Abstract: COFFEE BREWING APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE     A  coffee  brewing  device  includes  a housing  for holding ground coffee with at least one wall of the housing being  formed from a permeable filtering membrane which permits  a  flow-through  of  water.   The  interior  of  the housing  is  vented  to  the  atmosphere  through an attached conduit, which can be used as a handle, so as to permit the escape of gases which are generated when the coffee grounds are submerged in a cup of hot water.  Baffles which serve to control  the extent and  direction of  gas movement may  be positioned in the housing.  By such control, the generated gases may be utilized to agitate the coffee grounds to thus get a more complete mixing of the grounds with the water prior  to a  venting  of  the  gases to the atmosphere.   The baffles  may  be  of  both  a  perforated  and  non-perforated design so as to control gas bubble size and direction of flow.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuous hydrolysis process for the hydrolysis of wood and wood derived products into sugars and other products has an overall countercurrent flow of liquids and solids but an integral co-current flow of the liquids and solids as part of the process.  Woodchip or other feedstock is formed into a slurry which is acidified, pressurised and heated before being hydrolysed in reactors.  Three heat exchangers form a closed circuit in which a second heat exchanger recovers heat from the slurry, a first heat exchanger returns heat to the slurry and a third heat exchanger makes up lost heat.  The slurry is cooled before pressure reduction by pressure reducing means and separation of the solids and liquid.  The cooling prevents flashing to steam of part of the liquid in the slurry so that the process is single phase where generation of steam is avoided.  After separation the solids can proceed to further processing or to discharge as lignin.  The liquid can proceed to further processing or discharge.  By adopting this process, the leaching of wood and removal of sugar and lignins can be operated continuously at a low heat energy using a simple reactor.

Abstract: ABSTRACT OF THE DISCLOSURE     Process for the generation of chlorine dioxide by the essentially instantaneous reaction of a relatively concentrated aqueous solution of a metal chlorite and an oxidizing agent, preferably gaseous chlorine.  The reaction is carried out in a generator having a mix and dwell premix chamber interconnected with a source of vacuum, preferably a venturi.  The relatively concentrated aqueous metal chlorite solution and the oxidizing agent are allowed to mix and react in the premix chamber prior to any dilution as, for example, by water or other fluid flowing through the venturi eductor to deliver the generated chlorine dioxide to storage or utilization.  When the oxidizing agent is chlorine, it is preferred for the chlorine stream to contain some bleed water in an amount below that which would significantly dilute the reactants and thereby have a quenching effect on the reaction.  The presence of bleed water prevents a buildup of metal chloride on the chlorine inlet to the premix chamber.
