Granted: 1993-08-24
Abstract: 183/2?     ABSTRACT OF THE DISCLOSURE          A hydraulic control device for a continuously variable vehicle transmission having a closed hydraulic circuit disposed between a hydraulic pump and a hydraulic motor, with at least one of said hydraulic pump and said hydraulic motor being of the variable displacement type.  The hydraulic pump is driven by an engine and the hydraulic motor is connected to the road wheels and is driven by hydraulic pressure from the hydraulic pump.  A pair or relief valves are disposed between the two oil passages of the closed hydraulic circuit extending between the hydraulic pump and the hydraulic motor, each of which are for relieving the pressure from one oil passage to the other oil passage.  One relief valve relieves the pressure from the oil passage which has the higher pressure when the continuously variable transmission is driven by driving forces from the engine to drive the road wheels, and has a relief pressure setting controlled so as to increase as the speed of rotation of the engine increases.  The other relief valve which relieves the pressure from the other oil passage which increases in pressure when said continuously variable transmission receives driving forces from the road wheels, has a relief pressure setting controlled so as to increase as the speed of the motor vehicle increases.

Granted: 1995-11-21
Abstract: A refrigerated container 2 has associated therewith a compressor 6 which receives filtered air and passes it to a small apparatus 12 for separating air by pressure swing adsorption or by different rates of permeation  of gas through semi-permeable membranes.  Resulting air depleted in oxygen and water vapour flows into the interior of the container 2 and displaces atmosphere from the container 2 through a vent tube 20.  Reducing the oxygen and water vapour content of the atmosphere in the container 2 (which may be a refrigerator or freezer) helps to preserve food stored therein and reduces the deposition of water or ice.

Abstract: The present invention relates to a method and apparatus for treating fiber suspension. The method and apparatus in accordance with the present invention is especially suitable for treating the fiber suspensions of the wood processing industry, for example, in thickening or washing pulp. The methods and apparatuses in accordance with prior art techniques have recently been based on using vacuum filters. In other words, the separation of liquid from the pulp has been based on the fact that an underpressure has been arranged on one side of the pulp cake, whereby the external atmospheric pressure has displaced liquid in the pulp. Thereby air has passed into the pulp causing slime problems among other things. On the other hand, a drawback with such apparatus has been their poor ability to utilize the filter surface, because only 50 - 60 % of the total filter surface area has even under the best conditions being efficiently used. The method and apparatus in accordance with the present invention enables the use of almost the whole filter surface by arranging the pressurized feed of the pulp to the apparatus, whereby liquid is separated due the lower pressure, for example the normal atmospheric pressure prevailing behind the filter surface. On the other hand, the discharge of the pulp cake has been arranged to be carried out from only a very limited portion of the filter surface, whereby the use of the filter surface area is even further intensified.
