Patent SE-7513582-L (SE)
Inventor: CYPHELLY IVAN JAROSLAV
IPC: F03C1/04
Filed: 1975-12-02
Abstract: A rotary valve coupled to a radial cylinder motor sequentially provides pressure fluid to the cylinders of the motor and drains the cylinders through discharge openings in the valve casing. The rotary distributor of the valve and the valve casing have each two radial face portions directed in opposite axial directions and defining two throttling gaps connected by a chamber in the casing and respectively communicating with intake and return openings in the casing so that a pressure intermediate the intake and return pressures of a fluid prevails in the chamber and axially biases the distributor outward of the chamber while the substantially full hydraulic fluid pressure biases the distributor inward of the chamber. Recesses in the distributor alternatively connect discharge openings with the intake opening and the return opening of the valve casing. The distributor floats axially in the valve casing under the opposed biasing pressures.

Abstract: A method for the multi-stage compression of a mass in a press, especially an extrusion press containing plastic or elastic masses. The mass to be extruded is precompressed up to a preliminary pressure by the rapid advance of the pressure piston. The initial advance takes place at a high rate without the occurrence of impermissibly high temperatures of the mass or the enclosed gas. The subsequent compression to higher pressure levels takes place in a sequence of stages in each of which the rate of advance of the pressure piston is constant. The rate of advance is increased from stage to stage until a final extrusion pressure is reached. An apparatus for carrying out the method of the invention includes a hydraulic flow rate regulator which is controlled on the basis of signals that are related to the pressure measured in the hydraulic system. The pressure signals may be derived by potentiometers energized by pressure-dependent switches.

Abstract: A circuit for supplying controlled direct current power to an electric discharge vapor lamp during ignition, warm-up and normal operation. A bridge rectifier and a capacitor voltage doubler convert standard alternating current line voltage into a direct current voltage of adequate magnitude to operate the lamp. The lamp is connected in series with a semiconductor control circuit across the DC supply. The semiconductor control circuit operates as a resistive ballast whose effective resistance decreases as vapor pressure within the lamp increases during warm-up, thereby limiting lamp current to a safe value immediately after ignition while reducing the amount of power dissipated in the ballast circuit during normal operation for improved efficiency. In a second embodiment, the conductivity of the resistive ballast circuit is controlled in response to variations in both lamp voltage and lamp current to control the amount of power delivered to the lamp. In a third embodiment, controlled rectifiers in the bridge maintain a constant voltage drop across the semiconductor ballast circuit and a self-oscillating source of firing pulses is employed to start the lamp.

Abstract: This device prevents solidification of material for casting by inductively heating the feed pipe. The molten material is led from an oven or container through the pipe. The pipe is enclosed by one or more heating elements, which prevent solidification of the material. Break rings prevent the metal from setting in the pipe. The heater element may be driven at 50-200 Hz, or may also have a second frequency of 10-60 Hz which causes an inductive mixing and therefore improved warning. Alternatively, the heater may be a two- or three-phase device.
