Abstract: There is disclosed a method of equalizing the voltages of the individual cells of a storage battery that consists in the steps of,1. providing a single input circuit type of d.c. to d.c. converter incorporating multiple output circuits equal in number to the number of cells of the battery to which it is planned that the converter will make connection, with the converter so designed and employed that, with its input circuit connected to the terminals of the battery, and one of each of its output circuits connected across one of each of the cells of the battery, flow of cell equalizing current will hold low so long as the downward departures of the voltages of the battery's cells from average cell voltage hold below a prescribed index value.2.

Abstract: A method for controlling the charging of fast discharge and recharge type propulsion battery components of engine-electric hybrid drive systems for road vehicles, wherein the control objectives are to, minimize discharge of gas through battery cell vents, minimize fuel use, allow employment of a small battery, and provide for long discharge-recharge cycle life, and the control method consists in the steps of,1--providing so that, if not earlier terminated as a result of operator termination of braking, or a drop in vehicle speed, termination of regenerative braking will be initiated at a point in time determined by a control system generated indication of state of charge just prior to initiation of braking, and the subsequent history of cell current,2--providing so that, following a partial battery discharge, when and as motor speed allows, supplementary engine implemented battery charging will take place prior to the next advent of regenerative braking, with charge termination made responsive to attainment o

Abstract: There is disclosed a long life light weight alkaline storage battery taking the form of a two terminal linear array of cells, the sidewalls, tops and bottom portions of which comprise a pair of molded plastic frames of substantially rectangular section which are joined together in a leak proof manner, with each pair similarly joined to either a similar pair, or to an end frame, while the tube of substantially rectangular sections so formed is compartmented by a series of nickel or nickel plated steel end plates that are entered into the joints between frame pairs during assembly, and that, except in the case of outermost cells, have folded dual porous plate type electrodes, impregnated to be of opposite polarity welded to their opposite sides in such manner that they project perpendicularly from the surface of the end plates to which they are attached and possessing tapered leading edges with the foremost edge unimpregnated to facilitate assembly, there being provision so that, in the assembled battery, withi

Abstract: 1. In a torpedo detecting device of the class disclosed, the combination of n elongated hose-like member having a towing device secured to one end thereof whereby the member is adapted to be towed through a body of water, and means in said member and remote from said towing device for disconnecting said member at a predetermined point in closely spaced adjacency from the towing device comprising a helical coil of explosive fuse cord disposed only at said point and capable of sufficient explosive damage to sever the member substantially at said point, and a pair of electroresponsive detonators for firing said fuse cord, said detonators being disposed respectively in abutting relation to the ends of said cord.

Abstract: 1. In a torpedo detecting device of the class disclosed, the combination of plurality of hose-like sections, means for coupling the sections end to end to form a single streamer, said streamer including means for receiving and retaining air supplied under pressure thereto and a flutter valve for controlling the admission of the air thereinto, said flutter valve comprising a pair of axially aligned tubular members disposed to provide a chamber, and having axially aligned openings at the opposite ends thereof, a cylinder disposed therein to be movable between the openings in said chamber and in response to a predetermined difference in pressure on opposite sides thereof to shut off the air supplied to the streamer when the pressure differential between the air supplied under pressure thereto and the air under pressure therein exceeds a predetermined value.

Abstract: As an improved way of effecting fast valving of turbines of power system steam-electric installations of types that incorporate by-pass systems for by-passing steam from a point ahead of the high pressure turbine either directly to the condenser or to the cold reheat line, and in the latter case also from the hot reheat line to the condenser, and where the purpose of employment of fast valving is to improve the stability of power transmission over transmission circuits to which the generators of the installations in question make connection, when stability is threatened by line faults and certain other stability endangering events, the approach of rapidly closing intercept valves at fastest available closing speed in response to a fast valving signal, is supplemented by bringing into effect preprogrammed processes of control valve repositioning, plus intercept valve reopening, so effected as to cause turbine driving power subsequent to generator rotor first forward swing to hold below a preset value that is l

Abstract: As a improved way of effecting fast valving of turbines of power system steam-electric generating units for the purpose of improving the stability of power transmission over transmission circuits to which their generators make connection, when stability is threatened by line faults and certain other stability endangering events, the heretofore employed and/or advocated practice of automatically closing intercept valves at fastest available closing speed in response to a fast valving signal, and thereafter automatically fully reopening them in a matter of seconds, is modified by providing to reopen the valves only partially to and thereafter retain them at a preset partially open position.For best results the process of what can be termed sustained partial reopening is so effected as to result in its completion within a fraction of a second following the peak of the first forward swing of the generator rotor.
