Abstract: ABSTRACT OF THE DISCLOSURE          Reverse osmosis, particularly for water desal-ination, is achieved using semipermeable membranes which selectively permeate purified water from a feed solution pressurized by reciprocating piston or diaphragm pump. Pump action is assisted by returning pressurized concentrate fluid acting on reverse side of the pump piston or dia-phragm.  Directional valves controlling alternating admis-sion and venting of concentrate fluid to and from pump cylinder are actuated mechanically by reversal of force applied to the piston rod.  Mechanical dwell is provided in the piston or diaphragm motion during directional valve actuation.  Pump may be operated by a manual lever or by a crank mechanism on a low speed rotary shaft.  An optional differential surge absorber provides continuity of feed solution circulation past membrane surfaces during the return pump stroke, thus minimizing detrimental salt concen-tration build-up on the membranes.

Abstract: IMPROVED HYDROCARBON REFORMING PROCESS WITH HYDROCARBON HAVING EXCESSIVELY HIGH SULFUR CONCEN-TRATIONS                ABSTRACT OF THE DISCLOSURE     A hydrocarbon reforming process minimizing the detrimental effects of inadvertently contacting a platinum group metal, halogen-containing catalyst with feedstocks containing undesirably high concentrations of sulfur and water.          The present process involves adding a sufficient amount of halogen component to the reaction zone to maintain or increase the catalyst halogen concentration during high sulfur, high water-containing feedstock-catalyst contacting.  After the sulfur contamination has been removed from the catalyst, normal hydrocarbon reforming is resumed.  Maintaining or increasing the catalyst halogen concentration provides for substantially reduced permanent loss in catalytic activity caused by such high sulfur, high water-containing feedstock-containing contacting.

Abstract: ABSTRACT OF THE DISCLOSURE         A digital tape timer containing a counter and associated arithmetic control and timing logic to detect the relative tape position and provide a time-multiplexed, binary coded decimal (BCD) output for the display of the tape position in hours, minutes, seconds and/or tenths of seconds of play/record time at any of the selected tape speeds. The timer employs an eight digit format; five digits are dis-played and one of the three remaining digits becomes the least significant digit whose modulus is altered to present the correct division rate to the incoming tach pulses.  The counter generates serial digits with one digit appearing on a selected clock line, whereby all eight digits are transmitted using four wires for the binary code plus one wire for selection of each digit to be displayed   Thus, the septum inherently provides the added advantage of time-multiplexing of the timer system output.  The pre-division of the tach pulses using the LSD provides division which instantly and accurately follows the counting direction.

Abstract: ABSTRACT In a method and apparatus for the high speed grinding of gearwheels from a peripherally unprepared, cylindrical blank, rough grinding of a tooth profile is performed simultaneously with finish grinding of a neighbouring tooth profile.  During rough grinding a substantial volume is removed from the periphery of the blank, so that finish grinding of this rough ground tooth profile, after indexing of the blank by one tooth pitch, takes place at a relatively low rate of material removal and without great pressure. Rough-and finish-grinding are carried out with a single appropriately pro-filed grinding wheel during intermittent indexing of the blank.  The grinding wheel performs a working stroke parallel to the central axis of the blank and grinds to finished size the right and left flanks of neigh-bouring teeth as well as the root between these flanks, while at the same time the flank profile of the succeeding tooth the direction of indexing is rough ground, whereby after rotation through 360° the tooth profile part serving as starting point or datum point is finish ground.  The rough grinding removes about 90% of the flank material to be ground away.

Abstract: PROUDUCTION OF CARBON MONOXIDE BY THE     Abstract An increased amount of carbon monoxide is produced in a process for the gasification of carbonaceous materials by employing a reverse water gas shift reaction in the process.  Raw gas produced by the gasification of carbo-naceous materials contains predominantly carbon monoxide and hydrogen along with hydrogen sulfide, carbon dioxide, water and methane.  Carbon dioxide is separated from the raw gas as is the hydrogen sulfide.  Thereafter, the carbon monoxide is separated from the raw gas to yield one portion of the carbon monoxide product gas.  After the removal of carbon monoxide the raw gas con-sists of a hydrogen-rich gas.  The hydrogen-rich gas which may be purified is mixed with the previously separated carbon dioxide along with any imported carbon dioxide and along with a recycle gas from a catalytic reaction loop. This mixed gas is conveyed to a heat exchanger in the catalytic reaction loop and passed through a heat exchanger located immediately after the gasifier through which the raw product gas passes.  In the heat exchanger the hot raw ` product gas indirectly contacts the mixed gas and transfers some of its sen-sible heat to the mixed gas to effect the catalytically promoted, endothermic reaction of carbon dioxide and hydrogen to produce a carbon monoxide-containing gas.  The indirect contacting for heat exchange is conducted in a manner that limits the accumulation of elemental carbon from any of the carbon-containing components of the mixed gas.  The carbon monoxide is separated from the other components of the carbon monoxide-containing gas to yield a second portion of carbon monoxide gas which is then combined with the first portion of carbon monoxide product gas to give the increased amount of carbon monoxide product gas.

Abstract: ABSTRACT An overflow return tank is disclosed, especially for receiving return fuel in internal combustion engines with a fuel gauge.  A receptable has an inlet located at the top for return flow and an outlet and an air bleed hole.  A float is located within the receptacle for controlling a valve located at the outlet of the receptacle.  The valve comprises a soft, elastic diaphragm, which is connected to the float and upon lifting of the float gradually exposes the outlet by being bent, so that fuel can be taken out from the overflow return tank.  Owing to the design of the valve only a small lifting force from the float is required, whereby the fuel amount in the overflow return tank can be maintained substantially constant even with great variations in the return flow.  The overflow return tank, besides, can be given small dimensions.  The overflow return tank further is provided with a member to separate gas bubbles from the incoming return flow before the fuel again is discharged from the overflow return tank.  Said member may be a pipe of fabric, through the walls of which the return flow can pass.
