  • Patent number: 4345927
    Abstract: An apparatus and process is provided for more random distribution of a bundle of strands into a continuous strand mat. The apparatus has a feeder for reciprocating, traversing deposition of strands onto a conveyor, where the feeder is positioned above the conveyor that moves in a direction around 90.degree. from the direction of deposition of the strands across the conveyor. The feeder has a pulling means to pull the strands into the feeder and to deliver the strand to an accelerating means on the feeder which then increases the speed of the strands to contact a convex surface deflector attached to the feeder to dispose of the strands onto the moving conveyor. If the feeder traverses the conveyor on an axis above the conveyor the accelerating means and convex surface deflector are affixed to the feeder and move with the feeder. If the feeder is stationary but has a reciprocating traversing part, then the accelerating means and deflector move with the reciprocating traversing part.

  • Patent number: 4342581
    Abstract: A process is described for preparing continuous strand mat which provides for more uniform density of the mat across the width of the surface on which it was prepared by using gaseous fluid directed mat edges to fold loose strands at the edges under the mat and to align the edges of the mat in a substantially straight line. The gaseous fluid, preferably air, is directed at the conveyor surface on which the mat is formed against the flow of the mat on the conveyor and in a downward direction so that portions of the mat at the sides are lifted by the air as the stray strands are folded under to form the straight edge. A further embodiment includes the formation of an edge on a continuous strand mat having an already formed substantially straight edge, during a needle operation to minimize edge waste during needling.

  • Patent number: 4234351
    Abstract: The process includes the steps of (1) forming a pattern of indentations and adjacent boundary ridges in a base layer of glass which is heated to a temperature where it is formable but not flowing, (2) depositing electrically conducting first connecting elements on the upper surface of the base glass layer, with each first connecting element extending from an indentation to a point on an adjacent ridge, (3) positioning a solar cell into each indentation in the base glass layer in such a manner that the lower surface of the solar cell comes in electrical contact with one end of a first connecting element, (4) depositing electrically conducting second connecting elements which extend between the end of the first connecting elements on a ridge to the top surface of a solar cell in an adjacent indentation, and (5) forming a top glass layer which is in intimate contact with the product of steps 1-4.

  • Patent number: 4157929
    Abstract: The plate-like structure is formed of glass filaments and a solid ceramic skin which envelopes the glass filaments to form a skeleton-like supporting structure. The glass filaments are also fused to each other at intersecting points to impart stability to the structure.The method of making the structure includes the steps of forming a coating of a ceramic substance which is capable of being fired on a flat structure of glass filaments. Subsequently, the coated structure is fired at a temperature in a range from 600.degree. C. to 1500.degree. C. to form a solid skin of the ceramic substance while causing the glass filaments to fuse together at the intersecting points of contact.Packings for material and heat exchange processes can be made from the plate-like structures.

  • Patent number: 4083710
    Abstract: A first die having a relief pattern is employed to provide predetermined shape and relative positioning for a first plurality of metal strips. A second die is similarly employed for a second plurality of metal strips Without removing the metal strips from the dies, the strips, still in predetermined shape and position, are bonded to opposing surfaces of an insulating substrate. The bonding process includes bringing the dies, and hence, the metal strips, into contact with the opposing surfaces of the insulating substrate. The bonding process may include the application of heat, pressure, and an electrical field across the bonding interfaces, e.g., anodic bonding.

  • Patent number: 4074994
    Abstract: The process comprises continuously forming a glass strip on surface of molten metal and concurrently treating the glass surface in plastic state with a reactant. The reactant comprises a substance which is capable of forming a surface layer having a viscosity which is substantially greater than the viscosity of the basic glass mass. The distinctive feature of the process consists in that the glass strip treated with the reactant is subjected to deformation so as to form rips which define, in combination, an ornamental pattern of glass. The apparatus according to the invention is characterized in that each conduit has an independent system for reactant supply to the glass surface, and all conduits are arranged in a hollow casing filled with a cooling medium, and driven endless tracks are provided downstream the casing in the direction of glass flow which are in contact with the glass strip.
