Abstract: CRYSTALLINE ZEOLITE AND             PROCESS FOR PREPARING SAME     ABSTRACT OF DISCLOSURE     A novel synthetic crystalline zeolite denominated zeolite "Phi" is prepared hydrothermally from aqueous gels in the [N(CH3)4]2O - Na2O - Al2O3 - SiO2 system.  As synthesized, the zeolite exhibits large-pore adsorption characteristics, a characteristic X-ray powder diffraction pattern and a composition expressed in moles of oxides as:   0-02 - 0.05 [N(CH3)4]2O ? 0.95 - 1-05 Na2O ? Al2O3 ?   4-7 SiO2 ? 0-6 H2O.            Because the pores are large enough to admit aromatic organic molecules, the zeolite is suitable as a catalyst base in aromatic alkylation processes.

Abstract: A B S T R A C T Water vapor generated in concentrating an aqueous urea solution and containing a small amount of aqueous urea solution mist, ammonia and carbon dioxide is treated to recover urea and ammonia values.  The water vapor is introduced into a separator wherein all of the urea solution mist is separated together with a part of the ammonia and the carbon dioxide to form a first condensate.  The water vapor is then fed into a surface cooler wherein the water vapor is indirectly cooled to form a second condensate.  The first condensate is used for process water and the second condensate is subjected into rectification to separate ammonia and carbon dioxide contained therein in the form of a mixed gas, which is recovered, from the remaining waste water free of ammonia and carbon dioxide.

Abstract: SURGE PROTECTOR                 Abstract of the Disclosure A surge protector or arrester for providing surge protection for relatively low voltage or secondary equipment, circuits and systems includes a vertically stacked, parallel arrangement of two, independent, spark gap and valve block assemblies, the components of which are generally horizontally disposed within a triangularly shaped surge protector housing.  The triangular shape of the housing enables maximum spacing of the three electrode contacts associated with the two assemblies to prevent their flashover while maintaining minimum exterior housing dimensions.  The components of the two assemblies are disposed horizontally within the housing after a sealing and insulating compound has been applied to the entrance portions of the three contacts.  Each of the three contacts includes an integrally formed crimp contact, an integrally formed lead-in electrode and an integrally formed spring contact.  A plurality of novel spark gap electrodes and a plurality of expansion chambers, spaces or reservoirs are provided within the housing to enable hot, highly pressurized, ionized gases formed during the dis-charge operation of one or both of the assemblies to expand and cool to thereby prevent flashover of two or more of the contacts.

Abstract: GAS TURBINE COMBUSTOR ARRANGEMENT     ABSTRACT OF THE DISCLOSURE         A combustor for a gas turbine is shown having a catalytic reactor element to promote low temperature combus-tion of the fuel.  An air-fuel premix chamber is provided in the upstream end of the combustor arrangement to produce a mixture which is substantially uniform throughout a plane transverse to the direction of flow of the mixture just prior to the catalytic element.  The premix chamber comprises a short cylindrical member of less diameter than the shell of the combustor and closed at the upstream end, with the opposite end discharging directly to the catalytic element.          The upstream portion of the walls of the cylinder contain apertures so that the air and fuel introduced into the upstream end of the combustor must flow axially into the annular space between the shell and the chamber, thence the flow is abruptly changed to a somewhat radial component to enter the apertures and thence the flow is again abruptly changed to an axial direction to enter the catalytic reactor.          This provides a sufficiently tortuous path to uniformly mix the air-fuel components prior to entering the catalytic element.

Abstract: Abstract of the Disclosure A clamp and related method provides for a stable fluid flow rate through a flexible tubing.  The clamp comprises a body having an anvil and a tube-constricting cam that cooperates with the anvil to pinch together diametrically opposed sections of the tubing to provide a reduced flow passageway.  The cross-sectional area of this passageway, and hence the fluid flow rate, is varied by rotating the cam to change the transverse extent of the pinched off portions.  The reduced flow passageway is constrained at each adjustment of the clamp to prevent variations in flow rate due to displacement of the material of the tubing wall.

Abstract: ABSTRACT         A current stabilizing arrangement with a first and a second current circuit in which currents with a mutually fixed ratio are maintained. These currents respectively flow through the series connection of a first semiconductor junction in series with a resistor and a second semiconductor junction.  The voltage across the second semiconductor junction is maintained equal to the voltage across said series connection, which results in currents which are linearly dependent on the temperature.  In order to add a component with a positive second-order temperature dependence to those currents so as to enable a negative second-order temperature dependence to be compensated for in the case of application in a voltage or current reference source, the current stabilizing arrangement comprises a transistor whose base-emitter junction constitutes said second semiconductor junction, the base circuit of said transistor including a resistor.

Abstract: A METHOD OF FERMENTING                Abstract of the Disclosure A method of fermenting a fermentable substrate, such as brewer's wort.  The substrate, having a high concentration of fermentable carbohydrate which would normally ferment very slowly or incompletely, is fermented by utilizing water dilution at a process point in the fermentation.  The dilution is effected after the initial foam head produced in the fermentation collap-ses so that the headspace of the fermenting vessel normally allocated for the foam can be used for the fermentation of the diluted substrate.  The water dilution reduces the osmotic pres-sure and ethanol concentration in the substrate, thus allowing the fermentation to proceed without inhibition by the combined effect of the two factors.  The reduced osmotic pressure also increases the ethanol gradient between the inside and the outside of the yeast cells to enable the fermentation to proceed to completion.
