Abstract: APPLICATION FOR LETTERS PATENT FOR      IMPROVED WATER-RESISTANT GYPSUM COMPOSITION AND          PRODUCTS, AND PROCESS OF MAKING SAME       ABSTRACT OF THE DISCLOSURE     An improved water-resistant cementitious composition and products made therefrom are provided by forming an aqueous cementitious slurry, as for example of calcined gypsum and adding to the slurry a composition in the form of an aqueous emulsion of asphalt and wax, a minor proportion of polyvinyl alcohol and a minor proportion of a borate compound, that is, one having an anion comprising boron and oxygen, as for example borax.  The slurry is set in con-ventional manner by heating and drying.  The resulting product has a high degree of water-resistance while uti-lizing less asphalt and wax composition than required with conventional asphalt-wax emulsions thereby accomplishing a large savings in raw material costs. Additionally, the use of a small amount of the borate compound permits a smaller amount of the relatively expensive polyvinyl alcohol to be used without a reduction in the water-resistance of the final product.  Alternatively, an amount of asphalt and wax composition may be utilized equal to or greater than that conventionally used, but obtaining a much greater degree of water-resistance.

Abstract: CONTINUOUS OPTICAL FIBER PREFORM FABRICATION METHOD         ABSTRACT OF THE DISCLOSURE           A refractory starting member is rotated and, at the same time, moved along the axis of rotation.  A glass raw material for the formation of the core of a porous preform and consequently an optical fiber prefrom is introduced into a high temperature portion near the tip of a high temperature burner from a nozzle for the core disposed in alignment with the center of rotation of one end face of the starting member.          The glass raw material blown out from the nozzle for the core is caused by the flames of the high temperature burner to react to produce glass fine particles, which are deposited on abovesaid end face of the starting member at the central portion thereof in its axial direction to form a porous core.          At least one nozzle for spraying a glass raw material for the formation of the cladding of the optical fiber preform is disposed opposite to the end face of the starting member but a little deviated from the axis of rotation thereof, or dis-posed opposite to the peripheral surface of the porous core.          The glass raw material for the cladding is sprayed from the nozzle for the cladding to the high temperature portion of the high temperature burner, and caused to react to form glass fine particles, which are deposited on the end face of the starting member on the outside of the porous core or on the peripheral surface thereof at the same time as the for-mation of the latter, forming a porous cladding.  The porous preform thus obtained is moved into a high temperature furnace provided on the path of movement of the preform for the vitrification thereof into an optical fiber preform.

Abstract: ABSTRACT         A solar heat-collecting structure comprises a series of interconnected transparent lenses forming a dome-shaped roof for receiving direct solar radiation and for transmitting such radiation through the lenses into the enclosure formed thereby and focusing it on a shallow tray of water forming a floor of the enclosure.  The inner surfaces of the lenses are coated with a solar radiation-reflective film so that radiation reflected from within the enclosure toward the roof is re-reflected toward the heat-collecting water surface.  Means are provided for removing heated water from the tray and replacing it with water to be heated.  Each lens in the roof lens system has a focal length dependent on its position on the roof with respect to the water surface so as to concentrate solar radiation at the water surface and thereby maximize the heating effect of such solar radiation in various sun positions.

Abstract: METHOD AND APPARATUS FOR FABRICATING OPTICAL WAVEGUIDE GRATING RESONATORS            Abstract of the Disclosure A helium cadmium laser generates an output beam of radiation which is coupled through a spatial filter and beam expander to a beam splitter which in turn provides two enlarged beams of coherent radiation of approximately equal power.  Two highly reflective mirrors are used to direct the two beams such that the two beams interfere and create the usual interference pattern in a positive photoresist layer covering an optical substrate.  A thin sheet of high index glass is held by two blocks of quartz in a position adjacent to the photoresist layer and oriented such that a part of each beam of coherent radiation is caused to pass through the high index glass before interfering with the other beam on the photoresist layer.  As a result, a grating having a quarter wavelength step or discontinuity in the middle of the grating is fabricated in the photoresist.  The photoresist pattern is then transferred to the optical waveguide by ion-beam milling.  Several high index sheets can be positioned so as to create more than a single quarter wavelength step.

Abstract: ABSTRACT A free piston engine having a pair of opposed power cylinders and pistons on a common longitudinal axis with an energy absorbing device, such as a compressor piston, being directly connected to one of the power pistons and indirectly connected to the other power piston by means of a motion reversing, synchronizing and counterbalancing mechanism on said axis. The cylinders are arranged to be fired simultaneously and due to the fact that the forces from the power pistons acting on the reversing mechanism are balanced the forces on the bearings in the mechanism are substantially reduced over those occurring in machines having cylinders that fire 180° out of phase, which results in a minimum of wear and higher efficiency due to the reduced friction The engine can also have a bounce chamber therein which gives better control and more stable operation of the power pistons than found in engines with alternately acting pairs of power pistons which do not require power piston returning means.
