Abstract: A machine having blanking, barb forming and bending stations is provided for making a coil of metal tape from a substantially planar linear strip of metal stock wherein such strip is fed in sequence to the stations in a single pass through the machine to respectively edge notch the strip into barbs, upset the barbs into inclined relation to the plane of the strip and then edge bend the strip in the plane of the strip to form it into identically angularly displaced adjoining linear segments of equal length to make a generally annular coil of barbed metal tape.The method of this invention features forming spaced openings along a longitudinal axis of a substantially planar linear strip of metal stock, positioning the strip by means of its openings and edge bending the strip in the plane of the strip adjacent its openings to form the strip into a coil having identical angularly displaced adjoining linear segments.

Abstract: A lift truck mast having extensible uprights received one within the other. Each upright includes a pair of rail members each of which has a web and flanges such that the members are I-shaped in cross section. The rail members are nested together with the web portion and end flanges of the inner overlapping the web portions and end flanges of the outer. The web portions of one rail member carry rollers which ride on the rear end flanges of the adjacent nested rail member. Each web portion, when viewed in cross section, provides a straight section of uniform thickness and a tapered portion gradually increasing in thickness toward the rear end flange. The rollers are spaced from, but mounted parallel to, the straight web portions so as to rotatably engage the rear end flanges and tangentially contact the tapered web portion. Forward mast bending loads are taken radially by the rollers and side thrust loads parallel to their axes of rotation for improved anti-friction properties and longer wear.

Abstract: A pressure vessel such as a steam cooker has a novel variably sloped cam arrangement for sealing a warped access door against the inside of an access opening. Such access openings are typically of circular configuration, and the access doors are warped about one axis for insertion therethrough. The latching mechanism of this invention enables the door to be swung from an open position into a first position inside the pressure vessel and then to be moved rapidly into a second position in engagement with an inside rim of the access opening. This rapid movement is accomplished by rotation of an operating handle through a relatively small angle. Thereafter continued rotation of the handle stresses the access door, removing the warp therefrom and sealing the door against the inside rim of the access opening. The latter door stressing rotation produces relatively little motion of the door for a relatively large angular rotation of the operating handle.

Abstract: A laminated tubular connector for splicing or terminating electric conductors, comprising an outer layer of a heat shrinkable dielectric material, e.g., polyethylene terephthalate, and an inner layer of a relatively soft, self-adhesive, low temperature flowable thermoplastic material, preferably a polyvinyl acetate composition. When heat is applied to the connector, the outer layer shrinks and the inner layer functions as a sealant and a cushioning agent. The adhesiveness of the inner layer may be used to hold the connector in place during subsequent operations by pinching the connector so that the depressed portions of the tube adhere to each other prior to heating the connector to shrink the outer layer.

Abstract: Sweet, non-crystallizing (at concentrations of 75% solids or above) syrups are prepared having the following saccharide composition: dextrose, from 20% to 40% levulose, from 20% to 40%; maltulose, from 10% to 60%; total ketose composition (principally levulose and maltulose), 40% to 80% (percentages by weight dry basis). Optionally, the syrups may contain up to 25% maltose and/or up to 20% higher saccharides (i.e. having degrees of polymerization of greater than 2). The syrups are prepared by first subjecting a starch hydrolyzate, containing at least 40% maltose and not more than 5% dextrose, to an alkaline isomerization treatment to isomerize a portion of the maltose to maltulose, the isomerization being conducted until the resulting hydrolyzate contains between 10% and 60% maltulose. The resulting product is then treated with glucoamylase to saccharify at least a portion of the remaining maltose (as well as higher saccharides, if present) to dextrose.

Abstract: A status-indicating system is disclosed, directed specifically to provide information for regulating credit transactions and the like. An inquiry station includes structure for providing signals that identify a subject and also indicate whether or not the contemplated transaction suggests caution, e.g., cash will be returned on a check. The inquiry signals are transmitted to a primary register which has a location assigned for each subject and which locations record first signals (indicating that the subject is or is not authorized) and second signals (indicating the subject is or is not in question). The questionable status results from a relatively recent inquiry by a subject which involved a transaction of the type suggesting caution. Thus, such transactions result in the recording of the second signals, in the primary register.

Abstract: A device for attaching a variety of various eye shields or spectacles, safety shields or the like to a cap which allows for variable adjustment in the location of the spectacles with respect to the cap, removeable attachment, and two position up-down positioning of the eye shield comprising one or more wire frames which are attached by upper and lower velcro strips to a cap visor, the frame having a pair of clips which attach the eye shield or spectacle to the frame. Each frame is formed from a light weight unitary wire that allows for frictionally holding the eye shield in an up or down position relative to the wearer and wearer's vision. The base of the frame is removeably attached to the cap by a fabric fastener such as velcro which is attached in layers to the lower side of the visor and by an additional strip that goes over the base of the frame. A variety of eye shields, lenses, sunglasses, or the like can be readily detached or interchanged with each frame or frames.

Abstract: A one-piece disposable coverall garment for use by toddlers during mealtime is disclosed. The one-piece coverall garment includes loosely fitting blouse and trousers sections which are padded with an absorbent material to prevent exposure of the toddler's clothing to spilled food and drink. The blouse section is characterized by an oval neck opening and a deep back opening along the middle of the back to the waist. The neck and back openings have a common border section formed by a drawstring fastener. The neck and back openings are opened and closed simultaneously by the drawstring fastener, and when the drawstring fastener is untied, the blouse portions forming the border of the neck and back openings can be widely separated thereby defining, in combination, a large, step-in opening.
