Title: Improvements in or relating to hydropneumatic suspension systems for vehicles
IPC: B60G11/26
Filed: 1961-11-20
Abstract: 940,887. Adjusting vehicle height. REGIE NATIONALE DES USINES RENAULT. Nov. 20, 1961 [Dec. 30, 1960], No. 41511/61. Heading B7D. An automatic levelling device for a hydropneumatic suspension system comprises a reservoir 1 supplying fluid to a pump (Fig. 1, not shown) feeding a distributer 5 built into the reservoir 1 and containing a valve 27 (Fig. 3) which delivers fluid through an outlet 33 to a suspension cylinder supporting a suspension arm carrying a road-wheel or permits return of fluid from the suspension cylinder to the reservoir 1 depending on the pressure prevailing in the suspension cylinder. The reservoir 1 comprises a cylindrical body connected to the distributer 5 and contains a piston 14 urged downwardly by a spring 15 and connected by an invaginated diaphragm 12 to the wall of the reservoir to define a variable-capacity chamber 24. A sealed flexible bellows 18 secured to the piston 14 carries a closing plate engaging a bell crank 21 co-operating with a rod 22 carrying the valve 27. Fluid is supplied from the chamber 24 to the pump and is fed under pressure to the distributer 5 through an inlet 34. If high pressure exists in the suspension cylinders due to increased loading a piston 28 on the rod 22 urges the valve 27 to its closed position against the force exerted by the bellows 18 through the bell crank 21 and fluid is delivered to the cylinder via a non-return valve 35 and the outlet 33. If, on the other hand, pressure is low in the suspension cylinder due to reduced load the bellows 18 acts on the rod 22 through the bell crank 21 to move the valve 27 to the right so that fluid flows from the suspension cylinder through grooves 37 in the piston 28 to the chamber 24, and the fluid delivered by the pump to the inlet 34 is returned to the chamber 24.

Title: Low background radiation detection
IPC: G01T1/178
Filed: 1964-10-15
Abstract: 1,070,657. Photo-electric beta-radiation detectors. BECKMAN INSTRUMENTS Inc. Oct. 15, 1964 [Oct. 28, 1963j, No.42054/64. Heading G1A. Fig. 2 shows an arrangement for shielding and compensating for background radiation in the betaradiation measurement of a sample 111, in which the beta-detector 112 is surrounded by a gammaradiation lead shield 114 which in turn is surrounded by a cosmic ray detector 113. The two detectors are connected to an anti-coincidence circuit so that a pulse registered by the betadetector may be blanked off if a pulse is received simultaneously by the cosmic ray detector, both pulses being due to the same background radiation. The arrangement largely eliminates errors due to cosmic-ray secondary radiation created in the shield by external cosmic rays. For example, the cosmic ray E produces a secondary ray E', which may or may not register in the betadetector due to the low efficiency of beta-detectors to such rays. However a blanking pulse is always provided whether the secondary ray registers or not since the original cosmic ray E must first register in the outside cosmic ray detector. This is an improvement on the system in which the shield surrounded both detectors. The beta-detector may be a geiger counter, gas proportional counter, scintillation counter, spark counter or solid-state detector. In a practical embodiment Figs.3 and 4 (not shown) a neutron moderator shield may surround the cosmic ray detector.
