  • Patent number: 5385105
    Abstract: The system (10) for collecting and disposing of contaminated waste products such as medical sharps and other medical wastes includes a housing (11) and its telescopic cover (9) which are fabricated of biodegradable and combustible material such as natural cellulose and non-natural cellulose. An absorbent biodegradable and combustible absorption package (30) or insert (35) can be placed in the bottom of the holding chamber (12) for absorbing any liquids emitted from the sharps and other wastes, and for enhancing the combustion of the medical sharps and other wastes when the housing is placed in a furnace. When the housing is burned it evolves no more than trace levels of sulfur or chlorine and yields substantially only biodegradable ash.

  • Patent number: 4432526
    Abstract: A pair of support blocks of similar construction are connected together by a flexible strap extending therebetween. Each support block includes a platform for engaging a floor surface and a support plate positioned on the platform, and an end portion of the strap extends between the support plate and the platform of each support block. The support plate of each of the support blocks is hingedly connected to its platform and includes an upwardly facing support surface sloped downwardly toward the opposite support block whereby a cylindrical roll or the like can be placed on and supported by the support blocks, with the support blocks forming wedges on opposite sides of the cylindrical roll.

  • Patent number: 4385453
    Abstract: A lightweight plyable heat and noise end panel insulator panel is mounted to the exterior surface of the axial end wall of a temperature controlled cylinder. The insulator panel comprises multiple layers of heat and noise insulation material and relatively non-stretchable material stitched and grommeted together whereby a pattern of pockets are formed to hold the fragile heat insulation in place. The panel defines a central opening and a slot extending from the central opening through the outer peripheral edge portion so that the panel can be positioned about the axle of the cylinder.

  • Patent number: 4385455
    Abstract: A lightweight pliable heat and noise insulator blanket is mounted to the exterior surface of the axial end wall of a temperature controlled cylinder. The insulator blanket comprises multiple layers of heat and noise insulation material, and the blanket defines a central opening and a slot extending from the central opening through the outer peripheral edge portion so that the blanket can be positioned about the axle of the rotary cylinder. The insulator blanket includes an annular protrusion just inwardly of its outer periphery for placement against the exterior surface of the axial end wall of the rotary cylinder to form a seal between the insulator blanket and the rotary cylinder. The outer peripheral portion of the insulator blanket extends about the connector screws of the rotary cylinder while the annular seal of the insulator blanket is urged by centrifugal force toward a sealed relationship between the insulator blanket and the axial end wall of the rotary cylinder.

  • Patent number: 4385454
    Abstract: A lightweight pliable heat and noise insulator blanket is mounted to the exterior surface of the axial end wall of a temperature controlled cylinder with band clamps that grasp adjacent ones of the connector screws that hold the end panel to the cylinder. The insulator blanket comprises multiple layers of heat and noise insulation material, and the blanket defines a central opening and a slot extending from the central opening through the outer peripheral edge portion so that the blanket can be positioned about the axle of the rotary cylinder. The band clamps each include a band formed in a closed shape for positioning about adjacent ones of the connector screws of the rotary cylinder, and a mounting block positioned between the connector screws.
