Title: Graded powder coatings for magnetic applications and process for producing the same
Inventor: LEFEBVRE LOUIS-PHILIPPE
IPC: B22F1/102
Filed: 1997-07-24
Abstract: A method for producing composite insulating coatings on powder particles, the coatings containing an electrically insulating metal compound and an organic polymer. The coatings are deposited preferably by controlled spraying, simultaneous or sequential, of sol precursors of insulating metal compounds and polymer emulsions or solutions onto polymer, metal or ceramic powder particles preferably during the blending or mixing of the particles. The process is useful for mass production of coated iron-based powders used for shaping components by powder metallurgy techniques for magnetic applications. Coated iron based powders can be cold or warm pressed and heat treated to obtain the desired mechanical properties.

Title: Cross-connect method and apparatus
Inventor: MILLER ARTHUR O
IPC: H01H67/26
Filed: 1996-03-19
Abstract: A remotely controlled cross-connection switching matrix, particularly suited for telephone systems, has a jumper pin (40) picker and placement mechanism selectively movable along each of three axes under the control of a single drive motor (102) translating a single drive cable (100) over a series of pulleys (99, 101, 103-108, 110, 111). Movement along the selected axis is effected by braking movement along the other two axes. The system provides a "soft dial tone" to prospective telephone subscribers' (151) premises having cable pairs (152) permanently connected to the matrix (10). The cable pair for the calling prospective subscriber is automatically identified at the matrix in response to an off-hook status for that prospective subscriber, and the cable pair identification data is automatically transmitted to the telephone business office. Stored information at the business office for the premises of the identified cable pair is automatically displayed for the telephone company representative responding to a request for service by the calling prospective subscriber. The matrix also permits remote selective connection of unused telephone lines to a test bus (185) connected between the matrix (10) and the central office, thereby permitting automatic, remotely controlled testing of those lines.

Abstract: A phase detection circuit detects a phase of a phase detection signal output from a complex multiplication circuit.  A frequency error detection circuit detects a frequency error of a phase-detected signal, with the first frequency error detection characteristic in which a first frequency domain is defined as a detection range.  An average circuit converts a signal having the detected frequency error into a signal having a second frequency error detection characteristic in which a second frequency domain other than the first frequency domain is defined as a detection range.          After the average circuit calculates an average of frequency error signals for each period of time, it converts an average signal into a signal having the original first frequency error detection characteristic and outputs it to an AFC loop filter.

Abstract: A process for removing creases from a film eliminates a problem in the quality of the heat seal for a patch bag having at least a segment of one or more bag side edges (or the bag bottom edge)covered by one or more patches. The film creases are removed by inflating the film tubing which is later converted to a bag, heating regions containing the creases with a heating means to a temperature which, in combination with the pressure within the inflated tubing, causes the creases to relax. The heated crease-containing regions are then cooled and the inflated tubing is deflated and wound up in a new configuration in which at least one patch covers at least one side edge or the bottom edge.

IPC: G01N21/85
Filed: 1998-04-20
Abstract: A color-sorting machine for granular materials (1) optically detects raw material grains (G) falling along a substantially fixed path (A) and sorts out no-good grains by color.  An optical detection unit (21; 230) to this end comprises a condenser lens (9; 90), a plurality of optical filters (10a, 10b; 100a, 100b, 100c), and a plurality of light-receiving sensors (12A, 13B; 120a, 120b, 120c) corresponding to the filters and can detect a plurality of wavelengths.  The light-receiving sensors (12A, 13B; 120a, 120b, 120c) lie side by side on the same plane, are formed in a unit body, require no positioning adjustment among the light-receiving sensors, and make it possible to reduce the size of the light detection system.  A prism (11; 110) is provided between the condenser lens (9; 90) and the light-receiving sensors.  The prism has light path diffraction surfaces (11a, 11b; 110a, 110b, 110c) of the same number as the light-receiving sensors, so that the light-receiving sensors receive light of the same point of view and can perform color sorting.  Detected light partition plates (15; 150a, 150b) are provided between adjacent light path diffraction surfaces of the prism and between the corresponding adjacent light-receiving sensors to improve the precision of optical detection.

Title: Process and apparatus for direct chill casting
Inventor: CARRIER CLAUDE
IPC: B22D11/049
Filed: 1998-05-19
Abstract: A process and apparatus are described for direct chill casting.  The apparatus comprises an open ended mould cavity formed by a casting surface with an upper and lower end.  A refractory sleeve is located at the upper end of this mould cavity and has an inner diameter less than the inner diameter of the mould, whereby the sleeve forms an overhang with the mould cavity.  This sleeve is adapted to receive molten metal. Below the lower end of the mould, means are provided for supplying coolant to chill the descending hot metal body thereby forming an ingot.  A permeable wall element is disposed in the peripheral wall of the mould cavity below the overhang and this element has an inner wall forming part of the cavity.  Means are provided for feeding gas into and through the permeable wall element to discharge through its inner wall.  An annular oil plate is mounted between the overhang and the permeable wall element and this oil plate has grooves in its bottom face thereby providing access for lubricating oil to the mould cavity.  An oil supply means for feeding a volumetrically controlled amount of lubricating oil through the grooves to the mould cavity.  In this way, oil and gas are supplied to the mould cavity to form an oil and/or gas layer between the metal and the wall of the mould.

Filed: 1998-01-23
Abstract: La présente invention concerne une stratégie d'exposition hybride pour la génération de motifs qui utilise une déviation du balayage ligne par ligne à champ large et une plage de projection à déplacement uniforme de façon à exposer des bandes longues. Le balayage analogique périodique en champ large par procédé magnétique est augmenté d'un balayage rétrograde grande vitesse par procédé électrostatique de façon à garder stationnaire le faisceau pendant l'exposition de zones à éclairs rectangulaires. Le chemin de données du système utilise un motif représenté en format tramé. Des bases de données de vecteurs intermédiaires sont créées à partir de règles de fracture limitant la caractéristique et la taille hiérarchique de cellule de façon qu'elles soient inférieures à celles des franges de chevauchement des zones de données des bandes. On emploie des zones à éclairs rectangulaires, chaque zone étant une matrice 1 par n de pixels écriture. La longueur, la position origine et la dose des éclairs de faisceaux linéaires peuvent être augmentées ou diminuées de façon à permettre l'exposition des motifs sur une grille de dessin bien plus petite qu'un pixel écriture. Les données longueur, position origine et dose de chaque éclair sont déduites du format de données tramées au moyen d'un dispositif décodeur. De cette façon, de multiples pixels écriture sont exposés simultanément sans compromettre la résolution ni les irrégularités du bord de ligne diagonale, augmentant ainsi le coefficient d'exposition. On garantit une cadence d'éclairs élevée en incluant un éclairement astigmate tendant à maximiser le courant du faisceau, et en incluant une déviation de mise à blanc et de mise en forme coplanaire moyennée tendant à minimiser les tensions d'attaque.
