Abstract: A device for fastening molded or extruded plastics parts, more particularly to an automotive body, by positive locking, comprising a base section joinable to the plastics part to be fastened and a retaining section adjoining the base section in a fastening direction. For forming a contact face, the retaining section protrudes beyond the base section perpendicular to the fastening direction. The base section and retaining section are made of elastically deformable material, at least the retaining section comprising a cavity. Such a device is characterized by the deformability of the retaining section being adaptable to the particular application in each case by relatively simple ways and means. The reason for this is that at least one elastically deformable partition is arranged in the cavity. The partition is configured as a through-hole extending in a normal direction perpendicular to the fastening direction and extends in a plane oriented perpendicular to the normal direction.

Abstract: A shutoff device is provided for pulverized coal burners of a pulverized coal furnace.

On the trailing side of the slide valve, the feed line is surrounded by an air receiver that is supplied with air. In the vicinity of the air receiver, an opening is provided in the wall of the feed line and can be closed off by a closure plate, which is synchronously actuatable with the slide valve such that in the closed position of the slide valve the opening is opened, and in the open position of the slide valve the opening is closed off.

Abstract: A leather covering piece for a vehicle interior lining comprises a leather piece and an intermediate layer connected with the leather piece. A hardenable mass is applied onto the intermediate layer or the leather piece. The hardened mass gives the leather covering piece such an inherent rigidity that it maintains a curved shape and can be inserted into an injection mold. The stacking of prefabricated leather covering pieces is also possible. The shape of the leather covering piece already corresponds to that of the finished product, in particular of the vehicle interior lining for which it is used. The leather covering piece is back-molded in order to obtain a stable carrier piece which gives the entire interior lining more stability.

Abstract: In a diode-pumped laser amplifier the inventive object is to increase the tolerance of the amplifier arrangement relative to variations of the input parameters significantly, so that fine-tuning is no longer necessary for guaranteeing the stability of the amplifier. Into a laser-active solid-state medium where a thermal lens of a strength which is different in orthogonal planes is generated in consequence of the irradiated pump radiation, a laser beam to be amplified is directed into the laser-active solid-state medium while being focused in the plane with a strong thermal lens, wherein a beam waist that is being generated lies in the area of the thermal lens. The laser amplifier can be used for amplifying the radiation of an oscillator.
