  • Process For Reducing Gate Blush and Mold Design For Same
    Publication number: 20240075664
    Abstract: A system and process for injection molding polymer articles is described. The system and process are designed to reduce gate blush. In one embodiment, an injection molding device injects a molten polymer composition into a mold cavity adjacent to an interior curved surface on the mold. The flow of the polymer material is parallel to a line that is tangent to the curved surface.

  • Insulation boards and methods for their manufacture
    Patent number: 7838568
    Abstract: A method of manufacturing a polyisocyanurate foam insulation board, the method comprising contacting a stream of reactants that comprise an isocyanate-reactive compound with a stream of reactants that include an isocyanate compound to form a reaction product, where the step of contacting takes place in the presence of a blowing agent and a low-boiling inert gas, and where the amount of low-boiling inert gas present at the time of the contacting is sufficient to result in frothing of the reaction product.

  • PC radio card capable of operating at a nonstandard power output level by limiting the current being drawn from a power amplifier
    Patent number: 6785830
    Abstract: A hand-held, PCMCIA cellular radio modem card is described which uses a non-standard power output level. The non-standard power output is defined as the maximum RF power attainable such that the current drawn by the power amplifier does not exceed 400 mA. This definition permits the use of the wireless modem inside hand-held computing devices without the use of an additional battery pack extension.
