Abstract: A device for collecting, compressing and discharging loose material, the device being formed from a body of flexible material having a self-sustaining, scoop-shape. The body has a flat bottom, lateral sides, and an open top. The bottom merges with the lateral sides at one of the ends of the body to form a flat edge thereat, and at its other end, the body has an end wall extending upright from the bottom. The lateral sides have upper edges extending from the flat edge upwardly to an upper edge of the end wall thereby defining an open, interior cavity adapted for receiving loose material therein. The lateral sides and the bottom are joined to the end wall by fold lines forming stabilizing corners which provide the self-sustaining shape of the body while the flexible material of the body allows the lateral sides to be overlapped on one another to compress and confine the loose material in the cavity.

Abstract: An apparatus for cleaning a wafer oriented vertically is provided. The apparatus includes a first brush and a second brush located horizontally from the first brush. During use, a wafer is orientated vertically between the first and second brushes. The brushes are brought into contact with the wafer and rotated thereby engaging the wafer with rollers. By rotating the rollers, the wafer is also rotated. Liquid is sprayed towards the brushes and wafer. By orienting the wafer vertically, liquid and particulates contained therein readily fall from the wafer due to gravity. This is particularly advantageous when cleaning larger diameter wafers in which particulates must be removed from a larger wafer surface area.

Abstract: A replaceable head toothbrush is described having a handle, a brushhead and a collar. The handle is formed with a cavity within which the collar is insertable. The brushhead at an end thereof is formed with a neck having a coupling anchor for engaging a complementary disengaging mechanism within the collar.

Abstract: A drive disk for the rotary tool of a machine for conditioning and/or maintaining floors includes a rigid circular plate and a circular diaphragm. In accordance with the invention, the drive disk includes a sealed axial passage passing through it and discharging at one end via a first central orifice in said rigid circular plate and at the other end via a second central orifice in said diaphragm.

Abstract: A buffer brush for stenciling with which the user's hand will not get tired even if it taps the handle for a long time to stencil ink, and the close contact of the ink absorbing part and the stencil will be good. The buffer brush comprises an ink absorbing part (2) on a handle (1) which is made of buffer material.

Abstract: A device for extraction of vacuum-cleaned material comprising a propellant ozzle (1) operated by propellant gas that has on a suction side a vacuum tube (4) with vacuum tool (20) on the end for extraction of vacuum cleaned material and on a discharge side is connected to an extraction pipe (9) leading to a suction and filtering system, wherein means (5,6) to automatically trigger a function switching on said propellant nozzle (1) when said vacuum tool (20) is removed from its rest position and that automatically trigger a function switching off said propellant nozzle (1) when said vacuum tool (20) is inserted in its res position into a mounting (7) into which a plunger (6) of a valve (5) controlling the propellant gas slidably projects.

Abstract: The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) is received which is mounted so as to be rotary about a longitudinal axis (3) and is adapted to be driven in an oscillatory fashion. Further, the brush section (1) includes a bristle supporting structure (11) which is arranged so as to be rotary about a transverse axis (14) by means of a bearing pin (18) and is adapted to be set in a rotational motion (29) about said transverse axis (14) by means of a drive pin (24). The fixed connection between the bearing pin (18) and the shaft (7) has the added effect of causing the bristle supporting structure (11) to perform a pivotal motion (28) about the longitudinal axis (3). The rotational motion (29) of the bristle supporting structure (11) produces a cleaning action on a user's exposed tooth surfaces, whilst the pivotal motion (28) acts to accomplish an additional cleansing operation on the user's inter-proximal surfaces.
