Title: Electronic quartz crystal clock
IPC: G04C3/04
Filed: 1973-12-19
Abstract: 1453459 Electronic timepieces ITT INDUSTRIES Inc 19 Dec 1973 [22 Dec 1972] 58734/73 Heading G3T The frequency of oscillation of a balance wheel in a timepiece is stabilized by "locking on" to synchronizing pulses derived by a frequency divider F t , Fig. 2, from the output of a crystal controlled oscillator circuit O s . The balance, Fig. 1, includes a pair of discs 1 carrying permanent magnets 6 and counterweights 7, which magnets co-operate with a stationary coil system 8, including drive coil L 1  and control coil L 2 , and with a ferromagnetic member 10 (e.g. soft iron or nickel plated copper). The member 10 is increasingly effective on the magnet system toward the end of the oscillatory movement thereof to modify the natural period of oscillation and render the balance system anisochronous i.e. render the oscillation frequency more dependent upon oscillation amplitude. The free end of member 10 is shaped to conform to the arc swept by the magnets. The member 10 is displaceably mounted for fine adjustment. In Fig. 2, a drive transistor T 2  is rendered conductive by square wave pulses having a duty cycle of 0À5, from the divider. Movement of the magnets across coil L2 induces current pulses therein which render a transistor T 1  conductive during periods of coincidence of these pulses with synch. pulses which have a longer duration. Thus only sufficient drive current to maintain the balance synchronized with the divider output, will be passed through the coil L 1  and battery consumption is minimized. Alternatively the control circuit may include a mechanical switch operated by the balance wheel. The oscillation of the balance may be initiated by a lever tangentially engaging the balance wheel. Inherent frequency deviation of the balance introduced by the ferromagnetic member assists in the quick "capture" of the mechanical oscillation by the synchronizing signal the frequency of which corresponds to the natural frequency of the balance system.

Title: Sonically controlled vehicle
IPC: A63H17/39
Filed: 1979-03-20
Abstract: A sonically controllable toy vehicle includes a motor 4 and stands on two running wheels 3 and a scanning wheel arranged at the three corners of a triangle. A clutch mechanism includes a clutch gear 6 which is responsive to an audio command to move between a driving condition and a scanning condition. When the clutch gear 6 is in the driving condition it engages the gear 7 thereby causing the running wheels 3 to be driven and the scanning wheel to be held stationary. When the clutch gear 6 is in the scanning condition it engages the gear 8 thereby causing the wheel to scan in the range from +45 DEG to -45 DEG  from the straight- ahead position; the running wheels 3 remaining stationary. The vehicle has the facility that the clutch mechanism is triggered by a received audio tone above a prescribed level, and that once the clutch mechanism has been triggered, repeated triggering within a short time period thereafter will not have any effect. <IMAGE>

Title: Heating circuits
IPC: H05B3/34
Filed: 1979-04-17
Abstract: A circuit for an electric blanket or other heater comprises a heating conductor (2) connected between input terminals (5, 6), and a sensor conductor (3) and temperature sensitive medium (4) substantially co- extensive with the heating conductor. In the event of overheating, the impedance (Z) of the medium (4) drops from a relatively high to a relatively low value and/or it melts to permit contact of the conductors (2, 3) whereby the impedance (Z) will drop to substantially zero. A self-regulating PTC resistive element (7) is connected in series with the heating conductor (2) but disposed remotely therefrom. The element (7) is thermally coupled to resistors (9, 11), such that in the event of the medium (4) being overheated anywhere along its length the resultant current through the resistors (9, 11) will heat the element (7) so that it adopts and stays in a high resistance state, terminating the flow of heating current to the conductor (2). <IMAGE>

Title: Improvements in the manufacture of rubber products
IPC: C08L21/00
Filed: 1979-04-21
Abstract: White factice for incorporation into rubber compositions for the manufacture of very thin rubber products in such as bathing caps and hospital sheeting, is first mixed with a sufficient quantity of a powder to provide a powder coating on each and all of the ultimate particles, this mixing being achieved e.g. by means of rotatable paddle blades within a mixing container. The factice/powder mix is then transferred to a processing container in which the factice particles are subjected to the impacting action of e.g. an edged blade revolving at a high speed in excess of 1,000 r.p.m. The edge of the blade cuts through the particles in an atmosphere loaded with the powder which coats the freshly exposed surfaces and prevents them adhering together again. The factice is produced by sulphurisation of vegetable oils in known manner.
