Title: Motor vehicle lamp failure control signal transmitter - has astable multivibrator with output connected via operational switch to signal lamps
Inventor: HOFER WALTER
IPC: B60Q11/00
Filed: 1978-11-30
Abstract: The signal transmitter is designed for a motor driven vehicle. It has an astable multi-vibrator, to whose output are connected several signal lamps via an operation switch. A measuring resistance is included in the signal-lamp-current circuit and is connected to a threshold switch, which is set in a reverse state by the in synch. signal-lamps, with a decrease in the applied potential across the measuring resistance during one clock interval of the multivibrator. When one of the signal lamps malfunctions, the threshold is no longer set into a reverse state. A part (25) of the RC - gate (41) is connected up to the input (B) of the threshold switch (20). The other part (42, 43) lies on the output - on the lamp-circuit side - of the signal transmitter. The capacitor (42) is then charged up and discharged in synch. with the signal transmitter. In section (25), at the input of the threshold switch (20), the voltage, which appears is inversely rectified - w.r.t. the decreasing voltage across the measuring resistance (11).

Title: Degassing plate for grinding wheels - made of solid fluorocarbon with venting grooves on surface
Inventor: JAEGER HANS
IPC: F27D5/00
Filed: 1979-07-21
Abstract: Degassing plates for use in the manufacture of high-duty grinding wheels are made of solid fluorocarbon of the FEP type instead of the fluorocarbon coated metal discs. The new degassing plate was found to be usable many more times than the conventional discs. In the case of cup-type grinding wheels, the degassing plate is shaped with a raised centre to suit. Grooves can be arranged on the surface to vent the gases to the outside. The repeated use of such degassing plates results in considerable savings.

Title: Soil improvement implement for growing plants - has double blade to lift and crack soil and break up layer below roots
Inventor: WEICHEL ERNST
IPC: A01B11/00
Filed: 1979-09-13
Abstract: The method of treating the soil in which plants (103) are already growing, so as to improve their growth, uses an implement drawn behind a tractor, with two blades (108,109) one above the other. These are pulled through the earth below the level of the roots, so as to break up a layer (102) below that level (106) into small fragments. At the same time, the blades lift the upper layer so that vertical cracks are formed across. The effect is to aerate and loosen the soil to improve growth. The action can be improved by a blade which precedes the double blade so as to form a starting cut and begin the lifting action. The double blades can be rotated or oscillated by a suitable drive on the framework to which the tools are attached. Auxiliary attachments can be added, including a fertiliser distributor which discharges behind the double blades.

Title: Glass fibre reinforced press mat - made by continuous rolling from polyester mat, casting resin and glass fibre mat
Inventor: KRAUTWALD HERBERT
IPC: B29C70/50
Filed: 1980-03-05
Abstract: Glass fibre reinforced mats, e.g for the compression moulding of parts e.g cubicles for road traffic control installations, are produced continuously in the form of a long web. A glass fibre mat, impregnated with resin, or resin impregnated roving is rolled together with a polyester mat and casting resin. Two polyethylene foils enclose this band at the bottom and top before the assembly is pressed together to a press mat. Prior to ultimate use, the two polyethylene foils are stripped off. This saves having to cover the usual cubicles made of glass fibre reinforced thermosets, with polyester mats to prevent glass fibre washout by exposure to sunshine.

Patent DE-3020515-A1 (DE)
Title: Coupling piece between rectangular waveguide and dipole wave conductor - has dielectrically loaded transition stages in relatively small steps of similar length
Inventor: EHRLINGER WOLFGANG DIPL ING
IPC: H01P5/08
Filed: 1980-05-30
Abstract: To minimise reflection losses the transitions between a wave guide (1) of height (b) in the E-plane, and the slit conductor with a slit width (W4) between the metallised areas (3), step charges should be as gradual as possible without requiring too large a length. This is achieved by the substrate (2) being completely free from any metallisation over a length (L2), with a first step of the length (L2) reducing the metal-free portion to a smaller width (W2), and a further stage having a metal-free width still narrower (W3), until finally reducing to the dipole conduction strip width (W4), which may be only a fraction of a millimeter in the medium Ghz range. The effectiveness of these transitions is due to the di-electric loading by the substrate material within the otherwise empty wave guide. In a specific case, the impedance of the wave guide was 1700 Ohm reduced by the coupling piece to a strip conductor impedance of only 70 Ohm. This substantial transformation was attained at an attenuation of only 02 db.
