Title: Improvements in and relating to control systems for the motors of electrically driven vehicles employing regeneration for braking purposes
IPC: B60L7/12
Filed: 1932-12-29
Abstract: 417,502. Master control of D.C. motors; controllers. WILLIS, A. M., 59, Victoria Street, Bristol. Dec. 29, 1932, No. 36798. [Class 38 (iii).] Regenerative braking.-A compound-wound vehicle motor is controlled during motoring and regeneration by power and brake controllers respectively, the brake controller being adapted to regulate the shunt field, and to modify the series field so that the series and shunt excitations do not oppose, and the connection of the armature to the supply being made automatically upon operation of the brake controller, only when conditions are suitable for regeneration. A controller 5 is operated by a pedal 9 in an anti-clockwise direction to connect the compound-wound motor 13 to the supply, and accelerate it by first cutting out series resistance 29 in steps, and then inserting resistance 33 in steps in the shunt field 2, the line contactors being maintained by a switch 10 frictionally operated from the controller shaft so that return movement of the controller disconnects the motors, and allows the vehicle to coast. With the motor disconnected, and its speed such that a centrifugal switch 90 is closed, and the back E.M.F. is in excess of the line voltage, so that a differential relay 95 is closed, operation of the controller 5 in a clockwise direction by means of a pedal 8, causes contactors 27, 103 to close and connect the armature to the supply, the vehicle being regeneratively braked, and slowed down by further clockwise operation of the controller 5 to cut out, in steps, resistance 109 now included in the shunt field circuit which also includes the series starting resistance 29, and the series field 1, final clockwise movement of the controller releases the air brakes, the relay 95 is provided with an anti-hunting coil. In a modification, two separate electrically interlocked controllers for driving and braking are provided, and when, during regenerative braking, the motor has been connected to the line, the control of the line switches is transferred from the voltage balance relay to a cut-out relay which disconnects the motor when the armature current changes from regenerative to motoring, the voltage balance relay again effecting the automatic connection for regenerative braking if and when the armature voltage is suitable. The cut-out relay may be polarized and one coil of the voltage balance relay may be connected across a motor line switch. Movement of the braking controller may short-circuit the series field. A resistance in the vehicle lighting circuits is automatically switched in on excess voltage.

Abstract: 942,124. Valve oscillating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 28, 1962 [Oct. 3, 1961], No. 36900/62. Heading H3F. In a supersonic oscillator whose load circuit comprises a piezo-magnetic transducer 8, the feedback is taken from the winding of a second transducer 18 rigidly secured to the first. The two transducers have substantially the same natural frequency and are so orientated that their windings are magnetically decoupled from one another. The windings of the transducers and also the secondary and primary respectively of impedance matching input and output transformers 12, 5 respectively, are resonated at the natural frequency of the transducers by means of capacitors 21, 23, 24 and 22 respectively. As shown, the transducers consist of I-shaped members of low-loss piezo-magnetic material, e.g. ferroxcube, with interposed bias magnetization plates 10 and 10<SP>1</SP> of permanent magnetic material, e.g. ferroxdur. The magnetic decoupling between the two transducers may be improved further by interposing between them a plate of ferromagnetic material having a high permeability. In an alternative embodiment, Fig. 3 (not shown), transducers having open magnetic circuits are used and magnetic decoupling between the windings is obtained by means of transverse pieces of high permeability material. The arrangement has a conversion efficiency which is high, and remains high when it is mechanically loaded.

Title: Welding method and welding elements therefor
IPC: C09D127/12
Filed: 1962-10-04
Abstract: Welding rod or filler wire has an outer coating, inner core or integral filling of fluorocarbon polymer.  The polymer is preferably polytetrafluoroethylene or fluoroethylene propylene but may be polyfluoroethylene propylene, polychlorotrifluoroethylene, polyvinylidene fluoride, polyvinyl fluoride, hexafluoropropylene, or a copolymer of vinylidene fluoride and hexafluoropropylene; mixtures of polymers can also be used.  The polymer may be applied directly on to the surface of a solid welding rod, or the polymer coating may be applied over a pre-applied flux coating, or the polymer can be mixed with conventional fluxing material which mixture can then be coated on to a bare rod.  The polymer may also form an inner core in a cylindrical welding rod, and in addition the rod itself can be fabricated by dispersing polymer within the rod by mixing metal powder with the polymer and pressure-moulding to shape.  The consumable welding rod or filler wire may be brought into contact with the metal to be welded and heat applied thereto which heat decomposes the polymer to form an inert protective atmosphere about the weld area.  In submerged arc-welding the area for welding can be dusted with polymer powder or covered with a liquid dispersion of the polymer; the electrode being positioned so that it contacts the weld area under a blanket of polymer.  Polymer coatings on welding rods and filler wire can range in thickness from 0.1 -60 mils. Flux-polymer mixtures may be formed from ingredients such as lime or titania and flux coatings may contain from 0.1 -50.0% of fluorocarbon polymer. Metal-polymer mixtures should also contain from 0.1 - 50.0% of polymer with the polymer particles ranging in size from 5 - 700 microns.
