Filed: 1965-08-31
Abstract: 1,122,057. Battery charging circuits. GENERAL ELECTRIC CO. 31 Aug., 1965 [14 Sept., 1964], No. 37159/65. Heading H2H. [Also in Division H3] A battery charging circuit comprises a gate turn-off thyristor 13 forming part of a commutating circuit 13, 31 which is turned on when a capacitor 25 charged from an A.C. or D.C. supply 67, 68 discharges at a determined voltage through a disc 27, a Shockley diode or a similar breakdown device. The voltage induced in an air-gapped transformer 14, 16 charges the battery 48 through a rectifying device 49. When the potential across a capacitor 32 is sufficient, the thyristor 31 will fire through circuit 33-35 connecting the capacitor 32 to the gate of thyristor 13 turning it off. A look-out circuit is provided by a winding 17 which through rectifiers 36, 37 renders a transistor 41 conductive to shunt capacitor 25 while the current is changing in transformer 14. A second lock-out circuit is provided by diodes 42, 43, resistor 44, diode 19 and resistor 21 to maintain a potential across diode 33 while current through the transformer primary is decreasing. A capacitor 45 shunts thyristor 13 thus assisting turn-off and counters the inductance of the transformer 14, 16 by discharging on turn on. The battery may have a reference electrode 52 which through a relay 53, 54 shunts the capacitor 25 at a determined potential. Alternatively, transistor 41 may be rendered conductive by the battery potential. In an alternative arrangement an ampere-hour meter may turn off the battery circuit. A thermal switch 22 in contact with the heat sink may switch off the supply at a determined temperature.

Title: Anti-lock device
IPC: B60T8/42
Filed: 1972-08-15
Abstract: 1385936 Anti-skid systems; valves WAGNER ELECTRIC CORP 15 Aug 1972 [17 Nov 1971] 37938/72 Headings F2F and F2V Upon sensing of an impending skid condition by a velocity sensing device and an electronic circuit, a solenoid assembly 74 is energized to move an armature 78 and thereby actuate a control valve 59 ; this causes air to be communicated to a chamber 12 of a vacuum suspended power housing 2 to move a diaphragm 10 leftwards against the bias of springs 18, 19 in a chamber 11; with the diaphragm 10 is also moved, by the action of prevailing braking pressure, a control piston 41 which allows a valve 33, 38 between an inlet port 34 communicating with a master cylinder or pump and an outlet port 35 communicating with a wheel cylinder to close; the wheel cylinder is thereby cut off from further pressure increase and as the piston 41 continues moving leftwards pressure in the wheel cylinder is reduced to remove the skid condition. When the skid condition is removed the solenoid 74 is de-energized and the components return to their normal positions with air being exhausted from chamber 12. The control valve 59 comprises a stem portion 60 with opposed valve members 61, 62 cooperable with respective valve seats 48, 49. In the normal position of the valve 59, member 62 engages seat 49 and member 61 is disengaged from seat 48 whereby a port 51 permanently connected to vacuum is connected to chamber 12 via a recess 50, open valve 48, 61, a chamber 45, a bore 79 and orifices 92 in a throttling mechanism 82; vacuum port 51 is permanently connected via a conduit 53 to the chamber 11. When the valve 59 is actuated member 61 engages seat 48 and member 62 is disengaged from seat 49 whereby an atmospheric port 58 permanently connected to a chamber 47 around member 62 is then connected to chamber 45, bore 79 and chamber 12. As shown in Fig. 3 the throttling mechanism 82 comprises a spring biased cup-shaped member 86 with a passage means 87 therethrough and provided with a valve seat 88 for diaphragm 10: the mechanism 82 also comprises a body portion 83 co-operable with valve seats 81a around apertures 81 in a wall 8 to form unidirectional check valves 91. When air is introduced into passage 79 upon operation of control valve 59 air flows through apertures 81 to thereby open check valves 91 and introduce air into chamber 12. The diaphragm 10 moves leftwardly and with it the member 86 until a flange 89 thereon abuts body portion 83, whereupon diaphragm 10 lifts from valve seat 88 to allow the rapid introduction of air into chamber 12. On subsequent return of control valve 59 to its normal position, exhaustion of air from chamber 12 first takes place through open valve 10, 88 and then through restricted orifices 92. In the embodiment of Figs. 5, 6 (not shown) the throttling device (100) comprises a stepped piston (106) with a passage (107) therethrough and uni-directional flapper valves (113) formed by co-operation of a valve portion (115) with seats (116) surrounding apertures (112) in piston (106). The portion (115) also has restricted orifices (117).

Abstract: 1,182,139. Pneumatic conveyers. G. BOULADON. 21 Aug., 1967 [24 Aug., 1966], No. 38349/67. Heading B8A. [Also in Divisions B7 and F2]  A system for the pneumatic conveyance of a unit 2 comprises a propulsion tube 1 longitudinally divided at 3 into an upper segment 4 along which the unit 2 moves and a lower segment 5 which is divided into chambers 6 n , &c. which communicate with the upper segment 4 via valves 17, reversible fans 9 n , 10 n  &c. in each chamber 6 n  delivering pressurized air upstream and a vacuum downstream, of the unit 2 to facilitate movement thereof. A detector 18 n , of contact or proximity type is associated with each chamber 6 n  and when operated by a unit 2 causes the fans in the next downstream chamber 6 n+1  to reverse from vacuum to pressure air supply as the unit passes over that chamber. The fans may have reversible motors or blade pitches. The valves 17 over any one chamber 6 n  &c. open to permit air to pass from the chamber to the upper segment 4, when the pressure in segment 4 is lower than that in the chamber, but above a reference pressure and open to pass air from the segment 4 to the chamber 6 n  when the pressure in the segment is above that in the chamber. However, if the pressure in the upper segment is below the reference value, the valve closes. A plurality of detectors 18 n  may be associated with each chamber whereupon the speed of the unit 2 can be determined and the fan control may be automatically advanced so that the pressure in a chamber downstream of the one adjacent the chamber containing the detector is conditioned. The tube 1 is divided by doors 25, 26 into sections each of which may have a unit 2 running therethrough. To facilitate movement of a unit 2 in either direction along the tube 1, remotely operated reversible switches 19 n  &c. are coupled in circuit between the detector and the fans so that the fans in chambers to either side of the chamber associated with the detector may be controlled by the detector.
