A centrifuge includes a power exchange rotor of efficient design which is provided with at least one channel member for guiding the flow of material therethrough from a first end exposed to a source of the material, which is a feed source in a rotor used as a feed accelerator and is material discharging from the bowl treating zone in a rotor used in power recovery. The channel is so formed as to c...

PURPOSE:To obtain a compact and reliable engine torque detecting method by regarding an addition value of a product value obtained by multiplying a change rate of an engine speed by a designated value and a detected transmission torque of a driving force transmission as an engine torque detection value. CONSTITUTION:A transmission control unit TCU 16 computes and stores an engine speed and its cha...

PURPOSE:To restrict the loss of discharged heat to a minimum value and improve the efficiency of a solar heat utilization system by a method wherein upon completion of a thermal collecting operation, a hot thermal medium remaining in the thermal collecting line is recovered into an auxiliary thermal accumulating tank and the heat is returned back to the thermal collecting line before a thermal col...

In hammer crusher rotors, the carrying body ends, in which the hammer axles, which run parallel to the axis of rotation of the rotor and reach beyond the length of the rotor, are mounted, are protected against wear by means of caps. Known caps make considerable demands on the precision of the shape of the cap web and of the receiving slots in the carrying bodies, do not protect the side surfaces o...

Binding assembly for a cross country ski boot, having a safety device comprising a hooking arrangement in which the forward end of the boot is retained, and lateral retaining, complementary engaging portions on the ski and in the sole of the boot. The hooking and lateral retaining devices are rigidly affixed to each other without intervening gap, and are releasable at least laterally about at leas...

Highly soluble complexes of 2-(4'-thiazolyl)benzimidazole are prepared using glycolic acid. The aqueous solutions prepared therefrom are stable and may be used for anthelmintic and antifungal purposes. Additional compounds, especially other fungicidal agents, may be combined for compositions of broad spectrum.

A shaped, non-opaque coated polycarbonate article having improved abrasion and chemical solvent resistance comprising a polycarbonate substrate having disposed on the surface thereof a non-opaque primer layer comprised of from about 25 to about 85 weight percent of a thermoset acrylic polymer and from about 15 to about 75 weight percent of at least one ultraviolet light screening compound, and dis...

A wheel bearing has inner and outer bearing rings each having a radially outwardly directed flange, and a plurality of rolling elements arranged between the rings. An annular seal has a support element affixed to the outer ring, the support element terminating in an annular elastic element of oil resistant material that is slidably engages the inner ring. A cover extends over the flange of the inn...

Heat resistant thermosetting prepolymers are prepared by reacting one or more methylated pyridines or pyrazines with one or more aromatic dialdehydes, and isopropenyl phenols. The prepolymers can be further reacted with bismaleimides to make prepolymers with lower cure temperatures and faster cure rates. The total number of methyl groups on the pyridine or pyrazine can vary from 2 to 4. The prepol...

A hydraulic cement mix including hydraulic cement, aggregate, sufficient water to effect hydraulic setting of the cement, and an additive comprising mixtures of alkali and alkanolamine salts of alkylarylsulfonic acids and alpha olefinsulfonic acids, and alkali and alkanolamine salts of fatty acids, and a nonionic component selected from polyethylene glycol derivatives and diethanolamine adducts of...

1. A sheet of transparent plastics material of high optical quality comprising a layer based on polyurethane having energy-absorbing properties, characterised in that the layer having energy-absorbing properties is formed essentially of a polyurethane obtained by reactive casting on a flat horizontal support of a reaction mixture of an isocyanate component of viscosity less than 5 Pas at 40 degree...

1. Dry powdery mixture for preparing foamed flat-shaped PVC-articles in two process steps containing a) emulsion-, suspension-, and/or block polymerisation-PVC, b) one or more foaming agents in an amount of 1 to 10% by weight, based on the PVC, c) utmost 150% additives and/or adjuvants, based on the PVC, d) 1 to 50% of a thermoplastic methacrylic acid ester-copolymer, based on the PVC, characteriz...

A process for producing a porous resin film containing a polyolefin resin as a main component, comprising melting a mixture of (A) 100 parts by weight of a polyolefin resin, (B) 0 to 50 parts by weight of a polyester-polyether type thermoplastic elastomer, and (C) a thermoplastic polyester resin having an instrinsic viscosity of not more than 0.5, the amount of the component (C) being from 25 to 9...
