Title: Process for hide tanning.
Inventor: LEUCK CARLOS ALFREDO
IPC: C14C1/08
Filed: 1997-07-30
Abstract: The present invention refers to a new process destined to the tanning of hide to the chrome and/or to the tanine. The process proposed by the invention comprises the following steps of cleansing or cleaning the skin, conditioning and tanning the chrome and/or the tanine. The conditioning uses the hydroxybutanal which reactions blocking the amines of the colagene and freeing carboxylas. This reaction reduces the isoelectric point for 4.0 to 4,5 taking the susceptible skin to effective tanning to the chrome joined to the carboxylas, or to the tanine joined by hydrogen bridges. The hydroxybutanal is used in the conditioning in the proportion of 2,5 to 3,0 percent on the weight of the skin exempt from lime, in the concentration of 40 +- 2 percent and with a pH of 4,2 to 4,k4 the reaction time being of 3 to 4 hours.

Title: Deforming thermoplastic tube into double pipe sockets - in mould with pressurised gas followed by pressurised coolant flow
IPC: B29C49/18
Filed: 1975-09-24
Abstract: The tube is deformed by raising it to at least its plasticising temp. and enclosing it in a mould. An enclosed cavity is formed inside the mould and this is filled with a gaseous pressurised medium; the pressure being maintained in the tube. When deformation is complete, the tube is filled with a coolant under pressure, - at 10 atm. as against 6 atm. for the gaseous medium, which is pumped through in a constant flow. Pref. freshly extruded and cut off blanks are used to form double sockets for pressure lines. Fittings from deformed tubes withstand higher loading than those formed by die casting. The technique enables the deformed pipe to be stabilised and cooled quickly enough to permit the use of directly extruded blanks.

Title: Geothermal energy system using naturally hot dry rock - includes pumping water through underground chamber where contact area is increased by fracturing
IPC: E21B43/26
Filed: 1980-04-28
Abstract: The system for extracting geothermal energy from hot dry rocks includes the use of a number of bore holes drilled vertically down to the depth at which the hot rock is found. In the region where the rock is hot the holes deviate from the vertical line to pass through the hot region. The pipes which may be in pairs are provided for pumping water in and pumping out heated water. At intervals along the inclined portions of the pipes a number of vertical fractures are formed. These are made by applying hydraulic pressure. This increases the area of contact between the rock and the water, overcoming problems arising because of the poor conductivity of rock. An insulation above ground makes use of the heat energy extracted in this way.
