Abstract: A bag palletizer  has a frame equipped with two tier guides, two pallet lift mechanism, two stacker work stations, and a lift control at each work station.  A belt conveyor delivers bagged articles successively to both work stations.  A pallet is supported on each pallet lift mechanism and raised until it abuts the bottom surface of the associated tier guide.  Bags are manually removed from the conveyor and placed atop the pallets to form a lowermost tier on each pallet.  After each lowermost tier is formed, the pallets are lowered by the respective lift mechanisms the height of one tier to provide sufficient space in the tier guides to form another tier atop the lowermost tier. These steps are repeated until a selected number of tiers are stacked atop each pallet at which time each pallet and its stack of bags are removed.

Abstract: L'invention concerne un détecteur numérique pour la radiographie et la fluoroscopie. Ce détecteur comprend un panneau plat à grande surface qui se monte aisément dans un râtelier Bucky de salle de radiologie. Le détecteur utilise une couche d'un matériau photoconducteur (c'est-à-dire, selon le mode de réalisation préféré, du a-Se) pour détecter les rayons-X et convertir l'énergie de ces rayons en charge, ainsi qu'un dispositif à matrice active constitué de transistors à couche mince, se présentant sous la forme d'un circuit intégré à très grande surface, pour l'affichage de la charge. Une structure à deux grilles est utilisée pour le dispositif à transistors à couche mince, la grille supérieure constituant un prolongement de l'électrode de pixel, de sorte que l'on obtient une protection desdits transistors à couche mince contre les hautes tensions. Un condensateur de stockage de pixel intégré est conçu pour permettre une absorption améliorée de l'énergie des rayons-X avec une faible tension de pixel, un faible courant de fuite et une grande constante de temps de fuite de la charge. Dans le mode de réalisation préféré, on crée le condensateur de stockage de pixel intégré en faisant chevaucher l'électrode de pixel avec une ligne de grille adjacente ou une ligne de masse séparée faisant partie du dispositif d'affichage à matrice active. L'efficacité de collection des charges d'images est améliorée dans le dispositif d'imagerie selon la présente invention par le fait que la répartition des champs électriques dans la couche de matériau photoconducteur est altérée de sorte que les charges d'image se déposent sur les électrodes de pixel et non sur les transistors à couche mince d'affichage. Ce dispositif comprend également une photominuterie qui est intégrée au détecteur d'imagerie pour mesurer le temps d'exposition aux rayons-X.

Abstract: Apparatus, device and method for improved slicing of large food sticks, loaves and the like are provided.  A slicing blade which has a top flat surface or top flat land width along its cutting edge provides generally longitudinal forces on the food product being sliced, which forces are in a direction generally opposite to the direction through which the food products are fed through a slicing apparatus.  The slicing blade includes a bottom primary bevel land width surface and an advantageous primary angle for imparting improved stack and slice uniformity and for controlling package overfill. The slicing blade also exhibits a long slicing blade surface which follows an Archimedean spiral.  The invention is particularly important in improving handling of large luncheon meat sticks, especially non-frozen, high water content and reduced fat content luncheon meat sticks.  Fast feed rates can be practiced without experiencing jamming, yields are increased, slice and stack quality and sizing are made more consistent and repeatable, slicing line utilization is enhanced, and sanitary conditions are more easily maintained.

Inventor: BOONE KEITH
IPC: G06F17/27
Filed: 1996-07-19
Abstract: This invention provides a method and apparatus for automated search and retrieval processing that includes a tokenizer, a noun phrase analyzer, and a morphological analyzer. The tokenizer includes a parser that extracts characters from the stream of text, and identifying element for identifying a token formed of characters in the stream of text that include lexical matter, and a filter for assigning tags to those tokens requiring further linguistic analysis. The tokenizer, in a single pass through the stream of text, determines the further linguistic processing suitable to each particular token contained in the stream of text. The noun phrase analyzer annotates tokens with tags identifying characteristics of the tokens and contextually analyzes each token. During processing, the noun phrase analyzer can also disambiguate individual token characteristics and identify agreement between tokens.  Themorphological analyzer organizes, utilizes, analyzes, and generates morphological data related to the tokens. In particular, the morphological analyzer locates a stored lexical expression representative of a candidate token found in a stream of natural language text, identifies a paradigm for the candidate token based upon the stored lexical expression, and applies transforms contained within the identified paradigm to the candidate token.
