Title: Fuel injection arrangement for internal combustion engines
IPC: F02M69/50
Filed: 1950-03-03
Abstract: 680,145. Fuel-injection pumps. KLOCKNER-HUMBOLDT-DEUTZ AKT.-GES. March 3, 1950 [May 4, 1949; May 27, 1949], No. 5482/50. Class 102 (i). In a fuel injection arrangement, fuel is fed by a pump 3 through a rotary valve 9 to an injection pump 4 from which the fuel is distributed to several cylinders by the valve 9. During the suction stroke of the pump 4, one of the diametral bores 17 connects the ports 18, 19 to permit flow to the pump and during the suction stroke, this connection is broken so that at the commencement of delivery, the ports overlap to provide sealing and prevent leakage. During the delivery stroke, fuel passes through pipe 8, port 30, annular groove 13 in the valve 9 and one of the ports 15 to an engine cylinder. Injection finishes when a bore 17 aligns with a port 22 in communication with the pump 4 and permits release through port 21 to pipe 20. The edge of the port 22 is inclined so that release is varied by moving the valve 9 axially. The bush 12 may be rotated by rack 29 to vary the timing. In the construction shown in Figs. 2 and 3, two fuelinjection pumps 108, 109 are provided, each having a rotary valve 125, 126 placed close to the pump and parallel to the eccentric shaft 102 and driven by gearing 132, 133. The feed pump is connected to inlet 116 and is connected to the injection pumps through a throttle 120. The pressure before the throttle 120, which is proportional to the engine speed, acts on a piston 114 loaded by a spring 121. The piston 114 actuates a member composed of two parts each having a projection 151 engaging slots 152 in bushes 138, 139 surrounding the valves 125, 126 to vary the time of injection; the two parts may be adjusted relatively to each other by a screw 154 so that the timing controlled by each valve may be adjusted; each bush may also be adjusted longitudinally. The valves are adjusted axially by a rod 137. A relief valve 156 is fitted beyond the delivery valve 140 of each pump.

Abstract: 234,205. Field, E. D. March 4, 1924. Springs, arrangement of and mounting undercarriages on. - Four longitudinal flat springs arranged in pairs, one pair at each end of the frame of a baby carriage, invalid carriage, &c., each have one end connected to a wheel axle and the other end connected by a bracket &c. to the frame so that both pairs of springs are inside or outside the frame, or one pair inside and the other pair outside the frame.

The springs may be bent so that both axles lie above or below the frame or one axle above and the other below. The body may be supported on the chassis by straps or - other devices, and the springs a, b may be formed of one or more plates. The Provisional Specification describes the springs applied to a single-axle vehicle or to one axle of a two-axle vehicle; also, the use of coil springs to support the axle-ends when long springs are used, and the continuation of the springs to form body-supporting cee-springs.

Title: Catch nozzles for steam cooled explosion turbines
IPC: F02C5/12
Filed: 1927-06-23
Abstract: 297,281. Holzwarth Gas Turbine Co. of America, and Holzwarth, H. June 23, 1927. Divided on 296,154. Working-fluid supply.-In a turbine actuated by combustion-products and high-pressure steam issuing from separate nozzles 14, 13 and in which the steam exhausting from the rotor blades 12 is collected in a catch nozzle 17 to prevent mixing with the gases, the catch nozzle is formed with a radial flange 20 secured to the stator ring 21 carrying the fixed blades 15 so as to prevent outward leakage of steam. The catch nozzles at the other end slide fluid-tight in housings 22 in the turbine casing 23 to permit of relative thermal expansion. The collected steam passes into chambers 32 in the turbine casing and is heated by the gases coming from the rotor. The collecting nozzle end walls with the segmental apertures therein extend circumferentially a sufficient distance to prevent lateral leakage. Fig. 9 shows the provision of an auxiliary steam, gas, or compressed air nozzle 36 to blow out the gases which have been carried round in the turbine blades to prevent their being driven into the collecting nozzles 17<1> by the steam coming from the main nozzles. The catch nozzle in this construction is formed with partition walls 37 to avoid leakage by the fan action of the blades and also with external guide blades 38 to direct the gases so that disturbance of the steam flow is avoided.

Abstract: 973,470. Transistor switching circuits. F. G. HEATH. Feb. 21, 1961 [Feb. 24, 1960], No. 6530/60. Heading H3T. [Also in Division H1]  Equal inputs of either earth potential or of a voltage - V applied to input terminals 1, 2 of an "Exclusive -OR" circuit, result in an output at earth potential being produced at the collector electrode of transistor 3, while different inputs, i.e. one of earth potential and one of- V volts, applied to said input terminals result in a negative-voltage output being produced at said collector electrode. If earth-potential inputs are applied at 1 and 2, transistor 3 is cut-off so that no current flows in resistor 7 and earth-potential also appears at the output terminal. The relative values of resistors 12 and 8 are so chosen that when one only of inputs 1, 2 is at - V volts, the other remaining at earth potential, the base electrode of transistor is still biased positively and the voltage of the junction point of resistors 10, 11, viz. - V/2 volts, appears at the output since the transistor remains cut-off. When however both inputs are at - V volts, the transistor conducts so that earth potential appears at the output terminal. The polarity of the output may be reversed and the output magnitudes made to equal the input magnitudes by connecting the output terminal to the base electrode of a further switching transistor having its collector electrode connected through a load resistor to a bias source of- V volts, Fig. 2 (not shown).

Abstract: 780,518. Hydraulic presses. CKD CESKA LIPA, NARODNI PODNIK, and VLTAVSKY, M. March 1, 1955 [March 1, 1954], No. 6049/55. Class 69 (2). In an hydraulic press an approach stroke of a press ram is made at high speed, exhaust of liquid from the underside of the ram being restricted immediately prior to the engagement of the work by the ram so that the ram contacts the work at low speed, the reduction in pressure of liquid beneath the ram consequent upon the ram engaging the work resulting in the'application of full working pressure. A pump 6 supplies liquid to the press cylinder 1 under the control of a distributing valve 3. With a solenoid 4 energized and a solenoid 5 deenergized valve 3 is held in its neutral position (shown) in which the working space 17 of the press cylinder is open to exhaust, the pump output is by-passed and the return space 16 is blocked, so that the press ram 2 is retained in position. To initiate a working stroke a contact 20 is closed to energize the solenoid 5 and the valve 3 is thereby moved to its uppermost position so that the pump delivers to the working space 17 and the space 16 is open to exhaust. A rapid approach stroke is thus obtained. When the ram contacts a collar 15 a contact 11 is opened and the solenoid 4 thereby de-energized. Valve 3 is thus lowered by a spring to a position limited by a stop 18 in which the space 17 is open to exhaust and exhaust from the space 16 is throttled. The ram falls slowly under its own weight, the rise in pressure in the space 16 acting upon a piston 12 to open a contact 14. Continued movement of the ram closes a contact 10, and when the ram contacts the work the drop in pressure in the space 16 enables the contact 14 to close so that the solenoid 4 is energized and full pressure is again applied to the ram. To effect a return stroke switch 20 and a switch 21 are opened to deenergize solenoids 4, 5, valve 3 is thus moved into its lowest position and liquid supplied to the return space 16 to raise the ram. After the contact 11 has closed the ram will be held stationary when the contact 21 is closed.
