  • Patent number: 5324565
    Abstract: Accumulated dimensional variations in fuel cells and electrolysis cell assemblies can reduce the efficiency of the assembly and provide leakage paths for fuel and oxidant. An elastomeric compression pad comprised of an oil adsorbent sheet surrounding an elastomeric material with expansion pathways and electrical pathways, that utilize a conductive powder and elastomeric binder compensates for component dimensional variations, improves inter-cell conductivity, and allows high pressure operation up to about 3,000 psig.

  • Patent number: 5320895
    Abstract: An absorbent pad for use with meat and poultry products in retail sale packages has a laminated tissue absorbent mat sandwiched and sealed between upper and lower plastic sheets. The pad is perforated by penetration of perforating pins entirely through the pad to develop a series of holes for the passage of liquid from the meat package into the absorbent mat inside the pad. A myriad of outwardly projecting tufts of tissue material are developed along the underside of the pad by the perforating pins. These tufts develop a wicking effect which enhances the capillary action of the tissue layers inside the pad. Methods of fabrication of the individual pads and continuous linear absorbent sheet material are also disclosed.

  • Patent number: 5320893
    Abstract: A method of protecting a metal layer of a solar reflecting coating on a heat-shrinkable substrate, which are components of a prelaminate for a laminated window, from atmospheric corrosion. The prelaminate is cut partially through its thickness adjacent the edge and when the region of the cut is later exposed to elevated temperature, preferably during the laminating process forming the window, the substrate shrinks to create a channel into which flows plasticized polyvinyl butyral (PVB) to block the edge wall of the coating inward of the channel from the surrounding atmosphere.

  • Patent number: 5316821
    Abstract: A partition plate for multiple-stage adsorption separator includes a planar body member having opposing external surfaces and a peripheral edge with conduits providing fluid communication between the opposing surfaces and different points on the peripheral edge. Each of the opposing surfaces is provided with a peripheral rim and covered with a perforated plate whereby an open chamber is defined between the body member and a perforated plate at each of the external faces.
