Title: Fluid pressure responsive diaphragm - has U=section annular region whose shape is adjustable by ring nut
Inventor: HEITMANN GERHARD
IPC: G01L7/08
Filed: 1976-08-04
Abstract: The fluid pressure-responsive diaphragm is secured at its periphery to a housing. A radially inner region of the diaphragm is secured to a disc (6). Between the periphery of the disc and the inside of the housing the diaphragm has a free annular region (11) of U-section which enables the disc to move axially relative to the housing. The periphery of the disc is in screw-threaded engagement with a ring nut (17). Turning of the nut causes it to move axially relative to the disc and so vary the radial extent of the U-section region. This varies the position of the bottom of the U-section and varies the effective area of the diaphragm.

Title: Sewing machine drive train - has an electromagnetic control for brake and clutch with adjustment for movement throw of each
Inventor: RIGHETTI FRANCO
IPC: D05B69/12
Filed: 1977-03-17
Abstract: The drive train to the operating parts of a sewing machine incorporates an electromagnetic brake and clutch system. The clutch plate is of a ferro-magnetic material, and is fitted with a friction cladding. It is mounted to the driven shaft with the help of flexible and sprung discs between the clutch plate and the shaft, so that the plate can slide axially along the shaft, while the flywheel on the drive shaft lies opposite the friction cladding of the clutch plate. A fixed electro-magnetic unit is energised to press the clutch plate against the surface of the flywheel. A rigid brake disc of a ferro-magnetic material and fitted with a brake lining, is fitted to the driven shaft. An electro-magnetic unit acts together with the brake lining and the limit surface attached to the housing, and flexible sprung discs between the housing and the electromagnetic unit, so that when it is energised the electromagnetic unit moves along the driven shaft and can be controlled to retract from the brake disc. A threaded ring has its thread engaged in the housing, and slides along the driven shaft under controlled rotation to bear against the limit surface and to bring it to or from the break disc. The design allows an adjustment to give the optimum gap between the brake lining on the brake disc and the corresp. surface while the electro-mtoro is running and the machine shaft is rotating.

Title: Processing the waste products of breeder fuel manufacture - reducing to smallest volume without formation of corrosive liquids
Inventor: MUELLER BURKHARDT DIPL ING
IPC: G21F9/06
Filed: 1977-11-30
Abstract: Solns. of the waste prods. arising from the mfr. of fuel or breeder material for nuclear reactors and containing ammonium nitrate together possibly with urea, are treated so as to break down these cpds. into oxides of nitrogen. The solns of waste are sprayed whilst being heated to a temperature in the range of 300-600 degrees C. During this process the ammonium nitrate is broken down to N2, NO, N2O, NO2, and H2O, with the urea forming NH3, and CO2. Before being released into the atmosphere or possibly recycled for further use, they are freed from the water vapour contained in the non-volatile radioactive materials. Used for dealing with the byproducts such as ammonium nitrate arising from the precipitation of uranium, thorium and plutonium cpds, which are sparingly soluble, from nitrate solns. of their salts. These solns. contain small quantities of radioactive materials, and in the case of reprocessed fuels, prods. of fission, so that the ammonium nitrate can neither be used as fertiliser nor dumped. The process handles the solns. of waste, economically and without environmental hazard, without the formation of corrosive solns., and with waste vol. reduced to a min.
