Patent CA-1094296-A (CA)

Abstract: ABSTRACT         An apparatus and method are disclosed for effecting liquid-liquid contact.   An aqueous medium and an organic hydrophobic liquid medium are fed to a mixing chamber in which a "primary" dispersion, capable of disengaging substantially completely into two separate layers on standing under gravity, is formed by suitable mixing means.   Dispersion is allowed to flow upwardly and downwardly from the mixing chamber into upper and lower baffled zones positioned immediately above and below the mixing chamber respectively. Disengaged lighter medium is allowed to collect in an upper chamber above and communicating with the upper baffled zone, whilst disengaged heavier medium is allowed to collect in a lower chamber below and communicating with the lower baffled zone.   Heavier medium is allowed to return to the mixing chamber from the upper baffled zone and lighter medium from the lower baffled zone.   By removing the respective disengaged media from the upper and lower chambers at the same rates and in the same ratio as they are fed to the mixing chamber a favourable (e.g. 1:1) mixing ratio can be maintained in the mixing chamber despite a different (e.g. 5:1) volume feed ratio to the mixing chamber.

Abstract: WET METHOD OF PREPARING FIBERBOARD PRODUCTS IN A SUBSTANTIALLY CLOSED AND BALANCED WHITE WATER SYSTEM                 ABSTRACT OF THE DISCLOSURE   Wet method of making fiberboard products in a substantially closed white water system by applying one or more layers of sep-arately prepared surface pulp to a layer of base pulp at the wet sheet forming stage, which layers are subsequently hot pressed into the final product, while the volume of white water is main-tained substantially constant.  The base pulp is produced by treating the chips in a defibrator under generation of steam of predetermined superatmospheric pressure and corresponding elevated temperature. A major portion of the base pulp is diluted with white water drained off and recycled from the base layer wet sheet forming stage to form a base layer suspension, which is transported by the white water to the wet sheet forming stage, where the white water is drained off and recycled to the base layer suspension stage to form a new base layer suspension.  A smaller portion of the base pulp is further diluted with white water recycled in a separate closed circuit from the surface layer forming stage to form a surface layer suspension which is transported to the sur-face layer stage by the white water which is drained off to form a surface layer sheet and recycled to the surface layer suspension stage to form new surface layer suspensions.

Title: Orifice trim and backpressure plate for high pressure valves
Inventor: SCHNALL IRA H
IPC: F16L55/02
Filed: 1978-07-27
Granted: 1981-05-05
Abstract: ABSTRACT OF THE DISCLOSURE           A new and improved fluid restrictor means is disclosed for use in a valve structure, as a backpressure plate, or the like and generally comprises a plurality of close-fitting mating parts each of said parts including a plurality of openings spaced across the surface thereof.  The mating parts are rigid in construction and arranged and configured whereby they are in a contacting relationship and the openings of contiguous mating parts are in an overlapping relation to form restricting orifices for flow communi-cation between complementary openings.  The volume of each of the openings is sufficient to form an expansion chamber for high pressure fluid flowing through the restrictor means.  The disclosed fluid restrictor means provides a structure which is easily arranged according to precise engineering specifications for a particular application.  For example, all of the dimensions for the expansion chambers and restricting orifices are determined by the size of the openings in the mating parts, the thickness of the parts and the relative positions of the mating parts when in the final assembled form.  These factors are determinable with great mathematical exactness and the present invention permits a highly precise implementation of the predetermined flow path characteristics into the structure of the disclosed fluid flow restrictor means.

Abstract: ABSTRACT      There is disclosed a circuit for providing a comparison signal representing phase relationship between a clock pulse train and a variable rate input pulse train,  The comparison signal can be used to synchronize clock and input pulse trains.  The circuit includes a phase difference measuring circuit providing a first signal porportional to phase difference between input pulse train and clock pulse train, the signal having related discontinuities at the points of minimum and maximum phase difference between input and clock pulse trains,  A second signal is generated repre-senting a selected value of phase difference, the selected value being greater than the minimum phase difference and less than the maximum phase difference.  First and second signals are then com-pared to provide a signal representing difference between the measured and selected values of phase difference.  The comparison signal thereby avoids the discontinuities at minimum and maximum values of phase difference by representing phase relationship between input and clock pulse trains relative to the selected value of phase difference rather than to the maximum or minimum values.  In a preferred embodiment, decoding circuitry decodes an input pulse train in self-clocking code to provide data output in binary code.

Abstract: ABSTRACT         A waterborne air cushion vehicle is disclosed which has a flat rigid upper rectangular sheet-like platform.  A plurality of flat rigid longitudinal walls are attached substantially at right angles to the plat-form and depend therefrom substantially parallel with the major axis of the platform.  The outermost two of the walls are disposed as sidewalls along the respective edges of the platform.  A plurality of longitudinally spaced laterally aligned arrays of flexible trough-shaped skirts are respectively looped with a space therein and fastened via each longitudinal edge thereof with respect to the underside of the platform flush with but independently movable with respect to adjacent pairs of the walls but extendable to a lesser depth than that of the walls.  Pressurised air is admissible via apertures of fixed size at a relatively higher pressure to the skirts and also admissible at a relatively lower pressure via variable-sized openings remotely controlled and located respectively beneath the platform in com-munication with at least four square or rectangular open-bottomed air cushion chambers disposed laterally in pairs and each bounded by an adjacent pair of the skirts and by an adjacent pair of the walls.  The depth of the walls and of the skirts is so related to the flow rate of the air that the vehicle is buoyant upon water with the walls protruding into the water sufficiently to prevent air spillage via the walls when the vehicle is urged longitudinal-ly through the water by propulsion means.  The skirt air inlet openings are adapted to re-admit by reverse flow at least part of the compressed air in any one of the skirts independently in response to fugitive deflection of the skirts resulting from turbulence of the water, to thereby inhibit move-ment of the vehicle about the pitch axis thereof.  Each skirt is a bag-like structure adapted to resist changes in its cross-sectional shape under load by virtue of captive air therein.
