Title: Antireflective graded index silica coating, method for making, and coating solution for applying
Inventor: YOLDAS BULENT E
IPC: C03C17/27
Filed: 1984-05-31
Granted: 1987-03-03
Abstract: 51,141 Antireflective silica coating for vitreous material is substantially non-reflecting over a wide band of radiations. This is achieved by providing the coating with a graded degree of porosity which grades the index of refraction between that of air and the vitreous material of the substrate. To prepare the coating, there is first prepared a silicon-alkoxide-based coating solution of particular polymer structure produced by a controlled proportion of water to alkoxide and a controlled concentration of alkoxide to solution, along with a small amount of catalyst. The primary solvent is alcohol and the solution is polymerized and hyrolized under controlled conditions prior to use. The prepared solution is applied as a film to the vitreous substrate and rapidly dried. It is thereafter heated under controlled conditions to volatilize the hydroxyl radicals and organics therefrom and then to produce a suitable pore morphology in the residual porous silica layer. The silica layer is then etched in order to enlarge the pores in a graded fashion, with the largest of the pores remaining being sufficiently small that radiations to be passed through the substrate are not significantly scattered. For use with quartz substrates, extremely durable coatings which display only 0.1% reflectivity have been prepared.

Abstract: Abstract A composite band for use in a footwear-forming machine.          The composite band includes an elongated pad formed to have a bight portion and a pair of legs extending outwardly from the bight portion.          A flexible elongated metal is secured at the outer surface of the elongated pad. The composite band is subjected to flexing forces whereby, in the footwear forming process, it is repeatedly bent to conform to the shape of the footwear and then relaxed to an unflexed condition. The metal skip contains three (or more) spaced loops, one at each leg and one at the bight portion, to prevent undue stress during flexure. The loops serve also to permit inwardly-directed forces to be applied to the composite band.

Abstract: ABSTRACT         A portable bandsaw mill, readily made sufficiently light in weight to be carried by two people, having a saw unit supported on rollers, so that the saw unit can be readily guided and the cut controlled and adjusted manually.  A ground-supported support frame or unit provides guide tracks spaced apart on opposite sides of a log or other workpiece, on which the saw unit can be rollingly advanced.  The ends of the guide tracks are supported in end frames by means enabling the levels of the guide tracks to be conveniently adjusted for successively lower passes of the saw unit through the log.          Guide beam ends are capable of independent adjustment to accommodate differences in level between the four corners of the support unit.  A manually advanced rolling saw head of the saw unit includes two bandsaw pulleys, each having a bandsaw blade entrained thereon, one being an idler pulley and the other a drive pulley.  The drive pulley, rotatably driven, can be powered by a hydraulic motor, with the actual pressure fluid source separate from the mill.  The motor can be readily separable from the saw unit for use in powering other apparatus.  The mill can be readily employed for rip sawing logs into boards at any convenient location for example the felling site.

Abstract: INTERFACE DESIGN OF TWO CLAMPED-TOGETHER PARTS           Abstract of the Disclosure Two control valve housings each have a longitudinal bore receiving a valve spool.  The housings are clamped together by two pairs of bolts located one on each side of the bores. Formed on one of the parts at the interface of the two parts and at opposite sides of each bolt is a pair of roughened surface areas which are prepared by milling or stamping.  By means of such a surface preparing method projections are created which are deformed and serve as spacers between the two parts when they are clamped together.  The two parts then touch themselves only in the roughened surface areas.  Thus, when the two parts are clamped together any distortion in the area of the longitudinal bore is avoided and the valve spool can move in the longitudinal bore, noneffected by the force acting on the two parts.

Abstract: ABSTRACT A solid state imager wherein a pixel non-uniformity correction system compensates for photosite non-uniformities by providing a linear correction method and utilizing three modes: mode #l - dark current detection, mode #2 - uniform illumination, and mode #3 -data detection mode. In the first calibration cycle, the outputs of all the photocells on an imager 10, representing "dark current" are stored in an "offset" memory 14. In the second calibration cycle, a uniform illumination from a constant light level is applied to the imager 10. This uniform illumination signal is passed to an arithmetic unit 18 where the dark current signal is subtracted from it and the difference is then stored in gain memory 28. The gain memory passes this signal back to the arithmetic unit 18, so that in the third mode, the data detection mode, the arithmetic unit 18 can electronically correct the data signals that were non-uniformly affected by the internal characteristics of the imager.
