Patent DE-3812771-A1 (DE)
Inventor: RITTMANNSBERGER NORBERT DIPL I
IPC: B23Q11/00
Filed: 1988-04-16
Abstract: A control device for an electric hand tool such as a drill is provided with means by which a speed limitation for the motor driving the electric hand tool is effected in dependence on working variables such as the type of material to be machined and the tool diameter used. A voltage (UM) representing a maximum speed is supplied to a trigger potentiometer (9) via a digital/analog converter (8) by pressing coded keys (3,4) corresponding to selected values of the working variables. A voltage USt picked up from the slider of the trigger potentiometer acts on control electronics and can, at most, reach the preset voltage (UM). The maximum speed set is displayed by an array of LEDs (5), each LED corresponding to a combination of working variables. <IMAGE>

Title: Device for the heating of running threads
Inventor: DAMMANN PETER
IPC: D02J13/00
Filed: 1988-04-20
Abstract: When the heating surface of a device of this type curves to a relatively pronounced extent in a way which is in many cases actually desireable, a limit is established in that the cover necessary particularly for heat insulation should not be at too great a distance from the heating surface in the region of the heating-surface ends. The new device is to make it possible to fix the curvature of the heating surface according to practical aspects alone. Depending on the necessary extent of curvature, the cover is divided into two or more portions which can each be mounted and moved independently via hinges. Common actuation can take place by means of a suitable coupling connection between the individual portions. By an appropriate division of the cover, the differences in distance in the middle of the portions and at their ends can be kept within predetermined limits, irrespective of the extent of curvature.

Title: Radio data system receiver with station frequency data
Inventor: KASA KOICHI
IPC: H04H60/27
Filed: 1988-07-29
Abstract: Two transmit modes are used for station frequency (AF) data, received by a radio data system (RDS) receiver. In the first mode a group of data blocks is sequentially transmitted in a repeated manner, with each block contg. station frequency data of two network stations, transmitting an identical program.  The second mode transmits several data block groups sequentially, with the group representing station groups in the network, transmitting identical programs. The reception contains a read-out of station frequency data in two blocks only from the data obtained by demodulation of the received radio signals.  The station frequency data in the two blocks are compared for coincidence, with the data coincidence indicating that the second transmit mode has been carried out.  A non-coincidence indicates that the first mode is used for data transmission.

Patent DE-3838791-A1 (DE)
Title: Ship as sports ship of "catayacht" type
Inventor: FRANCK HANS-HEINRICH
IPC: B63B1/04
Filed: 1988-11-17
Abstract: The "catayacht" combines within itself the advantages of a catamaran with those of a sailing yacht, and furthermore offers a larger internal space than is the case with other boats of the same length. The supposed disadvantages, such as large wetted surface and relatively high weight, can be compensated by the selection and dimensioning of the rigging or motors. Once the boat comes on to the plane, there is a substantial reduction in the force required to keep up speed. An application of the described hull shape is conceivable for fast commercial ships, and likewise as special ships, for example as oil collectors for sucking up an oil carpet or other contamination from the water surface.
Patent DE-3900959-A1 (DE)
Title: Electric fence apparatus
Inventor: WEINREICH WILHELM DIPL ING
IPC: H05C1/04
Filed: 1989-01-14
Abstract: An electric fence apparatus having a pulse generator which operates in accordance with the capacitor discharge principle and contains devices (rectifier arrangement G) for energy recovery during low-loss operation of the electric fence 11, failure phenomena can occur in that the dry ground 14 forms a considerable non-reactive bias resistance RB to the non-reactive body resistance RT of the animal and, in consequence, allows only a fraction of the peak voltage of the pulse to be effective on the animal's body, like a voltage divider. In order to avoid such failure phenomena in dry weather and ground conditions, a rectifier arrangement for energy recovery is used which is of such a type that it can be switched into two different operating modes, specifically into one operating mode for energy recovery and a mode, which is switched off in both flow directions, for the pulse energy to have its complete effect on the electric fence, without any energy recovery. For this purpose, the rectifier arrangement G has added to it a mode control device which is optionally controlled manually or automatically, switches to energy recovery for n pulses, for example 3 to 5, applied to the electric fence and then to the mode which is switched off in both flow directions for 1 or 2 pulses applied to the electric fence 11. This is done in a repetitive sequence. <IMAGE>
