Title: Single-button operation electronics controller
Inventor: ROTTMERHUSEN HANS HERMANN
IPC: H02P7/295
Filed: 1988-02-26
Abstract: A single-button operation electronics unit having integrated current limiting is proposed which is used especially for regulating the rotation speed of motors with commutators and in the case of which the rotation speed regulation and the limiting of the starting current, as well as the stationary armature current and the short-circuit current, are controlled via a field-effect transistor (6), there being assigned to the field-effect transistor (6) for rotation-speed regulation a potentiometer which is integrated into the rotary switch (5) and a regulating element (8) for limiting the starting current, stationary armature current and short-circuit current. The rotary switch (5) with the integrated potentiometer is designed in such a manner that all the switching processes are carried out via this rotary switch, the rotary switch (5) in this case being designed as a momentary-contact switch in the rotation direction to the left and as an on-switch in the rotation direction to the right, the integrated potentiometer also being operated at the same time in this rotation direction. <IMAGE>

Patent DE-3817283-A1 (DE)
Inventor: CREMER PETER
IPC: B21F45/04
Filed: 1988-05-20
Abstract: A device for making wire hoops for securing bottle closures, in particular of sparkling wine bottles, is characterized in that four wire feeds (1) are arranged on a support in such way that two pairs of wires (2, 2' and 3, 3') are guided to cross at an angle of 90 DEG to each other. The wires lie on the lateral flanks (4) of shaping elements (5) having shaping surfaces (6), which form with the flanks (4) an angle  alpha  = 45 DEG , and having approximately quarter-circle recesses (7) at their tips. The shaping elements (5) slide on rails (8) parallel to the directions of the wires and, during the shaping process, press with their recesses (7), against a mandrel (9) and against one another with the shaping surfaces (6), thereby leading to the formation of a four-part wire circle with double wires (10) extending from the latter. Twisting elements (11) which can be slid on to the ends of the double wires (12) are arranged in the prolongation of the double wires (10).

Title: Apparatus and process for crosslinking polymer materials with the aid of electrons
Inventor: NABLO SAM V
IPC: B29C71/04
Filed: 1988-12-29
Abstract: A description is given of a process and an apparatus for the substantially uniform crosslinking of a polymer material only to a selected depth, while the remainder of the material remains uncrosslinked or is only slightly crosslinked.

Patent DE-3907810-A1 (DE)
Title: Fastening element for heating tubes of an underfloor heating system for laying on pre-perforated rails or plates
IPC: F24D3/14
Filed: 1989-03-11
Abstract: Tube-holding clips for pressing into pre-perforated rails or plates, in which the individual holding arms are only limitedly flexible and the spreading is limited by a stop, which has the effect that when the tube is pressed in the deformation of the receiving arms is distributed evenly to both. In the event of great unilateral loading when laying curves, the deformation of the loaded arm is then, however, limited by the stop. This enables the laying of different tube dimensions in one clip.

IPC: H04N9/28
Filed: 1989-11-04
Abstract: A system for adjusting the position and size of a picture generated by deflecting a light source in response to a deflection current and displayed in a picture area larger than the picture includes sensors for sensing the picture arranged outside the picture and within the picture area. First and second differential amplifier both have an inverting and noninverting input terminal. A deflection voltage proportional to the deflection current is applied to the noninverting input terminal of the first differential amplifier and to inverting input terminal of the second differential amplifier. A first reference voltage is applied to the inverting input terminal of the first differential amplifier to produce a positive correction pulse in accordance with the difference between the deflection voltage and the first reference voltage. A second reference voltage is applied to the noninverting input terminal of the second differential amplifier to produce a negative correction pulse in accordance with the difference between the deflection voltage and the second reference voltage. A correction signal generator is responsive to the correction pulses and provides correction signals to the deflection circuit.
