Abstract: 1,230,002. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 19 July, 1968 [28 Aug., 1967], No. 34549/68. Heading H1K. [Also in Division H2] A device 47, Fig. 1, for indicating when the integrated energy of an electrical signal exceeds a predetermined value comprises a first heater H1 to which the signal is applied to generate heat therein, and a second heater H2, to which current is supplied, including a semi-conductor body thermally coupled to but electrically insulated from the first heater H1. The resistance of the second heater H2 varies with temperature in such a manner that regenerative heating occurs in the heater H2 when its temperature exceeds a certain value, and the thermal inertia of the heaters is such that heat is generated by the first heater H1 faster than it is dissipated from both heaters H1, H2. The second heater H2 preferably has a positive temperature coefficient of resistance, with an abrupt increase of resistance occurring at a transition temperature. Such a heater may have a negative resistance region in its current-voltage characteristic. In the embodiment the heater H1 also comprises a positive temperature coefficient of resistance semi-conductor body having an abrupt resistance increase at a higher transition temperature than the body of heater H2. A layer of insulating material 17 separates heaters H1, H2, and provides a thermal delay therebetween. A negative temperature coefficient thermistor TH1 is coupled to the heater H1 to detect temperature changes in the system due to heat generated in the first heater H1 or in the second heater H2 when the accumulated heat is sufficient to initiate regenerative heating therein. A circuit using such a device for protecting an induction motor against current overload (see Division H2) includes, in series with the motor, a current sensor device 45, Fig. 3, comprising a negative temperature coefficient of resistance semi-conductor body 65 situated between a central electrode 63 and a cylindrical shell electrode 65. When the load current passing through the shell 65 between electrodes 71, 73 exceeds a certain value the resistance of the body 65 decreases abruptly, resulting in a rise in current between the terminals 67, 69, one of which is connected directly to the first heater H1, Fig. 1, of the integrating device.

Abstract: 1,264,682. Strut-type suspensions. FICHTEL & SACHS A.G. 30 July, 1969 [30 July, 1968], No. 38235/69. Heading B7D. [Also in Division F2] A piston-cylinder shock absorber has either (as shown) a subsidiary piston 8 attached to the rod 6 of the main piston 7 or an annular fitment 108, Fig. 3 (not shown), in the cylinder loosely surrounding the piston-rod. In either case, the piston-rod is thereby given an additional restraint against lateral displacement at a point between the piston 7 and the piston-rod seal 15. This minimizes bending of the rod when a radially directed force A is applied to the rod. Such forces arise particularly in steerable front wheel suspensions, and the unit shown is designed for such use. It consists of a hydropneumatic shock absorber combined with a suspension spring 1 and a wheel axle 13. The piston 8 or equivalent cylinder fitment (108) itself contains valved and/or unvalved ports. In the case of the piston 8 these ports may be holes extending through the piston or axial grooves in its periphery (Figs. 5 and 6, not shown). End stops.-The subsidiary piston 8 of Fig. 1 is associated with a by-pass groove 16 in the cylinder 4, which groove terminates short of the cylinder end. The piston 8 may carry a resilient buffer element 19, Fig. 4 (not shown), or a valve element 32 in the piston may be engageable with the seal 15. All these features co-operate to provide an end-stop system.
