Title: Junction box for electrical installation
Inventor: SCHNEIDER WOLFGANG
IPC: H02G3/18
Filed: 1986-11-08
Abstract: The subject matter of the application relates to a junction box for electrical installation having a base on which two or more terminal blocks are arranged and having a cover shell which can be fitted on and covers the base including the terminal blocks and in whose wall prepared cable (line, lead) entries are incorporated. Such a junction box is intended to be improved in that wiring from the side is made possible with the covering shell removed and a particularly flat structural shape can be maintained. For this purpose, the base of the box is an essentially flat base plate on whose edge the terminal blocks are arranged with their cable entry sides located towards the interior and above the plane of the base plate. Furthermore, the cable entries in the covering shell are open towards the base plate and are closed automatically when the covering shell is fitted on to the base plate. <IMAGE>
Patent DE-3640806-A1 (DE)
Title: Switched-mode power supply for DC loads, especially motors
Inventor: BECKER KLAUS DIPL ING
IPC: H02M3/155
Filed: 1986-11-28
Abstract: A circuit arrangement is described for the regulated supply of DC loads and, in particular, DC motors from a switched-mode power supply. The switched-mode power supply (2), which has a control input for power regulation, charges an energy-storage capacitor (C17) for the load (M). A current sensing resistor (R25) supplies a voltage which is proportional to the current consumption and influences the power emitted from the switched-mode power supply (2), via a semiconductor switch (V13). If the load is a motor (M) it is possible for the supply voltage to be increased with increase in mechanical load on the motor and thus an increase in motor current, so that the rotation speed of the motor can be kept constant over a wide range. When the load (M) is disconnected, the voltage which is then present on the energy-storage capacitor (C17) is kept at a relatively high value by means of a zener diode (D2) so that, for example, reliable starting of a motor (M), as the load, is ensured. <IMAGE>

Title: Screw-feeding device for screwdriving machines
Inventor: DRESPA GERD
IPC: E04D15/04
Filed: 1987-11-17
Abstract: The screw-feeding device is intended as an accessory for a drilling machine suitable for screwing, or screwdriving machines (impact screwdrivers). The device functions in such a way that the screw slides out of a magazine into an inserting mechanism and from there is conveyed via a channel into a guide tube. In this position, the screw is pushed in front of the screwdriver by pressing the device onto the object. The slide or ball springs situated in the guide tube prevent the screw from sliding out and at the same time centre it. By continued pressing-on, the screw is conveyed further forwards to the outlet opening and then screwed into the object. A spring ensures that the parts which are pressed together during screwing are returned to their starting position.
