An adhesive sheet for reinforcing thin rigid plates is disclosed, which comprises a thermosetting resin composition layer and a reinforcing substrate laminated or embedded therewith, the reinforcing substrate having undergone sizing treatment with a heat-resistant resin to have stiffness, and the thermosetting resin composition layer having tackiness at room temperature and comprising a thermosetting resin and a hardener.
摘要:
A glove having patterned polyurethane coating adhered to outer surface. The coating is about 1/32 inch high and about 1/16 inch wide to give the glove slip-resistant and gripping properties. The coating is formed from (a) a pre-mixed thixotropic component, a non-thixotropic component in a 2.5 to 1 ratio, and an accelerator, and (b) a cross-linking agent. The method of manufacturing the glove involves applying a mixture of (a) and (b) as a strip to the glove, allowing the strip of coating to wet the fibers and then curing at a low temperature for a relatively short period of time.
摘要:
A helmet has a generally dome shaped helmet body with inner and outer sides and a lower edge extending generally in the shape of a loop; an elongated reinforcement member is embedded in the helmet to extend proximate the looping lower edge portion; that member may have band shape; and additional such band shaped reinforcement members may extend within the dome shape of the helmet, such as laterally spaced rib or ridge portions.

A shape retention hose construction and method of making the same are provided, the hose construction comprising a length of flexible tubular hose formed mainly of polymeric material and having opposite end portions and an intermediate body portion that defines internal and external peripheral surfaces of the hose, and a shape retention unit carried by the hose and being adapted to generally retain the shape of the hose construction when the hose and its carried shape retention structure are jointly bent into a particular shape, the shape retention unit comprising a deformable elongated member having opposed ends, the hose having a radially outwardly disposed and longitudinally extending projection on the external peripheral surface thereof, the elongated member being longitudinally disposed in the projection, the projection having opposed ends that respectively are disposed inboard of the opposite end portions of the hose, the opposed ends of the elongated member also being respectively disposed inboard of the opposite end portions of the hose, the end portions of the hose respectively having external peripheral surfaces that have substantially circular cross-sectional configurations through-out the axial lengths thereof.
摘要:
The present invention provides a reinforced plastic laminate structure comprising an elongated reinforcing material that is encapsulated by an extruded plastic material that forms a continuous structure around the reinforcing material. The present invention contemplates methods of extruding a tube of plastic material while simultaneously introducing a reinforcing material within the interior of the tube. Thereafter, the tube is flattened so that the interior wall of the tube comes in contact with the reinforcing material to encapsulate the reinforcing material in a continuous structure. The reinforced plastic laminate sheet is made from an apparatus an extruding machine for extruding plastic with an annular die and opening for the extruding tubing. Attached to the extruding machine is a mandrel which feeds a reinforcing material into the center of the annular opening. Pressure rollers flatten the tubing after it exits from the annular die. The reinforcing plastic material may be formed into a variety of useful products where increased strength is required. The ease of manufacture provides a cost advantage over conventional construction materials.
摘要:
Resin is mixed with graphite particles to form a blendable, processable premold coating. When the premold coating is incorporated onto the surface of a premold coated molded plastic product produced by the premold process, said coating is rendered electrostatically conductive.
摘要:
The present invention provides a method for reinforcing a substrate, which includes the step of coating at least a portion of the surface of the substrate with a layer of material that is curable by a high-energy-radiation. The coating material is cured with a suitable source of the high-energy-radiation to form a reinforcement layer affixed to the substrate. The reinforced substrate is particularly useful in the attachment zone of a refastenable, pressure-sensitive tape closure systems.
摘要:
A die for operating on workpieces has first and second workpiece supporting surfaces opposed edges of which are in stepped relation to each other for supporting the workpieces in overlapping relation. A shoulder joins the edges of the surfaces for limiting the overlapping relation of the workpieces and a ridge in the one of the surfaces supporting an overlapped workpiece runs substantially parallel to the shoulder to urge workpiece material toward the shoulder.
摘要:
A precast decorative panel is formed by filling a flexible mold to a selected level with an unset thermosetting resin and aggregates. After a nonrigid member, which is smaller than the receptacle, is placed on top of the mixture of resin and aggregates, a filler mold, which is smaller than the receptacle and substantially the same configuration so as to form a substantially uniform space therebetween, is disposed within the receptacle. This uniform space is filled with aggregates and an unset thermosetting resin. After the unset resin is partially cured to a soft gel, the filler mold is removed. Then, the partially cured resin is separated from the mold. This produces a panel having a textured top surface and a bottom surface with a drop edge extending therefrom along the entire periphery of the body of the panel.
