Abstract: Disclosed is a structural member for use as a vertical supporting post in a merchandise display racks. This member is made of two identical, longitudinally extending end plates that are W-shaped in cross-section and oriented in  such  a  manner  as  to  face  each  other,  and  of  two identical,  longitudinally extending side plates that are welded to the end plates to join the same and form the member.  The end faces of the end plates are provided with three parallel rows of longitudinal slots for use to hook a footing at the bottom of the post, or one or more shelves along the same.   With very slight changes only, the side plates may also be used as tie-bars for interconnecting the posts of the rack.

Abstract: A rotating liquid distributor, comprising a circular distributor housing (1), consisting of an upwardly open annular channel (1a), in whose bottom there are spaced outlet openings (2) at an even mutual distance. A supply pipe for liquid under pressure is centrally mounted in the distributor housing (1) and is connect-ed to a vertical, rotatably mounted hollow rotor stem (5) with an upper transver-sat hollow rotor arm (6) with downwardly slanted nozzles (7), flush with the out-let openings (2) to produce a turning moment through the supply of liquid under pressure. Nozzle (7) is surrounded by a screen (8) with an upside down U-shaped 'cross section with sidewalls (8b) which extends down into the annular channel (1a) on each side of nozzle (7) in order to catch liquid splashed. A  trans-porting means (9) which fills out the cross section of the annular channel (1a) is fastened by means of a draw bar (10) to rotor arm (6). Thereby any particle de-posits in the annular channel will loosen and liquid leaks will be transported to and forced through the outlet openings (2). Accumulation of liquid in the lowest portion of the annular channel is avoided, through a slant position of the liquid distributor, and an even distribution of supply of liquid to the outlet openings is achieved. Thereby there is achieved even fertilization by using aid liquid distrib-utor with connected equipment when driven across uneven fields:

Abstract: A starch hydrolysate composition is particularly suited for use as a sequesterer, i.e. it readily interacts noncovalently with other molecules to form stable inclusion complexes which are useful in a variety of applications. The starch molecules in the compostion which act as sequesterers are in the form of single helical inclusion complexes with starch molecules having a D.P. of about 10 to 200 and a weight-average D.P. of about 10 to 50 as the host molecule holding one or more guest molecules within their internal cavities. These hydrolysates are prepared by first converting amylopectin molecules from the double helix form to the single helix form and then by cleaving chain segments from the molecules. The sequesterers are principally useful in the agrichemical, food and pharmaceutical areas, as powderizers, stabilizers, reducers of volatility and toxicity, bioavailability enhancers and controlled release agents.

Abstract: A method and system for automatically modifying an original transcription produced as the output of a recognition operation produces a second, modified transcription,  such as, for example, automatically correcting an errorful transcription produced by an OCR operation.  The invention uses information in an input text image of character images and in an original transcription associated with the input text image to modify aspects of a formal image source model that models as a grammar the spatial image structure of a set of text images. A recognition operation is then performed on the input text image using the modified formal image source model to produce a second, modified transcription. When the original transcription is errorful, the second transcription is a corrected transcription. Several aspectsof the formal image source model may be modified; in particular, character templates to be used in the recognition operation are trained in the font of the glyphs occurring in the input text image. When errors in the original transcription are caused by matching glyphs against templates that are inadequately specified for the given input text image, the subsequently performed recognition operation on the text image using the trained, font-specific character templates produces a more accurate transcription. Another image source model modification includes constructing a formal language model, based on a character n-gram technique, that models sequences of character n-grams occurring in the original transcription. In one implementation, the 2D image model is represented as a regular grammar in the form of a finite state transition network.
