Abstract: Reinforced glass produced by overlaying a coating of thin material on a surface of a plate of glass which is optionally silvered, coating a mixture of silicone and epoxy resin on another surface of the glass, and drying at ambient temperature. A layer of highly-exothermic unsaturated polyester resin is then coated on the surface of the glass and dried. The glass is placed into a mould with the uncoated surface facing downwards. A suitable amount of lowly-exothermic unsaturated polyester resin is poured into the mould. A layer of highly-exothermic unsaturated polyester resin is coated on a surface of a plate of reinforcing material and dried. Before the lowly-exothermic unsaturated polyester resin is completely dried, the reinforcing material is overlaid on the glass with the coated surface of the reinforcing material facing downwards. The resultant assembly is then pressed and dried.

Abstract: An apparatus and method is provided for forming a textured pattern on a heated substrate. An extruder forms the heated substrate. A textured pattern is applied to a transfer sheet by rotary screening. Thereafter, contact is made between the textured pattern and the substrate for adhering the textured pattern to the substrate. Since the textured pattern has a greater affinity for the substrate than for the transfer sheet, the transfer sheet can be removed from the textured pattern adhered to the substrate. In a preferred application, the textured pattern formed on the substrate can be used as a vertical, horizontal or venetian blind.

Abstract: A device for selectively connecting and disconnecting plastic tubes includes a welder. A carriage is located in the welder for conveying a heated wafer through the welder. A pair of arms is mounted in the welder with each arm having a tube holding pocket which extends across its respective arm. The arms are movably mounted to generally align the pockets with a gap therebetween. Each of the arms has a clamp for selectively clamping a tube in its pocket. A wafer removal station is in the welder downstream from the arms. The carriage is driven to the wafer removal station so that the wafer first passes through the gap to contact the tubes and then the wafer passes into the removal station so that it may be removed from the carriage and the carriage may be returned to its starting location. The welder includes a computer for controlling the operation and synchronizing the timing of the carriage and the arms to automate the welder.

Abstract: A method for preparing a microporous ink-impregnated marking structure according to the invention involves use of a window-like frame instead of a conventional chase. The frame is placed on the upper face of the matrix board or mold so that the premix, containing ink, plasticizer and resin, is retained therein. The premix fills the cavities and excess premix forms a continuous layer over the cavities in the mold, with the edges of the layer retained by the frame. A layer of an ink-absorbent backing material is placed on the layer of premix, and the backing is covered with a plate. The assembly is heated with pressure to form a microporous, marking fluid impregnated structure having a relief pattern corresponding to the cavities, and then cooled. The marking structure can then be used to make self-inking hand stamps.

Abstract: The present invention relates to the integral extrusion of closure profiles and a film through a film die. The present invention provides an apparatus for integrally extruding a film and closure profiles from a single stream of molten material and, consequently, eliminating any joining problems between the film and the closure profiles. The present invention utilizes a removable die lip with removable profile wedges that mount in the die lip and extrude the closure profiles and a film together from a single stream of molten material. In this manner, the closure profiles and the film are integrally formed, and if a new closure profile design is desired, the present invention permits the quick and economical replacement of a removable profile wedge with another.

The seat stays combined with the seat support means which are connected to parts of the top tube and seat tube, and the chain stays combined with the pedal support means which are connected to parts of the down tube and seat tube, are formed respectively. The seat stays connect to the chain stays by inserting a pair of rear wheel dropouts therebetween, to form substantially a pair of rear triangles of the bicycle frame. The seat tube and the steering support means connected to the top tube and down tube are laid up respectively. The cured rear triangles connect to uncured seat tube and steering support means associated with top tube and down tube, wherein the top tube, down tube, and seat tube form a front triangle. The front triangle is cured such that manufacturing of the whole bicycle frame is completed.

Abstract: A flame resistant to nonflammable composite panel is produced from a nonextrudable core mixture with a pourable, nonflammable filling material and a binder, and on both sides cover strips flexibly bonded to the core. For a continuous production of the composite panel in one operation, the core mixture is poured onto an inrunning lower cover strip, in contact with a lower adhesive film facing the core mixture, and a pile is formed there, extending over the entire width of the adhesive film, both continuously and uniformly drawn through a V gap and compacted there for the first time and calibrated to thickness, an upper adhesive film, upwardly limiting the precompacted core mixture, is fed in and brought into contact with a continuously fed cover strip and the sandwich is pressed with further compaction, heated, cooled and cut to the final length of the composite panel.

Abstract: A process for forming a shaped prelaminate of glass and plastic by a) drawing an assembly of plastic layers against a hot, contoured, e.g. of compound curvature, mold surface to provide a shaped plastic preform at elevated temperature; b) transferring the shaped preform without cooling to an adjacent unheated glass layer of substantially matching surface contour to heat bond the shaped plastic preform to the glass layer; and then c) removing heat from the shaped plastic preform via conductive heat transfer to the glass layer to form the shaped prelaminate of glass and plastic layers. A bilayer glazing panel is formed in a conventional unmodified autoclave bonding system by exposing the prelaminate to elevated temperature and pressure to firmly bond the plastic to the glass.

Molds are prepared by loading a press with outer layers of said molding core and an inner layer comprising a combination of an epoxy non-woven glass mat and a woven glass cloth prepreg. Finally, the press is actuated at low pressure while applying heat to pregel said epoxy and the increasing the pressure to form said molds. As another aspect of the present invention, a three-dimensional relief is imprinted from a textured substrate to a thermoplastic composite.

Abstract: A resilient pad of intertwined nylon fibers of minute cross-sectional diameter having minute interstices throughout. The pad serves as a breather for the curing of a part of composite resinous material for which purpose it is placed over the part, which part is, in turn, fitted onto a shaped tool. To effectuate curing of the part, the part and breather pad are covered by a vacuum bag which is, in turn, sealed around its edges to the shaped tool and provided with a vacuum outlet. The whole assembly is then placed in an autoclave, wherein it is subjected to heat and pressure while vacuum is applied to the vacuum bag to evacuate air and volatile effluents from the part through the breather pad while the part is being cured under the influence of heat and pressure.

Abstract: A sterile containment welding device for plastic tubes comprises a pair of side by side spaced tube holders. Each of the tube holders includes a clamp base and a clamp lid. A pocket is provided in each clamp base extending completely across the clamp base so that a plastic tube could be inserted into the pocket and clamped in the holder when its clamp lid is moved to a closed position. Pockets of the side by side tube holders are alignable with each other to permit a plastic tube in one of the holders to be welded to the plastic tube in the other of the holders. A tube locating member is movably mounted at the end of each pocket in the space between the holders. The tube locating member has a wall disposed in the space beyond the pocket for positioning its plastic tube in the proper position for the later welding step when its tube is moved into contact with the walls.
