Abstract: Method and structure for insulating a building wall, ceiling, or like member supported by studs or rafters along various areas thereof, comprising the use ofan inflatable envelope of gas impervious material wherein the inflatable envelope includes at least two main wall portions;a first heat transfer barrier member substantially fully covering and secured to one of the main wall portions externally of the inflatable envelope;a second heat transfer barrier member substantially fully covering and secured to the other of the main wall portions externally of the inflatable envelope;a member separating the two main wall portions situated within the interior of the inflatable envelope and disposed between two main wall portions; anda valve for facilitating entry of an inflating medium into the inflatable envelope and retaining an inflating medium within the inflatable envelope; the method including installing the structure, securing it in place, and inflating the envelope.

Abstract: Apparatus through which electrical cables of an underground distribution system may pass from a generally horizontal plane to a generally vertical plane so as to be directed upwardly for connection with terminals of an above ground transformer comprising:A hollow generally horizontal portion;A hollow generally vertical portion integral with the hollow generally horizontal portion, the hollow generally horizontal portion having at least one end with a first opening, the hollow generally vertical portion having an upper end with a second opening, the hollow generally horizontal and vertical portions intersecting each other at a lower end of the generally vertical portion to provide communication between the first and second openings through the generally horizontal and vertical portions; andAn arcuate guide member extending within the generally horizontal portion and including a lower section merging into a lower surface or floor of the generally horizontal portion, the arcuate guide member extending from the l

Abstract: A reusable gasket for use in and in combination with a molding apparatus for casting articles of acrylic monomer plastic or the like. The gasket comprises a mold and casting release surface for contact with a cast plastic article and the two mold surfaces and includes a core of elastomeric material completely, but loosely encased in a tube impervious to passage therethrough by the material of the core and the material of the plastic article to be cast. The impervious tube may be of polytetrafluoroethylene, polyamide, polyethylene, or like material. The mold and casting release surface is preferably silver. A plurality of gasket members are placed in end-to-end relationship between a pair of plate members in a molding apparatus to define a casting cavity. A plug in the form of a wedge may be used to close a gap between adjacent ends of two gasket members through which casting material may be flowed into the cavity prior to closing the gap.

Abstract: This invention is directed to an aerator device and method for generating fine bubbles from a liquid and gas mixture. In particular this invention is directed to aeration of liquid to generate fine bubbles for industrial as well as for domestic use.

Abstract: Method for developing gas pressure to drive an engine consisting of establishing equal cooperating gas portions in separate containers a close circuit; developing pressure change in one of the portions by changing temperature; establishing communication between containers, allowing pressure equalization in containers by gas flow from container given greater pressure to the other; cutting communication between containers after pressure equalization; redeveloping gas pressure change in one container, obtaining relative pressure increase in the container to which gas flowed by changing the temperature in one container; and driving an engine by establishing gas flow communication between the containers through the engine.

Abstract: This invention relates to the sealed faucet valve assembly which is particularly designed to repair corroded or damaged valve stem mechanisms without replacement of the entire faucet. Included is a novel faucet washer assembly which provides a sealed chamber to protect the securing screw from contact with corrosive liquids.
