Patent DE-2631824-A1 (DE)
Inventor: HEUCKEROTH RAINER ING GRAD
IPC: H04B3/56
Filed: 1976-07-15
Abstract: In order to enable the implementation of less high-voltage resistant and therefore broader-band components in the arrangement, an air-core, low-capacitance inductor (L) is inserted between the outer and inner conductors of the coaxial cable. Compared with the impedance of the coaxial cable, the impedance of this inductor (L) is high for the data transmission band and low for the frequency of the high-voltage installation. <IMAGE>

Title: Displacement brake force regulator for multi-axle vehicle - has spring constant varied by static axle load distribution and displaceable piston to vary brake force ratio
Inventor: VOIGT DIETER
IPC: B60T8/30
Filed: 1976-08-11
Abstract: The displacement type brake force regulator is used for multi axle motor vehicles. This displacement regulator generates parabolic force distribution approaching the ideal curve of the braking force loss. The brake force ratio can be varied by the additional effects of a variable force acting on the piston separating the circuits by pressure or by pressure and load variation. The static axle load distribution of the vehicle regulates the effective spring constant of the displacing spring according to the demand. The regulator forms a single unit with a double circuit main brake cylinder.

Title: Hinged ski brake arm - has enclosed movable steel ball located on side of ski near binding
Inventor: CADLINI ALBERTO
IPC: A63C7/10
Filed: 1976-10-22
Abstract: A hinged brake arm (1) has the function of stopping a ski that becomes detached from the ski boot. The fixing pivot (8) is located in the side face of the ski, near the ski binding. Under normal conditions, the ski boot holds the swivel arm (1) parallel with the ski so that no obstruction occurs. When the ski is loose, an enclosed steel ball inside the hollow arm (1) ensures that the arm pivots in such a way that the end of the arm digs into the snow. Both ends of the brake arm have cavities (2) which improve the braking action on hard snow or ice.

Title: Choke for HF use - is formed by cutting spiral groove with required pitch in metallised core
Inventor: SCHMELLER ANTON ING GRAD
IPC: H01F17/04
Filed: 1977-01-15
Abstract: The choke comprises a core of ceramic, ferrite, insulated and compressed iron powder, or similar material which is covered with a metallised layer. A groove is then cut into the metallising, and also the core if necessary, in the form of a spiral whose pitch gives the required number of turns. This operation is similar to that used for the manufacture of resistors. The technique reduces the manufacturing time and the number of components required for the assembly. It also permits the more accurate tolerancing of chokes, as the value of inductance can be measured before completing manufacture, and the number of turns or depth of groove adjusted to give the required value.

Title: Power regulator for RF communications transmitter - uses directional coupler to automatically reduce transmitter power as mismatch to load increases
Inventor: HUPFER KONRAD ING GRAD
IPC: H04B1/04
Filed: 1977-03-11
Abstract: The power regulator, for an RF communications transmitter, automatically reduces the transmitter's power as the degree of mismatch to the antenna increases. Overload of the individual amplifier stages is thus prevented. A directional coupler (3) is located between the load (4) and the output of the transmitter's amplifier (2). The coupler produces two output voltages: one proportional to the forward power (Uv) and the second proportional to the reflected power (Ur). The two outputs (5, 6 and 7, 8) are combined and used to regulate the output power. The combining operation may be simple addition.
Patent DE-2712584-A1 (DE)
Title: Filter for swimming baths and hot water systems - with concentric filter elements surrounding heating annulus
IPC: B01D35/18
Filed: 1977-03-22
Abstract: The filter consists of a cylindrical casing with a central bottom inlet. Two cylindrical concentric grids form between them an annular space. The inside of the inner and the outside of the outer grid receive a corrugated filter element through which the water flows radially. The clean water output is at the bottom of the annular space which houses a tubular heating coil. Concentric guide plates on the sides of the filter elements towards the outlet are sealed at the bottom so that the water is forced to ascend and pass through slots at the top into the annular heating space which it traverses in the downward direction. The filter is compact and combines filtering action with an energy-saving heating of the circulating water.

IPC: B29C48/11
Filed: 1977-07-30
Abstract: In the parent patent a stretched hollow non-circular extrusion is produced with corrugated webs by extruding thermoplastic material with a number of hollow spaces along its length which are divided by crosswebs, the plant uses a suitable nozzle and expands the polymer while hot by internal gas pressure, the hollow profile passes through a space whose width is proportional to the required degree of stretching and in which it is cooled when the desired cross-section is reached. In this addn., the lengths between the crosswebs are alternately increased and decreased in thickness by corresponding reduction and increase respectively in flow resistance within the nozzle tool. These flow resistances alternate however also on the opposite sides of each length. System produces differences in wall thickness as required.

Title: Container for storage of oil on the sea floor - with tapered ends to reduce stress in diagonal flexible diaphragm
Inventor: ALF EKKEHARD DIPL ING DR ING
IPC: B65D88/78
Filed: 1977-08-05
Abstract: Container for storage of oil or similar fluids on the sea floor is in the shape of an extended column with square section, each end of which is tapered to a wedge shape by two triangular plates meeting on a diagonal to the square section. The container is divided diagonally by an oil-and water-resistant flexible diaphragm, which is flat or only slightly non-planar when made, and narrows gradually towards the two ends. Used permanent submersion near oil wells to receive oil and allow discharge into tankers as required. The geometrical construction of the container ends and the diagonal sepn. into oil and water compartments reduce biaxial stresses in the diaphragm, as it moves from the oil-full to water-full position, to a min. The flat configuration of the diaphragm simplifies mfr. and eliminates wrinkling or folding when in the intermediates position.

Title: High-pressure stop valve - has truncated-cone sealing faces coated with high-grade non-corroding steel
Inventor: OERTEL RUDOLF DIPL ING
IPC: F16K5/20
Filed: 1978-10-02
Abstract: The stop valve is for a pipe handling a high-pressure medium, particularly oil or natural gas. The seal is pressed into place by the medium, and the sealing member is an annular piston, radially adjustable to leave a clearance between it and a guide chamber. Its movement is effected by a seat sealing ring and an actuating piston. Both pistons are regulated by a control valve and when opening a rotary plug at right angles to the flow direction sealing faces operate concentric to the plug and to the flow direction. On shutting by turning the plug through 90 deg., sealing faces of solid cross-section come into use. The sealing faces are truncated-cones at right angles and concentric to the flow directions (x-x), and are formed by a relatively thin but non-corroding layer of high-grade steel on a conventional base material.
