Abstract: ABSTRACT      A corrugated paperboard, manufactured with a layer of plastic film approximately 1-3 mil thickness, is laminated to the single face liner of single face board in the double-backer.  The board has good moisture vapor transmission (MVT) properties for packaging food and chemical products.  The film is supplied in roll form and reeved over a dewrinkling roll device to smooth it, then fed onto the single face liner as the single face corrugated is fed into the nip of the double-backer.  The lamination of the film is made by the residual heat from the paper and pressure of the double-backer belt in the drying section of the corrugator without adding adhesives or other compounds.  The film is a thermoplastic co-extruded polymeric film, e.g. high density polyethylene (HDPE), polypropylene, PET, having a heat seal layer thereon of a copolymer of olefin with Alpha-Beta monoethylenically unsaturated monomer, e.g., ethylene acrylic acid (EAA).  The film surface of the manufactured board may be optionally treated with Corona discharge or high velocity flame treatment to oxidize the surface to enhance adhesive bonding in later prepared cartons made from the board.  The process is applicable to single wall or multiwall corrugated paperboard in making a vapor barrier product having good MVTR.

Title: Control technique for an rf communication system

Granted: 1992-08-18
Abstract: CONTROL TECHNIQUE FOR AN RF COMMUNICATION SYSTEM ABSTRACT An interference detecting circuit is used in a cellular radiotelephone communication system which employs angular modulated frequencies in order to determine when to change the communication process so as to maintain the integrity of the communication path. For example, when the circuit detects an excessive amount of multipath or co-channel interference on a channel serving anactive call, the system attempts to handoff the call to another channel. Also, when the circuit detects an excessive amount of multipath or co-channel interference on a channel serving an active call, the system may decrease the effective data bit rate. The circuit includes a logarithmic envelope detector 150 for receiving a channel's angular modulated signal and for providing a log envelope output signal, a high pass filter 152 for removing a particular range of undesired frequencies from the log envelope output signal, and a level detector 154 for indicating the level of filtered output signal. The output of the level detector represents the amount of interference on the angular modulated frequency signal. A microcomputer analyzes the amount of interference to determine when such communication process changes are desired or to determine if a handoff is required.

Abstract: Abstract In three dimensional image reproduction data on the shape and true texture of a surface of an object is generated by observing the surface in a direction Z to measure X, Y, Z and MR coordinates of a number of distributed points on the surface, X, Y and Z being mutually perpendicular directions, and MR being the measured reflectance of each point.  To compensate for the fact that the values for MR do not truly reflect the inherent reflectance IR of each surface point, the MR coordinates are modified to generate corresponding IR coordinates by dividing each MR coordinate by cos a, where a is the angle of slope of the point relative to the direction Z.  The angle a can be determined for each point from the rate of change of the X and Y coordinates relative to the Z coordinate at such point.  The resulting X, Y and Z and IR coordinates can be displayed in a graphic work station to provide a two or three dimensional image viewable in an arbitrarily chosen direction, or the X, Y and Z coordinates can be used to form a shape replica of the object to which an image of the surface is applied using the IR data.  In an alternative, the IR data can be further modified by being intensity biassed in favour of those points where a is greatest to compensate for intensity lost in a projection printing process used in applying the image to the shape replica.

Abstract: Coke-contaminated catalyst particles are regenerated in a manner that achieves better utilization of oxygen and minimizes surface area loss of the catalyst by confining particles in the combustion section of a regeneration zone to a vertically elongated and tapered bed configuration.  When catalyst particles move through such a regeneration zone in continuous or semi-continuous flow and simultaneously an oxygen-containing gas is passed through the particle bed in a transverse direction, combustion of the coke deposits takes place along a burn front that extends diagonally through the catalyst bed from the inlet surface of the bed to the outlet surface of the bed.  Because the catalyst bed is tapered to reduce the volume of catalyst particles behind the burn wave, gas flow through the upper portion of the bed is increased and exposure of unregenerated catalyst to detrimental high temperature flue gas flowing across the bed from the burn front is minimized.

Abstract: ABSTRACT          A lightweight, pre-cast, reinforced, module used to build a structurally engineered retaining wall system. Each module has a panel with a front and rear surface with at least one horizontal reinforcing rod.  In the preferred embodiment, a portion of each rod horizontal transverses an integrally attached flange located at each opposite end of the panel.  On the outside surface of each flange, there is a recess across which a portion of each reinforcing rod is exposed to be subsequently surrounded by concrete of a poured-in-place reinforced column.  A horizontal row of adjacent modules is positioned on a constructed, reinforced footing.  The front surface of each module is exposed and each flange is positioned opposite to a flange located on an adjacent module with a column space created between opposite flanges.  Alignment elements are attached to the upper surface of each flange and successive horizontal rows of modules are then positioned above until the desired height is achieved.  Vertical column forms are attached to the distal and proximal edges of opposite flanges and concrete is poured down into the column space and surrounds all the exposed surfaces.  After the concrete has cured, the column forms are removed and the retaining wall structure is completed.

Abstract: A pump for medium consistency suspensions (e.g. 6-15%), such as paper pulp, simultaneously pumps and degasses the suspension. A common shaft (14) mounts a fluidizing impeller (16) and a vacuum pump impeller (24), and a common wall (29) with gas exhaust passageways (31, 34) is disposed between the fluidizing pump housing and vacuum pump housing (26). Gas separated from the suspension flows through the gas passageways (31, 34) in the common wall, through the vacuum pump, past the vacuum impeller, and is expelled out the opposite side (36, 37) of the vacuum pump from the gas inlet passageways. A pressure responsive valve (50) provides make-up air to the vacuum pump if the vacuum pulled is too strong, to prevent suspension from being pulled through the vacuum pump. A liquid inlet (40) supplies liquid in the vacuum pump to define a liquid ring (42), the inner periphery of the ring defined by the expelled gas outlet (36).
