Title: Shock absorbers
Inventor: LAWSON DEREK TOM
IPC: F16F9/06
Filed: 1948-05-04
Abstract: 649,794. Hydraulic shock absorbers. ELECTRO-HYDRAULICS, Ltd. May 4, 1948, No. 12258. [Class 108(iii)] In a shock absorber of the kind within which there is a cooperating plunger and piston and which comprises inner and outer cylinders and three chambers, two of which are damping chambers of equal diameter separated by a ported diaphragm forming part of one of the cylinders, the third chamber being spring-controlled, valve means is provided between one of the chambers and the third chamber which reduces communication therebetween when the shock absorber closes too rapidly. In Fig. 1, a diaphragm 10 carried by a tubular member 9 rigid with a surrounding concentric cylinder 1, divides an inner cylinder 4 into liquid chambers A and B. A chamber C contains compressed air or, alternatively, deformable solids, e.g. a coiled or rubber spring. A valve 15 controls flow through an annular space between the member 9 and a piston head 8 rigid with the inner cylinder 4, and may be biassed into opening position by a light spring (not shown). A valve 16 carried by the member 9 has apertures 18 which register with larger apertures 11 in the diaphragm 10. In operation, on compression, air is compressed in chamber C while liquid damping occurs through the apertures 11, the valve 16 remaining open. On both rebound and rapid compression movement of the shock absorber, the valve 15 is forced on to its seating and prevents liquid passing to chamber C. On slow compression the valve 15 remains open due either to gravity or to the biassing spring. Increased damping occurs on rebound due to seating of the valve 16. In Fig 2 the diaphragm 10 is rigid with the outer cylinder. Liquid chambers E and D are bounded respectively by the end of the inner cylinder 5 and a piston 22, carried by a piston rod 9 rigid with the inner cylinder 5. Passages 23 controlled by a valve 15 afford communication through the piston 22 between the chamber E and a third chamber F. The valve 15 closes as before to prevent communication between chambers E, F on rebound and rapid compression but remains open on slow compression movement of the shock absorber.

Abstract: 842,117. Electric tests. LICENTIA PATENTVERWALTUNGS-G.m.b.H. April 18, 1957 [April 23, 1956; Feb. 21, 1957], No. 12737/57. Drawings to Specification. Class 37. In circuit breaker testing in which separate high current and voltage sources are used, to maintain the arc up to the most favourable breaking point, the frequency of the high current source is reduced so that the duration of its half wave corresponds at least to the duration of the arc in the breaker when operated at the nominal frequency. The position of the half wave of the high current is so adjusted that it passes through its zero valve at the instant the passage through zero of the last half wave of the arc current is enputed when operated with nominal frequency. The amplitude of the high current wave is so adjusted that the energy produced over the disconnecting distance is the same as that produced by the several half waves at nominal frequency. In the care of breakers in which the arc produces a gaseous quenching medium the opening of the breaker may be delayed with respect to the start of the half cycle so as to produce the required pressure.

Abstract: 1,64,803. Automatic temperature control. HITACHI SEISAKUSHO KABUSHIKI KAISHA. March 26, 1965 [March 31, 1964], No.12905/65. Heading G3R. To control the temperature of the rotor of a rotary electrical machine so that it is maintained constant or prevented from exceeding a maximum value, a temperature variable semi-conductor resistor having a positive or negative temperature coefficient and imbedded in the rotor, is connected to affect the Q of a series or parallel tuned circuit, the coil of which is located on the rotor surface so that it passes near a fixed coil once per revolution of the rotor. The fixed coil is arranged in a bridge or constant current circuit supplied with A. C. from an oscillator through a buffer amplifier. The periodic coupling affects the current through a resistor, arranged in the bridge or constant current circuit, to an extent dependent on the temperature. The voltage across this resistor, after transistor or valve amplification, rectification and smoothing, is applied to a Schmitttrigger circuit which controls the load on the machine e. g. by variation of field or rotor resistance or by a relay interrupting a supply in an on-off manner. Alternatively the interruption may be arranged to be permanent if a maximum permissible temperature is exceeded. Design formulae to ensure maximum sensitivity of control are given. In a modification, several temperature detecting circuits are arranged on the rotor and control is effected in dependence on the highest temperature detected. Alarms or indicators may be provided.
