  • Tray and beverage container holder
    Patent number: 5713546
    Abstract: A foldable holder for beverage containers and other items has a generally horizontal tray provided with a hole for accommodating a beverage container. A U-shaped member pivotally mounted to the tray traverses the bottom of the hole to provide a support for the beverage container and retain the container within the hole of the tray. The tray is supported above the ground with a stake pivotally connected to one end of the tray. The stake can be pivoted into a side-by-side relationship relative to the tray to facilitate the carrying and storage of the holder. The U-shaped member is also pivoted in a generally folded position relative to the tray, so the entire tray is located in a generally common plane.

  • Muzzleloader firearm
    Patent number: 5678341
    Abstract: A compact muzzleloader firearm has a barrel and a ramrod mounted below the barrel.

  • Easily sterilizable glove system
    Patent number: 5662581
    Abstract: An easily sterilizable glove system for use for performing work within a glove box or similar sealed enclosure within which operations are carried out under sterile conditions. The shoulder end of an elongated arm-length impermeable leak-proof flexible sleeve having a flexible impermeable leak-proof glove at the wrist end is held clamped between a smooth surfaced annular lip in a port in the wall of the enclosure and a compressed O-ring. The minimal area of sealing contact between two smooth surfaces is easily sterilized by the vaporous sterilants commonly used. Preferably the glove is separable and replaceable and similarly held between a smooth surfaced annular lip in a port at the wrist end of the sleeve and the compressed bead at the cuff of the glove, defining another easily sterilizable minimal area of sealing contact.
