摘要:
An elongated perimeter light is disclosed, which comprises a linear array of light sources (LEDs) that are electrically illuminated. The array of light sources is disposed within an elongated transparent tube, with the tube transmitting and dispersing the light from the array giving the appearance that said array of light sources is a continuous light source. The array of light sources is capable of being cut at intervals down its length to shorten it. The light sources that remain in the array continue to emit light and the tube can be cut to match the length of said array. The present invention also discloses systems for lighting structural features, with one system according to the present invention comprising a plurality of elongated perimeter lights. The perimeter lights are electrically coupled in a daisy chain with the electrical power at each of the perimeter lights being transmitted to the successive light. A mechanism is included for anchoring the plurality of perimeter lights to a structure to illuminate it. Each of the perimeter lights can be cut at intervals down its length while not interfering with its ability to transmit its electrical power to successive lights.

An apparatus for providing zonal isolation in a wellbore includes a plurality of interlocking sealing elements having anchor elements at the opposing ends. Each anchor element sealingly engages a wellbore tubular whereas the interlocking sealing elements do not engage any portion of wellbore therebetween. In one exemplary application utilizes a wellhead and lubricator positioned over a wellbore under pressure and a conveyance device for conveying equipment into the wellhead. The first anchor, the second anchor and the plurality of interlocking sealing elements are separately conveyed into the wellbore with the conveyance device and sequentially assembled in the wellbore to provide zonal isolation.

This invention is a process of preparing a glazing structure that is a glass laminate having enhanced resistance to being pulled from a frame upon being subjected to high positive and/or negative pressure loads. This invention is particularly suitable for architectural structures having windows that can be subjected to the extreme conditions prevalent in a hurricane, bomb-blast event or placed under stress from repeated forceful blows to the laminate.
摘要:
The present invention is a direct-point attachment laminate system comprising: (1) a thermoplastic interlayer; (2) at least one sheet of a rigid structural load-bearing layer (structural layer); (3) at least one receptor means; and (4) at least one attachment means, wherein the thermoplastic interlayer is bonded on at least one surface to at least one sheet of the structural layer, and wherein at least one receptor means is also adhesively bonded to the thermoplastic interlayer and thereby adhesively bonded to the structural layer, wherein the receptor means is positioned to mechanically accept the attachment means, with the further proviso that the attachment means and/or the receptor means are made from materials having a coefficient of expansion that is from about 90% to about 110% of the coefficient of expansion of the structural layer.
