Abstract: A brush roller assembly for a vacuum cleaner sweeper which includes a rotatable spindle having a longitudinal axis, a first end, a second end and a central portion, a first bladed disk positioned on the first end of the rotatable spindle, the first bladed disk including a central portion which is positioned substantially perpendicular to the longitudinal axis of the rotatable spindle when the first bladed disk is positioned on the first end of the rotatable spindle and at least one fan blade projection outwardly extending from the periphery of the central portion of the first bladed disk, the at least one fan blade projection being oriented to facilitate the movement of outside air from the first end of the rotatable spindle toward the central portion of the rotatable spindle, a first end cap attached to the first end of the rotatable spindle, a second bladed disk positioned on the second end of the rotatable spindle, the second bladed disk including a central portion which is positioned substantially perpend

Abstract: An improved cartridge loader for releasable securement of cartridges to be simultaneously loaded into the cylinder of a revolver. A pintle rotates between a cartridge engaging position and a cartridge releasing position and is held in positive engagement with the loader body by the action of a spring-loaded pin assembly along a pin-engaging surface. The pin-engaging surface may be formed in the pintle and the pin assembly is substantially located within the loader body.

Abstract: A semi-pneumatic tire assembly including a tire casing 22 and a lining 26 is provided. The lining 26 includes a contoured inward surface 30 defining an inflation chamber 18 about an associated wheel rim. The lining 26 minimizes the risk of puncture damage from an object penetrating the tire casing 22 while allowing pneumatic cushioning of the ride and cooler running temperatures as compared to solid-fill tires. Additionally, the semi-pneumatic tire will carry the same load or more than the same tire filled with perform and/or solid urethane foam wingfil. The tire assembly is formed by injecting a curable, lining-forming material 96 into a cavity 57 defined between the tire casing 22 and a molding member 50. The molding member 50 includes a contoured outer surface 54 which molds the inward surface of the lining 26. The molding member 50 may be an inflatable airbag 100 retained in the tire assembly during service.

Abstract: Crossbow bowstring drawing mechanisms which are integrated into or secured in the crossbow handle and which provide a straight and balanced draw to the crossbow bowstring to cock the crossbow bowstring in position in the crossbow trigger mechanism ready for firing. The cocking system can be manually operated or motorized, and can be manufactured as part of a crossbow or retrofit into a crossbow. An internal or external source of rotational power, such as hand crank, power screwdriver or an electrical motor, is preferably utilized in conjunction with a claw member including a bowstring engaging portion to translate rotation of the input source to longitudinal movement of the claw member to draw or release the crossbow bowstring resulting with minimal effort being expended by the user. The claw member may include adjustable cams used to center the claw member with respect to the crossbow barrel.

Abstract: A mower deck comprises an auxiliary source of pressurized air in order to avoid clipping buildup under the mowing deck, most particularly at the trailing edge of the discharge chute. The auxiliary source of air comes through a cloverleaf shaped hole in the mower deck. The spindle is mounted to the mower deck through this hole, as in conventional mowers. However, unlike conventional mowers, because the hole in the mower deck has a cloverleaf configuration air can flow through the corner portions of the cloverleaf configured hole and act as an auxiliary source of air even though the spindle is mounted to the mower deck through the hole.

Abstract: A method of coating ferrous and nonferrous metal substrates that provides cathodic protection from corrosion by coating with inherently conductive polymers and sacrificial anodic metal particles. This method of coating is characterized by its conductivity and cathodic corrosion resistant qualities.

Abstract: An apparatus for dispensing cream products such as deodorants and the like from a concealed product tube. A rotatable propeller drives a threaded spindle having a piston elevator mounted thereon. As the spindle rotates, the piston elevator rides upward, pushing the product toward an application surface.

Abstract: A candle with an excellent attractive effect of color change with the use of positive and negative types of thermochromic dyes which develop a highly dense color on heating to the melting point of wax. These are composed of a plurality of (A) an electron donating chromogenic organic compound, (B) an electron accepting aromatic organic compound, (C) a medium selected from aliphatic alcohols or paraffinic waxes, (D) one or more of oil-based fragrances containing aromatic aldehydes, ketones, or esters, and (E) soluble halides or nitrates of transition metals. By controlling the relative proportions and the physical proximity of a plurality of ingredients from (A) through (E) in a candle or candle wax or other waxes, a color develops from a colorless state giving a positive thermochromic effect, the initial color is erased giving a negative thermochromic effect on heating or when the candle burns.
