Title: Improvements in or relating to transducer apparatus
IPC: G11B21/12
Filed: 1956-02-07
Abstract: 791,785. Magnetic recording and reproducing apparatus. COMPTOMETER CORPORATION, [formerly FELT & TARRANT MANUFACTURING CO.]. Feb. 7, 1956 [Feb. 18, 1955], No. 3773 / 56. Class 40 (2). In a transducer apparatus, a magnetic transducer carriage is mounted for transverse movement and pivotal movement between a transducing and non-transducing condition, driving and driven members engage to impart transverse movement to said carriage, and means pivoted on the carriage separate the said members while the carriage is moving the transducer to a non-transducing position. The transducer A is supported on an arm 12 mounted on a two-armed carriage 18, 19 free to slide and rotate on a rod B. The carriage 18, 19 also supports two U-shaped pivotal members 33, 44 free to rotate on carriage 18, 19 within restricted limits but held against sideways movement thereon. The member 33 is free to move along a, lead-screw F but is restricted against rotational movement by an extension 32 and plate 37 secured thereto which embrace the leadscrew F. During a transducing operation, Fig. 1, a spring 49 connected between members 33 and 44 holds the tongue 46 of a U-shaped bracket 48 on member 44 in engagement with the lead-screw F through a slot 39 in plate 37 and causes the carriage 18, 19 to traverse the rod B. A tab 47 of the U-shaped bracket 48 bears at the same time on the plate 37 and limits the movement of the tongue 46 towards the lead-screw F so that the contact force between the latter is independent of the weight of the transducer A. When the transducer is lifted by the projection 14, the tongue 46 is disengaged from the lead-screw F and a detent member 28 on carriage 18, 19 latches behind the extension 32 and the carriage is held above the record cylinder C in which position it may be freely moved along rod B.

Title: Improvements relating to protective circuit arrangements
Inventor: WALKER ALEC HERVEY BENNETT
IPC: H02H3/08
Filed: 1959-02-04
Abstract: 883,349. Protective arrangements. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Feb. 4, 1960 [Feb. 4, 1959], No. 3898/59. Class 38 (4). [Also in Group XXXVII] A protective circuit comprises two parallel oppositely poled conductivity-controlled semiconductor circuit paths, each path having a blocking characteristic in the reverse direction and a breakover voltage for conduction in the forward direction, control means for applying triggering signals to render the paths conducting, and current-responsive means to inhibit the application of the triggering signals when the current taken by a protected load exceeds a predetermined overload value. In Fig. 1 the parallel paths are provided by rectifier 9, 99 and semi-conductor diodes 5, 55 each of which conducts in the forward direction of the associated rectifier when triggering pulses are applied by an associated pulse generator 4 or 44 under the control of a flip-flop device 6. Under normal conditions the paths conduct on their appropriate half-cycles so that A.C. is supplied from a source 1 to a load 2. When the current to the load 2 exceeds the predetermined value, a current-sensing device 7 supplies a signal to the device 6 which then acts to cut-off the pulse generation so that the supply to the load is interrupted. Restoration of the supply to the load 2 may be effected by manual control of the device 6. In an alternative arrangement, Fig. 2 (not shown), the protective circuit is connected in parallel with the load and is normally non-conducting. When the predetermined load current value is exceeded, the protective circuit is rendered conducting and places a short-circuit across the load to cause the tripping of a highspeed circuit-breaker. In either embodiment the rectifier-semi-conductor combination in each path may be replaced by a three-electrode semi-conductor device which has a permanent blocking characteristic in-the reverse direction and a breakover voltage in the forward direction controllable in dependence on the voltage applied to a control electrode, Figs. 3 and 4 (not shown).
