Title: Improvements in devices for operating internal combustion engines with an ignition chamber
IPC: F02B19/14
Filed: 1925-09-10
Abstract: 241,870. Krupp Germaniawerft Akt.- Ges., F. Oct. 27, 1924, [Convention date]. Cylinders receiving liquid fuel. - In engines comprising an ignition chamber in constant, communication with the cylinder, and in which is produced an auxiliary explosion by which the fuel is blown into the cylinder, the communication between the ignition chamber and the cylinder is established by two or more channels one of which is constantly open, while the others each contain a check valve which opens towards the ignition chamber. A member B fitted to the cylinder cover A has screwed to it the ignition chamber C with a hemispherical top. Communication between the cylinder and the ignition chamber is effected through passages b<1>, b<2> of which b<1> is unobstructed and permanently open and receives fuel through the lateral duct b<3>, whilst b<2> contains a check valve D. Cooling water circulates through the spaces b<4>. The use of two or more channels ensures that an abundant supply of air passes into the ignition chamber during compression, whilst the closing of the check valves during explosion in the chamber C maintains the pressure in that chamber at such a value as to ensure good atomization of the fuel during injection- Good whirling and atomization in the ignition chamber are obtained by placing the passages b<1>. b<2> near the walls thereof Fig 1, the streams being caused to impinge by the hemispherical top. In the modification Fig. 2, a similar effect is produced by connecting the passage b<2>, through a pipe E. with the centre of the top of the chamber. In a further modification, the passage b<1> terminates in several spraying orifices and the passage b<2> is arranged to deliver its air in the form of a helix.

[Also in Division F1] A water heater, Fig. 1, comprises an oscillating gas column combustion chamber 1 (see Division F1), having an exhaust tube 2 leading into an expansion chamber 3, silencer 4 and exhaust pipe 5. Water to be heated is fed in at the bottom of an insulated jacket 17 and leaves at outlet 19. Partition 18 separates the water from the fuel and combustion air supply apparatus. A thermostat may cut-off the fuel supply to the chamber 1 when the water temperature becomes too high. The heating appliance may be used to heat air instead of water in an unspecified manner. Combustion within the chamber 1 is initiated by closing the electric mains switch 23, Fig. 3, to energize ignition coil 16 and sparking plug 14, fan 22 supplying air to the chamber, thermostatic switch 25 and hot wire vacuum switch 26. After a shot delay, switch 26 energizes solenoid valve 27 to supply gas to the chamber 1. If combustion commences, pressure within a throttle builds up and closes contacts 24b of pressure switch 24, thus de-energizing plug 14 and switches 25, 26. If combustion is not established, contacts 24b do not close and after about 20 seconds a heating coil causes contacts 25a to open to break all circuits. When the coil has cooled, contacts 25a close and the cycle is repeated until combustion occurs. Specification 977,354 is referred to.

Title: Improvements in or relating to navigating instruments for air and other craft
IPC: G01C19/44
Filed: 1944-11-27
Abstract: 590,346. Thermionic valve circuits. REID, G. H., and COOK, R. J. Nov. 27, 1944, No. 23649. [Class 40 (v)] [Also in Groups XXXIII and XXXVIII] In a navigating instrument for aircraft, a trace is produced on a cathoderay tube which represents pictorially the attitude of the aircraft as seen by a person flying on a level course behind the aircraft. In the control system, Fig. 4, a flat-topped wave is applied through an electronic potentiometer 9 to the plate y<1> of a cathode-ray tube, to give a vertical trace representing the fuselage, the amplitude varying from zero to a maximum as the potentiometer responds to pitching of the aircraft. A second voltage of double frequency having alternate cycles of reduced amplitude is applied to plate x<1> so that the large amplitude pulse produces a horizontal trace representing the wings during the flattopped portion of one half-cycle of the wave applied to plate y<1> and the small amplitude pulse produces a trace representing the tail during the flat-topped portion of the other half-cycle. In order to produce the wave with alternate cycles of reduced amplitude, a voltage of double frequency is applied to the grid 14 of pentode 15, a flat-topped wave of normal frequency being applied to the supressor grid 16 so that during the negative half-cycles of the wave applied to grid 16, the anode current of the pentode is reduced. The potentiometer 9 comprises tubes 24, 25, Fig. 6, in parallel having their grids 27, 28 fed with voltages of opposite phase. The output from coil 35 which is rotated by an instrument responsive to pitching varies from zero to a maximum as the coil rotates through 180 degrees and attains a value between these two extremes during level flight. The grid 40 of valve 25 is biassed so that during level flight the anode currents of valves 24 and 25 are equal so that there is no output at the anodes since the grids 27, 28 are fed in opposite phase. Thus, the trace will not be deflected in a vertical direction and the traces for tail and wings will coincide. When the aircraft climbs or dives, coil 35 rotates and the output rises or falls. The plates of valves 24, 25 therefore receive an alternating voltage whose amplitude varies with the amount of deviation of the craft from a level position and whose phase depends upon whether a climb or dive is indicated. Potentiometers 23 and 42 are also included and are responsive to banking and yawing of the aircraft. A highfrequency ripple may be given to the applied voltages, e.g. when diving, so that the trace assumes a spotted appearance so as to differentiate the undersurface from the upper. Specification 425,111, [Group XX], is referred to in the Provisional Specification.

Abstract: 534,026. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and DOWNES, F. A. Aug. 17, 1939, No. 23756. Drawings to Specification. [Class 118 (ii)] In a progressive system wherein the local controllers are controlled by pulses from a master controller and wherein the traffic cycle for each intersection includes a prevent period for ensuring that right of way is available for the main road when required, it is arranged that at an intersection where the times of arrival of groups of " up " and " down " main road traffic according to the signalling plan are spaced by an interval exceeding the minimum green period for the side road, separate prevent periods are allotted for the up and down traffic, each of which is at least equal to the minimum green period aforesaid. During such a prevent period, right of way cannot be transferred to the side road, but if right of way is on the side road it can be retained by demands thereon. Each prevent period may continue until the time of arrival of the leading vehicle of the appropriate traffic group in the manner described in Specification 534,027 and then give place to a vehicle-actuated period, but preferably it ends slightly before that time and a short privilege period intervenes during which right of way is transferred to the main road immediately it is required and demands on the side road are ineffective. The local controller described, which operates generally on the lines of that disclosed in Specification 504,552, receives from the main controller 9 pulses per cycle to initiate and terminate the prevent and privilege periods for the two directions of main road traffic and for the side road. This necessitates the provision of three pairs of preference relays. The Provisional Specification states that the system disclosed in Specification 450,602 may be modified to operate according to the present scheme. Specifications 408,706 and 509,695 also are referred to.
