Abstract: A method for resurfacing a bowling alley to fill dents and overlie the original wood surface with an oil barrier layer over which is adhesively affixed a high pressure laminate material layer with an external surface having the appearance of the original surface of the alley.

Abstract: A photographic album page comprising a fibrous centrally disposed lamina and a pair of overlying clear synthetic resinous laminae. Pockets are formed by ultrasonic sealing of the clear laminae together through the fibrous lamina which disintegrates under the generated heat of sealing. The pockets are thus formed as a continuous sealing operation at the same time the page is laminated by sealing in broken lines, whereby the fibrous lamina retains its structural integrity.

Abstract: Apparatus for applying a weldable web or band of synthetic plastic material to a package on a table has a feeding device which advances the web from a source into the channel of a mobile loop forming device loosely surrounding the package. The feeding device is arrested when the web is looped around the package so that the end portions of the resulting loop overlap. The loop forming device is then removed and the web is moved rearwardly so that the loop snugly surrounds the package. In the next step, the web is severed between the outer overlapping portion of the loop and the source, and the severing device is withdrawn so that the sonotrode of an ultrasonic welding unit can bond the outer portion of the loop to the adjacent inner portion all the way to the cut where the outer portion was severed from the source.

Abstract: Method for labeling objects including fruits supplied to a labeling station by an endless conveyor. Labels on a carrier tape are moved from a supply reel by a knurled roller which impresses a surface weakening pattern on each label so it will readily conform to a non-planar surface of the object. The tape is formed into a feed storage loop by an oscillatable tension regulating arm which controls actuation and deactuation of the knurled roller. An indexing tape segment passes through an indexing block in a transfer station, where each entering label is sensed by a detector. Indexing movement of the tape is initiated by an object detector on the conveyor. Indexing moves the tape around a sharp bend to strip the detected label from the tape and position it in a label holding frame.

Abstract: Extension ladders constructed of pultruded fibreglass reinforced plastic for use in an high voltage electrical environment are improved when they do not have any metal components within the field of the induced electrical currents and to achieve the junction between the fibreglass reinforced plastic rungs requires separate molded fibreglass reinforced plastic external sleeves so adhesively bonded to the stiles and the pultruded hollow rungs to make the junction and also such sleeves are not to have any projections outside the outer boundaries of the stiles.

Abstract: Means for improving the traction of wheeled equipment used in the logging industry comprising an improved skidder ring with clevises to which the connecting tag chains are fastened by a pin preferably secured in place by a spot of welding material. When a tag chain breaks and must be replaced, the pin is severed by a torch permitting the remaining two pin parts to be removed from the clevis. The end link of the replacement or repaired tag chain is secured by a new pin placed in the clevis. A spot of welding material is applied to the pin to hold it in place.

Abstract: A method of sealing a tube of flexible thermoplastics material by welding in which opposite sides of the tube are pressed flat between two jaws. The flattened tube thus has two opposed flat walls which have inner faces in contact, and these flat walls are connected at two opposite edges by folds caused by the flattening of the tube. The jaws are maintained a fixed distance apart, and one is rapidly reciprocated along its longitudinal direction by a vibrator, relatively to the other jaw. This causes the contacting flat walls to rub and become so heated by friction that the contacting plastics faces melt. These molten areas unite in a weld when reciprocation of the jaw is stopped and the plastics cools.

Abstract: Shaped and self-supporting stratiform laminates, such as inner door panels for automobiles, are produced from a thermoplastic substrate and a flexible sheet material in a one-stroke molding, laminating, and cutting operation; laminated products obtained have protruding free edge portions of the flexible coating sheet so that cut edge portions of substrate can be covered subsequently with the protruding free portions.Apparatus for producing such laminates is a molding press having two molding plates, each of which includes one component of a pair of cutting means; the other two components of the pair of cutting means are provided by a generally annular element that is movable relative to the molding plates; the annular element includes a surface for cooperation with a peripheral knife around the surface of the upper molding plate to form one cutting means, and a cutting edge for cooperation with a shearing edge of the lower molding plate to form the second cutting means.

Abstract: A laminate of insulating material having fine metallic articles dispersed therein is rendered highly conductive by passing electrical energy through the laminate of sufficient strength to break down the dielectric resistance of the insulating material at the points of contact of the metallic articles.

Abstract: Luffas are subject to disintegration into fibers which are carded and needled to a textile support. The resulting product is impregnated with a synthetic resin, dried and calendared to produce a foil from which, for example, inner soles can be cut or stamped.

