Abstract: Wood screw for predrilling-freely inserting into a wood base, in particular into a massive wood base, wherein the wood screw comprises a shaft portion with a thread which is self-cutting in wood, a screw head which is connected to the shaft portion directly or indirectly at a back side, and a screw tip which is connected to the shaft portion directly or indirectly at a front side, for predrilling-freely penetrating into the wood base, wherein at the shaft portion between neighboring thread turns, portions are formed which taper towards the screw tip.

Abstract: Screw for introducing into an underground, comprising a screw shaft and a screw head which is adjoining the screw shaft, in which a drive is formed for rotary driving the screw by a drive element, wherein the drive comprises a hollow wing section at an outer side of the screw with a circular hollow core and hollow wings which are provided along the circumference, wherein the drive comprises a hollow recess section at an inner side of the screw, and wherein the drive at a transition between the hollow wing section and the hollow recess section comprises a chamfer section whose outer surface is angled with respect to an outer surface of the hollow wing section and with respect to an outer surface of the hollow recess section.

Abstract: A case for holding tools or small parts includes a basic body and a lid coupled pivotably to the basic body. The basic body has two side walls, the upper edge of which is exposed in the closed state of the lid, and therefore the lid, in the closed state, is arranged between the upper edges of the side walls of the basic body. Each side wall of the basic body forms a labyrinth seal with the respective side wall of the lid in the closed state of the case.

Abstract: An arrangement for removing dents from sheet metal contains a lever, which at a support point can be supported on the metal sheet. A handle is fitted to the lever end. To the lever can be connected a tension element, which can be connected to an adapter connected to the metal sheet.

Abstract: The invention relates to a handle for a hand tool and a method for the manufacture of the handle. The problem of the invention is to provide a handle for a hand tool, whose surface is formed from areas of distinguishable materials and which simultaneously has a good and pleasant grippability. A handle according to the invention for a hand tool, particularly a turning tool, is made from plastic. It has a surface from flush-connected areas of distinguishable materials. The two materials can be distinguished from one another.

Abstract: A stud driver for driving fastener studs in place with the aid of a propelling piston moved by a propellant contains a return spring concentrically surrounding a piston rod of the propelling piston. The return spring has roughly the shape of a relatively thin-walled cylindrical sleeve of elastomeric material reinforced at regular intervals by metallic ring disks. These metallic ring disks prevent any uncontrolled deformation of the elastomeric sleeve in high-speed movement of the propelling piston.

Abstract: A knock-in pin dowel contains a dowel shell with a non-expandable shaft part located on the outside and an expandable part connecting thereto. The expandable part is subdivided into two axially following or overlapping expandable areas, which are in each case formed by longitudinal slits and expandable segments remaining between said longitudinal slits. The two ends of the longitudinal slits of the first expandable area are closed, whereas the longitudinal slits of the inner expandable area directed towards the inside of the drilled hole are open at the dowel end.

Abstract: A tool for removing adhesive residues, films or the like from a metal surface contains a shank, which can be rotated by a drive mechanism. A disk made from rubber or a plastics material is clamped in non-rotary manner to the shank.

Abstract: A refillable distributing container for liquid media, particularly an aerosol can, has two valves, whereof an upper valve is constructed as the distributing valve (5) for exclusively distributing the container content. The second valve is constructed for filling the container both with liquid medium and with pressurized gas. The invention also relates to a filling device for refilling the distributing container and a process for the same. The filling device has a filling connection (9), which is connectable with the distributing container filling valve (8). The liquid is preferably forced in to the distributing container with the aid of the pressurized gas.

Abstract: Apparatus for making available tools and materials contains a frame, which is formed from a lower frame element and uprights fixed thereto. Closed storage containers for tools and materials can be individually fitted to the frame. The storage containers can be matched to the specific use. The apparatus contains at least three bearing points, which are preferably formed by rolls or wheels.

Abstract: At the end of am accumulator discharge process, the accumulator has a raised internal temperature. In order to be able to recharge it again, it is necessary to wait until it has cooled. The charging time is consequently significantly determined by the cooling time. To shorten the charging time, the invention proposes the installation in the accumulator of a temperature sensor and disconnecting the accumulator on reaching a predetermined temperature. Although it is still not empty, it then supplies no further current. However, it can immediately be recharged, so that the cooling time is rendered superfluous. Despite the shorter discharge time, the accumulator is consequently available over a longer period of time.

Abstract: An apparatus is provided for delivering assembly and machining expendable materials or tools. The apparatus has an internal continuous mechanism with different compartment rows arranged in rotary manner and to move past a removal door row. An embodiment having relatively stationary compartments and movable doors to align with a selected compartment is also disclosed. An inputting keyboard for the positioning of the particular compartment row in front of the removal door row also controls the unlocking of a door in the door row associated with the selected compartment. The delivery unit is connected by means of a long-range transmission means to a data processing unit, which records the removal of the materials and optionally initiates reloading, billing, etc.

Abstract: For its drive a screw is given a recess, which has an outer contour diverging from the circular shape. In the radial inner area and/or radial outer area of the recess the side walls are formed by individual surfaces located on a conical surface.

Abstract: In a double chamber container, the inner chamber is formed by a tubular body of an elastic rubbery material stretched in order to expel a pressurized substance against its own elasticity. To obtain a precise stretching ratio of the tubular body and to empty it as well as possible, the tubular body converges uniformly and its walls have a uniform thickness, even in their bottom part. To attach the tubular body to the container, a collar which acts also as a seal is formed on the thereon. A process for producing the tubular formation includes bringing an elastomeric material into the flowable condition and coating it over a mandrel, and applying a cooling medium detachable from the mandrel over the mandrel initially and/or applying a treatment medium detachable from the mandrel over the latter subsequently, for the controlled alteration of the surface on the mandrel side of the elastomeric material.

Abstract: The apparatus is provided for delivering assembly and machining expendable materials or tools. It comprises an internal continuous lift mechanism with different compartment rows arranged in rotary manner to move past a removal door row. An inputting keyboard for the positioning of the particular compartment row in front of the removal door row also controls the unlocking of door in the door row associated with the selected compartment.The delivery unit is connected by means of a long-range transmission means to a data processing unit, which records the removal of materials and optionally initiates reloading, billing, etc.

Abstract: A screw has a thread (3), whose front and rear flanks have a different angle with respect to the screw longitudinal axis. The screw tip (2) can contain a scraping groove (6), which extends as a notch in the screw longitudinal direction. In the front, conically tapering area of the screw the thread course is constructed symmetrically and extends up to the tip.
