Patent DE-3644087-A1 (DE)
Title: Antenna diversity method
Inventor: MAST BERND DIPL ING
IPC: H04B7/08
Filed: 1986-12-23
Abstract: The invention relates to the improvement of an antenna diversity method for receiving frequency-modulated RF signals, in which method the antenna signal voltages of two antennas are supplied to a common receiver. To be able to use a simple receiver of known design and, on the other hand, to avoid interference due to switching-over of the antennas at the receiver input, the method according to the invention is characterised by the fact that an optimisation of the ratio of the two components of the antenna signal voltages (UAA; UAB) which form a resultant antenna input voltage (UE) at the input of the receiver is effected via a control loop which is formed by the receiver (E) and a controller circuit (R), the antenna signal voltages being amplitude-modulated in opposite phases by a low-frequency alternating voltage in such a manner that a control voltage (UST) with unambiguous correlation with the attenuators coupling the two antennas is produced in the controller circuit following the receiver.
Patent DE-3702057-A1 (DE)
IPC: E04G7/30
Filed: 1987-01-24
Abstract: The system includes vertical posts with apertured disks secured thereto at intervals, coupling heads, wedge-like keys, scaffold pipes, coupling head extensions, and tank-link heads. Each coupling head has a horizontal slot receiving an apertured disk when the head is pushed into mounted position thereon, and has top and bottom key-receiving openings above and below such slot. A wedge-like key extends down through the top key-receiving opening, through a disk aperture, then through the bottom key-receiving opening, fastening the coupling head to the disk. Coupling heads for horizontal scaffold pipes have extensions insertable into the pipes. Diagonal scaffold pipes have tang-link heads, whose tank has an aperture for a pivot provided on an associated coupling head. Conventionally, the disks, coupling heads and pipes are all made of steel, the disks of 9 mm thickness and 122 mm diameter. The disclosed lighter-weight version employs disks and scaffold pipes made not of steel, but of light metal such as aluminum. The coupling heads although still of steel are differently designed, employing a smaller volume of material and thus lighter in weight. The disks are of 10 mm thickness and 124 mm diameter, producing a 33% loadability increase. Numerous other dimensional and configurational modifications of the standard elements compensate for any structural strength inferiority compared to the standard elements, but the herein disclosed lighter-weight versions thereof remain compatible with, and can be freely intermixed with, the heavier-weight standard elements.

Patent DE-3730971-A1 (DE)
Title: Wavelength-muldex arrangement
Inventor: CREMER CORNELIUS DR
IPC: G02B6/34
Filed: 1987-09-15
Abstract: A novel type of wavelength-muldex arrangement in an integrated construction is described, which consists essentially of the integrable elements of optical transmitter (3), blocking filter (5) and detector (4), which are integrated one after another onto a strip-shaped waveguide (2) on a substrate (1). The blocking filter (5) consists of an absorbing layer (51), which screens off the detector (4) against the light radiated by the transmitter (3) but, on the other hand, allows the light which is to be detected and has a wavelength ( lambda 2), which differs from the wavelength ( lambda 1) of the light from the transmitter (3), to pass largely uninfluenced to the detector (4). A diode (6) can be integrated into the absorbing layer (51), which diode (6) can serve as a monitor diode for the light radiated by the transmitter. <IMAGE>
Patent DE-3731726-A1 (DE)
Title: Method for producing laminations for stacking transformer iron cores
Inventor: MATTHES WOLFGANG DR ING
IPC: C21D9/52
Filed: 1987-09-21
Abstract: Such laminations are usually cut to a desired length from bands firstly cut to a desired width in a longitudinal dividing apparatus, and are frequently annealed in continuous annealing furnaces in order to remove mechanical stresses introduced by the cutting and stamping (punching) operations. According to the invention, the annealing is restricted only to the delimiting edges of the laminations, but at least to the longitudinal edges, with the result that metallically bare surfaces are oxidized in the immediate edge region and cutting burrs are burnt off. This annealing is performed before the deposition by means of which the laminations are deposited on stacks ready to be built. The method according to the invention is chiefly suitable for producing laminations for transformer iron cores for transformers with rated powers from approximately 50 kVA. <IMAGE>
Patent DE-3742077-A1 (DE)
Title: Suction cutter (hair cutting device)
IPC: B26B13/24
Filed: 1987-10-09
Abstract: The device only cuts while it is sucking. The scissors (4) come into action when the pipe (1) is connected to a dust suction device which has commenced operation. The scissors are fastened by means of a bracket (5) to a pipe in the milled slots (2) of which the scissors can perform their cutting action. The slots must be narrow and/or sealed off (3) in an airtight manner, to ensure that suction takes place. The length of the pipe, measured from the ends to the cutting plane, approximately matches the subsequent hair length. The hose (6) can therefore optionally be inserted into either of the two pipe ends. The opposite pipe end is guided onto the base formed by the hair and slides in a single direction across the latter with simultaneous cutting movements. This ensures that the hair is cut evenly. <IMAGE>

