Title: Battery Charging Apparatus
IPC: H02J7/00
Filed: 1981-11-20
Abstract: A battery charging system is responsive to the internal impedance of the battery. A comparator (1) compares the actual battery voltage with a reference voltage (8) to terminate a first phase of charging when a pre-set voltage is reached. In a second phase, battery impedance, obtained by dividing battery voltage by battery output current, is in one embodiment compared with a fixed reference value (14), charging being terminated when a predetermined relationship between the actual value and the reference value is reached. In another embodiment (Figure 2) the first value of impedance obtained is put in a store (13) and battery impedance is then determined at predetermined intervals. The new value is compared to the previous value held in the store and then the new value is inserted in the store. The second phase of charging is terminated when a predetermined relationship between the new value and the value held in the store is reached. <IMAGE>

Title: Multiple windings electrical motors controllers
IPC: H02P7/00
Filed: 1981-09-17
Abstract: Controllers for brush-type multiple windings electrical motor. There has been a lack of a reliably-operating, efficient controller for such brash-type machine. The invention provides for torque control of a multiple winding electrical motor by operating various numbers of electrical switches which energize various numbers of torque generating winding sets within the motor and by positioning a brushholder. These controllers are for a class of commutator-brush type motors which have multiple open circuit armature windings (60-61 et al. and 197-198 et al.) and multiple brushes (13, 14, et al. and 157 through 172) contacting most of the commutator (88 and 223) segmented surface. These controllers provide torque control of these motors by operating various electrical switches (1 through 8 and 108 through 124) which vary the number of torque generating winding sets (9-10, 11-12 et al. and 125-126, 127-128 et al.) energized. This invention discloses how brushholder (82 and 222) position is used to control motor torque direction and magnitude. This invention also discloses how electromagnetic energy is recovered from interrupted open circuit armature windings (60-61 et al.) using diodes (35 through 50).

Title: Zinc and tin plated steel sheet
Inventor: NEMOTO TADASHI
IPC: C25D3/22
Filed: 1982-09-03
Abstract: The sheet is produced by electroplating zinc on a steel sheet followed by tin-plating the zinc plated steel sheet by immersion (optionally followed by electroplating) in a tinplating bath containing stannous ions, whereby zinc ions from the zinc plated steel sheet replace the stannous ions in the tinplating solution during the immersion tinplating. The resultant solution from the tinplating which contains zinc ions is recycled to make up the zinc electroplating bath. The plated sheet may be heated above the melting point of tin to form an iron-tin alloy, treated cathodically or by immersion in a bath of Cr VI ions or subjected to a phosphate or sodium carbonate treatment.   The sheet has 0.0005-0.2 g/m<2> of zinc and 0.05-1.0 g/m<2> of tin and has excellent weldability, and corrosion resistance. It can be used to produce car bodies.

Title: Process for treating spent silicon-containing reaction masses to produce halosilanes
Inventor: RITZER ALAN
IPC: C01B33/107
Filed: 1983-03-29
Abstract: Improved yields of monohydrogentrihalosilanes are achieved by contacting the residual silicon obtained from the preparation of organohalosilanes by a metal-catalyzed direct process by contacting the residual silicon simultaneously with gaseous hydrogen halide and with gaseous alkyl halide to form a residual silicon contact mass; selecting a temperature between 200 DEG C. and 350 DEG C. at which alkylation of the silicon contact mass in inhibited and at which hydrohalogenation of the silicon contact mass occurs; and heating the silicon contact mass at the selected temperature. The silicon reacts with the gaseous alkyl halide and the gaseous hydrogen halide at the selected temperature to produce improved yields of the monohydrogentrihalosilane.

Title: An apparatus for controlling a fuel pump
Inventor: ADEY ANTHONY JOHN
IPC: F02D41/06
Filed: 1983-04-14
Abstract: An apparatus for controlling a fuel pump comprises a governor circuit 15 which provides the normal fuel signal to an actuator control circuit 13 by way of a switch 16. A first memory 20 contains information relating to the required excess fuel quantity against engine temperature for starting the engine and provides another input to the switch. The switch is controlled by a comparator 17 which receives at one input the engine speed signal and at its other input a signal provided by a second memory 18. This contains information relating to the maximum allowed engine speed against engine temperature below which excess fuel can be supplied. For starting the switch selects the output of the first memory for supply to the control circuit 13 but as soon as the engine speed exceeds that determined by the second memory for the engine temperature the switch is latched in its alternative state in which the governor circuit 15 provides the normal fuel signal to the control circuit 13. <IMAGE>
Patent GB-2120014-A (GB)
Title: Electrical switch
Inventor: LITTLE PHILIP VERNON
IPC: H01H13/26
Filed: 1983-04-29
Abstract: A switch comprises a housing 11 in which is disposed fixed contact means and a slider 10 which carries movable contact means 27, 28 and which is mounted for slidable movement within the housing 11. The slider 10 (or the housing 11) is formed as a synthetic resin moulding which has integrally moulded therewith at least one projecting resilient finger 17, 18 which is/are engageable, during movement of the slider relative to the housing, with abutment means 25, 26 formed in the housing 11 (or on the slider 10). The inter-engagement of the or each resilient finger and the associated abutment serves to flex and stress the finger so that after the finger and the abutment are disengaged the finger will recover its original unflexed position and in so doing will release energy stored during the flexing and thereby cause relatively rapid movement of the slider 10 relative to the housing 11 between positions represented by an "on" position of the switch and an "off" position thereof. <IMAGE>
