A process and apparatus for elemental sulphur recovery from acid gases. By this process, acid gas, a by-product of sour natural gas from crude oil processing plants, is mixed with air and introduced to a partial oxidization furnace, and hot products of oxidization are then passed to a catalyst regenerator where elemental sulphur is vaporized. The sulphur is then recovered in a sulphur condenser, and regenerated catalyst is recycled to a catalyst contactor in a continuous flow arrangement. Also d...

A flow conditioning apparatus is connected to the inlet of a flow meter in a conduit system for conditioning the flow of a fluid supplied to the flow meter for the purpose of measurement of the flow rate. The apparatus comprises a device for uniformalizing the velocity distribution of fluid flow, and this device is combined with a vortex regulator and a flow straighter for more effectively conditioning the fluid flow.

A storage device for plate materials, particularly steel plates, has upstanding tongues between which the plates are supported edgewise on a supporting base, which base is located at an angle to the horizontal.

A digital-analogue converter comprising fluid operated elements in which a pneumatic input pulse signal is connected to a pneumatic pulse shaping circuit to limit the width and the peak value of the pulse to predetermined values and in which a means value of air pressure can be obtained through an integrating circuit.

A machine for processing articles in a container comprising a rotatable frame, a pair of container engaging members carried by the frame and themselves rotatable about an axis normal to the frame rotational axis and drive means to effect simultaneous movement of a container about both axes while exposed to processing liquid fed to the container.

In an apparatus for winding yarn on a bobbin, the yarn is distributed by a flyer which rotates about an axis that is disposed at an angle to the bobbin axis. The bobbin is rotated in a direction opposite to the direction of rotation of the flyer. The flyer moves axially relatively to the bobbin in a single direction throughout the winding period. The resulting package contains yarn that runs continuously in and out between the inner periphery and the outer periphery of the yarn package enhancing...

A method of condensing the turbine exhaust at a power plant, characterized in that the turbine exhaust is introduced into a direct-contact type condenser which works under a vacuum condition and is condensed by its direct contact with cooling water. Mixed water of the cooling water and condensed water is drawn out of said condenser, a part of the mixed water is cooled by an air-cooled heat exchanger and is further cooled by a heat exchange with liquefied gas down below a temperature correspondin...

Modification of a twin opposed cylinder two-stroke internal combustion engine according to U.S. Pat. No. 3,329,134 issued in 1967 to the present inventor, which engine has a power piston reciprocating in opposed aligned power cylinders, and an effectively integral charge piston reciprocating within aligned charge cylinders, axes of the reciprocations intersecting and being perpendicular. There are no connecting rods, the power piston is journaled on a central crankpin of a crankshaft, and the ef...

A packaging and shipping case formed of two blanks, each defining a horizontal wall panel and a pair of vertical wall panels foldably connected to the associated horizontal wall panel. One of the blanks also includes transverse securing flaps and lateral securing flaps along its perimeter, the transverse flaps to be secured to opposite edges of the horizontal wall panel of the other blank. The blanks may be formed of corrugated board with their corrugation axes perpendicular to each other, so th...

A novel procedure is provided for conducting electrolyte to, from and through an electrolytic cell. This procedure depends on maintaining the cell in a fully flooded state and using the natural pumping action due to rising entrained and/or occluded gaseous products of electrolysis to aid the passage of the electrolyte through the cell at a velocity sufficient to prevent such gaseous products of electrolysis from separating into a free gaseous phase within the cell.
