Patent GB-976819-A (GB)
IPC: C01D15/04
Abstract: 976,819. Lithium fluoride; cryolite. KAISER ALUMINUM & CHEMICAL CORPORATION. Aug. 21, 1962, No. 32108/62. Heading C1A. Lithium is recovered from spent carbonaceous linings of electrolytic cells which have been exposed to lithium-containing electrolytes by crushing the linings and slurrying with an alkaline material to produce a cryolitic liquor and a black mud containing lithium values, aluminous material, and fluorinous material, the black mud is treated with a mixture containing lime to form lithium hydroxide which is then reacted with a fluoridic material to precipitate lithium fluoride. Fig. 1 shows the preferred method of operating the invention. The continuous and dash-dotted lines on the left hand side show the recovery of lithium fluoride from the black mud and the recovery of cryolite from the cryolite liquor by carbonation with carbon dioxide. The continuous lines on the right hand side show a cryolite synthesis process which is integrated with the cryolite recovery by the dotted lines. The proportions of cell linings and sodium hydroxide are adjusted to give a F- concentration in the cryolite liquor of 9-15 g./kg. The precipitation of lithium fluoride is preferably at a temperature between 80‹ and 100‹ C. Specifications 836,928 and 902,485 are referred to.

Title: Process for achieving the production run state in a web-fed printing machine
Inventor: ENDISCH MARTIN
IPC: B41F33/10
Filed: 1998-09-08
Abstract: By making the inking unit 7 drivable independently of the forme 6 or of the web 2 it is possible to pre-ink an inking unit 7, 7' and also to clean it when all the remaining rotating components of the printing machine 1 are stationary, in particular also with the print web 2 still in the machine. By means of a washing apparatus 27 to 30, 27' to 30' printing ink residues are removed from the inking unit 7, 7' until a defined initial state is obtained. Thereafter the inking unit 7, 7' is inked afresh according to subject-specific parameters, i.e. according to the printed image. This takes place in parallel during the startup of the printing machine 1. The ink application rollers 19 to 22 are then engaged with the forme cylinder 6 when the latter has reached the minimum speed of rotation required. This procedure reduces waste on start-up.

Title: Method of obtaining improved geophysical information about earth formations
Inventor: REIMERS NILS
IPC: E21B47/01
Filed: 1997-10-09
Abstract: The present invention provides a method for forming wellbores. In one method, one or more wellbores are drilled along preplanned paths based in part upon seismic surveys performed from the surface. An acoustic transmitter conveyed in such wellbores transmits acoustic signals at one or more frequencies within a range of frequencies at a plurality of spaced locations. A plurality of substantially serially spaced receivers in the wellbores and/or at surface receive signals reflected by the subsurface formations. The sensors may be permanently installed in the boreholes and could be fiber optic devices. The receiver signals are processed by conventional geophysical processing methods to obtain information about the subsurface formations. This information is utilized to update any prior seismographs to obtain higher resolution seismographs. The improved seismographs are then used to determine the profiles of the production wellbores to be drilled. Borehole seismic imaging may then be used to further improved the seismographs and to plan future wellbores. Cross-well tomography may be utilized to further update the seismographs to manage the reservoirs. The permanently installed sensors may also be used to monitor the progress of fracturing in nearby wells and thereby provide the necessary information for controlling fracturing operations.
