A working table for sheet-metal shears, principally for cutting large metal sheets, having adjustable stops mounted on brackets. On the edge of the working table, brackets which are perpendicular to the cutting edge of the sheet-metal shears are displaceably mounted in parallel with the cutting edge of the sheet-metal shears, while stop bolts which can be countersunk beneath the surface of the wor...

A hydraulic brake system for vehicles, particularly light rail vehicles, includes at least one brake actuator (39) and a pump unit (8, 9) for the supply of hydraulic fluid to the brake actuator. Means (6) are provided for controlling the rotational speed of the drive motor (8) of the pump unit in dependence on the required braking force to be supplied by the actuator.

Tags for agricultural use are made of plastics material, either 50-80wt.% low density polyethylene mixed with 20-35wt.% ethylene-vinylacetate copolymer in which the ratio of ethylene to vinylacetate is 70:30 to 80:20 and 2-10wt.% additives, or a mixt. of 50-80wt.% PVC with 20-50wt.% additives.

1. Self-tapping insert having an external thread (1), a chamfer (4) at the end of the insert (3), which cuts the external thread (1), and also having notches (5, 10, 12) in the region of the chamfer which form thread-cutting edges which cut an internal thread there in a smooth receiving bore when the insert is tapped, the inset has a bore passing over its entire length having an internal thread (2...

1. Self-tapping screw insert having an external thread (1), the thread base of which is a constant distance from the axis of the screw insert, having a conical path at the insert end and having notches (3), running roughly radially, in the region of the conical part of the screw insert, the rear edges of which, when viewed in the tapping direction, together with the outer thread (1) cut there form...

The bearing sliding surface of the sliding journal bearing is composed of two surface parts of two circular cylinders whose axes are located at a distance apart. A diametral plane defined by the two axes of these circular cylinders includes, together with a horizontal plane through the bearing axis, an angle of approximately 35 DEG . At least one oil supply hole enters into each bearing bore under...
