Abstract: Upgrading coke quality of coals by adding a pitch-like product with a softening point (K-S) of 90.degree.-160.degree. C. to the coal. The additive is obtained by treating finely divided coal or other carbon containing raw material with hydrocarbon solvents derived from coal and petroleum and then removing 2-20% of the light boiling components of the highly aromatic pitch-like product.

Abstract: A process is described for the modification of wood and wood products by heat treatment in a closed, heatable vessel, wherein the water content of the starting material is controlled to be no higher than 10% by weight.

Abstract: Bituminous binders are disclosed which contain at least one silane and show excellent improvement of adhesion. The bituminous binder containing silane is manufactured by heating The bituminous binder to a temperature of 120.degree.-230.degree. C. and stirring in the silane. All known silanes can be used as the silane. The resulting compositions can be used for the production of street surfacings, industrial floors, floorings, building protective paints, roof coating masses, undercoatings for motor vehicles and rail vehicles, and cable covering compounds.

Abstract: An image-forming apparatus comprising an original-support plate for placing an original document thereon, a photosensitive member support stand disposed opposite to, and beneath, said original-support plate for placing a photosensitive member thereon, a charging-exposing unit for forming a latent electrostatic image corresponding to the original document on the photosensitive member, said charging-exposing unit being mounted between the original-support plate and the photosensitive member support stand for transverse reciprocation, and a power driving source for moving said charging-exposing unit reciprocally. The charging-exposing unit includes a mechanism for feeding the photosensitive member. During the return movement of the charging-exposing unit, the photosensitive member transfer mechanism acts on the photosensitive member placed on said support stand to move the photosensitive member incident to the return movement of the charging-exposing unit.
