  • Patent number: 5323170
    Abstract: A radome constructed using a rigid or semi-rigid foam core and sandwich construction is described. The foam core radome virtually eliminates water absorption problems associated with present technology radomes. The radome also provides greater impact strength and consistent, high radar transparency without sacrificing weight and structural stability, thereby providing a much longer service life in moisture/impact critical environments. Preferably, the radome includes a vinyl rigid closed-cell foam core consisting of a polymeric alloy of a cross-linked aromatic polyamide urea and a linear vinyl polymer.

  • Patent number: 4321890
    Abstract: A surgical restrainer for an animal has a striplike structure including a central flat bottomed band with inverted V-shaped legs at opposite ends defining loops to receive forearms of an anesthetized animal resting in supine position on said band and cradled between said legs, so that the animal cannot roll over during surgery and post-operatively.

  • Patent number: 4200142
    Abstract: A no-fume riser neck for use in molding the connecting neck between the riser cavity and general mold cavity in the production of metal castings. The neck is generally cup-shaped and preformed of sheet metal with a closed and substantially sealed upper end and an open flared and grooved lower end which is positioned open-end down on the face of a foundry pattern so that the sealed upper end is gas tight and separates the open riser cavity from the mold cavity and prevents extraneous material from entering and contaminating the mold cavity, and also prevents the unrestricted escape of objectionable gases and fumes from the mold cavity to the environment during the pouring cycle.

  • Patent number: 4106633
    Abstract: This invention relates to punch presses having a transfer die and a work transfer mechanism for advancing individual workpieces progressively through successive tooling stations of such die at high speed comprising dual intermittent-feed transfer bars slidingly mounted for rotary movement and lifting of said workpieces off the tooling stations of said die, and associated clampbars which retain each workpiece on the transfer bars by free retention of the edges of the workpiece during transfer movement, and which transfer bars deposit said workpieces at the next successive tooling station by rotary movement to release the lifting support of each workpiece from below the same and from the free-retention clamping thereof from above in readiness for the next tooling operation.
