  • Process and apparatus for the molding of shaped articles from a composite metallic refractory material
    Patent number: 4175609
    Abstract: Disclosed are a method and apparatus for molding articles in which a highly planar solidification front is desired. A charge of liquefied alloy to be molded into the desired article is placed in a mold and submerged in a heat-exchange bath of liquid metal forming a cylindrical column which is heated in an upper portion and cooled in a lower portion to define an intermediate level at which the bath temperature corresponds to the melting point of the alloy. Upon a progressive lowering of the mold within the bath, a solidification front formed in the alloy at that intermediate level advances from the bottom to the top of the charge.

  • Method and apparatus for forming a metal strip
    Patent number: 4173879
    Abstract: A method and apparatus for forming a metal strip into a shape having a transverse concave, convex bow, for example, for forming slats for venetian blinds. The strip material is fed into the nip of a pair of forming rolls having complementary concave and convex peripheral surfaces, to provide the bow. In order to ensure that the resulting bowed strip is formed without any twist, the strip is fed along a substantially straight path upstream of the forming rolls, and the direction of this straight path is adjustable in a plane passing through the nip and parallel to the axes of the forming rolls.

  • Soil cultivating implements
    Patent number: 4173260
    Abstract: An agricultural implement has a main frame and laterally positioned carrier frames pivoted to the sides of the main frame. The main frame extends forward to a coupling point for connection to a prime mover. The rear of the main frame mounts a hydraulic piston assembly that is interconnected to each carrier frame to elevate same into an upward tilted transport position. Each frame and carrier frame supports a frame portion having a respective group of rotatable soil working members positioned in a row to work a broad path during working operation. Connecting members on the carrier frames are connected to the central frame portion to raise same when the carrier frames are in their tilted transport positions. Latches supported on the main frame secure beams of the carrier frames in their tilted positions until release.

  • Method of forming non-woven net structures
    Patent number: 4172748
    Abstract: A non-woven net structure is formed from initially-independent threads inding a thermoplastic synthetic plastic material. The weft threads are located in axially-extending grooves in the surface of a rotatable cylinder. The warp threads are located in circumferentially extending grooves which may be in the surface of the same or a different cylinder. The threads are heated and are moved by cylinder rotation into intersecting relationship in a roller nip where pressure is applied to bond the threads at their intersections while the threads are in the grooves. The net structure may be bonded to or integrated with a thermoplastic synthetic plastic material in sheet form in the same operation. A subsidiary feature is a novel form of weft thread distributing apparatus.
