Abstract: ABSTRACT     This application discloses a liquid soap dispensing system including a closed soap container having a manually actuated dispensing pump carried therebeneath.  Refill of the container is by a plastic refill squeeze bottle with a neck defining an outlet opening closed by a membrane recessed therein.  One embodiment of the bottle is formed by ultra-sonically welding in the neck end, after the bottle is filled, a plug defining a cylindrical sleeve closed at the inner end thereof by a closure wall.  The neck is inserted into a well in the top of the container, and a hollow piercing member at the bottom of the well ruptures the membrane or closure member, whereupon soap may be squeezed from the bottle and through the passage through the hollow piercing member, which is constricted by septa dividing the passage into channels such that flow of liquid soap therethrough at equal pressures at both ends of the passage is substantially inhibited.  The piercing member is in sealing engagement with the plug sleeve, and annular ribs on the neck are in sealing engagement with the well side wall.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and arrangement are disclosed for operating a steam power  plant having a steam generator heated by a fluid-ized bed furnace.  The fluidized bed is provided with pressurized combustion air which permits a reduction in the bed dimensions.          Combustion gases heat feedwater passing through a series of heat exchangers in the steam generator to provide a working fluid for a steam turbine.  The steam turbine operates an electrical current generator.  The electrical current generated by the generator is the product of a purely steam generating process.          The combustion gases are also used for superheating the steam and for preheating recirculated feedwater in a heat exchanger contained within the steam generator.  The combustion gases also drive a gas turbine which is connected to a compressor, with the compressor supplying the pressurized combustion air to the fluidized bed. After vaporizing the feedwater, superheating the steam, preheating the feedwater and driving the gas turbine, the combustion gases are at such a low temperature that they can be passed directly into the atmosphere through a chimney. An increase in the thermal efficiency of the system is provided by the use of the combustion gases to preheat the feedwater and drive the gas turbine.

Title: Apparatus for monitoring phase currents and torsional  vibrations of a turbine-generator
Inventor: WOLFINGER JOHN F
IPC: H02P9/04

Granted: 1981-10-27
Abstract: Abstract of the Disclosure Apparatus is described for monitoring phase currents and torsional vibrations of a turbine-generator which are indicative of the dynamic response of the machine during operation under load.          The monitoring system disclosed includes probes which are operable to sense rotation of the main shaft of the turbine-generator and to feed the resulting signals to a vibration network. The vibration network eliminates from the signals any false components present at frequencies equal to multiples of the rate of rotation of the shaft and produces a composite vibration signal containing only true components of shaft torsional vibration. The composite vibration signal and a set of three phase current signals determined by stepping down, filtering, and amplifying the generator line currents are monitored continuously but recorded only when at least one of two signals derived from selected components of the composite vibration signal and phase current signals exceeds reference levels in an alarm system included in the monitor.

Abstract: TITLE OF THE INVENTION: Vibrating Reclaimer of Foundry Mold Material INVENTOR: Robley W. Evans ASSIGNEE: Rexnord Inc., a Wisconsin corporation ABSTRACT OF THE DISCLOSURE:           An apparatus for reclaiming material primarily used in the fabrication of foundry molds is provided in which the sand in the form of large chunks of mold is introduced into a vibrating conveyor and carried initially to a rotary hammer assembly.  The chunks are chopped into finer pieces which fall back into the conveyor and are moved into a vibrating drum assembly which causes the pieces to self-abrade into particles.  When the particles reach a predetermined size, they leave the drum through a perforated gate means and fall back into the conveyor which carries the particles to a vibrating screen.  Particles passing through the screen are then removed for further processing.

Abstract: ABSTRACT OF THE DISCLOSURE         An exhaust gas recirculation system for an internal combustion engine employs an exhaust gas recirculation control valve in a passageway connecting the engine exhaust passage to the engine intake passage downstream from the throttle valve.  The intake passage also provides a choke valve and a carburetor venturi section between the valves.  An air conduit having an air control valve therein connects the intake passage between the throttle valve and the choke valve to the intake passage downstream from the throttle valve.  Vacuum responsive actuators are provided for each of the control valves and they are operated by vacuum pressure regulated by a regulating valve, which is itself responsive to differential pressure between vacuum intensity in the intake passage upstream from said throttle valve and modified atmospheric pressure.  The modified atmospheric pressure is obtained downstream of a restriction in the air conduit.  Closing of the choke valve on a cold start of the engine causes high vacuum intake to the air conduit, reducing the exhaust gas recirculation through the exhaust gas recirculation control valve.

Abstract: 37.     METALLIZED FILM CAPACITOR AND METHOD OF MANUFACTURE           Abstract A rolled metallized film capacitor is manufactured by completely metallizing one surface of each of a pair of dielectric films, and advancing the films while laser scribing patterns of demetallized lines on the respective films which are wound together to provide a pair of capacitor plates of finite areas. As the films are advanced the laser scribing is con-trolled so that when the films are wound together, the lines on the respective films are in overlaying re-lationship on the core and peripheral windings, and are diverted to opposed marginal edge portions of the respective films on the intervening windings.  When the rolled capacitor films are terminated and connected to a power source the opposed metallized areas on the core and peripheral windings are subjected to equal poten-tials, whereas the remainder of the windings present two metallized areas between the opposed margin lines which are subjected to potential of opposite polarity to accumulate charges and function as capacitor plates.
