Title: Method of hot-dip-zinc-plating high-tension steel plate reduced in unplated portions
Inventor: FUJIBAYASHI NOBUE
IPC: C23C2/02
Filed: 1994-06-24
Abstract: In connection with the manufacture of zinc hot dip galvanized or galvannealed steel strip using a high strength, high tensile steel strip containing Si, Mn or Cr as a starting steel strip, the invention provides a method for hot dip galvanizing a high tensile steel strip with minimal bare spots which can manufacture a bare spot-free steel strip of quality in an inexpensive manner while minimizing process complication and a productivity lowering.        The invention is achieved by subjecting a cold rolled steel strip containing at least one component of 0.1 to 2.0% of Si, 0.5 to 2.0% of Mn, and 0.1 to 2.0% of Cr and optionally further containing up to 0.2% of P, in % by weight, to recrystallization annealing in a continuous annealing line, cooling the steel strip, removing a steel component concentrated layer at the surface of the steel strip by polishing and/or pickling, subjecting the steel strip again to heat reduction at a temperature from 650°C to a recrystallization temperature and to hot dip galvanizing in a continuous galvanizing line, and optionally effecting overplating and/or alloying or effecting alloying followed by overplating.

Title: Shaped Semi-Solid or Solid Dishwashing Detergent
Inventor: ZINT DAVID ROBERT
IPC: C11D1/72
Filed: 1995-04-24
Abstract: The present invention provides a firm, mild, good performing, low-smear semi-solid or solid dishwashing product. The rheology of the dishwashing product is such that structural elements have been separated from functional elements to obtain best structure properties and in-use properties. By using an interlocking mesh of carboxylic acid and/or neutralized carboxylic acid fibers and/or platelets to provide a support structure, the semi-solid or solid dishwashing product can be loaded with superior performing  dishcare materials (e.g., mild surfactants) and appearance enhancers without dependence on surfactant-water phase behavior to provide the support structure. As a result, the present dishwashing product is milder than semi-solid dishwashing products currently on the market. The support structure of the present product, and preferably the use of hygroscopic surfactants, provide a product with lower smear than current gel dishwashing products.

Abstract: A hand-held power-operated hedge trimmer for trimming plant growth such as hedges, shrubs, tree branches and the like. The hedge trimmer includes a housing containing a motor assembly, a blade assembly extending forwardly in a lengthwise direction from the housing, and a drive mechanism for coupling a movable cutting blade of the blade assembly to an output of the motor assembly for causing reciprocatory rectilinear movement of the movable cutting blade relative to a stationary combing blade in response to selective actuation of the motor assembly. The cutting blade includes a series of cutter teeth formed along its opposite longitudinal edges with each cutter tooth having a compound tooth profile. The compound tooth profile includes a pair of shear tooth segments formed along opposite lateral edges of the cutter tooth and a saw tooth segment formed at its distal edge between the shear tooth segments. In addition, a series of sizing lugs are formed along the opposite longitudinal edges of the movable cutting blade between each pair of adjacent cutter teeth for establishing entrapment channels therewith. In operation, smaller twigs and branches are drawn into the entrapment channels and into alignment with the adjacent shear tooth segment for shear-cutting with a single stroke of the cutting blade. The sizing lugs prevent larger branches from being drawn into the entrapment channels so as to align them relative to the saw tooth segments for saw-cutting with a multi-stroke sawing action.

Title: Symmetrical flow extrusion manifold
Inventor: KEEHN WILLIAM T
IPC: B29C48/06
Filed: 1994-12-13
Abstract: A multiple-orifice extrusion manifold (10) is disclosed which includes a first housing (20) defining an outer chamber (170) and an extrusion wall (140). A  plurality of orifices (80), adapted for extruding a first substance from the outer chamber (170), extend through the extrusion wall (140). An inlet pipe (40) is provided in the first housing (20) for flowing the first substance into the outer chamber (170). The inlet pipe (40) is located so as to permit flow of the first substance symmetrically within the outer chamber (170). A  second housing (190) which defines an inner chamber (200) is provided within the first housing (20). The second housing (190) is located symmetrically within the outer chamber. A plurality of tubes (210) extend from the second housing (190). Each tube (210) has a first end (212) opening into the inner chamber (200) and a second open end (213) cooperatively aligned with an orifice (80) for extruding a second substance from the inner chamber (200) through the tube (210) and to within the first substance. Thus, each extrudate substance is flowed to an extrusion orifice (80) through a flow path, which is symmetrical with all other flow paths for that substance. The manifold housing (20) presents a right circular cylindrical outer surface (70) with the extrusion orifices (80) therein. The orifices (80) are equally spaced around the outer surface (70). Three blades (110) with a cylindrically rotating path about the cylindrical outer surface (70) are provided to cut a continuous extrusion at each orifice as the blade or blades pass the orifice. The blades (110) are mounted for rotation around the inlet pipe (40) which supplies an extrudable substance to the housing.

Abstract: La présente invention concerne un réacteur pour le traitement d'un liquide. Le réacteur comprend une enceinte remplie d'un lit absorbant. Une entrée est disposée dans la partie supérieure de l'enceinte pour introduire dans celle-ci à intervalle régulier un volume donné de liquide à traiter. L'enceinte comprend aussi une sortie disposée dans sa partie inférieure pour évacuer de celle-ci le liquide traité. Le lit absorbant est constitué d'une garniture poreuse capable d'absorber par capillarité le liquide introduit dans l'enceinte en vue de le traiter. Au moins un élément séparateur, perméable au liquide à traiter mais causant néanmoins au moins un bris de capillarité dans l'enceinte, est disposé horizontalement dans l'enceinte en vue de diviser le lit absorbant en au moins deux couches superposées d'une hauteur déterminée, calculée en fonction de la hauteur de la remontée capillaire du liquide à traiter dans une colonne remplie d'une couche continue du même lit absorbant. Le réacteur de la présente invention est peu coûteux à construire. Le temps de traitement est facilement contrôlable due à l'utilisation de la capillarité par la garniture poreuse, et grâce à ses éléments séparateurs, le réacteur peut ainsi être utilisé à un rendement optimal.

Filed: 1996-10-09
Abstract: The invention is a method of forming a conductive coating on a structural substrate.  The method involves depositing a relatively non-conductive precursor material in a solution state on the structural substrate using inkjet apparatus;  The solution is dried to leave a film.  Then, the dried film is heated to a level at which a chemical (pyrolysis) reaction is triggered to convert the dried precursor material to a conductive material.  The precursor solution can be dried in a manner which does not result in its transformation to the conductive state, as for example through the use of microwave apparatus.  The precursor material can be applied on the substrate in such a manner as to control the conductivity of the coating and to provide a coating which exhibits one of uniform characteristics. discrete patterns, or gradient characteristics.
