Title: Alkylation of aromatic hydrocarbons - using titanium tetrafluoride metal oxide catalyst
Inventor: RYU JI-YONG
IPC: B01J27/08
Filed: 1977-09-13
Abstract: Aromatic hydrocarbon is treated with an alkylating agent under conventional alkylating conditions in the presence of a catalyst consisting of TiF4 on a support contng. surface OH gps. The alkylation reaction is effected at lower temps. with increased throughputs. The catalysts are less corrosive and easier to handle than known catalysts, and are more stable to attack by H2O than the corresponding TiCl4 catalysts. In an example, a TiF4 catalyst was prepd. by treatment of pre-dried gamma-Al2O3 with TiF4 at 310 degrees under N2. Catalyst was then heated to 350 degrees then to 400 degrees to afford the product.

Title: Gas sample prodn. appts. used in absorption spectroscopy - has flow of inert gas dosed with sample gas by system of valves
Inventor: HUBER BERNHARD
IPC: G01N21/71
Filed: 1977-10-29
Abstract: The formation of a gas sample for deliverance to a flare point for atomic absorption spectroscopy or a measuring bowl, is controlled by the described appt. Inert gas enters along a conduit (10) to a branch point where it is directed along two paths (14) and (22) to an intermediate container (16). Regulable chokes (18) and (24) control gas flow in these pipes. Dosing of the gas in the chamber (16) by a reactive fluid takes place by flushing a sealed reservoir (30) with gas from conduit (14) by control of an isolator valve (20). Expanding gases pass to further processing stages through a controlled valve (40) while a pressure relief valve (36) dumps excess gas.

Title: Deuterium-hydrogen ratio spectrometric determn. - uses specimen enclosed in tube and cooled down to temp. safeguarding preset vapour pressure over specimen
Inventor: DUMKE INGOLF DIPL PHYS
IPC: G01J3/26
Filed: 1979-07-25
Abstract: The process is used for emission spectrometric determination of the deuterium-hydrogen ratio in marked water samples. The spectral lines of the water vapour components are produced by a high frequency induced gas discharge, while the triggering of the isotope spectral lines is carried out by a Fabry-Perot interferometer and the spectral line intensity is recorded. The sample is enclosed in a tube and cooled down to a temp., at which a presettable vapour pressure is produced over the sample. The excitation of the gas discharge is carried out with a low power, and the selection of a narrow spectral range about the H alpha-D alpha line is carried out. The interferometer separates two rings, geometrically corresponding to both lines, the intensity of both lines being measured by photodetectors and evaluated. Pref. the sample is frozen in a gas tube, which is sealed and cooled down again. The vapours are energised by a high frequency resonator.

Inventor: SDFELDT WOLFGANG ING GRAD
IPC: B24B9/00
Filed: 1979-07-26
Abstract: A method and a device for the automatic removal of burrs or fins from workpieces such as castings by a grinding process. A feed for moving the workpiece perpendicular to the grinding wheel radius is provided for grinding along the length of the burr. A second constant velocity feed of reversible and alternating direction is provided for moving the grinding wheel radially into the workpiece. The load or circumferential torque on the grinding wheel is monitored to detect the abrupt increase in torque occurring when the grinding wheel has cut through the burr and encounters the body of the workpiece, whereupon the direction of the radial feed is reversed so that the grinding process follows the contour of the workpiece.

Title: Dumping solid waste from coal sepn. - by taking coal flotation slurry and pumping this to centrifuge above tip for waste onto which solids discharge
Inventor: STRAUSS WERNER
IPC: C02F11/127
Filed: 1979-09-25
Abstract: Solid waste from the flotational sepn. of residues from coal is prepd. for tipping by centrifugation. The slurry is pumped to a centrifuge at the top of the tip where it is dewatered to below 30% water. The resulting centrifuge cake is then discharged onto the tip. All conveying to the tip is as a slurry. The system is to facilitate the dumping of the waste from coal mines. The process reduces the costs of tipping by avoiding the use of lorries and provides a means of making the sludge tippable by dewatering rendering it in a form in which it can be safely tipped without problems.
Patent DE-2944329-A1 (DE)
Inventor: SCHREIBER GEORG DIPL ING
IPC: B01J14/00
Filed: 1979-11-02
Abstract: A column (1) is used as an installation formed by a cascade mounting of columns, with a plurality of stages, comprising circulation chambers without stirrers for homogeneous liquid or gas systems which are susceptible to be modified by chemical reactions and/or physical processes by mixing in the circulation chambers. The column (1) comprises plates (3) succeeding each other at a distance, alternately inclined opposite with respect to each other and provided with a passageway (9, 6) at each of the lower and upper ends thereof. The fluid is introduced into the column (1) by means of a pump. The fluid stream is directed against the end area upstream of the inclined plates and deflected by said plates so as to form a jet (//c<uT>u) which gene rates a swirl of the homogenous medium in the circulation chamber and the suction of a fluid stream (//c<uS>u) outside the next chamber. This stream (//c<uS>u) sucked through a passage which is made free by a plate (3) flows again through the other passage (9) in the chamber outside which it has been sucked, so as to provide a loop shaped flow in the same way as the loop flow in a reactor. The swirl motion in the circulation chambers is obtained without a moving mechanical part.
