Abstract: The present invention relates to a drawer side made of metal. The drawer side includes a double-walled upper profile section bent from sheet metal and open at the bottom, into whose open bottom a bottom profile section (14) which is separately made and joined to the upper profile section is inserted, so that the drawer side is formed by a closed hollow profile. The bottom profile section (14) is inserted into the open bottom of the double-walled upper profile section (12) bent from sheet metal. The bottom profile section is made of plastic, preferably by an injection molding process from a thermoplastic.

Abstract: A fire detector includes a scattered light detector unit and an ionization detector unit which are arranged upon a common base at each side of the center axis of a compartment defined by the base and a peripheral wall extending from the base. The scattered light detector includes a light source and a receiver, with their principal axes intersecting in a point of intersection which is positioned at one side of the center axis of the compartment and thus extends eccentric to the center axis. The ionization detector unit includes a holder for a preparation to be ionized, with the holder being arranged at the other side of the center axis. Suitably, a heat detector is further provided in the center axis.

Abstract: A mounting system for the carcase-interior end of the guide rail (10) of a drawer guide for drawers and the like in the carcase of a cabinet at a distance from the inside surface of the associated carcase side wall. The guide rail (10) is formed as a channel which is fitted from underneath into a corresponding runner rail which can be fastened to the drawer and is formed by an inverted channel inside of which tracks are formed for rolling bodies. In the portion of the guide rail (10) engaged in the runner rail, tracks are also formed for the rolling bodies, so that the runner rail is displaceable relative to the guide rail. The section of the guide rail (10) engaged in the runner rail is bent from the horizontally disposed web of the rail. In the carcase-interior end portion of the guide rail (10) a tab (16) stands up from its horizontal web and is aligned transversely of the length of the guide rail, and is provided with detent teeth (18) on its edge pointing away from the web.

Abstract: An automatic pull-in mechanism for drawer guides consists of a guide rail and a runner rail, which are made longitudinally displaceable relative to one another by rolling bodies. On the guide rail there is disposed a component that can toggle between two end positions and is biased bistably toward the toggle end positions by a spring system, and has an open-ended slot for a projection projecting downward from the runner rail. The projection and the toggling component are so disposed relative to one another that upon a displacement of the runner rail from the drawer-open position to the drawer-closed position, as the projection approaches the latter it enters into the slot and then, after passing over the dead center of the toggling component, it is carried resiliently by the slot into the drawer-closed position.

Abstract: An ionization fire detector of the type including a measuring chamber and a reference chamber having a common electrode which is connected to the gate terminal of a field-effect transistor by a profile piece of conductive caoutchouc having one end contacting the gate terminal and another end contacting the common electrode.

Abstract: The invention relates to a preferably hollow metal stock for drawer sides, especially drawer sides, and to a method for the production of such hollow stock. The hollow material has a hollow space which is foam-filled, to improve the properties of the action of a drawer made from the stock by reducing the noise that occurs when a drawer is opened and closed. The strength of the stock is also improved and as is a drawer made from the stock.

Abstract: A rotary punching machine comprises a pair of punching tools, namely a rotary punching tool with punches arranged on its circumference and a rotary counter tool, which co-operates with the latter, with dies in the form of punching bushings arranged on its circumference. One of the punching tools (1) and the counter tool (3) has a radial groove (12) on its circumferential surface between the respective individual punches (2) or the individual punching bushings (4), the depth of the groove being greater than the depth of penetration of the punches (2) into the punching bushings (4).

Abstract: The present invention relates to a metal panel for drawer walls. The invention provides for a single thickness wall plate stamped and shaped from sheet metal and a separately manufactured drawer-bottom holding shaped structure formed of metal. The wall plate has a lower marginal area which the drawer bottom holding shaped structure is fastened to.

Abstract: Mounting bracket (10) for the rearward end of the runner (18) of a drawer guide (20), in which the guide rail (22) to be fastened to the cabinet wall reaches from underneath into the corresponding runner (18) which is formed of a hollow structural shape open at the bottom and is to be fastened removably underneath the drawer bottom (16); a front mounting piece which can be mounted under the drawer bottom (16) in the area of the drawer front is associated with the front end of the runner (18), on which the outer end of the runner is releasably held.The mounting bracket (10) to be fastened in the rear corner area of the drawer has two clip arms (36) projecting downward below the underside of the drawer bottom (16), at least one of which clasps the runner (18), and between which the runner can be passed.

Abstract: The invention relates to a fastening hardware set for the adjustable fastening of a drawer front to the sides of a drawer. The invention has a hook which can be affixed to the front mark. A stud unit which can be releasably held by the hook is provided on the corresponding side.

Abstract: A corona treatment of web-shaped materials or shaped bodies is performed by at least one corona electrode which has an operating region, wherein a gas and/or waste heat produced during the corona treatment is aspirated and at least partially returned to the operating region of the corona electrode.

Abstract: A drawer side panel having an upright front edge flange formed with at least one throughgoing hole and normally extending parallel to a back face of a front panel which itself is formed with a pair of vertically spaced bores are secured together by a vertically elongated anchor unitarily formed with a pair of forwardly projecting inserts engaged in the bores of the front panel. A vertically elongated adaptor between the flange and the anchor is formed with at least one horizontally elongated hole aligned with the hole of the side-panel front flange and projects horizontally past the front flange. The adaptor has formations permitting itself to move vertically on the flange while preventing itself from moving horizontally on the flange.

Abstract: An apparatus for manufacturing a brush-type seal comprising wrapping a filament over two spaced elongated mandrels in parallel arrangement to form a filament packing, then securing the filament packing at its ends onto the two mandrels, thereafter dividing the filament packing in a median plane between the mandrels to produce two brushes which are then bent into the desired brush shape. The bristles can be formed at an inclination in their mountings by supporting the mandrels on the base beams of a parallelogram linkage which can be displaced and controlled by cam disks so that the length of winding of the filament remains constant.

Abstract: Separate segments, oversized to allow for shrinkage during welding, are assembled in the shape of a ring. The segments may be plates carrying guide vanes. The assembled ring is placed in a vacuum chamber and the joints between segments welded by an electron beam. The welding may be carried out in two steps, namely, first track welding the segments together followed by finish welding the entire length of each joint. The segments may be held during welding in a fixture comprising a circular array of radially-slidable jaw elements which carry the separate segments. A clamping ring urges the jaw elements, and hence the segments, radially inwardly, and a cover plate engages the separate segments and urges them radially inwardly so as to clamp the segments together in a ring shape.
