Title: Method and circuit arrangement for dynamic reactive-power compensation and balancing of unbalanced networks and loads having reactive-power converters
Inventor: BECK HANS-PETER DR ING
IPC: H02J3/26
Filed: 1983-03-08
Abstract: In a compensation and balancing method for m-phase systems, a short dead time of the actuating element and decoupling of the phase-current control loops are achieved. This is achieved by means of the following method steps: the instantaneous real power Pt is formed by multiplication of the mains voltages and subsequent addition, and the instantaneous reactive power Qt, which is orthogonal thereto, is formed by multiplication of the orthogonal mains voltages by the mains currents and subsequent sum formation in a measurement converter (4); the time responses of the instantaneous reactive power Qt and the instantaneous real power Pt are broken down into their spectral components by means of a moving Fourier analysis, and the Fourier coefficients of the Pt, Qt time responses are calculated and compared with nominal values; the Fourier coefficients of a control variable are determined from the control deviation, the time response of this control variable is formed in a measurement converter (9), the control variable controlling the reactive-power converter (3). <IMAGE>

Patent DE-3313881-A1 (DE)
Title: Heat storage heating appliance
Inventor: MCKENNEY JAMES L
IPC: F22B1/28
Filed: 1983-04-16
Abstract: In a heat storage heating appliance, a storage core is electrically heated. A hollow heat exchanger plate of the storage core is arranged beneath a condenser. The amount of the condensate flowing under gravity to the hollow heat exchanger plate is controlled in dependence on the pressure in the condenser. The condensate evaporates in the hollow heat exchanger plate. In order to reduce the noise generation with a wide control range, the hollow heat exchanger plate is closed at the top by a double-jacketed pipe, the outer pipe of which conducts steam and the inner pipe of which conducts condensate. Condensate reaches the hollow heat exchanger plate through openings distributed in the longitudinal direction of the inner pipe. The hollow heat exchanger plate has on the inside projections which lie in the path of falling or flowing condensate. A fine distribution of the condensate and a discharge of the storage unit thereby take place from above. <IMAGE>

Patent DE-3317150-A1 (DE)
Title: Device for varying the heat content of a liquid
Inventor: DWORAK WILHELM
IPC: F01M1/10
Filed: 1983-05-11
Abstract: The device for varying the heat content of a liquid has a gear pump (11), to the intake side of which oil under a pressure of 5 to 7 bar is admitted from the oil sump (14) of the internal combustion engine by way of a lubricating pump (12). The oil delivered by the gear pump (11) is heated by throttling at a pressure limiting valve (26) and passes into a heating device (21) with heat exchanger (20) to which the liquid gives off its heat. So that the shaft seal (52) of the gear pump is not damaged by the high pressure on the intake side, which leads to high leakages, the shaft seal is designed as a controlled gap seal with a minimal defined oil leakage, which remains constant throughout its service life. If this were not the case an excessive oil leakage would flow out by way of the gear pump, the lubrication circuit of the internal combustion engine would collapse and the latter would thus be destroyed.

Title: Multi-pole interrupter switch for a high-voltage switching installation
Inventor: LEHNER HERMANN
IPC: H01H31/28
Filed: 1983-10-10
Abstract: Provided for each pole is a moving contact set (26, 27, 28) which, on one hand, is always engaged with a fixed-position sliding contact (43, 44, 45) and, on the other hand, can be moved into and out of engagement with at least one fixed-position contact (14, 15, 16), by pivoting. The moving contact sets (26-28) are held by a common supporting body (18), which is supported such that it can rotate and consists of insulating material, and extend radially away from its rotation axis (19), parallel to one another. In order to simplify the construction and, particularly, to improve the operating reliability, the supporting body (18) has continuous recesses (20, 21, 22), which run transversely with respect to its rotation axis (19), for holding in each case one moving contact set (26-28) which, for its part, has contact fingers (29, 30) which are located opposite one another, in pairs, at a distance. Their inner ends extend into the relevant recess as far as the region of the rotation axis (19), while their outer ends extend beyond the one end of the relevant recess. Each of the sliding contacts (43, 44, 45), in contrast, extends from the other end into one of the recesses (20-22) and between the inner ends of the contact fingers (29,30). The interrupter switch is particularly suitable for metal-encapsulated high-voltage switching installations. <IMAGE>

Patent DE-3416597-A1 (DE)
Title: Machine for sealing bags
Inventor: SCHIRBEL MANFRED
IPC: B65B7/06
Filed: 1984-05-04
Abstract: A folding apparatus by means of which the bag walls are pulled taut in the upper region and by means of which gussets are inserted, is equipped with folding knives (152) which move along the bag walls inside the bag and on both sides of which suction holes (170) are situated. The suction holes (170) on each side adjoin their own suction chambers (166, 167). As the folding knives pass along the side walls of the bag, there is suction from only one side of the folding knives, whereas there is suction from both sides of the knives before and while the knives are pulled out of the bag edges. By using the folding knives (152) for suction as well, the need for a special apparatus, which takes up space, for this purpose is avoided.   <IMAGE>

Abstract: Constructed ahead of the tube-drawing installation is a frame (10) (preliminary stand) with two receiving batteries (12) each consisting of receiving tubes with a floating plug (14) and a plug bar (15). One receiving battery is at the top in coaxial arrangement with the waiting tubes (1a) in a stand-by store (4) while the other receiving battery (12) of the frame is at the bottom, coaxial to the drawing dies. While the drawing machine draws the tubes from the lower battery through the drawing dies, the tubes are moved into the upper battery from the stand-by store at the top and the ends are simultaneously pointed. On conclusion of the drawing operation, the entire frame moves a certain distance backwards, the drawing points (2) being pulled out of the pointing tool (5) and the floating plugs (14b) simultaneously being withdrawn from the drawing dies. By rotating the frame about the longitudinal axis (11), the pointed tubes are moved to a position in front of the drawing die and fed in by moving the frame forwards. A new drawing operation can begin. <IMAGE>
Patent DE-3417531-A1 (DE)
Title: Combustion-jet nozzle
Inventor: GNILKE BERND
IPC: F23D99/00
Filed: 1984-05-11
Abstract: The combustion-jet nozzle serves to improve the energy yield in energy recovery with combustion processes. This improvement is achieved in that the combustion takes place under great pressure and high temperature, and the liberated energy is converted into specific kinetic energy without components being excessively thermally loaded. The thermal loading of the components, which is not high, is achieved in that the combustion process is kept remote from the components by gas (air-oxygen) flowing into the combustion chamber from all the walls. During the conversion in the outlet hopper of thermal energy and pressure energy into specific kinetic energy, the temperature and pressure fall to magnitudes which are technically easy to handle.

Patent DE-3423257-A1 (DE)
Title: Collapsible surfboard
Inventor: SPOHR GUENTER
IPC: B63B35/79
Filed: 1984-06-23
Abstract: Surfboards are items of watersports equipment which serve as a means of propulsion by utilising wind force or waves. The problem with these items of sports equipment is their unwieldiness on account of the size. On the other hand, they cannot simply be left in the water like boats. These constant transport requirements are as a rule taken care of on the car roof. Since this involves considerable trouble and aerodynamic disadvantages, many people do not pursue the otherwise quite interesting and physically demanding type of sport. My invention is based on the idea of making the surfboards more manageable for transport so that they can be carried along in the boots of passenger cars, estate cars or on normal roof racks and even as rail or air baggage. This property is achieved by the surfboard being designed in such a way that it can be dismantled into two or more parts.
