Patent DE-2817206-A1 (DE)
Inventor: STEMMLER HERBERT DR ING
IPC: H02H9/02
Filed: 1978-04-20
Abstract: The short-circuit current in a network is intended to be reduced within a time interval which in the worst case corresponds to half a cycle of the network frequency. In order to achieve this, an impedance-changing circuit is provided in the short-circuit current path between the network elements, which impedance-changing circuit consists of at least one inductor (L) and capacitor (C) as well as at least one converter (STR) and, in normal operation, has a low impedance for the network-frequency processes. When a short-circuit is detected, the converter is influenced in such a manner that the impedance of the circuit is increased by connecting or disconnecting the inductor (L) and/or capacitor (C). <IMAGE>

Title: High pressure tank opening sealing slab - has wedge ring deflecting externally oriented internal pressure forces
Inventor: WACLAWICZEK HERBERT VON
IPC: G21C13/073
Filed: 1979-01-08
Abstract: The sealing system is for wide-area openings in containers or tanks with high internal pressure. It uses aninwardly vaulted metal ceramic or concrete slab (1). Internal pressure forces effect towards the outside are deflected via a wedge ring (2), so as to exert mainly radial pressure on the smooth cylindrical walling (3). This is of a force such that residual active pressure constituents are absorbed by friction forces strong enough to cause a self-locking effect. This is light in weight, and compact in the sealing head area, is easily applied and removed, if required by remote control; and needs min. maintenance and testing.

Title: Folding apparatus for flexible mine ventilating duct - has alternately operated sets of radial tensioning arms forming hexagonal folds in circular duct
IPC: B31D5/04
Filed: 1979-05-17
Abstract: The method of folding vertical flexible walled ventilation ducts (1) used in mining, is carried out by a folding mechanism which forms hexagonal corrugations (4). This mechanism has upper and lower sets of three arms which project radically from a vertical telescopic column, which are raised and lowered forming the alternate folds, which a ring on top supports the unfolded circular tube section above. The 3 arms forming a set are equally spaced, so that they switch the tube into an equilateral triangle at each fold, and the combined effect of the two sets results in a hexagonal fold. The folded section rests on a support surface with a central hole with a guide bush for the telescopic tube which is lowered from below.

Title: Determination of path of ball in bowling alley - uses light barriers to compute direction of travel
Inventor: BECK ERNST ING GRAD
IPC: A63D5/04
Filed: 1980-10-17
Abstract: The path of the bowling ball is determined with the aid of a light barrier perpendicular to the centre line of the bowling track with a further two light barriers set at the same angle to the centre line, either side of the central light barrier, so that all three beams intersect at a common point on the track centre line. With this mirror images arrangement, two successive sections of the tracks result, whose length extension continually changes transverse to the track, whereby the length extent of this section is equally long respectively on a line parallel to the centre axis. Thus, a measurement can be made of which of the light barriers is interrupted first. If the bowl runs parallel to the centre axis, the sequential interruption of the light barriers is used to produce a comparative value to indicate the path of the bowl by lamps. This applies to a bowl which runs along the left or right hand side of the central axis.
Patent DE-3040160-A1 (DE)
Title: Vehicle fuel tank with two upper domes - which are connected by breather tube inside tank, leaving space between domes for spare wheel
Inventor: HUMPA PETER ING GRAD
IPC: B60K15/077
Filed: 1980-10-24
Abstract: The two domes (2,3) are connected internally by a breather tube (4). A connector tube (8) runs from a centre piece (7) of the breather tube to a point under the tank breather tube (9) which opens into the filler neck (10). When the tank is full, or is in the sloping position, fuel runs through the open ends (5,6) of the breather filling the tube with fuel. To overcome this drawback the upper end (11) of the connector tube, together with the nozzle-like end of the tank breather tube, forms a jet pump so that, when refilling the tank the fuel is sucked from the tubes. By having the breather tube located in the tank, the area between the domes can be used for a spare wheel.
