Patent number: 4783185Abstract: A pen-like dispenser for applying rust converting liquid including a cap having an outer abrading surface adapted to scrape loose paint and rust from a surface to which the liquid is to be applied; and a liquid dispensing part including an elongate fluid reservoir having resiliently flexible walls, and a dispensing tip assembly. The tip assembly includes a valve member normally closing the tip assembly and having a tip projecting through an outlet passageway through the housing under the influence of a spring. The valve member may be moved to an open position by pressing its tip against a rusted substrate to afford outflow of the liquid, which flow can be controlled and aided by pressing inwardly on the flexible walls of the reservoir.Type: GrantFiled: July 7, 1986Date of Patent: November 8, 1988Assignee: Minnesota Mining and Manufacturing CompanyInventors: David W.

Patent number: 4497760Abstract: A method of repairing damage to the sheath of a communications cable in which a heat shrinkable material is wrapped around the communications cable to bridge across the damaged area of the sheath. A flexible strip heater having a base with a heating element in a portion of its width and a parallel insulating layer overlying only a portion of the base is wrapped in a spiral around the heat shrinkable material with the portion having the insulating layer wrapped on the portion of the previous turn not having the insulating layer. The insulating layer substantially abuts itself in adjacent turns of the heater to position the portions of the base containing the heating element adjacent each other along the heat shrinkable material. The heating element is activated to cause the heat shrinkable tape to shrink tightly onto the communications cable to cover the damaged portion of the sheath and, the flexible strip heater is then removed.Type: GrantFiled: March 2, 1983Date of Patent: February 5, 1985Assignee: Minnesota Mining and Manufacturing CompanyInventor: Mark D. Sorlien

Patent number: 4441017Abstract: A strip heater for wrapping around and applying heat to elongate generally cylindrical objects has a thin, flexible, elongate fiber reinforced base with a uniform width along the majority of its length, resistance wire insulated within the base across a uniform portion of the width of the base and a flexible insulating layer having a width equal to that of the portion of the base containing the resistance wire and overlying only a portion of one surface of the base. The heater is designed to be wrapped around a cylindrical object, such as a communications cable, with the thicker insulating portions overlying the portions not having the insulating layer and abutting itself in adjacent turns around the object to position the portions of the base containing the resistance wire adjacent each other in the spiral adjacent the object.Type: GrantFiled: March 2, 1983Date of Patent: April 3, 1984Assignee: Minnesota Mining and Manufacturing CompanyInventor: Mark D.
