Abstract: Curcumin is employed for the purpose of detecting and warning of the presence of cyanide in a food, drug, or other oral composition. The curcumin is incorporated into a food packaging material. In the presence of cyanide, the curcumin undergoes a color change causing at least a portion of the packaging material to manifest a color change. The color change is sufficient to be detected by an observer, thereby providing a warning of cyanide adulteration of the product.

Abstract: An applicator tool for use in applying an insulating strip on the surface of a window pane used in the assembly of multi-pane windows. The applicator tool includes a directing roller which directs the insulating strip onto the glass while maintaining only rolling contact with the surface of the glass. The directing roller is removable, is capable of adjustment in the vertical direction, and is capable of adjustment to vary the distance from the edge of the glass the insulating strip is placed. The applicator further includes two guiding rollers which maintain rolling contact with the edge of the glass. Transport rollers may be used on the applicator tool when insulating strip is applied to glass located on a flat surface. The tool also includes a rectangular block for use in molding the insulating strip around a corner.

Abstract: A protective backing for composite sheets and a method of detecting the presence of protective backing within a stack of composite sheets. The protection of the surfaces of uncured composite sheets is provided by applying a protecting backing having a metal component to the composite sheet, which is removed prior to layup and curing of a composite laminate. Presence of the protective backing in a layup of composite sheets or a laminate made from the layup composite sheets may be detected by passing them through a sensing presence of an eddy current.

Abstract: A process and nylon release sheet for manufacturing printed circuit boards from epoxy prepregs is disclosed. In such process layers of the prepregs are separated from one another by a release sheet. The release sheet comprises an aliphatic or aromatic nylon or nylon copolymer which is a condensation product of a dicarboxylic acid and a diamine. The nylon film contains a heat stabilizer and an inorganic particulate antiblock additive, e.g. diatomaceous earth, glass beads, amorphous silica, talc, mica and molybdenum disulphide. The nylon may be toughened by the addition of a phosphorus-containing catalyst or an epoxide.

The pressing of the transfer sheet against the substrate is carried out with a press tool devoid of surface pattern and having a generally flat press surface.

Abstract: A labelling machine for bottles or the like includes several stations located behind one another along a track. The stations include an adhesive application station, a label feed station and a label transfer station. There are three extracting elements which are each mounted to rotate on a rotating support to be moved past the stations during each rotation of the support. Each extracting element has an outwardly-curved receptacle surface for the label which rolls along the stations. The drive for each extracting element is a cam drive, which comprises common, stationary double cam discs for all the extracting elements with two cams located on one side in two planes with one above and at some distance from the other. Two sets of followers are mounted on a bearing shaft which is coupled with the rotating support. By means of a form-fit with the two cams, the followers provide positive movement of each extracting element over its entire revolution when the support rotates.

Abstract: A device for the application of labels to packages, such as cigarette packs. Each label is applied to one or more faces or end portions of the pack. The application of the comparatively small labels to the packs can impair the performance of a packaging machine. According, the present mechanism continuously transfers the labels to packs, during the continuous transportation of each pack between two processing station by a label conveyor. The conveyor includes several label holders, each of which has a pocket to retain a package within. As the conveyor rotates between stations, the package is shifted within the pocket, and is forced through a label holder. The label holder, retains a label in a position perpendicular to the direction in which the package is moved. Thus as the package is forced through the label holder the label adheres to the package. In this manner, label application is achieved in a continuous process.

Abstract: Insulating equipment (100) includes a flexible arm (1) having at one of its ends a means for attachment to a pole and at the other end means for attaching an electric line substantially perpendicular to the arm (1). The thickness of the arm (1) decreases regularly from the means of attachment to the pole toward the means of attachment to the electric line, while the height of the cross section of the arm is constant. The arm (1) has in the direction of its thickness a series of layers (7a, 7b, 7c, 7d) of continuous mineral fibers extending in the direction of the arm's length and separated by layers (8a, 8b, 8c, 8d) of randomly-oriented short mineral fibers. These layers are bonded by a synthetic resin in which a layer (9a, 9b) of fabric of mineral fibers may be placed on each side of the arm (1) between the first layer of short fibers and the following layer of continuous fibers. To be used for improving longitudinal flexibility and resistance to vertical loads.

Abstract: A system for fusion bonding several attachments to a relatively large and bulky thermoplastic article employs means for fixedly securing the article, and a movable fixture selectively positionable relative to the thermoplastic article. The fixture includes a base plate held stationary during bonding operations, a gripping device supporting the thermoplastic article and longitudinally reciprocable relative to the base plate, and a pair of arms supporting a platen or other heating tool, also longitudinally reciprocable relative to the base plate. The tool supporting arms further can be pivoted to move the heating tool between an aligned position between the thermoplastic attachment and fixed thermoplastic article, and a remote, withdrawn position, to allow longitudinal movement of the attachment into engagement with the thermoplastic article, following use of the heating tool to simultaneously fuse selected surface portions of the thermoplastic article and attachment.

Abstract: This invention relates to a labelling machine for objects, in particular bottles, with several stations located one behind another along a track, namely an adhesive application station, a label feed station and a label transfer station. At least one extracting element is mounted so that it can rotate on a rotating support. The extracting element has an outwardly curved receptacle surface for the label which rolls past the individual stations when the support rotates. The drive mechanisms of each extracting element comprises a cam transmission mechanism. The cam transmission mechanism comprises two cams located one above the other. The cams have the basic shape of ovals indented on both long sides and are oriented crossways to one another. A plurality of followers engage with the outside curves of the cams. The followers are offset from one another by an angle not equal to 90 degrees and have lever arms of different lengths.

Abstract: By compressing and heat curing a non-resilient, non-flexible recurable material formed by subjecting cured polyimide foam to the action of pressurized steam, a wide variety of useful articles may be produced. These include tough, flame-resistant plastic films, sheets, panels, boards, and shapes in general; composites (both reinforced and unreinforced); and laminates and other articles in which separate shapes or parts are bonded together by a new type of tough, flame-resistant adhesive. Additionally, heretofore worthless products such as the kerf cut away from buns of polyimide foam during the foam manufacturing process can be converted and vastly upgraded into any of such an array of new articles of manufacture such as those just mentioned.
