Abstract: Composite sections of differing cross sectional shapes and sizes can be produced from individual profiles economically by a method in which separate guides are associated with each profile. The guides can be adjusted transversely and vertically. The guides act through guide surfaces which bear upon the top, bottom and both sides of each profile.

Abstract: The penetration of moisture between casing (1) and ignition cable (3) is avoided in cable plugs in that at least one seal ring (9) is provided, which as the ignition cable (3) is pushed in is squeezed into an annular shoulder (10) of the head section (6) and thereby forms a seal.

Abstract: To extend the useful life of the elastic seal (6) which is arranged between a base plate (1) and a cover plate (2) of molds for the production of flat moldings of curable casting resins and through the passages (8) of which the mold cavity is charged with the casting resin melt and vented and to accelerate venting and filling, the passages (8) are in the form of fixed capillary tubes (9) which project partly into the seal (6) and which are each adjoined by a channel (10) opening into the mold cavity (3) and closure needles (13) insertable into the channels are provided.

Abstract: A process for the manufacture of injection molded articles out of material that is capable of being processed in an injection molding process comprising injection fluid material into a hollow space of a mold of a desired form, hardening or reacting the injected material at raised temperatures and subsequently separating the molded article from the mold at the same high tempeature by the aid of inert gas and/or air, pressed between the molded article and the mold, which is regulated by a self readjusting conical valve.

Abstract: This invention relates to a pneumatic tire comprising a tread surface and two separate side parts of an elastomeric synthetic resin and optionally reinforcing elements, wherein the side part not only forms the side wall of the tire but extends from the rim wire to the mid-line of the tire and therefore also forms the foundation for the tread surface on one side, and to a process for the manufacture of such pneumatic tires.

Abstract: The invention is related to a method of assembling a segmented tire mold core from core segments inside a tire mold, a method of splitting up and removing a segmented tire mold core from a tire mold and an apparatus comprising a tool which determines the outer contour of a tire and a segmented tire mold core which determines the internal contour of a tire, as well as the associated charging, conveying and control devices.

Abstract: This invention relates to a process for the manufacture of a tire in segments in a closed mold wherein the internal surface of the mold determines the shape of the external surface of the tire segments, comprising:(a) radially moving from the center of a mold towards the internal surface of the mold a molding tool which determines the shape of the internal surface of the tire segments while leaving a space between said molding tool and said internal surface of said mold, said space conforming to the shape of said tire segments;(b) filling said space between said molding tool and said internal surface with a plastic compound; and when said plastic compound is solidified,(c) moving said mold or said molding tool in the circumferential direction so that the next segment follows immediately upon the segment already produced.
