Abstract: 1414337 Overload protection circuit K TOTSU 22 May 1973 [22 May 1972 20 March 1973] 24438/73 Heading H2K [Also in Division B3] An electric motor driven screwdriver is provided with automatic stopping means comprising a circuit for detecting the presence of an overload current which lasts for longer than a certain set time and operating a relay in response to this overload to switch off the power to the motor, the power being subsequently restored by the circuit after a further set time. The circuit comprises a constant voltage circuit 14a formed by a Zener diode in parallel with a capacitor, and a resistor R L  in the supply lead 18b to the motor 16, and a transistor TR1 which senses the difference between the voltage across R L  and the voltage from the constant voltage circuit. In the event of overload, transistor TR1 conducts and causes transistor TR2 to turn on to pass current to relay RY1 in parallel with capacitor C2, which capacitor charges in a predetermined time dependent upon values of R6 and C2 to a voltage which actuates relay RY1. This time delay prevents operation of the relay due to a transient overload, but does cause operation due to the overload which occurs at the end of each screwing-up operation. The contacts 20 of relay RY7 close to pass current to relay RY2 which breaks the circuit to the motor and stops it. Transistor TR1 is then turned off as the voltage across the R L  drops to zero and after a further time dependent upon the vlaues of capacitor C2 and resistor R6 the relay RY1 is released to energize the motor again. A polarity reversing switch 24 is provided to reverse the motor, to undo screws or nuts, and so arranged that in the reverse connection the overload circuit is cut out.

Abstract: 519,624. Granular metallic products MERLE, J. M. Aug. 22, 1938, No. 24670. [Class 82 (ii)] [Also in Group III] A powdered or granular metallic product consists of particles of substantially uniform size and composition which have spontaneously crystallized from molten metal in a metastable undercooled state at a temperature closely below freezing point. They may be produced by allowing the metal to flow on to a linearly moving or rotating metallic surface, which cools it slightly below freezing point without solidification actually occurring, the undercooled metal leaving the surface in a thin film which then solidifies and breaks up into small particles. The operation may take place out of contact with air, to avoid oxidation, or in a suitable atmosphere for producing particles of a desired composition, for example in ammonia to produce nitrated particles. The particles may be projected through a coolant or against a cooled wall. The product may be employed, for example, for metallic paints and in powder metallurgy. Other materials may be introduced into the molten metal, for example, fine particles of emery, diamond dust, or carbides for producing an abrasive. Specifications 521,689 and 521,690, [both in Group XXII], are referred to. Reference has been directed by the Comptroller to Specification 469,244.
