  • Publication number: 20110297205
    Abstract: A combination roofing panel and solar module includes a flexible membrane sheet, such as a single-ply membrane sheet, and a plurality of elongated solar or photovoltaic modules arranged side-by-side, end-to-end, or adjacent each other. The modules are adhered to the flexible membrane, and the edges of the modules having electrical connectors or electrodes are arranged to face each other or be aligned with each other. The electrical connectors are connected by a solder connection to module electrodes through apertures in a bottom surface of the flexible membrane and are connected in series. The series electrical connectors are connected directly to direct current (DC) electric devices, to a combiner box, to another panel or to an inverter which provides coverts direct current (DC) to alternating current electricity for use in residential, commercial or industrial building structures.

  • Patent number: 5174438
    Abstract: A conveyor belt that is constructed from a plurality of adjacent slabs. Each slab has a plurality of lugs on one side and a plurality of hooks on the other side of the slab. The lugs and hooks extend from a center plate section which provides the support surface for the products that are to be moved by the conveyor. Each slab has a pintle that is inserted into the lugs while the slab is still in a heated super plastic state. Subsequent cooling of the slab causes the lugs to shrink around the pintle such that the pintle is securely fastened to the slab. The pintle extends between the lugs so that the hooks of an adjacent slab can be inserted into the pintle to attach the adjoining slab.

  • Patent number: 4860509
    Abstract: A combination form of flexible roofing material including a reinforced single-ply membrane base for being adhered to the roof substrate. On the base is laminated a structurally flexible layer of solar cells encapsulated and sealed in a flexible intermediate layer of solar radiation transparent plastic protected by a cover layer of weather-proof solar transparent plastic. The roofing is constructed for being manufactured in elongate sheets, rolled up for transport to the site and installed by conventional methods including sealing to adjacent sheets of similar single-ply membrane material which may or may not incorporate solar cells. This is continued until the roof covering is complete. Examples are given for reinforced plastic sheet, modified bituminous sheet, and elastomeric sheet roofing materials as well as for a wide variety of solar cells materials together with methods for fabricating these materials into the roofing system disclosed.

  • Patent number: 4440588
    Abstract: An improved hot air welder which includes a blower communicating with a heater assembly mounted on a chassis wherein the chassis has coupled thereto a pressure wheel and tracking wheel, includes means for adjusting the angle of orientation of the pressure wheel and tracking wheel with respect to the chassis in order to obtain a proper pressure bias through the pressure wheel on the seam over which the pressure wheel rides, and for providing a proper orientation of the tracking wheel according to the slope of the roof upon which the welder is driven. The welder can accommodate inside and outside seams with equal facility. The air dam has an improved roller track to more evenly apply pressure against the underlying roofing material. A guide member slidably engages and accommodates roofing material from both the left and right sides to assist in guiding the hot air welder along the seam to be welded. A constant speed blower controlled by a gate valve controls the amount of air to the heater assembly.
