Patent AT-E71215-T1 (AT)

Abstract: The inefficiency of the nitrogen stripping section of a high purity oxygen-producing air distillation plant is reduced. This allows increased recovery of byproduct argon and in some cases increased recovery of refrigeration work also. The improvement is obtained by evaporating kettle liquid with condensing argon rectifier vapor in two sequential stages, to yield vapor streams respectively having more and less O2 content than the kettle liquid, and separately feeding them to the N2 removal column. The improvement is applicable to both dual and triple pressure processes. Referring to FIG. 1, kettle liquid is supplied via valve 11 to the top of contactor 18, and overhead reflux condenser 13 of argon rectifier 14 reboils the bottom of contactor 18. Vapor streams of differing O2 composition are withdrawn from above and below 18.

Abstract: Apparatus for the reproduction of data, which can be read contactlessly from a recording medium by means of an optical pick-up device. 
<??>Such apparatuses are equipped with a focus control circuit, in order to focus the light beam picking up the data onto the recording medium, and with a tracking control circuit, in order to be able to guide the light beam on the data tracks. The light beam is reflected from the recording medium onto a photodetector (PD) comprising a plurality of photodiodes (E, F). Because actual photodiodes (E, F) are not completely identical, they give off different photoelectric voltages under the same illumination. Therefore, the control amplifier (TR) of the tracking control circuit operates unsymmetrically. 
<??>In order to bring the operating point of the control amplifier (TR) of the tracking control circuit into the optimum centre position, an offset-compensation voltage is applied to an input of the control amplifier (TR) and varied until the photoelectric voltages of the photodiodes (E, F) from which the track error signal (TE) is obtained are of equal magnitude.

Abstract: The intermittent straightening of the wire (1) is carried out by means of a fixedly supported straightening rotor (4), the straightening blocks (5, 6, 7) of which radially deflect the wire (1) advanced by conveying mechanism (2). The mass moment of inertia of the straightening rotor (4) is dimensioned to be so small that the straightening rotor (4) can be decelerated and accelerated at least approximately within the same time period as the wire (1) by the conveying mechanism (2). For cutting to length, the straightening rotor (4) is braked in synchronism with the wire (1) and thereafter again accelerated. Thereby, a perfect wire quality is achieved, in particular a uniform elongation approximately constant over the entire length of the wire, without having to move the cutting device at the high wire feeding speed, or without having to move the straightening rotor axially or the straightening blocks radially, in order to avoid heating up and damaging of the arrested wire by the further operating straightening rotor. Different straightening rotors (4) are utilized for different wire types, these rotors being easily exchangeable with their bearings (46).

Abstract: For a thermal transfer dyesheet, a protective backcoat is provided by polymerising acrylic functional groups in a composition comprising: an organic resin comprising at least one polyfunctional material having a plurality of pendant or terminal acrylic groups per molecule available for cross-linking, at least 10% by weight of the polyfunctional material having 4-8 such acrylic groups per molecule; at least one linear organic polymer soluble or partially soluble in the resin, and comprising 1-40% by weight of the resin/polymer mixture; a slip agent selected from derivatives of long chain carboxylic or phosphoric acids, long alkyl chain esters of phosphoric acid, and long alkyl chain acrylates; an antistatic agent soluble in the resin, and a solid particulate antiblocking agent less than 5  mu m in diameter. Resins having predominently 5-7 acrylic functional groups per molecule, are preferred for enhancing protection against the thermal head, especially when used in a mixture also containing molecules having only 2-4 such acrylic groups per molecule. The effect of using such mixtures to cross link molecules of both high and low acrylic functionalities in the presence of the linear polymers, is to enable good thermal protection to be provided by a durable low friction coating, which also cleans the thermal head during printing.

Date Sep. 7, 1988.A control mechanism for an automatic transmission (1) of a motor vehicle including one electronic control unit (2) for determining the shift points for the change of gear. The latter results at least from the information from the vehicle speed (3) and the required load (4). The shift points are overridden by orders issued by the adjusting means needed for operation of the vehicle. A flasher unit (6) known per se for indicating the direction of travel is additionally connected via a line (61) with the electronic control unit (2) and via a flash-unit signal the generally known determination of the shift point is overridden either by an immediate downshift by at least one gear or a control of the downshift and upshift points in the sense of increasing them. The activity of the flash-unit signal can remain limited to the higher gears of an automatic transmission. The signal from the flasher unit (6) also overrides all eventually selected programs (such as economic program) and can also suppress intended upshifts.

Abstract: Flat objects, such as printed sheets, periodicals and newspapers arrive in overlapping formation (6, 6<'>). In order to count the objects continuously, the overlapping formation (6, 6<'>) is moved along a conveyer plane (3) through the active region of an ultrasonic transmitter (7). Two ultrasonic receivers (7<'>, 15) for receiving the echo waves are directed counter to the active region of the conveyor plane (3) in two directions at an angle to one another. The echo signals of the receivers (7<'>, 15) are fed to a data evaluation unit (14) via a control unit (13). The data evaluation unit (14) contains counting and computing means in order to sense the timing and the size of successive echo signals of the receivers (7<'>, 15), to compare them and to process them. As a result, a reliable counting of the individual objects in the overlapping formation (6, 6<'>) is obtained independently of the prevailing illumination and reflection conditions and independently of the state of the overlapping formation (6, 6<'>).

Abstract: A method of isolating genomic or RNA-derived duplex fragments which are unique to one of two fragment mixtures. The fragments in positive-source and negative-source mixtures are separately equipped with end linkers, and each mixture is amplified by successive primed-strand replications, using a single primer which is homologous to the associated linker. The second-source linker is biotinylated, and the fragments in this mixture are hybridized in molar excess with the fragments in the positive-source mixture. DNA species which are not hybridized with the biotinylated species, i.e., species that are unique to the positive-source mixture, are isolated after removal of hybridized species by affinity chromatography. Also disclosed is a method of amplifying a mixture of DNA fragments by repeated linker/primer replication.
