Abstract: ABSTRACT OF THE DISCLOSURE A particular range of glass compositions in the soda-boro-silicate glass system has been found to be part-icularly suitable for ultra-low loss dielectric optical waveguides.   By preparing such glasses in a reducing atmosphere (0.20% CO in CO2) and about 1% As2O3 to the melt attenuation coefficients due to copper and iron can be mini-mized.   The water content of the glass can be reduced by bubbling dry CO in CO2 through the molten glass.  Glasses containing less than 30% Na2O by weight have the lowest losses. Using glasses of this type dielectric optical waveguides having an insertion loss of less than 14 dBKm-1 have been made.

Abstract: ABSTRACT     In the manufacture of insulating and lightweight construction materials, which can contain fillers, and which were produced by physical foaming; the addition of fillers has involved difficulties.  This arises because materials having relatively rough surfaces, as with most fillers, accelerate the collapse of liquid foams so greatly, that the addition of fillers was a problem in the case of physically foamed resins.  The process of this invention increases the stability of reaction resin foams and conden-sation resin foams, so that the foam can be mixed with curing agents and accelerators, as well as lightweight fillers, and if appropriate, heavier fillers. The process involves contacting a thin film of the liquid resin, in a pressure vessel, with a blowing agent, causing the liquid resin to flow, without absorbing bubbles of the agent, down an elongated surface.  The liquid resin film absorbs the agent so rapidly, that the flowing film can be immediately withdrawn from the vessel, and allowed to expand and cure into a foamed resin.

Abstract: An air-borne radar system for terrain-imaging employs a sidelooking synthetic-aperture radar that records reflected signals on photographic film.  Range data has a constant focal length whereas data in an azimuth direction has a focal length that varies as a function of range and therefore requires opt-ical correction.  A known processor system brings the various focal planes into coincidence using a complex lens structure that includes a computer generated spatial filter.  A novel method and apparatus is disclosed for interferometrically gen-erating a two-dimensional spatial filter is more simple and economical to produce.  Means are provides for diffracting a source beam of coherent light into a beam having a predeter-mined amplitude distribution.  The resulting beam is imaged through a lens system onto a light responsive recording medium together with direct illumination from a reference source of coherent light to obtain a predetermined intensity distribution.          The intensity of the exposing light is determined by both a magnification and a Fourier transformation of the diffracted beam.  After development, the recording medium has an amplitude transmittance necessary for the desired spatial filter and may be used directly in the known processor system.

Abstract: ABSTRACT OF THE DISCLOSURE    A multilayer printed circuit board structure and a method for generating artwork masters for the manufacture thereof.  The multilayer board comprises universal internal layers of prede-fined circuit patterns.  The internal layers include power and ground planes, and for boards having high component and circuit density, one or two signal crossover layers with short, equal-length runs oriented transversely to the runs of an adjacent out-ermost signal layer.  Electrical interconnections between layers of the circuit board are effected by interlayer conductors such as pins or plated-through holes at predefined locations.  The artwork masters for the outermost layers are generated utilizing two degrees of layout precision.  A universal layout master hav-ing interconnection pads and parallel circuit runs extending across the entire surface of the board is first prepared using a high degree of precision.  The universal layout master is then superposed with other layout masters including a component matrix and utilized to generate a composite artwork master having rela-tively short circuit runs of a second degree of precision inter-connecting the parallel runs and the pads.  A tool for a unique outermost layer is then reproduced from the composite artwork master utilizing an artwork master of another layer to control interlayer registration.

Abstract: TAPE CARTRIDGE HAVING A SHUTTER WITH         SELF-LOCKING FUNCTION       Abstract A tape containing cartridge has a front wall with a transducer-receiving opening and a side wall has a capstan-receiving opening.  A flexible sliding shutter is disposed in a shutter guide extending across said openings inside the cartridge.  The flexible shutter can be slid between an open position where both openings are exposed and a closed position where both openings are covered for protecting a tape in the cartridge.  The flexible sliding shutter has a flexible bifurcated detent such that in a closed position of the shutter the detent is positioned along a second side wall closer to the front wall while in the open position of the shutter it is positioned along the second side wall closer to the back wall.  The bifurcated detent has pawls at its bifurcated end which, in the closed position of the shutter, engage the guide locking the shutter closed.  To play the tape, the tape cartridge is inserted into a cartridge housing of a tape cartridge player with the front wall being a leading plane.  A shutter opening member of the player engages the bifurcated detent on the shutter, flexes the free bifurcated ends inwards to unlock the shutter for sliding to the open position.  As the cartridge is being removed from a player, a shutter closing member on the player moves the shutter to a closed position.

Abstract: ABSTRACT OF THE DISCLOSURE      A furnace containing a burner, supplied by fuel to be ignited at the burner, in the presence of air, is provided with a viewing duct for viewing the flame and means for detecting the radiation intensity at a plurality of different wavelengths of the radiation spectrum.  The output from the detector is amplified and integrated and a signal representing the ratio of intensities at the selected wavelengths is applied to an indicator to indicate fuel-air ratio and also is applied to control means for the fuel flow or the air flow, or both, to control the fuel-air ratio at the burner and to maintain it substantially constant at a desired value.  This can be done at more than one burner, providing balanced furnace operation.  With this balanced furnace, there is improved firing efficiency, resulting in fuel saving and lowered pollution emissions.  A computer type master con-troller can be used to correlate the fuel-air ratios for the individual burners.
