Title: Castor which can be decelerated and is intended for a load-receiving, moveable supporting plate
Inventor: LEHR LOTHAR
IPC: B60B33/02
Filed: 1986-05-31
Abstract: The invention relates to a castor which can be decelerated and is intended for a load-receiving, moveable supporting plate, in which in a U-shaped bearing block a wheel is mounted such that it can rotate around a horizontal pivot, in which the bearing block can be swivelled around a vertical bearing bush in which an adjusting pin is guided in an axially adjustable manner, in which the adjusting pin protrudes by its operating end over the top side of the supporting plate and is held in the non-actuated initial position by means of a first compression spring, in which the lower end, projecting out of the bearing bushing, of the adjusting pin controls a braking element which prevents the rotation of the wheel when the adjusting pin has been adjusted, and in which the adjusting pin is held in the actuated position by means of a releasable locking device. On the adjusting pin, above the supporting plate, a locking lever which is loaded by means of a further compression spring is applied to the adjusting pin and automatically blocks the braking position of the adjusting pin. On operating the locking lever the blocking of the braking position is cancelled and the adjusting pin is automatically returned into its initial position.

Patent DE-3723824-A1 (DE)
Inventor: GROOS HORST
IPC: B21C35/02
Filed: 1987-07-18
Abstract: The strand produced in a bar or tube extrusion press is drawn off with a controlled tensile force which keeps the emerging strand taut but should not influence the formation of the said strand. In order to keep constant the tensile force acting on the strand in the die zone, the procedure according to the invention is as follows: superimposed on this tensile force (draw-off force) matched to the cross-section and flow behaviour in the die is a tensile force (tractive force) which increases in proportion to the length of strand extruded and takes account of the weight per unit length and the coefficient of friction between the strand and the run-out table. The particular method adopted for this purpose is as follows: after a strand has been cut off and removed from the die, the tractive force and the length of the strand delivered are measured and the tractive force divided by the strand length is input as the specific profile friction force to be multiplied by the strand length, the latter being determined by displacement measurement, when a subsequent strand of the same desired cross-section is extruded. Control is carried out as follows: the desired value determined and input for the tensile force exerted on the tip of the strand is, in addition to a value taking into account the resistance to motion of the carriage of the drawing-off device, as the first summand, and a strand cross-section-dependent base value of the draw-off force, as the second summand, an increasing value, the respective product of the result of continuous delivery path measurement and predetermined specific profile friction force between the emerging strand and the run-out table, as third summand, beginning with the grasping of the tip of the strand by the grippers of the drawing-off device.
