Abstract:
1389124 Sampling granular material E KELLY 10 April 1973 [17 Aug 1972] 38330/72 Heading B8N An apparatus for continuously taking a sample from a stream of falling material comprises a hollow sampling member CY rotatable about a horizontal axis and provided with one or more inclined slots S, S1 or S2, which traverse the width and breadth of the stream upon rotation. The material falls from an adjustable outlet of a feed hopper FH on to the revolving sampling member and a sample is taken in through the slots and discharged from the drum mainly at both ends into a collecting hopper with the aid of a guide plate (GP), Fig. 2 (not shown), the sample being directed to a collection point or to a point for further sampling. The bulk of the material from the hopper FH is deflected to each side by the outer revolving surface of the sampling member. The size of the slots may be adjusted by movable plates (A), Fig. 3 (not shown).
Abstract:
A multi-layered support structure provides ergonomic, adaptable seating support. The multi-layered support structure includes multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each include elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The multi-layered support structure also uses aligned material to provide a flexible yet durable support structure. Accordingly, the multi-layered support structure provides maximum comfort for a wide range of body shapes and sizes.
Abstract:
A camouflage system and methods of making a composite camouflage pattern. The camouflage system comprising more than one design layer, wherein the one or more design layers may be a different monochromatic color or the same monochromatic color of another design layer. At least one of the design layers may include fading of a monochromatic color and the one or more design layers may be combined to produce a composite camouflage pattern.
Abstract:
Disclosed are methods for identifying molecular interactions between DNA sequences and proteins in vivo. The methods of the invention employ known or suspected DNA-binding proteins and genomic DNA in a plasmid library. Interacting molecules direct the expression of a reporter gene, the expression of which is then assayed. Also disclosed are genetic constructs useful in practicing the methods of the invention.
Abstract:
An apparatus and method for molding a component onto a stretched blank. The apparatus includes a stretching assembly (14) mounted adjacent a first mold part (12). The stretching assembly includes a plurality of clamp assemblies (18a-18d) that grasp the peripheral edge of the blank and a plurality of slide assemblies (40a-40d) that move the clamp assemblies away from one another to apply a stretch to the fabric.
Abstract:
An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.
Abstract:
A decorative display system may include a placard configured to be mounted on a supporting surface, the placard having a plurality of horizontal grooves and a mounting accessory. The mounting accessory may include a mounting portion configured to interface with one or more of the horizontal grooves and a support portion for support an item to be displayed. The mounting accessory may be positioned at a plurality of positions relative to the placard. In some embodiments, the decorative display may include a plurality of vertical grooves for mounting accessories.
Abstract:
A method of manufacturing a piezo-composite element comprising a ceramic element (12) embedded in a polymer (14) such as epoxy for use in an ultrasonic transducer (10) includes first grinding the face of the composite and removing damaged ceramic (12) by acid etching the ceramic (12). The epoxy is then removed by plasma etching so that the ceramic (12) is slightly elevated above the epoxy. The composite is sputter plated so that a maximum temperature that could damage the p1a ting is not exceeded. The ceramic (12) is then poled so that a maximum temperate re that could damage the plating is not exceeded. Contacts (16) are then attached to the plating adjacent the ceramic (12). In an array, the ceramic elements (1 2) may be in the form of posts. The plurality of ceramic elements (12) is in staggered arrangement with the polymer (14).
Abstract:
Expression vectors that include a pre-selected therapeutic nucleic acid operably linked to a tumor specific or cell type-speci fic promoter and a Tcf-4 beta -catenin enhancer are provided. The therapeutic nucleic acid preferably includes a gene encoding a therapeutic protein for treatment of, for example, cancer. Methods for targeted expression of therapeutic nucleic acid, and methods for treating cancer, utilizing the expression vectors described herein, are also provided. Host cells are also provided that have been transformed with the expression vectors described herein.
