Title: Prepn of acetylene by partial oxidation of - hydrocarbons at normal pressure
Inventor: WOLF-DIETER MUELLER DIPL-ING
IPC: C07C2/78
Filed: 1968-12-05
Abstract: The oxidation product is quenched, compressed to 5-20 atm. and acetylene separated from the compressed gases. The lean gas remaining or part of it is treated to adjust the ratio H2 : (CO+CO2) to 3.1 : 1 to 4.1 : 1, the gases are methanised and the methane-rich gases obtained are recycled to the partial oxidation stage. The H2 : (CO+CO2) ratio may be adjusted by converting part of the CO with water vapour to H2 and CO2 or scrubbing to remove CO2. Any lean gas not methanised may be burnt to provide heat.

Title: Removal of benzene from polybutadiene to give a non
Inventor: JOSEF MARCUSE DIPL-ING
IPC: B01J2/06
Filed: 1968-12-05
Abstract: Chemical or physical treatment of a liquid e.g. carrying out catalytic or non-catalytic reactions, removal of a component from a mixture of liquids or a solution of a solid in a liquid or the like, and more especially for driving off the diluent or solvent from a solution of a material to convert it to the solid state where this includes elastomeric solids e.g. expelling benzene from polybutadiene prepared by the polymerisation of butadiene in benzene, in which the liquid to be treated is introduced as a sub-divided stream into an unconfined stream of a second liquid with which it is caused to undergo the specified treatment eg chemical reaction, heating etc. The removal of solvent from high viscous materials such as elastomeric polymers is extremely difficult, and the usual processes lead to sticky products very troublesome to handle. This process gives dry, non-adhesive particles of polybutadiene which can be used direcly without difficulty. The process can be adapted for a wide range of treatment.

Title: Phthalic anhydride - by catalytic air-oxidn of ortho-xylene
Inventor: FRIEDRICHSEN WILHELM DR
IPC: C07C51/265
Filed: 1972-03-17
Abstract: Phthalic anhydride is continuously mfrd. by air-oxidn. of o-xylene in presence of a supported catalyst which is firmly arranged in the tubes of a reactor comprising a bundle of tubes, the tubes being surrounded by a salt-bath, and the catalyst consisting of an inert carrier and a catalytically active compsn. applied thereon and contg. 99-85 wt.% TiO2 and/or ZrO2, 1-15% V2O5 and 0.1-0.5, pref. 0.2-0.5% P, the supported catalyst contg. up to 3 wt.% V2O5. The salt bath is initially adjusted to 375-410 degrees C; at least 1000 l air and at least 33g o-xylene/Nm3 air air passed through each tube so that a hot-spot temp. of 450-465 degrees C is obtd. in the first one-third of the catalyst layer. After at least 1/2h. the throughput of air (and opt. of o-xylene) is increased without exceeding the hot spot temp. of 465 degrees C; finally the hourly throughput of air is set at 5000-8500 l air and 40-60 g o-xylene/Nm3 air and the hot-spot temp. adjusted to 540-480 degrees C with the aid of the salt bath. Steady control of the hot-spot temp. both prolongs the service life of the catalyst (by avoiding too high temp.) and eliminates risk of interruption of the reaction (by undesired drop of temp. below 500 degrees C).

Title: Oil barrier - for oil slicks on water, with stiffening spacers between the floats for the fabric segments
Inventor: ERLANDSSON EVERT LENNART
IPC: E02B15/04
Filed: 1972-04-27
Abstract: In a multi-segment oil-barrier of the known type having a series of floats, a screen provided with ballast weights and a towing and anchoring cable installed below the floats, the screens consisting of oil-impervious fabric, while the equally spaced floats are produced from solid material of low density compared to water e.g. cellular plastic, the improvement whereby fabric sheathed, preferably resilient, spacers are provided between the floats and keep the screen taut between the individual floats. Meets to a large extent the two contradictory requirements of an oil barrier namely (a) it must be easily handled and able to be conveniently folded up on land or on board ship, for which the floats mut have a maximum spacing, and (b) the parts between the floats must be stiff enough not to tilt too much as a result of wave motion and so become ineffective, for which the floats should be as close as possible.

Patent DE-2315433-A1 (DE)
Title: Measuring bar lengths in continuous casting - measuring roll heated to constant temp gives consistent signal to cut-off device
Inventor: THOMMA GUENTER
IPC: B22D11/16
Filed: 1973-03-28
Abstract: A heated, temp-controlled measuring roll measures bar-lengths on continuous casting plant, thus avoiding discrepancies in length due to temp. variation of the roll and eliminating problems arising in using coolant to keep the roll at a constant temp. A hollow roll, with a hole on one side, is mounted in bearings on a slide so that it rotates as the cast bar moves past. A gas-burner enters through the side-hole and is set so that the flame impinges on the inner wall of the roll. On the periphery of the measuring roll, 180 degrees away from the cast bar is a sensing roll mounted in a shaft which incorporates a control cam. Once the measuring roll reaches the desired temp. its expansion or contraction alters the posn. of the control cam which drives magnetic valves governing the amt. and compsn. of the gas fed to the burner. The measuring roll can thus be maintained at a predetermined temp. thereby giving consistent signals to the bar cut-off device so that uniform bar-lengths are obtd.

Title: Tape-measure of cold-rolled stainless steel - with dark oxide scale-lines on etched background to give high contrast
Inventor: BESTSCHASTNYJ GRIGORIJ K
IPC: G01B3/10
Filed: 1973-04-13
Abstract: An electric-furnace steel is forged at e.g. 1150 degrees C., hot rolled at e.g. 1100 degrees C hardened by quenching in water and descaled by etching. The blank is cold-rolled with e.g. 82.6% deformation, the edges cut-off, then sec. cold-rolled with e.g. 94% deformation to give a thickness of pref. 0.23-0.28 mm. The strip is then slit to 6-16 mm and heated 5-8 hrs. in air at e.g. 425 degrees C to give a dark oxide layer on the surface. A chemical resistant mask is placed over the scale-lines required and the strip etched. The result, after removing the mask, is a scale of dark lines on a bright background, thus producing an easy-to-read high-strength tape-measure.

Title: Electrical stunning device for humane killing - fires thyristors only within fixed inter electrode resistance band
Inventor: DAHLHAUS RALF
IPC: H05C1/06
Filed: 1973-06-13
Abstract: An electric stunning device for humane killing in abattoir included a thyristor in the circuit for the two stunning electrodes which is controlled by the resistance between the electrodes through a separate pilot circuit. The pilot circuit blocks the thyristor both when the resistance is too high and when it is too low; if fires the thyristor only within a predetermined resistance band. This prevents damage to the equipment if the electrodes are accidentally short-circuited or when the hand of an operator happens to be between them. The system also compensates for fluctuations in the mains supply voltage.
