Title: Tensioner for distributor chain in IC engines - contains plastics fitting and shock absorption elements
IPC: F16H7/08
Filed: 1975-01-22
Abstract: The composite tensioner consists of a shock absorbing member, and a connected thin fitting body with good abrasion resistance. The pre-fabricated fitting (1) is positioned in a mould, and a support member (2), consisting of a plastics with high friction characteristics, is inserted into it. An elastomer is injected into the mould under pressure to form the shock absorber (3), and also an adhesion between the support and the inner surface of the fitting. Adhesive may be applied to support and/or fitting, before the injection of the plastics. Fitting and shock absorber are cylindrical, and the centre of the shock absorber accommodates the end of a spring member. The fitting surrounds the shock absorber up to this point and the chain to be tensioned is guided along a generatrix on the surface of the fitting.

Title: Cyclic thermo chemical splitting of water - to form hydrogen using sulphur dioxide reaction with methanol in presence of a molten salt
IPC: C01B3/06
Filed: 1975-08-20
Abstract: In a cyclic thermochemical method for prodn. of hydrogen from water, SO2 is reacted with methanol in the presence of water in a molten mass of molten sulphate from which a corresp. pyrosulphate or bisulphate can be formed, the methanol giving methane or a methylated cpd. from which hydrogen is formed and the methanol is reformed, by sepn. of the SO3 from the molten salt mass and subsequent decompsn. of the SO3, SO2 and O2 are formed and the SO2 is recycled.
