IPC: F01D9/04

Granted: 1985-08-21
Abstract: A turbine to generate rotational power from a desired geothermal source from which a multi-phase pressurized and heated fluid is discharged, which fluid contains steam and particles of water, and may contain particles of solid material. The turbine includes a rotor plate (84) with a number of spaced discs (90, 92) secured to opposite sides thereof that are rotatably supported in a housing, and the housing (H) having two laterally spaced sets (90, 92a) of circumferentially disposed nozzle bodies (J) situated therein that are each adjustable to define a convergent section (50), a throat (52) and a diverging section (54). The nozzle bodies are so adjustable that streams of fluid at maximum velocity for a multi-phase fluid having particular characteristics as to heat, pressure and water droplet content discharge tangentially onto the two sets of spaced discs to flow through the spaces therebetween in spiral paths to discharge through openings in the centers thereof. The fluid as it pursues a spiral path exerts a drag on the discs, with the fluid losing kinetic energy that is transferred to the discs, rotor plate and shaft to drive them as an integral unit. No substantial lateral force is exerted on seals in the turbine as the lateral force generated by one set of discs by pressurized fluid flowing through the spaces therebetween is canceled out by a like and opposite force generated on the other set of discs by the fluid.

Abstract: For switching over from playback of the owner's announcement text to recording a message from a caller, a pause of defined length is present on the announcement tape between the first and second (or end) parts thereof. This pause is recorded and on every run of the announcement tape through the apparatus the reading, recorded for the length, undergoes comparison with the pause of the announcement tape being transported. When the two values are the same, switch over takes place. In this way, it is possible to make certain of switch over without being dependent on the tape speed, and the circuit system may be made very much less complex.

Abstract: A forced commutation defect, a simultaneous thyristor ignition, may occur for different reasons. The objective of the invention is to eliminate by a relatively simple solution the simultaneous ignition of thyristors caused by energy malfunctions, overloads, voltage variations at the input side etc. The objective is achieved, by means of a bridge connection at the inverter that transforms the direct current into an alternating current. The direct current entry point of this bridge has a main connection made up of the two controlled bridge branches connected in series having front end and rear end leads; and having at least a first half-bridge with a midpoint current outlet having a thyristor in each bridge branch; and with another, second half-bridge connected to the direct current entry connection, having two bridge branches connected in series and with a midpoint current outlet; and having an alternating current load and a control unit consisting of the control circuit for the bridge branches with at least one outlet for the control signal, and an ignition circuit for the ignition of the thyristors having at least one current entry and one current outlet, as well as a control unit containing the beat impulse generator that commands the control circuit through at least one outlet connector, that determines the frequency of the alternating current, the number of connectors corresponding to the number of phases and the phase angle being determined accordingly. For the control of the closing capacity of the bridge branches in the direction of the current flow there is provided a unit controlling the current extinction covering at a time one pair of connectors of the individual front end and rear end pole connectors of the two bridge circuits connected in series and connected at least to the first half-bridge permitting thyristor ignition, in a state of longitudinal disruption that impedes flow of current in the two controlled bridge branches connected in series, and in a state of longitudinal perfect connection of any of the bridge circuits of the control unit giving a command impeding the ignition of at least one of the thyristors of the bridge branches in disrupted state inthe direction of current flow; and, having a forced commutation extinction unit independent of the thyristor ignition, the control unit having the outlet connectors for the counter-phase extinction command that changes every half-period the electric signal level and that is synchronized with the signal of at least one outlet conector of the beat impulse generator for the independent forced commutation extinction unit per phase.

Granted: 1985-01-16
Abstract: In a freezer with a chamber, in which refrigerated surfaces tend to collect frost, with a moisture adsorbing regenerable filter in order to lower the relative humidity of the freezing chamber air and counteract forming of frost therein, the filter has had to be removed and regenerated outside the freezer. This can be avoided if the air of the freezing chamber (11) is conducted through a first flow path having a motor driven fan (17) and a filter (16) and ambient air is conducted through the fan and the filter in a second flow path for regeneration of the filter. An arrangement for the purpose is characterized in that the filter (16) is arranged in a first heat-insulated flow path, intended for freezing chamber air and containing a motor driven fan (17), that a second heat-insulated flow path, intended for ambient air, is connected to the first one before and after a part thereof containing the filter and the fan, and that valves (24, 32) are arranged for shifting of the flow paths.

Abstract: A hydraulic control device consists of a housing, a control slide valve displaceable in a bore of the housing, and a control ring. Axial displacement of the control slide valve makes it possible to connect together or to disconnect various connecting lines depending upon the position of the valve. Located in an annular chamber, formed between a section of the housing bore and the control slide valve is a control ring arranged coaxially with the valve and guided displaceably thereupon. Valve seats are spaced axially from each other both in the housing bore and on the control slide valve. The control ring comprises inner mating surfaces and outer mating surfaces cooperating with the valve seats. Provided between the two valve seats in the control slide valve is a flow channel running therein which is closed at one end depending upon the position of the control ring. The latter is held by the pressure of the flowing medium in the appropriate closed position, but the changeover may be effected independently of the pressure since no axial forces are applied to the control slide valve by the flowing medium.

Abstract: The press container of a wash press sits on a porous press plate. Because of the high press pressure of the press piston head the fabrics of the wash are partially forced into the holes of the press plate. In order to remove the pressed wash safely from the press plate, the pressed wash is raised somewhat from the press plate when the press container and press piston are simultaneously raised, first into a middle position in which the press piston head remains, while the press container is raised further. The wash loosened in this way can be safely slid laterally from the press plate.
