Abstract: A wind-resistant shingle and a method of making it is provided in which the rear surface of the shingle is provided with an attached reinforcement layer, which resists upwardly wind-applied bending torque when the shingle is installed on a roof, such that the failure of the shingle when it is bent beyond its elastic limit, is resisted until the shingle has absorbed a high percentage of applied torque.

Abstract: A composition roofing shingle is described which has release material affixed thereto for the purpose of identifying the compositional shingle with process parameters for the time frame of manufacture. The identification is achieved by marking the release material with planographic idicia by means such as printing, stamping and ink-jet spray application.

Abstract: A shingle and a method of applying the same to a roof is disclosed, in which the shingles are wind-resistant, opposing being torn from a roof by wind or the like. The shingles each include a pair of vertically spaced-apart lines extending horizontally across the lower ends of butt portions of the shingles, with at least a lower-most line being a line of sealant, and defining between the vertically spaced-apart lines a fastener zone, which fastener zone may have fastening spots therein that, in turn, may define a fastening line. When shingles in accordance with this invention are applied to a roof, the line of adhesive connection between tab portions of shingles in an overlying course are secured to lower ends of butt portions of the shingles of a subjacent course, sufficiently low below the tab portions of shingles, as to preclude any significant engagement by wind or the like that may tend to lift the tab portion off the sealant line.

Abstract: A clean-out tool system for use with a oil well production tubing extending downward through a casing terminating in a production zone in the well bore, which zone is isolated by a packer and includes flow restricting debris to be cleaned out. A generally vertical, elongated, cylindrical tool body, having a relatively small diameter and a bore therein, is located down through the inner production tubing into the zone located at the end of a tubing string extending downward through the production tubing for communicating fluid pressure to the bore in the body. Four, peripherally spaced, elongated slots extend radially inward into the body with their longitudinal axes aligned with the longitudinal axis of the body and communicate with the bore is the body. An elongated blade is pivotally attached in each slot to the body, movable from a first configuration wherein the blade is positioned vertically within the slot, and a second, expanded configuration positioned radially outward in the zone.

Abstract: A down-hole oil field cable abrader having an elongated abrading head pivotally connected at one of its ends to a body attachable to a tubing string. An abrading portion extends axially along the abrading head from its pivotal connection and includes a plurality of abrading elements, similar to the cutting elements on a drill bit, spiralling axially about the abrading head ending in a taper to an area distal to its pivotal connection.

Abstract: A disc brake assembly utilizing pelletized brake lining material in a torque absorbing chamber is disclosed. The chamber is positioned around and over the disc and radially inward on opposite sides of the disc. The chamber has an internal cavity for the storage of brake lining pellets therein and a mechanism for moving the brake lining pellets against the disc to transfer torque from the disc to the cavity. A mechanism replenishing the brake lining pellets in the cavity of the chamber when at least one of the brake lining pellets is expended is also provided. In the preferred embodiment, a magazine pellet feeder mechanism, coacting with a pawl, feeds the brake lining pellets from a reservoir to the cavity in the chamber. In an alternate embodiment, a screw type pellet feeder mechanism coacts with a pawl to feed the brake lining pellets from a reservoir to the cavity in the chamber.
