Abstract: 1,162,807. Friction-type shock-absorbers. O. E. PETER. 19 Dec., 1966, No. 56836/66. Heading F2S. A friction-type shock absorber comprises a frusto-conical shaped piston 2 which is carried, with radial clearance, on a shock transmitting- member, e.g. a bolt 6 between a bolt head 7 and a locking ring 8, and which works in a correspondingly conical inner surface of a cylinder 1. As applied to a safety belt for an automobile a pin 5 on a closure disc 4 secured to the cylinder 1 by a locking ring 9 is fixed to the vehicle body and the outer end of the bolt 6, which extends through a closure end plate 3, is fixed to the safety belt, not shown. Tensile stress on the bolt, due e.g. to a collision, causes the piston 2 to move in the conical bore of the cylinder 1 in the direction of the arrow, the cylinder being expanded with its elastic limit and the piston being radially compressed. The shock absorber is re-set by forcing the piston 2 back into its original position. The piston 2 and cylinder 1 are preferably made of an aluminium alloy with a hard metal coating on their contact surfaces and the piston 2 can be slit, or slotted axially.

Filed: 1971-12-09
Abstract: 1356686 Steam generator COMBUSTION ENG Inc 9 Dec 1971 [10 Dec 1970] 57335/71 Heading F4A A vertical shell and tube steam generator has means to maintain stable fluid circulation by adjusting the rate of water supplied to the evaporator region in response to changing operating conditions. Tubes 28, Fig. 1, conduct the heating medium through the outer shell 12 between inlet and outlet chambers 22, 24, and feedwater, entering at 38, passes via ring manifold 40 to an annular downcomer reservoir 36 defined by a cylindrical baffle 34. The hydrostatic head in reservoir 36 induces circulation up through the central evaporation chamber 26 past the heating tubes 28. Tubes 58 in the reservoir 36 effect communication with the evaporation chamber and have inlets 62 dispose at different heights, Fig. 3. As operating conditions change the water level 46 in the reservoir moves between the low and high load limits 46a, 46b, and the level will determine the number of inlets 62 available to admit water. The rate of water flow to the evaporation chamber can therefore vary with operating load. Horizontal baffles 52 in the steam space 48 conduct the steam across tubes 28 for superheating.

Filed: 1972-12-20
Abstract: 1412305 Semiconductor devices PIONEER ELECTRONIC CORP 20 Dec 1972 [1 Jan 1972] 58874/72 Heading H1K A magnetic head is manufactured using a ferrite substrate 11 (Fig. 1) on which are vacuum deposited one or more indium antimonide Hall elements 13 and associated electrodes and leads and between them and the edge of the substrate a pair 15, 16 of resistive elements parallel connected between external connections 14a to to the Hall elements. Element 16 may be connected directly to connections 14a via leads 17b instead of, as shown, through the Hall elements. The substrate is assembled with ferrite tips in a head module (Fig. 2, not shown) which is then placed in a grinding apparatus with connections 14a connected to a measuring circuit the output of which is detected and fed to a switching circuit which controls the grinding speed by altering the pressure with which the grinding wheel bears on the head. No change in resistance across connections 14a occur until the grinding reaches element 15. Then the resistance increases progressively as the element is ground away whereupon the grinding speed is reduced. No further change occurs until element 16 is reached whereupon the resistance rapidly increases and becomes infinite when the element is completely removed causing the switching circuit to terminate the grinding process.

Title: Self-adjusting contition-responsive control circuit
IPC: H03K17/955
Filed: 1972-12-22
Abstract: 1388440 Proximity switches WAGNER ELECTRIC CORP 22 Dec 1972 59479/72 Heading G1N A proximity switch includes means to generate a signal which varies continuously about a reference level determined by the monitored parameter and an arrangement for automatically adjusting the reference level to compensate for slow changes in the monitored parameter extraneous factors such as humidity and temperature. In a capacitive proximity switch negative going output pulses from a relaxation oscillator 300 are fed via A.C. amplifier 400 to switching circuit 500 which if the magnitude of the pulses from the oscillator are within a predetermined limit is biased to be conductive so that load controlling relay 700 remains unenergized. A tap 406 on resistor 404 of the amplifier allows input signals to be applied to emitter-follower 800 which feeds the pulses to a second switching circuit 900 which becomes alternately conductive and non-conductive as the magnitude of the pulses becomes greater and smaller respectively and relay 1100 becomes alternately de-energized and energized. When relay 1000 becomes de-energized a charging path is closed from battery 1210 via relays 1100 and 700 to capacitor 1208 so that as the positive charge rises thereon the effective drain-source resistance of MOSFET 322 increases and the magnitude of the positive going pulses developed across resistors 306, 308 increases. Thus the negative going pulses of the output of the oscillator 300 decrease so that switching circuit 900 becomes non-conductive and relay 1100 energized whereby the charging path to capacitor 1208 is opened and a discharge path through resistor 1204 closed. As the charge on capacitor 1208 decreases so the drain source resistance decreases and the oscillator output increases in magnitude again to cause switching circuit 900 to become conductive again. In this manner the circuit hunts about a reference level at a rate determined by the RC constants of the charging and discharging path of capacitor 1208 and thus slow variations in capacitance between antenna 312 and ground due to humidity and temperature merely cause the circuit to adjust its reference level. When a person or object comes into proximity with antenna 312 the increase in capacitance results in the output pulses of the oscillator 300 becoming less negative to a degree that switching circuit 500 is biased by voltage across capacitor 506 to be non-conductive and relay 700 energized. Simultaneously the charging/discharging path of capacitor 1208 is interrupted by the opening of the lower contact pair of relay 700. If the body moves away the circuit begins to hunt again. The apparatus may detect changes in resistance (not described).
