By providing a photographic original plate on which an original picture image and a light-shielding mask are formed, two identical pictures can be formed by exposing a sheet of photosensitive material with the original plate placed thereon and repeating the procedure after rotating the original plate 180 degrees about a point which is located outside of the picture image and the light-shielding ma...

A vehicle position indicator system utilizing microwave detection of nearby vehicles is disclosed. The system includes two slot receiver antennas formed in the longitudinal extremities of a bumper of a vehicle and a slot transmitter antenna formed in the bumper between the two slot receiver antennas. The slot transmitter antenna is driven by an amplitude modulated signal, and the slot receiver ant...

An anti-rattle or biasing member is positioned between the torque receiving member of an automotive disc brake and the brake shoe backing plate urging said backing plate into an anti-rattling engagement with said torque carrying member.

The waste products arising from cleaning and desulphuration of the flue gases from coal-fired power stations are used to form underground stopping and/or backfill and gallery consolidating materials by mixing the waste products in the form of gypsum and filter ash or boiler slag with wet or dry calcium chloride from the flue gas washing stage and preferably adding binders, hardeners and cement, th...

The invention relates to a bracing apparatus for sheet-metal parts, in particular pressed, stamped and/or forged cutlery parts, which are to be machined on their contour. The apparatus has at least one workpiece rest and at least one clamping device which presses the workpieces against said rest and has at leat one retaining part to be placed onto the workpieces. The object of the invention is to ...

Disclosed is a process for modifying accumulated cross-linked polymer in an apparatus used for the production of a vinylaromatic compound, comprising optionally softening the polymer with an organic solvent; precipitating the polymer with a light, polar non-solvent for the polymer and expanding the softened polymer by bringing the softened polymer in contact with steam whereby the polymer is conve...

1. An aqueous binder dispersion for the vulcanization of rubber onto substrates stable under vulcanization conditions, consisting of a halogen-containing polymer in latex form polyfunctional aromatic nitroso compounds masked polyfunctional isocyanates pigments, carbon black, foam inhibitors, emulsifiers and other auxiliaries, characterized in that the halogenated polymer is a copolymer of a haloge...

An improved polyurethane lacquer for coating an elastomer containing at least one polyfunctional aromatic nitroso compound as an adhesion improver and optionally, lacquer-nonreactive spacer particles.

It is taught that rubber can be vulcanised by means of sulphur using a polyether and at least one conventional accelerator, the concentration of the conventional accelerator being below the range customary hitherto, i.e. below 1.3 % by weight, based on the rubber. Particularly suitable are block polyethers comprising ethylene oxide and a 1,2-alkylene oxide having 12 to 20 carbon atoms. It is also ...

The present invention relates to a process for producing foam plastic mouldings in which foamed, closed-cell plastic particles with a closed surface, preferably based on polystyrene, are brought into contact with a composition producing foamed, rigid or elastic epoxy foams, which fills the interstices between the plastic particles with foam, and foam mouldings produced in this manner, preferably i...
