Abstract: SCREW CONVEYOR IN PULP-MAKING EQUIPMENT               ABSTRACT OF THE DISCLOSURE      A screw conveyor which is particularly used for feeding in and compressing ligno-cellulosic material, such as wood chips, shavings, bagasse, sawdust and similar compressable material. The screw conveyor comprises a casing having a bore which tapers conically from a material inlet and to a material outlet end.  A screw feeder having helical flights and an intervening spiral groove rotates within the bore to advance the material fed into the casing towards the outlet end while being progressively com-pressed into a plug.  The casing has an opening in which stopper means move in a closed circuit to successively engage the spiral groove during the rotation of the screw feeder, thereby preventing the material from rotating and thus allowing it to be continually advanced while being progressively compressed.

Abstract: FLASH-TUBE IGNITION SYSTEM WITH MEANS FOR VARYING THE COMBUSTIBLE   MIXTURE WITHIN THE FLASH-TUBE     Abstract of the Disclosure A combustible fuel gas burner has a primary tube supplying gas and primary air to a main burner, a secondary tube supplying secondary air to the main burner to afford complete combustion, and an exhaust tube through which the products of combustion are exhausted.  The exhaust tube also acts as a flash-tube for igniting the main burner.  In the absence of combustion, the gas and primary air issuing from the primary tube and the secondary air issuing from the secondary tube combine to form an air-gas mixture in the exhaust tube which is too lean (below the lower limit of flammability) to be ignitable.  The supply of secondary air is controlled so as to vary the air-gas ratio in the exhaust tube such that this ratio changes through a spectrum of values between the lower and upper limits of flammability wherein the flame propagation speed of the mixture is substantially greater than the flow velocity thereof.  A resistance coil is provided at the outlet of the exhaust tube and is energized at an optimum value of the changing ratio, corresponding to an explosive mixture, whereby a flame travels or flashes back to the main burner.

Abstract: ABSTRACT:            A multi-channel X-ray detector for use in a device for computer tomography in which an object to be examined is irradiated from different directions by means of a flat, fan-shaped X-ray beam. The locally transmitted radiation is measured and the density distribution of the object is calculated on the basis of the measuring data. The X-ray beam and the X-ray detector together rotate around the object during the examination. The X-ray detector comprises  a number of plate-shaped, at least substantially parallel arranged electrodes which are mounted on a supporting plate and which are accommodated in a gastight housing. In order to prevent influencing of the output signals of the detector by vibrations of the equipment, the supporting plates are made of a material which strongly damps vibrations.

Abstract: ABSTRACT A method and apparatus for separating poultry meat from bone are disclosed, in which separation is accomplished through the use of centrif-ugal force.  A poultry section is attached to a rotating member, and the high-speed rotation of said member, with controlled acceleration, causes the desired separation of meat from bone.  The method taught is a dry method, and produces large chunks of meat, neatly and conveniently separated from the bone by centrifugal forces alone.  Also disclosed is an apparatus which separates meat from bone of a plurality of carcasses in semi-automatic fash-ion.  Poultry pieces, continuously attached to the apparatus by hand, are then automatically deboned by centrifugal force, and the meat recovered.

Abstract: Contacteur limiteur présentant l'avantage que l'ouverture des contacts lors de l'apparition de surintensités dans le circuit est suffisamment rapide pour lui conférer les propriétés de limitation de courant qui sont aujourd'hui nécessaires même dans les appareils dont le courant nominal est relativement faible. La constance de seuil de déclenchement lors du vieillissement de l'appareil est en outre assurée. Ces résultats sont atteints grâce au fait que le contact mobile est un pont de contact symétrique associé à un premier organe de rappel élastique placé dans l'axe de symétrie et qui tend à l'appliquer sur deux contacts fixes, que le noyau associé au bobinage transmet son mouvement au pont de contact concentriquement audit axe entre l'armature de l'électro-aimant et le pont de contact, que le percuteur effectue une course telle que la position donnée au pont de contact lorsque le noyau est maintenu par les moyens d'accrochage soit suffisante pour provoquer la limitation du courant, et qu'une tige de poussée transmettant les mouvements de ladite armature audit pont de contact, sans être reliée à ce dernier, se déplace dans ledit axe de symétrie, des seconds organes élastiques de rappel agissant sur l'armature pour provoquer la séparation du pont de contact des contacts fixes lorsque l'électroaimant n'est pas alimenté.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a miniature transducer which is particularly suitable for use in opthalmic measurements and more specifically in the measurement of intra-ocular pressure in vivo.  To this end, the miniature pressure transducer of the present invention comprises a container having a concave surface for fitting on the eyeball of a patient and a central aperture is formed in the concave surface through which one end of a permeable core extends.  A first coil is fixed to the other end of the core interiorly of the container and a second coil is fixed to the container between the concave surface and the first coil.  Resilient means normally urges the first coil and core to a rest position whereat the first and second coils abut one another and the first end of the core projects through the aperture to be acted upon by pressure in the eyeball with which the transducer is associated.      Thus, the core and the first coil are moved by pressure of the eyeball such that the resonant frequency of the coils is changed in a manner directly proportional to the intra-ocular pressure.  In use, it is not necessary for any external connections to be made to the transducer and it is merely necessary to bring a device such as a grid dip oscillator into proximity with the transducer for coupling with the resonant frequency of the coils in the container.      Accordingly, the device of the invention is exceptionally simple in construction and reliable in operation and does not require any external connections or fittings for use to make measurements of the intra-ocular pressure of the eyeball.  On the other hand, devices of the prior art require external fittings with resultant problems to the wearer.

Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for the automatic filling of plastic bags with, for example, elastic,soft and deformable contents.  In order to provide for the automatic handling of empty bags without intermediate, especially manual,steps, the invention provides that the empty bags are attached by extending flaps to a plastic carrier web across a tear line.          The apparatus of the invention places a quantity of goods into the bag by means of an axially moving filling piston which passes between spreadable jaws that hold the bag open.          The continued motion of the filling piston eventually exerts a force sufficient to cause fracture along the tear line and separation of the filled bag from the flap which stays attached to the carrier web.  The piston then moves the filled bag into position for sealing.  A number of embodiments is presented.
