Patent DE-3340761-A1 (DE)
Title: Device for transmitting an electrical voltage from the location of a machine-tool controller to the location of an associated machine tool
Inventor: KOLLER KLAUS DIPL ING
IPC: H04B3/02
Filed: 1983-11-10
Abstract: Single-pole electrical voltages (UE1) are supplied as the information carrier from a machine-tool controller (WST) to a machine tool (WM), in each case via a control line (SL). A balancing line (SL) which carries reference potential at the location of the machine-tool controller (WST) is, furthermore, used for the supply between the machine-tool controller (WST) and the machine tool (WM). Voltage amplification takes place at the location of the machine-tool controller (WST), using a differential amplifier (D). Said differential amplifier (D) is supplied, on the one hand, with the voltage (UE1) to be transmitted and, on the other hand, with an auxiliary voltage (UE3). The magnitude of the auxiliary voltage (UE3) is in this case a fraction (determined by the gain factor (k) of the differential amplifier (D)) of the voltage drop (UL) occurring on the balancing line (AL). This results in the ratio of the value of the voltage (UE2) at the location of the machine tool (WM) to the value of the voltage (UE1) at the location of the machine-tool controller (WST) corresponding to the gain factor (k) of the differential amplifier (D), irrespective of the balancing currents into the balancing line (AL). <IMAGE>

Title: Method for driving a pump for concrete or the like, and a pump for implementing the method
Inventor: MUELLER EBERHARD
IPC: F04B9/117
Filed: 1985-02-18
Abstract: The invention relates to a method for driving a pump for concrete or the like, comprising two drive cylinders which can be made to move in opposite directions in a reciprocating manner, as a rule by means of a fluid, and whose pistons are mechanically linked to the pistons of the working cylinders via a servo cylinder driven by pressure cylinders. The object of the invention is to describe a method according to the definition given which reduces the noise level to a minimum. This object is achieved by providing each of the two drive cylinders (1/2), at one of their end sections (1.1/2.1) facing away from or towards the working cylinders (7.1/8.1), with hydraulic connections (9/10) which, as the pistons (3/4) pass over them, produce, via a control pulse initiated in each case by a pressure switch (13/14), a reduction of the piston travel of the servo pump (16) and thus of the pumping capacity, which reduces the drive speed of the pistons (3/4) before they reach their respective end stops, and by the piston (3/4) in the final position, upon reaching maximum pressure, emitting a pulse for the pressure-controlled servo pump (16) to swing out, driving it, at full pumping capacity in each case, into its opposite end-position regions and, at reduced pumping capacity, into its end position. <IMAGE>
