Abstract: An electrical contact device including first and second switching contact units for producing or isolating electrically conductive connections, wherein a first contact side of the first switching contact unit is connected to a first contact side of the second switching contact unit, and a second contact side of the first switching contact unit is connected to a first connection contact of the contact device, and a second contact side of the second switching contact unit is connected to a second connection contact of the contact device, and wherein two switching contact units are designed to be actuable by a movable plunger acting on said switching contact units. The two connection contacts, in relation to the plunger, are arranged opposite one another on the contact device, and the first and second switching contact units are arranged within a mounting unit.

Abstract: A press for producing compacts from powdery material. The press has a die with a cavity that receives particles therein. A lower punch moves towards an upper punch to press the particles within the cavity. A cam disk moves the lower punch by way of a movable base-plate. Motion is transmitted through a sliding block to the base-plate and a cylinder having a piston causes movement of the die during at least a portion of the movement of the lower punch over its path of travel to the upper punch.

Abstract: A slide opening system for a tool system for compacting powdery materials having an upper ram, a lower ram and an insertable tool frame in which punch holders are moved relative to the base-plate from their filling position downward to the pressing position and from the pressing position upward to the ejection position which corresponds to the filling position (ejection method), and a further punch holder is moved from the filling position downward to the pressing position and from the pressing position downward to the withdrawal position (withdrawal method), with plungers acting on slides for releasing the withdrawal plate for the withdrawal motion, whereby the plungers of the slide opening system each act on a preferably stepped slide via a pivoted lever in the form of a cam disk with leverage that changes during the opening process and at least one roll located on the lever.

Abstract: In an isostatic press for making compacts of powdered cermaic material, a tool part has, on a sliding head, twice as many mold needles as mold parts which, together with the mold needles, limit molds for making the compacts. The distance between the mold needles on the sliding head is half the distance between the mold parts. The sliding head is moved back and forth in phases in the longitudinal direction of the row of mold pots by the distance between the mold needles, so that, at the same time as the produced compacts are lifted out and deposited on conveyor belts, the other mold needles are moved into the mold pots.

Abstract: In a press having an upper punch and lower punch and a tool mount to be inserted into the press and connected to the lower punch via a lower coupling plate and to the upper punch via an upper joining piece, and a framework mounted displaceably on a base plate of the mount and consisting of connecting rods rigidly connecting the lower coupling plate with the matrix holding plate, die carriers being moved relative to the base plate from their filling position downward into the compacting position and from the compacting position into the ejecting position, which corresponds to the filling position (the so-called ejection method), at lease one additional die carrier, like the matrix holding plate, works by the withdrawal method, this die carrier being moved from the filling position downward into the compacting position and from the compacting position downward into the withdrawing position.

Abstract: In a press for making sanitary articles, in particular toilet bowls, by pressure casting, mounting plates bearing the mold parts for forming the mold are suspended on slides along portals which extend radially outward from the center of the press. In the closed position of the press, suspension frames bearing the receiving plates are mechanically locked.

Abstract: A pressing tool for producing dish-shaped pressed objects, in particular plates, cups, bowls, etc.

Abstract: A vertically adjustable carrier for a vise comprises a vertical support tube and a mounting which can be secured to a work bench and which comprises two semicylindrical shells which embrace the support tube and which can be clamped together to fix the support tube in any desired vertical position. The shells extend downwardly from the mounting and define a cavity which accommodates a gas spring which abuts on one end on the support tube and on the other end on the bottom of the composed half shells and exerts an upwardly directed force on the support tube to ease its vertical movement.

Abstract: A vertically adjustable carrier for a vise or the like comprises a vertical support tube which is guided in a clamping device comprising two semicylindrical shells which can be clamped together. The shells are connected on one side by two support elements arranged vertically one below the other, and on the other side there is provided a clamping screw which is arranged between the horizontal planes through the support elements. By such arrangement a great resistance against unintended turning of the support tube even with a relatively slight tightening of the clamping screw is obtained.

Abstract: A vertically adjustable device for carrying a vise, an assembly platform or the like comprises a support tube which is vertically adjustably arranged within a guide tube arranged for attachment to a work bench or the like. In order to facilitate the vertical adjustment a gas spring is provided which acts between the support tube and the guide tube end exerts an upwardly directed force upon the support tube. The gas spring comprises a cylinder, a piston movable therein and a piston rod extending from the piston. The cylinder is arranged and held within the support tube so that upon removal of the support tube and the implement carried thereby by pulling the support tube out of the guide tube the gas spring is simultaneously removed leaving the work bench clear for other work.

Abstract: A sealing strip is composed of a holding part and a sealing part, the holding part being relatively resistant to bending and the sealing part being relatively flexible. It is made of a yielding, thermoplastic material containing a metallic reinforcing insert. The holding part (1) and the sealing part (2) contain separate, metallic reinforcing inserts. These inserts are interconnected in a manner permitting forces to be transmitted, by arranging for them to be jointly encased, by the thermoplastic material, in a connecting part (4) which can form a portion of the holding part (1). This is achieved by means of a process wherein the two metallic inserts are encased, with portions of their cross-sections located adjacent to one another, for example on passing through an extrusion die.

Abstract: A vise with conventional fixed and moveable jaws, a cylindrical support secured to the lower side of the fixed jaw, a mounting for attaching the vise to a bench or the like, a tube accommodating the cylindrical support for sliding and rotational movement, and a clamping arrangement on the mounting for clamping the tube and cylindrical support in place, is also provided with a gas spring within the tube. One end of the gas spring abuts the cylindrical support at its axial center while the other end abuts the sidewall of the tube exerting an upwardly directed force at an inclined angle which counteracts and offsets the tilting moment caused by the cantilevered jaws. The tube is formed with a portion of decreased diameter engaging the cylindrical support in the clamping zone, minimizing contact and friction, and preventing sticking or canting.

Abstract: A solvent which evaporates without leaving any adhering residue behind is used as a lubricant in the engagement of a clamping sealing strip on a retaining flange. At least some of the strip surface engaging the flange is made of a substance softened by the solvent and therefore enters into an intimate and possibly adhesive engagement with the flange. The strip can therefore be readily bent, yet sticks reliably.

Abstract: A profile strip of U-shaped cross-section is disclosed having two spaced apart arms connected by a base. The arms and base define a chamber for receiving a flange. An adhesion element is provided on at least one of the arms. The adhesion element is held against the flange when the profile strip is mounted thereon, and is further supported on a support surface connected to the one arm. During removal of the profile strip from the flange, the adhesion element rolls on the support surface tending to narrow the chamber.
