Title: Improvements in electrical spark machining devices
IPC: B23H1/02
Filed: 1955-02-04
Abstract: 782,443. Cutting by spark discharge. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Feb. 4, 1955 [Feb. 22, 1954], No. 3447/55. Class 83 (4). [Also in Group XXXV] In an electro-erosion machining device the sparks between an electrode 1 and workpiece 2 are produced from an alternating potential U which is controlled by a ferro-magnetic switch device 3 so that unidirectional current discharges are produced between the electrode and workpiece without the alternating potential having to be rectified by conventional means. The device 3 comprises a closed magnetic circuit 3c, made of thin strips of an alloy having a high initial magnetic permeability and a sudden saturation, on which is wound a main winding 3a carrying the alternating potential, and a biasing winding 3b supplied with low voltage direct current from a source 7 through a self-inductance 6. Current passes continuously through the coil 3a due to ionization of the spark gap and the biasing produced by the coil 3a produces voltage peaks through the main coil 3a such that the positive peak is of greater potential than the negative peak. Only the positive potential peaks are sufficient to spark across the gap between the electrode and workpiece and therefore only these unidirectional positive current pulses occur in the discharge circuit. The supply circuit from the alternating source U may include an energy accumulator system constituted by a delay line comprising condensers 4a, 4b, 4c and inductors 4d, 4e, 4f, together with a self-inductance coil 5, the accumulator system thus producing voltage peaks across the points A and B greater than and 90 degrees out of phase with those of the source U. The delay line 4 may be replaced by a condenser or condensers or by a reactive impedance; the coil 5 may also be omitted. A matching impedance 8 may be used for matching the. impedance of the spark gap with that of the remainder of the circuit; this matching impedance may be replaced by a transformer. In another embodiment using a three-phase supply, Fig. 4, a motor 9a drives an alternator 9b which produces a frequency ranging from 100 to 10,000 cycles per second at 50 to 1500 volts. This current passes through a transformer 10 and each phase then passes through a separate ferro-magnetic switching device 3. All of the switching devices are supplied with direct biasing current from a generator 7 driven by the motor 9a, which generator also supplies exciting current to the alternator 9b; the biasing current may be varied by a resistance 11. The circuit also includes accumulator systems 4 and a matching impedance device 8.

[Class 80 (ii)] [See also Group XXXIV] In a servo-brake mechanism wherein three plates of a clutch are mounted on a single shaft on which the two outer plates are secured to turn therewith, the intermediate plate is loosely mounted on the shaft and is provided with a peripheral portion which projects beyond the peripheries of the other two plates so that it may be engaged by a gear drive coupled to the road wheels or the engine or is connected to the brake rigging. As shown a central disc 12 with friction rings 17 is loosely mounted on a shaft 4 and is driven from the engine by a pinion 15 or chain. A disc 7 is keyed to the shaft 4 and an opposed disc 7a is slidable on the reduced portion of the shaft 4. A drum 9 is connected by cable to the brake gear. The slidable disc 7<a> is operated by a plunger 19 and pivoted lever 21 and slackness in the gear is taken up by a pawl 26 pivoted to a link 25 operating between stops 27, 28. During normal operation the pawl remains between two teeth of the rack 24 but if wear occurs the pawl slips one tooth and restores the gear to its normal clearance. The slack adjusting gear may comprise a serrated key in the boss 5a, the pawl being housed in the key slot. The discs 7, 7a may be driven from the engine.
