Title: Improvements in or relating to electric braking systems
IPC: B60T13/74
Filed: 1928-05-19
Abstract: 290,678. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). May 19, 1927, [Convention date]. Electric and magnetic.- Electrically propelled vehicles or trains of vehicles are provided, in addition to electrodynamic braking means, with brakes which are applied by springs or other power storage medium and withdrawn by current taken from the operative conductor. The arrangement is such that the brakes are applied by breakage of a coupling between two vehicles. Brakes applied to the motor armature or other shafts by springs c connected to levers b are taken off by magnets f supplied from the main conductor t<1> and are held off by detents e controlled by magnets e which receive current either from the conductor t' or from a battery k. The current supplying the magnets e and relays g which control the circuit of the release magnets f is supplied thereto by conductors x, y running throughout the train: To ensure that these conductors are connected together only at the rear end of the train, this connection is taken through a seg. ment o on the travelling disection drum, a conductor z, and a switch pin r<1> which is moved to its outer operative position by energizing a winding r in series with the directional reversing windings which receive a high current at the moment of switching over the direction reversing lever. The switch pins r<1> at adjacent ends of the vehicles are pressed in by the coupling halves pressing against each other. With the relay i energized and the dead-man handle p depressed the relays g and magnets e are energized by current from the main conductor t' through the conductor x the segment o of the travelling disection drum of the rear car, conductor z, switch r<1>, conductor y and in the case of the relays g, contacts h controlled by the detents d. The magnets f are thus energized to take off the brakes and the detents d are operated to lock the brakes in this condition and to break the contacts h thus de-energizing the magnets f. If the current in the conductors x, y is interrupted as by the opening of the contact at the handle p, by operation of an emergency handle m, m<1> or by the breakage of a coupling the detent magnets e are de-ener. gized and the brakes applied. If the main current fails the detents e receive current from a battery k through the relay i, to ensure the run until the next station is reached.

Abstract: 399,924. Control of two motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Mohler, F. ; 15, North Ferry Street, Schenectady, New York, U.S.A.) May 28, 1932, No. 15213. Convention date, May 28, 1931. [Class 38 (iii).] Motors 14, 15 drive respectively reducing rolls 11, 12 for operating on strip steel 10 and a winding reel 13, and they are controlled so as to accelerate in unison and to maintain a constant tension on the strip both when rolling and when stopped. The strip is threaded between the rolls 11, 12, the motor 14 being started by depression of button 34 which causes closure of line contactor 21. This contactor maintains itself closed independently of the button 34, and also causes closure of line contactor 22 and subsequent closure of accelerating contactors 33, 32. The motor 14 is stopped by depression of button 35 when the end of the strip reaches the reel 13. After securing the end of the strip to the reel, the motor 15 is energized in a similar manner by depression of button 38, but its circuit contains a stalling resistance 40 so that it can maintain the required tension on the strip. A repeat depression of button 34 causes both motors to accelerate in substantial unison by reason of their armatures being connected in parallel through conductor 41. The speed of both motors is adjusted by linked field rheostats 29, 30. Automatic tension control is effected by a current sensitive vibratory relay 44 controlling the field of the motor 15. Rheostatic braking of each motor is produced when the associated contactor 21, 25 opens, and of motor 15 during threading by closure of a button 61 so as to produce a jogging action.

Filed: 1932-05-30
Abstract: 401,768. Furnace walls. MORGAN CRUCIBLE CO., Ltd., and WALKER, J., Church Road, Battersea, London. May 30, 1932, No. 15313. [Classes 51 (i) and 51 (ii).] In a hollow air-cooled furnace wall the inner panel is built up of refractory tiles 4 laid edge to edge and cemented together, and is so supported from the outer panel that it can expand and contract relatively thereto in all directions in its own plane. The tiles are preferably made of silicon carbide, and some or all have integral struts which rest on ledges 10 projecting from the outer wall. The struts are of skeleton formation so as not unduly to obstruct the flow of air between the panels and they may be loosely tied to the outer wall to prevent bulging of the inner panel. In one form, Fig. 4, an horizontal foot 8 of the strut takes behind an upstanding projection 12 of the ledge 10, and it fits loosely thereon to allow slight horizontal movement of the tile. In other forms the tie is made by hook or ring bolts which pass behind and encircle respectively the feet 8. Two forms of strut are shown in Figs. 2 and 3, and other forms are described in which the horizontal and inclined members 6, 7 are not in vertical alignment. The strut may also take the form of a vertical V, or an horizontal V with an end foot. The under faces of the ledges 10 are preferably curved or chamfered to deflect upflowing air on to the inner panel, and when the outer wall is of metal and the ledges are formed by angle irons, curved plates may be fitted for the same purpose. Openings may be formed in the inner wall for the supply of air to the furnace by notching the edges of the tiles, and a relatively large free air space may be provided in the vicinity of these openings by arranging a course of tiles such as shown in Fig. 2 in inverted position.
