  • Patent number: RE32671
    Abstract: A flue control device for slowing the rate at which heated exhaust gases rise through an exhaust stack comprises a cylindrical housing enclosed by end caps, with an offset inlet and outlet being positioned in opposite end caps. The interior of the housing defines a baffle chamber, and a baffle mechanism is positioned in the baffle chamber between the inlet and outlet. The baffle mechanism comprises two overlapping plates, each plate having a prominent flange extending in an upstream direction relative to the flow of gases through the baffle chamber. The flanges interrupt and slow the swirling circular flow of gases as they pass through the baffle chamber. The baffle and housing are of a size such that the cross-sectional area of the restricted portion of the housing adjacent the baffle is at least as large as the cross-sectional area of the exhaust stack.

  • Patent number: RE32673
    Abstract: A process and apparatus is provided for the production of calcium silicate-containing stone blanks which are useful in constructing building walls. A crude mixture, of a granulated silicate-containing material, lime, water, a cement and a foaming agent, is subjected to no more than a minimum application of external pressure and is subsequently hardened in an autoclave. The cement produces the necessary strength for the blank, so that the latter becomes transportable while the final strength is achieved by reaction of the silicate-containing material during the autoclave treatment. In order to arrive at acceptable molding times and in order to achieve a simplified process with slight fragment bulk density and optimal head damping characteristics, the crude mixture is rendered pourable, is filled into molds in a quantity corresponding to the fragment volume of the stone blank, and the crude mixture in the mold is heated essentially uniformly to a temperature between 45.degree. C. and 90.degree. C.

  • Patent number: 4745636
    Abstract: Disposable apparel shorts fabricated from a single blank of non-woven textile sheeting, the blank having opposing isosceles triangular indentations therein whose vertices lie at the opposite ends of a transverse center line. When the blank is folded on this line to form identical superposed sections, these constitute the front and rear sections of the shorts in which the upper margins of the sections define the waist, and the folded-over triangular indentations define the leg openings. The side margins of the front section are folded in and the corresponding side margins of the rear section are folded over the folded-in margins to define side vents in the leg openings to provide additional space, should it be required by the wearer. An elastic band is bonded in its stretched state to the inner surface of the upper margins of the sections to create a shirred circular waist which is expandable to conform to the waist of the wearer.

  • Patent number: 4745655
    Abstract: An air-powered vacuum-producing apparatus or vacuum tool is disclosed which may be utilized in combination with a discharge collection assembly to pick up and collect debris, dust and liquids. The apparatus may be powered by any suitable, relatively high pressure gaseous medium such as compressed air. The apparatus includes a body having an elongated central chamber and a high pressure inlet, a suction inlet and a discharge outlet in communication with the chamber. The high pressure inlet is located downstream of the suction inlet and injects pressurized gaseous fluid into the chamber so as to more efficiently create a reduced pressure area or vacuum adjacent to the suction inlet. The body may be provided with first and second interconnected body portions respectively having first and second interconnected chamber portions.
