Abstract: This invention presents novel separation and assay procedures which allows both the indicator and the capture reagents to be in solution to avoid problems of slowedimmunoreaction kinetics. The separation procedure involves an analyte-specific soluble capture reagent, that is conjugated to a charged substance, and an insoluble solid phase material that is oppositely charged. A fluid sample suspected of containing the analyte is mixed with the capture reagent in solution to form a charged capture reagent/analyte complex. When binding is complete, the solution is contacted to the oppositely charged solid phase material to attract, attach, and separate the capture reagent/analyte complex from the fluid sample. With the appropriate indicator reagent, i.e., a second analyte-specific binding substance which is conjugated to a label capable of producing adetectable signal, both sandwich and competitive assays can be performed. The assay reaction complex can be separated from the solution by contact with the oppositely charged solid phase material, and the presence or amount of analyte is monitored by detecting the label of the indicator reagent.

Abstract: IMPROVED METHOD AND APPARATUS FOR WITHDRAWAL OF    SMALL CATALYST PARTICLES IN FCC SYSTEMS                              ABSTRACT           Disclosed is a method of and apparatus for reducing the level of extremely small catalyst particles ("fines") in an FCC system by temporarily retaining particles separated from the secondary cyclone separator in a reactor vessel or catalyst regenerator,  These particles can be intermittently withdrawn from the temporary retaining area in order to achieve particle flow at a low volume rate, which takes them out of the active catalyst inventory within the reactor/regenerator system.  The intermittent withdrawing of catalyst "fines" reduces the particulate contamination both in flue gas exhausted to the atmosphere from the catalyst regenerator and in the main column bottom (MCB) products from the fractionation stage.  Preferred embodiments include intermittent withdrawal of "fines" from either the regenerator or the reactor vessels and the secondary cyclones contained in each of these vessels.

Abstract: ABSTRACT OF THE DISCLOSURE             JOINING POLYOLEFINIC MEMBERS BY FUSION            Members especially hollow members 10, 12 such as pipes and pipe fittings, one member 12 being of, for example, cross-linked polyethylene and the other member 10 being of, for example, medium density polyethylene, are joined by fusion using a butt fusion machine.  End surfaces of the members are pressed at higher pressure against a hot plate 18 to upset only the medium density material to form beads 20, 22.  No cross-linked material is upset to form beads.  The pressure is reduced during a soak stage, then the plate is removed and the surfaces are mutually engaged at the higher pressure.  The beads formed are adjacent the interface between the members and both beads are offset towards the medium density material, member 10.  Careful alignment will avoid faults caused when the beads do not cover exposed parts of end surfaces.  Other materials include polypropylene, copolymer or homopolymer types.  Natural gas distribution systems can be fabricated using the invention.

Granted: 1994-08-09
Abstract: Abstract of the Disclosure An  improved  skimmer  is provided  for  recovering hydrocarbons floating on the surface of a body of water.  A floating  hull  defines  first  and  second tunnels,  and  a holding  tank  for  housing the collected hydrocarbons.   A power driven propeller in the first tunnel draws subsurface water from an inlet port through the first tunnel and out a discharge port.   The inlet port of the second tunnel is positioned  above  the  first  tunnel  to  receive  floating hydrocarbons  and  water.   The second  tunnel  has  a water outlet  in fluid communication with the first tunnel.   A skimming gate passes hydrocarbons floating on the surface of water in the second tunnel to the holding tank, and thereby separates hydrocarbons from the water.   According to the method   of   the   present   invention,   hydrocarbons   are efficiently recovered from the surface of the water while a high  percentage  of  water  initially  collected  with  the hydrocarbons  to  assist  in  the  recovery  operation  is discharged back to the body of water, thereby reducing the quantity of hydrocarbons which must be transported from the holding tank on the hull.

Abstract: A hollow cathode type inverted cylindrical magnetron apparatus construction comprises two separate units each having a rectangular C shape cross section. The two C shaped units are positioned together to form a hollow rectangular parallelpiped like cavity and articles to be sputtered are passed through this cavity. Bolted construction of simple elements having simple geometry are used to produce a very inexpensive structure which is easily serviceable. This magnetron construction uses permanent magnets all having the same north south pole orientation located behind the target material and surrounded on three sides by magnetic permeable material to confine the magnetic flux path. Hence the lines of force tend to be parallel to the substrate surface of the article very near to that surface and heating of the substrate is minimized. Cooling is provided by coolant carrying tubes interspersed between the magnets and the target material.

Abstract: PACKET DATA COMMUNICATION SYSTEM     ABSTRACT OF THE DISCLOSURE: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiatecommunication to the remote units, but instead send data to the remote units only as part of the exchange.

The first sealing body is located in the pipe inwardly of the testing location and is adapted to be pressed from within against the surface of the pipe, and the second sealing body can be pressed against the periphery of the sleeve. This renders it possible to test, already within the manufacturing plant, even short pieces of piping for impermeability to leaks.
