Abstract: In a weighing cell a load receiver is constrained in a mode of planar translatory motion in relation to a stationary part (1). The stationary part (1), configured in the shape of a solid H-profile, has two side plates (3) to which the guide links of a parallelogram mechanism are attached. A base plate (2) connects the side plates (3) and supports the parts, that are required for transmitting a force to be measured from the load receiver to a measuring cell. The force-transmitting parts can be configured either as a monolithic material block or as individually assembled components. (FIG.

It is an object of the present invention to provide a tool which allows the exact cutting of those boards in a time saving manner. According to the present invention this object is performed by a tool for working board-like workpieces, in particular sandwich type plaster boards, comprising a guide means for guiding the tool, a handle means, a blade means for forming a cut in the workpiece, and a coupling means for coupling the blade means with the guide means in an adjustable manner. A spacing between the handle means and the blade means may be adjusted by said coupling means in a direction transversely to a moving direction of the blade means.

Abstract: Certain ulcers and disease conditions resulting in tissue destruction, such as those found near the cornea of the eye, and those found in the stomach, and damaged joint tissue of rheumatoid arthritis, have been found to be caused by the enzyme, collagenase. A collagenase inhibitor, such as cysteine, ethylene diamine tetraacetic acid (or sodium ethylene diamine tetraacetate), or combinations of these collagenase inhibitors, are used to treat such ulcers and to inhibit further formation thereof.

Abstract: A container for receiving and displaying elongated articles of different diameters such as drill bits and the like is disclosed including a generally rectangular dish-shaped receptacle having a horizontal bottom wall and opposed pairs of upwardly extending side and end walls, and a generally rectangular dish-shaped cover member having a horizontal top wall and opposed pairs of downwardly extending side and end walls, the cover member including pockets for retaining the elongated articles and the lower surface of the receptacle bottom wall containing a plurality of recesses having different diameters corresponding with the diameters of the articles.

Abstract: A centrifugal drum apparatus for finishing the surfaces of metal objects is disclosed, including a housing, a disk-shaped rotor member connected with the housing for rotation about a generally horizontal axis, and a plurality of finishing drums open at one end and having longitudinal axes arranged symmetrically about and parallel with the rotor axis, the finishing drums being rotatably connected with the rotor member. The apparatus includes a first drive assembly for rotating the rotor member about the horizontal axis, and a second drive assembly for rotating the finishing drums about their longitudinal axes. When metal objects are placed within the finishing drums and the rotor member and finishing drums are rotated, the surfaces of the metal objects are ground and polished through abrasion with the inner surface of the drums.

Abstract: Two receivers arranged inside and outside a closed space, respectively, are responsive to ambient or environmental noise and a comparator provides an alarm signal when the difference between the outputs of the two receivers falls below a threshold, thereby indicating that the wall to the space has been breached. Alternatively, the two receivers may be arranged in spaced relation within the space and the comparator provides the alarm signal when the difference between the two outputs rises above a threshold, thereby indicating that an intruder is present and closer to one receiver than the other. The apparatus consumes little energy during the watch period and does not depend on itself radiating energy.

Abstract: A metronome is disclosed including a casing accommodating a driving device for a pendulum, the casing having an elongate trough-like body covered by a cover plate. The driving device is mounted on the inside of the cover plate. An imprinted scale plate associated with the pendulum is mounted on the outside of the cover plate. The pendulum is fixed on a shaft mounted in a bridge on the cover plate and driven by the driving device. Two screws fix both the bridge and a frame of the driving device to the cover plate. Holders integrally formed on the inside of the cover plate, at a location spaced above the fixing screws, engage with and retain the frame of the driving device. The scale plate can thus present a wide uninterrupted surface on which tempi and beat rates can be imprinted and related to each other.

Abstract: A clamping device for clamping to a parallel sided support, e.g. a desk top or shelf comprises an elongate base on which is rigidly mounted a first arm. A second arm is slidable on the base and carries a screw which engages the rear face of the base to define a pivot axis. A second screw is manually rotatable to engage the base and pivot the arm about the pivot axis until the edge of the face plate engages the base to lock the arm in position. By suitable pre-setting of the screw the arm locks when the face plates are parallel. The clamping device may be used to support a microfilm projector.

Abstract: A method is disclosed for producing extrusion profiles of a desired length, including the steps of processing a billet of preselected billet length in a press, measuring the extruded length during the extrusion process, and either switching off the extrusion process upon reaching the desired extruded length and varying the billet length such as to obtain the optimum butt thickness, or switching off the extrusion process upon reaching the minimum permissible butt thickness and enlarging the billet length such as to obtain the desired extrusion length. The apparatus for performing the method includes a billet hot shearing unit which has an adjustable longitudinal feed stop and cuts the billets to length. The billets are supplied to, and are processed in, a press in which a first length recorder measures the butt thickness and from which the extruded profile is drawn out by an extrusion drawing unit. A second length recorder measures the extrusion length.
