Title: Road wheel
IPC: B29C45/14
Filed: 1988-09-29
Abstract: The invention relates to a road wheel (1) with a plastic rim body (2), consisting of a rim disc (2c) with a rim (2b) and profiled outer face (2a) arranged thereon, which has undercuts (2d1, 2d2) for receiving an annular preform or insertion ring (3a) which forms the rubber tyre (3) of the road wheel (1) and on its profiled underside (3b) also has undercuts (3c1, 3c2) and an outer face (3d) behind which injection moulding can take place at a temperature of 220 to 240@C in order to form the tyre (3). The road wheel (1) is provided with a customary hub (4) and a sheath (5). With the proposed method according to the invention for producing the road wheel (1), the high injection heat of the plastic for the rim body (2) is used to obtain a permanent connection by melting on its profiled outer face (2a) and subsequent fusing with the profiled underside (3) of the preform (3a). The preform (3a) is injection moulded independently at approximately 190@C and after cooling is inserted into the injection mould for the rim body (3a). <IMAGE>

Title: Process for the final storage of bound waste materials
Inventor: PETRI JUERGEN DR ING
IPC: G21F9/16
Filed: 1988-10-04
Abstract: The process for final storage of bound waste materials uses materials known per se based on lime, quartz and silica components, if appropriate with addition of cements or gas-forming compounds, these materials being used in their not yet exhaustively reacted preliminary state as a suspension mixture in liquid, pasty or gel-like form and being charged into the cavity of the final store repository in which natural or artificial sources of energy are utilised for introducing heat into the suspension mixture and for its polymerisation on the basis of hydrothermal synthesis. By means of selection of the composition of the suspension mixture, the energy consumption of the mixture or the energy delivery in the mixture, based on the time up to hardening of the mixture, is controlled.

Title: Ceramic foam body mfr. - includes forming dense inner wall cladding to determine flow path of medium flowing through body
Inventor: HERMANSKI WERNER
IPC: F01N1/24
Filed: 1990-09-12
Abstract: To form a ceramic foam body, using organic polymer foam impregnated with a dross and then dried to be fired, the channel within it has one or more at least partially dense inner wall claddings to determine the flow path of the medium passing through the body. For the inner channel wall cladding, a non-woven is inserted against the surface, of glass or ceramic fibres. The non-woven expands at least to the dia. of the channel, is coated on one side with a dross, and is laid on a section of a holder. The foam body, with the channel, is inserted over the non-woven. The holder section is expanded, to press the coated side of the non-woven against the inner wall of the channel so that the channel surface is at least partially covered and sealed. The pref. non-woven thickness is 0.1-1.0 (0.2-0.6)mm. The dross has an additive of ceramic or organic fibres at a rate of 1.0-10.0 (1-3) wt.%, and the coating on the non-woven is 1-8 mm thick, and pref. 2-4 mm. The ceramic foam body, in sections to give separated flow zones, is covered at the outer sides and the ends by a carrier layer impregnated with a dross, to seal it for firing. Sections to be bonded together and sealed from each other are assembled with an impregnated carrier layer and then further dried. ADVANTAGE - The method gives a foam body where the flow path of the medium passing through it can be altered and extended. (6pp Dwg.No.4/4)
