Title: Hydrolysis of lignocellulosic materials
Inventor: FRITZE HARTWIG
IPC: C13K1/02
Filed: 1984-08-09
Abstract: A process for the hydrolysis at high pressures and temperatures of organic matter with a ligno- cellulose content, particularly ground wood, bagasse and corn on the cob waste comprises three steps, whereby the fractions of the organic matter, namely pentoses, lignin and hexoses are separated from one another in succession in separate steps in the process. Both prehydrolysis for separating out the pentoses and the main hydrolysis process for separating out the hexoses are performed at elevated temperatures and pressures with a high degree of mechanical treatment in a dispersing reactor. The resulting sugars are prevented from dissociating by means of rapid cooling by flash evaporation. The ligno-cellulose aggregate, freed of pentoses. is conveyed off for further splitting in order to remove the lignin after which the remaining organic matter, comprised overwhelmingly of cellulose, is submitted to the main hydrolysis process as a result of which highly concentrated glucose is extracted for the production of ethyl alcohol.

Title: Fuel supply path in a gas turbine engine
Inventor: SMITH RAYMOND
IPC: F02C7/22
Filed: 1987-06-30
Abstract: The main shaft of the engine comprises a fuel tube 72 extending axially through the shaft, a first shaft wall 82 and the second shaft 84 wall spaced apart from each other at one end of the tube to define a flow passage therebetween, a plurality of vanes 78 extending across the passageway, an annular cavity 86 in fluid communication with the outlet of the vaned passageway and a plurality of circumferentially spaced injector nozzles 58 in fluid communication with the annular cavity and opening into the combustion chamber 42 of the engine. The vanes 78 impart sufficient energy to the fuel to overcome friction losses in the injector nozzles and to overcome the pressure within the combustor chamber. In addition, the energy imparted to the fuel forms a fuel barrier which separates the combustor chamber pressure from pressure within the fuel tube. Fuel is delivered to the fuel tube by pumping and metering means which can be downsized from previously known fuel pump mechanisms since it only needs to meter a desired amount of fuel and provide pressure only to overcome friction losses in the flow path up to the fuel tube.
