Title: Composites of paper and plastic film, corrugated paperboard incorporating said composites and methods of making
Inventor: OLVEY MICHAEL W
IPC: B32B3/28
Filed: 1989-12-11
Abstract: Composites of paper and bioriented plastic film, preferably polyester, are made by passing into and through the nip of a pair of nip rolls a web of paperboard and a web of plastic film, with a layer of molten polymer impregnating and bonding agent extruded into the nip between the webs on the entry side of the nip. The process involves relatively controlling one or more of the speed of the webs, the temperature of the molten polymer, the pressure or spacing of the rolls at the nip, and the rate of extrusion, relative to the porosity and surface characteristics of the paper web such that a substantial portion of the molten polymer impregnates partially into and becomes part of the paper web and a substantial portion lies outwardly of the surface of the paper web and solidifies to form a new surface to which the film is bonded and an which it is supported clear of the paper surface. The product as collected from the nip rolls is a composite comprising paper partially impregnated with solidified polymer, a contiguous layer of solidified polymer having the new surface outwardly of the paper surface, and the plastic film bonded to the new surface. The film may be reverse printed with high quality graphics which are retained in the composite. Various treatments of the film and the paper enhance the characteristics of the composite. The composite is highly resistant to separation or checking when scored and formed into container blanks, and can be combined with a single faced corrugated board in the "double-backer" part of a conventional corrugating machine as the double face liner without adversely affecting the film, its graphics, or the impregnating and bonding polymer. Principal uses are in packaging, point-of-purchase displays, wall panels, and the like.

Abstract: APERTURE SYNTHESIZED RADIOMETER                USING DIGITAL BEAMFORMING TECHNIQUES                               ABSTRACT A digital aperture synthesized radiometer (10) for synthesizing and imaging an scene. A plurality of antenna arrays (12) receive radiation emitted or reflected from an scene, and an analog to digital converter (16) converts received radiation into digitized signals. A digital beamformer (18) synthesizes the digitized signals to pro-vide an image corresponding to the scene. The digital beamformer (18) comprises individual digital beamformers which generate a set of fanbeam signals (13) for each array. The beamformers (18) provide for cross track imaging of the scene. A digital interferometer (20) correlates corresponding pairs of fanbeam signals (13) from the two sets of fanbeam signals to produce a chirp signal for each pair. A matched filter (22) processes the chirp signals to transform each chirp signal into a corresponding image point of the scene. This provides for along track imaging of the scene. The beamformers (18) include an amplitude weighting and data turning circuit (32) to re-duce fanbeam signal sidelobe levels and eliminate alternate mainlobes from the digi-tized radiation signals to reduce mainlobe widening. A fast Fourier transform circuit (34) in the beamformers (18) generally comprises a decimation-in-time algorithm im-plemented by means of a plurality of parallel and cascaded butterfly computation cir-cuits. Image processing methods for achieving digital radiometry are also disclosed.

Title: Device and method for removing gaseous impurities from a sealed vacuum
Inventor: LABATON ISAAC J
IPC: F24S10/40
Filed: 1990-05-04
Abstract: ABSTRACT OF THE DISCLOSURE    A container is disposed within a vacuum insulation jacket which surrounds a vessel or pipe which contains or through which flows a hydrogen containing medium.  The con-tainer holds oxygen under pressure or holds a material which liberates oxygen when exposed to heat and/or reacts with water to liberate oxygen.  The container is sealed by means of a membrane of palladium or palladium alloy.  A water absorbing material is disposed inside the container.  The palladium membrane is thus exposed on its first side facing the interior of the container to a region of relatively high oxygen pressure produced by the oxygen inside the container and low hydrogen partial pressure inside the container, and is exposed on its other side to the vacuum (low oxygen pres-sure, and higher hydrogen partial pressure as a result of the outgassing or permeation of hydrogen from the medium in contact with the vacuum chamber walls).  The palladium acts as a catalyst for the combination of hydrogen and oxygen to form water when hydrogen flows from the vacuum jacket into the container following the hydrogen pressure gradient. The water thus formed is absorbed inside the container using a suitable water absorber, such as a molecular sieve.  The method of using the device includes placing it within a vac-uum chamber or between two concentrically arranged pipes constituting a vacuum chamber so that the palladium or pal-ladium alloy membrane is in thermal communication with a high temperature surface, such as the surface of the wall of the pipe containing steam or a heat transfer fluid.

Inventor: WOODWARD DONALD W
IPC: F25J3/04
Filed: 1990-05-14
Abstract: ABSTRACT   The present invention is an improvement to a two distillation column cryogenic air separation process which produces nitrogen-rich and oxygen-rich products.  The improvement to the process is condensing at least a portion of the nitrogen overhead from the high pressure column in a reboiler/condenser against a crude liquid oxygen stream and in an intermediate reboiler/condenser located in the low pressure column against internal low pressure column streams.  The condensed nitrogen overhead is fed either to the low pressure or high pressure columns as reflux.  The vaporized portion of the crude liquid oxygen stream is work expanded to provide some or all of the refrigeration required for the process.

Abstract: A water-continuous composition, that contains, calculated on the water:  (i)  more than 200 ppm amino acid residues; and (ii) more than the critical concentration of one or more gelling polysaccharides capable of forming a reversible gel, is cooled from above the gel setting temperature of the water-continuous composition to below the gel setting temperature and is subjected to shear conditions such that the water-continuous composition is converted into small gelled aqueous beads.  A fat-continuous dispersion is formed, while maintaining the temperature at below the gel melting temperature, in which the dispersed gelled aqueous phase has a droplet diameter distribution value sigma which exceeds 0.9 micrometers (microns).  The process allows the simple preparation of water-in-oil dispersions of very low fat content.

Patent CA-2021638-A1 (CA)
Inventor: DUBE GHYSLAIN
IPC: C22B1/00
Filed: 1990-07-20
Abstract: PCT No. PCT/CA91/00252 Sec. 371 Date Jan. 4, 1993 Sec. 102(e) Date Jan. 4, 1993 PCT Filed Jul. 18, 1991 PCT Pub. No. WO92/01825 PCT Pub. Date Feb. 6, 1992.The invention relates to a process of decontaminating metal (especially aluminum or aluminum alloy) scrap contaminated with organic material. The problem with such methods is that undue oxidation of the metal may take place as the decontamination proceeds, leading to reduced recovery rates. The process involves heating the scrap in a fluidized bed of solid particles fluidized by a fluidizing gas to a decontaminating temperature high enough to consume the organic material but below the melting point of the metal. The heating step is carried out in the presence of a protective material which protects the aluminum or aluminum alloy against substantial oxidation while the scrap is held in the bed at the decontaminating temperature. Preferred protective materials include organic and inorganic fluorine-containing compounds, particularly AIF3. The process is particularly effective for the treatment of aluminum alloys containing magnesium, which are especially susceptible to oxidation. Scrap decontaminated in this way can be subjected to conventional metal recovery processes, e.g. metal melting, and provide high recovery rates of the metal. The process of the invention can also be used for protecting metal (particularly aluminum and alloys thereof) against excessive oxidation during heat treatments other than decontamination. The invention also relates to the treatment of briquettes of compacted scrap without the need for protection from oxidation and without the need for prior shredding or grinding.
