Abstract: APPARATUS AND METHOD FOR FACSIMILE SCANNING     ABSTRACT            A selector disc defining a single revolution spiral aperture is concentrically rotated with a scanning disc defining four nested multiturn spiral apertures.  An elongated fixed slit is positioned between the discs and as the discs rotate, an exposure aperture is defined by the slit and a selected scanning spiral, the aperture mov-ing linearly across the slit. The drive ratio between the discs is such that their relative positions advance so that adjacent scan lines are defined by alternate scanning spirals. Further, each scanning spiral is composed of a series of contiguous, arcuate segments forming in the gen-eral path of an Archemedian spiral thus providing a scanning system having improved resolutional characteristics.

Abstract: Abstract of the Disclosure There is disclosed a method of obtaining selective impregnation of heterogenous fiber containing material during feeding-in of the fiber material through an impregnation space to a pressure vessel, wherein a mixture of fiber material and transport liquid in an uninterrupted flow is pumped through a feeding line-opening into a liquid filled space in the pressure vessel where transport liquid is separated from the mixture through one or more outlets located higher than the entry point of the feeding line, and wherein particles of the fiber material which do not sink in the liquid but float upwards are permitted to follow the separated transport liquid in recirculation through the impregnation space in order to obtain prolonged impregnation time compared to the fiber particles which sink.  An apparatus for carrying out the method is also disclosed.  The method leads to a more even impregnation of hetero-geneous fiber material.

Abstract: ABSTRACT OF THE DISCLOSURE          A record sleeve for a phonograph record is formed by folding a paper or other flexible web along a transverse fold line so to provide top and bottom panels which are bond-ed together by elongated beads of adhesive material previous-ly applied to one surface of the web generally along two opposed side edges thereof but slightly inwardly of those edges.  Before folding, information is usually printed on the outer surface of the web and, after the two panels have been bonded together by the adhesive material, they are trimmed outwardly of the adhesive to eliminate printing bleed.  The reduced thickness of the outwardly extending bonded seams permits a less loose fit of the sleeve containing a record in a conventional outer jacket.

Abstract: Abstract of the Disclosure The disclosure relates to a manually operable atomizer in which a liquid is drawn in and pressurized by an atomizer means and is then atomized through a nozzle.  A chamber for pressurizing the liquid is constituted by a cylinder, while an atomizer head is connected to a communication pipe which plays also the role of a piston, and is biased in the direction reverse to the pressurizing direction, by means of a spring.  The atomizer head is provided with a guiding member adapted to be pressed and moved by an inclined surface of an actuating member, so that the atomizer head and the piston or the pipe are moved in the pressurizing direction.  As the actuating member is released, the spring moves the member back to its original position.  Portions of the periphery of the atomizer head other than the nozzle and the operating portion of the actuating member are covered by a cap.  The actuating member moves in a direction transverse to the direction of movement of the atomizer.

Abstract: ABSTRACT OF THE DISCLOSURE A test device for determining a characteristic of a sample, particularly for determining substances in fluid samples. The device comprises a strip element which is composed of a material capable of transporting a developing fluid therealong by capillarity and which has a portion at a predetermined location on the strip element for receiving the test sample and portions at predetermined locations on the strip element incorporated with reagent means for providing a detectable response sensitive to the characteristic under determination. The beginning end portion of the strip element is immersed in the developing fluid which, as a result, traverses the length of the strip element, thereby promoting appropriate contact between the test sample and the reagent means resulting in the disposition of a detectable response at a predetermined location on the strip element, which response is a function of the characteristic under determination. The test device is particularly suited for performing binding assays, in particular those wherein a radioisotope is used as a label, such as radioimmunoassays.

Les particules de matières plastiques contenant un agent de gonflement, mélangées avec un liquide polaire, sont introduites en continu dans la cavité résonnante où le liquide polaire est vaporisé sur les particules, provoquant leur expansion, leur séchage étant réalisé par introduction d'air chaud pulsé.  Le procédé et l'installation conformes à l'invention, se distinguent de l'Art antérieur en ce qu'ils permettent d'obtenir des particules de matières plastiques préexpansées totalement exemptes d'eau, séchées au cours même de l'operation de préexpansion et suppriment ainsi la nécessité d'un processus de séchage consécutif à l'opération de préexpansion.  Le procédé et l'installation conformes à l'invention permettent de réduire la durée du traitement et son prix de revient, et de réaliser le traitement de préexpansion en continu, et permettent en outre, une réduction considérable du temps de murissement des particules expansées, avant l'opération de moulage, et l'obtention d'objets en matières plastiques expansées d'une finition parfaite.
