Abstract: The invention is an adjustable bracket for supporting items on the railings of house decks. The bracket is formed of only two parts without any fasteners. The parts interlock, but can be adjusted to form a clamp around the typical rectangular cross section rail. One part is a support unit which is a simple strap with two bends in it to form two offset sections, and the second part is a clamp unit which is a hook shaped strap with a long leg and a short leg. The preferred embodiment of the connection is a slot formed in the long leg of the clamp unit into which fits a tab protruding from one section of the support unit.

Abstract: Vacuum cleaner canisters and vacuum cleaner filter bags are provided with weir members disposed in the path of particle laden air flowing through the vacuum cleaner. The particle laden air flows across the top and/or side edges of the weir members creating a pressure drop thereacross and an area of low pressure on the downstream sides of the weir members whereby particles in the airstream are influenced to drop out of the airstream and into the low pressure areas.

Abstract: A vacuum cleaner having a reduced velocity chamber with a high velocity air inlet, an electric motor, a rotary mechanism driven by the motor for creating a vacuum in the chamber, an outlet for exhausting air from the chamber, which air flows in a selected path from the air inlet, through the chamber and out the air exhaust outlet and a disposable porous sheet filter layer in the chamber for removing solids particles from the air. The vacuum cleaner also has a fiber filter between the filter layer and the motor where the fiber filter has an electrically charged non-woven material for removing very fine air particles in the chamber, intersecting the air path and generally coterminous with the disposable filter layer.

Abstract: A portable air cleaner designed to remove fine particles and unwanted gases from a room to provide for a healthier and cleaner environment. The portable air cleaner includes a high air volume circulating design and operates quietly and efficiently. The portable air cleaner is designed to minimize the unsettling of particles which have settled out on the floor about the base of the air cleaner so as not to aggravate the particle concentration within the room environment. The portable air cleaner includes a particle filter designed to have ultra high efficiencies with respect to particle removal. Disposed coterminous to the particle filter to remove unwanted gases from the filter air to provide for improved cleaner and healthier environment.

Abstract: A vacuum cleaner filter bag having multiple, nested inner bags and an outer bag for sequentially filtering a discharge from a vacuum cleaner, wherein each of the inner bags is adapted to cease filtering the discharge therethrough when the bag has become clogged with particulate matter. Each inner bag is designed to rupture, when clogged, in a manner to allow the discharge to bypass that bag and directly enter the next bag.

Abstract: A vacuum cleaner is provided comprising a canister including a chamber with an air inlet, an electric motor and a fan driven by the motor. The fan creates a vacuum in the chamber drawing air in a path from an air inlet through a filter located in the chamber, and out an air outlet. The vacuum cleaner includes a platform base, the base being detachable from the canister by a VELCRO fastening system.

Abstract: A vehicle window assembly which includes first and second separate window glazing panels. The first window is fixed while the second may be pivoted between open and closed positions by a hand crank connected to a peripheral linkage system by a shaft, with the linkage connected to the second window. The hand crank is located at the center of the shaft and the shaft includes stop means for preventing overturning of the hand crank past the full open position of the window.

Abstract: A window construction which is characterized by a sash frame hingedly mounted at the top of an opening in a generally vertical wall and provided with a latching mechanism comprising keepers on the inside face of the wall adjacent the bottom of the wall opening and a combination latch engaging and release bar pivotally mounted on the bottom of the sash frame so as to be swung into keeper engagement when the sash frame is hinged to closed position and to be readily swung to a position where the sash frame is released for opening movement.
