Abstract: L'élément de report d'images décrit, qui est constitué par exemple par un tambour de report d'images (18), utilise une dépression appliquée par l'intermédiaire d'ouvertures d'application de dépression (19) sur la surface du tambour, afin de maintenir en place une feuille réceptrice. Le report sur la feuille d'une image colorée par toner s'effectue par activation d'un champ électrique. Les ouvertures d'application de dépression sont conçues suffisamment petites pour empêcher la création de défauts de report visibles causés par l'absence de report du colorant toner à proximité de l'ouverture, mais suffisamment grandes pour maintenir la dépression contribuant à l'application de la force de retenue sur la feuille. Selon un mode de réalisation préféré, de larges trous d'application de dépression sont ménagés dans le tambour et une pièce rapportée conductrice (70; 80; 90; 100) définissant ou contribuant à définir de petites ouvertures d'application de dépression est introduite dans chaque trou d'application de dépression. La pièce rapportée assure la continuité du champ électrique dans la région des trous, alors que sa géométrie permet aux petites ouvertures de maintenir l'application de la dépression. Cette invention est particulièrement utile pour des appareils de report d'images, dans lesquels le report de plus d'une image colorée par toner est effectué dans l'alignement de la feuille réceptrice.

Abstract: An improved method and apparatus for the safe handling of alkylation catalyst. The method and apparatus comprises a process vessel which serves a dual function of storing alkylation catalyst and of recontacting alkylation hydrocarbon product with alkylation catalyst. Alkylate product is passed through an eductor-mixer device which intimately mixes alkylate with catalyst. This mixture flows into the dual function recontacting vessel where a phase separation of the catalyst and alkylation hydrocarbon product takes place. Conduits are provided to connect the process reactor, cooling heat exchanger, settler, and interconnecting piping so as to allow the quick release of pressure from the combination storage-recontacting vessel and subsequent draining of catalyst into the vessel by use of gravitational force. The method and apparatus consists of a physical arrangement and use of alkylation process equipment in a manner which allows the use of a single vessel for both storage of alkylation catalyst and recontacting of alkylation hydrocarbon product. The apparatus and method is a safety feature which allows the transfer by draining of catalyst from the alkylation process vessels into the storage vessel by the sole use of gravitational energy motive force.

Abstract: A process for the preparation of optically active amino acid amide whereby a mixture of the L-amino and D-amino acid amides in the presence of 0.5-4 equivalents of an aldehyde, relative to the quantity of amino acid amide, in the presence of a solvent and water, is converted in whole or in part by means of an optically active carboxylic acid into a salt of the amino acid amide and the carboxylic acid, and a portion mainly consisting of one of the diastereoisomers of that salt is separated from the reaction mixture obtained. Instead of a mixture of L-amino and D-amino acid amides it is also possible to use a mixture of the Schiff bases of an amino acid amide and an aldehyde, in which case it is not necessary to add extra aldehyde, and the required quantity of water amounts to at least 1 equivalent relative to the quantity of Schiff base. With this process a high yield of optically active amino acid or the corresponding amino acid is rapidly obtained.

Abstract: Cette invention concerne une structure d'emballage d'aiguille comprenant un joint annulaire (1) réalisé dans un matériau plastique à masse molaire extrêmement élevée, tel que du polyéthylène. Un passage concentrique à réduction (4) traverse le joint avec un épaulement (6). L'extrémité externe de la paroi interne du passage possède une lèvre d'étanchéité (7) formée par un angle à 15° avec la paroi interne. La lèvre est en prise avec une aiguille (8) appartenant à une soupape empêchant l'entrée d'un fluide au-delà du joint. La structure comprend également une doublure (9) réalisée dans un matériau plastique approprié comme du P.T.F.E. permettant d'obtenir un joint coulissant avec l'aiguille (8).

Abstract: In a sound reproduction system (3) for sound reproduction with spatial sound effect at a specific hearing location (10) in a room limited on all sides, in particular the passenger compartment (2) of a motor car (1), loudspeakers (11, 12, 21, 22) are disposed in this compartment in such a way that they generate a spatial sound. To ensure that this spatial sound effect is positioned at a specific hearing location (10), a specific delay time is provided as a basic setting on sound signal delay devices (13, 14, 23, 24) in the loudspeaker channels (17, 18, 27, 28). A considerable fluctuation range exists for the basic setting, within which a change in the spatial sound effect cannot be heard at the hearing location. In addition, this fluctuation range is exploited in order to set the delay times within the fluctuation range in such a way that a smoothing of the frequency response of the sound level at the hearing location is also achieved. <IMAGE>

Abstract: A rotary displacement measuring apparatus includes an axle whose rotary displacement is to be determined, with the axle being mounted to rotate about its long axis. An emitter is mounted on the axle to define a plurality of concentric tracks circumscribing the axle to rotate as the axle rotates, with each of the tracks being segmented to define a plurality of spaced-apart, conductive sections for producing electric fields when energized. Also included is a voltage source for energizing the conductive sections. A detector is disposed adjacent to the tracks of the emitter and includes a plurality of sensors, each positioned adjacent a respective track to detect the electric fields of the respective track as the axle and tracks are rotated. The detector produces signals representing the variation in the electric fields as the emitter is rotated, and these signals provide an indication of the rotary displacement of the tracks and thus of the axle. <IMAGE>

The chisel (10) has at least one coupling groove (12) at its shank end (11) facing the tool and a chisel edge (14) at its other end (13), which chisel edge (14) is U-shaped in cross-section and has at least one laterally projecting, fin-like sliding-surface element (18-23) which is supported on a surface of the construction and in the process guides the chisel edge (14) at a certain setting angle ( alpha ,  beta ) to the surface of the construction. The object of the invention is to provide a chisel (10) of the generic category mentioned at the beginning which on the one hand ensures the known slot-depth limit and on the other hand permits different slot depths in accordance with a wide range of variation of the setting angle ( alpha ). This object is achieved according to the invention in that several sliding-surface elements (18-23) with different setting angles ( alpha ,  beta ) relative to the longitudinal centre axis (24) are arranged in the adjacent area of the chisel edge (14), of which sliding-surface elements (18-23) the sliding-surface element (20, 22) with the largest setting angle ( alpha ) is allocated nearest to the chisel edge (14) and is either arranged directly next to the chisel edge (14) or is set back relative to the latter. <IMAGE>

A very high percentage of granulate sizes corresponding to the size of the desired final product can be produced directly with the new process in particular for further processing of the small lumps to form couscous. The individual small lumps have a complete protein structure when leaving the whirl kneader. For large throughput capacities, the whirl kneader is constructed as a double-rotor kneader. It is important that the minimum kneading time does not fall below at least 5 to 10 seconds and it would be more advantageous not to exceed a maximum kneading time of 2 to 3 minutes.
