Abstract: Die Oberflächen von Behältern, in denen ultrareine Gase gespeichert werden sollen, müssen im Hinblick auf Reinheit und Passivität gegenüber dem Medium ertreme Anforderungen erfüllen. Dies erfordert den Einsatz von CrNi-Stählen as Behälterwerkstoff. Da diese Materialien nur eine geringe Festigkeit besitzen, sind alle auf herkömmliche Weise hergestellten Druckgasbehälter aus CrNi-Stählen wegen des großen Materialaufwandes sehr teuer und so schwer, daß sich ihr Einsatz as Transportbehälter in den meisten Fällen verbietet. Um leichte, zur Speicherung ultrareiner Gase geeignete Behälter herstellen zu können, wird as Behälterwerkstoff metastabiler CrNi-Stahl verwendet mit definierten Gehalten an Titan, Niob, Nickel und Kohlenstoff. Die gegebenenfalls elektrolytisch polierten Kohbehälter werden durch Aufbringen von Innendruck bei Temperaturen unterhalb der Martensitumwandlungstemperatur in an sich bekannter Weise plastisch verformt und dadurch verfestigt.

Abstract: A cap particularly suited for the airtight sealing of bottles in­cludes two essentially cylindrical bodies (10, 20), the one being inside the other, coaxial and reciprocally sliding. The in­side body presents a series of horizontally mobile elements (15), distributed inside a circular crown, which are connected with holes or with radial slots and which can protrude inwards under the pressure exerted by the action of the outside body (20), when said body is caused to slide downwards. The mobile elements, which can have the shape of balls, stop in this case against the indented lower edge (31) of the bottle neck and insure thereby the tight grip of the cap. In order to obtain the release of the cap it suffices to lightly press the inside body downwards and push the outside body upwards, so as to allow the mobile elements to re-enter their seats. A safety stop of the cap on the bottle is obtained, when the cap is already closed on the bottle, by rotating the outside body.

Abstract: An improved process for the preparation of epoxy resins comprising reacting at least one epihalohydrin with at least one aromatic material containing an active hydrogen atom reactive with an epihalohydrin in the presence of an organic solvent, an alkali metal hydroxide and optionally in the presence of a catlyast for the reaction between the aromatic active hydrogen-containing material and the epihalohydrin while controlling the concentration of water in the reaction mixture. The improvement comprises (1) drying the reaction mixture after completion of the reaction with the concentration of water is equal to or less than 2 percent by weight; (2) removing any insoluble materials from the reaction mixture by any suitable mechanical solid separation means thereby forming a resin/epihalohydrin/organic solvent mixture essentially free of insoluble material; (3) washing the resin/epihalohydrin/organic solvent material with water, so as to remove water soluble materials; (4) drying the resin/epihalohydrin/organic solvent mixture to a water content equal to or less than 2 percent by weight; and (5) recovering the   resultant epoxy resin from the resin/epihalohydrin/organic solvent mixture by an suitable means. The present process maximizes epihlaohydrin yields and also produces epoxy resins low in hydrolyzable halide and total halide.

Abstract: A servo system for flexible magnetic disks such that the synchronization pulses do not have to be perfectly aligned. The disk is encoded such that consecutive servo tracks alternate between having a synchronization and an alternate synchronization mark. Four pulses represent a synchronization mark and two pulses represent an alternate synchronization mark. The alternate synchronization marks are off-set from the synchronization marks by a certain distance, such that they do not interfere with each other when a transducer head located between the servo tracks reads them. The disk drive system will read and identify the synchronization marks or alternate synchronization marks and start generating timing signals as appropriate. The servo bursts in the servo sector can then be read.

Abstract: For running-in a universal roll stand without a trial rolling by means of a trial bar or rapidly to adjust the calibre of a finished stand located directly downstream of a reversing stand group, at least one horizontal roll (1) and the two vertical rolls (3, 4) are provided with hydraulic fine adjustment (16, 17, 20, 21) and an electromechanical coarse adjustment (8-11) to be operated independently. By monitoring all settings by means of travel sensors (12-15; 24-27) and the fine adjustments additionally by pressure sensors and/or rolling-force sensors (28-31), the actual values thereof being reproducible in an electronic control device, it is possible, in conjunction with a travel control of the hydraulic fine adjustments after a coarse electromechanical adjustment, depending on the pass plan, of the vertical rollers (3, 4) and at least one horizontal roller (1), to operate the respective hydraulic fine adjustments under travel control as a function of pressures or rolling forces which are variable as a function of the profile or rolling material. For this purpose, the spring constants of the roll stand, which are used for fixing the set position values, dependent on the pass plan, for the electromechanical coarse adjustments and hydraulic pressures and/or travels, must first be determined by calibration and stored. <IMAGE>

Abstract: 1. Process for preparing boehmite. 
<??>2.1 To date, boehmite for the use in glass, catalyst and ceramics industry has been prepared by digesting ground aluminium trihydroxide in water at elevated temperatures and pressure in the presence of mineral acid. It is now intended to dispense with the initial step of grinding aluminium trihydroxide and the autoclave treatment. 
<??>2.2 The present invention allows a process for converting inexpensive coarse particles of aluminium trihydroxide into finely-particulate boehmite particles, during which process the aluminium hydroxide particles are first heated at a temperature of at least 300 DEG C so as to embed boehmite into a matrix of chi-aluminate. The boehmite product is then separated by dissolving the chi-aluminate, giving boehmite particles of a specific surface area which is greater than that of customary particles of 1 - 2  mu m particle size. 
<??>2.3 The field of application is the preparation of boehmite for the glass, catalyst and ceramics industries.

Abstract: A method for crushing, washing, draining, separating and drying contaminated material, for example plastic, textiles and paper pulp inter alia, consists in the crushing occurring in a stream of water which serves at the same time for washing and conveying. The dewatering can be followed by hot air drying. A device for carrying out this method comprises a container, filled with water, with a filling funnel and submerged pump which conveys the material and cuts it up. The device also comprises a rotatable drum which is fed by the submerged pump at its one end and delivers the cleaned and dewatered material at the other end. The drum and the drying drum are driven by the stream of water conveying the material so that no additional energy is required for this purpose.

Abstract: Electrically conducting homo- and/or copolymers and/or tripolymers can be produced from novel monomers, such as a 3-substituted 2,5-di(2-thienyl)pyrrole. The polymers exhibit unexpectedly high stability and conductivities, and can be functionalized, such as with an enzyme, like glucose oxidase, or an ion-specific binding site, like a crown ether, or an antigen, without adversely affecting the conductivity of the poly­mer. The functionalized, conducting polymer can be used in a diagnostic device to determine the presence and concentration of a specific analyte in a liquid medium. For example, the presence and concentration of glucose is determined by measuring the conductivity change in the polymer caused by the vibrational excitation induced in the enzyme, glucose oxidase, from its reaction with the glucose and/or by measuring a secondary effect of the enzyme/substrate reaction, such as the change in the conductivity of the conducting polymer caused by the generation of hydrogen peroxide during the glucose-glucose oxidase reac­tion.
