William Hazelett S. Richard Hazelett John Frederick Barry Wood ABSTRACT OF THE DISCLOSURE           Method  and system  are provided for continuously casting metal product directly from molten metal in which the molten metal is confined and solidified in a casting region defined above and below by upper and lower, cooled, endless, flexible traveling, casting belts supported by belt support systems including back-up rollers in respective upper and lower belt carriages and laterally defined by first and second traveling side dams, in which the back-up rollers and belt support systems shape and maintain the casting region for improved heat transfer and improved product uniformity and enhanced machine performance.  Contact between the casting belts and the cast product is maintained at an acceptable pressure, and the cast product is produced with substantially uniform transverse cross section.   Several methods and systems are disclosed including having one belt flexibly constrained, resulting in a movement or transverse bowing away from the casting centerline due to liquid metal head, with the opposing belt being rigidly constrained and contoured or transversely bowed towards the casting centerline in a configuration that compensates for the displacement of the flexibly constrained belt resulting in a uniform transverse cross section.  Methods and systems are disclosed including bowing the upper back-up rollers down either by manual adjustment or remote control and at the same time allowing the lower rollers to yield; intentionally rigidizing the upper and/or lower back-up rollers ox sections thereof; bowing both sets of back-up rollers in equal and opposite directions, bowing the rollers inward or outward using either manual adjustment or remote control tensioning of these rollers; bending structural frame members which are in support relationship with the rollers and thus maintaining predetermined configurations of the rollers in contact with the belts and further including down-stream tapering of the casting region while also employing any of the shape and contact control methods and systems described above.

Abstract: 7.006                    VARIABLE DISPLACEMENT GEROTOR PUMP     ABSTRACT OF THE DISCLOSURE     A gerotor pump or rotary fluid power transmission having a displacement control device for changing the volume of fluid delivered. The displacement control device operates by changing the eccentric position between the inner and outer rotors. The inlet and outlet ports of the pump are kept separate to maintain a unidirectional flow from the inlet to the outlet port across open mesh crossover zone. The closed mesh crossover zone is moved relative to the open mesh crossover zone and maintains separation between the inlet and outlet ports. As the eccentric position of the outer rotor relative to the inner rotor is changed, the volume of fluid transferred from the inlet port to the outlet port over the open mesh crossover zone is varied between a minimum and maximum amount. In one embodiment, the displacement control device is manually shifted. In another embodiment the deplacement control device is hydraulically shifted to control the displacement of the pump in response to the increasing or decreasing demand of the hydraulic system supplied by the pump.

Abstract: Abstract Improved Rotary Atomizing Process In the process of forming metal powders by rotary atomization, the atomizer disk is first coated with a stable compound of the molten metal to be poured or, if the metal to be poured is an alloy, the disk is coated with a compound of the base metal of the alloy.  The coating compound is selected on the basis of its melting point and that it can coexist with the molten metal to be poured, at the pour temperature, as indicated by phase diagrams of the materials involved.  The molten metal is poured onto the coated, spinning disk, couples with the coating, and forms a stable skull of itself over the coating.  Fine droplets of molten metal are thereafter flung from the disk, cooled and collected.

Abstract: ABSTRACT OF THE DISCLOSURE      A helical screw rotary compressor for a closed loop refrigeration system is connected in series with a condenser and an evaporator with the evaporator raised relative to the compressor and utilizes a vaporizable refrigerant miscible with a lubricating oil employed to lubricate the moving components of the screw compressor. A slide valve underlies helical screw rotors within parallel intersecting bores in the compressor housing and forms a portion of the screw compressor envelope, the rotors opening to a suction port connected to the outlet side of the evaporator.   A discharge port leads to an auxiliary chamber bearing an unload cylinder which drives the slide valve and opens to a discharge port leading to the condenser.   An oil drain passage leads from the auxiliary chamber to an oversized oil sump.  The slide valve slides in a recess within the housing.  A further drain passage leads through a drainage check valve to the sump.  Condensed refrigerant and the oil return by gravity to the oil sump.  Condensed refrigerant and the oil, upon compressor shut down, accumulate in the sump but do not reach the rotors and thus prevent clutch burnout.
