Inventor: SUTARUK ALEX
IPC: F16D35/02

Abstract: A fluid coupling device is disclosed of the type including an output coupling member (13), a cover (35), a valve plate (29) separating the fluid reservoir chamber (33) from the fluid operating chamber (31), and an input coupling member (11) rotatably disposed in the operating chamber. Valving (41) controls the flow of fluid between the reservoir and the operating chamber in response to variations in a condition such as temperature. The input member has a front face (55) adjacent the valve plate and a rear face (57) co-operating with the adjacent surface (59) of the output member to define interdigitated lands and grooves (61,63). The input member defines a plurality of fluid passages (71) permitting direct axial communication of fluid between the front face and the lands and grooves. This direct flow into and out of the lands and grooves is effective to reduce substantially the time required to achieve full engagement and full disengagement of the coupling. The invention is also effective to feed fluid into the lands and grooves during engagement, to increase the overall torque capacity of the coupling.

Abstract: The invention relates to a process for the production of gas-transport pores in catalytic materials for the electrochemical conversion of gaseous reactants by making them water-repellent with an organic polymer and is based on the object of designing such a process in the manner that an improvement of the electrochemical properties of the catalytic material is achieved. For this purpose, it is intended that the catalytic material be treated with a solution of polysulphone or polyvinyl chloride in an organic solvent, the organic polymer content of the solution being between approximately 1 and 6% by weight and approximately 1 to 5 parts by volume, preferably approximately 2 parts by volume, of the solution corresponding to 1 part by weight of the catalytic material. The process according to the invention is especially suitable in the case of silver and nickel catalysts for fuel elements operated with air. <IMAGE>

Abstract: The carcass of the used tyres includes not only rubber parts (5, 6) and reinforcing materials (4) but also bead cores (1-3), in the form of steel cable rings, arranged in the tyre beads. To recover the bead cores for re-use in new pneumatic tyres, the carcass parts of the tyre beads containing the bead core are separated from the used tyre and, after mechanical removal of the reinforcing materials (4) and the majority of the rubber parts (5, 6), the rubber surround remaining on the bead core is detached chemically or electrotechnically, after which the surface of the bead cores is cleaned and the surface of the cleaned bead cores is chemically or galvanically treated. If appropriate, the outermost wire layer (3) of the bead cores is removed and replaced by a new wire layer. The electrotechnical treatment comprises electrically heating up the separated bead parts.

Abstract: A recording medium having a reflective layer (6) on a transparent support (1) can be obtained by physical development of a layer of physical development nuclei (2) in the presence of metal ions. The ions can for instance migrate from a colloid layer of a metal salt (6). The association of developed nuclei, after physical development, results in a reflective layer with metal atoms obtained by reducing the metal ions, whose reflectivity is reduced on irradiation through the transparent support. The manufacture of such recording media does not require vacuum system.

Abstract: Fine ferrite powder is produced by adding an ammonium oxalate solution to a solution containing ferrous ions and divalent metal ions to co-precipitate oxalates. After separating, washing and drying the co-precipitated particles, they are calcined for several hours at a relatively low temperature (eg 200°C) before completing the calcination at a higher temperature (eg 800°C). The particles are then vibro-energy or ball milled and dried. 
     Dense ferrite blocks can be made from the ferrite powder. by pressing the powder into a mold, sintering the molded ferrite and then isostatically pressure compacting it at a temperature of 1200°C and at a pressure of 2.00 x 10 8  Pascals. Dense nickel-zinc ferrite blocks produced in this manner are particularly suitable for the manufacture of magnetic transducer heads.
