A motor vehicle having at least two live axles is driven by an engine having an output shaft which is transverse to the direction of travel of the vehicle. That engine is succeeded by a change-speed transmission having shafts which are parallel to the output shaft of the engine. The change-speed transmission drives one live axle via a spur gear train and drives the second live axle via a first ang...

A moulded article is prepared by impregnating a body of glass fibres with an aqueous solution of a phenolic resin, raising the temperature of the mixture to gel the resin, then cooling the mixture to retard further polymerisation during handling and storage prior to heating of the mixture in a mould to complete curing.

According to the method, a fluorine-containing gas compound which is stable to room temperature is brought to a decomposition temperature and is then supplied to the surface to be proofed. The invention is particularly applied to the fabrication of tanks (3) of polyethylene intended to contain hydrocarbons such as tanks for motor vehicles.

A "limited slip" differential (10) employing transfer gears (23, 24) drivingly connected to output gears (18, 19) such that upon relative rotation of the output gears (18, 19) the transfer gears (23, 24) pump a hydraulic fluid through a circuit to inhibit relative rotation between the output gears (18, 19).

In a fixed bed, under 5-150 bar, the solid fuel are gasified by a gasifying-agent which contains oxygen, steam and/or CO2. After gasifying, the residues of incombustible mineral are drained out. The powdery and fine fuel are spurted into the bottom of the bed with the carrier flow. The size of powdery and fine fuel is about 6 mm. and, at least of 50% (weight) of them are smaller than 3 mm. The car...

A reduction gas is produced containing mainly carbon monoxide and hydrogen from carbonaceous or hydrocarbon-containing material by means of thermal energy from at least one plasma generator in a separate gas-generating shaft. The gas after sulphur separation and temp. adjustment, is conducted to a reduction shaft containing the oxidic material. The partially spent reduction gas withdrawn from the ...

The utility model relates to an electromagnetic brake with a rotating disk with permanent magnetism, which is used for forming a fast starting and stopping motor. The center of a rotating disk is provided with a permanent magnetism body; a sliding bush can rotate along with a shaft and freely slide in an axial direction on a rotary shaft; a magnetizer and the sliding bush form a closed magnetic ci...

A combustion method wherein the fuel is burned in a primary combustion zone (10, 11, 12) under reducing conditions and sulfur captured as alkaline sulfide. The reducing gas formed is oxidized to combustion gas in a secondary combustion zone (2, 3) which is then separated from solids containing alkaline sulfide in a separation zone (13, 14). The separated solids are then oxidized in a solids oxidat...

The element for decoration comprises a crystal glass bar, which is formed with a cavity that extends through the bar along its longitudinal center line and is open at both ends, and a wire which extends through the cavity and serves to attach the bar.

The "Sealed Differential Assembly" is a component relating transmission systems of automotive vehicles, specifically differential assemblies. Its denomination intends to establish a distinct identity when compared to the traditional similar component. They differ one from the other essencially because the new component is fit to operate on transmission systems whose final reduction is carried out ...