Patent DE-3810536-A1 (DE)
Title: Semiconductor circuit
Inventor: SUGAYAMA SHIGERU
IPC: H03K17/732
Filed: 1988-03-28
Abstract: A fraction of the current flowing through the P-type emitter region (PE) and the N-type base region (NB) of a thyristor (1) is conducted through a shunt formed by the base-emitter section of a PNP transistor (2). The base current intensity of this shunt depends on the thyristor current. This is why the base current, and thus the collector current of this PNP transistor (2), increase with increasing anode current of the thyristor (1). The current flowing through this shunt through the PNP transistor (2) is supplied via a switch (4), which is opened during the off time of the thyristor (1), to the base of an NPN transistor (3), the collector and emitter terminal of which are in each case connected to the gate terminal (6) and the cathode terminal (8) of the thyristor (1). The turn-on voltage present via the collector and emitter terminal of the NPN transistor (3) thus becomes lower than the gate-cathode voltage of the thyristor (1). The base-emitter current of the NPN transistor (3) becomes equal to the collector current of the PNP transistor (2) which, in turn, is a fraction of the anode current of the thyristor (1) conducted through the shunt of the PNP transistor (2). A fraction of the anode current of the conducting thyristor (1) is thus sufficient as control power for driving the NPN transistor (3) so that only a very low control power is needed for turning the thyristor (1) off. <IMAGE>

Title: Toe-lasting machine
Inventor: HOFF WILLI
IPC: A43D23/00
Filed: 1988-05-06
Abstract: The invention relates to a toe-lasting machine, in particular for manufacturing safety shoes with a protective cap, in particular steel cap in the toe region, in which the shoe shaft, which is drawn onto a last which is supported by a last support, bears against a toe stop and is provided with an insole on the last bottom, is, in the region of the last toe at the shaft edge, drawn (hauled over) in the direction of the last bottom by means of tongs, and the shaft edge, which then projects beyond the insole, is pushed inwards (cut in) over the insole in order to be fixed by means of adhesive applied there. To secure the protective cap during the hauling-over operation, it is essentially proposed with the invention that the toe stop is designed in such a manner that the protective cap, which is mounted on strips in the toe region, is supported below the insole and thus held firmly against displacement.

Filed: 1988-09-24
Abstract: The output voltages (Ud1, Ud2) of two D.C. choppers (7, 9, 72, 92) connected in series on the input side are to be controlled. For this purpose, the sum voltage (U SIGMA  = Ud1 + Ud2) and the error voltage (U DELTA  = Ud1 - Ud2) of the output voltages (Ud1, Ud2) of the D.C. choppers are formed as secondary controlled variables. The sum voltage (U SIGMA ) is compared to a desired value of the sum voltage (U SIGMA Soll), and fed to a sum-voltage controller (10). The error voltage (U DELTA ) is compared to a desired value and fed to an error-voltage controller (11). The output signals of the two controllers (10, 11) are added or subtracted from one another and used in this way to form the pulse duty factors (a1, a2 and a11, a12, a21, a22 or a1H, a1T, a2H, a2T) for controlling the D.C. choppers. <IMAGE>
