A dress pattern adapted from a master pattern that is of variable size and has a bodice section and a skirt section which are separate but adjacent one another. The pattern is based on the concept of graded measurements at the periphery of the pattern. With the exception of the center front section, the pattern is characterized by having a center front section, a front neckline, a shoulder seam, a front armhole, an underarm seam and a bust dart. The skirt section itself is characterized by the a...

A plurality of low-speed memories having stored therein a plurality of patterns and first and second high-speed memories of higher operating speed than the low-speed memories are provided. One of the first and second high-speed memories is read to obtain output patterns and, at the same time, the plurality of low-speed memories are simultaneously read and the read-out data are successively written in the other high-speed memory alternately with each other. Upon completion of pattern generation f...

A pattern assembly for use in the lost pattern process of investment casting characterized by a center tree or sprue member including a central stem and a plurality of laterally projecting collars spaced apart along the stem and united therewith to provide the surface area for gating the patterns, the cross-sectional size of the stem being greater than the projecting width of the collar, whereby the stem serves to form a riser.

A pattern mechanism for a knitting machine which is adapted to selectively control longitudinal movement of needles in their slots. The needles are provided with jacks in operating relationship thereto for moving the needle in a longitudinal direction. A separate butt element is carried by the jack and is movable relative to the jack both longitudinally and transversely in at least two alternate modes. One of the modes provides lesser longitudinal free movement of the butt element relative to th...

Two sets of rectangular shaped tiles in the form of dominoes are provided. Each set of tiles are divided in half to form perfect squares. Each square of the first set are provided with separate identifiable indicia such as color or touch. One square of each tile of the second set of tiles contain a third indicia different than the first two squares on the first set of tiles. The second square on each of the second set of tiles contain the same indicia as the first square on the first set of tile...

A work support table having a plurality of removable working surfaces or elements. The table may be constructed in sections joined by means such as hinges. Support surface capturing strips or lips may be mounted on each section of the table about the periphery thereof except for that edge or edges along which the section is joined to another section. When the table is folded, the removable work surfaces or elements may be installed within the lips which serve to guide and limit the movement of t...

A method and device for the comparison of patterns, and especially of fingerprints, making possible the identification of a given person. The device comprises means for projecting an incoherent image of the finger to be compared onto a permanent fingerprint record, oscillating same with respect to each other, projecting the resulting image onto a photocell and ascertaining the A.C.-current characteristics of the resulting electrical signal. When the finger is positioned exactly, oscillation in o...

In the art of investment casting, a refractory mold characterized by a casting system including a sprue passage, a cup at one end of the sprue passage, a runner extending from the cup and connecting to the sprue passage near its other end, at least one pattern cavity gated into the sprue passage between the ends of the runner, and a refractory wall in the cup dividing it into a pouring cup portion communicating with the runner and another portion communicating with the sprue passage. A pattern s...

Pattern forming apparatus and methods for grouping food products, such as loaves of bread, into any one of a plurality of different patterns wherein an approach conveyor, for successively conveying products in a longitudinal path, communicates with a reorienting member for receiving a first group of products from the approach conveyor and disposing them in end-for-end reversed position relative to incoming products on the approach conveyor. Pusher mechanism is provided for selectively, transvers...

A permanent type non-expendable pattern for making refractory molds in which portions of the pattern are retractable from a projected position in which they are disposed in the cavity to be filled with the refractory molding material and a retracted position in clearance relationship relative to the refractory mold material, enabling an extraction of the pattern from the refractory mold produced. The retractable pattern sections, when in the projected position, are locked in accurate registratio...
