Patent DE-2629495-A1 (DE)
Inventor: RIPPSTEIN EUGEN
IPC: H04Q3/00
Filed: 1976-06-30
Abstract: The failure of the decoupling rectifier elements in relay switching networks, such as those used in telecommunications systems, can lead to unwanted multiple connections. The method comprises three test stages, a DC test voltage (up) being applied in a first stage to any given row line (e.g. 1) and to any given column line (e.g. 1), in a second stage to a different row line (e.g. 2) and to a different column line (e.g. 2) and in a third stage (e.g. 3) again to a different row line (e.g. 3) and to a different column line (e.g. 3), and after each of these stages the current is in each case measured with the exciter coil of the relay located in the associated intersection point being interrupted. This procedure allows all the rectifier elements of a switching network of any given size to be tested at little cost in terms of testing means and also, in particular, without extensive intervention in the switching network under test. <IMAGE>

IPC: E04C1/39
Filed: 1976-10-16
Abstract: The wall for forming the boundary of plots of land or roads is easy to construct and also easy to dismantle again. It has a sound-insulating and sound-absorbing effect and is constructed from hollow bodies (2) of water-permeable material, preferably single-sized aggregate concrete, which lie one on top of the other and are at least partly open at the outer sides. The hollow bodies can be filled with sound-insulating material, and plants can be put into the open ends of the hollow bodies for covering the wall with greenery.

Title: Metallurgical coke prodn. from low-grade coal - using fusible gas-releasing inorganic additives
Inventor: MEISER ALFONS
IPC: C10B57/04
Filed: 1976-11-30
Abstract: Prodn. of metallurgical-grade lump coke from young gas-rich coal and/or old gas-lean noncaking coal comprises mixing the finely ground coal with finely divided solid inorganic additives which partially or completely melt and release gases or steam at the coking temperatue (990-1600 degrees C, pref. 1100-1500 degrees C). Using the additives, it is stated to be possible to produce high-grade coke from low-ash coals of poor caking quality, possibly due to the fact that the additives act as binders. Suitable additives are gas-rich clay, expended clay, vulcanised glass, perlite and purified sewage sludge.

Title: Heart beat regulating pulse generator - determines pulse charge quantity by integrating current flow between electrodes
Inventor: STEMPLE GUENTER
IPC: A61N1/39
Filed: 1977-01-13
Abstract: The heart beat regulation system is particularly for control of the heart beat and resuscitation in emergency situations, by means of a previously metered electrical pulse applied via electrodes. To meter the pulse, its electrical charge is determined during simultaneous measurement of the impedance between the electrodes, and controlled while taking the measured impedance into account. The charge can be determined by measuring the currents flowing through the electrodes and integrating them over the time period. The results measured are also used for impedance measurement.

Patent DE-2722064-A1 (DE)
Inventor: SITTIG ROLAND DR
IPC: H01L31/111
Filed: 1977-05-16
Abstract: The thyristor exhibits a forward-blocking PN junction (5) on the surface. This junction (5) is formed by two zones (2; 3', 3'') brought out of the interior of the thyristor by a zone (1) located on the surface, and is exposed to light for igniting the thyristor. On the surface, a particularly highly doped zone (9) is also located which is of the same type of conductivity as the zone (1) exclusively located on the surface. In this thyristor, ignition is to be achieved with very low light power without at the same time decreasing the resistance against firing with respect to a fast voltage rise. This is achieved by the fact that a first one (3', 3'') of the two zones (2; 3', 3'') brought out of the interior encloses parts of a second zone (2) brought out of the interior and the particularly highly doped zone (9) on the surface. The particularly highly doped zone (9) is electrically conductively connected to a part of the second zone (2) located outside the first zone (3', 3''). <IMAGE>

Title: Wound capacitor with metallised dielectric foils - has one metal sprayed face and other face edge free of metal deposition and foils wound in offset manner
Inventor: PETRICK PAUL
IPC: H01G4/32
Filed: 1977-06-10
Abstract: One of the face edges of the metallised dielectric foils is contacted by metal spraying. The contacted edges have an undulating course. The noncontacted face edges of the foils are straight and have an edge region (5) without conductive metallising. The foils are wound in an offset manner so that the undulating edge of each foil (1, 2, 3) lies opposite an adjacent straight foil edge, but extends over the same in the winding axis direction. The undulation of the contacted edges has a constant wavelength and a constant amplitude of at least 0.5 mm. The offset of adjacent foils is between one half and the whole of the wave amplitude. The insulating edge may be formed by local firing of the metallising. The foils may be of non-impregnated plastics.

Title: Protecting a tennis player's hand from injury and blisters - by winding a soft foam tape about the racket handle and adhesively securing it there
Inventor: WINTER HANS
IPC: A63B60/06
Filed: 1977-07-22
Abstract: Supple tape which may be wound about the handles of e.g. a tennis racket, to protect a user's hand against possible injury, is made of elastic soft foam. The tape is esp. useful when the article is used for relatively protracted lengths of time since its ability to afford a user's firm grip does not diminish with time. It is not affected by perspiration and less expensive than prior-art leather protectors. The tape is suitably 4cm. wide and 18mm. thick. When wound about the handle its free end is secured by adhesive tape. It reduces risk of formation of blisters on a user's hand.

Title: IC engine shut-down control valve - has piston biassed to close fuel supply upon oil pressure falling at max. power speed
Inventor: CUNNINGHAM PAUL B
IPC: F01M1/22
Filed: 1978-04-06
Abstract: The valve in the fuel line of an i. c. engine is normally biased to its closed position, causing engine shut-down, but prevented by an opposing oil pressure from doing so. The valve promotes engine shut-down in the event of failure in the engine oil pressure.

Title: Eye drop bottle attachment with flexible arms - which force the eyelids apart and support the bottle during use
Inventor: BOSSHOLD BARRY L
IPC: A61F9/00
Filed: 1978-04-24
Abstract: An attachment for a lightweight, squeeze-type, eye-dropper bottle includes a pair of resilient arms having frictional pads at their free ends. The arms are supported at the neck of the bottle and extend upwardly beyond the dispensing nozzle. In use the arms are flexed together and the pads are placed against the eyelids of a user. The resiliency of the arms forces the eyelids apart and allows the bottle to be squeezed to place a drop in the user's eye. When not in use the support allows the arms to be inverted so as to lie closely along the sides of the bottle.
