Title: Grinding apparatus for a suspension of fibres for paper manufacturing
IPC: D21D1/22
Filed: 1981-08-05
Abstract: A housing is equipped with a set of grinding tools and a rotor equipped with a second set of grinding tools. One of the parts carrying the grinding tool set is moveable in relation to the other part, which may be constituted by the rotor, in axial direction of the rotor and can be adjusted by a piston-and-cylinder unit impingeable with a pressurized fluid medium, preferably compressed air. The compressed air infeed into the piston-and-cylinder unit is accomplished by a compensation force regulator controlled as a function of the pressure of the stock suspension within the internal compartment of the housing and a grinding force regulator controlled independently of the compensation force regulator in accordance with a set value signal infed by a control line. The pressure force exerted upon the one moveable part therefore is the resultant of a first force component influenced by the compensation force regulator and corresponding to a compensation force which compensates the pressure force of the stock suspension and a second force component influenced by the grinding force regulator and adjustable in accordance with a predetermined grinding force. Thus, there prevails a substantially constant grinding load which is practically independent of possible changes of the stock suspension pressure within the housing.

Title: Buried zirconium layer
IPC: G21C3/20
Filed: 1983-04-25
Abstract: A nuclear fuel element (14) for use in the core of a nuclear reactor is disclosed it has a roll-bonded fuel can (17) with a substrate (21), a non-alloyed zirconium barrier (22) metallurgically bonded to the inner surface of the substrate, and an inner layer (23) metallurgically bonded to the inner surface of the zirconium barrier.

Title: Helical gear pump.
IPC: E21B43/00
Filed: 1983-07-19
Abstract: A helical gear pump 18 has a rotor 44 rotatably mounted about the axis, the drive shaft 22, and at least two stators 42.1, 42.2, 42.3 of resilient material mounted operatively in series around the rotor 44, at least one of the stators 42.2 having an outer wall which is unconstrained against radial inward movement along a portion of its length. Delivery pressure in a clearance space 48 around the outside of such unconstrained wall of the stator 42.2, compensates at least in part for the internal pressure exerted radially outwardly tending to expand the stator 42.2. Such an arrangement, makes it possible the provision of less initial interference between rotor 44 and stator 42.2 thereby resulting in the use of a lower starting torque and making it possible for such pumps when fitted in boreholes, to be hand driven or to be driven by a windmill. Such an arrangement also makes possible the effective pumping of hot liquids, by having initial interference between the rotor 44 and the stator 42.2 than would have been necessary with a conventional rotor.

Title: Process for producing sterile air for medical use, and apparatus for carrying out this process.
IPC: A61M16/00
Filed: 1984-01-26
Abstract: Apparatus for producing sterile air suitable for being administered to intensive-care patients in hospitals using atmospheric air. The medical-grade air is free of gaseous contaminants and germs, at a cost substantially lower than when such air is prepared by mixing pure nitrogen with pure oxygen. Atmospheric air is compressed through at least one dry-piston compressor, condensing water vapor out of the compressed air through expansion into a buffer tank, filtering out dust particles down to micron size in a prefilter, drying the air through an adsorption desiccator unit and eliminating gaseous contaminants through an adsorption-desorption unit. A second dust filter is provided for trapping any dust released from the adsorption units. Biological contaminants, such as viruses and bacteria, are eliminated by flowing through a sequence of three biological filters of the coalescence type, and finally through a cold sterilizing unit. The desiccator unit and the unit for the elimination of gaseous contaminants contain a compound of metal oxides with silicates K, Na and Mg, the amount of this compound being larger in the elimination unit than in the desiccator unit.
