Granted: 1982-03-16
Abstract: ABSTRACT OF THE DISCLOSURE           A surgically implantable mammary prosthesis comprises a sac containing a filler material.  The filler material is present in an amount sufficient to give the sac a relatively low profile shape and a pliant, responsive nature.  The prosthesis includes a restraining means for resisting the tendency of tissue to form the prosthesis into a sphere.  The restraining means functions reactive to tissue pressure and does not substantially reduce the pliant, responsive nature of the prosthesis.

Abstract: AIR CLEANER WITH REPLACEABLE FILTER ELEMENT     ABSTRACT OF THE DISCLOSURE      An improved filter element assembly for use in an air cleaner on an internal combustion engine comprises a perforated liner.  A replaceable filter element comprising a pleated filter medium is releasably coupled to the liner.  A safety sleeve assembly is interposed between the filter medium and the liner.  An outer liner surrounds the filter medium and exerts a radially inward force thereon to bias the pleats into engagement with the liner.  The filter element assembly can be reconditioned when the filter medium becomes used with a replacement kit which includes a new filter element, safety sleeve assembly, and outer liner.  The used filter element assembly is disassembled and the worn components thereof replaced with the new components of the kit.  The filter medium is expandable from a collapsed cylindrical form in which the filter element is shipped to an expanded conical form for use during filtering operations.

Abstract: Abstract of Disclosure A length of microstrip line 3 turns through successive right-angle corners to form a rectangular pattern comprising successive quartets a,b,c,d, of such corners.  Each right-angle corner radiates with a polarisation which is predominantly diagonal,  and the strip lengths 8,9 between the corners of each quartet are made such, in relation to the operating wavelength in the strip, that the radiation from each quartet sums to produce a desired polarisation direction, eg vertical, horizontal, or circular of either hand.  Some forms of the invention can be used in a resonant as well as a travelling-wave mode, the latter giving a main lobe whose direction sweeps with frequency.

Abstract: ABSTRACT      A fluid seal (10) for sealing against leakage be-tween relatively moving machine elements (12, 14) is capable of establishing a lubricant film between ad-jacent sliding sealing surfaces (24, 26) of the elements (12, 14) without affecting sealing between the surfaces and while establishing pressure balancing of the seal so that the pressure between the sealing surfaces is substantially less than the sealed pressure, includes as its essential elements an elastomer seal member (16) having a sealing surface (26) in sliding contact with a rigid opposed sealing surface (24).  Shaped rigid members (18) enable formation and continued generation of the lubricant film and pressure balancing of the seal by controlling the deformation of the elastomer surface (26) when the latter is subjected to the sealed pressure and sliding friction between the sealing surfaces (24, 26).          The seal can be formed both as a radial type seal with annular sealing surfaces (24, 26) and as an axial type seal with flat sealing surfaces.

Abstract: ABSTRACT           A bottom discharge hopper rail car has a hopper body mounted on a chassis which is itself supported on flanged wheels.  The body has a pair of downwardly converging, laterally spaced side walls with longitudinally extending lower edges which border a discharge opening.  The spacing between the lower edges of the sidewalls is greater than the lateral distance between the wheels as wider openings can facilitate discharge.  In practice, the wheels have outer flange surfaces adjacent to rail-engaging surfaces for resting on the rails, and the spacing between the lower edges of the side walls is preferably greater than the distance between these outer flange surfaces.  The side walls are asymmetrical with respect to a longitudinal vertical plane passing centrally between the wheels as this can inhibit bridging during discharge.  A door is pivotally mounted on the body and displaceable between a position in which it closes said opening and a position in which it is spaced from said opening to permit discharge of the contents of said body.

Abstract: OSCILLATOR SYSTEM FOR FISHING REEL                         ABSTRACT      This invention comprehends an improved means for providing a reciprocating motion for the spool of the spinning style fishing reel.  In the normal rewind mode of operation, the spool oscillates back and forth relative to the line winding means.          This has been done by achieving a reciprocating motion derived from a pin that is mounted on a rotating gear.  In the invention, the spool is oscillated by reciprocating motion of a yoke connected to a shaft mounting the spool and which coacts with a cam rotatable by the crank handle which also rotates the line retrieval structure.  The use of a cam enables design variations in the oscillations of the spool with improved winding of line thereon.

In particular, pyromellitic dianhydride is esterified in an ester such as ethyl acetate or butyl acetate to the diester/diacid by reac-tion with 2-(n-perfluoroalkyl)ethanols having six to twelve carbon atoms in the perfluoroalkyl groups, and the reaction mixture containing the dissolved diester/diacid is admixed with an oxirane compound of the group ethylene oxide, epichlorohydrin and glycidol whereby the carboxyl groups are esterified in the solvent by reaction with oxirane groups.  The product is recovered by evaporating off the solvent and unreacted oxirane compound.  The product imparts oil and/or water repellency to textiles.

Inventor: MAYER FRANZ
IPC: F26B1/00
Filed: 1980-11-28
Granted: 1983-08-16
Abstract: Abstract: Organic solid materials such as brown coals are dried by pre-ferably continously passing the pre-heated organic solid ma-terials through at least one drying stage and by subjecting the organic solid materials within this drying stage to the action of saturated steam under super atmospheric pressure and at elevated temperature. Steam is used for pre-heating the solid materials and the condensate formed is discharged prior to introducing the solid materials into the drying stage ope-rated with saturated steam. Saturated steam and preferably the steam obtained during the drying process is used for pre-heating purposes. Pre-heating itself can be effected under atmospheric pressure thereby pressure-releasing the steam obtained in the drying stage. Pre-heating is effected within a bunker (1) being connected via a pressure lock (6) with an autoclave (7). Steam is supplied via a conduit (2) to the solid materials to be pre-heated.The condensed water is discharged from the bunker (1) via a conduit (3). Additional conduits (5) can be connected to the bunker (1) for discharging the condensate from different cross-sectional planes.
