摘要:
The present invention relates particularly to photovoltaic systems for use in photovoltaically generating electrical energy. One aspect of the invention is a photovoltaic roofing system including a plurality of photovoltaic elements contiguously disposed on a roof deck arranged in at least two horizontal rows, defining a photovoltaic area; a plurality of roofing elements disposed adjacent the contiguously-disposed photovoltaic elements, along their side edges; side flashing disposed along the side edges of the contiguously-disposed photovoltaic elements, the side flashing having a flange facing away from the photovoltaic area at least partially disposed between a roofing element and the roof deck, and a structure at least partially disposed on the surface of the photovoltaic element or at least partially disposed between a photovoltaic element and the roof deck.

A method of making a shingle and the shingle made in accordance with such method are provided, in which a shingle-forming layer of shingle material has a plurality of marks applied thereto prior to or after application of decorative granules to its tab region, and wherein the locations of the marks are sensed by a sensor, that then activates and controls the operation and placement of various shingle-completion steps as a function of the placement of the marks.

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. The blade is pivoted to its second configuration responsive to increasing pressure in the tubing string and is limited in its movement by the degree of an upper cam face onthe blade preventing any cutting engagement between the clean-out blades and the interior surfaces of the casing. The tubing string is moved longitudinally and rotated, rotating and moving the blade in its second configuration within the zone, loosening debris which is then removed by fluid circulation. The blades are provided in sets for different expansion sizes.

The present invention relates generally to photovoltaic systems. The present invention relates more particularly to photovoltaic roofing systems in which photovoltaic elements are disposed upon roofing elements such as shingles, tiles, shakes or slates. For example, in one embodiment, the present invention provides a photovoltaic roofing system for use on a roof deck, the photovoltaic system including a plurality of horizontally-arranged first photovoltaic roofing elements disposed on the roof deck, each having a top end and a bottom end; one or more first flashing elements disposed on the roof deck upwards from the first photovoltaic roofing elements, the first flashing element having a top end, and a bottom end overlapping the top end of one or more of the first photovoltaic roofing elements; and a plurality of horizontally-arranged second photovoltaic roofing elements disposed on the roof deck upwards from the one or more first flashing elements, each second photovoltaic roofing element having a top end, and a bottom end overlapping the top end of one or more of the first flashing elements, the second photovoltaic roofing elements not overlapping the bottom end of any of the first flashing elements.

A weather resistant shingle system is provided, wherein a starter strip course of shingles is applied to a roof, and with successive courses of field shingles applied thereover, with adjacent underlying and overlying shingles adhesively secured together to provide wind resistance to tabs of next overlying shingles from being upwardly lifted under wind conditions, and to prevent moisture, such as rain, from entering beneath tabs of shingles.

A packaging box is provided, for specialty shingles, wherein there are provided multiple compartments of an interior box, for accommodating shingles, with a sleeve disposed thereabout, and with a handle of the box projecting through an upper wall of the sleeve, with there being no bottom wall for the sleeve, to accommodate ready removal of the sleeve from the multiple-compartment box. A projecting handle of an underlying box can be accommodated in an opening of a next overlying box, when the packages are assembled in stacked relation one upon the other, such as in palletized form.

An asphalt shingle is provided, in which a base mat is impregnated with an asphalt material and has headlap and tab portions, with the tab portion being a plurality of tabs separated by slots, with adhesive applied to the top surface of the shingle in the headlap portion and above the upper ends of the slots, but wherein the headlap portion of the shingle has adhesive-free zones above the centers of the tabs.A roof covering is provided with the shingles being in overlying and underlying courses, with shingles in each course being laterally offset and with the adhesive-free zones being such that no adhesive on a shingle in an underlying course is visible through slots of shingles in a next-overlying course.The method of making the asphalt shingles includes applying a substrate to a layer of shingle-forming material, the substrate having indicators at predetermined spaced-apart distances, with the indicators being sensed as the shingle-forming layer is moved along a predetermined path, with adhesive zones being applied to the shingle such that the application of the adhesive zones is synchronized in response to sensing the locations of the indicators, and with the shingle-forming layer then being cut into individual shingles.
