Title: Fuel pulverizing and vaporizing injector for internal combustion engines
IPC: F02M67/10
Filed: 1924-02-07
Abstract: 223,468. Rochefort, F. Feb. 7, 1924. Cylinders receiving liquid fuel.-Fuel passes to the spraying point around the periphery of a piston-like member upon which the fuel acts to open an injection valve which controls admission of both air and fuel to the cylinder. In Fig. 1, spiral passages m<1> are provided on the cylindrical portion m of the injection valve l. The fuel, supplied by the passage d<1>, acts upon the lower end of the member m to lift the valve, and passes to an annular groove k<3> in the valve seating through the passages m<1>. The spraying air is admitted at c, and on the lifting of the valve l passes through grooves l<4> in the stem of the valve to the annular groove k', whence it carries the fuel into the cylinder through passages k<4> and spiral grooves k<5>. Orifices l<6> are formed in the upper end of the valve l, to ensure that the pressure of the injection air shall be exerted on the valve to assist its closing; and orifices l<5> in the lower end of the valve drain away any accumulation of fuel from the interior of the valve. In a modified construction the piston-like member m is made slightly smaller than the housing within which it works, the fuel passing to the spraying point through an annular passage around the member. The injection valve has an annular flat face and seating, and controls a plurality of convergent-divergent spraying passages opening into the seating.

Title: Improvements in or relating to devices for the electrical control of the components of mixtures
IPC: G05D11/13
Filed: 1962-01-30
Abstract: 981,564. Mixing flowing liquids in proportions. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES. Jan. 30, 1962 [Feb. 2, 1961], No. 3459/62. Heading B1C. [Also in Division G3] The flow of constituents of a mixture is kept constant by a digital control circuit in which may be set independently both the proportion of each constituent and the total flow of the mixture. Pulses representing actual flow of each constituent A, B, C are compared numerically in devices 24, 28, 30 with reference pulses, the number of which is determined by the setting of selector switches (16, 17, 18 for A) in parallel outputs of a common ring counter 10, 11, 12, and the resultant used to adjust flow regulating valves. The reference pulses are derived from a constant frequency pulse generator 1 connected to an auxiliary counter 2, in the output of which is a selector switch 4 whose setting determines how many pulses in each counting cycle are passed to the ring counter 10, 11, 12 by "and" gates 3 and 9; hence the total flow of mixture is controlled as a percentage of the total possible, which corresponds to all the pulses being passed to the ring counter. The adjustment to the flow is made at the end of each counting cycle, and the start of the next cycle is delayed for this to be effected. It is stated that the counters may comprise bistable circuits having transistors, valves or gasdischarge tubes, and each is associated with a decoding matrix comprising diodes. In an alternative arrangement the selector switches are replaced by punched card setting devices.
