Abstract: ABSTRACT An appliance for applying a dynamic pressure wave against an extremity is disclosed.  The appliance includes an inflatable cylindrical tapered cone chamber which is adaptable for surrounding the extremity.  The cone chamber has a larger diameter outer end and a smaller diameter inner end and can be divided into a plurality of longitudinally extending tubular chambers. When inflated, the cone is sufficiently large and rigid to surround the extremity and prevent an exterior pressure from being applied thereto.  An inflatable sleeve chamber encloses the cone chamber.  The sleeve is formed of a bag-shaped bladder open at one end and closed at the other end.  When inflated, the sleeve chamber defines an internal space small enough to exert a compressive force on the exterior of the cone and the extremity enclosed therein.  When the cone chamber is inflated and then deflated as the sleeve chamber is inflated, the appliance will cause a pressure to be applied to a human or animal extremity which begins at the smaller diameter end of the cone chamber and travels up the extremity in the nature of a pressure wave.

Abstract: ABSTRACT   The present invention relates to a process for the recovery of metals from the scrap from nickel-cadmium electric storage batteries or other products which in addition to cadmium also contain organic substances and metallic components made of iron, nickel or other metals. The process involves opening the batteries and emptying them of any free electrolyte, drying the scrap, removing the organic substances by pyrolysis at an initial temperature followed by condensation. The pyrolysis and distilling-off opera-tions are performed in one and the same furnace by the successive and pre-programmed raising of the temperature inside the furnace, for example in stages, in order to produce a residue inside the furnace in the form of nickel and iron scrap.      Pyrolysis takes place in a controlled atmosphere, requiring the introduction of an inert gas such as nitrogen with the addition of between 3 and 12% of oxygen, if necessary in the form of air. Pyrolysis is made to occur by raising the temperature inside the furnace from about 100°C to an initialtemperature of about 400°C or 500°C. The vaporization of the cadmium takes place at a second temperature of up to about 900°C in the presence of a reducing protective gas. The cadmium vapour is condensed and the liquid metal is cast into cadmium rods.

Abstract: A B S T R A C T            Process for the large-scale production of a vaccine against poliomyelitis and the resulting vaccine.     For each type of poliomyelitis virus used, there is multiplied a cell strain by means of culturing on microcarriers in suspension and by successive passa-ges into increasing volumes of biogenerators, the last of which holds at least 150 liters, into a suitable nu-tritive medium. At the end of the final passage, the li-quid medium is drawn off and replaced by a new liquid me-dium containing no serum. After inoculation, the virus is allowed to develop in suitable temperature, pH, and par-tial oxygen pressure conditions. The liquid suspension is withdrawn after virus culture. The suspension drawn off is filtered. The filtered suspension is concentrated at least 150 times by means of ultrafiltration. A gel filtra-tion of the concentrated suspension is carried out. The suspension obtained is subjected to ion exchange chromato-graphy. The concentrated suspension obtained is diluted with a serum free medium. The suspension thus diluted and purified is inactivated. The suspension of the respective types used are mixed and the individual dosages are pre-pared.

Abstract: Title of the Invention:         IMPROVED AIR WEFT INSERTION NOZZLE CONTROL SYSTEM          Abstract of the Disclosure: The actuation of a nozzle utilized for propelling the yarn in an air weft insertion weaving system is controlled by means of a single rotary servo valve having an arrangement of ports adapted to be brought during valve rotation into registration alternately with an air pressure source and with the atmosphere for alternately pressurizing and venting a pilot chamber for opening and closing the nozzle. Preferably, the rotary valve includes a rotary spool enclosed within a sleeve of air permeable material to provide an air bearing for the spool. The actuation of the nozzle is determined by the movement of a diaphragm valve toward and away from the opening of a nozzle supply chamber under the control of the pilot chamber pressure, and the diaphragm is deformed into two annularly separated generally U-shaped convolutions opening toward the interior of the air supply chamber of the nozzle so that the movement of the diaphragm during opening and closing follows a "rolling" or progressively flexing action as the convoluting side walls telescope outwardly and inwardly relative to one another. Preferably, two substantially similar convoluted diaphragms are disposed in axially spaced oppositely directed relation, one exposed to the nozzle supply pressure and the other to the pilot chamber pressure. Advantageously, the interior space between such dia-phragm is vented to the atmosphere to maintain a pressure-free condition therein and clearances are provided to prevent entrapment of air resisting deflection of either diaphragm.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention is directed to an advanced epoxy resin and to a coating composition comprising (I) the advanced epoxy resin, (II) a curing quantity of at least one curing agent for component (II), and (III) at least one solvent in a sufficient quantity such that the coating composition including components (I), (II) and (III) and any other desirable components has a suitable application viscosity.  This invention is characterized in that the advanced epoxy resin is prepared by reacting in the presence of a suitable catalyst (A) a composition comprising (1) at least one aliphatic diepoxide and, optionally, (2) at least one aromatic diepoxide, with (B) at least one compound having two aromatic hydroxyl groups per molecule, wherein components (A-1) and (A-2) are employed in quantities such that from 10 to 100 percent of the epoxide equivalents contained in component (A) are contributed by component (A-1), from 0 to 90 percent of such epoxide equivalents axe contributed by component (A-2) and wherein components (A) and (B) are employed in quantities such that the resultant advanced epoxy resin has an average epoxide equivalent weight of from 350 to 30,000.  The cured advanced epoxy resins of this invention have increased elongation values when cured with a curing quantity of a suitable curing agent as compared to similarly cured advanced resins prepared by reacting together only component (A-2) with component (B).  The advanced epoxy resin of this invention requires less solvent to reach a desired viscosity value as compared to the quantity of solvent to reach a like viscosity value for a resin compound from component (A-2) and component (B).     The advanced epoxy resins of this invention are useful as automotive primer surfacers, automotive stone chip resistant coatings and coil coatings where somewhat reduced physical and/or chemical properties can be accepted for an improvement in flexibility or a reduction in the amount of volatile solvent required to achieve a suitable application viscosity.

Granted: 1985-12-17
Abstract: ABSTRACT     Substantially complete cancellation of continuous wave or slowly varying continuous wave interference with no loss in the received level of the desired signals is provided for a spread spectrum system which utilized orthogonal multi-plexed noise codes which when orthogonally multiplexed, detected in a matched filter detector and linearly added, compress to a lobeless impulse.  The noise codes are comprised of binary digital noise codes which compress to a code bit width .gamma..  The CW interference is eliminated by means of a variable delay line and a linear adder.  The delay line operates to provide an interference signal from the input interference signal which is exactly 180°  out of phase with respect to the input interference signal.  By adding the delayed signal to the input signal in the linear adder, a total cancellation of the  interference signal occurs while the signal level of the noise coded communications signal remains unchanged.
