Patent EP-1181252-B1 (EP)
Inventor: BAKKE RUNE
IPC: C02F3/28

Granted: 2004-04-28
Abstract: The present invention relates to a method for treatment of organic material, grown for energy production or being organic waste which is slurried, suspended or dissolved in liquid, in a two-step anaerobic biochemical reactor configuration comprising recirculation between the two reactors. The organic material is fed to the first reactor where most of the hydrolysis and dissolution of the organic material takes place, resulting in formation of volatile fatty acids (VFA). Liquid material from the first reactor is transferred to the second, methanogenesis reactor where the treatment is finalized. The amount of VFA in each reactor is forced to oscillate within pre-set upper and lower limits by pulsed recirculation between the two reactors. The amount of VFA in the reactors can be controlled by varying the recirculation rate of liquid between the reactors. The pH or the conductivity in the reactors can be monitored and used for calculating and controlling the amount of VFA in both reactors.

Abstract: L'invention concerne un procédé permettant de récupérer du 3,4-époxy-1-butène à partir des effluents en phase vapeur d'un réacteur d'oxydation catalytique, dans lequel on fait réagir du 1,3-butadiène avec de l'oxygène sur un catalyseur à l'argent. Ledit procédé consiste à mettre les effluents du réacteur au contact d'un agent d'absorption dans un absorbeur, et à vaporiser dans l'absorbeur un quantité efficace de réfrigérant non réactif de manière à refroidir l'absorbeur pour atteindre une température inférieure à 40 °C environ et une pression inférieure à 4 bars environ. La vaporisation du réfrigérant non réactif à proximité de l'absorbeur présente l'avantage de permettre le fonctionnement de l'absorbeur à des températures et pressions inférieures à celles qu'il était possible d'obtenir jusqu'à présent, et de tolérer des concentrations en O2 supérieures au niveau de l'alimentation du réacteur d'époxydation.

Title: A hollow piston wave capture pump apparatus and process for harnessing energy from aquatic waves
Inventor: WALL BRIAN
IPC: F03B13/00
Filed: 2014-06-20
Abstract: The present invention relates to the exploitation of energy in aquatic waves. In particular, the invention provides a hollow piston wave capture pump, which consists of a hollow piston contained in a buoyant water/air capture unit mounted on a compressor unit, mounted on an adjustable floatation tower, bearing a stability plate, to which mooring ropes and anchors are connected. The advantage of the invention is that the body of the structure remains static while the buoyant water/air capture unit rises with each wave, drawing air into the compressor unit while collecting water from each wave to fill the hollow piston. As the wave retreats, the captured air in the compressor unit or another mechanism delays the descent of the hollow piston so that the downward force of the captured water compresses the air to the maximum extent for immediate exploitation or forces it into storage for exploitation later. <Figure 2>

Abstract: In a process for knitting a weft-knitted fabric (T) by means of mutually opposite needlebeds comprising axially slidable needles, the needles being operated in correspondence to a yarn feed, said yarn consisting in a base thread (FF) and a pile thread (Fp) mutually coupled, for stitches in correspondence with which pile has to be formed, when the needle is engaging the yarn, the pile thread (Fp) is separated from said base thread (FF) and retained so that a bridle (B) is formed on the backside between the new stitch and the previous stitch of the same rank (R), while the base thread (FF) forms a normal backside stitch lower loop. The bridle (B) is subsequently cut in order to obtain the cut pile, as the fabric under formation progressively moves down. The invention also relates to a knitting machine specifically designed and built for carrying out the process and to a knitted fabric obtainable with such process and machine.

Abstract: A lock device comprising a lock housing (20) and a latch bolt (10), which is movably arranged in an opening (22) in the lock forend of the lock housing. The bolt (10) is movable between an outer position, in which it projects out from the lock housing, and an inner position in which it is essentially withdrawn into the housing. The latch bolt has an oblique outer end surface and can rotate about a longitudinal axis in an uncontrolled fashion, and is outwardly biased by spring means. The bolt also includes a holding side (13a) and a striking side (13b), said sides being straight and generally parallel with one another. The bolt also includes two mutually opposing curved sides (14), wherein each of the curved sides forms a circular arc that has a common centre of arc and that coincides with the longitudinal axis. As a result, the latch bolt obtains a better engagement function, which reduces the wear and load on the lock device and therewith increases its length of useful life.

Abstract: A continuous machine for the manufacture of fiber-containing materials such as paper, which comprises a rotating cylinder partly immersed in a body of liquid containing fibers in suspension. The surface of the cylinder comprises permeable and impermeable areas arranged in a predetermined pattern, and fibers are drawn onto the permeable areas by suction from within the cylinder, the layers of fibers formed on these areas being transferred to a conveyor belt which contacts the cylinder surface at a zone out of contact with the liquid. The surface of the cylinder is washed upstream of the transfer zone to remove fibers and other particles which may adhere to the impermeable areas of the cylinder surface by feeding cleansing liquid, such as pure water, across an overflow edge into a space adjacent the cylinder so that the cleansing liquid flows parallel to the impermeable areas.
