Patent DE-3125820-A1 (DE)
Title: Hydraulically operated drive device for shuttles
Inventor: HUNDERTMARK AXEL
IPC: D03D49/42
Filed: 1981-07-01
Abstract: The invention proposes a hydraulic shuttle-throwing device, in which the return movement of the piston is brought about by the shuttle itself, whilst at the same time the necessary shuttle-flight damping, which can be obtained by means of the dynamic pressure in the lines, is achieved thereby. In addition, there is an aid for guiding the piston rod, and therefore the weaving throwing device acting on the shuttle, into an inner end position, in which there is no contact between the shuttle and throwing device, so that the entire arrangement can be used even in a drop-box system, without the vertical movements of the shuttles in the drop box being impeded by the throwing device.
Patent DE-3127223-A1 (DE)
Title: Circuit arrangement for electronic torque cut-off
Inventor: BAUDER GERHARD DIPL ING
IPC: G05F1/66
Filed: 1981-07-10
Abstract: A circuit arrangement for electronic torque cut-off of a screwdriver, especially an impact screwdriver (hammer screwdriver) which is driven by an asynchronous induction motor. In this case, a signal which is proportional to the motor current and a signal which is proportional to the phase voltage are multiplied by one another, taking into account the phase angle, in a four-quadrant multiplier, and the product is fed to an integrator whose output voltage is compared with an independent, adjustable nominal value (required value, desired value). If the magnitude of the nominal value is exceeded, a comparator interrupts the electrical power supply to the motor, via a cut-off device. Using this arrangement, it is possible to differentiate between the reactive component and the real component and to meter precisely the energy actually emitted by the machine - even on no-load and in the event of voltage surge.
Patent DE-3129375-A1 (DE)
Title: Attachment for drilling machines
Inventor: TAAKE BERTHOLD DR
IPC: B23Q11/00
Filed: 1981-07-25
Abstract: In the attachment for a portable drilling machine for extracting the drilling dust, the dust receptacle (4) is attached at a distance on the front end of the drill-chuck housing (1) via a helical spring (23). The helical spring (23) is arranged on the drill-chuck housing (1) in a stepped profile (21) with an annular bead (22) and on the dust receptacle (4) in a cam ring (24) in such a way as to be releasable but secured against unintentional release. On its front side close to the aperture for the drill, the dust receptacle (4) has a support ring (27) made of an elastic material. The elastic support ring (27) permits effective bearing of the dust receptacle (4), even in the case of uneven bearing surfaces, e.g. masonry, and thus permits improved extraction of the accumulating drilling dust. By the arrangement of a helical spring (23), relatively large drilling depths can be produced while guaranteeing the extraction of the accumulating drilling dust. <IMAGE>

Patent DE-3139571-A1 (DE)
Title: Clamp-free vacuum filtration apparatus with automatic filter aeration
Inventor: WAGNER KONRAD
IPC: B01D29/05
Filed: 1981-10-05
Abstract: In almost all biochemistry laboratories, the problem occurs of separating small molecules (ligands, nucleotides) from macromolecules (proteins, nucleic acids). In the most sensitive molecular-specific detection method currently available for clinical use and research, radioisotope dilution, this problem occurs for example in routine operation. As a result, the liquid to be analysed is generally filtered by suction on a suitable filter (4 in Figure 1), which lies on a filter support (2 in Figure 1) and is there fixed via the stack (1 in Figure 1) by means of a mechanical clamp. The macromolecules are adsorbed to the filter; the small, generally radioactive, molecules on the other hand are washed through. The invention now dispenses with any mechanical components for fixing the chimney on the filter support. The function of the chimney attachment clamp is taken over by an annular vacuum force channel (3 in Figure 1), the low pressure of which is supplied from the same vacuum source as that for the filter support. By this means, moreover, the filter membrane lies on its mount without forces when the chimney is detached. Omitting any type of clamping attachment leads to a considerable speeding-up of the work cycle, and the automatic filter aeration leads to a series of additional functional advantages. <IMAGE>
Patent DE-3141229-A1 (DE)
Title: Revolving cylinder engine
Inventor: FROMER SHMUEL
IPC: F01C1/30
Filed: 1981-10-16
Abstract: A description is given of a revolving cylinder engine which has a housing which defines an annular space and in which two block-shaped pistons, each provided with a first end face, are arranged or guided so as to carry out mutually opposite circular movements such that, at two mutually opposite points in the housing, they reach a position of confrontational engagement which extends across the width of the annular space and in which the first end faces of the pistons face one another. At least one of the pistons has on its first side a concavity or recess, so that when the pistons are in their position of confrontational engagement, they define between them a sealed chamber. An arrangement of pins which are connected to the pistons and run in grooves provided in the housing makes it possible, in the position of engagement in one of the two abovementioned positions of revolution, for the pistons to be rotated as a unit through 180 DEG in one direction and, after separation and before being moved towards one another again to effect engagement at the other point, to be rotated individually through 180 DEG  in the opposite direction. The pistons are connected to a torque transmission device for the take-off or supply of work or power from or to the engine.

