Abstract: A processing solution for preventing reflection containing a hydrolyzed derivative of a silicic ester as a major coatforming component and a process for preventing reflection, characterized in that the hydrolyzed derivative of a silicic ester is prepared by conducting hydrolysis of a mixture of the ester with hydrolyzing water in an amount more than a stoichiometrical amount based on the ester in the presence of a solvent miscible with both of the ester and water, and preparing a colloidal solution from the hydrolyzed mixture at a pH of 3 to 7. The processing solution enables formation of a reflection preventing coat with a markedly improved film strength, stain resistance, and adhesiveness to a base by merely heating the coat to temperatures of as low as about 100 °C.

Abstract: The invention relates to a trap for slugs, for the destruction of garden slugs which comprises a tubular housing (1) which possesses a housing opening (2) on one side, extending along the housing. The lower edge of the tubular housing is designed as an oblique surface (4) descending towards the outside, and forms a ramp-like approach surface for the slugs. The upper edge (5) of the housing opening (2) is partly brought over the oblique surface (4) and thus protects the inner compartment of the tubular housing (1) from the penetration of rainwater, which also prevents the slug pellets (8) located within the tubular housing (1) from dissolving and their toxic constituents from being able to penetrate into the soil. Since the trap for slugs is produced from resilient plastic, the tubular housings can be fitted together, if longer sections are needed, and can thus be adapted to any shape of garden or bed. <IMAGE>

Abstract: In venturi coolers for flue gas desulphurisation plants, in which water is sprayed in by means of water spray nozzles (3) through tubes (2) arranged transversely to the longitudinal direction (1) of the cooler, the effectiveness of the sprayed water depends on the velocity of the flue gases not falling below a limit. To increase the flow velocity at low flue gas rates arising, the cross-section has been reduced by means of internals, which are expensive to install, on the wall of the venturi cooler. A simple adjustment of the cross-section of the venturi cooler to the particular flue gas rates arising can be accomplished by means of baffles arranged on the tubes (2), which baffles reduce the flow cross-section of the venturi cooler and leave the outlet of the water spray nozzles (3) free. These baffles can be formed as rotatable cylinders (4), surrounding the tubes (2), with pivotable lugs (5) for rapid adjustment of the cross-section.

Abstract: A dental apparatus is provided which includes a handle (12) having a hollow interior and an end portion (14) which is slightly curved to facilitate insertion in the oral cavity of a dental patient. Within the hollow interior, an air heater system is provided consisting of an air vortex tube (50). Air is delivered to one end (70) of the vortex tube in a direction perpendicular to the longitudinal axis of the tube causing the air to rapidly spin within the tube. The spinning air contacts a deflection member (80) at the opposite end of the tube which causes a portion of the air to deflect rearward toward its point of entry. This air is cool in temperature, and expelled from the rear of the tube. The non-deflected air is warm and directed out of the curved end portion of the handle. The invention further includes an adjustment system (56, 80, 96) to control the temperature of air leaving the vortex tube.

Abstract: Un dispositif à couplage de charge (CCD) est pourvu d'un gradient d'implantation de dopant, de butées de canaux latéraux (12, 14) et d'implants de blocage (16) au moyen d'un faisceau d'ions focalisé (FIB). Le FIB balaye de manière répétée chaque cellule du CCD selon une succession de balayages d'implantation chevauchants mais individuels. Les niveaux de dopage des implantations FIB s'accumulent jusqu'à une approximation en étages d'un profil désiré de densité du dopant, les largeurs des étages n'excédant pas environ la moitié des largeurs des implantations individuelles FIB. Avec un pixel (élément d'image) FIB d'environ 750-1 500 Angstroms, les largeurs des étages sont de préférence d'environ 250-500 Angstroms; la dimension des cellules dans la direction du gradient de dopant peut être inférieure à environ 5 microns. Les butées ou arrêts de canaux latéraux et les implants de rétroblocage peuvent être aussi étroits que des largeurs de pixels FIB uniques, libérant ainsi une plus grande partie de la cellule pour la capacité de transport de charge.

Abstract: For the production of continuously extruded sections (4) from curable synthetic resin, in which reinforcing fibres are embedded over the length of the sections (4), a continuous strand of reinforcing fibres is drawn essentially continuously through a forming device having a die channel (2) and, in the latter, the fibre strand, which is completely impregnated with synthetic resin, is moulded into a section (4) corresponding in its basic cross-section to the basic cross-sectional contour of the die channel (2) and is cured. In this method, before the fibre strand enters the die channel (2), a moulding aid (6), itself continuous, is brought up to the said fibre strand, is passed together with it through the die channel (2) and subsequently removed, leaving behind an additional profiling. A moulding band (6) which has cross-profile regions is used as moulding aid, and the moulding band (6) is laid on the fibre strand ahead of the die channel (2) and, in the die channel (2) is taken out of its basic cross-sectional contour in such a way that the cross-contour line of its outer surface, running outside the cross-profile regions, forms part of the basic cross-sectional contour of the die channel (2). For this purpose, the die channel (2) has at least one longitudinally directed, continuous channel widening (5), adjoining its basic cross-sectional contour, and the die channel (2) is assigned at least one endlessly circulating moulding band (6) having external cross-profile regions, which corresponds in its basic cross-section to the cross-section of the channel widening (5) and is longitudinally guided with its working side (7) in the channel widening (5).
