Title: Method and device for digital brightness control
Inventor: OTT HANS ING GRAD
IPC: H02M5/257
Filed: 1986-04-29
Abstract: A method for digital control, especially for the brightness of lamps, by means of trigger pulses which are supplied to a phase-gating controller and are obtained from the mains frequency via a zero-crossing switch (1) with a downstream-connected phase-synchronised control loop (2) consisting of a phase comparator (3), low-pass filter (4) and voltage-controlled oscillator (5), called a phase locked loop (PLL) circuit from hereon, and of a divider (6) which is connected between the oscillator (5) and the phase comparator (3), for which purpose a clock frequency is taken from the PLL circuit at the output of the oscillator (5) and is supplied to a counter (7) which, in conjunction with a preselection counter (8) causes the trigger pulses to be emitted as a function of start signals which are obtained from the output of the zero-crossing switch (1) and are supplied to the counter (7) in a conditioned manner. It is provided according to the invention that the start signals are taken from the divider (6) at its output which is connected to the phase comparator (3). <IMAGE>

Patent DE-3624081-A1 (DE)
Title: Overvoltage protection terminal block
Inventor: VESPER WOLFGANG DIPL ING
IPC: H05K7/14
Filed: 1986-07-17
Abstract: The invention is aimed at an overvoltage protection apparatus which consists of an upper part and a lower part which are coupled via plug-in contact elements. In this case, the overvoltage protection elements are arranged in the upper part, while the lower part comprises continuous cable runs with a coupling element connected inbetween. In order to improve the protection effect and to design the apparatus in a space-saving manner, it is proposed to provide the upper part with a printed circuit board whose conductor tracks form contact elements in the lower edge region, which contact elements can be coupled into a contact receptacle, in the form of a groove, in the lower part, consisting of complementary mating contact elements which are aligned in a straight line. The overvoltage protection elements are in this case located in a board zone which is immediately adjacent to this edge region, which results in short lead elements with low inductance. The lower part is in this case provided with a housing attachment in the form of a sleeve into which the printed circuit board of the upper part can be inserted, as a housing insert, said printed circuit board being mounted vertically on a cover which closes this attachment.

Title: Device for guiding sheet-metal parts in a machine tool
Inventor: PUETZ ULRICH DR
IPC: B26D7/18
Filed: 1986-08-26
Abstract: The work table of a machine tool has a horizontally mounted receiving plate (10) which has a plurality of openings (17) and, preferably in the region of the edge, regularly distributed through holes (22). Arranged in each of the openings and of the through holes in a manner which allows them to be moved vertically relative to the work table, there are respectively a driven conveying roller (18) and a lifting pin (23). Means (11, 12) for controlling this relative motion are provided in such a way that the lifting pins and/or the conveying rollers protrude from the surface of the work table between operations. It is thus possible to remove processed parts (15) under the lifted residual skeleton (16) of the blank (14) and, if required, it is possible to feed in a new blank after the removal of the residual skeleton. <IMAGE>

Title: Protective device for a lock-mechanism housing
Inventor: HAUENSTEIN NORBERT DIPL ING
IPC: E05B17/00
Filed: 1987-03-20
Abstract: The invention relates to a protective device against the action of moisture, dirt or the like for a lock-mechanism housing (10) mounted outside the door interior on one side (13) of the vehicle door (2). There is provided a sealing strip (17) which bridges a gap present, with the vehicle door (2) closed, between the side (13) of the latter and a door striking side (7) located opposite it and fixed relative to the body and which surrounds the edge faces of the lock-mechanism housing (10). In a preferred embodiment, this sealing strip (17) is designed as a protective cap which can be slipped onto the lock-mechanism housing (10) and is matched to the contour of the latter and which completely covers the edge faces of the lock-mechanism housing (10) and only partially the side faces bearing on the vehicle door (2) and confronting the door striking side (7) fixed relative to the body. This protective device, for the formation of which parts of the vehicle body are therefore also used, is designed especially simply in terms of construction and can therefore be produced cost-effectively. Accessibility to the elements of the lock-mechanism housing is maintained at all times. <IMAGE>

Title: Reciprocating pump
Inventor: BECKER HANS ULRICH
IPC: F04B1/107
Filed: 1987-10-13
Abstract: In order to design a multiple-piston reciprocating pump to be of compact form and also handle a large head without difficulty, and be easy to adjust to the desired head, the cylinders (9) are constructed in a star configuration as essentially offset radial drillholes in a rotor (6).

Patent DE-3820761-A1 (DE)
Title: Boring appliance for pipelines
IPC: B23B41/08
Filed: 1988-06-18
Abstract: The invention is directed towards a further improvement of the boring appliance described in the main patent, in which a coupling is connected between, on the one hand, the drilling rod carrying the drilling tool and, on the other hand, the rotation, providing for the drilling feed, of a screwable housing top part belonging to the housing of the drilling appliance. One coupling half is guided in an axially movable manner on the housing top part and is thus alternatively engaged with or disengaged from a complementary coupling half held on the drilling rod. In the uncoupling position, the control member at the same time serves as a rotary handle for the drilling feed of the top housing. According to the additional patent, it is now proposed that a gear box be placed via a push-in connection onto the housing of the drilling implement, which now provides for a fixed coupling, optimally adapted to the respective operating conditions, between the drilling rod on the one hand and the top housing on the other hand, with which coupling in each case the gear input and gear output respectively are connected in a rotationally locked manner.

Title: Two-limbed plug-in core for a transformer
Inventor: WAASNER BRUNO DIPL ING
IPC: H01F27/245
Filed: 1988-07-06
Abstract: A two-limbed plug-in core exists in which two yokes 4 in each case form one yoke end surface 11 externally. In this case, it is desired for the two-limbed plug-in core in the transformer to have considerably improved electrical no-load values. This is achieved by a sheet-metal strip 12 which covers one of the yoke end surfaces 11 consisting of silicon-alloy electrical sheet metal and being free of any function relating to holding the core parts 1, 2 together. Improvements of approximately 15% or more can be achieved in the no-load current and in the no-load power. <IMAGE>

Title: Used-water toilet flushing
Inventor: HASSE HELMUTH
IPC: E03D5/00
Filed: 1988-08-23
Abstract: A water jet pump which is connected to the water-inflow pipe of the toilet flushing means takes in used water during the throughflow of fresh water and thus makes it possible for the toilet flushing to take place by a mixture of fresh water and used water. The used water taken in by the water jet pump is located in a used-water storage tank which is arranged beneath the bathtub, washbasin or shower. When the used water flows out of the bathtub, washbasin or shower, the used-water storage tank located therebeneath is filled; excess used water flows via an overflow pipe into the drainage system as waste water.

Title: Control for dental furnaces, especially microprocessor-controlled pre-heating furnaces
Inventor: KNORPP ERNST
IPC: G05D23/19
Filed: 1988-09-16
Abstract: In a control for dental furnaces, especially microprocessor-controlled pre-heating furnaces with controlled heating-up at a limited rate of increase of the temperature there is a temperature control which takes place at one or more, preferably three, programming levels with one or more temperature steps, freely or with guided programming, or on one or more temperature steps with guided programming. As a result, flexible programming options in order to implement all program flows that are presently required and are conceivable in future are created, the complicated input mode is replaced by a simple, easily operated programming structure, i.e. the dental technician can enter new programs or program amendments virtually without constant recourse to the operating instructions, and it is possible to store specific programs that are constantly re-used.
