Abstract: ABSTRACT OF THE DISCLOSURE         An endless power transmission belt comprising a plurality of V-belt parts spaced laterally apart from one another and tie band having an improved structure and connecting the V-belt parts together.  The V-belt part and the tie band are essentially made of elastomer material and fabrics.  More specifically, the tie band is made up of at least two cord fabric layers and an elastomer material in which the cord fabric layers are embedded.  An intermediate elastomer material layer is provided between the fabric layers.  The fabric layers are made of cords which are extended obliquely with respect to the longitudinal axis of the belt in such a manner that the cords forming one fabric layer form an angle with the cords forming another fabric layer adjacent thereto.  The upper surfaces of the plurality of V-belt parts are connected by the tie band thus constructed, to form one unit.

Abstract: TITLE           A METHOD OF CASTING A REVERSE OSMOSIS OR             ULTRAFILTRATION POLYMERIC MEMBRANE       INVENTORS Oleh Kutowy William L. Thayer Srinivasa Sourirajan ABSTRACT OF THE DISCLOSURE In the method of casting a reverse osmosis or ultrafiltration polymeric membrane on a wall of a porous support having a first and a second side, wherein the first side is coated with a cellulose ester casting solution to at least partially impregnate the support, solvent carrier of the casting solution is partially evaporated to leave a residue, and then the residue gelled with a gelation liquid, the improvement comprising the residue adjacent with the second side is gelled with a relatively-larger-pore-forming gelation liquid to that used to gel-residue adjacent the first  side, the relatlvely-larger-pore-forming gelation liquid having a monohydric alcohol mole fraction content of at least 0.1.          This, together with particular temperatures for the gelation liquids, causes relatively larger pores to be formed towards the second side of the porous support which do not provide such a undesirable impediment for, for example, water flux on the low pressure side of the membrane under service con-ditions.  The method is particularly useful for casting tubular, polymeric membrane anchored to the inner surface of a porous, tubular support and where the relatively larger pores are adjacent the outer surface of the porous support.

Abstract: APPARATUS FOR USE IN CONJUNCTION WITH BOILER FLUE GASES FOR GENERATING INERT BLANKETING GASES                 ABSTRACT OF THE DISCLOSURE      Apparatus for use in conjunction with boiler flue gases, for generating inert blanketing gases, for safety in the pumping out of hydrocarbons or other flammable liquids from tanks or containers, such as might be used on board ship while unloading liquid fuels, etc.  The apparatus com-prises a circular vessel with a vertical axis.  Coaxial with the outer wall of the vessel is an inner refractory wall of lesser diameter, which houses a combustion zone.          Liquid fuel is supplied under pressure axially at the top of the combustion zone and, with atomizer means, a spray of liquid fuel droplets is projected downwardly in the com-bustion zone.  Flue gases from a boiler or similar source is supplied, along with combustion air from a blower, to a plenum upstream of the fuel spray.  This provides a down-going flame inside of the combustion chamber, which flows downwardly, past the bottom edge of the refractory wall, and upwardly in the annular space between the refractory wall and the vessel wall.  A downward spray of water drop-lets from a plurality of nozzles in the annular space serves to clean and cool the hot gases, which flow upwardly in the annular space, past a demisting means, to the tank or other receiving device, which is to be filled with the blanketing gas.

Abstract: ABSTRACT OF THE DISCLOSURE           A device is disclosed for measuring the frequency of a pulsed carrier signal in which the carrier frequency is situated within the frequency range and to give a continuous signal whose frequency is equal to the measured carrier frequency.  A frequency discriminator gives an analog voltage via a track-and-hold circuit and a DC-amplifier to one input of a comparator whose second input receives the analog voltage from the discriminator.  The difference value from the comparator is supplied to a voltage controlled oscillator.  This is via a directional coupler and a controllable switch connected to the frequency discriminator which alternatively receives the input signal to the device and the output signal from the voltage controlled oscillator.

Abstract: ABSTRACT OF THE DISCLOSURE Halides of Si and Ti, B, P, or Ge and oxygen or steam are introduced into a reaction vessel and heated in a vapor phase to form fine glass particles by oxidation or hydrolysis.  The fine glass particles are deposited on a substrate.  The deposited fine glass particles are heated and vitrified into a transparent glass layer, which is etched to form a core having a desired pattern by a reactive sputter etching process using Freon* gas.  The core is coated by a clad.  In a waveguide thus formed, a cross sectional configuration and dimensions of a core layer and a refractive index difference are precisely controlled. The waveguide is manufactured with good reproducibility. The fabrication method is suitable for mass production of waveguides.  An expansion coefficient transient layer is provided between the core layer and the substrate to prevent cracks in the waveguide.  The glass softening temperature of the cladding layer is set lower than that of the core layer, so that the cross sectional configuration and dimensions of the core layer is unchanged against the heat in vitrification process of the cladding layer.  The refractive index is reduced in the vicinity of the boundary between the core and clad to prevent the loss of light due to light scattering on the core side faces.
