Patent DE-3202898-A1 (DE)
Title: Drive unit for door leaves, in particular sliding leaves of doors or the like
Inventor: JAEGER LAJOS
IPC: E05F15/632
Filed: 1982-01-29
Abstract: The drive device serves preferably for sliding leaves (7) which are moved, initially with a high speed and in the end phase respectively with a low speed, both in the direction of their closed position (S) and of their open positions (O). By switching on motor capacitors (10) of different capacitance, the torque of the electric motor (9) is controlled in such a way that when the leaves are opened a large motor torque is present during the rapid opening movement. When the leaves (7) are closed, the electric motor (9) is operated in an initial and acceleration phase with a large torque but with a small torque during the further closing movement so that the closing forces of the leaves (7) are small and there is no risk of injury despite the high closing speed. <IMAGE>
Patent DE-3208389-A1 (DE)
Inventor: SCHWEFEL ERNST DIPL-PHYS
IPC: G05B19/18
Filed: 1982-03-09
Abstract: A control system for a processing machine such as an eroding machine operates to determine preferred withdrawal directions between a workpiece and a tool. In addition to the path movements necessary for the treatment process, the control system determines in advance at each point along the predetermined path a withdrawal direction oriented away from the surface being processed. This withdrawal direction runs essentially normal or perpendicular to the surface being processed on the workpiece. The amount of the desired separation between the tool and the workpiece along the withdrawal path is applied as an input to the control system in accordance with predetermined parameters of the treatment process.

Title: Method and apparatus for supporting and loading boxless sand moulds
Inventor: HOEBER HASSO DIPL ING
IPC: B22D33/06
Filed: 1982-04-02
Abstract: It is the object of the invention, in the production of castings in horizontally split boxless sand moulds on a production line, in which, to minimise the use of moulding material, the distances of the mould cavity from the edge can be kept small and the height of the sand moulds can be varied depending on the pattern, automatically to load and to provide all-round support for the sand moulds during the casting and cooling cycle. According to the invention, this is achieved by virtue of the fact that, in addition to the known laying on and removal of a loading weight, a supporting frame which automatically exerts pressure and the height of which corresponds to the minimum sand mould height, surrounds the sand mould symmetrically to the parting plane before casting, is removed after a minimum cooling time and is fed in to enclose another sand mould to be filled.
Patent DE-3213345-A1 (DE)
Inventor: WOLF GERHARD
IPC: G11C19/00
Filed: 1982-04-08
Abstract: In order to avoid unambiguous logic switching statuses in a data and control path upon transfer from one clock system of an outputting data processing system into an independent, asynchronous clock system of an accepting data processing system, and wherein a continuous data flow is to be guaranteed at the output of a buffer memory, a control signal indicating the presence of an intermediately stored data word is synchronized into a forwarding timing pattern of the accepting system via a synchronization circuit for forwarding data words from the buffer memory. A forwarding sync control signal is generated by the synchronization circuit. For controlling the in-flow into the buffer memory, a control signal dependent on the forwarding timing pattern of the accepting system is synchronized into the timing pattern of the outputting system over a further synchronization circuit. A request sync control signal is generated which respectively leads to the transfer of a data word together with a strobe signal to the buffer memory which undertakes the intermediate storage on the basis of the strobe signal. In order to guarantee a continuous data flow at the output of the buffer memory, the buffer memory has at least three, and preferably four memory sections.

Title: Method and circuit arrangement for adjusting the ejection speed of droplets in ink jet printers
Inventor: HEINZL JOACHIM PROF DR
IPC: B41J2/125
Filed: 1983-05-27
Abstract: In order to adjust the ejection speed of droplets in ink jet printers, the residual oscillations triggered in an ink channel (2) by the actuation of a piezotransducer (7) are detected and evaluated in order to form criteria (S1, S2) which adjust the control pulse voltage (U); here, a first criterion (S1) is issued when two successive residual oscillation characteristics correspond and a second criterion (S2) is issued when they do not correspond; by means of the first criterion (S1) a stepped increase takes place in each case by means of the second criterion, and (S2) the ultimate adjustment of the control pulse voltage takes place; in order to form the second criterion (S2), the pressure pulse changes which occur in the residual oscillation characteristic are evaluated directly after or directly before the detachment of the droplet; in order to measure the residual oscillation characteristic, the piezotransducer is switched as a sensor, in each case after an actuation, for the duration of a measuring period and is connected to an evaluation device (13). <IMAGE>
Patent DE-3319404-A1 (DE)
Inventor: ROESL WOLFGANG
IPC: H01H19/00
Filed: 1983-05-28
Abstract: An impulse generator includes two pairs of contacts and one indexing disk whose indexing notches are capable of moving a central resilient indexing element. The indexing element moves either toward the one or the other pair of contacts depending on the rotation of the indexing disk. Each pair of contacts is a separate contact spring assembly (15, 16; 17, 18). The indexing disk is positioned above the contact springs (15, 16; 17, 18). The indexing element is a spiral spring (10) clamped either at one or at both ends, and disposed in such a way that the centerline (14) thereof extends in relation to the indexing notches (12' and 12) so that the latter deflects the spiral spring (10) laterally toward the contact springs (15, 16; 17, 18). The spiral spring (10) is laterally deflected to actuate the respective inner contact spring (16, 17) of a contact spring assembly (15, 16; 17, 18). This results in reduced abrasive by wear of the indexing disk, and insures that a good electrical contact is reliably made.

Patent DE-3347098-A1 (DE)
Title: Process and apparatus for the separation of impurities in materials, especially in tin ore
Inventor: SCHNABEL GEORG
IPC: B03C1/005
Filed: 1983-12-27
Abstract: The tin ore was subjected to a comminution process, in which the ore was contaminated by the iron-containing dust of the wear parts of the comminuting devices used, for example the grinding bodies. A particular problem thereby arises in that the iron-containing grinding dust adheres firmly to the ore particles and thus cannot be dislodged by magnetic separating processes. The solution of the problem proposes that the contaminated ore particles are intensively stirred in a suspension, preferably in attrition cells, to then be fed to a magnetic separation process.
