Abstract: Textile yarns or strands are heated, as by contact with hot rolls, and then are crimped, preferably compressively as in a stuffer crimper, after being drawn to increased length if so drawable.

Abstract: Package winding of textile strands uninterrupted by transfer from a full to an empty package is accomplished by delaying lateral transfer of the winding strand from a full to an empty package and by picking up a resulting transfer tail of the laterally transferring strand adjacent the end of the empty package. The transfer delay step utilizes a bistable inertial device located to intercept the laterally transferring strand and to be repositioned thereby and to release the strand after momentary inertia-induced delay during which the strand begins to wind onto the empty package. The pickup step utilizes rotary devices located at the spaced adjacent ends of spindles for the respective packages, such device on the spindle of the package to which the strand is transferring being adapted to engage and grip it. The strand is broken or otherwise severed between the pickup device and the full package, thereby enabling the strand to be traversed onto the empty package.

Abstract: Textile yarns or strands are drawn and crimped under controlled conditions of tension, speed, and temperature, at both input and output stages, with resulting beneficial effects upon the resulting product, by specified apparatus.

Abstract: A pen for use in recording instruments includes integral hinged member which folds over and locks in place on a pen arm and thus facilitates attachment of pen and pen arm. Preferably, integrally molded ribs are included to press into and to better secure the pen arm upon locking engagement of the hinged member.

Abstract: Textile strands are crimped by feeding them into and forwarding them within a laterally confining region that terminates in a laterally surrounding fine screen with a flared outlet end. The resulting strand-crimping apparatus of stuffer-crimper type utilizes flow of injected fluid to forward or assist in forwarding the crimped strand therethrough.

Abstract: Cornerboard protector comprises laminated cardboard or paperboard with embedded reinforcement strip, which is bent at a right angle along its length, the reinforcement strip being embedded only in the unbent portion of the strip. A V-cut in the bent portion and extending into the unbent portion with its apex terminated just short of the reinforcement strip provides a mitered corner about which the laminate is folded to form a neat and strong corner protector.

Abstract: An improved mooring buoy is provided having means for maintaining the shackle at the upper end of its hawser above water level when the buoy is at rest in the water. The buoy is provided with a floating body having a generally vertical passage extending therethrough. The lower end of the hawser is shackled to a weighted line, such as a chain, which is connected to a dead weight. Both the weighted line and the hawser are slidable freely through the passage relative to the floating body of the buoy. Means are provided for limiting the downward sliding movement of the hawser relative of the floating body, to thereby maintain the upper end of the hawser above the water level. The buoy also may be provided with a skirt extending below the floating body to a depth sufficient to terminate below the usual level of the ship's propeller, to prevent the propeller from becoming entangled in the submerged weighted line.

Abstract: A roll pelletizer as disclosed and claimed in U.S. Patent Number 3,561,051 with rolls consisting of a helically wound strip of resilient material having a reduced depth portion along its length providing grooves in adjacent wraps of the strip, the remaining non-reduced depth portion of the strip defining lands. Opposed compressive rolls of this invention are helically wound with opposite hands so that lands of one roll intermesh or mate with grooves of an opposed roll. In preferred forms of this invention, a thin, non-yieldable (generally metal) strip is helically wound on a cylindrical base member with the helically wound resilient strip interposed between adjacent wraps thereof. The non-yieldable strip may include right angle tabs spaced at intervals along the length thereof which mate with spaces provided therefor in the grooved portions of the resilient strip.

Abstract: A knitting machine is provided having one or more needles for knitting from one or more strands a variety of cord-like structures formed of one or more wales of knitted stitches. The machine is particularly useful for the manufacture of knitted yarns, either from strands of continuous or spun filaments or from a roving or sliver of staple fibers.

Abstract: The present invention concerns a new vise intended to be mounted on bias-cutting sawing machines, i.e., on circular saw machines for miter cutting metallic sections, utilizing pivotal movement of the saw and the holding device for the work piece. The holding device is supported by a pivotal frame movable about the vertical diametral axis of the saw. The invention is characterized by the fact that it provides means for the contact surfaces or jaw caps of the work holding device always to remain parallel to the axis of the work piece, regardless of the angle of orientation of the saw with respect to the work piece, such means being designed with the saw blade always passing as close as possible to the jaws of the vise.

Abstract: An automatic device for systematically placing elongated products, such as pieces of sectional iron, bars, or the like, on a roller conveyor, said device having a scraper remote from the conveyor for providing storage for a plurality of such elongated products, a pusher for advancing the products from storage in a direction transverse to their longitudinal axes to a feeding device, said feeding device having its longitudinal axis parallel to the axes of the rollers of the roller conveyor, means for depositing the elongated products on the feeding device one at a time, at uniformly spaced intervals, to provide on the feeding device a layer of elongated products disposed in uniformly spaced, parallel relation, means for advancing transversely the layer of elongated products on the feeding device to the roller conveyor and means automatically operative for delivering the elongated products, in selected quantities, from the feeding device to the roller conveyor.
