Abstract: A fire damper is provided with a central flange for mounting within a wall. The flange having a plurality of holes allowing any plaster material in the wall construction to pass through the holes and retain the damper. A miter cut is provided at the corners of the damper and the flange to allow for expansion during a fire. The damper is positioned within an opening in the wall with the flange positioned within the opening of the wall. The wall is built up by applying mortar against the damper and extending flange. With the mortar being forced through the holes in the flange to hold the damper in place.

Abstract: A sanitary napkin shaped to fit the contours of a thong garment from the front of the wearer to the crotch of the wearer. The napkin is generally "V" shaped, so that the vertex of the "V" can be positioned below the vagina of the wearer. The napkin is generally V-shaped with a bulb-shaped top end and an elongated lower portion, so that the vertex of the "v" can be positioned below the vagina of the wearer.

Abstract: The dry charge machine and method disclosed carefully monitor the temperature above and below the plates as well as the water temperature exiting the machine and introduce cooling water at a flow rate and temperature so as to maximize thermal efficiency in drying and minimize the energy necessary to raise the temperature of the drying gas. The machinery is arranged and controlled so that water droplets are not introduced into the air. Oxygen leakage into the machine in minimized and the oxygen content of the air is monitored.

Abstract: A damper is provided with a plurality of lugs on one side opposite to its face which lugs can be rotated to interfere with removing the damper from the wall in which it is mounted. The lugs can be rotated from the outside and fastened in position without having to go around the wall.

Abstract: A wind energy conversion system employs a wind turbine means mounted on a frame, said wind turbine having a venturi configured shroud with a core and a plurality of blades fixedly mounted between the core and the throat of the venturi. The blades have an air foil design consisting essentially of an inverted pan-shaped, cross-sectional configuration to create high torque at low air speed.

Abstract: A fishing reel having a drag mechanism with juxtaposed surfaces relieved in those areas which are opposite the highest sections of the working cam surfaces to thereby increase the drag.

Abstract: A mechanism is provided to engage a resettable link in a curtain-type fire damper and release and reset that link so that the blades of the damper can unfold. The mechanism is actuated remotely and mechanically without the need for an access door.

Abstract: A message display boot is provided for a fuel dispensing nozzle. The display boot comprises a flexible plastic boot in close conforming fit over at least the front valve housing of the nozzle. At the top of the boot is a message platform upon which a message placard can be rested. A skirted flexible cover conforming to the contour of the platform has a pattern of scalloped expansion folds, such that the cover is held on the platform by the close conforming fit of the skirt along and under the sides of the platform but can be easily pried off the platform to change the placard. The cover can be optically clear to hold a message placard on the platoform, or it may have a message imprinted on its top surface. A bellows portion at the bottom of the boot provides a conforming fit over nozzles of various height. In a preferred embodiment, the boot, platform and bumper are integrally molded of plastisol vinyl.

Abstract: A battery for operation in hot dry climates is provided with unique plate grids and a floated insulating layer over the electrolyte.

Abstract: An apparatus and method are disclosed for continuously accumulating, screening, stacking and packaging disks such as hamburger patties automatically and without the use of personnel in contact with the patties. This includes weighing the patties by optical comparison means so that the finished package is within the tolerances permitted for weight of goods.

Abstract: A bladder-less counterpressure garment primarily used in the treatment of a victim suffering from hypovolemic shock. The garment is made of a resilient material, like elastic, with a means for stretching the material to or near its stretch limit. This stretching supplies the requisite counterpressure to increase blood circulation to the vital organs.

Abstract: A carburetion and combustion system is provided in which the carburetor discharges a combustible fuel/air mixture in a rotating swirl from a plurality of nozzles at one end of a cylindrical combustion chamber, and discharges a rotating helical swirl of high-velocity compressor air concentrically surrounding the combustion mixture from a second set of nozzles. The high-velocity air swirl confines the flame propagation away from the combustible chamber walls and provides the walls with an insulating layer against the combustion heat.

Abstract: A multicell storage battery may be assembled to fit various floor space and height requirements by using standardized multicell modules having keyed connector means such that the modules can be connected only in selected orientations which facilitate the electrical connection of terminals. These standardized modules eliminate the need for standard and reverse polarity modules which existed in the prior art, and simplify battery assembly on site while allowing greater flexibility to adjust to space limitations. The keyed connectors comprise mating structures on the sides of the rectangular frame of the modules, which in combination with the modules being configured to stand vertically, create cooling ducts for the cells. An easily installed safety shield encloses the terminals of the cells and provides a front cooling duct.

Abstract: An electrical generating system in which exhaust steam from the turbine is recycled through the turbine to reduce feedwater requirements and condenser complexity. The turbine is an axial flow dual shaft compressor/turbine unit in which a coaxial shaft couples the turbine section to the compressor section. A portion of the energy extracted from the steam is used to power the generator and the remainer is used to power the compressor. The turbine exhaust steam is directed through compressor section and the compressed steam is then mixed with turbine inlet steam by a steam jet ejector. The compressor may be powered from either one or both shafts from the turbine.

Abstract: A device and method for quickly aligning a machine tool spindle to the work surface of the machine tool. The device comprises a shank designed to be attached to the machine tool spindle, transducers used to sense the work surface, and indicators used by the operator to calibrate the position. The device can be used to determine and set the proper angle of the machine tool spindle in any two dimensions.

Abstract: We have discovered that the introduction of small particulate matter into the area between the electrolyte and the inner surface of the battery cover can dramatically reduce water loss, if the material possess the following properties:The material should have a closed cell, which is not a solid material in a sense that it is a plurality of hollow structures linked together.
