A system is disclosed for securing registration of a patterned embossing roll with a similarly patterned printed moving web. The purpose of the embossing roll is to indent the surface of the printed web in register with the printing in certain designated areas. In one embodiment, a series of randomly spaced register marks on the printed web selvage edge and identically spaced register marks on the embossing roll are viewed by appropriate scanners. Electrical signatures representing the two sets ...

A device is shown in the preferred embodiment of the present invention for holding a knitting pattern and for indicating the pattern position. The pattern is held to a pattern support face of a pattern support member by a clip member. The pattern position is recorded and visually summarized at a single location by a single notation member. Specifically, the notation member includes an elongated bar member movably mounted on the pattern support member for visually underscoring the row of the patt...

A multiple pattern sewing machine is provided with a first group of switches which are always visible and functional for selecting a pattern from a first group of stitch patterns which the sewing machine is capable of sewing. A second group of switches is concealed beneath a cover member. Also concealed by the cover member is a plurality of information bearing pivotally mounted plates. The machine contains circuitry for sensing which of the plates is exposed and dependent thereupon, the second g...

The scanner of the pattern recognition machine scans a pre-printed document containing a number of patterns which correspond to the number of test bits to be produced. There are two distinguishing patterns which produce binary one and zero bits. The patterns are printed in a sequence dictated by the desired test bit pattern. The resulting binary bits forming the test pattern are applied to the recognition logics. The pre-printed document also carries a set of patterns which, when scanned, produc...

A method and an apparatus for inspecting a high density pattern in which a signal obtained by scanning a mask substrate having a high density pattern including repeated pattern portions is collated and compared with the signal obtained from original data used to generate the pattern. Repeated pattern data corresponding to the signal obtained by scanning said mask substrate and the repeated basic pattern data corresponding to the basic pattern of the repeated pattern portion are repeatedly collat...

A pattern recognition apparatus and method, the apparatus comprising a correlation calculating circuit for calculating first correlations between each part of a image pattern data and a reference pattern data, the first correlation being expressed as R(X), where X is a variable factor representing a region storing the part of the image pattern data, and also comprising a second correlation calculating circuit for recognizing the position of a pattern most identical to the reference pattern by em...

A method of producing a pattern for use in the manufacture of a mold which is adapted to be cured by microwave irradiation. The method comprises forming a rolled-over male pattern, forming a rolled-over female pattern having a scale-off layer along a boundary thereof with the male pattern, removing the scale-off layer, pouring a silicone RTV rubber into a cavity of the female pattern to form a match plate therein, setting a metallic frame on the match plate, filling the interior of the metallic ...

A pattern forming material contains a siloxane polymer having the general formula: ##STR1## [wherein R, R' and R" are the same or different and are respectively one member selected from hydrogen, an alkyl group or a phenyl group; X is one member selected from fluorine, chlorine, bromine, iodine and a --CH.sub.2 Y group (wherein Y is one member selected from chlorine, fluorine, bromine, iodine, an acryloyloxy group, a methacryloyloxy group, and a cinnamoyloxy group); and l, m and n are respective...

The present invention contemplates a new plastic foam material which may be used to fabricate patterns for use in the Full Mold or Lost Pattern Foundry Process. Moreover, the present invention contemplates the application of organo metallic compounds to the situs of the plastic foam patterns used in the Lost Pattern Process, whereby the plastic foam patterns are vaporized during the casting process without the formation of solid carbon decomposition products. This means the casting is made in th...
