Abstract: A pressure switch and method of manufacture wherein a resiliently yieldable intermediate open layer is sandwiched between flexible conductive layers, all of which is enclosed between flexible outer layers, so that in the unstressed or relatively unstressed condition the contact layers are spaced apart by the intermediate layer, while flexure or other sufficient stressing of the assembly effects contact of the contact layers through the open intermediate layer.

Abstract: Method and apparatus for assembling for reprinting a plurality of film strip portions into a continuous film strip by adhesively affixing the film strip portions to a film carrier comprising a paper tape to which has been joined an adhesive tape along one edge to form an adhesive stripe along that edge. The carrier cooperates with a film gate including an indexing edge for aligning the film strip portions for subsequent adhesive fixing to the edge of the carrier. Alternate embodiments for the film gate indexing structure for different size film are disclosed. The film carrier is marked with printing instructions for some or all of the individual negatives affixed thereto.

Abstract: A web with overlays for use in the document presentation device of a photographic copying machine has several sheet-like sections with overlapping portions which are separably coupled to each other by snap fasteners and carry overlays which are welded thereto by the application of heat and pressure. The overlays are applied to those sides of the sections which are coated with layers of photographic emulsion.

Abstract: Carpeting especially suitable for use in areas subjected to heavy wear or abrasive weather includes a plurality of cured, rubber-based strips with filaments embedded in and projecting upwardly from them forming a pile on their upper surfaces. The strips lie side-to-side, and each is bonded along its bottom surface only to a vulcanized, rubber-based sheet that does not project substantially into the spaces between the elements. Apparatus and a method for making the carpeting are also disclosed.

Abstract: A method wherein a machine-foldable wrapper for chewing gum has a paper substrate metallized to give the appearance of continuous foil, the foil being made discontinuous to allow the paper to reach and maintain a moisture content which is in equilibrium with the ambient air. This prevents the wrapper from curling at the edges while in storage.

Abstract: Apparatus for applying leading tips to a continuous sheet material and then cutting the same comprises a rotatable cut drum, a cutting knife contained in the cut drum and adapted to be caused to project outwardly through the surface of said cut drum at a fixed position while said knife is rotating together with the cut drum, a cam mechanism secured to a stationary member outside the cut drum for actuating said cutting knife, a single position clutch adapted to be rotated in synchronism with the cut drum, a mechanism adapted to be driven through said single position clutch for applying leading tips to the continuous sheet material, the arrangement being such that the continuous sheet material is fed along said leading tip applying mechanism and the outer periphery of the cut drum as the cut drum is rotated and that said single position clutch is energized into its connectible condition at predetermined time during the operation, while said cam mechanism is switched to a cammable condition in which it is able t

Abstract: A method for making irrigation conduits comprises the steps of perforating a first sheet of plastic film by repetitively forming rows of holes in the cross-machine direction, positioning a fabric strip over the holes, positioning a second sheet of plastic film under the first, sealing the fabric strips and the sheets of plastic film together by forming a plurality of fused seals running in the machine direction, and slitting the seals lengthwise to separate the resulting conduits.

Abstract: A preconsolidated tape of continuous, high strength filaments in a metal matrix is coated with a layer of adhesive polymer and cut into shaped plies. The coated plies are stacked in a mold and resin bonded together by the application of heat and pressure. Many of the desirable physical properties of a diffusion bonded metal matrix article are also found in the resin bonded metal matrix article of the subject invention. Also, the use of preconsolidated adhesive coated plies eliminates the need for high diffusion bonding pressures and temperatures, thereby cutting the time involved for the bonding and molding operation by a factor of 8 in some instances.

Abstract: Disclosed is an apparatus and method for automatically aligning and bonding a preperforated flexible repair tape to the side edge portion of an elongated strip, such as motion picture film, having damaged sprocket feed hole perforations located therealong. Film to be repaired is fed continuously from a supply reel through a pair of straightening and flattening rollers to a repair station comprising a pressure roller cooperating with a sprocket roller to automatically and precisely align the preformed feed holes of the tape with the damaged feed hole locations of the film and to bond the tape and film together in the aligned condition. From the repair station, the laminated tape and film pass through a pair of cooperating rollers to more firmly bond the tape and film preparatory to collection on a take-up reel.

Abstract: A machine for continuously laminating a flexible film onto a succession of glass substrates is disclosed. The machine comprises a conveyor, adapted to transport a succession of glass substrates along a horizontal plane toward substrate preparation means which wash one surface of each substrate. The machine further includes guide means for safely guiding and alignably transporting the succession of glass substrates from the substrate preparation means to a predetermined application line associated with application means. The application means are adapted to continuously unroll and expose a quantity of flexible film having a pressure sensitive adhesive surface at the predetermined application line which lies in the horizontal plane, whereby film is continuously laminated onto the surface of each successive glass substrate to produce sheets of shatter-proof glass.

Abstract: A method and an apparatus for affixing labels to a web of sheet or film material by means of a cylindrical labelling device having a label arranged peripherally thereon, said label being affixed to the web with a pure rolling motion and compressive action.
