The second tubular end portion comprises a socket, which contains ...

The utility model discloses a solid fuel containing charcoal, which is particularly suitable for a chafing dish. The solid fuel containing charcoal is a cylinder or a sphere which is provided with at least one through hole and composed of 30 to 80 of charcoal, 20 to 70 coal (weight %) and a small quantity of caking agents. The solid fuel is easy to ignite like the charcoal, but the solid fuel has ...

The invention relates to a method of controlling a PFBC power plant in the event of an operational disturbance affecting a turbine unit driven by the plant, for example a load drop out, said plant comprising a bed vessel (12) enclosed within a pressure vessel (10) and surrounded by compressed combustion air, said bed vessel containing a bed (22) of fluidizable particulate material, and a gas turbi...

A clutch type disc brake is provided with a housing, at least two axially displaceable brake discs (14) arranged in the housing at least four friction surfaces (12, 15) out of which in each case two are arranged on both sides of one brake disc (14), and an actuating device having at least two actuating cylinders (6) with actuating pistons (7a, b) arranged therein, which actuating device is arrange...

Disclosure is made of a method of curing the polyepoxide resin binder component of polyepoxide based syntactic foams of high density. Ketones are employed to reversably block primary amine groups on polyamine curing agents during the initial curing. As the cure progresses, the block is removed to complete the cure. The result is a moderation of peak exotherms generally associated with the cure, in...

An oriented p-phenylene sulfide copolymer film is derived from a copolymer comprising repeating units of the following formulae (I) and (II), the amount of repeating units (I) being from 70 mol% to 90 mol% of units (I) and (II): wherein X represents the following structural formula (III), (IV), (V) or (VI): Y represents H, C1-C5 alkyl, a nitro group, phenyl, C1-C5 alkoxy or a h...

A computer system for providing self-service access to job vacancy information has a central control computer in which such information is stored under job category. The job categories fall under job headings which are indexed at remote terminals (14). The latter have coin- freed mechanism and, upon insertion of money or money's worth, display a selected heading and the job categories thereunder. ...

An automatic transmission is changed from the highest gear ratio to the next lower gear ratio upon depressing the brake pedal after the accelerator has been released to cause the automotive vehicle to begin a coasting operation as long as the engine speed is higher than a predetermined engine speed. As a result the engine speed increases, resulting in an increase in the time period when the engine...

A non-volatile, acid acceptor which is soluble in polyolefins is added to a film grade polyolefin resin composition to prevent gel streaking/pinstriping or corrosion during film extrusion processes. The acid acceptor has a molecular weight greater than 180 with less than 5% by weight volatiles at 180 DEG C as measured by a thermal evolution analysis.

This disclosure describes the treatment of cellulose acetate butyrate contact lenses which are rendered hydrophilic by contacting said lenses with a treating agent which increases the hydrophilicity of said lenses. The treating agent is ammoniacal salt, alkali-metal hydroxide, strong mineral acid, benzene sulfonic acid, alkali metal borohydride or organometallic compound.

A process for the production of polyamide mouldings, characterized in that a polyamide melt is extruded through nozzles to form strands, which at a temperature of from 25 DEG C. below to the respective polyamide softing point in a ratio of from 1:1.5 to 1:8 are stretched and granulated, and the granulate is worked-up in a known manner to produce injection mouldings.

The impact strength of containers made from foams of aromatic olefins such as polystyrene and poly-(para-methylstyrene) is improved by the addition of a small amount e.g., 2 to 25 weight percent of a polyethylene such as linear low density polyethylene. Meat trays made of such foams can be processed in automatic packaging equipment and exhibit reduced damage, such as cracking, in processing.
