Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides a diffusion apparatus for the diffusion of a gas into a liquid comprising:  a pair of semi-permeable membranes each having first and second opposing surfaces and arranged with the first surfaces facing one another and the second surfaces facing away from one another, the semi-permeable membranes each being permeable to at least a portion of the gas; a first introduction arrangement for introducing said gas between the pair of semi-permeable membranes to be conducted along the first surfaces thereof; a pair of spacing plates arranged in juxtaposition to the second surfaces of the pair of semi-permeable membranes, the spacing plates including flow channels therein for conducting the liquid along the second surfaces of the-semi-permeable membranes; a second introduction arrangement for introducing said liquid into the flow channels of the spacing plates to be conducted therethrough along the second surfaces of the semi-permeable membranes, whereby at least a first part of the portion of the gas diffuses through the semi-permeable membranes into the liquid to form bubbles of the diffused gas of a first size in the liquid; and a mixing arrangement associated with each of the semi-permeable membranes for directly mixing the second part of the gas into the liquid as the liquid is conducted through the flow channels along the second surfaces of the semi-permeable membranes so as to form bubbles of a second size larger than the first size in the liquid.          A third fluid may be employed for heating purposes.                                     .

Abstract: APPLICATION OF:  EUGENE STRATYNSKI and KEITH ZUKAUSKY        FOR:  VALVE ASSEMBLY                      A B S T R A C T           A valve assembly of the type providing bypass flow through a branch channel when the movable valve member is in the closed position to block flow through the main flow channel outlet.  A venturi device is disposed in the main channel upstream of the movable valve member, and the venturi has secondary ports provided through the wall at the throat section.  When the movable valve member is in the closed position, flow into the venturi exits at the flow ports and flows through the bypass channel.  When the movable valve member is in the open position, flow dis-charges from the venturi, through the main channel outlet port downstream of the movable valve member, thereby causing reduced pressure at the venturi throat and preventing flow through the secondary ports to the bypass channel.

Abstract: Abstract of the Invention A bottle Orientation Unit comprises a bottle feed device for moving bottles of a predetermined configuration along a pre-determined path.  A sensing station is located along the pre-determined path.  A sensing apparatus is disposed at the sensing station for sensing a predetermined characteristic of each bottle indicative of the bottles orientation as each bottle moves along the predetermined path.  A bottle orientation station is located along the predetermined path after the sensing apparatus.          A gate device is disposed at the bottle orientation station and is operative between a first and a second condition for on-gaging the neck of each bottle whereby the bottle is oriented into a base leading position along the predetermined path.  A control apparatus is responsive to the sensing apparatus and the gate device for operating the gate device between the two condi-tions whereby the bottle is orientated into a base leading posi-tion.  The sensing apparatus of the present invention comprises a position sensing device operative in response to the movement of a bottle into the sensing station on the predetermined path for providing a position signal to the control apparatus.  An orienta-tion sensing device is operative in response to the position signal for sensing a predetermined characteristics of each bottle and sending a characteristic signal to the control apparatus upon which the gate device is responsive.

Abstract: VACUUM SYSTEM FOR SWIIMMING POOLS     ABSTRACT OF TH DISCLOSURE        The customary method to prepare the pool bottoms in order to install the vinyl liners is with even, smooth surfaces.  Difficulties occur when draining a vinyl liner pool in order to change the water, repair the liner, clean the grease from the liner, or remove the impurities from the pool bottom.  In the method which I propose, the pool bottom is finished with plastic or rubber tiles which are pitched in the ground.  The upper surface of the tiles is deeply impressed with geometrical designs and cramped channels which allow the vacuum of the underliner air towards a permanent vacuum system at any time.  Thus, whenever it is necessary, the liner is sucked to the pool bottom by higher pressures than the normal water pressure of the pool, and the liner maintains its shape firmly until the pool is able to be refilled.

Abstract: TITLE.    METAL-TO-METAL SEAT HUB SEALS            ABSTRACT      A valve has a metal-to-metal seal system between the flow bores of the valve body housing and each of the valve seat hubs.  Each seal system includes an elastic dished metal ring gasket and a retainer ring.  Each metal gasket is softer than each of the seat hub and the valve housing, is of rectangular cross-section, and the edge at the inner periphery on the convex side is flattened.  Each seal system is disposed on an annular groove cut in the outer periphery surface of the end of the seat hub.  One side of the metal ring gasket is located adjacent to the shoulder of the seat hub formed by the groove cut into the outer periphery end of the seat hub.  The retainer ring is recipro-cably mounted on the seat hub groove adjacent to the other side of the metal ring gasket and extends beyond the end of the seat hub prior to activation of the seal system.  Each seal system is activated by insertion of the seat hub on which it is mounted into the corresponding bore of the valve housing until the end of the seat hub contacts a stop shoulder in the bore.  The stop shoulder of the valve bore causes the retainer ring to advance towards the seat hub shoulder far enough to flatten out the dished metal ring gasket sufficiently for the inner and outer peripheries of the ring gasket to engage the wall of the groove of the seat hub and the wall of the bore respectively with enough pressure to cause plastic deformation of the inner peripheral edge on the concave side and the outer peripheral edge on the convex side of the gasket.  The retainer ring also prevents substantial movement of the seal relative to the seat hub and housing when the valve is in use despite variations in the tempera-ture of the valve and the pressure of the fluid therein and thereabout.

Abstract: ABSTRACT    An improved immobilized enzyme composite is prepared by subjecting a siliceous carrier to an initial treatment with alkali, then acid, then reacting the carrier with an organosilane.  The organosilane may then be coupled through a covalent coupling agent with an enzyme.  The alkali-acid treatment provide   n exceptionally high number of hydroxyl groups per unit volume. so that the treated carrier is especially useful in the preparation of high performance immobilized enzyme compositions, particularly by multi-layering immobilization, providing a very high amount of enzyme activity per unit volume. Multi-layering is accomplished by successive steps of bonding a difunctional covalent coupling agent to a previously immobilized enzyme layer, then bonding an additional layer of enzyme to the coupling agent.  This may be repeated to apply as many layers as desired.

Abstract: ABSTRACT OF DISCLOSURE              Specific Surface Fractionator The specific surface distribution of a pulp may be obtained by pumping a sample at a pressure to overcome the pressure drop of a plurality of hydro cyclones arranged in series with the apex of leading hydrocyclones connected to the inlet of the next hydrocyclone, etc. in the series.   Back pressure is maintained on the base outlet of said leading hydrocyclone, the consistency of the feed to the first hydrocyclone is sufficiently low to ensure that the consistency of the fraction rejected from the apex outlet of the penultimate hydrocyclone in the series is adequate for efficient separation in the final hydrocyclone of the series i.e. to have a feed consis-tency not exceeding about 0.25% to the last hydrocyclone in the series.  Samples are collected from outlets from the hydrocyclones and may be tested to determine specific surface thereby to obtain an indication of the specific surface distribution of the pulp.
