Abstract: ABSTRACT OF THE DISCLOSURE            A cyclone-type separator for separating water from a steam/water mixture.  The separator is of the type of an upright, generally cylindric vessel whose upper portion defines a steam zone, the lower portion defining a water zone.  A separation zone into which the steam/water mixture is normally introduced in tangential fashion, is located between the two former zones.  A conduit communicates the interior of the separator at the steam zone with the interior of same slightly above the top level of the water zone, to return a film of water formed on the inside wall of the separator and rising towards the top thereof.  Thus, the film of water is returned through said conduit back to the proximity of the water zone top level to increase the separation efficiency of the device.

Abstract: ABSTRACT      A magnetron energizing circuit preferably uses two transformers of the high leakage reactance type having isolated secondaries with an end terminal of each secondary connection to a common point which is at ground potential. The secondaries are connected to series condensers in two loops which provide leading current flowing in the secondaries at all times while both are connected in the circuit to produce saturation in the respective cores of the secondaries whereby to achieve substantially constant current and good regulation for variations in the primary voltage.  A single magnetron is served by the circuit and variations in the loading of the magnetron are also compensated for by virtue of the substantially constant current circuit.      A modified form is described which uses a single transformer having two isolated secondaries.  The secondaries are connected in opposite phase with respect to the respective capacitors which they serve to charge to obtain a full wave doubler operation when the transformers are both in circuit but with low peak current.  The combined secondaries and condensers are connected through a rectifier or rectifiers to a magnetron used for heating purposes, the magnetron participating in the overall operation of the circuit and being of the continuous wave pulsed type so as to achieve heating in cooking ovens or the like.      Disconnecting one of the transformers from the circuit converts the circuit into a lower power, but efficient half wave voltage doubler circuit.      Isolating rectifiers prevent circulating currents.

Abstract: ABSTRACT OF THE DISCLOSURE       A hydraulic valve is disclosed which has a gasket sealing against and, to a limited extent axially movable on, a movable valve member. The valve member has a radial shoulder sealing surface which is spaced from a matching, larger diameter concentric radial shoulder sealing surface  of the body of the valve. The sealing surfaces can be aligned with each other by an axial movement of the valve element, with a radial spacing between  them providing a fluid passageway. The gasket has an angular cross-section, with the apex being toward where the sealing surface of the valve element adjoins the valve element surface over which the gasket extends outward from the axis of the valve element. The angular relationship between the aligned sealing surfaces and the sealing portion of the gasket is such that when the gasket is moved toward the sealing surface of the body by the valve element, the outer lip of the gasket sealing portion first contacts the surface, thus significantly blocking fluid flow. This causes the gasket sealing portion to be pushed by the fluid pressure itself so that the gasket rotates about its cross-sectional torsional axis to press the sealing portion flat against the aligned sealing surfaces and over the fluid passageway to block its flow.          Various relative configurations of the gasket and sealing surfaces are disclosed.  Also disclosed are combinations of such arrangements for forming multiple-function valves.     1.12.1978 Sb/VRU/lf

Abstract: 19.              TRIMBLE, L.E. 1-9 FORMATION OF CYANATE COMPOUNDS       Abstract of the Disclosure This invention relates to the use of a reaction mixture of carbon monoxide, an oxide of nitrogen such as nitric oxide, and a source of hydrogen when passed over a hydrogenation catalyst for producing cyanate compounds, e.g., ammonium cyanate and isocyanic acid.  The reaction conditions chosen determine the relative amounts of the various cyanate compounds to be formed.  When the formation of ammonium cyanate is desired, the addition of ammonia to the reaction mixture reduces the amount of nitric oxide reactant necessary, while enhancing the efficiency of ammonium cyanate production.  When a palladium or iridium catalyst is used, the production of isocyanic acid is favored.  The reaction is conducted under relatively low pressure conditions, e.g., within a range of from 0.1 to 10 atmospheres, e.g., at 1 atmosphere.

Abstract: ROTARY FLUID PRESSURE DEVICE                     Abstract of Disclosure A rotary fluid pressure device is described as com-prising a housing having fluidinlet and outlet openings and in the housing is a gerotor device having an external stator having internal teeth and a rotor within the stator having external teeth, one less in number than those on the stator.  The rotor is eccentrically mounted with respect to the stator so that upon rotation of the rotor, the sealing engagement between the external and internal teeth forms expanding cells on one side of the line of eccentricity and forms contracting cells on the other side of the line.  A drive shaft concentric with the rotor has a hollow end within the housing and a solid drive end out-side of the housing.  A wobble stick drivingly connects the rotor and the shaft and the wobble stick has a pivot point at its in-ner end connected by a rigid pivot pin with a central recess in the housing axially of the shaft which eliminates axial movement between the drive shaft and the rotor which would otherwise be caused by an uneven end formed by wear on the wobble stick.  A manifold, fixed in the housing, provides a double balance pad diametricaliy opposite each of an inlet passage for conducting inlet fluid to each of the cells between the stator and rotor.          Twelve shallow slots are hobbed  over six angled holes conduct-ing fluid to the expanding and contracting cells and over six radial holes leading to the balance pads, giving the required accuracy.  A novel seal and thrust bearing structure, where the drive shaft exits from the housing, results in good concentri-city of the seal carrier and a thrust bearing between the seal carrier and the adjacent end of the housing provides with a flow pumped by the bearing during rotation of the device, which results in a lower temperature on the seal and bearing.

Means for superheating and removing the vaporized gaseous mixture from the vessel are provided.  The method of vaporization comprises withdrawing the mixture as a liquid from a supply source and passing it into the vessel to form a liquid phase.  The level of the liquid phase is maintained above a predetermined level and sufficient heat is supplied to vaporize a portion of the liquid phase at a temperature greater than the dew point temperature cor-responding to vapor having substantially the same composi-tion as the known composition of the liquefied gas mixture from the supply source at known pressure, thereby forming a gaseous mixture.

Abstract: (Case No. 6996) ABSTRACT OF THE DISCLOSURE    A vital circuit network, equivalent to a two element, alternating current track relay used as a synchronous detector, has a first input transformer directly coupled across the local track circuit source and a second input transformer coupled across the track rails through a band pass filter tuned to the track circuit frequency.  The transformers are designed to normally produce secondary output signals of the same range, which are connected into a series circuit network including a second band pass filter, a varistor, a full-wave rectifier, and a protective fuse, with a biased track relay connected across the rectifier D. C. output. From the two voltage signals in the series network, the varistor produces a product current signal which is rectified to provide an output sufficient to pick up the track relay only when both input signals are present, are of the track circuit frequency, and are within a predetermined phase relationship.  The varistor circuit network has a sharp rejection of input signals outside the predetermined phase relationship or of a nonselected frequency.
