Title: Circuit arrangement for the speed control of electric motors

Filed: 1972-11-02
Abstract: 1398793 Automatic control of speed INTERNATIONAL STANDARD ELECTRIC CORP 2 Nov 1972 [2 Nov 1971] 50543/72 Heading G3R [Also in Division H2]  An A.C./D.C. series motor M is connected to an A.C. supply through a triac T1 which receives triggering pulses from trigger diode D 1 when capacitor C 1 has charged to the required level. The back e.m.f. generated by the motor when the triac switches off at the end of a half cycle is used to set the conductive state of transistor T2 and thus, by shunting resistor R3, the resistive component of the negative half cycle charging circuit. During a positive half cycle the capacitor is charged through the circuit including R and D3 and the charging current is thus adjustable. The amplitude of the back e.m.f. used to set transistor T2 is proportional to the motor load current at the moment triac T 1 switches off and so the arrangement provides for automatic control of speed. Preferably a field effect transistor is used.

Abstract: 1,126,032. Strain gauges, electrical. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 17, 1966 [Nov. 29, 1965], No.50593/65. Heading G1N. Dynamic strain on a workpiece (e.g. a power transformer casing) is detectable by a transducer having two pointed sapphire styli 11 (Fig. 1) cemented to one face of a Piezo-electric leadzircon-titanate ceramic strip 9 held by the styli on an aluminium foil diaphragm 3, through which the styli protrude. The diaphragm is held in place on the end of a cylindrical brass casing 1 filled with cellular polyurethane slightly compressed so that it forces the diaphragm taut causing the styli to be supported in the position shown. When pressed against the workpiece, the styli form indentations in the surface thereof by which they are then located. Relative movement between the styli due to strain on the workpiece, produces an electrical output from the strip 9 by virtue of its ferro-electric properties, only during the stressing movement, and therefore only dynamic stresses produce an output. In the case of a workpiece subjected to alternating forces, e.g. at a frequency of 100 c.p.s. and multiples thereof the output voltage will be alternating. The transducer may be connected to a switched filter unit, whereby output at selected frequencies only can be measured. There may be three styli having tips in a common plane arranged at the apices of a right angle triangle and fixed to two strips 9, to detect strains in two mutually perpendicular directions.
