Abstract: An apparatus for fixing a sheet on the surface of an electrically conductive cylinder of a printing machine for processing sheets, in particular, a sheet-fed offset printing machine. The apparatus includes an electrode that extends over the width of the cylinder for creating an electric field for adhering the sheet to the surface of the cylinder and an air directing device for directing pressurized air streams against the sheet and preliminary positioning the sheet onto the cylinder prior to being acted upon by the electric field. Various alternative embodiments of the sheet fixing apparatus are disclosed.

Abstract: A sheet guide apparatus for use in a rotary printing press which is adapted for the smear and mark free transfer of sheets between two sheet holding and transfer systems, such as a pair of sheet-carrying cylinders or a sheet-carrying cylinder and circulating sheet conveyor. The sheet guide apparatus includes a sheet guide having a guide surface disposed beneath the transfer area, and a pneumatic system for blowing a positive pressure air stream in the direction of a transfer area or tangent point between the sheet holding and transfer systems. A further pneumatic system optionally may be provided for drawing or blowing air through apertures in the guide surface.

Abstract: An air assisted sheet guide device in a printing machine which is operable during either positive pressure (blast) air operation as well as suction air operation to permit reliable and stable sheet guidance with reduced air flow turbulence. The sheet guide device includes at least one module that defines a guide surface having air flow openings therein and an air flow channel, and a pneumatic system for creating either a positive or suction pressure generated air flow in the flow channel. One or more plate-like air directional elements are mounted within the air flow channel which create a uniform pressure distribution on the guide surface during positive (blast) air operation and which more uniformly direct air to the pneumatic system during suction pressure operation.

Abstract: An electric vacuum cleaner having a chamber arranged above the motor housing to receive a filter bag the side of which facing the motor housing is in valve-closed socket-connection communication with the fan-air channel and which can be removed from the chamber after opening and separating the socket connection. The filter bag is in socket-connection communication with a filter-bag intermediate support which is carried along upon the swinging open of the chamber and which has the valve-closure member and from which the filter bag can be separated somewhat on the other side of the vertical position of the cross-sectional plane of the socket connection.

Abstract: The invention relates to a vacuum cleaner nozzle that is provided with a latching device between the attachment stub and the nozzle housing. These elements are latched together in a defined swivelling range in such a way that they perform a common synchronized swivelling movement. The elements can be unlatched again by overcoming the action of a spring-loaded latching bolt.

Abstract: A bristle component is disclosed for a floor cleaning nozzle for vacuum cleaners. The bristle component includes a bristle holding strip mounted to the housing of the nozzle. The holding strip is provided with downwardly extending bristles at the corners or sides of the housing which are longer than the remaining bristles held therein. These longer bristles extend laterally from the sides of the housing as the nozzle is moved along the floor and sweep away dust from the floor in a corner defined by the floor and a surface extending upwardly from the floor such as the wall of a room or the like.

Abstract: The invention is directed to an attachment nozzle for a vacuum cleaning system such as a vacuum cleaner or the like which includes a rotating brush. A modular step-up gear transmission is interposed between the brush and the air turbine which runs in the suction air stream. The attachment nozzle includes an outer ring region wherein a plurality of air-inlet apertures are formed which are covered either partially or entirely by means of a ring-shaped body which is rotatably mounted on the end portion of the housing. A cup-shaped recess is formed centrally of the plurality of air inlet openings and defines a cup-shaped recess for receiving the modular gear transmission therein.

Abstract: A carpet cleaning device having brush rollers which extend cantilevered on both sides of their point of drive and are plug-engaged in head pieces rotating on a shaft, the head pieces being extended by coupling bushings which engage at their free end, by means of coupling claws, into mating claws of the hub of a drive gear which turns on the shaft.

Abstract: A floor care device has a rotary tool rotatable about an axis of rotation, a motor arranged to drive the rotary tool in rotation through a power transmission, and a supporting element formed as an angle lever which supports the tool, the motor and the power transmission and freely turns about a pivot axis which is offset relative to the axis of rotation of the tool in a substantially upright direction.

Abstract: A hand vacuum cleaner includes a housing having an inlet and an outlet, and a front and a rear part connectable with each other so as to constitute the housing. The housing has a front face and a rear face spaced from the inlet in the flow direction of incoming contaminated air entering the housing. A dust filter is located in the housing at the rear face thereof. A blower is located in the housing for aspirating the contaminated air into the housing through the inlet and into the dust filter and for urging the filtered air therefrom in a second direction towards the outlet. An intermediate plate is provided in the interior of the housing, which has a first formation constituting a first passage for the incoming contaminated air, a second formation constituting a second passage for guiding the filtered air from the dust filter towards the outlet and a third formation for fixing thereon the blower.
