Patent DE-3005434-A1 (DE)
Title: PCB etched inductance module with spiral form inductance - positioned on top squared board section with trapezoidal taper lower part to drop into PCB slot for main board solder connection
Inventor: BERTL GERD
IPC: H05K3/36
Filed: 1980-02-14
Abstract: An inductance on a substrate module has a trapezoidal base to simplify installation and connection to printed circuit boards. The inductance is a copper spiral etched so that it fills the top squared part of the substrate. A central hole in this part of the substrate is used to connect one end of the inductance through to a copper connecting track on the reverse side of the substrate. The outer end of the spiral is connected directly, and preserved so during etching, to a copper strip which forms the other connection to the inductance. Both copper strips extend down from the squared part of the substrate to the trapezoidal part so that this part enables the inductance to sit above the board and the terminal strips from the inductance to extend below the board for connection to the PCB track using soldering techniques. A meandering form of inductance track may be used on the substrate instead of the spiral form. The dielectric constant of the substrate is greater than 100 and its dimensions are 0.5 to 1.5 mm thick by 4 to 8 wide and 5 to 15mm high.

Title: Faired pedal cycle with luggage compartment
IPC: B62K17/00
Filed: 1981-02-12
Abstract: Two-wheeled pedal cycle with a fairing which covers the wheels and the drive in the manner shown in the drawing, but, at the same time, also runs in front of and underneath the pedal cranks as a splash protection (1). In addition, a luggage compartment (2), provided with a closable flap (3), is formed by this fairing above and next to the rear wheel. The fairing can be constructed from plastic (glass-fibre reinforced plastic or the like) with a rigid foam core in such a manner that it serves as a load-bearing chassis and a conventional frame is thus unnecessary. With this fairing, optimum protection of the driver and his clothing against whirled-up dirt, spray and oil is ensured; furthermore, the risk of injury on driving and running elements is averted. Accessories, such as a pump, tool, locking chain etc. can be stored safe from theft in the luggage compartment, and pieces of luggage, shopping etc. can be transported in a safe and secure manner. Shopping in various shops is considerably facilitated since the purchases can in each case be locked up in the parked bicycle. A heat-insulating sandwich construction of the luggage compartment walls allows transportation and storage over several hours. <IMAGE>

Title: Mounted snow plough for a supporting vehicle
Inventor: BEILHACK WILHELM DIPL KFM
IPC: E01H5/06
Filed: 1981-03-09
Abstract: The invention contains a mounted snow plough for a supporting vehicle with a plough blade, which is connected to a supporting frame by means of a rubber-elastic hinge strip, which is fixedly clamped by both longitudinal edges in the plough blade on one side and in the mount frame on the other. The longitudinal edge, which is assigned to the mount frame, of the rubber-elastic hinge strip has a downwardly projecting bead which prevents metal parts of the plough blade and the mount frame from colliding with one another when the lower plough blade edge strikes an obstruction, causing the plough blade to pivot about the pivot axis. In this manner, the plough blade can operate with a low level of noise to a substantial extent, both in the operating position and in the extended position of the plough blade, and the rubber-elastic hinge strip ensures that the pivot bearing is of very simple design, and the said hinge strip also fulfils the function of a limiting stop in addition to its principle function.

Title: Noise pulse simulator
Inventor: SATO YOSHIRO
IPC: G01R29/26
Filed: 1981-03-12
Abstract: The noise signal simulator according to the invention comprises a reflection absorption circuit which is disposed between a high-frequency noise pulse generator based on the charged delay line principle and a capacitor serving as a DC block, the latter leading to the mains connection of the device under test. The reflection absorption circuit comprises a parallel resistor and a series resistor. The resistance values of these resistors are defined in such a way that the impedance, seen from the input side of the reflection absorption circuit, is the same as the output impedance of the generator and that the impedance, seen from the output side of the reflection absorption circuit, essentially corresponds to a pre-defined standard impedance. Furthermore, an earthed printed circuit board, by means of which the stray capacitance can be set before the noise signal simulator is used, is movably disposed in the vicinity of the series resistor and the capacitor serving as a DC block. <IMAGE>
