Abstract: Abstract of the Disclosure:          RECOVERY OF PHOSPHORUS FROM SLUDGE    Phosphorus is recovered from the phosphorus sludge formed in the electrothermal production of phosphorus by contacting the sludge with a hydrophobic surface with sufficient force to cause the droplets of phosphorus in the sludge to coalesce and accumulate on the surface, from which it can become detached in the form of large phosphorus drops.  One such recovery pro-cess involves contacting the sludge, under hydrostatic or other pressure, with a porous membrane formed of a hydrophobic material, through which passes coalesced phosphorus from the sludge, the water and the bulk of the impurities of the sludge being restrained against passage.  Other coalescing procedures in-volve shearing the sludge between sliding hydrophobic surfaces and passing the sludge between hydrophobic surfaces in rolling contact.  Typical hydrophobic materials are polyethylene, poly-propylene, and rubber.

Abstract: ABSTRACT OF THE DISCLOSURE        A non-surgical method of contraception is described which provides for the insertion of an expansible plug through the female reproductive tract into the oviduct.  When so positioned, the plug is expanded into sealing contact with the oviduct wall.  In turn, the plug can be subsequently collapsed and withdrawn when the contraceptive effect is no longer desired.      For carrying out the method, a positioning device is releasably connected to the plug to facilitate its insertion and positioning and cooperative means, electrical or mechanical, in the plug and positioning device enable control of plug expansion and/or collapse from the exterior of the female body by the attending physician.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved rechargeable lead-hydrogen electro-chemical cell is provided which comprises a cell stack secured to a retainer and disposed within a pressure ves-sel containing hydrogen gas.  The stack includes a positive electrode comprising lead oxide, a pair of gas-porous negative electrodes containing a catalyst, a pair of separators and a pair of gas screens.  The stack components are saturated with sulfuric acid electrolyte.  Each of the negative electrodes has a separator disposed on one side thereof and a gas screen disposed on the opposite side thereof.  The pressure vessel contains a gas inlet, and electrical leads connect to, respectively, the positive and negative electrodes and exit the pressure vessel.  In the charged form, the cell reactants exist as lead oxide and hydrogen gas.  When the cell is discharged, the lead oxide is reduced to lead sulfate and the hydrogen gas is oxidized at a catalytic surface to hydrogen ion.  The cell has a lower cost with fewer technical problems, has a higher specific energy density and has a superior performance, relative to conventional metal hydrogen cells.

Abstract: METHOD AND APPARATUS FOR THE REMOVAL OF OXYGEN FROM WATER                Abstract of the Disclosure Water intended for injection into an oil reservoir is freed from oxygen by gravitating the water through a vacuum tower.  Gases liberated from the water by the vacuum process are drawn off at the bottom of the respective stages of the tower.  Liberated nitrogen at the top of each stage will then flow down through the tower in cocurrent flow with the water and thus act as an internal stripping gas reducing the partial pressure of oxygen in the gaseous phase.  According to a pre-ferred embodiment of the invention gases and vapours drawn off from the bottom of each vacuum stage after the first stage are pressurized to the pressure of the preceeding stage and reinjected into that stage.

Abstract: DIFFERENTIALLY NONLINEAR CONVOLUTIONAL CHANNEL CODING       WITH EXPANDED SET OF SIGNALLING ALPHABETS            ABSTRACT         A technique for converting a sequence of binary digits into a sequence of signalling alphabets of a modulated carrier signal for data transmission.  By differentially encoding incoming data, non-linearly encoding the differentially encoded output in a state-dependent sequential manner and mapping the non-linearly encoded output into an expanded set of signalling alphabets having 90, 180 and 270 degree phase ambiguities, enlarged minimum Euclidean distance between possible sequences of signalling alphabets is achieved while the effect of the phase ambiguities of the expanded set of signalling alphabets can be removed in the receiver.  This results in a reduced error probability when maximum likelihood decoding and differential decoding are applied in the receiver.
