The material provided in step (b) is preferably selected from 1. a mixture composed of or comprising (a) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which are substituted by one or more SH groups, and (b) a purely organic compound having two or more isolated C=C bonds, 2. a mixture composed of or comprising (a) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which have one or more isolated C=C double bonds, and (b) a purely organic compound substituted by two or more SH groups, und 3. a mixture composed of or comprising (a) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which are substituted by one or more SH groups, and (b) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which have one or more isolated C=C bonds.
Abstract:
A three-dimensional object fabrication apparatus is disclosed. A housing encloses a work area having at least two distinct zones including a fabrication zone and an assembly zone. Digital data defining geometry for a three-dimensional object to be fabricated is passed via an interface to a processor within the housing. A fabrication mechanism in the fabrication zone to fabricates sub-elements where each sub-element corresponds to a portion of the object substantially consistent with the digital data. An assembly mechanism in the assembly zone joins the sub-elements in relative alignment to form the object defined by the geometry.

Abstract:
The invention relates to a method for producing a hollow composite structure consisting of a polymeric material which is reinforced with fibres. According to said method, said fibres (F) are arranged first in order to form a reinforcement element (1), before this element is applied around a mould core (13) and the arrangement is integrated by moulding.
Abstract:
In combination, a container and a linerless cap and a method of forming the cap (10). The cap (10) includes plastic and has a sealing surface (42) which is softer than contiguous plastic portions as a result of its method of forming which includes stretching. In the method the cap (10) is molded from plastic and includes a top wall (12), an outer depending skirt (14) and an internal depending substantially annular wall (18) having an upper end (20) integral with and depending from the top wall and a lower free end (22). Thereafter the free end is engaged by a forming tool (26) to progressively turn the free end (22) away from the internal wall (18) to create a stretched intermediate portion (24) for sealing which is softer than its contiguous portions.
