Hydraulic drawing system in a single or double working press

Abstract: The present invention relates to a hydraulic drawing system in the press table of a single- or double-acting press, the drawing ram (7) being mechanically driven and the drawing system being suitable for two different operating modes selectable upon tool change, more specifically for operation with a tool (3) situated in the middle of the drawing station or with two tools arranged in parallel in the direction of material feed, the pressure-plate force being adjustable at each of the four corner points during the descent of the ram. The object of the invention is to simplify the switchover from operation with a central tool (3) to with two tools (3) per drawing station arranged in parallel in the material feed direction. In both operating modes, the counterforce applied during the descent of the ram is applied at each of the four corners of the pressure cheeks (9) via flexible pads. Adaptation to the individual operating modes is effected by connecting up or disconnecting the various pressure cylinders.

Mobile telephone e.g. for monitoring sleeping children

Abstract: The telephone includes a transceiver (34,36) which is attached to an antenna (40). An input key section (12) is used to program a dial memory (64) from which another subscriber can be called. A microprocessor (52) controls different operation units. A program storage unit (54,60) with at least one function key activates at least one stored control program. A monitor key (16) of a monitor unit activates a loudness level unit, which is coupled to a microphone (28). A sound signal is generated if a preset sound level is exceeded. The dial memory is activated for dialling a stored number using the sound signal. The connection to the called subscriber is terminated after a preset period of time and after a sound signal.

Rotary slide valve switch - has cylindrical cone plug in housing, with three connecting pipes, intermediates ring and flow ducts

Abstract: The rotary slide valve (1) has a cylindrical cone plug (6) pivot-mounted in a housing (2). The cone-plug (6) gas a straight trhough-hole (7) joining two flush connecting pipes and joining when the cone-plug (6) is turned-a third pipe (5) branching off the first pipe (3). All the pipes (3, 4, 5) have the same diameter. Between the rotary slide valve switch (1) and the cone plug is a concentric, multiple-duct intermediate ring (20) containing two straight through-flow ducts (24, 25) flush with the pipes and the hole (7) in the cone-plug (6). Two further through-flow ducts (26, 27) are positioned where the pipes meet at an angle with the cone-plug`s through-hole. USE/ADVANTAGE - The rotary slide valve switch combines the advantage of a single and double dividing filter.

Method and apparatus for the checking of workpieces

Abstract: A method and an apparatus for carrying out the method for the checking of double metal sheets in a metal-sheet supply device, especially a press, are proposed, in which a determination of the weight of the extracted metal sheet can take place during the transport of the sheet-metal part. Provided for this purpose is a measuring device (1), the measured values of which take into account uniform or changing speeds and therefore acceleration forces.
