Abstract: Un système de lentilles à zoom afocal est particulièrement utile dans des systèmes de navigation pour aéronef où l'on désire avoir une puissance de grossissement unitaire (1.0 X). Deux modes de réalisation sont décrits, le premier mode de réalisation utilisant un rapport de grossissement 8:1, le second utilisant un rapport de grossissement 12:1. Les deux modes de réalisation utilisent quatre groupes de lentilles comprenant une lentille frontale d'objectif fixe (A, E), un second groupe de lentilles comprenant un élément de zoom négatif (B, F), un troisième groupe fixe (C, G) et un quatrième élément de zoom négatif arrière (D, H). Dans la position de grossissement la plus élevée, les lentilles sont disposées de sorte que l'élément de zoom frontal est positionné adjacent à la lentille positive du troisième groupe pour former un doublet négatif faible. Dans la position de grossissement minimum, l'élément de zoom frontal est largement séparé du troisième groupe pour créer une forme Galiléenne de téléphoto inverse. L'élément de zoom arrière et le diaphragme se déplacent ensemble pour maintenir la collimation du faisceau de sortie et pour garder le diamètre du faisceau de sortie sur l'axe à une valeur constante.

Abstract: The doctor device has a profile member pivotally mounted to a retaining member that is carried on a mount. Vertical movement of the mount causes angular displacement of the profile member thereby changing the material applicaton area disposed adjacent and upstream of the doctor. The doctor is either a doctor blade or roll doctor. In the case of a roll doctor, a receptacle is formed in the profile member and the roll doctor is magnetically retained with the receptacle. During application of a material to an application surface with the roll doctor, the roll doctor is magnetically attracted to the application surface by a second magnetic device located beneath the application surface or work surface.

Abstract: A waste product of the treatment of scrap metal and similar and steelmaking consists of a metal dust containing oxides of various metals, in particular iron, aluminium and zinc, in differing proportions by weight depending on the type, which must be disposed of. Until now, this type of metal oxide dust, which is produced for example in foundries, has been discharged onto refuse dumps. This practice is obviously environmentally unsafe as well as uneconomical. The solution proposed by the invention is to use the metal oxide dust to coagulate and strip colloidal solutions of lacquer sludge or lacquer overspray produced during lacquering of motor vehicles.

Abstract: The invention relates to a polymer composition in which at least one of the polymers has a high melting point (> 250¤C) and in which at least one of the polymers is obtained by polycondensation. The polymer composition is obtained by mixing a prepolymer of a high-­melting polymer with the melt of a thermoplastic polymer, after which the resulting mixture, is ground and subsequently after-condensed at a temperature of 200-360¤C during 1-40 hours. 
     The polymer composition possesses unique properties with respect to the chemical and thermal resistance and for this reason is eminently suitable for processing into ovenware.

Abstract: A video processing system for generating an output sequence of video frames which, over time, a decreasing proportion of successive frames is drived from a first video input (A) and an increasing proportion of said frames is derived from a second input (B); an effect known as a wipe. A framestore (14) stores a frame of wipe-shape pixel signals wherein the value of each pixel represents the time at which the spacially corresponding output pixel is derived from the second video input signal. The wipe shape pixel signals are compared with a reference value (R), in response to which input signals are combined, and the reference value is adjusted between frames to create the wipe effect.

Abstract: The implantation probe (1) has each cathode (3) to be installed in the electron guns of a trichrome cathode ray tube fitted over the end of the implantation electrode (1), and retained by a low vacuum communicated through a central drilling. The electrode end is enlarged to fit closely inside the cathode. When an electron gun is moved towards a supported cathode (3), an eyelet (14) carried on an integral mounting (14A) passes over the latter and engages an enlarged diameter at its rear end (19). If the eyelet is misaligned, the cathode tilts about the enlarged electrode (1) end and can still be positioned in relation to the gun's grid (G1) by an associated actuator (2). After the cathode is soldered in place, the actuator (2) withdraws the implantation electrode (1). An articulated joint at the actuator end allows free movement to ensure that the cathode is not damaged in the process.

Abstract: The method is performed within a single chamber in the inside of which the fabric is continuously moved. The application of the treatment agents is performed by making use of "polyfunctional fluids" or instantaneous transit, violent reaction ccompounds, and each said fluids includes a component for contributing the chemical energy agents and a component for contributing the kinetic and thermal energies to draw the previous components onto the fabric and make them to react. Both components are carried in suitable fluids, and the process conditions are elected such that the resulting liquid product amounts are just the amounts suitable to carry the reagents to the desired depth in the fabric, and the energy levels enough to per­form the application and the reactions without harm to the fabric. 
     The apparatus comprises a single chamber having therein a series of return cylinders (7, 8) for conducting the fabric, and double action injectors (9) for the several fluids, arranged at the location of the said cylinders. The apparatus may comprise fabric input and output devices with seals to permit a superpressure to be created within the chamber; the output sealing device may be a hydraulic dam containing a bath that can be used for a final treat­ment of the fabric.

Abstract: The sensor (FT) comprises an image section (IP) and a storage section (SP) and a parallel-in, series-out shift register section (SR), both shielded from radiation . The image pick-up device also comprises a shutter device (SH, SHM) for interrupting the incidence of radiation on the image section (IP) during a period for the information transfer (FTD) in accordance with the accordion principle. In the case of a partially local interruption of the incidence of radiation on the image section (IP) the information transfer in accordance with the accordion principle locally starts at this interruption and follows it with the continuing local interruption of the incidence of radiation. An improved picture quality is obtained when displaying the generated picture signal because of the even transfer which is thus obtained instead of the known abrupt transfer following a total interruption of incidence of radiation.
