Abstract: ABSTRACT OF THE DISCLOSURE     The invention contemplates a seal construction as for use between relatively rotating parts such as the inner and outer race rings of an antifriction bearing.  In such an application, the end of the inner ring is rabbeted to define a cylindrical land and a generally frusto-conical shoulder near one axial end of the raceway, and the outer ring may be conventionally formed for swedged or crimped reception of an annular metal seal cap assembled thereto.  The cap metal is formed with an inward skirt having radial-clearance relation to an axially outer portion of the land, and an elastomeric seal member is bonded to the axially inner face of the cap metal, at a location radially offset from the inner edge of the skirt.  The seal member comprises a body of provide substantial axially inward offset for suspension of a seal lip, integrally formed with the body and projecting inwardly to an extent having interference with the land, so that when assembled to the land the lip is in axially extensive and circum-ferentially continuous light resiliently loaded running contact with the land, and so that the bend of the lip near connection with the body is in closely nested, inversion-protecting adjacent to the frusto-conical shoulder.

Abstract: ABSTRACT OF THE DISCLOSURE     The relative rate of flow of each component of a two-phase gas/liquid flow is measured by a process wherein a process for measuring the rate of flow of each component of a composite fluid comprising a liquid and a gas flowing in a conduit wherein successive fractions of unit volume of the said flow are isolated at a reference pressure per unit of time, the volume of each fraction is varied so that either the volume or the pressure attains a predetermined value, the corresponding variation in the pressure or the volume respectively of the fraction is measured and from this variation, the relative amounts of each component in the fraction and hence the rate of flow of each component is deduced.  Apparatus for such a process includes a volumetric arrangement having a chamber and a rotating means in the chamber and arranged to delimit a number of cells whose volume varies during each rotation, and pressure pick-ups disposed to measure pressure changes therein.

Abstract: Title of the Invention WIND ELECTRIC PLANT                 Abstract of the Disclosure A multiblade, wind-driven, variable pitch propeller is used in a wind electric plant for the generation of electrical power from wind forces, and the propeller is rotatable in a plane at an angle to the tower axis, thus pre-senting a better angle of attack to prevailing wind forces and at the same time enabling larger propellers to be used without propeller-tower interference and also reducing the distance between the propeller and gear case.  A snubber arrangement is provided on the propeller blade return springs to slow the governor action and prevent abrupt pitch changes and damaging flutter of the blades, and a self-centering, double-action pivot washer is provided between the propeller blades and the return springs to ensure free pivoting and long life of the spring connecting bolts.  Easily adjustable positive blade stop bolts are engaged directly between the hub and the propeller blades to limit return movement thereof and the propeller hub-return spring connection includes a laterally movable spring bracket which enables the propeller blades to feather in the event one or more return springs is broken or otherwise rendered inoperative.  The gear case center, ring gear and axis of propeller rotation are offset laterally from the axis of the tower and pinion gear, to balance torque forces generated at the gears with wind forces on the propeller, and in one form of the invention, the pinion gear is located near the top of the gear case and the pinion gear shaft is surrounded by an oil seal sleeve, thus removing the pinion gear and shaft from the frictional drag of the gear lubricant and eliminating the need for an oil seal between the pinion shaft and gear case.

Abstract: ABSTRACT OF THE DISCLOSURE          Mixed ester products obtained by treatment of a triglyceride derived predominantly from C12 to C18 fatty acids under transesterification conditions with a polyoxyalkylene glycol having an average molecular weight less than 2000 and a high molecular weight aliphatic or cycloaliphatic dicarboxylic acid containing 18 to 54 carbon atoms, e.g., polymer acids, are useful metal working fluids.  The modified triglycerides exhibit enhanced thermal stability and can be used either in neat form or in solution.  They are readily compatible with water to provide stable aqueous emulsions and dispersions having superior lubrication properties.          When coated into aluminum or aluminum alloys, they provide a surface which is essentially free of surface stain and is resistant to subsequent water stain.

Abstract: ABSTRACT OF THE DISCLOSURE             A radial axle railway truck has a pair of wheel and axle assemblies with profiled wheel treads of greater than conventional conicity to steer the assemblies by means of the differential effect of the inner and outer wheel diameters on curved track, the axle bearings are located inboard of the wheels, and the truck frame side members are correspondingly located inboard of the wheels and there supported on the axle bearings such that longitudinally acting resilient restraint means between the axle bearings and the truck frame resist sub-stantial movements of the axles longitudinally of the truck frame while offering only limited resistance as a couple to steering movements of the axles with respect to the truck frame because of the relatively short transverse moment arm between the longitudinally acting resilient means.  The inboard loca-tion of the axle bearings permits the use of straight links extending diagonally of the truck and pivotally connected at their ends to the diagonally opposite axle bearings to oppose hunting movements of the wheel and axle assemblies during movement along tangent track and to couple wheel-induced turn-ing movements of the wheel and axle assemblies in opposite directions on curved track so as to avoid interface with their self-steering ability.  An equalized tread brake mechan-ism is provided to compensate automatically for the differences in longitudinal wheel spacing at the opposite sides of the truck on curved track.  In a preferred form, the truck frame itself carries outboard springs yieldable in shear longitudi-nally and laterally of the truck, as well as vertically, to accommodate swivel and transversely of the truck to cushion the body from lateral track irregularities, the springs being adapted to support the car body directly, and a compatible longitudinal force-transmitting means, capable of accommodating vertical, lateral and swivel movements between the truck and car body, is provided between the truck frame and the supported car body.
