Abstract: Ein pneumatisch angetriebener Anschlag für vorgeschobene Werkstücke weist einen Pneumatikzylinder (4) mit einer verschieblichen Kolbenstange (6) auf, an welcher ein Anschlag (12) befestigt ist. Ein mit der ausgefahrenen Kolbenstange zusammenwirkender Endanschlag (11) legt die Sollstellung  (S) des Anschlages fest. Ein Präzisions-Grenztaster (17) zum Abfühlen der Sollstellung (S) des Anschlages (12) liefert beim Herausbewegen des Anschlages aus seiner Sollstellung ein Schaltsignal. Von diesem Signal wird ein mit dem Pneumatikzylinder (4) verbundenes Ventil (8) gesteuert, welches den Zylinder drucklos mit der Atmosphäre verbindet, wenn der Anschlag in Sollstellung ist und noch kein Werkstück an ihm anliegt, welches den Zylinder mit Druck beaufschlagt, sobald der Anschlag durch ein vorgeschobenes Werkstück aus seiner Sollstellung herausbewegt ist, so daß der Anschlag unter Mitnahme des Werkstückes in die Sollstellung zurückkehrt, und welches diesen Druck während vorbestimmter Zeit aufrecht erhält.

Abstract: A microcomputer system including a master processor and a coprocessor interconnected via a bus is disclosed. The coprocessor supplies first, second and third signals to the master processor, the first signal taking an active level when the coprocessor requests a wait condition of the master processor, the second signal taking an active level at when the first signal is changed to the inactive level in a state of occurrence of arithmetic exception in the coprocessor, and the third signal taking an active level when the coprocessor is free of execution of an instruction and of occurrence of the arithmetic exception. When the coprocessor executes an instruction whose execution result is not required to be returned to the master processor, the master processor detects the level of the third signal and if the third signal is at the active level, the master processor starts to execute subsequent instructions irrespective of the first and second signals, in parallel to the execution of the instruction by the coprocessor.

Abstract: An indirect liquid heating system comprises a water tank (20) having an inlet (5) and outlet (7). A fuel gas burner (1) below the tank discharges products of combustion through heat exchanger tubes (2) to a smoke box (10) above the tank, from whence they are vented from a flue( 8). 
     According to the invention the part (3) of the tank bottom (21) immediately above the burner (1) is conical or pyramidal, its tip or apex (24) projecting into the orifice of the inlet (5) so as to restrict the same and cause local increase in the speed and pressure of incoming liquid. In the case of raw water this will inhibit scale formation. Scale which does form on the cone or pyramid (3) is shed by differential contraction and expansion and falls down the sloping surface(s) of the cone or pyramid (3) to collect at the bottom (21) of the tank at a position laterally offset from the burner (1), thus avoiding overheating of the tank bottom and inefficiency due to scale accumulation.

Abstract: Brake pad, especially for calliper disc brakes, having a damping plate (1) arranged between a retaining spring (3) and a brake shoe (2), the damping plate being secured on  the brake shoe against displacement and distortion. To secure the damping plate (1) against distortion or displacement on the brake shoe (2), the invention provides that the damping plate (1) is held in a positive and non-positive manner on the brake shoe (2), the damping plate (1) preferably interacting with the retaining spring (3). Conventionally used damping plates (1) have the disadvantage that, in spite of the corresponding moulded-on parts for fastening to the brake shoe (2), there is inadequate securing against distortion and/or displacement, as a result of which damage to the damping plates (1) and adjacent parts is not eliminated.
