Title: Improvements in internal combustion engines in which water is injected into a combustion chamber during operation
IPC: F02B1/02
Filed: 1949-08-12
Abstract: 657,891. Cycles; regulating. DARCHE, A. A .A. Aug. 12, 1949, No. 20609/47. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 3, 1948.] [Classes 7(ii) and 7(vi)] The combustion chamber is divided into a main combustion chamber C<SP>1</SP> provided with ignition means D and an'auxiliary chamber C<SP>2</SP> communicating with the main chamber, and carburetted air is introduced in the course of the suction stroke through the auxiliary chamber into the engine cylinder the carburetted air being thus led indirectly into the main chamber and after the end of the suction stroke and during at least part of the compression stroke water or a liquid hydrated fuel is injected into the auxiliary chamber through the nozzle I with the result that it is retained by the compression pressure and that the carburetted mixture in the main chamber is free from any aqueous liquid so that as the mixture is ignited in the main chamber the combustion will begin in the main chamber that contains carburetted air and is completed in the auxiliary chamber that contains a mixture of carburetted air with water. The amount of water injected into the auxiliary chamber is adjustable so that the percentage of carburetted mixture forced into the main chamber during the compression stroke is made dependent on the amount of water injected which makes it possible to control the pressure obtained at the end of the compression stroke. Injection may be continued during the combustion period. Preferably the injector is aligned with the longitudinal axis of the auxiliary chamber. In a modification the chambers C', C<SP>2</SP> are separated by a projection on the cylinder head instead of by a projection B on the piston as shown. The Specification as open to inspection under Sect. 91, states also that the auxiliarv chamber is preferably cylindrical, injection taking place along the axis of the chamber and communication with the main chamber being established at the end of the auxiliary chamber remote from an iniector for the water. The moment at which injection commences is variable in accordance with the load and/or speed of the engine. A continuous flow to the auxiliary chamber takes place during the whole of the injection period. This subjectmatter does not appear in the Specification as accepted.

Abstract: 574,435. Gramophones. SOUNDSCRIBER CORPORATION. Dec. 9, 1943, No. 20612. Convention date, Oct. 29, 1942. [Class 40 (ii)] A gramophone recording or reproducing head is pivotally mounted approximately at its centre of gravity in the forked end of the recording or reproducing arm and is spring- urged against the record so that the effect of gravity is eliminated and the stylus engages the record with constant pressure at all times. The invention is applied to the recording and reproducing heads 24, 39 of a combination recording and reproducing machine utilising a record 13 of aluminium or plastic sheet. The recording head 24 is pivoted near its centre of gravity on screws 26, 27 between the prongs 19, 20 of the forked end of a comparatively wide, flat-shaped arm 14 carried by a vertical pivot 15. The recording stylus 25 is pressed against the record by the action of a coiled tension spring 32 stretched between a tailpiece 29a on the recording head and a lug 32a on a bar 33 held above the arm 14 by two rods 34, 37, one of which is screw-threaded and provided with a pair of nuts 38 to clamp the bar 33 at the requisite height to give the desired tension in the spring. The recording head is hollowed out underneath to reduce weight. The screwthreaded joints between the recording head and its pivots have a damping action. The pick-up 39 is similarly mounted; but its supporting arm 16 is narrower, and the pivots are conical points 42, 43, little damping being required with the lighter pressure of about half an ounce required on the reproducing stylus. Specifications 539,534 and 558,552 are referred to.

Abstract: 982,173. Vehicle fluid transmission systems. JOSEPH LUCAS (INDUSTRIES) Ltd. June 12, 1961 [June 13, 1960], No. 20648/60. Heading B7H. A vehicle transmission has an engine-driven swash-plate pump 5 supplying pressure liquid to a motor 6 for driving the wheels of the vehicle, liquid actuated means 7, 8 vary the stroke of the pump and/or motor automatically to accord with the load on the motor, and a driver operable valve 16 in series with an engine speed responsive valve 10, whereby on valve 16 being actuated when engine speed is below a predetermined value, the means 7, 8 is operated to lower the speed ratio between the engine and the vehicle. Chambers on either side of diaphragm 18 in valve 10 are connected directly and via choke 19, respectively, to engine-driven pump 21, a valve 12, 13 connected to the diaphragm being biased open by spring 14. A variable restriction 22 is set by accelerator pedal 23. In Fig. 1, with engine speed below the predetermined value, valve 12, 13 opens and on braking of the vehicle valve 16 opens and fluid flows from cylinder 8 to decrease the speed ratio until piston 7 closes port 9 to aid braking. The lowest speed ratio to which the transmission can be set can be selected by using a series of ports 9, 9a, 9b, 9c, and a manual valve 25, which can replace valve 16 if all the ports can be closed by valve 25. In Fig. 2, on braking a second brake valve 30 connects valve 10 to valve 31 connected to reservoir 17 via port 33. A pivoted lever 34 biased by spring 42 to open inlet 32, is acted upon by pistons 37, 38 connected by pipes 39, 40, respectively, to the line between the inlet of pump 5 and outlet of motor 6 and to a cylinder operated by brake pedal 41. Pressure rises in pipe 39 when motor 6 tends to drive pump 5. For a given brake pressure, valve 32 is opened to reduce the speed ratio until the forces on lever 34 balance. Hence if the torque transmitted from the wheels to the engine is high, the valve 31 closes to stop further speed ratio reduction at a lower pedal pressure as compared with instances when the torque transmitted to the engine is low. A valve 44 operated from the hand brake lowers the speed ratio on application of the hand brake with the vehicle speed below a predetermined value.

Abstract: 1,117,663. Starting prime movers. K. G. CORFIELD Ltd. 21 June, 1966 [19 May, 1965], _ No. 21119/65. Heading H2H. Apparatus for starting an internal combustion engine comprises a relay 25 having two opposing energizing coils 28, 29 the arrangement being such that when the engine is running and an output is being derived from the alternator/rectifier unit 12, the starting mechanism is disabled. Closure of a push button 31 causes energization of the winding 28 by the battery 11 to close the contacts 26 to energize the starter motor solenoid 13 so that the starter motor 10 runs to start the engine. As soon as the generator 12 is rotating to produce an output-and with the push button 31 still closed-the winding 29 is energized and, since its energization opposes that of winding 28, contacts 26 open to de-energize the starter motor 10. The relay 25 cannot again be operated unless the engine is stopped. The battery 11 is charged from the generator 12 by way of a diode 32 and the generator output is regulated by a regulator 21. The starter motor solenoid 13 is of the type wherein one contact (16) closes first so that the starter motor is supplied with reduced energization by way of a resistor 17 after which another contact (15) closes to provide full excitation for the motor. Lead 23 supplies auxiliaries independently of, and lead 24 dependent upon, operation of the ignition switch 22.
