Abstract: The invention relates to aluminum-tin (Al-Sn) base bearing alloys and bearing materials made by applying said alloys to a backing steel sheet by pressure welding. In an alloy according to the invention the coarsening of tin particles and the lowering of the hardness under high temperature conditions may be kept relatively moderate so that the wear resistance as well as the fatigue strength of the alloy are improved. Bearing alloys according to the invention may be used for the bearings of internal combustion engines in which spheroidal (nodular) graphite cast iron is generally used for crankshafts.

Abstract: Apparatus for translating rotary to linear motion using cylindrical means in the form of a shaft or cylinder with helical grooves, usually having a thread profile.For obtaining good efficiency and large gear ratio, i.e. small linear movement per revolution, the apparatus has been made up from an outer cylinder (1) with a rear transverse portion (5) and a forward outer opening (3) through which an inner cylinder (11) is unrotatably displaceable.The inner cylinder (11) has on its inside a helix groove (12) or thread, in which at least one profiled roller (30, 32, 40) with circular ridges (33) engages. The roller or rollers are eccentrically disposed at one end of a drive shaft (23), rotatably but axially undisplaceably mounted (8) in the outer cylinder (1) at its other end. When the shaft (23) rotates, the rollers (31, 32, 40) roll or follow in the grooves (12) of the inner cylinder (11) and displace the inner cylinder in the outer cylinder.

Abstract: A drive unit for a compressor which is used in a heat pump. The drive unit includes a fuel-injection internal combustion engine which is coupled with the compressor and a starter associated with said engine and is fed from multiphase electric power supply lines. The starter is connected to the electric power supply by means of a switch. The starter is constructed as an electromagnetic drive motor having a stator and a rotor secured to the engine crankshaft and serving at least partly as a flywheel. The coil windings on the stator are fed current from the power source.

Abstract: A process for the preparation of a two-functional-group-containing terpenoid having the general formula: ##STR1## in which n is an integer of from 1 to 5, R represents a hydroxymethyl, formyl or carboxyl group, and A represents the hydrogen atom, or a 2-tetrahydropyranyl, benzyl, methoxymethol or methoxyethoxymethyl group comprising the oxidation with a microorganism belonging to the genus Nocardia.

Abstract: A solenoid valve having a valve body and a magnetic head with a chamber arranged between a pair of magnetic cores. A movable armature is provided in the chamber and has a sealing member movable therewith between open and closed positions relative to a passageway through one of the magnet cores. A spring is provided for biassing the armature and, accordingly, the associated sealing member toward one of the two positions thereof. The force of the magnetic field generated by the electrically energizable magnetic coil encircling the magnet cores is greater than the return force of the return spring.

Abstract: An apparatus for molding spherical bodies from a semisolid stick wherein said semisolid stick is extruded through a nozzle; a sensing unit disposed in front of said nozzle detects it to thereby send a signal to a cutter; said cutter, upon receiving said signal, is actuated to cut said stick in fixed lengths; the sticks thus cut are received in a rotatable mold; and said rotatable mold allows said cut sticks to travel along the inside of a molding passage which comprises the rotatable mold and a fixed mold disposed opposite thereto.

Abstract: An adjusting device for determining the thrust force of a ski binding capable of movement along the longitudinal axis of a ski, which thrust force is adapted to urge the heel binding into engagement with the heel of the ski boot. The adjusting device includes a rail having a slide slidably mounted thereon. Both the rail and the slide have support surfaces for engaging, respectively, the toe and the heel of a ski boot. A scale having indicia thereon is provided on the rail and the position of the slide relative to the rail is indicated by an indicator juxtaposed the indicia on the scale. The ski binding is then adjusted to a corresponding scale notation on the ski to thereby set the ski binding at the desired position and, consequently, the thrust force at the desired level.
