Filed: 1967-04-13
Abstract: 1,192,202. Regulating I.C. engines. SOC. DES PROCEDES MODERNES D'INJECTION SOPROMI. April 13, 1967 [April 13, 1966; Dec. 9, 1966], No. 299/70. Divided out of 1,192,201. Heading F1B. The description is the same as the corresponding part of that of the parent, and it and the claims relate to a fuel injection system for an I. C. engine using electromagnetic injectors, each having an energizing coil which is associated with a capacitor which stores the energy released on the turning off of one injector coil and supplies this energy to boost the initial energizing of the next injection coil to be operated. The period for which an injector is open is made dependent upon such factors as induction and air pressures, engine and induction air temperatures, rate of accelerator depression, so-called "air filling coefficient", and advance or retard of injection time. In one embodiment a single storage capacitor 5001, Fig. 8 (not shown) is used for all coils (7<SP>1</SP>,8<SP>1</SP>,9<SP>1</SP>) and is charged through diodes (5003, 5004) from whichever coil is turned off by the cutting off of a power supply transistor (713<SP>1</SP>). When this transistor (713<SP>1</SP>) is next turned on and a coil-controlling thyristor (1021, 1022, 1023) is turned on a further thyristor (5002) is also turned on to discharge the capacitor (5001) through the selected coil. In other embodiments, one storage capacitor (4009), Fig. 2 (not shown) is connected in series with a diode (4005) across each coil (4007) or across a group of parallel connected coils Figs. 5, 6 (not shown). Each capacitor is crosscoupled to another. The injector coils are turned off in one embodiment Fig. 6 (not shown) by extinction thyristors (4029, 4028) one of which is associated with one set of coils (4007) and the other with a second set of coils (4008); these thyristors are fed with energy stored on capacitors (4007b, 4010b) and derived through diodes (4006b, 4005b) from the main storage capacitor (4009, 4010).

IPC: B60K5/04
Filed: 1949-01-07
Abstract: 663,212. Turning gear. GWILLIAM, V. C. E. MARTEN-. Jan. 5, 1950 [Jan. 7, 1949],  No. 541/49. Classes 7(ii) and 7(v) [Also in Group XXXI] A vehicular power unit, comprising an internal combustion engine integral with a clutch housing and gear box; is shown in transverse section in Fig. 5 and longitudinal section in Fig. 6. It comprises a pair of proprietory two - stroke  motor-cycle engines, each with flywheel. magneto ignition, secured to the opposite ends of a gear box, their crankshafts being coupled together by a transverse shaft 7. Drive is taken from the right hand end of shaft 7 through a torsional vibration damper, the inner member 8 of which is splined to the shaft 7, and the outer member 10 of which is formed with the sun pinion 9 of an epicyclic reduction gear. The planet carrier is formed as an oiltight drum 31 into -which oil is pumped from and returned to the main gear box by spiral grooves in the bearings, the epicyclic gear and the vibration damper being located in a compartment separated from the gear box by wall 33. The drum 31 is encircled by a brake band 41 carried by shoes 35 which are normally passed into engagement with the drum 31 by springs 37, but which can be separated to interrupt the drive by cam 39 actuated by lever 40 connected to the clutch pedal.

Title: Improvements in installations for feeding hydraulic servo-motors
IPC: B60T13/14
Filed: 1948-01-09
Abstract: 654,270. Hydraulic brakes. SERVO-FREIN DEWANDRE SOC. ANON. Jan. 9, 1948, No. 763. Convention date, Oct. 20, 1947. [Class 103 (i)] [Also in Group XXIX] In a hydraulic braking system comprising a normally continuously-running pump 1, a liquid tank 2, a pipe circuit 3, 5, 7 that feeds a servomotor steering-device 4, such as that described in Specification 654,269, [Group XXIX], and a pipe 8 that is led off the pipe 3 by way of a non-return valve 13 to feed a servomotor braking device 12 such as that described in Specification 640,542, a shut-off valve 6 is interposed in the pipe 5 which is arranged to be operated by the brake pedal 21 in conjunction with a piston 15 in a cylinder 10 connected to the pipe 8 at a point intermediate the valve 13 and the servomotor brake device 12. Passage 19 in the shut-off valve 6 is normally open to allow the pump 1 to circulate liquid without resistance through circuit 3, 5, 7 and back to the tank 2. Depression of pedal 21 to operate the brakes by actuation through rod 26 of a distributer valve in the servomotor device 12 simultaneously through rod 24 and spring connection 22 shuts off the valve 6 so that pressure is built up on the pump side thereof, which is transmitted through valve 13 and pipe 8 to the device 12. When, however, a certain pressure has been attained in pipe 8, the piston 15 in cylinder 10 is moved to the left against spring 17 to re-open the passage 19. So long as the pedal 21 is kept depressed the spring 22 will ensure that if the pressure to the right of piston 15 falls below a certain value, the valve 6 will again be shut, and the pressure above the non-return valve 13 will be restored to a value that is required to operate the device 12. In the system shown in Fig. 2, the shut-off valve 32, 33, 34 is not controlled in any way by the brake pedal 21 and the passage 33 is normally kept open by the pressure of liquid acting under the piston 30 in the cylinder 28 which forms a hydraulic accumulator. In the event of the pressure dropping, the piston is pressed down by the spring 31, thus closing the passage 33 so that liquid is pumped through the non-return valve 13 until the piston 30 has been raised again to re-open the circuit. The steering servomotor device 4 may be omitted from the system.
