Abstract:
Devices for repelling or discouraging rodents from accessing wires or cables on utility poles are presented, along with the method of manufacturing the same. According to preferred embodiments of the invention, a rodent-repellent additive is blended with a thermoplastic elastomer or rubber and then extruded into a tubular member that may be placed around existing cables and wires maintained by a utility pole. A squirrel or other rodent typically desiring to gnaw on the insulation or the wires themselves will be discouraged from such activity by the odor attendant to the material from which the tubular member or sleeve guard is manufactured. If not so discouraged, the taste of the material will conclusively discourage such activity. That same material may be extruded in the form of a flat, elongated extrudate cut to length to form bands that may be placed about the utility pole beneath areas requiring protection from squirrels or the like.
Abstract:
Liner for dispensing container, especially a self-pressurized container of the non-aerosol type. The liner is preferably plastic but not elastomeric, and is radially expandable and longitudinally essentially inextensible. The liner has an open end, a closed end, a sidewall extending from the open end to the closed end and a tip at the closed end. The liner has 12 to 20 side by side longitudinally extending pleats which form alternating peaks and valleys, with an acute apex angle not greater than 70.degree. at each peak. The pleats extend through the mid-section and the lower portion of the liner. The lower portion is tapered. The liner is about 0.1 to 0.3 inches thick at the tip. The average sidewall thickness is about 0.010 to about 0.02 inch over substantially the entire length of the sidewall. The liner as formed is pleated and has memory so that it returns to the pleated state when unstressed.
Abstract:
A cable marker used to identify associated cables. The cable marker is made of a weatherable polymeric material which remains flexible in variable temperature conditions. The cable marker is substantially elliptically shaped allowing the marker to adjust to fit cables of varying diameter. The cable marker has a plurality of sizing lugs and a diametrically opposed locking lug to facilitate sizing and locking of the cable marker to the cable. Engraving and foil printing permanently identify cables in addition to color coding.
Abstract:
Self-pressurized container which comprises a liner/sleeve assembly containing a thin, flexible radially expandable convoluted plastic liner, about 0.010 to about 0.020 inch think, inside an essentially cylindrical elastomeric sleeve. The liner is generally cylindrical, open at one end and closed at the other end, and comprises an outwardly turned flange and an upper sidewall adjacent to the open end and a convoluted portion comprising longitudinally extending convolutions which extend from the upper sidewall towards the closed end. The liner is formed in the convoluted state, and has memory so that it returns to the convoluted state when unstressed. The outside diameter of the liner, measured between diametrically opposite peaks of the convolutions when the liner is unstressed, exceeds the inside diameter of the elastomeric sleeve when unstressed. Both liner and sleeve expand radially outwardly when the liner is filled under pressure with product to be dispensed. The liner/sleeve assembly is capable of holding a substantial quantity of fluid product and of causing substantially all of said product to be dispensed. The top assembly of the container is similar to that of a conventional aerosol container, comprising a valve assembly with a metallic cup whose rim is crimped around a ring surrounding a central opening of a metallic dome, but with a part of the upper sidewall of the liner clamped between the cup and the dome ring as a gasket to form a fluid tight closure for the liner.
