Abstract: Abstract of the disclosure:           A one side coated metal of excellent appearance and quality can be obtained by dipping the material into a coating bath.  In this case, one side of the material is oxidized just before it enters the bath so as to form an oxide film on that side and leave it uncoated. As soon as it is pulled up from the bath it is maintained under a non-oxidizing atmosphere so as to prevent adherence of the coating metal to the oxide film.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus and method for chemically altering and scrubbing the noxious constituents from foundry core manufacturing and arc welding operations is disclosed.         An upstanding closed container is provided and a gas washing liquid is disposed within the container to a predetermined level.  A horizontal baffle is mounted stationarily within the container at an elevation spaced slightly above the level of the gas washing liquid therein and spaced peripheral portions of the baffle are spaced inwardly of the opposing inner surface of the container.  A gas drive pipe extends into the container, downwardly past the baffle, and opens downwardly in a central lower portion of the container, below the baffle and near the bottom of the liquid.  The container includes a top cover and an outlet duct is provided which opens outwardly of the container through a central portion of the cover.  The gases are pumped into the drive pipe to achieve a critical velocity at the exit of the drive pipe  of about 900-6000 linear feet per minute.         Entering the liquid in a substantially vertical downward direction within the critical velocity range, small gas-containing bubbles, on the order of 1/8-3/8 inches is diameter, are formed as the gas stream rises, which bubbles impact against the horizontal baffle.  The high velocity gases impart sufficient kinetic energy to the system to enable the necessary chemical reactions and scrubbing to proceed.

Abstract: ABSTRACT OF THE DISCLOSURE            A method of making a dynamically balanced cup-shaped blank for use in the production of a V-grooved pulley form a flat sheet metal disc by flow forming the metal with an improved metal spinning roller construction. The disc is mounted on rotating die means between headstock and tailstock die forming assemblies of a spinning machine. A first spinning roller pressure shear forms and thins an intermediate annular portion of the disc along a con-ical surface of the headstock die to form a conical wall of the cup-shaped blank, with an unworked outer annular portion of the disc extending outwardly of the conical wall. A plurality of the improved rollers are moved axially along and parallel with the headstock die means in a single pass. Outer curved front said surfaces of the rollers lay the outer unworked annular portion of the disc along a cylindrical surface of the headstock die form without materially reducing the metal thickness to rough form a cylindrical wall of the cup-shaped blank. This cylindrical cup wall then is immediately thinned and elongated along the cylindri-cal surface of the headstock die by a first metal deformation zone formed on each of the rollers.  The depressed metal is permitted to expand slightly into a relief zone formed on each of the rollers immediately rearwardly of the first metal deformation zone.  This expanded metal is immediately thinned further by a second metal deformation zone formed on each of the rollers.  The metal then is immediately burnished and again expanded slightly outwardly to facilitate its removal from the headstock die by a second metal relief zone or burnishing surface formed on the rear of the rollers.       The improved roller has a front face and a curved sur-face extending rearwardly axially therefrom.  A first conical sur-face extends rearwardly outwardly from the curved front surface forming a first metal deformation zone joined immediately inte-grally with the curved surface.  A rearwardly inwardly extending first metal expansion zone forms a fist corner at the junction with the first metal deformation zone, with the corner having a radius greater than any radius of a point of the curved front sur-face.  A second conical surface extends rearwardly outwardly from the first expansion zone forming a second metal deformation zone. A rearwardly inwardly extending second metal expansion zone forms a second corner with the second conical surface, with the second corner having a radius measured from the axis of the roller great-er than the radius of the fist corner.

Abstract: FLUID ACTUATED DEVICE                 Abstract of the Disclosure A fluid actuated device of the type wherein the con-trolled supply and discharge of fluid medium actuates a member for movement through an orbital path in which the flow of the fluid medium is controlled solely by a valve structure rotat-ing in synchronism with a member rotatively driven by said orbitably moving member and which control selectively permits the supply of fluid medium to bypass the orbitably movable member.        Fluid actuated devices utilizing an orbital member are well known and one type of such device is commonly referred to as orbit motors.  Prior orbit motors have employed various structures to control the supply and discharge of fluid medium which have required a number of cooperable members to be precision machined to obtain the tolerances necessary to permit operation of the motor.  With such precision components the prior motors have been limited to utilizing high quality lubricating fluid to obtain reasonable motor life.  Further the output of such prior motors has been limited for a given set of components and different sets of precision component are required to obtain a range of power outputs for the orbit motor.  Also various designs of such prior orbit motors have required that various portions of the enclosing housing and various internal components be exposed to the pressure of the supply fluid which due to the higher pressure involved has required that the housings and components be sectioned to withstand such higher pressure.  Still other types of fluid actuated devices utilizing an orbital member such as pumps are well known and have the same disadvantages as set forth above.

Abstract: ABSTRACT            Light fuel oil of low viscosity (approx.  20C < 2 E) is supplied to a pressure atomizing oil burner. A flow heater which is positioned upstream the pressure atomizing nozzle preheats the fuel oil up to a temperature of approximately 150C but not over the coking andcracking temperature of the fuel. With heat efficiencies up to approximately 25 000 kcal/h density and viscosity are continuously d-ecreased in the flow heater in order to reduce the thickne-s of the oil film leaving the atomizing nozzle and thus to decrease the flow rate by weight per hour. With heat efficiencies higher than approximately 25 000 kcal/h density and viscosity are decreased before the ignition phase by preheating, in order to reduce the thickness of the oil film flowing out of the atomising nozzle and thus to decrease the flow rate by weight per hour in the following ignition phase. After the ignition phase the preheating will be reduced or stopped.

Abstract: PROTECTIVE DEVICE FOR RAILROAD SIGNALING APPARATUS        ABSTRACT OF THE DISCLOSURE    The receiver of an audio frequency (AF) track circuit for a track section of an electric propulsion railroad is coupled across an associated impedance bond by the primary and secondary windings of a saturable transformer.  The control winding of this transformer receives energy signals from a voltage com-parator network which compares input signals from two pick up coils, one positioned in inductive relationship with each rail at the receiver end of the section.  These coils are tuned to respond to a selected ripple characteristic of the rectified DC propulsion energy, e. g., the sixth harmonic of the basic AC power supply source.  When the propulsion currents, and particularly the selected ripple characteristic, in the two rails are unequal, due to a broken rail, intervening ground, or other fault condition, unequal input signals from the coils actuate an output from the comparator which energizes the control winding, thus saturating the transformer core to uncouple the primary and secondary windings to interrupt the coupling between impedance bond and track receiver to register and hold a section occupancy indication, a fail-safe condition.

Abstract: ABSTRACT     A clutch for coupling an engine to a transmission gearbox engages and disengages automatically in response to engine speed variation.  Springs hold the clutch pressure plate retracted from the clutch discs at idling speeds.  As engine speed increases, centrifugally generated fluid pressure in the clutch lubricant overcomes the spring force and applies a modulated engagement pressure to the discs.  An internal valve continuously supplies an oil flow to lubricate and cool the clutch components and to charge the centrif-ugal pressure-generating means.  Retraction of the pressure plate shifts the valve to reduce the oil flow while the clutch is disengaged.  This reduces viscous drag within the clutch and thereby assures a more controlled dis-engagement.  Retainer means stores some of the reduced oil flow to assure that ample fluid is available to the centrifugal pressure-generating mechanism when engagement commences.
