Abstract: 1363485 Electro-erosion ATELIERS DES CHARMILLES SA 1 Oct 1971 [22 Oct 1970] 45703/71 Heading B3V An electro-erosion apparatus includes a base platen 2, a movable platen 5 slidable in a frame 6, 7 over a first distance and a work or electrode carrier 8 supported by guide means 9 or one of the platens 2, 5 and movable with respect thereto through a second shorter distance under the control of a servomechanism 12. In one embodiment, Fig. 1, the movement of a carrier 8 for the electrode 4 is controlled by a servomotor 12 in accordance with the erosion gap voltage. The shaft 21 of the motor 12, fixed to the carrier 8, is connected by a crank 14 to a frame 15 which is in turn connected by cranks 16 to screws 17 engaging nuts 19 on the platen 5. Guide rods 9 are positioned between the carrier 8 and its supporting platen 5 which is movable by jacks (not shown). Dielectric fluid is circulated to the gap by a pump 2a. In another embodiment (Figs. 3 and 4, not shown), the workpiece (1), e.g. a press die, is positioned on the carrier (8) carried by needle bearings (35-38) mounted on eccentrics (39-42) positioned at the ends of parallel shafts (33, 34). The piston-rod (46) of a pivotable jack (43) is connected to a crank (45) on the shaft (33), which is coupled to the other shaft (34) by linkage (47-49). Movement of the piston-rod (46) by the servomechanism causes the carrier (8) to be moved vertically. A platen (5) carrying the electrode (4) is movable by a piston and cylinder (27, 28<SP>1</SP>). A platen (2) on which the carrier (8) is mounted is movable horizontally to facilitate the positioning of the workpiece. In a further embodiment (Figs. 5 and 6, not shown), the workpiece carrier (8) is mounted on a frame (57) which is movable on inclined surfaces (64) by a jack (59) controlled by the servomechanism. Air cylinders (65) are positioned between the platens (2, 8) to compensate for differences in weight supported by the platen (8). The electrode is formed of two parts (4a, 4b).

A clamp for holding for upholstering the sidemember 68 of, e.g., an armchair, comprises a stand 14 having a ball and socket joint 16 lockable by a lever 20, a sleeve 22 connected tc the ball, a connecting member 26 arranged to be slidable, rotatable and fixable in the sleeve 22 and clamping means mounted on the connecting member. A support 60 slidably mounted in the connecting member 26 carries a shaped form 66 on which the workpiece 68 is carried. The con necting member 26 forms the lower arm of a C-frame 26, 28, 30, the upper arm 30 carrying a  bar 48 on which are mounted selected pins 52 for gripping the workpiece 68. The bar 48 is connected to the piston of a pneumatic cylinder 32 controlled by a hand-lever 38. In operation the workpiece 68 is placed on the form 66 with the prepared textile or like covering beneath it and hanging down as at 67. The hand-lever 38 is moved to its first position to apply partial pressure to the cylinder 32 to lower the bar 48 and grip the workpiece gently. Final adjustment of the covering is then made and full pressure applied to hold the workpiece firmly. The whole clamping-means may be tilted as required about the ball-joint 16 when this is released by the pedal 20, and when all work has been completed the hand lever 38 is moved to its third position to release the workpiece.

Abstract: 1,117,115. Commutator arrangements for dynamo-electric machines; inverting. RACAL COMMUNICATIONS Ltd. 10 Nov., 1965 [10 Nov., 1964], No. 45773/64. Headings H2A and H2F. [Also in Division G1 In a D.C. motor 5 an external commutator circuit 12, including two controlled rectifiers, responsive to the position of the motor shaft is connected between an electric power supply 11 and slip rings 7, 9 so as to supply the armature of the motor 5 with a continuously reversing current. The commutator circuit is controlled by a shaft position indicator 18 which comprises photo-transistors (24, 26, Fig. 2, not shown), blackened screens (42) and a visible or non- visible lamp source (40). The shaft of the motor is divided into non and light reflecting surfaces (32, 34 and 36, 38), the amount of light being reflected controlling the conduction of the photo-transistors. Each photo transistor gives two negative output pulses, (at 54, 56, Fig. 3, not shown), for one revolution of the shaft. These outputs (54, 56) are each transferred by a separate transistor circuit (Fig. 4, not shown), to control the conduction of silicon controlled rectifiers (78, 80, Fig. 5, not shown) of an inverter circuit which provides an A.C. output (at 72), for connection to the slip rings. Speed control.-The speed is adjusted by a variable frequency source 15 which controls the conduction of semi-conductor controlled rectifiers (100, 102, Fig. 6, not shown) forming the speed unit 14 connected to the slip rings. Alternatively these controlled rectifiers (100, 102) may be connected between the supply 11 and the commutator circuit 12, the rectifiers being controlled by pulses from the output of the commutator circuit. As the load on the motor varies so does the phase angle between the outputs of the commutator circuit and the variable frequency source 15 and this controls the conduction of the rectifiers (100, 102) so as to supply current to the armature to maintain the speed constant. A bridge circuit 16 returns energy from the output of the inverter circuit to the supply 11 when the semi-conductor controlled rectifiers (100, 102) are non-conductive. Starting.-The motor may be started by hand, or the S.C.R.'s of the inverter circuit may be connected directly to the slip rings by a switch which temporarily disconnects the inverter output transformer.
