Abstract: 1. Process for the esterification of acetic acid with C2 -C5 -alcohols in the presence of an acid catalyst, wherein the esterification is carried out in a vertical reactor in conjunction with a distillation column into which the reaction mixture leaving the reactor is introduced, the ester formed, and the water, being taken off as an azeotropic mixture via the top of the column and the azeotropic mixture being separated, if appropriate, into an organic phase and an aqueous phase, characterised in that the catalyst used is a strongly acidic ion exchanger and that the reflux ratio of the azeotropic mixture is set to 0.5-20 or the reflux ratio of the organic phase is set to 0-20, based on the amount of ester formed, and the reflux ratio of the aqueous phase is set to 0-20, based on the amount of water formed, and that the unconverted acetic acid and the unconverted C2 -C5 -alcohol are continuously taken off, as vapour, from the bottom and are reintroduced into the esterification reactor together with supplementary amounts of acetic acid and of C2 -C5 -alcohol corresponding to the amount of ester taken off at the top.

Abstract: Reine tert.-Olefine werden aus Kohlenwasserstoff-Gemischen, die mindestens ein solches tert.-Olefin enthalten, durch Umsetzung mit einem Alkanol zu den zugehörigen Alkyl-tert.-Alkylethern und anschließender Rückspaltung dieser Ether in die zugehörigen reinen tert.-Olefine und das Alkanol und Abtrennung der reinen tert.-Olefine vom Alkanol hergestellt. Hierbei wird das nach Rückspaltung des Ethers anfallende Alkanol zu 60 bis 99 Gew.-% destillativ vom tert.-Olefin abgetrennt und die restliche, in die OlefinFraktion gelangte Alkanolmenge durch Absorption aus dieser Fraktion an einem synthetischen Ionenaustauscher als Absorberharz entfernt. Die Zumischung des Alkanols zu dem Kohlenwasserstoff-Gemisch mit mindestens einem tert.-Olefin geschieht teilweise durch Verwendung der bei der Abtrennung des reinen tert.-Olefins anfallenden Alkanol-Fraktion und teilweise durch Desorption des Alkanols vom Adsorberharz mit Hilfe des mindestens 1 tert.-Olefin enthaltenden Kohlenwasserstoff-Gemischs.

Abstract: To control goods turnover, goods and material movements and goods values, these are provided on delivery with identifications to which the necessary data have previously been applied, for example with the aid of the recorder (printer) belonging to a data processing system. The identifications or control cards are read and analysed by machine when they are leaving or being sold or on other occasions such as, for example, stock taking. For this purpose, identifications with separable control cards are preferably used which are separated, isolated and then read at each intermediate station. For this purpose, a device is provided in which the control cards are collected and are then individually passed below a read unit and read. To protect the individual control cards and to facilitate filing, cassettes for accommodating or for catching (stacking) the individual control cards are provided in the hopper and at the end of the housing. Misreadings are avoided by allocating the signal transmitters to the read head and a stopper consisting of separating section and release. This stopper pushes a separating section between the separator and the last card so that the latter can no longer be moved out. <IMAGE>

Abstract: The formwork system for high buildings, which combines the static values of monolithic concrete walls with high thermal and acoustic insulating values and economic advantages, consists of rigid-foam mantle boards (f) which are braced not from the outside inwards at certain points throughout, but indirectly, over a large area in terms of formwork, via prestressed spring plate elements (a, d). As a result, sufficient resistance is offered to the concrete contact pressure. Heat/cold bridges are prevented due to the rigid-foam mantle formwork extending over the steel-wire prestressing hooks (d). Two dimensionally matching rigid-foam mantle boards (f) and one prestressed spring plate element (a, d) are in each case fitted together, for transportation, to form a compact unit in such a way that damage to the rigid-foam mantle boards (f) is prevented. <IMAGE>

Abstract: @ A paper shear mechanism consists of a guillotine (8) having a fixed blade (19) and a pivoted blade (21). The cutting edge (20) of the fixed blade is concavely curved so that paper (4) to be cut fed between the blades assumes a corresponding curvature and is given some longitudinal rigidity during the cutting operation. The pivoted blade is of composite structure to simplify the manufacturing process and thus reduce cost. Essentially, it includes a cutting section (37) stamped from flexible sheet steel shim to provide a cutting edge (40) with the desired nip angle. The flexible steel section is spot welded to a mild steel backing member (39) with an elongated spring member sandwiched between the two. The spring member has a number of spring teeth (41) which exert a force along the length of the flexible section to deflect its cutting edge laterally towards the fixed blade. By this means contact between the cutting edges (20 and 40) is maintained along the length of a cut and relief between the facing surfaces of the two blades is provided. A sheet feeding apparatus with a correspondingly curved cross-section to the fixed blade feeds paper web (4) to the shear mechanism. A single motor (13) serves to feed paper during forward rotation and to operate the paper shear during reverse rotation.
