Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed are hydrophilic polyolefinic microporous materials and a method for the preparation thereof.  Such materials are prepared by impregnating a normally hydrophobic polyolefinic microporous substrate material with a solution of a nonionic alkylphenoxy poly(ethyleneoxy) ethanol surfactant having an HLB of from about 10 to 15 in a solvent system comprising from about 55 to about 65 volume percent methanol or acetone and from about 35 to about 45 volume percent water.  It has been dis-covered that polyolefinic microporous materials rendered hydrophilic by this technique not only wet rapidly, but in addi-tion may be multiply re-wetted with aqueous solutions, such as aqueous alkali solutions, with excellent retention of their hydrophilic properties.  The hydrophilic polyolefinic microporous materials of this invention find particular application as battery separators and as membranes for use in various chemical, medical and biotechnical processes.

Abstract: ABSTRACT OF THE DISCLOSURE The invention concerns a frequency modulation broadcasting trans-mitter in which the output oscillator at the transmission frequency is modulated not directly by the audiofrequency signal but through the intermediary of a phase locking loop comprising a phase comparator supplied, on the one hand, by the output signal filtered from a picture or image frequency rejection mixer. This mixer receives, on the one hand, a modulated intermediary frequency signal from a modulator and, on the other hand, the output signal of the oscillator at the transmitting frequency Fs, the reference frequency Fo1 being determined as a function of the central transmitting frequency and of the intermediary frequency Fo1 = FS - F1 .

Abstract: Abstract of the Disclosure The invention relates to a hydraulic motor, which comprises a surrounding frame casing; an internal cylinder block with radially arranged cylinders and a stationary axle of the hydraulic motor attached thereto; pistons reciprocating in the cylinders and bearing the inner surface of the frame casing, which surface is formed as a running surface guiding the movement of the pistons; a fluid distributor mounted around the axle to rotate together with the frame casing, for the distribution of the hydraulic fluid into cylinder chambers and away therefrom via openings provided in the cylinder block; and feed and exhaust channels for the hydraulic fluid.  The object of the invention is to improve such a hydraulic motor by compensating, without complicated balancing elements, the force caused by the pressurized hydraulic fluid and separa-ting the fluid distributor and the cylinder block. This has been solved according to the invention in such a manner that a ring space is formed between the fluid distributor and the axle, by means of stepped counter     surfaces of the axle and the fluid distri-butor, said ring space being formed in the feed channel for the hydraulic fluid.

Abstract: ABSTRACT OF THE DISCLOSURE          A filter cartridge for removing particles or dust from a stream of moving gas or air, including a filter medium disposed between a pleated inner wire support frame, outer longitudinal wire support stays disposed along each inner apex of the pleats of the filter medium, and end caps.  The outer wire stays are formed from inwardly bent wires which attach at each end to the inner frame and exert pressure on the filter medium to support it against inner pressure of a pulse jet cleaning device.  Preferred filter media are felt or fabric composites containing a layer of porous expanded polytetrafluoroethylene membrane.  A preferred form of lower end cap has the periphery contoured to conform to the configuration of the filter medium and inner support frame. he cartridge structure is advantageous in preventing build-up of ledges of dust on protuberances, with consequent reduction of filter efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE      Joints for optical fiber, submarine cables in which the tensile resistant element is centrally located in the cables, rather than at the exterior of the cables, and all spaces between the cable elements are filled with a substantially incompressible fluid.  In the joint, the end of the tensile resistant element of one cable is joined to the end of the tensile resistant element of the other cable by a tubular clamp which is surrounded by a plastic layer having through-cavities in which the optical fibers are received and joined.  If the optical fibers are in fluid filled tubes, the tubes are connected by further fluid-filled tubes surrounding the optical fiber connections.  The plastic layer may be surrounded by a further plastic layer, and the cable metal sheaths are interconnected by a metal tube in watertight relation to the sheaths.  The metal tube is surrounded by a plastic sheath and if desired, other layers, other than an armor which, by itself, can sustain the water pressure, may surround the plastic sheath.

Those individuals showing above normal levels of IgA RF proceeded to a severe disease state with the appearance of bone erosions while those showing above normal levels of IgM RF did not proceed to such a severe state.  Furthermore, disease activity in such individuals has been found to correlate with fluctuations in the level of IgA RF in the blood.

Abstract: A b s t r a c t A method for docking of a floating structure, e.g. a concrete offshore platform.  According to a first embodiment, a pit (3) separated from the sea by means of sand or gravel deposits (1; 4) is exca-vated, whereupon the structure (7) is erected entirely or partly in the pit (3).  The depth of the pit (3) is increased by building the upper edge of the pit upwards to an upper level, whereupon the pit is filled with water (10) in order for the structure to become floating.  The deposits (12) situated at the bottom of the pit (3) and under the structure (7) are next removed by means of suitable techniques in order to lower the bottom of the pit (3) to a lowest level, while the level (11) of the water (10) in the pit (3) is maintained.  Then the level of the water (10) is lowered to a lower level (14) corre-sponding to the level of the sea (2) on the outside and the dike (4; 8) separating the pit from the sea is removed, whereupon the structure may be floated away from the pit.  According to a modification, two pits are excavated next to each other, one being deeper than the other.  After the structure is erec-ted, the pits are filled with water and the struc-ture is floated from the shallower to the deeper pit.  Next, the water level of the pits is lowered to the level of the sea on the outside, whereupon the dike separating the pit from the sea is removed.

Abstract: DISC ASSEMBLY WITH WELDED DISCS               ABSTRACT OF THE DISCLOSURE        A disc separator includes discs welded to a hub.          Each disc has an extruded collar disposed around a central aperture through which the hub extends.  The collar provides bending rigidity to the disc and is interposed between the disc and hub to insulate the disc from thermal stresses caused by welding.  The hub has an open seam and an initial diameter less than the diameter of the central aperture of the discs.  The discs are assembled on the hub by sliding each of them to a predetermined position on the hub, expand-ing the hub, welding the collar to the hub, and relaxing the hub.  The steps are repeated until a plurality of discs are securely welded to the hub to form a disc assembly.

Abstract: "APPARATUS FOR TRANSFERRING PARTICLES         FROM ONE ZONE TO ANOTHER"                   ABSTRACT OF THE DISCLOSURE Apparatus for transferring particulate contact material by gravity flow from an upper contact zone wherein it is contacted by a first gas stream flowing radially, to a lower zone wherein it is contacted by a second gas stream flowing upwardly.  The apparatus includes a generally annular particle-containing transition zone which connects the upper and lower zones. The vertical height of the transition zone effectively prevents the second gas stream from contacting the particulate material in the upper zone.  In a preferred embodiment in the form of a catalyst regenerator, catalyst particles can be sampled for carbon level in the transition zone to determine if the carbon burn-off therefrom is sufficiently complete in an upper radial flow regenerator bed by contact with a first gas stream, having a relatively low oxyten level. The sampling can be done on stream,: even though a second----gas stream, such as relatively oxygen-rich halogenation gas, is passing up through the catalyst in the lower zone.
