A technique for detecting defects in stationary products or in products moving on a production line (102, FIG. 12) by analyzing their images uses a matrix or line-scan camera (104, FIG. 12) for taking images of products (102). The product's dimensions are measured with accuracy and the sizes and positions of their surface defects are determined. The technique is much faster and more accurate than current techniques and is based on an analysis of the histogram of the full image (C, FIG. 2). A car...

Apparatus to develop sensitized emulsion coating on a metallic base sheet comprises: A. a sequence of sheet conveying rollers rotating to convey the sheet generally horizontally in a forward direction and with the coating exposed vertically, B. treating means to deliver and direct different liquids into contact with said coating at different stations during sheet forward conveyance, C. and multiple squeegees which are spaced in said direction to engage said coating during said conveyance and to ...

A method, and apparatus to practice the method, to complete multiple (triple) branch wells using separate drill and casing templates. Principally this invention finds its greatest utility in the in situ leach mining of deep lying ore bodies. Initially, a generally vertical main hole is drilled in the earth and cased. The particular casing used has an internal indexing dog and specific areas which act as windows from which some of the branch wells are to be drilled. To form the individual branch ...

The present invention solves the problem of repeated operator intervention in a vision system by providing multiple templates which may be used to locate an object within an image.

A method for creating a message template used for embedding hidden messages, the method includes the steps of determining a message template performance metric comprising a dispersal measure having both a spatial domain function and a frequency domain function; developing a numerical optimization algorithm containing the message template performance metric as a basis for optimization; determining the message template geometric configuration comprising: (i) determining a message template capacity...

A template selection method involves providing a plurality of templates representing a type of cardiac event. One or more characteristics of each template are evaluated. The evaluations are compared and a template is selected as a current template based on the comparison.

A tracking valve which can be mounted on a tool-supporting carriage in a machine tool and whose main valve member is a spool which is movable axially in a valve body to thereby start a hydraulic motor for the carriage so that the motor can move the carriage relative to a template while simultaneously moving one or more tools relative to a workpiece. The spool has a relatively large surface at one end, a relatively small surface at the other end, and an axial bore for a pilot valve member which i...

A method and apparatus are disclosed for leveling a relatively massive template structure which is positionable on the ocean bottom in proximity to one or more sites of subterranean wells. Since the template is primarily utilized to mount or guide later applied drilling, completion or production equipment, it is essential that the template be positioned on its fixing piles in a precise horizontally level position. Accordingly, a plurality of sleeves are secured to the template which respectively...

Artwork for a sign is outlined on paper or other dielectric sheet material with pencil lead or other electrically conductive marking material to form a sign pattern. A pair of spaced apart electrodes are arranged to receive the outlined sheet material between them, and they are energized for intermittent conduction between predetermined areas thereof only when said conductive marking material is interposed between said areas. The sheet material and electrodes then are moved relatively one to the...

A rotatable and reciprocating device for supplying material workpieces to be shaped to a shaping tool comprises a platform to which the workpieces are attached, a template disposed adjacent the platform, a guide member abutting the template, and a biasing means cooperating with the platform for constantly maintaining the template and guide member in abutment. In one embodiment, the guide member or template are attached to an axle for the rotatable platform while the other of these members is sec...
