Abstract: ABSTRACT OF THE DISCLOSURE   Two coaxial metal pipes, whose confronting extremities are each provided with a plurality of peripheral ribs of staggered height separated by two or more peripheral grooves, are intercon-nected by a coupling sleeve of fiber-reinforced thermosetting resin subdivided into several coaxially interleaved and independent ly deformable cylindrical shells each terminating in a pair of internal beads engaged in a respective pheripheral pipe groove. The shells, increasing in axial tensile strength from the innermost to the outermost one, are preferably separated from one another by interposed antibonding layers of thermoplastic resin.  A resino? filler can be inserted between the pipe extremities for electricall insulating them from each other.  The shells of the coupling sleeve can be formed by coiling resin-coated filaments around the pipe axis, advantageously with application of an antifriction layer on each inner shell before the thermosetting material thereof has been fully hardened.

Abstract: ABSTRACT OF THE DISCLOSURE           A package making machine of the vertical form, fill and seal type has an improved electrical control system operable on demand irrespective of the intervals of time between a train of cycle start signals and operable independently of the mech-anical power source for the machine and/or its associated product feeder.  The machine has a tube feeder operable during a portion of each bag making cycle and an end sealer operable during another portion of each cycle.  Side sealing is accomplished during feeding by a hot belt sealer and secondary operations include a jammed product dislodging plunger, an air blast, a code dater, and a bag cut-off knife.  All of the foregoing are operable by the control system in timed relationship and the system is also capable of controlling a product dump device in the product feeder.  The tube feeder is controlled by an adjus-table timer or by a photoregistration circuit which reads marks printed along the length of the web from which the package tube is made.  When photoregistration feeding is used, the feed timer operates as an override to shut down the system on failure of one or more registration marks.  The end sealer is controlled by an adjustable timer as are all secondary operations.  A timed overheat device is operable to remove the hot belt sealer from the tube.  Independent adjustment of all operations in their timed relationship and duration of operation is possible as well as adjustment of overall cycle time.

Abstract: PROCESS AND APPARATUS FOR PURIFYING    SEA WATER BY REVERSE OSMOSIS     ABSTRACT OF THE DISCLOSURE           Sea water is purified by reverse osmosis in an offshore installation wherein sea water is withdrawn from the sea by a low pressure pump and passed through plural-stage physical filters having decreasing degrees of porosity to remove suspended particles and colloids from the sea water.  The thus filtered sea water is then fed by a high pressure pump, at a controlled pressure above the osmotic pressure of the sea water to a reverse osmosis module, wherein a portion of the sea water permeates through a semi-permeable membrane of the module to form purified potable water, and wherein the remaining sea water, having the dissolved salt concentration thereof increased, is discharged back to the sea.  The reverse osmosis module is operated such that the conversion level, measured in percent and equal to the volume of purified water divided by the volume of sea water fed to the module, is maintained below a maximum value to prevent the formation on the semi-permeable membrane of the module of sulfates and carbonates.
