Title: Device for the transverse cutting of a moving film web
Inventor: HAX WOLFGANG
IPC: B65H19/26
Filed: 1981-04-28
Abstract: The invention relates to a device for the transverse cutting of a moving film web in the course of winding the film web to form a film roll. The principle construction includes a transverse cutting knife and a transverse cutting knife holder. The transverse cutting knife can be moved towards the film web to be cut and synchronously with the film web. For this purpose, the transverse cutting knife holder is rotationally driven about a knife-holder shaft. The transverse cutting knife possesses a toothed blade whose teeth grip into the film web at the commencement of the cutting operation. The transverse cutting knife holder is traction-driven by the film web itself, via the transverse cutting knife. As a consequence, complicated measures, from the point of view of control or of the drive, are not required for the synchronous drive described above. <IMAGE>

Title: Fuel injection nozzle for injection internal combustion engines
Inventor: KLINGER HANS-JOACHIM DIPL ING
IPC: F02M61/18
Filed: 1981-05-05
Abstract: Fuel injection nozzle with a nozzle needle, capable of lifting inwards from the needle seat, the stem of which needle has a relief duct, by way of which, during the opening and closing process, a temporary connection is made between the pressure duct, to which fuel is admitted, and a leakage duct, which opens in the bore of the valve body accommodating the nozzle needle. In the opening process, fuel can flow out by way of this relief duct, so that the opening process is slowed and the combustion process is softer. In the closing process, on the other hand, fuel is displaced by way of the relief duct, so that the closing process is accelerated and any after-trickling of the fuel injection nozzle is prevented. In addition to an especially simple construction, in which the nozzle needle itself acts as control element, this design has a relatively small dead volume.

Title: Circuit arrangement for the stabilisation of the thrust-forming forces of synchronous machines
IPC: H02P25/024
Filed: 1981-08-01
Abstract: The patent application filed under the title "Circuit arrangement for the stabilisation of the thrust-forming forces of synchronous machines" relates to the frequency-variable operation of linear or rotating synchronous machines. A synchronous machine fed with frequency-variable voltage shows a weakly damped or unstable operating behaviour (pulling out of step) if control measures are not taken. For stabilisation it is necessary for the frequency and the phase angle of the feeding currents to follow the movement of the reaction part. In this connection, it is of particular importance to obtain information about the spatial position of the reaction part with reference to the positionally fixed primary part (pole position). The method described above serves to calculate this information by pulse convolution of the quantities current and voltage measurable at the machine terminals and from this to derive a correcting quantity for influencing the currents which flow in the primary parts.

Date Mar. 31, 1983.In a method for reducing the start-up and stabilization period losses, for increasing the usable power and to improve the controllability of a thermal power plant, there are integrated into the power plant's steam cycle pressurized heat storage reservoirs which are charged by feeding them with excess heat produced in the said power plant as, for example, during the start-up and load stabilizing periods or during periods of reduced electrical power production and, when there is an increased demand for heat, the said heat storage reservoirs are discharged by the release of stored heat into the water-steam cycle. Control deviations in the electrical power while the power plant is in full operation are counterbalanced by changes in the charging and discharging streams of the pressurized heat storage reservoirs. In the apparatus for carrying out this method, pressurized heat storage reservoirs are connected, on the water-side, to the condensate system and, on the steam side, to the medium pressure of intermediate superheater network of the steam cycle or also to the power plant's medium pressure or low pressure turbine extraction points.
