Abstract: 1,172,433. Magnetic tape transport. CONSOLIDATED ELECTRODYNAMICS CORP. 21 Feb., 1967 [21 Feb., 1966], No. 8257/67. Heading G5R. [Also in Division G3] A magnetic tape is driven past a head 40 or 48 by a capstan 44 servo-controlled in response to a signal recorded on the tape, the tape being engageable on the opposite side of the head from the capstan by means 70-74 for filtering out tape velocity fluctuations above the upper frequency limit of the servo system, e.g. 200 c/s. As shown, the tape is engaged with a flywheel 70 by rollers 72, 74 coupled to an actuator 88. During recording, a signal from oscillator 62 is recorded in one track of the tape via head 42 and is compared with a signal generated by a pick-up 56 and serrated disc 54 to actuate the motor control 64. During playback, the control signal is played back via head 46 and replaces the signal from pick-up 56. The supply and takeup spools 12, 14 are driven by motors 16, 18 controlled by sensors 26, 30 (e.g. potentiometers) operated by loop-forming rollers 20, 32.

Title: Improvements relating to relay mechanisms for controlling fireextinguishing apparatus
IPC: A62C35/60
Filed: 1931-03-18
Abstract: 371,128. Automatic release hooks. PYRENE CO., Ltd. and HUNTER, J. N., Great West Road, Brentford, Middlesex. March 18, 1931; No. 8330. [Class 89 (ii).] Relates to relay mechanism for releasing suspended weights or stressed springs for operating fire - extinguishing apparatus, and particularly applicable to the automatic or distant control of such apparatus; and comprises a train of pivoted, interlocking levers normally held from turning movements by a spring-loaded ratchet and pawl. The lever 2 at one end of the train of levers 2, 12, 10 is formed with a hook 1 to support the weight (not shown). The lever 10 is held from turning movement about its pivot under action of a spring 21 by means of an arm 9 normally lying at right angles to the lever 10 and carried by a gear wheel 8. The latter is urged to rotate, to free the lever 10, by a spring 20, but is held from rotation by its engagement with a pinion 7 fast with a ratchet wheel 6, the latter being locked by a pawl 4. When the pawl is disengaged, the spring 20 is free to move the arm 9, but the arrangement is such that the pawl may slip several teeth of the ratchet accidentally without causing release of the weight. The lever 12 exerts its locking thrust on the lever 10 in the direction of the pivot of the latter, so that the force due to the weight is not transmitted to the ratchet. The impulse for disengaging the pawl from the ratchet is derived from air bulbs placed in an area to be protected. In case of fire, the air expands, and moves a diaphragm 14 carrying a pin 19 in engagement with the tail of the pawl. Alternatively, the pawl may be disengaged by manual or electrical means. In a modification, the pawl is disengaged by a lever which is moved by a spring when released by the movement of an impact-operated pendulum.

Filed: 1952-04-02
Abstract: 698,458. Inductances. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 2, 1952 [April 5, 1951], No. 8388/52. Class 38 (ii). A coil 1, which may be a corrector coil with variable inductance for correcting the non- linearity of the saw-tooth current in the deflection coils of a television receiver, having a ferrite core 3, is mounted in an insulating housing 7 together with a permanent magnet 13 which premagnetizes the core 3. This magnet 13 is mounted in a non-magnetic cylinder 11 which is rotatable so that while the magnet 13 and core 3 remain parallel and opposite, their distance apart and consequently the degree of saturation of core 3 is variable. It is shown that as the magnet 13 is moved from the position nearest the coil the intensity of premagnetization varies approximately directly with the angle of rotation of cylinder 11. The magnet 11 should be at least as long as the coil 1.
