Patent DE-3229066-A1 (DE)
IPC: F16L37/00
Filed: 1982-08-04
Abstract: Für das Füllen bzw. Entleeren von Behältern für Gase oder Flüssigkeiten auf Land- oder Seefahrzeugen ist es bekannt, an den Enden der miteinander zu verbindenden Leitungen Absperrarmaturen (1, 2) anzuordnen, die während des Füll- bzw. Entleerungsvorganges mit Hilfe einer lösbaren Klemmvorrichtung starr miteinander verbunden sind. Betätigt werden die Armaturen durch Stellorgane, die auf die Schwenkhebel (16, 17) einwirken. Um sicherzustellen, daß eine Trennung der beiden Leitungen erst möglich ist, nachdem beide Ab sperrarmaturen (1, 2) geschlossen worden sind, enthält die Einrichtung für die Betätigung der beiden Absperrarmaturen und für das Lösen der Klemmvorrichtung nur ein einziges Stellgerät. Die Schubstange (20) dieses Stellgerätes ist so ausgebildet, daß in der ersten Phase ihrer Arbeitsbewegung beide Armaturen (1, 2) gleichzeitig geschlossen und erst danach während der weiteren Bewegung der Schubstange (20) die Klemmvorrichtung gelöst und damit die Verbindung der beiden Armaturengehäuse (3, 4) aufgehoben wird. Durch die zwangsweise Betätigung der beiden Absperrarmaturen (1, 2) und der Klemmvorrichtung im Anschluß hieran sind Fehlbedienungen, wie sie bei Einzelsteuerungen möglich sind, ausgeschlossen. Die Einrichtung ist insgesamt kompakt ausgebildet und enthält nur wenige funktionssichere Einzelteile.

Title: Device for prestressing a pressing frame of presses for massive forming, for example extruding presses or forging presses
Inventor: STEYVERS WINFRIED
IPC: B30B15/04
Filed: 1982-08-19
Abstract: A prestressed pressing frame is composed in general of a cylinder beam, a counterbeam and pulling and pressing elements which connect the latter. The pulling elements may take the form of columns or as stacks of pulling plates and the pressing elements may take the form of pressing sleeves or pressing boxes which enclose the said plates between the cylinder beam and the counterbeam. The columns are supported via column nuts and/or the pulling plates are supported via hammer heads on the outsides of the end faces of the beams. Spacers are provided to maintain the prestressing. As all the available pressing cylinders would have to be overloaded by means of additional bolts between the cylinder beam and the counterbeam at 1.35 times operating pressure if the pulling elements were to be prestressed repeatedly, a simple prestressing device is provided here which is built into the press. Pistons slide in bores which are provided as high pressure cylinders on the outside of the end face of the counterbeam parallel to the pressing axis, which pistons are supported either on the underside of the column nuts or beneath the hammer heads. A small hydraulic high-pressure pump is used to subject the high pressure cylinders to high pressure via corresponding valves.

Patent DE-3312329-A1 (DE)
Title: Ground heat store
Inventor: SCHULTZE GEORG DR
IPC: F28D20/00
Filed: 1983-04-06
Abstract: The purpose of year round, economic heating of buildings by means of heat sources which supply thermal energy only at times and with sizeable interruptions, e.g. solar collectors, is served by a ground heat store in which both the storage medium and the thermal insulation consist of ground covered with vegetation. In order to avoid excessive thicknesses of insulating layers, the storage medium and the insulation are dried out, and renewed soaking by precipitation is prevented by covering with a water-tight layer. The introduction of the heat exchanger elements into the storage medium is performed with the aid of bores using an earth-displacing hammer, followed by laying outgoing and returning pipes for a heat transfer medium, in particular water. In order to improve the energy budget, the core of the store is surrounded by one or more shells at a relatively low temperature, which are also used at times for heating. A particularly centrally arranged buffer store having temperature stratification in an installation shaft permits a particularly simple arrangement of all assemblies. In the case of new buildings, the ground heat store can be arranged below the house and the solar collector on the roof of the house. In the case of old buildings, the ground heat store can be constructed next to the building together with a solar collector on top.

Patent DE-3318029-A1 (DE)
Title: Splashguard device for frying pans
Inventor: PRACHT GUENTHER
IPC: A47J37/10
Filed: 1983-05-18
Abstract: The previously known splashguard devices which can be placed on the rim of a frying pan are difficult to clean in the case of a fine mesh construction. In a grating-type construction, the grating must be covered by a sheet of vapour-permeable and air-permeable paper which has to be cut to fit the grating and replaced from time to time. Furthermore, when not in use, the known splashguard devices cannot be stored in a very small space. In order to eliminate these disadvantages, a multiplicity of radially arranged, elongate sheets made of heat-proof material are mounted by their one end so as to be swivellable on an axle, the sheets being placed with their longitudinal-side edge zones one below the other, whilst maintaining free gaps extending in each case over the length of the sheets.

Title: Circuit arrangement for current flow detection
Inventor: BANZER GUENTHER ING GRAD
IPC: G01R31/50
Filed: 1983-12-10
Abstract: In technical facilities, it is frequently required to detect the current flow of a flowing direct and/or alternating current. If optocouplers are used in the detection circuit, the detectable range of values of the amplitudes of the flowing current is restricted. The range of values can be slightly increased by connecting appropriate components to the optocouplers, which, as a rule, is associated with the disadvantage that the power loss increases in the detection circuit. To avoid an increased power consumption and to achieve a wide detectable range of values, at least one optocoupler in the detection circuit is arranged with self-regulating parallel current branch. The output signal of the optocoupler is converted into a digital signal which is supplied to an evaluating circuit.
