Patent number: 5458072Abstract: 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.Type: GrantFiled: April 6, 1994Date of Patent: October 17, 1995Inventors: David W. Hughes, L. Andrew Withers

Patent number: 5259501Abstract: The system (10) for collecting and disposing of personal-use hypodermic syringes (29) comprises a cylindrical container (11) and a telescopic cover 12. The container (11) includes a side wall (15) defining a collection chamber (19) for collecting used hypodermic syringes (29). The telescopic cover (12) includes an inner top wall (25) and an outer top wall (26) having an opening (28) therein, which is of sufficient internal breadth sized and shaped specifically for receiving hypodermic syringes (29). The used syringes (29) will be pushed through a scored portion (30) of the inner top wall (25), and then a barrel (31) portion of the syringe fits through the opening (28) formed by the outer top wall (26). The container (11) is sized and shaped so that once deposited in the collection chamber (19), the syringes (29) cannot turn end-for-end.Type: GrantFiled: September 10, 1991Date of Patent: November 9, 1993Assignee: McDonald, Withers & Hughes, Inc.Inventors: L. Andrew Withers, David W. Hughes

Patent number: 5245117Abstract: The container (11) includes a side wall (15) defining a syringe storage chamber (19) where a coiled strip pack (31) of syringes (29) is placed. A central core (35) is place concentrically within the container and forms a collection chamber (20) for used syringes. The side wall (15) includes an outlet opening (30) so that the strip pack (31) can be paid out through the opening (30) and the syringes can be dispensed. The used syringes (29) will be pushed, needle-first through the central opening (26) and into the collection chamber (20), whereby when all the syringes in the strip pack are used and deposited into the collection chamber, the entire container can be disposed of, as by burning.Type: GrantFiled: July 27, 1992Date of Patent: September 14, 1993Inventors: L. Andrew Withers, David W. Hughes

Patent number: 4432526Abstract: 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.Type: GrantFiled: January 4, 1982Date of Patent: February 21, 1984Assignee: L. Andrew Withers, Jr.Inventors: L. Andrew Withers, Jr., William D. Withers, Carlo Fineo

Patent number: 4385453Abstract: 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.Type: GrantFiled: April 28, 1981Date of Patent: May 31, 1983Assignees: Leland A. Withers, Sr., L. Andrew Withers, Jr.Inventors: L. Andrew Withers, Jr., Leland A. Withers, Sr., Jean D. Withers, Carlo Fineo

Patent number: 4385455Abstract: 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.Type: GrantFiled: November 3, 1981Date of Patent: May 31, 1983Assignees: Leland A. Withers, Sr., L. Andrew Withers, Jr.Inventors: L. Andrew Withers, Jr., Leland A. Withers, Sr., Jean D. Withers, Carlo Fineo

Patent number: 4385454Abstract: 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.Type: GrantFiled: October 2, 1981Date of Patent: May 31, 1983Assignees: Leland A. Withers, Sr., L. Andrew Withers, Jr.Inventors: Jean D. Withers, Carlo Fineo, L. Andrew Withers, Jr., Leland A. Withers, Sr.
