Title: Remote control mechanism for toys
Inventor: NAZABAL ALBERTO PEREZ
IPC: A63H30/04
Filed: 1967-10-13
Abstract: 1,207,809. Remote-controlled toy. A. P. NAZABAL. 13 Oct., 1967 [3 June, 1967], No. 46854/67. Heading A6S. [Also in Division H4] A toy remotely controlled by radio signals from a transmitter which is operated by the user comprises a receiver which operates an on-off switch of a motor 20 powered by a battery and coupling means for transmitting drive from the motor to control the steering and traction, the receiver having an electromagnet 4' which displaces an operating rod 5" when a pulse of radio signals is received. The toy e.g. a car has a cycle of operations, e.g. forward motion, turning right and left, reverse motion and stopping, and is arranged to be moved to the next position of the cycle when a radio signal is received. On receipt of a first signal, rod 5" displaces member 3" so that its portion 29 is displaced downward so that spring 7' causes tooth 31 of clutch unit 2" to engage a similar tooth in pinion 1" and at the same time to close contacts 6 and start motor 20. Drive is transmitted to pinion I" which rotates the clutch 2" which remains stationary after a single revolution. Simultaneously cam pinion 8' advances part of a revolution and maintains contacts 6 closed. Also cranked shaft 11' rotates part of a revolution and displaces a steering rod 32 rearwards so that the front wheels turn right. As the cranked end portion moves rearwards and upwards a gear selection crank 13 is released and its hooked end 36 engages selector pinion 12' with pinion 1" to engage forward gear. A further radio signal causes portion 29 to be displaced downwards. The cranked end portion moves to the top and forward gear selection is maintained. A further radio signal causes the wheels to turn left as the cranked end portion moves forwards and downwards and a fourth signal causes the cranked end portion to move downwards and rearwards so that the gear selection crank 13 displaces gear selection pinion 12' which engages pinion 14 to transmit reverse drive to the output shaft 15. A final fifth pulse causes the front wheels to turn to the right with reverse gear engaged the cam 10' permitting contact 6 to open thus stopping the toy.

Abstract: 1,099,815. Pure fluid amplifiers. PRINTING PACKAGING & ALLIED TRADES RESEARCH ASSOCIATION. Oct.31, 1966 [Nov.10, 1965], No.47689/65. Heading G3H. [Also in Division F2] A fluid logic element comprises a body having a passage with a port 2 provided with a Piezoelectric bender element 6 arranged to regulate the flow of fluid in accordance with electric potentials applied to the element. The element is provided with electrodes 7 and 8 and clamped as a cantilever to a plate 1 forming a cover for a fluid amplifier having an inlet 4, an outlet 3 and a vent 12. When the element 6 is deflected to open the port 2 the main jet flow is diverted from a port 3 to a vent 12. A shallow groove may be provided in the plate 1 beneath the element 6 to reduce the air forces opposing deflection of the element 6 and thus improve the frequency range of the device. Alternatively, a small jet 35, Fig. 5A, may be provided to assist bending of the element 6 and to increase the controlled air flow. The port 2 may be formed in a separate member in adjustably screwed engagement with the plate 1 and provided with a conical face for engagement by the element 6. In Fig. 6A an element 61 provides a differential output at ports 57 in accordance with applied electric potentials. The outputs are also controlled by a pair of control jets 53, 53'. The Piezo-electric elements may be of lead zirconate titanate.

To equalize the positive and negative halfcycles in an A.C. welding circuit, the negative half-cycles are shortened by a thyristor 7, and/or the positive half-cycles may be fed from a variable higher voltage such as an additional secondary winding 2. The thyristor is controlled in synchronism with the supply by a voltage across a resistor 81 or a current transformer (21 Fig. 6, not shown) which may saturate at low welding currents. In an alternative arrangement, the thyristor 7 is quenched by a commutating circuit (Fig. 6, not shown). The transformer primary winding(s) may be tapped.
