Abstract: ABSTRACT     A process for converting a thallium(I) compound to a thallium(III) compound suitable for use in oxythallation of unsaturated organic compounds such as olefin, acetelynic and carboxyl compounds by contacting a gas containing oxygen at a partial pressure of at least 10 kPa with a reaction medium at pH 9.6 or greater and containing a thallium(I) compound and a peroxygen compound in an amount equivalent to oxidize at least 1% of the thallium(I) to thallium(III).  The process provides an economical method to oxidize thallium(I) to thal-lium(III) with oxygen at a lower pressure than that described in the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE      There is provided a hydrocarbon extraction process and apparatus for removing hydrocarbons from a hydrocarbon containing ore such as a diatomite ore.  The ore is pre-processed to the extent required to produce an extractable ore and subsequently mixed with a carrier to form an ore stream.  The carrier may be a nonaqueous solvent and may further comprise a non-porous granular material such as sand.  The ore stream is passed in substantially vertical countercurrent flow through a nonaqueous solvent to produce a product-solvent stream and a spent ore stream. The solvent is subsequently separated from the hydrocarbon stream, which may be further upgraded by removal of a heavy portion.  This may be accomplished in the presence of a substantial amount of fines.

Abstract: ABSTRACT A labeling machine for objects such as bottles has a labeling station with a glue roller (1) that has an elastic glue roller covering.  A glue scraper (4) defines with the glue roller surface a gap that is adjustable in order to regulate the thickness of the glue coating. Adjustment of the glue scraper (4) takes place as a function of the machine output in such a way that at higher machine outputs the gap is reduced and at lower machine outputs the gap is increased.  This adjustment of the glue scraper (4) as a function of the machine output compensates for the flattening of the glue roller (1) that occurs as a result of the glue pressure.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a structure of neutral point of multiphase transformers for large secondary currents. Such multiple phase transformers, usually three phase transformers, are used for example for the operation of arc furnaces, and the secondary current of the transformer may amount to several thousand ampere. The neutral point is made as a plate (24) of material with good electric conductivity and is located within the transformer tank (27). Between the neutral point plate (24) and the tank wall (27) there is located a plate (25) of a material with good conductivity and serving as a screen for reducing losses in the tank wall (screen plate). The transformer is star connected on the secondary side. Each phase of the secondary winding consists of several windings connected in parallel, and the tappings are passed as parallel conductors onto the neutral point plate (24). The neutral point tappings (22) are connected to the neutral point plates (24), whereas the phase tappings are passed through openings both in the neutral point plate (24) and the screen plate (25) onto insulating ducts (26) in the tank wall (27).

Abstract: Abstract For indicating a pressure decrease in a pneumatic tyre a valve cap which is threadable onto the tyre valve is used. The sleeve thereof, which is threadable onto the valve tube, comprises an actuating member which is capable of opening the valve mounted in the valve tube when the sleeve is in the threaded-on (operative) posi-tion. Furthermore, a compressed-air chamber is provided, which communicates with the interior of the tyre through the open valve and is sealed by a movable diaphragm or a piston, said diaphragm or piston actuating an axially displaceable indicator biased by a spring towards the actuating member and moving a marking member into its initial position when pressure is applied to the com-pressed-air chamber. Upon a pressure decrease in the compressed-air chamber, the indicator follows the re-sultant displacement of the diaphragm or piston, re-spectively, while a return movement inhibitor retains the marking member in its initial position. The re-sultant variation of the relative axial distance of both members is used to indicate a pressure decrease. The end of the sleeve which is remote from the valve may her-metically be sealed by a hat-shaped cover of a trans-parent material permitting extension of the indicator and the marking member.

Abstract: GRINDING MACHINE FOR WET GRINDING   FLAT ROLLS WITH WEAK PROFILES     ABSTRACT        The invention concerns a grinding machine for wet grinding the rolls of flat rolling works.  The grinding machine contains an especially accurate measuring device for measuring diameter changes, which measures the diameter change of the roll in a non-contacting manner during the grinding process at exactly the area being ground.  This takes place with the help of a holder having an air jet fixed to it.  The air jet has a spacing of about 0.2 mm to the surface of the roll.  As soon as this spacing is slightly changed the changed pressure head works on a piston which operates to return the spacing to the desired value.          In addition to the length measuring device for measuring the changes in roll diameter, the holder also has on it other measur-ing devices, such as the probe of a crack inspecting apparatus.

Abstract: METHOD OF INHIBITING PROCESSING OF DUPLICATIVE                CODED LABEL SIGNALS                           Abstract A system is disclosed for preventing processing of duplicative coded label signals generated by a scanner lacking item detectors.  The system establishes a variable lockout time as a function of operator performance.  Any detected label candidate which duplicates a candidate received within the lockout time is assumed to be duplicative.  Any transfer to the terminal is inhibited. Operator performance is tracked by measuring the inter-item arrival times for candidates actually transferred to the terminal.  The inter-item arrival times are averaged over a given number of items.  The average value is used to select a lockout time which is generally proportional to the average inter-item arrival time.