Title: Circuit arrangement for controlling systems in real-time operation, in particular telecommunications switching systems
Inventor: BECHERER CLAUSJUERGEN DIPL ING
IPC: G06F11/00
Filed: 1982-01-30
Abstract: The circuit arrangement serves to control systems, e.g. telecommunications switching systems, in real-time operation. A central computer (MP1) is relieved by transferring some of the control tasks to a computer (MP2) connected upstream. The two computers exchange data and control signals in asynchronous mode. However, in order to allow exchanged time information to be checked, both computers must have synchronised time meters. The computers (MP1, MP2) are interconnected via an asynchronous interface circuit (AIF), via which they exchange data and control signals. The real-time clocks required for time measurement during data exchange are supplied to the computers (MP1, MP2) by a timing circuit. <IMAGE>

Title: Deflection unit for television picture tubes
Inventor: BOHN JOSEF DIPL ING
IPC: H04N3/233
Filed: 1982-08-16
Abstract: The correction of raster distortion consumes considerable time in the manufacture of television display units. The present invention is intended to create a deflection unit which requires little effort for raster correction. Starting with the idea that a deflection unit, windings of which carry the deflection currents are located in grooves (2), generates reproducible magnetic fields, and when such a coil former (1) is used, a carrier plate (12) for permanent magnets (8, 9, 107, 11) is attached to this former in accordance with the present invention, which magnets are immovably attached before the coil former (1) is installed. The entire deflection unit is therefore completed before the installation. After that, only some corrections have to be carried out which are due to a deviation from the axis of the electron beam system and of the glass neck of the respective picture tube. The main field of application of the invention are television display units. <IMAGE>
Patent DE-3233860-A1 (DE)
Title: Device for holding parallel the slide on hydraulic punching presses
IPC: B21D28/20
Filed: 1982-09-11
Abstract: To hold the slide parallel during its downward movement, piston/cylinder arrangements (supporting cylinders) are provided, which are arranged between the press column (1) and the slide (5), and whose cylinder chambers are connected to a hydraulic control circuit which controls the pressure of the pressure medium in the individual cylinder chambers in such a way that, with the onset of tilting of the slide (5), the counterpressure of the supporting cylinders (10 to 13) is increased at the corresponding points on the slide (5) so as to counteract a crooked position. In order to be able to detect tiltings of the slide (5) in both coordinate directions with respect to a plane running perpendicular to the direction of movement of the slide, four supporting cylinders (10 to 13), which can be controlled independently of one another, are provided, these engaging on the four corners of an essentially rectangular slide (5). The supporting cylinders (10 to 13) are controlled with the aid of a multiple piston/cylinder arrangement (15) and a pressure-control apparatus (31), such as, for example, a throttle, which can be set to a constant pressure value for a preset flow rate. This device also serves for suppressing the cutting stroke at the moment of break. <IMAGE>
