Abstract: This invention provides single-step pultrusion processes for producing fiber reinforced polymer (FRP) articles that may have variable cross sections and/or non-linear shapes. This unique capability results from the use of two sets of dies to form the article. The first is a set of moving dies connected together to form mating continuous loops of moving die links to: a) draw the FRP material into the apparatus; b) shape the cross section of the FRP material; c) cut the FRP material to the appropriate length; and d) hold the uncut FRP material in position for the next production cycle. The second set of dies forms a guide path mounted on opposing conveyers. The guide path includes heated die segments to define a curing section that may be non-linear. Cycling the moving die links through the curing section and/or cycling the conveyers provides a straightforward method for automated production of finished pultruded articles with unique shapes.

Abstract: A connector (20) is placed in a first die (50) so that an end of a wall (41) of the connector (20) closely contacts a recess (55) of the first die (50) to define a cutoff (58).

The outer surface (46) of the wall (41) is inclined moderately upward. Molten resin is directed into the filling space (60C) and presses the inclined outer surface (46) of the wall (41) so that an inner surface (47) of the bottom wall (41) is pressed against the recess (55) of the first die (50) and strongly held in close contact by a component of this pressing force. Thus, molten resin cannot intrude through the cutoff (58).

Abstract: High pressure synthesis of various crystals such as diamond, cBN and the like can be carried out using reaction assemblies suitable for use in methods such as temperature gradient methods. The reaction assembly can be oriented substantially perpendicular to gravity during application of high pressure. Orienting the reaction assembly in this manner can avoid detrimental effects of gravity on the molten catalyst, e.g., convection, hence increasing available volumes for growing high quality crystals. Multiple reaction assemblies can be oriented in series or parallel, each reaction assembly having one or more growth cells suitable for growth of high quality crystals. Additionally, various high pressure apparatuses can be used. A split die design allows for particularly effective results and control of temperature and growth conditions for individual crystals.
