Title: Separation of wort from mash
Inventor: DAOUD IYADH S
IPC: B01D29/25
Filed: 1987-10-16
Granted: 1991-11-12
Abstract: ABSTRACT                  Separation of Wort from Mash A barrier cross-flow separation method is used to separate wort from mash in  beermaking.  The separator medium is preferably a cylindrical element with an internal diameter of at least 20mm and a pore size in a range of from 10 µm to 100 µm.  High gravity wort is obtainable from a four-step separation process which can handle mash free of husk and including large amounts of cereal adjunct.  The wort may be clarified in a subsequent filtering step.

Title: Viscous oil recovery method

Granted: 1991-01-22
Abstract: VISCOUS OIL RECOVERY METHOD        (D# 78,631-F) ABSTRACT Our invention concerns a method for treating a well completed in a subterranean petroleum-containing formation which will improve the rate at which steam can be injected into the formation for a steam push-pull or steam drive oil recovery method.  This preconditioning process is applied to formations exhibiting very limited steam receptivity because the formation contains high oil viscosity and has high oil saturation and is completely liquid filled.  The method involves injecting a mix-ture of a non-condensable oil-insoluble gas such as nitrogen and an oil soluble gas such as carbon dioxide all in the gaseous phase into the formation at a controlled rate which will avoid permanently fracturing the formation and also avoid the immediate formation of an oil bank due to dissolution of the injected oil soluble gaseous fluid into the oil.  Ideally by controlling the injection rate, the gaseous mixture first displaces water from the flow channels and then carbon dioxide slowly dissolves in the oil while nitrogen remains in the flow channels.  Steam injection can then be applied to the formation without the previously experienced loss in steam injectivity.

Abstract: ABSTRACT OF THE DISCLOSURE    A novel device is provided hereto for automatically adjusting the length of the sheath of a bowden cable, such bowden cable being capable of transmitting substantial forces.  The bowden-cable sheath terminates in a sleeve with a stepped outside diameter so that it can be inserted into a structure-fixed housing against the force of a compression spring.  The housing contains a set of spacer panes which are spring-loaded and which rest on the large diameter of the sleeve and which, upon displacement of the sleeve out of the housing, sequentially drop onto the small sleeve diameter.  The dropped panes extend the sheath each time by their thickness.  Such spacer panes form the support, between the sleeve collar and the housing inside wall, for the force exerted on the bowden cable.  In a special embodiment, the device is equipped with mechanical means accessible from the outside which, when actuated, will reset the already dropped spacer panes into their initial positions.          Another embodiment offers the possibility to reset the spacer panes into their initial positions by shaping the sleeve so asymmetrically that these spacer panes can be returned to their initial positions by a 90° rotation of the sleeve and by displacing this sleeve into the end fitting and rotating the sleeve back to its original position.  This embodiment is closed on all sides and denies access to water, dirt, etc.
