Title: Treatment of liquids
Inventor: BURT DAVID A
IPC: B01D21/00
Filed: 1990-07-11
Abstract: Liquids, specifically liquids containing suspended matter, may be treated by passage through a separator comprising means dividing the container into a first section, intermediate section and third section, with a flat topped weir dividing the first section from the intermediate section.  The width of the flat topped weir is selected so that liquid flow over the weir is laminar.  At least the flat topped portion of the weir is provided with a smooth surface so as to reduce friction and boundary effects which distort the desired flow pattern.  This smooth surface may be constituted by an L-shaped stainless steel plate.  The interior side walls of the container in the vicinity of the flat top of the weir may be coated with a two-part epoxy to provide smooth surfaces.

Title: Apparatus for filling bottles and the like
Inventor: METTE MANFRED
IPC: B67C3/20
Filed: 1990-08-23
Abstract: ABSTRACT           Apparatus for admitting metered quantities of a liquid into discrete containers in the form of bottles, cans or the like has a rotary annular tank which carries at its underside a ring-shaped set of filling units each of which has a discrete metering vessel serving to receive a metered quantity of liquid from the interior of the tank for admission into a container which is placed into alignment with a centering and sealing sleeve movably mounted on each metering vessel.  If the liquid is to be admitted into the containers at an elevated pressure, the supply of liquid in the tank is disposed beneath a plenum chamber and each filling unit is designed to admit compressed gas from the plenum chamber into the aligned container prior to admission of a metered quantity of liquid.  The liquid which flows into a container expels the compressed gas which is returned into the plenum chamber or into a separate receptacle. The liquid-receiving capacity of the metering chamber in each vessel can be varied by an adjustable insert which can be manipulated from above the tank  The metering vessels can be located beneath the bottom wall of the tank or an upper section of each metering vessel can extend into the tank.

Abstract: An optical head for an optical disk recording/reproducing apparatus, which is capable of irradiating a recording medium by a light beam emitted from a light source and introducing an information light which is formed by the light beam reflected from the recording medium to a photo detecting system, while minimizing a shift of an optical axis of the information light.  The optical head includes a unit for receiving the information light which is reflected from the recording medium, a first reflecting unit for reflecting the information light received by the receiving unit, a second reflecting unit for reflecting the information light reflected by the first reflecting unit and for directing the reflected information light toward the photo detecting system, and a unit for emerging the information light reflected by the second reflecting unit to the photo detecting system.  The first reflecting unit has a surface for reflecting the information light thereby, and the second reflecting unit also has 2 surface for reflecting the reflected information light from the surface of the first reflecting unit.  The surface of the first reflecting unit is substantially parallel to the surface of the second reflecting unit.          The emerging surface has a surface for emerging the information light reflected by the surface of the second reflecting unit.  An angle between the surface of the receiving unit and the surface of the first reflecting unit substantially coincides with an angle between the surface of the second reflecting unit and the surface of the emerging unit.

Title: Fuel injector nozzle support
Inventor: ROBERTS HUBERT S JR
IPC: F23R3/14
Filed: 1991-08-08
Abstract: A fuel injector nozzle support includes a support plate joinable to a combustor dome and a ferrule slidably joined to the support plate. The ferrule includes a base, and a bore for slidably receiving a fuel injector nozzle.     The ferrule base has a noncircular perimeter and the support plate includes a receptacle for receiving the ferrule base which has an inner circumference being complementary to the ferrule base perimeter for presenting rotation of the ferrule base greater than a predetermined maximum rotation while allowing radial translation of the ferrule base for accommodating differential radial thermal movement of the fuel injector nozzle and the support plate. In an exemplary embodiment, the base perimeter and the receptacle have complementary straight and arcuate profiles, and the support plate is formed with counterrotational swirler vanes of a swirler fixedly supported to a combustor dome. The noncircular perimeter assembly eliminates the use of conventional antirotational lugs and stops.
Patent CA-2049355-A1 (CA)
Title: Drill stem test tools
Inventor: EDWARDS JEFFREY C
IPC: E21B34/10
Filed: 1990-03-27
Abstract: Once a new oil well has been drilled and cased, a test string is set in place for the purpose of evaluating the production potential of the chosen formation.  One way of controlling the operation of the various tools included in the downhole test string, including the opening and closing of the downhole valve itself, is by changes in the pressure differential between the tubing and the annular space which surrounds it in the well, but this requires the provision and maintenance of a fixed "reference" pressure within the tool, and a convenient such pressure is the hydrostatic (annulus) pressure experienced by the string after it has been lowered down the well bore and set into the packer.  The invention proposes that reference pressure within the test string be trapped by a novel mechanism wherein a valve (4) drivable into a closed position by a first piston (3) open (at 5) to annulus pressure first defines, and then defines and closes, the open-to-tubing-pressure entrance (6) to a passageway (30, 19) leading to a reference-gas-containing chamber (22) via a second piston (20) therewithin.  The invention also proposes a new mechanism by which compensation can be made for the effect of downhole temperature changes on the gas in a reference pressure chamber, in which mechanism there is a hydraulic-liquid-containing chamber (27) which is connected at one end, via a piston (25) thereat, to a vent (24) to annulus and at the other end to two "one-way" passageways (28,29) linking it to the reference-gas-containing chamber (22) via a chamber-contained second piston (23).

Abstract: A graft copolymer is formed by graft-polymerizing 10 - 95 wt. parts of a vinyl monomer onto 5 - 90 wt. parts of the rubber polymer which comprises 40 - 99 wt. % of butadiene and 1 - 60 wt. % of an aromatic polycyclic vinyl monomer represented by the following formula (I) or (II):         Formula (I)              Formula (II)                        , or wherein R denotes a hydrogen atom or a methyl group.                 The graft copolymer is characterized by the rubber polymer having a high refractive index as well as a low glass transition temperature due to the use of the aromatic polycyclic vinyl monomer.  Accordingly, the graft copolymer per se may be used as a thermoplastic resin having good transparency and impact resistance at a low rubber polymer content and may also be added to a transparent thermoplastic resin inclusive of a vinyl chloride resin and a styrene-acrylonitrile copolymer resin to provide the thermoplastic resin with an improved impact resistance while retaining a good transparency.