Abstract: A method of affecting the tail end of a roll of plastic film to render it readily identifiable and easy to grasp and start without tearing the film web into strips. The tail end of the film is embossed on-line as it is separated and about to be wound up on a roll core. The method is accomplished by securing the tail end between a heated surface on the upstream side of a knife on a cut-off roll and a lifting and embossment mechanism to provide a wide embossment across the tail end of the film at about the time it is severed from the film stock. The method produces a novel puckered tail, particularly for highly oriented films where tension is relieved while the tail end is still heated.

Abstract: A method and a machine for producing a latticework structure composed of cells of essentially parallelepipedon shape from e.g. paper coated on one side with synthetic resin. The web is formed over a mandrel into a sleeve of square cross-sectional shape while being successively advanced, and the sleeve is cut into bits which are flattened and by a step-by-step feeding mechanism positioned adjacent one another with one bit overlapping the following one over halfway in the transverse direction. The bits are bonded together while so positioned whereby flat elements are formed. These flat elements are stacked on top of one another by a mechanism ensuring that the elements are displaced by one cell width in their longitudinal direction and the stack of elements is then cut into pieces having the desired height of the cells. When extended, these pieces form the desired cellular latticework structure.

Abstract: An anvil having a working end away from a mounting shank, has compressed air flowing through the anvil to feed outward to the working end. An insert fastened to a panel is secured to the panel by forming on one end of the insert and by bonding with an adhesive on the other end. The working end of the anvil presses against the insert during forming and the flowing compressed air blows excess adhesive from the contacted surface of the insert.

Abstract: Apparatus for applying tape to a paved surface to form markings on the surface, said apparatus being supported for movement along the paved surface by wheel means including at least one roller, and further including tape support means for rotatably supporting a roll of tape; tape guide means positioned above a leading edge of the roller; tape advance means for advancing tape that extends from the roll of tape over the tape guide means into position for the roller to press the tape against the paved surface; and cutting means for cutting the tape while it extends under tension from the roller to the tape guide means.

Abstract: The side connector in a nonskid tire chain of this invention improves the invention of the herein identified copending application by providing spaced apart transverse bars, one carried by a bar-receiving member having an opening therein and the other by a bar-shaped member of substantial length slidable in the slot. Such construction provides supports for detachable elastic means extending between the transverse bars and relatively yieldingly urging the bar-receiving and bar-shaped members toward retracted position. One of the spaced bars extends between the walls of the bar-receiving member and the other projects on both sides of the bar-shaped member. The detachable elastic has a longitudinal slot so that an end portion can span each of the projections of the bar carried by the bar-shaped member and the other end portion can span the bar carried by the bar-receiving member.

Abstract: Alphabetic labelling of articles includes the use of a label having on a portion of its face a first set of indicia and on another portion of its face a second set of indicia which relate to the same subject matter as the first set. The second set of indicia is oriented in reverse and upside down relative to the first set. A machine readable code unique to the subject matter of the sets of indicia is located on one of the face portions of the label. The label when folded about its length isolates the two fields and on application to an article, provides visual identification of the article from two of its sides. The label may be provided with a machine readable indicia code which is representative of at least one indicium of either of the sets. An article labelling system may be adapted to read the indicia code and apply as controlled by the reading operation, one or more labels having letters corresponding to the coded indicia.

Abstract: A method and apparatus for dispensing adhesive-backed foil having a protective covering in contact with the adhesive surface. A spool is mounted on a frame to provide a continuous strip of foil to a guide roller having a circumferential groove for receiving and guiding the strip of foil, the groove being approximately the same width as the width of the foil strip. A peel blade incorporates a peel edge contacting the foil between the pressure-sensitive adhesive surface and the protective covering to force the protective covering out of contact with the adhesive surface; the peel blade is mounted to place the peel edge in contact with the foil strip at the guide roller surface. A workpiece, such as a flat decorative glass configuration, is placed with its edge in contact with the adhesive surface of the foil on the guide roller. A workpiece guide is mounted adjacent the guide roller for contacting the workpiece to maintain the edges of the workpiece centered in the circumferential groove of the guide roller.

Abstract: A paperboard web is severed transversely between the double facer machine and the slitter-scorer after the completion of a production order. The speed of the double facer machine is maintained constant while the severed web section is accelerated to a speed substantially above the speed of the double facer machine to create a gap. Adjustments to one or more of the slitter-scorer and cut-off for the next production order are made while the same are in the gap. Sheets cut from the web section are shingled on a shingling conveyor. The speed of the shingling conveyor is accelerated prior to the arrival of the last sheet of the web section and decelerated while the gap is on the shingling conveyor.
