Abstract: The diameter of the supporting-tube of the preform (TQ) can be kept constant by this method, notwithstanding the tube tendency to collapse owing to the high-temperature necessary to reactant synthesis reaction and raw-material deposition. 
     The diameter is controlled by generating between the internal and the external tube surface a pressure difference variable in a way inversely proportional to the diameter of the tube itself and to the total gas flow at the input. 
     The device (GP) allows the generation of the required pressure loss at the output and the separation of raw-material solid particles from residual gases (Fig. 1).

Abstract: Improvement in the catalytic dehydrohalogenation of a halogenated hydrocarbon to an ethylenically unsaturated product with aqueous alkali in a series of reactors in a cascade arrangement, wherein the fresh alkali feed is relocated from the first reactor to a reactor subsequent to the first, and partly spent alkali solution from the last reactor is recirculated to the first reactor, while the ethylenically unsaturated product is recovered from the effluent from the last reactor, and waste brine is removed from the effluent from the reactor immediately preceding that to which fresh alkali is fed. In this manner, the amount of both the alkali and the catalyst can be reduced, and the conversion is increased. Dehydrochlorination of 3,4-dichlorobutene-1 gives chloroprene, which is a valuable monomer for making synthetic elastomers.

Abstract: In focusing the laser beam (3), use is made of so-called "speckling", which is observed as a more or less coarse-grained spatial distribution of intensity of the light (4) backscattered from the illuminated spot. The scattered light (4) is observed for this purpose visually or, preferably, by photoelectric means (7, 8, 9), and the focusing is varied until the granulation of the scattered light is coarsest and in this way the best focusing condition is found. Focusing can be done by hand or automatically in a closed control circuit. The method is simple, requires no extraneous light, and is insensitive and non-critical with regard to adjustment. <IMAGE>

Date Jul. 5, 1984.The method for measuring strains in a part uses the reflection of an acoustic wave, while measuring a transit time of said wave by means of an apparatus which measures the fade-in time of an echo coming from an interface. The method comprises the steps of selecting within the medium one or a plurality of ends of rectilinear measuring runs, which ends are embodied by an inner artificial reflector (8, 9) emitting of a beam of acoustic waves so that acoustic rays carrying sufficient energy strike the useful reflectors, selecting the echoes corresponding to the reflectors, determining by measurement the transit times which are characteristic of the useful acoustic rays up to the inner artificial reflectors and transposing the transit times for each inner reflector considered individually or the respective differences of transit times for each couple of reflectors into an outer strain value or into a strain value within the region delimited by each couple of reflectors. The part for implementing such method comprises reflectors consisting particularly of perforations or bores into the part.

Abstract: Dans la plupart des copieurs électrographiques utilisant un développement à brosse magnétique (14), le rouleau applicateur de la brosse (26) est disposé dans une position fixe par rapport à la surface de l'organe isolant (12) de sorte que le poil de la brosse du matériau de développement est toujours maintenu en contact avec la surface. A certaines occasions toutefois, il est désirable de pouvoir empêcher de manière sélective le contact entre le poil de la brosse et la surface. Jusqu'à présent on a utilisé uniquement des techniques mécaniques pour commander de manière sélective l'application du matériau de développement par les brosses magnétiques. Malheureusement, ces techniques compliquent la construction de la brosse magnétique (14) et présentent un temps de réponse relativement lent dans l'établissement et la suppression sélectifs du poil de la brosse convenant au développement des motifs de charge. Cette réponse lente limite la vitesse opérationnelle du dispositif de reproduction. Afin de résoudre ce problème, la brosse magnétique (14) du dispositif ci-décrit utilise un ou plusieurs électro-aimants (32) qui, lorsqu'ils sont mis sous et hors tension, respectivement établissent et suppriment une surface de poil de développement entre la brosse et un motif de charge développable.

Abstract: In the soilless cultivation of plants, in which the latter are held floating on the surface of a body of water and with their roots (13) immersed in the water (1), the water in contact with the roots of the stationarily retained plants is constantly exchanged and, in particular, guided past the roots in a horizontal flow. In this manner, the growth disorders caused by depletion or concentration of the nutrients, minerals, etc., dissolved or dispersed in the water are avoided. A floatable, stationarily anchored lattice structure (3), to which the plants (12) can be fastened, serves to retain the plants relative to the water. In this structure the mesh width may be adjustable in order, for example, to increase the distance between the plants with increasing growth of the latter. <IMAGE>
