat the process.
Patent GB-532064-A (GB)
Abstract: 532,064. Air - conditioning in buildings. CARRIER ENGINEERING CO., Ltd., and SAINTY, C. L. Aug. 15, 1939, No. 23551. [Class 137] Uniform temperature is maintained in different zones of a building or ships by controlling-means utilizing solar heat which reaches zones in the sun. A narrow flat vertical tank 2 is exposed to solar heat and is connected in a thermocircuit including gilled pipes 4, valve 9, and pipe 7 containing a thermostat 8. The system contains water, and the temperature reached in the tube 7 depends on the solar heating and on the restriction imposed, by the valve 9. When a pre-determined temperature is reached, the thermostat operates dampers in the air-conditioning apparatus to vary the supply of cooling air to the zone. The cooling effect is dependent on the volume of air passing over the tube 4 and this may be adjusted by louvres 10 or 11. The thermostat may be arranged on the roof so that the cooling of the water in the circuit is influenced by external temperature. The thermostat may control baffles 14 in branches 15 of a main supply 16 of conditioned air to zones 17. The zones may be part of a floor space which may or may not be partitioned off. Part of the used air may be mixed with fresh air. The duct 16 may be a central ceiling duct, a plurality of baffles such as 14 being disposed along it. The apparatus transfers the cooling capacity of the plant from the cooler to the warmer side, so that a plant of minimum capacity may be used. The control may also be applied to the distribution of heat in a radiator system. Specifications 355,576 and 485,570 are referred to.
