IPC: H01F7/06
Filed: 1968-11-18
Abstract: 1,232,229. Linkwork. V. DUPREE. 30 Sept., 1969 [18 Nov., 1968], No. 54630/68. Heading F2K. [Also in Division H1] An electrical actuator e.g. simulating muscular action comprises six pantograph connected arms having anchor points A, B of which a centre arm 1 carries dual electromagnets 2 and flanking arms carry electromagnets 3 disposed so that in the closed state (Fig. 1) the poles at opposite ends of the electromagnet pairs register adjacently. On energization of the electromagnets for expansion, like poles are adjacent and repel, so that the device expands and draws the anchor points together. If the electromagnets are energized as shown in Fig. 2 the open position is stable, and the device is biased to close on reversal of energization. The arms need not be rigid, and the device is then provided with a restoring spring. In a modification (Figs. 3, 4, not shown) the anchor points are at the apexes of two triangular frameworks based on opposite poles of three electromagnets of which one is disposed to slide in the gap between the outer pair, thus closing the anchor points on energization with like poles at corresponding ends of all three electromagnets and opening them on energization with unlike poles at corresponding ends of centre and outer electromagnets.

Abstract: 1,264,777. Clutch control. SAB BRAKE REGULATOR CO. Ltd. 24 Aug., 1970, No. 40619/70. Heading F2L. An. automatic slack-adjuster for a clutch release linkage comprises a spring 20 which transmits axial thrust between an input element 16 and an output rod 17 until the force transmitted is sufficient to disengage the clutch whereupon the spring 20 yields to release a nut 18 which adjusts the slack in the linkage if the clutch engaging force is attained before a predetermined axial travel of the rod 17 has occurred. In Fig. 3, an input rod 11 is fast with axially slidable sleeves 16, 21, 22 and the spring 20 normally holds the nut 18 against an inclined surface of the sleeve 21 to prevent rotation of the nut 18. If the clutch release force is attained before the nut 18 engages an axially slidable non-rotatable brake sleeve 24 the spring 20 yields and the sleeve 21 moves away from the nut 18 which is thus permitted to rotate to adjust the slack in the linkage. The screw-thread connection between the nut 18 and rod 17 is such that the nut will rotate under the axial force of the spring 20 unless otherwise restrained. In Fig. 4 (not shown), the input rod (11) and sleeve (16) are replaced by an hydraulically-actuated piston (30). In Fig. 5 (not shown), the sleeve (21) is extended and the inclined surface thereon engages the end of the nut (18) remote from the spring (20) whilst the brake sleeve (24) engages an intermediate shoulder (28) of the nut (18). In Fig. 7, an hydraulically-actuated input piston 61 is fast with a sleeve 67 having a flange 68 which is normally held engaged with a flange 66 of a nut 64 by the thrust transmitting spring 70. When the transmitted force is sufficient to disengage the clutch the spring 70 yields and the flange 68 is disengaged from the flange 66 and thereafter the sleeve 67 acts through a bearing 79, distancepiece 78, sleeve 80 and a flange 65 on the nut 64 to transmit axial movement to the output rod 63. During initial axial movement of the input piston 61 and output rod 63 an additional sleeve 71 is rotated by a pin 72 carried by a fixed housing 62 engaging a helical slot 73 in the sleeve 71. When the predetermined axial travel of the rod 63 is attained the pin 72 engages a straight slot 74 in the sleeve 71. A one-way coil spring clutch 77 connects the sleeve 71 with the. sleeve 80. During clutch release movement the sleeve 71 overruns the sleeve 80 and during clutchengaging movement the sleeve 71 drives the sleeve 80 through the one-way clutch 77. If during clutch re-engagement the pin 72 enters the helical slot 73 before the spring 70 releases the sleeve 80 from the flange 65, the nut 64 is rotated to take up slack in the linkage. Fig. 6 (not shown) is similar to Fig. 7 but the bearing 79 and distance-piece 78 are omitted whilst the sleeve fast with the input piston is extended to act directly on the sleeve driven by the one-way coil-spring clutch.
