Abstract: ABSTRACT OF THE DISCLOSURE               A condenser for separating solvent vapors from non-con-densable gases. The condenser includes an outer shell, a middle shell inside the outer shell, end an inner shell inside the middle shell. The shells are coaxial and the middle shell is open at the bottom. Mixed solvent vapors and non-condensing gas pass downwardly through an annular space between the inner and middle shells. There is a condensate receiving chamber in the outer shell below the lower end of the middle shell. A cold trap is mounted in the upper portion of the condensate receiving chamber. Coolant is introduced into the cold trap to cool the cold trap.          Helical tube means mounted on the cold trap receives the coolant from the cold trap. The helical tube means extends upwardly through the annular space between the inner and middle shells and discharges into an upper portion of the inner shell, and is removed from the inner shell.          Condensate is withdrawn from the chamber in the lower portion of the outer shell. The non-condensable gas passes upwardly from the lower end of the middle shell through an annular space between the middle shell and the outer shell into a collecting space in an upper end portion of the outer shell. The non-condensable gas is withdrawn from the collecting space.

Abstract: ABSTRACT OF THE DISCLOSURE     A torque transmission device is provided wherein a rotary housing is connected to one of front and rear drive shafts which respectively drive front and rear axles of a four-wheel drive vehicle, while a rotary shaft coaxially carried by the rotary housing is connected to the other of the front and rear drive shafts.  The housing receives therein a multiple disc clutch device for transmitting rotational power between the housing and the shaft through friction engagement between alternately arranged outer and inner clutch discs which are respectively rotatable bodily with the housing and the shaft.          The housing also receives an axially movable piston to press the clutch discs for friction engagement.  An end wall of the housing or an end cap secured thereto and a facing end surface of the piston define an axially narrow circular chamber, within which a rotor with several radially extending blade portions is received to be rotated by the shaft.  A several space sections into which the chamber is divided by the rotor blade portions are filled with silicon oil of a high viscosity.  When the rotational speed difference occurs between the rotor and the housing, a pressure is generated within each of the space sections thanks to the high viscosity of the silicon oil and is directly applied to the piston, whereby rotational power is transmitted from the housing to the rotary shaft and vice versa.

Abstract: FLUSH VALVE/FLUSH TUBE CONNECTION     Abstract of the Disclosure A connection between the outlet of a flush valve and a flush tube includes an outlet fitting for the flush valve having an exterior thread thereon and a flush tube which extends within the outlet fitting.  A coupling nut having an interior threaded area for attachment to the fitting also has an inwardly-directed annular shoulder which extends closely adjacent the flush tube and with the end of the fitting, defines an annular chamber.         Positioned within the annular chamber is an annular elastomeric gasket in contact with an end of the fitting and in peripheral contact with the flush tube.  A back-up ring is posi-tioned within the chamber for circumferential contact with the gasket and a clip ring is positioned within the chamber between the back-up ring and the coupling nut shoulder and is adapted for surface penetration engagement with the exterior of the flush tube.  As the interiorly threaded coupling nut is advanced on the exteriorly threaded fitting, the size of the chamber is reduced and the gasket and back-up ring move the clip ring into surface penetration of the flush tube to secure the flush tube to the fitting. The gasket is distorted into sealing contact with the flush tube, back-up ring, fitting and the interior of the coupling nut.

Abstract: "Carrier-to-Noise Detector for Digital Transmission Systems"                    ABSTRACT OF THE DISCLOSURE A carrier-to-noise detector comprises an A/D converter (1) which samples an output of the demodulator of a digital transmission system at a symbol clock rate and converting it to a digital signal having positive and negative values. An absolute value converting circuit (2) converts the output of A/D converter into an absolute value which is averaged by a first averaging circuit (3) over a period sufficient to suppress short term variations and then squared by a first squaring circuit (4) to give an output representing the carrier component. The output of A/D converter is, on the other hand, squared by a second squaring circuit (5) and averaged by a second averaging circuit (6) to suppress short term variations to give an output representing a total of the carrier and noise components. The carrier component in the output of the second averaging circuit 6 is subtracted by a subtractor (7). A ratio between the outputs of the first squaring circuit (4) and subtracting circuit (7) is derived by a divider (8) as a representation of a carrier-to-noise ratio.

Abstract: Slack waxes and synthetic wax are isomerized and processed into high viscosity index and very low pour point lube base stock oils and blending stocks by the process comprising the steps of hydrotreating the wax, if necessary, to remove heteroatom and polynuclear aromatic compounds and/or deoiling the wax, if neces-sary, to an oil content between about 5-20% oil, isome-rizing the wax over a Group VI-Group VIII on haloge-nated refractory metal oxide support catalyst, said isomerization being conducted to a level of conversion such that         about 40% and less unconverted wax remains in the 330°C+, preferably the 370°C+ fraction sent to the dewaxer.  The total isomerate from the isomerization unit is fractionated into a lube oil fraction boiling at 330°C+, preferably 370°C+. This oil fraction is solvent dewaxed preferably using MEK/MIBK at 20/80 ratio and unconverted wax is recycled to the isomeriza-tion unit.  Operating in this manner permits one to obtain isomerate oil of very high VI (in excess of 130) possessing low pours (-21°C, preferably -24°C, most preferably -27°C).
