Abstract: Abstract of the Disclosure A core enveloper, for applying a web of paper, plastic or the like, to a new core, for example, on an automatic web winder, is adapted to provide for web sever-ing and core wrapping in either of two directions of wrap.  The enveloper arms including the enveloper roll, the rider roll, the cut-off knife and web transfer brush are mounted on a subframe comprising a beam which, in turn, is rotatably mounted on a support frame and is thus movable, by a drive motor, to present the core in either an "over" or an "under" position with respect to the enveloper.  The axis of rotation of the beam intersects a centerline through the core so that the geometry of the enveloper, with respect to the core, remains unchanged in either of the operating positions of the enveloper.

Abstract: Abstract of the Disclosure An adjustable over-the-top agitator for a liquid manure tank.  To periodically break up the crust on liquid manure stored in an open top tank, the liquid manure is withdrawn from the bottom of the tank and is discharged through a nozzle on the end of an external delivery pipe into contact with the crust.  The upper end of the delivery pipe is connected by a swivel coupl-ing to a vertical end of a connecting pipe, while the opposite horizontal end of the connecting pipe is connected by a second swivel coupling to the discharge nozzle. By rotating the connecting pipe about the axis of the delivery pipe, the nozzle can be moved in a horizontal path, while swiveling the discharge nozzle about the horizontal end of the connecting pipe moves the nozzle in a vertical arc.   A torsion spring is associated with the second swivel coupling to bias the discharge nozzle to a horizontal position.  Through use of the horizontal and vertical adjustments, the nozzle can be directed to all locations in the tank to more effec-tively break up the crust on the top of the liquid manure mass.

Abstract: PARTICLE CLASSIFIER ABSTRACT A particle classifier includes a generally cylindrical, air and fine particle permeable cage having a closed top and open bottom mounted to a central drive shaft. A casing surrounds the cage and defines a volute air passage about the cage with an air separation zone between the volute and the cage. A generally tangential air inlet is provided in the casing volute and a material inlet is pro-vided in the upper end of the casing. A stationary chamber is positioned below the cage for the air and fine material which enter the cage. From the chamber, the air and fine material is directed to cyclone separators in which the air is separated from the particles. A hopper is positioned below the chamber for collecting coarser material which fails to enter the cage. The size of the volute can be adjusted by vertical partition within the casing. The partition allows flexibility in setting the air velocity. Means are provided for stream-lining the air flow from the air inlet to the cage and retaining particles in the separation zone. In one case, louvers are provided for these two pur-poses, and in another case a screen is provided between the volute and particle separation zone.

Abstract: FOAM FILLED INSERT FOR HORIZONTAL CRYOSTAT             PENETRATIONS                   Abstract of the Disclosure An insert for a horizontal cryostat penetration includes a plurality of foam particles or spheres between which are disposed disks of high thermal conductivity.  The spheres or particles are disposed in an annular volume defined by two concentric, thin-wall, low thermal conductivity conduits.  This foam filled insert provides thermal insulation and significantly reduces the formation of coolant vapor convection currents in the penetration which would otherwise significantly increase the rate of coolant evaporation from the cryostat.  The insert is constructed so that the foam particles are  ejected from the penetration upon the buildup of excessive internal pressure.  The insert has also preferably one or more string-like lengths of sealing material disposed in a helical pattern about the outer one of the concentric conduits.  Accordingly, when this insert is placed within a third conduit, a helical coolant vapor path is formed for insert cooling and exterior ventilation.

Abstract: ABSTRACT        A drill string safety valve operator provides a rotatable  tubular  body  having  a  longitudinal  through bore for conveying fluids.   A valve member is movably disposed  within  the  body  for  valving  the  fluid  flow through  the bore.   A crank arm extends  from and is coupled to the valve member at the valve stem for moving the  valve member  between  open  flow  and  closed  flow positions responsive to rotation of the crank arm.   A bearing is carried at the outboard end of the crank arm for transmitting load to the crank arm.  An annular ring is supported about the tubular housing and provides a surface  that  can  engage  the  bearing.     Hydraulic cylinders power  the annular  ring so that  the annular ring engages the bearing.  Downward movement of the ring causes a corresponding downward movement of the bearing and  a corresponding  rotation  of  the  crank arm.   The apparatus thus allows quick remote closure of the valve during a blowout condition of the drill pipe bore.

Abstract: ABSTRACT OF THE DISCLOSURE    Carbonating apparatus includes a reservoir to be filled with fresh water through an outlet.   Rotation of a control opens a valve, so that water passes from the reservoir into a pressure vessel.   The control is then depressed to cause pressurised gas to be introduced into the water in the vessel, via a nozzle, from a gas cylinder, so as to carbonate the water.   A slidably-operable control is then moved by an initial amount to cause a venting valve to open, thereby venting excess gas in the vessel to atmosphere.   Further sliding movement Or the slidably-operable control depresses a lever connected to an outlet valve, which permits dispensing of the carbonated water from the vessel, via a spout.

Abstract: PROCESS FOR DETECTION OF SELECTED MOTILE ORAGNISMS                  Abstract of the Disclosure Methods and associated devices for detecting the presence of a particular motile organism within a sample are disclosed.  The sample may be derived from dry milk, raw meat, poultry or a clinical specimen. A preferred method includes inoculating a selective enrichment medium containing a chemo-tactic attractant with the sample and contacting the selective enrichment medium with a nonselective motility medium contain-ing a chemotactic attractant in a concentration less than the attractant concentration in the selective enrichment medium. Upon incubation, the motile organism metabolizes the chemo-tactic attractant, allowing the organism to move into the motility medium where it interacts with antibodies specific for the organism, thereby causing the formation of a persistent immobilization band.  The methods are particularly useful in detecting Salmonella.
