Abstract: An electrical insulating and heating element support assembly for a high temperature vacuum furnace having a threaded support rod for connecting a heating element to the insulated hot-zone support ring in an electrically non-connected position includes insulator sleeves and washers surrounding the rod in contact with a series of refractory metal washers which may include graphite and/or molybdenum as shielding liners used to protect electrical insulators from having electrical short path means due to deposition of conductive materials onto the non-conducting insulators, and the use of threaded nuts and bushings to anchor the rod and shielding arrangement within the furnace hot zone. The non-conducting insulators and washers are made from materials with high thermal and electrical resistance, such as preferably alumina or mullite, and radially surround the support rod and the heating element.

Abstract: A unique combination of a hydrophilic polyol (A) and a hydrophobic polyol (B) having a terminal ethylene oxide cap are used in a resin composition and a polyurethane system, and are used to form a polyurethane article, such as a polyurethane foam. The hydrophilic polyol (A) is ethylene oxide (EO) rich and the hydrophobic polyol (B) is propylene oxide (PO) rich. The hydrophilic polyol (A) and the hydrophobic polyol (B) are present in the resin composition and the polyurethane system in a weight ratio (A:B) of from 1.5:1 to 20:1. The polyurethane article exhibits excellent comfort for use in vehicle applications, such as automotive and motorcycle seating, due to reduced resonance frequency and reduced peak vibration transmissivity relative to previous polyurethane articles.

Abstract: A device for separating and removing kraeusen from fermenting beer. The device includes a pan having a circular bottom wall with a peripheral side wall extending upwardly therefrom. In the center of the bottom wall is a cone-shaped recess that serves as a well for the collection of particulate matter falling from suspension in kraeusen. Extending upwardly from the bottom of the recess to a height approaching that of the side wall is a tubular passageway for the upward passage of kraeusen into the pan. The recess may be covered with a screen or perforated plate upon which particulate matter can collect. An aperture is provided in the tubular passageway at the top of the recess to permit any beer carried by kraeusen into the pan to drain from the pan.

Abstract: A molded flexible polyurethane composition having improved polycarbonate compatibility comprising an organic polyisocyanate, a polyol and reactive tertiary amine catalyst. This catalyst contains at least one active hydrogen and/or hydroxyl group in its structure. Another embodiment of this invention relates to a molded flexible polyurethane composition having improved polycarbonate compatibility comprising an organic polyisocyanate, a polyol, a non-reactive tertiary amine catalyst and, an amine scavenger composition which may or may not also contain reactive tertiary amine catalysts. Also disclosed are processes for making said molded flexible polyurethane compositions having improved polycarbonate compatibility.
