  • Patent number: 4312686
    Abstract: Distortions during printing and laminating are minimized by printing the design on a stable base, preferably release paper, and then transferring the printed design to a hot plastic web made continuously by an extruder. A stress relieved hot plastic film is then laminated to the printed web to provide a protective wear coat. To emboss in register with the printed design, the laminated product is first aligned by means of registration marks that are printed along with the design. Embossing is then made using a conventional engraved roll having raised sections which are images of the printed design. After embossing, the web is partially cooled and annealed. It is then aligned with a die cutter using the same registration marks as used for alignment during embossing. As a result, individual tiles can be cut automatically in register to the printed and embossed pattern.

  • Patent number: 4290471
    Abstract: In a built-up core for the bead of a pneumatic tire, the wires (A,B,C) of each lay (8) of the built-up core (4) are of a trapezoidal cross section. Between the wires (A,B,C) of each lay (8) of wire and the wires (A,B,C) of the next, overlying lay (8) of wire, there are wedge-shaped clearances (9). As a result, the wires (A,B,C) of each lay (8) of wire find a support on the edges of the wire of the underlying lay of wires so that they cannot be displaced against each other during the production of the tire.

  • Patent number: 4289568
    Abstract: A machine for applying particularly configured pieces of thermally-activated tape to a heated substrate, such as a continuous strip of lead frames, it is capable of long term, high speed operation without becoming fouled with tape pieces or residual adhesive. A drop-through die assembly to blank the tape pieces is mounted for reciprocal movement to and from the metal strip normally supported in spaced relation beneath the assembly. Cooling fluid is circulated through the die and stripper plate of the die assembly for dissipating heat generated in the punch during the blanking operation. This cooling feature together with the normally spaced arrangement of the die assembly and the heated substrate, serves to maintain the temperature of the punch well below the activating temperature of the tape, whereby the tendency of the punch to collect a build-up of adhesive and tape pieces is virtually eliminated.

  • Patent number: 4289559
    Abstract: A process and apparatus for heat laminating a light gauge plastic film to a heavier substrate material. The film and substrate are fed between rotating laminating rolls, one of which is heated, the rolls being urged against each other under pressure. Prior to lamination, the substrate is positioned on a supporting surface of hard, flexible material in the form of an endless belt or sheet which passes between the rolls, or a smooth flexible sleeve secured to one of the laminating rolls. During lamination, the substrate adheres to the flexible supporting surface, and the substrate is maintained in engagement therewith for a predetermined time after lamination to permit the same to cool and stabilize in order to prevent the formation of ripples therein. The film may have a decorative coating applied to one face thereof, which is transferred to the substrate at the time of lamination and the film may be optionally peeled off the substrate leaving only the decorative coating applied to the substrate.

  • Patent number: 4286645
    Abstract: The reinforcement of a pneumatic tire comprises, proceeding in a direction from the inside towards the outside of the tire, a carcass reinforcement continuous from bead to bead and three superimposed plies of cords limited to the region of the tread. In the sidewalls of the tire, the cords of the carcass reinforcement form a substantially constant angle with the circumferential direction of the tire of between and In the tread region of the tire, the cords of the carcass reinforcement form an angle with the circumferential direction of the tire which is smaller than the angle made by those cords in the sidewalls. The cords of the three tread plies form acute angles .alpha., .beta., and .gamma., respectively, with the circumferential direction, and the cord angle .alpha. of the one of the three tread plies nearest the carcass reinforcement and the cord angles .beta. and .gamma.

  • Patent number: 4284117
    Abstract: A steel belted radial ply tire construction characterized by an improved cap ply is disclosed. In the finished tire, a cap ply is formed from at least one layer of rubberized yarns of synthetic filamentary textile material. The cap ply is disposed in direct surrounding relation to the radially outermost belt ply of the tire. Since the cap ply is formed from single yarns rather than cords, the cap ply is thinner than conventional cap plies, has superior flexibility and heat dissipation characteristics. This abstract is not to be taken either as a complete exposition or a limitation of the present invention, the full nature and extent of the invention being discernable only by reference to and from the entire disclosure.

  • Patent number: 4284457
    Abstract: Described herein is a method for bonding a skin member such as metal, plastic, perforated acoustic skin, or fiberglass or graphite reinforced plastic, to a honeycomb core support structure such as lightweight hollow hexagonally shaped tubes. Such a method can be used in the construction industry for making panels and walls and similar structures, and in the aerospace industry for making airplane and satellite structures, etc. The adhesive employed is an adhesive-coated fabric material which is partially cured onto the honeycomb and cooled down, following which most of the adhesive material is removed when the coated fabric is peeled away. This leaves an optimum amount of adhesive in the most effective locations on the wall edges of the honeycomb cells where it is needed for bonding the core to the skin. The skin member is then bonded to the honeycomb by bringing the adhesive to its final cure.

  • Patent number: 4284446
    Abstract: A device for obtaining a culture sample from a particular location in a body passage while avoiding contamination of the sample by materials located elsewhere in the body passage includes a stiff flexible tube. A sleeve of pliant waterproof material surrounds the tube and the distal end of the sleeve is tucked into the distal end of the tube. A bag of pliant waterproof material is bonded to the outside surface of the sleeve to form a waterproof seal extending all around the sleeve, the bag enclosing the distal end of the tube and the distal end of the sleeve. The bag has a limited burst strength and is broken after the distal end has been emplaced at a particular pre-sampling level to expose the sterile sleeve that was tucked into the tube. As the tube is inserted a short distance further, the portion of the sleeve that was tucked into the tube everts out of the distal end of the tube to form a sterile curtain surrounding the distal end of the tube and protecting it from contamination.

  • Patent number: 4281791
    Abstract: A motor vehicle traction aid device including a plastic bag containing a sand mixture for insertion under a tire on a drive wheel of a motor vehicle for improving traction on ice, snow or the like. The bag is partially filled with the sand material and includes a foam or sponge rubber tab on one side. The bag is inserted between the driving surface and the tire of the motor vehicle such that the tab engages the tire. Rotation of the wheel toward the driving surface causes the tire to engage the tab, drawing the bag and the sand material under the tire in a rolling action, bursting the bag and dispensing the sand beneath the tire.
