Abstract: MOLECULAR PROBING FOR HUMAN T-CELL LEUKEMIA AND LYMPHOMA    Abstract A very specific area of chromosome 10. band q 11 is taught to be the site of chromosome breakpoints which occur in the course of translocations. The translocation brings sequences of the T-cell antigen receptor delta locus into adjacency with the spe-cific area on chromosome 10. The area of chromosome 10 is presumed to carry an oncogene which is activated by the proximity to the delta locus. Methods and molecular probes and primers are taught for determining the presence of this particular translo-cation.

Abstract: An optical character recognition system which automatically reads handwritten characters and the like which do not have to be printed in a special format, utilizes a computer with memory into which digitized pixel information from a page containing characters to be recognized are entered.  The characters are assigned fields and are processed and recognized one at a time.  A bit map is formed in memory of the character in a matrix of rows and columns (x-y coordinates) representing the pixels of the pattern constituting the character.  The bit map is thinned to form, in another area of memory, another bit map of pixels arranged also in a matrix of rows and columns in x-y coordinates, of the skeleton (along the center of the pattern of pixels) of the character bit map.  The skeleton pixel matrix and the character bit map are encoded into a plurality of recognition tables each with a string of codes.  The table derived from the skeleton pixel matrix describes, with connection codes, the internal structure, row by row in accordance with the relative position of pixels in adjacent rows.  Recognition tables derived from the pattern bit map and from the skeleton pixel matrix describe the character in terms of the relative position of the pixels along the borders of the character and provide a plurality of recognition strings, one in each table, for the front and rearviews of the character and for the shape of the holes in the character which are opened from the top (as in the numeral four) or opened from the bottom (as in the numeral seven).  The recognition table derived from the skeleton pixel matrix is generated by reducing the connection codes to single codes for each line which embrace and characterize generally, rather than specifically, the connection codes for that row.  From the recognition tables, the characters are recognized by searching recognition files containing blocks of successions of lines of code corresponding selectively for the codes in the recognition tables.  The recognition file is arranged in hierarchal order so that the blocks in the file which represent characters having the lowest level of recognition difficulty in the character set to be recognized are searched first, the next highest level next and so forth.  Generally, but not exclusively, the search for each character in the set is headed by a search through a block in the recognition file which excludes that character so that recognition can proceed to the blocks for the next character in the group of blocks for the same difficulty of recognition level or to blocks for the next level of recognition difficulty.  In this manner characters are recognized with a high degree of reliability and an indication of failure to recognize the character occurs rather than misrecognition.

Abstract: Patte de scellement en plastique pour mur creux, présentant des bras pliants (11, 12) destinés à une insertion dans une ouverture de diamètre limité, située dans un substrat tel qu'un mur (30). Les bras situés à proximité de leurs zones de fixation se chevauchant sont configurés pour former une intersection à "fil de couteau tranchant" (25 a, b), de sorte qu'un espace situé entre les bras fixés est éliminé pendant le pliage et l'insertion dans l'ouverture. Les bras (11, 12) portant la charge sont épaissis de manière concomitante et ainsi renforcés dans la dimension limitée permise par l'ouverture. Selon un autre mode de réalisation, les dimensions globales de la patte sont réduites, tout en maintenant les dimensions des bras portant la charge, permettant ainsi d'utiliser un diamètre plus faible pour l'ouverture d'insertion, sans diminuer la résistance de maintien de la patte de scellement.

Abstract: Le réseau d'une telle antenne est constitué typiquement d'éléments rayonnants omnidirectionnels dont les signaux de réception sont pondérés par des coefficients complexes de pondération permettant d'ajuster leur phase et leur amplitude, et sommés par un circuit de formation de faisceau par le calcul pour synthétiser des voies de réception Les diagrammes de rayonnement obtenus pour les voies de réception ont l'inconvénient d'avoir un important niveau de rayonnement parasite de part et d'autre du lobe formé et d'avoir un faible rendement énergétique. Selon l'invention, on lutte contre ces défauts en composant le réseau d'une telle antenne à l'aide de sous-réseaux (20) qui sont constitués chacun d'un assemblage d'antennes élémentaires fixes (21, 22, 23, 24) associées à des déphaseurs individuels réglables (25, 26, 27) et qui sont dotés de directivité et orientables en azimut par réglage des déphaseurs individuels réglables (25, 26, 27) associés à leurs antennes élémentaires. Les sous-réseaux (20) de par leur directivité propre contribuent à une réduction significative en niveau et en étendue angulaire du rayonnement parasite présent dans un diagramme de réception obtenu au niveau du réseau par formation de faisceaux par le calcul.

Title: Dynamic breakwater and pumping system
Inventor: FREELAIN KENNETH W
IPC: E02B3/06
Filed: 1993-04-01
Abstract: ABSTRACT OF THE DISCLOSURE               A dynamic breakwater system pumps water from a body of water in response to wave action or underwater currents. A submerged stationary base is fixed to a solid subsurface. A breakwater protrudes upwardly through the surface of the water. Wheels support the breakwater for displacement on the base along a generally horizontal displacement axis. Springs acting against opposing sides of the breakwater urge it to a rest position between two horizontally extreme positions, and wave action and underwater currents against either side of the breakwater produce a reciprocating movement of the breakwater along its displacement axis. A pump pumps water in response to the reciprocating movement. The pump has a large piston spaced from the pump housing by roller assemblies. A door permits access to the pump interior for removal of debris or for repair, and a locking mechanism fixes the breakwater to the base to arrest pumping action for such purposes. Brush assemblies attached to the breakwater sweep debris from the base in response to the reciprocating motion, ensuring that the breakwater continues to displace.

IPC: G01D3/02
Filed: 1991-10-24
Abstract: ABSTRACT OF THE DISCLOSURE    A process variable transmitter which has a manual adjustment for span and zero or the like.  The adjustment has a finer adjustment range where the output changes responsive to changes in the position of the adjustment.  The adjustment has a coarse range where the transmitter output changes automatically as a function of time to provide coarser adjustment.  An operator can move the adjustment back and forth between the adjustment ranges until a desired output value is observed.  When adjustment is complete, the operator can manually select the desired transmitter output value and then a selection circuit stores the setting in non-volatile memory.  After a setting is stored, the transmitter output is not sensitive to movement of the manual adjustment, but instead controlled by the stored setting.
