Title: Improvements in and relating to the control of direct current electric traction motors
IPC: B60L7/04
Filed: 1936-05-15
Abstract: 471,615. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd., MARDIS, P. L., and BINNEY, E. A. May 15, 1936, No. 13800. [Class 38 (iii)] Non-regenerative braking.-For the power and rheostatic braking control of traction motors two independent controllers are employed, and electrical interlocking means prevent a transition from braking to power conditions until both controllers have first been moved to the " off " position. Upon pedal operation of a power controller 12, line contactors 9 are closed to connect the motor 1 to the supply, contactors 5 are closed in turn to cut out armature resistance 4 in steps and one or more contactors 8 are closed to weaken the powerful series field 2. The supply for the operating coils 9a, 5a and 8a of these contactors includes in series normally closed contacts 10b of a braking contactor 10, and contacts 13a of the braking controller closed only when the braking controller is in the off position. An addition set of contacts 12b on the controller 12 first energizes and then de-energizes the operating coils 7a, 11a, of contactors 7 and 11, to insert and control an auxiliary shunt-excited field-winding 3 for starting. When the braking controller 13 is operated it first opens contacts 13a to interrupt the supply for the operating coils of the power contactors 9, 5, and 8. It then closes contacts 13b in turn first to energize the coil 10a of the braking contactor 10 which connects some or all of the resistance 4 across the motor armature, with additional resistance if desired. It then connects the field winding 3 and strengthens it. A part of the field 2 may be included in the rheostatic braking circuit. The braking contactor 10 in addition to de-energizing the power contactors by opening the contacts 10b closes contacts 10c to prepare or complete a holding circuit for itself over contacts 12b of the power controller. Thus so long as the power controller is operated the contactor 10 is maintained, and to transfer from braking to power conditions the power controller must be returned to the off position to de-energize the contactor 10, and re-establish the supply for the power contactors over contacts 10b. A contactor 14 which interrupts or weakens the field 3 has its coil 14a connected to respond in the event of abnormal voltage.

Title: Improvements in and relating to shoe sticking presses

Filed: 1932-05-13
Abstract: 381,511. Boot making machines. MICHALK, O., 10, Kroenerstrasse, Freital, Dresden, Germany. May 13, 1932, No. 13865. Convention date, June 19, 1931. [Class 17 (i).] Sole-laying.-In a shoe cementing press, particularly of the multiple type, the clamping of the shoe in position and the inflation of the press pad are successively performed by a single manually operated valve, a valve operating member being actuated against an opposing force abruptly increasing at the transition point. A frame a supports a number of presses each having an inflatable pad C<1> and a clamping lever d<1>, the presses rotating about a centre. A cam e is carried by a piston rod f<1> in a cylinder supplied with pressure fluid by a pipe f <11> under the control of a piston valve k having two necks m, m<1> and at its lower end, longitudinal grooves mll. The valve is depressed by a head k<1> supported by two springs l, l<1> the latter being shorter than the other. The topmost position of the valve is determined by a collar k<11> normally engaging a pivoted stop n which can be moved by a lever o to allow the valve to rise further. A port i leads to a pressure supply, a port h to the inflatable pads, via a distributing valve on the axis of the machine, and a port pleads to the atmosphere. In operation, when a new workpiece has been inserted in the press at the operator's position, the head k<1> is depressed until the resistance of the shorter spring is felt. The neck m<1> then admits fluid to the cylinder f and the clamp d is forced down on to the shoe. Further depression of the head k<1> opens the cylinder f to exhaust, allowing the cam e to descend, and admits pressure fluid to the pad. If it is desired to release a shoe which has been badly positioned, its press pad may be deflated by depressing the lever o, tripping the stop n and allowing the grooves m<11> to connect with the pipe h.

D to be stropped is drawn back edge foremost between the stropping-surfaces, which are pressed together by pressure of the hand on the strips B, or the fingers on a portion of the backing exposed by an aperture in the strips; both sides of the edge of the blade thus are stropped simultaneously.
