Title: Process for manufactoring an electrical capacitor with polyethylene terephthalate as a dielectric, especially for use as a solderable chip element
Inventor: HARTMUT MICHEL DR RER NAT
IPC: H01G13/00
Filed: 1984-12-17
Granted: 1988-08-25
Abstract: An electric capacitor formed of dielectric layers provided on at least one side with metal layers with coatings, and wherein the layers are formed of partially crystallized and pre-shrunk polyethylene terephthalate. The coatings are alternately electrically conductively connected to metal layers applied by the Schoop process with opposing polarity to end faces of the capacitor body. The dielectric layers are arranged to form a stack or are deformed to form a flat-pressed winding. The polyethylene terephthalate dielectric layers have a degree of crystallization of at least 50%, in particular at least 55%, measured by differential thermo-analysis in order to determine the melting point enthalpy. In a method for production of such a capacitor, the capacitor bodies provided with the metal layers are subjected to an additional heat treatment in which the temperature is increased from room temperature to a final temperature of 200 DEG  to 250 DEG  C. for 1 to 5 hours. This final temperature is held for a period of 1 to 65 hours, where the length of this holding time is inversely proportional to the final temperature.

Title: Method and apparatus for fabricating composite sheets
Inventor: BROSSY PIERRE
IPC: B29C43/32
Filed: 1984-03-14
Granted: 1988-09-01
Abstract: To produce a panel of variable thickness, a stratified assembly of a layer of fibers containing a non-polymerized binder and at least one cover sheet is placed between the mold and mold-backing of a molding press. The stratified assembly is caused to conform to the interior surface of the mold or mold-backing by forcing the cover sheet against the mold or mold-backing interior. Hot air is blown into the fiber layer from the mold surface opposite the cover sheet, into at least the region that will correspond to the area of greater thickness. The direction of the heated air is reversed after a period of time, the blowing of the air being maintained and adjusted in order to secure polymerization of the binder. At the same time, the portions of the panel corresponding to areas of lesser thickness, generally the edges of an acoustical panel, are cured (the binder polymerized) by contact heating means. To effect cross-over blowing, both the mold and mold-backing are provided with ports through which heated air may be blown or passed.

Title: Pharmaceutical iodophor preparations with controlled iodine:iodide ratio and method of producing the same
Inventor: GOTTARDI WALDEMAR DR
IPC: A01N59/12
Filed: 1984-02-23
Granted: 1989-09-21
Abstract: The microbicidal effectiveness of pharmaceutical iodophor preparations comprising an organic substance which reacts with iodine to form a complex thereof, such as polyvinylpyrrolidone, iodine bound thereto in complex form, free iodine, and iodide ions, is assured by controlling the ratio of total iodine (complex bound iodine and free iodine) to iodide ions at between 2:1 and 10:1, this ratio being adjusted without chemical oxidizing agents such as iodate ions by anodic oxidation of a solution of the iodophor preparation and iodide ions. The resulting preparation can be free of chemical oxidizing ions such as iodate ions.

Abstract: This invention relates to a method forming fluorine-doped glass. A coating of glass particles is deposited on the surface of a cylindrical rod of high purity glass. The coated rod is inserted into a furnace which contains a cylindrical muffle formed of high silica content glass. A fluorine-containing atmosphere is flowed through the muffle and over the outer surface of the coating of glass particles and also flows inwardly through the interstices thereof. The temperature within the furnace is sufficiently high to cause fluorine to diffuse into the surfaces of the glass particles and to cause the particles to fuse and form a fluorine-containing dense glass coating on the surface of the rod.

Abstract: A sliding base is guided for vertical movement on an upright of the traverse mechanism. It bears a camera having its lens directed along a horizontal axis toward a vertical bank of lights. A drum supported by uprights and driven rotatingly by a motor can move back and forth on rails, while the traversing carriage bearing vertical rolls guiding a cable can likewise move parallel to the axis of the drum in order to check and, if neccessary, modify the approach angle formed by the incoming cable about to be laid on the winding. The silhouette of the zone of the winding where the turns are laid down is formed on a receiving surface within the camera, this surface taking the form of a photodiode grid, the periodic scanning of which yields signals sensing the conditions under which the cable is being wound.

Abstract: A method for determining the horizontal airspeed of a helicopter in the high speed (ve>20 m/s) range. Pitch angle and the longitudinal control signals are recorded by sensors such as an inertial navigation system and a potentiometer connected to the pilot's control lever. Equivalent speed signals are calculated from the measured pitch angle and longitudinal control signals by means of calibration equations. These signals are then filtered and weighted. The horizontal airspeed is then derived from the sum of the weighted signals divided by the sum of weighting factors k theta  and k delta x determined in accordance with the sensed pitch angle and longitudinal control signals. The horizontal velocity signal may be filtered, if necessary.
