Abstract: David M. Haugen et al HYDRAULICALLY ACTUATED DOWNHOLE VALVE APPARATUS AND METHOD FOR TESTING FORMATIONS.                     ABSTRACT OF DISCLOSURE    An elongated valve means is operable between a closed and opened position and is connected to a tubing string for flowing fluid along an isolated flow path from a location downhole in a wellbore to the surface.  The valve means includes a main housing within which a mandrel is axially aligned.  A packer divides the borehole annulus into and upper and lower annular area.  The valve device includes an annular power chamber formed between the mandrel and the main body, and slidably receives a power piston therewithin.  The power piston is connected to a medial part of the mandrel.  Metered flow from the upper borehole is indirectly effected on the piston face, thereby driving the piston uphole and carrying the mandrel therewith.  The lower end of the mandrel has ports formed through a sidewall thereof which are brought into registry with a complementary port formed through the sidewall of the main housing.  The housing port is in fluid communi-cation with the lower borehole annulus.  Detects formed in the mandrel are engageable by a latch means which positions the mandrel axially as the ports are brought into registry with one another.  The latch means is retracted by a piston operated arm.  Fluid pressure from the upper borehole annulus indirectly actuates the piston operated arm.  The movement of the piston actuated arm and the power piston sequentially occur so that the latch means successively engages adjacent detents while successive ones of the mandrel ports are brought into registry with the port of the housing.  Accordingly, the valve means is opened to admit fluid thereinto and up to the surface of the ground, whereupon, the valve means is then moved to a first closed position, and thereafter again moved into the open position in response to hydrostatic pressure alter-nately being effected within the upper borehole annulus.

Title: Liquid circulating device
Inventor: WEBER LEO D
IPC: B01F15/02
Filed: 1992-03-26
Abstract: LIQUID CIRCULATING DEVICE                  Abstract of the Disclosure A liquid circulating device is provided for submersion in a large holding tank to effect continuous mixing and circulation of a liquid material,  such as sewage sludge,  contained therein in order to facilitate the digestion of the liquid material for environmentally  safe  disposal.   The  apparatus  of  the  present invention  includes  an  upright,  elongated  stackpipe  secured  to the floor of the holding tank and a gas bubble generator mounted to the stackpipe for generating gas bubbles into the stackpipe. The  gas  bubble generator  includes  an  interior  chamber  with  a substantially open bottom, a pair of baffle members transversely extending within the interior chamber and an inverted cone-shaped member positioned between, and in spaced adjacency to, each baffle member.  Gas under pressure is discharged into the interior cham-ber of the bubble generator by a gas supply line attached to an externally located compressor.  A well-formed, stable gas bubble created  in  the  interior chamber of  the bubble generator flows down a smooth upper surface portion of each baffle member and into the cone-shaped member which is  in flow communication with the stackpipe.   The continual generation of well-formed,  stable gas bubbles into the stackpipe propels the liquid material upwardly through  the  stackpipe  and  effects  the  circulation,  mixing and digestion of the contents.  The generation of well-formed, stable gas  bubbles  is  enhanced  by mounting  the  gas  bubble  generator directly to the stackpipe and not letting the gas bubbles loose between the gas bubble generator and the stackpipe.

Title: Multi-use gasoline/fuel pouring nozzle
Inventor: LEETE JEREMY S
IPC: B65D47/06
Filed: 1992-01-20
Abstract: Multi-use Gasoline/Fuel Pouring Nozzle ABSTRACT    This invention is a gasoline/fuel pouring nozzle apparatus for attachment to various vented gasoline/fuel containers having incorporated a removable base, an in-line fingertip controlled ball valve, and a removable closure key cap.  The nozzle may be designed using rigid plastic or with a flexible, accordion-like, snap-lock, segmented portion, intermediately conformed, to permit bending of the nozzle as the liquid is poured.  The removable base incorporates a filter which serves to strain the passing fluid and a gasket to provide a universal sealing mechanism.  It works with vented gasoline/fuel containers, cooperating in such a way that the container's existing screw cap is utilized for the attachment of the nozzle to the container.  To allow for storage and/or transportation, the nozzle can be inverted and stored internally within vented gasoline/fuel containers followed thereafter by the removable closure key cap and screw cap accordingly.  Additional base attachments can be provided so that the nozzle can be adapted to fit numerous other types of containers.  The ball valve is seated in fluid-tight relation between two rubber "O" rings, positioned near the base end portion of the nozzle.  The ball valve enables variable flow rate control from a closed to an unimpeded open position.  The removable closure key cap is a three-fold multifunctional mechanism which serves as a valve key for the operation of the ball valve.  Upon insertion of the removable closure key cap into the valve receptacle, the superimposed fluid flow passage through the ball valve may be opened, closed, or set at variable positions in-between by fingertip rotation of the valve key in a clockwise or counter-clockwise motion.  Furthermore, the removable closure key cap serves as the closure cap of the pouring nozzle and the container when the nozzle is internally stored.  The mechanism further serves as a grit cover that fits onto the narrowed tip section of the nozzle when the nozzle is assembled externally.

Abstract: An equivalent inductance circuit includes a feed-back type integration circuit and a differential amplifying circuit. An input signal applied to an input terminal is integrated by the feed-back type integration circuit and, a signal according to a difference component between an integrated output signal and the input signal is outputted by the differential amplifying circuit. By feeding the difference signal back to the input terminal, an input impedance equivalently represents an inductance characteristic. Such equivalent inductance can be changed by a current from a variable current source which supplies the current to the differential amplifying circuit and, a change of the equivalent inductance shows an inverse proportional manner.

Title: Hydrolysis of resin in pulp
Inventor: MALMGREN KENT
IPC: D21C9/00
Filed: 1990-11-07
Abstract: Resin can be hydrolyzed enzymatically during the peroxy bleaching (e.g. with hydrogen peroxide) commonly used in pulp manufacture and the use of lipase in the manufacture of CTMP-fluff will afford several significant advantages, such as a pronounced reduction in fats, low time-consumption, since the process can be carried out in less than one calendar day, no losses in brightness or yield, or only marginal brightness and yield losses, and low handling costs. The enzyme treatment during bleaching necessitates little or no change of commonly used bleaching conditions. As a further advantage, the peroxy bleaching is mostly made at alkaline pH, whereby the liberated fatty acids remain ionized and can thus easily be removed from the pulp during subsequent washing.
