Patent AT-E3951-T1 (AT)
IPC: B01D3/40
Filed: 1980-03-18
Granted: 1983-07-15
Abstract: A process and apparatus are provided controlling the heat input of an extractive distillation column. The bottom of the column is heated with a major stream of thermal energy which is either slowly varying in time or controlled by the amount of starting material mixture and with a minor stream of thermal energy which is controlled by sensing the thermodynamic state in the upper half of the column during the process. The major stream can provide about 90 percent and the minor stream about 10 percent of the heat fed to the column. The minor stream can be controlled by the temperature at one point in the upper half of the column, by the temperature difference at two points in the upper half of the column or by gas chromatographic analysis of the extract material concentration near the top of the column. The process allows one to keep a low concentration of the extract material in the raffinate.

Abstract: A hydraulic control system with a pipeline antiburst safety device for a double acting drive cylinder, more particularly for adjusting and securing the position of a driven guide roller in the strand guide of a continuous casting plant which exerts an operationally conditioned reaction force, applied by the strand, on the piston of the drive cylinder. To prevent this reaction force causing the guide roller to retract in the event of a pipe burst, the control system substantially comprises a leakage-proof stop valve of cartridge construction disposed close to the drive cylinder and within the main control duct a leakage proof pilot valve situated close to the stop valve and having a spring-biased spool and a pressure retaining accumulator to maintain the pressure in the adjusting cylinder in the event of pressure failure in the main control duct, and a valve spool of the stop valve has three control surfaces and under normal position is in the closed position under the light pressure exerted by a compression spring which pressure can be overcome by an operationally conditioned pressure rise in the drive cylinder but in the event of a pipe burst the pilot valve changes over and momentarily replaces the absent pressure in the main control duct, normally biasing the control surface of the stop valve spool, by the pressure from the pressure retaining accumulator so that the stop valve remains in the closed position.

Abstract: A depth of cut adjustment mechanism for a portable power planer (20) having an adjustable front shoe (30) whose elevational position controls the depth of cut of the tool. An S-shaped rod (40) is fastened at one end to the adjustable front shoe (30) and is threadedly engaged at its other end to an adjustment nut (42) rotatably mounted in a race (44) formed in the housing (22). A control knob (46) having disposed thereon a scale (64) referenced to a mark (62) on the housing (22) is secured to the nut (42) so that rotation of the control knob (46) causes a corresponding adjustment in the elevational position of the front shoe (30). A tension spring (70) is connected between the front show (30) and the housing (22) to cancel out inherent tolerance play between the front shoe (30) and the housing (22).

Abstract: A regulator has a main valve connected between a first terminal of a d-c source and a first terminal of a load. A first series circuit poled similarly to the main valve and including a commutating valve in series with a commutating capacitor is connected in parallel with the main valve. Another series circuit including the commutating valve, a reversing valve and a reversing choke is connected in parallel with the main valve and conducts current in the same direction. A swingback valve is connected in parallel with the reversing valve and poled oppositely. A second choke is connected in series with the capacitor in the first series circuit and the end of the second choke connected to the first load terminal is also connected to a second line terminal by a first bypass diode poled to carry the load current, and a second bypass valve is connected between the second load terminal and the end of the second choke connected to the capacitor and is also poled to be conductive to current flowing in the load when the main valve is non-conductive. With the main valve blocked, a very small voltage can thereby be impressed on the load without the occurrence of overvoltages at the capacitor.

Abstract: Carbon electrodes are impregnated with pitch during transport in mobile vessels which first travel to a heating station where the electrodes are heated in several stages by gases which are hotter from stage to stage. The vessels next travels to a station where the sealed vessels are connected with a suction pump to evacuate the fluid from their interiors and from the pores of the electrodes therein and where the vessels are substantially filled with pitch which is caused to penetrate into the empty pores. The vessels then travel to a station where the contents of the vessels are pressurized to ensure complete permeation of electrodes with pitch. The vessels subsequently travel an optional station where the electrodes in the vessels are baked to convert the pitch into coke, and to one or more cooling stations where the electrodes are heated by air, water and/or nitrogen. Fumes which develop during heating, evacuation of fluid from the pores, baking and cooling are filtered to avoid contamination of the surrounding area.

Abstract: The invention relates to a composition and a process for the treatment, more precisely the "post-treatment" of phosphatized metal surfaces, particularly when the surfaces must be subsequently covered with a coat of paint. It relates also to a process for the preparation of the composition and a concentrate useful for this preparation. The composition comprises an effective proportion of trivalent titanium compound and it is presented with an acid pH, the proportion of said compound being sufficient for the corresponding composition to confer on the treated metal surface a protection equivalent to that obtained with known chromatizing solutions. More particularly, the composition contains trivalent titanium at a concentration of 0.01 to 2 g/l, preferably from 0.2 to 0.6 g/l and has a pH of 2 to 7. Reducing means can be arranged to regenerate the trivalent titanium in the treatment solution continuously.
