  • Patent number: 4102722
    Abstract: A method of making transparent electroconductive window comprising an assembly element supporting a circuit portion electrically coupled to a novel self-soldering bus bar consisting essentially of particles of a finely divided highly electroconductive metal, such as silver, dispersed within a metal alloy having a fusion point between about and about C. A mixture of finely divided metal and of said alloy is applied to an assembly element along one or more lines in electrical contact with an electroconductive heating element carried by said assembly element. The one assembly element is assembled with other assembly elements to form a sandwich that is laminated at a temperature higher than the fusion point of the metal alloy to form a transparent electroconductive window having highly conductive, self-soldering bus bars formed along said lines.

  • Patent number: 4101358
    Abstract: Methods of making network structures include forming on one side of a sheet of thermoplastic polymer a plurality of parallel continuous main ribs and forming on the other side of the sheet in a different direction a plurality of parallel discontinuous tie ribs. The tie ribs are discontinuous in the areas where they cross over the main ribs to eliminate any increased thickness at the cross-over points of the main ribs and tie ribs. The ribbed sheet thus formed is drawn in either one direction or in two preferably perpendicular directions to open the sheet into a network structure and to orient the main ribs and preferably also to orient the tie ribs.

  • Patent number: 4101370
    Abstract: Tread plates on mutually opposed endless belts clamp and move a pack of boards horizontally lengthwise between electrodes for setting adhesive between the boards by dielectric heating. The tread plates are engaged by backing members spaced transversely of the length of the belt, and the tread plates are connected by a chain located between the backing members. The portions of the tread plates engageable with a surface of the board pack are of a suitable plastic to deter passage of radio-frequency energy from an electrode to an electrically-grounded portion of a tread plate or to the chain. Air bags are inflatable to press at least one endless belt against the board pack or to move such belt relative to supporting means away from the board pack. Adjusting means for prepressing rollers ahead of the endless tread belts on one side of the board pack and adjusting means for the endless tread belt on the same side of the board pack are interconnected for synchronized adjustment.

  • Patent number: 4097322
    Abstract: In the manufacture of a rigid elongate member of resin bonded reinforcing elements, e.g. a resin bonded glass fibre rod, reinforcing elements are passed through an apertured guide and are secured to one of two hook means spaced one vertically above the other. Elongate loops of the reinforcing elements are formed by effecting vertical to and fro movement of the guide between the hook means, as the guide approaches each hook means in turn the guide partially rotating said hook means so that the elements are wound over it. One hook means is rotatably driven with respect to the other hook means to twist the elongate loops together to form a skein in which the twisted reinforced elements are held under tension between the two hook means. The skein is then cured.

  • Patent number: 4097318
    Abstract: A sealing apparatus for joining container parts of a plastic-lightweight metal foil laminate by heat and pressure applied to the laminates when the respective plastic layers are pressed into contact uses a toggle linkage and a yieldable buffer, with a hydraulic actuator to drive the toggle linkage to close a pair of sealing heads together. The toggle linkage permits build-up of pressure to a value predetermined by the construction of the buffer, after which the buffer yields to hold the sealing pressure. The duration of the build-up to sealing pressure comprises no more than 20% of the time interval between initiation of pressure build-up and the start of pressure drop-off at the end of the sealing process.

  • Patent number: 4095638
    Abstract: Self-curing elastomeric compounds in liquid suspension are sprayed onto a warmed rotating former having preferably a form developed from the radial dimensions of the inner tube to be made. The tube is cured and complete on the form by transposing one end of the sleeve to the opposite axial end of the former where the one end is seamed to the other end of the sleeve. Both the process and the tube produced by the process have advantages in manufacturing cost, in material saving, and at least equal quality performance relative to conventional inner tubes and methods of making them.

  • Patent number: 4095312
    Abstract: Method and apparatus for making a nonwoven fabric wherein a first group of filaments are projected in a longitudinal direction into the nip of a pair of nipped and moving collecting surfaces in such a manner that the filaments fold into and are captured and held by the nip with spans of the filaments lying in the plane of the nip and at the same time projecting a second group of filaments in a longitudinal direction toward one of the collecting surfaces at a location spaced from the nip. The second group of filaments impinges on an impact plate positioned above the collecting surface and is pulled off the impact plate by the moving collecting surface, this causing the filaments in the second group to extend primarily in the machine direction. The moving collecting surfaces carry the groups of filaments into contact with each other to form a nonwoven fabric which is subsequently bonded in a conventional manner to form a finished fabric.
