Title: Hopper system
Inventor: ALACK CHARLES S
IPC: B65D88/72
Filed: 1988-10-11
Granted: 1991-09-24
Abstract: Abstract of the Disclosure A hopper system comprising a hopper having a side wall sloping downwardly and radially inwardly from the inlet at the top of the hopper to the outlet at the bottom of the hopper.  Secured to the inside of the hopper is a membrane having a shape generally conforming to the inside of the hopper and closely overlying the conical side wall of the hopper.  The membrane is permeable to air but gen-erally impermeable to fluent material in the hopper and has a plurality of pockets for receiving stay bars.  The upper and lower cylindric ends of the membrane are clamped to clamping assemblies mounted on the inside of the hopper adjacent its upper and lower ends, respectively, without the use of fasteners extending through holes in the ends of the membrane or other means of attachment to the hopper. The clamping assemblies are removable from the hopper with-out first unclamping the membrane whereby the clamping assemblies and membrane may be readily installed in and removed from the hopper.  Pressurized air is introduced into the hopper through the hopper walls and passes inwardly through the membrane with the stay bars in the membrane preventing substantial inward billowing.  After passing through the membrane, the air enters into fluent material contained within the hopper thereby to fluidize the material for efficient unloading from the hopper.

Abstract: INFRARED STEREO SPEAKER SYSTEM                   Abstract of the Disclosure A stereophonic audio system including a device for providing a stereophonic signal, such as an audio receiver.  An i  infrared transmitter connected to the receiver converts the audio signal to an infrared signal to be radiated throughout a signal area.  Within this signal area is disposed a pair of loudspeakers, each selecting a separate portion of the infrared signal, converting that one portion of the infrared signal to an audible sound signal, and radiating the sound throughout a listening area.  Each loudspeaker includes a filter for select-ing the one infrared signal which applies to it.  The transmit-ter includes a plug engageable with a headphone jack of the receiver for electrically connecting the transmitter to the receiver and an infrared diode array for radiating the signal within the signal area.  Each of the loudspeakers includes a photodiode arrangement for receiving the infrared light carrying the transmission signal from the transmitter and passing it to the respective filter, an  amplifier for amplifying the signal, and speaker elements for receiving the signal from the amplifier and converting it to sound signals, for radiating in the listening area.  To avoid the necessity of any wires leading to the loudspeakers, each is battery operated, and includes a power saver circuit to reduce power loss whenever no signal is received from the transmitter.  The transmitter also includes a power saver circuit to disable the diode array whenever it receives no signal from the receiver.

Title: Multiphase fluid mass transfer pump
Inventor: MASSINON ROLAND M J
IPC: F04B1/00
Filed: 1989-05-05
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE           A positive displacement piston pump that can pump multiphase fluids by separating the fluid into its different components inside the pump before pumping the fluids. A reciprocating piston mounted inside the pump barrel divides the barrel into two chambers, with each chamber having an opening.          Accumulators located above the chambers and below the pump inlet. provide a space for the multiphase fluids entering the pump to separate before entering the chamber.  As the multiphase enters each accumulator, gravity causes the liquid to sink and the to rise separating the different phases, preferably allowing liquid to enter the chambers before the gas.  When the piston moves through the chambers forcing the fluid through outlet valves locked on the top side of the chamber the as will exit the chamber, the accumulator, and the pump before the liquids.        The piston moves through the pump barrel in one direction causing the chamber in that direction to decrease in volume thereby forcing the multiphase fluid in that chamber out through an outlet valve and into the pipeline.  Simultaneously, fluid from the source pipeline is drawn into the other chamber comprised of the part of the pump barrel in a direction opposite the movement of the piston.

Abstract: Abstract of the Disclosure An apparatus and method for centrifugally separating the component species of a mixture, at least one of which species is a fluid, when the mixture includes at least one or more species of specific weight different from that of the fluid.  The mixture is fed tangentially into the inlet end of a converging nozzle, at high speed, to establish an axial helical flow path of the mixture.  As the mixture moves along the converging nozzle, generally the lighter species collect in the center and the heavier ones collect at the outside wall.  A throat of constant diameter or slightly converging angle may follow the nozzle.  As the mixture moves through the throat, the radial separation is maintained similarly as in the nozzle.  A diverging diffuser is located downstream of the throat and a throttle valve element is located at least partially within the diverging diffuser.  The throttle valve element controls the size of the diffuser gap between the throttle valve element and the diffuser.  This controls outlet area and thus flow of the mixture.  The lighter species are generally extracted through one or more axially-centered openings in the throttle valve element, while heavier species exit through the diffuser gap.  Heavy species can also be collected through one or more openings in the throat wall.
