FIBER REINFORCED POLYMER COMPOSITE STRUCTURES AND ELECTROMAGNETIC INDUCTION PROCESS FOR MAKING SAME
The present invention relates to resin compositions, fiber reinforced polymeric structures and electromagnetic induction processes for making same. Such magnetic induction processes are pulsed processes that can be optionally coupled with cooling steps between pulses. The aforementioned fiber reinforced polymeric structures can take forms that include, but are not limited to, pipes; pressure vessels, including rocket motor cases and fire extinguishers; golf club shafts; tennis and badminton racquets; skis; snowboards; hockey sticks; fishing rods; bicycle frames; boat masts; oars; paddles; baseball bats; and softball bats. In addition, such fiber reinforced polymeric structures can be supplemented with other materials, such as a rocket propellant, to form articles, for example, a rocket motor.
Method and systems for applying stretch films/plastic films at a controlled temperature
A system for controlling the temperature of a film before and/or during application, the system including: a heat source for heating a film; and stretch rollers; wherein the heat source heats the film from an ambient temperature to a temperature from about 2° C. to about 40° C. above the ambient temperature, wherein the film is heated prior to or simultaneous to being stretched by the stretch rollers, and wherein the ambient temperature is below 15° C. The preheating system may be used to enhance binding and sealing properties of stretch films used for wrapping palletized products in a reduced temperature environment. Other embodiments of the preheating film system, and methods for its use, are described herein.
Method and systems for applying stretch films/plastic films at a controlled temperature and/or transfer of electrostatic charge
A system for controlling the temperature of a film before and/or during application, the system including: a heat source for heating a film; and stretch rollers; wherein the heat source heats the film from an ambient temperature to a temperature from about 2° C. to about 40° C. above the ambient temperature, wherein the film is heated prior to or simultaneous to being stretched by the stretch rollers, and wherein the ambient temperature is below 15° C. A system for improving the application of film by transfer of electrostatic charge is also described.

METHOD AND APPARATUS FOR PRODUCING THREE-DIMENSIONAL DECORATION PIECE MADE OF THERMOPLASTIC SYNTHETIC RESIN
A method and an apparatus for producing a three-dimensional decoration piece that does not damage the tacky bonding or adhesion strength of the lower layer material of the decoration piece. The method includes putting an upper layer material on a first table operating as cathode; lowering an upper mold operating as anode onto the first table, emitting a high frequency wave for dielectric heating; stopping the high frequency dielectric heating; moving a second table carrying a lower layer material having a tacky bonding property to below the upper mold; and lowering said upper mold onto the second table. In the apparatus, the second table or the lower mold is provided on the top surface thereof with recessed sections that are transversally and inwardly separated from a position where an edge of the first machining means contacts, by 0.2 mm to 1 mm; and a cushion member being arranged in the respective recessed sections.
