Title: Constant angle conveyor belt cleaner
IPC: B65G45/12
Filed: 1990-04-19
Abstract: A conveyor belt cleaner (10) for removing residue from the surface of a conveyor belt (14) is disclosed. The conveyor belt cleaner (10) is radially adjustable through connection with a rotatable support member (12, 18) positioned generally transverse to the direction of conveyor belt travel.

Title: A method for distinguishing between voiced and unvoiced speech elements
Inventor: MUMOLO ENZO
IPC: G10L25/93
Filed: 1990-05-11
Abstract: The spectra of voiced sounds lie predominantly at or below about 1 kHz. The spectra of unvoiced sounds lie predominantly at or above about 2 kHz. It is known to determine the lower- and higher-frequency energy components contained in a sound or sound element, to compare these energy components, and to use the result of the comparison to make a voiced-unvoiced decision. Since the distributions relative to voiced and unvoiced segments are overlapped, false decisions are liable to occur. The invention is predicated on the fact that a change from a voiced sound to an unvoiced sound or vice versa always produces a clear shift of the spectrum, and that without such a change, there is no such clear shift. From the lower-and higher-frequency energy components, a measure of the location of the spectral centroid is derived which is used for a first decision. Based on the difference between two successive measures, a second decision is made by which the first can be corrected.

Title: A method and composition for treating metal surfaces
Inventor: JONES LAWRENCE E
IPC: C09D129/04
Filed: 1993-11-30
Abstract: A method and composition for treating metal surfaces to improve corrosion resistance and paint adhesion. The composition is a non-corrosive aqueous solution including water, a polymeric compound, an additive, and dispersed silica. In a preferred embodiment, the polymeric compound may be a polymer having a plurality of carboxylic functional groups and a plurality of hydroxyl groups. The polymeric compound may be a bifunctional copolymer or the reaction product of a first polymer having a plurality of carboxylic functional groups (e.g., polyacrylic acid or polymethylvinylmaleic anhydride), and a second polymer having a plurality of hydroxyl groups (e.g., polyvinyl alcohol). The additive is selected from at least one of: (i) an acid of a group IV-B element and a weak base, and (ii) an ammonium salt of a group IV-B compound such as ammonium zirconium carbonate. An exemplary acid of a group IV-B element is fluotitanic acid and an exemplary weak base is ammonium hydroxide. Dispersed silica is added, and any attack of the silica is minimized. The method for improving corrosion resistance and paint adhesion of a metal surface includes contacting the metal surface with a composition as described above and drying the composition in place. Prior to contacting the metal surface with such a composition, the metal surface may be cleaned and rinsed.

Title: Protective iron oxide scale on heat-treated irons and steels
Inventor: AKHTAR AINUL
IPC: C23C8/14
Filed: 2000-07-07
Abstract: The invention provides a process for the heat treatment of iron-based alloys, including irons and steels, such as carbon steels and low alloy steels, in a controlled oxidative environment, to modify the microstructure of the metal to obtain both improved mechanical properties and a protective surface oxide scale. In a first high-temperature treatment, a layer of wüstite (FeO) is formed on the surface of the material and austenite forms in the interior of the material. Rapid cooling follows the high temperature treatment so as to preserve the wüstite scale and to obtain at the same time an internal steel microstructure comprising martensite or bainite. In a second step of lower-temperature heat treatment, the scale is transformed so that it comprises an intermediate layer composed predominantly of wüstite (FeO), with a surface of predominantly magnetite (Fe3O4), while the mechanical properties of the material are tailored for specific applications.

Title: Sensing moisture on screen and automated controlled wiping
Inventor: STANTON PETER ROBERT
IPC: G01N21/43
Filed: 1990-08-28
Abstract: Water (3) on the outside surface (1) of a vehicle windscreen (7) causes a light beam (5) to be partially transmitted through screen (7), while a clean screen (7) provides substantially total internal reflection of beam (5).
