Abstract: MODULATING PRESSURE OPERATED PILOT RELIEF VALVE     Abstract of the Disclosure A main valve includes a product pressure  inlet, an  outlet,  a  movable  closure member and a pressurized head volume above the closure member.   Product  pressure relief  flow  through  the  main valve is controlled by a modulating, pressure operated  pilot  relief  valve  that includes  a  piston  chamber  with a reciprocally mounted pilot piston.  The chamber is in fluid communication with the pressurized head volume and with the outlet and inlet of the main valve.  An inlet valve controls flow from the inlet  of the main valve into the chamber and is actuated by the pilot piston.  A vent valve is mounted within  the piston  chamber  and  controls fluid flow from the piston chamber to the outlet of the main valve and  is  actuated by the pilot piston.  The pilot piston includes first and second  surfaces  and  effective  areas  exposed  to  the pressure  in  the piston chamber and an end isolated from the piston chamber and in fluid  communication  with  the main  valve  inlet.   A field test valve is also included with an inlet for the introduction of test pressure.  The test valve includes a first outlet in fluid communication with the inlet and a poppet  valve  mounted  between  the inlet  and  first  outlet.   The field test valve further includes a second outlet in fluid communication with  the field  test  inlet  and  the  inlet of the main valve.  A shuttle valve is positioned within the test valve between the field test valve inlet and second outlet.

Abstract: At an installation comprising a roll stand having at least one roll of the variable camber type, comprising a fixed support and a casing carried by at least three jacks and rotationally movable about the support, the pressure of the fluid in each of the jacks (14), the position of the pistons of these jacks, the speed of rotation of the roll, and the flatness and thickness of the flat product are measured. The position of one of the jacks (14b) is controlled by the thickness measurement. The pressure in the other jacks (14a, 14c, 14d, 14e) is controlled by the pressure in the one jack (14b). The positions of the end jacks (14a and 14e) are compared and the pressure in the jacks (14) is modified in order to bring the tilt of the roll to a suitable value. The deformation of the fixed support is calculated and the shape of the generatrix of contact of the roll is determined. The pressure in the jacks (14) is modified in order to bring the generatrix to a reference shape. The invention is particularly applicable to four-high rolling mills having variable camber supporting rolls.

Abstract: Switch Current Sensing With Snubber Current Suppression in a Push-Pull Converter Abstract A push-pull converter has transistor power switches which conduct alternately to con-nect a DC source with the primary windings of an output transformer.  A turn-off snubber circuit is connected with each power switch.  When a power switch is turned on, snubber current pulses flow in the circuits connected with both switches.  A switch current sensor circuit has a current trans-former with an output winding inductively coupled with each of the conductors connected between the power switches and the primary windings of the out-put transformer.  The snubber current pulses through the conductors are 180° out of phase and are sup-pressed in the current transformer output.  The switch current signal from the secondary of the current transformer is free of snubber current pulses and is used in a flux balance circuit and in a pulse-by-pulse current limiter.

Abstract: ABSTRACT OF THE DISCLOSURE    A combined brake cylinder/air reservoir device in which a relatively small, tubular-shaped piston in a positioning chamber is connected to a larger power piston having an application chamber on one side and a release chamber on the other side in which air is stored in place of separate reservoirs.  A replace-able cylinder liner is provided to receive different-sized power pistons.  During a brake application, the power piston enters the cylinder liner and is displaced from the liner during brake release to provide free air flow between the application and release chambers and thereby facilitate piston return movement by means of a return spring.  A dynamic pressure seal between the application chamber and positioning chamber engages the outer periphery of the tubular-shaped small piston, while a smaller diameter dynamic pressure seal between the release chamber and atmosphere engages the inner periphery of the tubular-shaped small piston.  This permits the seals to be located longitudin-ally in the same general area by nesting them, one within the other, thereby permitting the piston stroke to be increased without greatly increasing the longitudinal dimension of the cylinder/reservoir device.

Abstract: ABSTRACT OF THE DISCLOSURE:           When a light emitted during the irradiation by a laser beam onto the surface of steel is spectrally se-parated and elements contained in the steel are analyzed quantitatively:  an infrared pulse laser beam irradiates a sample such that an energy density on the surface of the sample becomes 2.0 x 109 W/mm2 or more, so that a satisfac-tory emission spectrum can be obtained; a light emitted from the surface of the sample is received through a path held under an atmosphere of inert gas by a light introducing system at a solid angle of 16 degrees or more, and there-after, caused to form its image at an inlet slit of a spectroscope so that an emission spectrum intensity being low in variations can be obtained for a long period of time; and out of light emitted from the surface of the sample immediately after the irradiation by the laser beam, a firstly emitted light generating white noise is excluded and a subsequently emitted light is quantitatively analyzed, so that the accuracy of analysis can be improved with the influence of the white noise being avoided.

The base material can be a sweetening agent such as a hard or soft candy base, a syrup, chewing gum, dentifrice, or the like.  The advantage of such formulations is that the unpalatable and undesirable tastes and after-tastes of unformulated zinc compound and of zinc compounds mixed with a base material are markedly reduced and the pro-ducts may be slowly dissolved in the mouth to achieve nutri-tional or therapeutic results.  Processes for the satisfac-tory preparation of the formulations are set forth.

Abstract: "APPARATUS FOR CONTINUOUSLY SEPARATING PARTICULATE           SOLIDS FROM LIQUID SUSPENSIONS"                      ABSTRACT OF THE DISCLOSURE A clarifier is provided for simultaneously treating a plurality of bodies of liquid-solid suspension in a vertically stacked fashion, with the aim of separating the particulate solids from the liquid, by process steps involving a combination of electrophoresis and reverse osmosis.  The clarifier comprises a conical shell which is mounted on a shaft for rotation.  The shaft extends through the apex of the shell and is disposed at an upward angle, so that the base of the shell is tilted. A plurality of nested, spaced apart, truncated, conical bands are secured to the inner surface of the shell.  The bands each carry an elongate anode electrode on the upper surface and an elongate cathode electrode on the lower surface.  Thus there are formed a plurality of vertically stacked, endless, arcuate treatment chambers, with an elongate anode extending along the base and an elongate cathode electrode extending along the top of each chamber.  A trough-like container closely surrounds the lower portion of the conical unit, to provide the inner wall for each treatment chamber.  The upper portion of the conical unit overhangs the container. In use, fresh suspension is fed into one end of the portion of each chamber in the container.Substantially solids-free liquid is removed from the other end of each such chamber portion.  The shell and bands are con-tinuously rotating.  Electric potential is applied to the electrodes to cause solids to deposit and dry on the anode.  When the deposits are raised by the rotating bands, to overhang the container, the deposits drop free of the conical unit, for separate recovery.
