Abstract: An auxiliary device for processing a flat surface of a workpiece, particularly a plate-like workpiece, includes a ruler-like base rail with at least one guide formed by a profiling of the base rail for slidably connecting a support plate with a recess for exchangeably mounting an electrical processing apparatus. The recess of the support plate has at least one adjustable and lockable stop for the processing apparatus.

Abstract: A device for generating angles has a ruler-shaped basic rail having a first guide extending in a longitudinal direction of the basic rail. A stop rail is arranged in the first guide of the basic rail and is rotatable and slidable into different positions relative to the basic rail and securable in the different positions. The stop rail has an underside provided with depressions positioned at an acute angle to one another and forming a star-shaped arrangement. The basic rail has a projection that engages the depressions.

Abstract: A device for positionally accurately guiding cup drills, particularly for producing blind-end holes for cup hinges in plate-shaped structural components composed of wood or a substitute wood material, is composed of a U-shaped base body which can be placed on the plate-shaped structural component. The base body has in one leg thereof a tightening screw and in the other leg a carriage with a guide opening for the cup drill, wherein the carriage is displaceable relative to the web and can be clamped against the plate-shaped component.

Abstract: The invention is directed to a jig for boring doweling holes into alignment with one another in two boards or the like to be connected with one another by dowels or pegs and adhesives or bonding, comprising a plate which can be placed upon the board to be drilled, said plate comprising at least one guide hole for a drill and an adjustable and removable stop. In order to achieve elimination of the hitherto required insertion and removal of the dowels or pegs into or from the dowel holes of a board for positional determination of the bores in the second board, a displaceable or adjustable centering pin 14 probing the dowel hole 16 of the already drilled board 1 in an aligned manner is allocated to the guide hole 9.

Abstract: An air cargo pallet in which a square or rectangular thin light metal plate is trimmed along its edges by profiles which are riveted to the edges of the plate and have miter cut sections adjoining at the corners. Shear is resisted at the junctions of the miter cut sections by insert parts which are flat, elongated and fish shaped and which have a pointed end and a recess at the opposite end, each defined between flanks forming a vertex at 90.degree. and braced between internal and external corners of the walls of a hollow space within profiles.

Abstract: A vise is combined with a C clamp and the C clamp is fitted with at least 2 plug members fitting into receiving holes in the vise or in the C clamp, there being a larger number of holes than plug members whereby the C clamp, plugs and holes permit various orientations of the vise on a work bench.
