Abstract: Sound attenuating liquid-gas separation apparatus includes nested elements which are tuned to abate noise in general and at predetermined frequencies in particular in a screw compressor assembly. The apparatus includes a helical flow path defined internal of an outer shell. The shell is selectively perforated at its downstream end to allow for the egress of separate oil from it. The apparatus includes a columnar, open-ended cylindrical member internal of the outer separator shell and a discharge conduit which penetrates both the separator shell and the open end of the columnar cylindrical member disposed within the shell to create the nesting which both contributes to the oil separation proces and abates noise. By selectively dimensioning and therefore "tuning" the nested members in accordance with the characteristics of the particular compressor with which they are used, compressor assembly noise abatement at predetermined frequencies is accomplished.

The electrical connection portion includes a plurality of movable and stationary contact elements and a plurality of conductive studs assembled from the front side of an insulative block. There is a plurality of jumper plates electrically connected to selected ones of the conductive studs for establishing train line circuits.

Abstract: A flushing mechanism using a phase change fluid for flushing a toilet bowl with a reduced amount of water. The flushing mechanism includes a containment vessel adapted to fit in a standard-sized toilet tank and means within the containment vessel for forcing water out of the vessel into the bowl to be flushed. The containment vessel includes a collapsible bladder which is loaded with a phase change fluid. Water in the containment vessel is forced into the toilet bowl when the phase change fluid changes from a liquid to a vapor state. A hydraulic actuation system is also provided for actuating the flushing mechanism.

Abstract: A capillary tube assembly having a capillary tube body for connection to a refrigeration system and a tube end cap for accepting a plurality of capillary tubes each of which is identically preformed. The capillary tube assembly is adaptable to different refrigeration systems of varying capacity by utilizing a suitable number of identically preformed capillary tubes together with a suitable tube end cap. The capillary tube assembly is manufactured by preforming identically a suitable number of capillary tubes, preparing a tube end cap with the desired number of apertures and inserting therethrough the capillary tubes, securing the tube end cap to a capillary tube body and reducing the diameter of the tube body to the diameter of the refrigerant supply line of the refrigeration system to which the capillary tube assembly is to be applied.

Abstract: A diaphragm for a diaphragm-type piston characterized by an S-shaped or ogee-like profile approximating a theoretical model that is substantially free of distortion in a selected position of the piston assembly in which a convolution is formed in the annular space between the diaphragm piston and the body in which the piston operates. Being molded without a convolution, the diaphragm lends itself well to maintaining a reinforcing fabric centrally embedded within the diaphragm proper, while at the same time being substantially distortion-free in a selected position of the piston assembly.

Abstract: An operators's brake valve device for a railway locomotive that is adapted to provide brake pipe recharging in a holding position of the brake valve handle in which the release of brake cylinder pressure is cut off by a release magnet valve device that, in conjunction with an appliction magnet valve device, provides electro-pneumatic control of the train brakes. These magnet valves are controlled electrically via pneumatically piloted electrical switches that receive discrete pressure signals according to the different positions of the brake valve handle.

Abstract: A single-handle sanitary valve, of the type having valve means including a movable control disc mounted in face-to-face seating contact with a stationary valve seat, is disclosed. The valve seat disc includes temperature attentuating means operatively coupled between the hot and cold water inlet openings of the stationary valve seat disc and the hot and cold water supply conduits so that when the mixing valve is in its operative mode, a relatively large movement of the handle produces only a relatively small change in mixed water temperature, thereby achieving a greater so-called comfort zone.

A primary slip control word formation circuit for converting the multi-bit binary number word to a hexidecimal number word which is conveyed to a primary slip control table. The primary slip control table circuit conveys the hexidecimal number word to a table output selection circuit. A synchronous slip control logic circuit responsive to the axle speed and rate signals to produce a multi-bit binary word. A synchronous slip control word formation circuit for converting the multi-bit binary number word to a hexidecimal number word which is conveyed to a synchronous slip control table circuit.

Abstract: Fluid apparatus of the scroll-type are disclosed wherein radially compliant means effect relative orbital motion between first and second wrap elements such that actual moving line contact occurs between their flank surfaces, and wherein linkage means interconnect one of the wrap elements and crankshaft means such that a component of the force acting therebetween is imposed upon the wrap element in a radially outward direction in order to provide a sealing or contact force between the wrap elements. Counterweight means impose a force upon the wrap element in a radially inward direction which is substantially equal to the centrifugal force experienced thereby, whereby the contact force is made independent of the operating speed of the apparatus and self-compensating with respect to pressure conditions therein.

Abstract: An electrically actuated valve for incremental fluid flow rate control is disclosed. The valve is comprised of a valve body having an interior with a planar outlet surface against which a rectilinear valve element is slidingly operated.

The valve element has an orifice therethrough controlling flow through the outlet orifice in accordance with the position of the valve element, which is linearly actuated by a rotary stepper motor.

Abstract: A refrigeration system for temperature conditioning several comfort zones includes several VAV (variable air volume) valves each having a hot water coil conveying water whose flow rate is regulated by a PWM (pulse-width modulated) solenoid valve. Each VAV valve is connected to a supply air duct conveying cool supply air. When a zone's temperature is above a set point temperature, the opening of the VAV valve is modulated to meet the cooling demand, and the water coil is shut off. When a zone's temperature is below the set point, the VAV valve is opened to provide a predetermined constant airflow rate and the hot water coil's solenoid valve is cycled open and closed in a pulse-width modulated manner to meet the heating demand.
