Title: Gripper for lifting hollow or solid section esp. aluminium@ bar - has two clamping rings pivoted scissors fashion and whose bore edges grip bar end symmetrically and prevent tipping as it is lifted vertically
Inventor: MOERS FRIEDHELM VON DIPL ING
IPC: B66C1/42
Filed: 1992-08-22
Abstract: Two arms (24,26) are suspended by crossed-axes pivots (46,54) from a lifting beam (12). On pins (64) at the bottom of each arm are pivoted two clamping rings (18) with oval bores which are large enough to allow the rings to pass over the end of the bar to be lifted (30). The rings are connected scissors-fashion with a pivot (60,62) allowing rotary and some linear movement. When the catch (76) is released the wight of the clamping rings causes them to close onto the bar (30) and the opposite edges (70,72) of the bores to bite into the bar surface. When the bar is lifted the gripping force is magnified and the line of action of the lifting force is down the bar axis thus preventing tipping. USE/ADVANTAGE - Safe and reliable handling of hollow or solid-section aluminium bar.

Title: Method and device for joining wooden components by means of a junction plate
Inventor: MOSER KARL DIPL ING
IPC: B27C3/06
Filed: 1993-05-06
Abstract: In order to drill junction-plate connections in wooden components, it is proposed that the junction plates (1), which are composed of metal, be drilled through the wooden components (3) in one operation using a stepped twist drill (13). The stepped twist drill (13) has first cutting edges which pilot-drill the junction plate (1), whereas a thicker shank portion of the stepped twist drill (13) is guided in the wooden component (3) and removes metal chips without drill-hole damage on the wooden component (3). On widening the drill holes in the junction plate (1), comparatively narrow metal chips are produced which, in turn, can be removed without any problems through the chip-removing grooves of the thicker shank portion of the stepped twist drill (13). Preferably, multi-spindle drilling machines (31) are employed to drill-hole patterns. In order to avoid vibrations upon insertion of the rod dowels (7) which connect the junction plate (1) to the wooden components (3), these rod dowels are expediently driven in by hydraulic pressure tools. <IMAGE>

IPC: G05B11/42
Filed: 1993-07-05
Abstract: The invention relates to a controlling device with PID control component by means of which a controller output value (u) can be obtained from the control difference (Xd), with an actuator (5) with correcting variable limitation forming a correcting variable (y) from the controller output value (u) and a switch (4) by means of which the control difference (Xd) is taken to the PID control component as a controller input value (r) if the correcting variable (y) determined by the controller output value (u) lies within its setting range and by means of which an auxiliary value (e) is taken to the PID control component if there would be an ideal limitless correcting variable owing to the control difference (Xd) outside the setting range. The auxiliary value (e) is determined in such a way that the correcting variable (y) still lies within its setting range. This prevents a rise in the I component if the reference value (y) lies within the limits concerned. The invention is used in controllers.
