Artificial Stone Block. (open access)

Artificial Stone Block.

Patent for a new and improved artificial-stone block. This design "consists in the particular formation of the protuberances by which interlocking joints or seams of the building-blocks are attained, the object of which is to so form the prolific protuberances of said blocks as to permit joining them in close proximity on all the sides or faces of the seam, to reduce the binding material for the same and increase the strength of the same" (lines 14-22).

Interline Transfer CCD Camera (open access)

Interline Transfer CCD Camera

An interline CCD sensing device for use in a camera system, includes an imaging area sensitive to impinging light, for generating charges corresponding to the intensity of the impinging light. Sixteen independent registers R1 - R16 sequentially receive the interline data from the imaging area, corresponding to the generated charges. Sixteen output amplifiers S1 - S16 and sixteen ports P1 - P16 for sequentially transferring the interline data, one pixel at a time, in order to supply a desired image transfer speed. The imaging area is segmented into sixteen independent imaging segments A1 - A16, each of which corresponds to one register, on output amplifier, and one output port. Each one of the imaging segments A1 - A16 includes an array of rows and columns of pixels. Each pixel includes a photogate area, an interline CCD channel area, and an anti-blooming area. The anti-blooming area is, in turn, divided into an anti-blooming barrier and an anti-blooming drain.

Segregated tandem filter for enhanced conversion efficiency in a thermophotovoltaic energy conversion system (open access)

Segregated tandem filter for enhanced conversion efficiency in a thermophotovoltaic energy conversion system

A filter system to transmit short wavelength radiation and reflect long wavelength radiation for a thermophotovoltaic energy conversion cell comprises an optically transparent substrate segregation layer with at least one coherent wavelength in optical thickness; a dielectric interference filter deposited on one side of the substrate segregation layer, the interference filter being disposed toward the source of radiation, the interference filter including a plurality of alternating layers of high and low optical index materials adapted to change from transmitting to reflecting at a nominal wavelength {lambda}{sub IF} approximately equal to the bandgap wavelength {lambda}{sub g} of the thermophotovoltaic cell, the interference filter being adapted to transmit incident radiation from about 0.5{lambda}{sub IF} to {lambda}{sub IF} and reflect from {lambda}{sub IF} to about 2{lambda}{sub IF}; and a high mobility plasma filter deposited on the opposite side of the substrate segregation layer, the plasma filter being adapted to start to become reflecting at a wavelength of about 1.5{lambda}{sub IF}.
