Title: Reinforced carton handle
Inventor: DAWSON RAYMOND L
IPC: B65D5/468
Filed: 1992-10-13
Abstract: An enclosed carrier (10) having spaced handle openings (22, 24) in the top panel (14). The top panel is formed from two overlapping flaps (18, 20), each of which has a folded-over edge portion adhered to itself. The folded-over edge portions overlie each other to form the strap portion (26) of the handle extending between the handle openings, with the folds (60, 64) of the edge portions being aligned with the inner edges of the handle openings. In one embodiment the handle strap comprises a four-ply lay-er and in another embodiment it comprises a three-ply layer. The folded-over edge portions of the top flaps may be weakened at their intersection with the fold lines of end panel flaps to enable the end panel flaps to be readily folded into place.

IPC: A23N12/08
Filed: 1993-06-28
Abstract: ABSTRACT          The system foresees the heat and smokes production into combustion chamber  (1),  by means of burner  (2),  and through a collector (3) their reaching into a heat exchanger (4) with distinct flows where they make over by induction their heat to an air flow sucked from outside by an air intake (5). The flow coming from said air intake (5) so heated is let by pipe (6) into chamber (7) centrally including the combustion chamber (1). In this way said forced flow is overheated by  contact  with  the  walls  of  the combustion chamber  (1)  to the needed temperature and by means of pipe (8) is coming in roasting chamber  (9)  where  it runs  over goods  in  movement  into roasting unit  (10).  Said heat  air flow crosses the goods so to heat the same to the needed temperature and then it is discharged through pipe  (11)  with in suspension the roasting smokes and it is then sucked by  and  intake  group  (12)  forming  the  forced circulation.          Said gaseous flow comes finally to a cyclone separator (13) having the function to take from the air flow the bigger dimension particles.          The  flow  so  cleaning  through  a post-combustion unit  (14),  able to overheat the suspended residues give out by the working goods to a higher temperature to the ignition temperature,  is then turn out  into  the  outward  environment  to  a variable  temperature from 400° to 700°.

Title: Method for making soft tissue
Inventor: KAMPS RICHARD J
IPC: D21F11/00
Filed: 1993-08-04
Abstract: Paper sheets, such as creped tissue sheets used for converting into tissue products such as facial tissue and bath tissue, can be softened with by passing the sheets through one or more fixed-gap noncompactive straining nips formed between two engraved rolls having partially-engaged small straining elements of a shape which strains the sheet in all directions. The straining treatment substantially reduces the rigidity of the tissue sheet by increasing the internal bulk without substantially reducing the tensile strength. The method provides a means for making a throughdried-like tissue sheet from a wet-pressed tissue sheet.

Title: Premix single stage low nox burner
Inventor: NUTCHER PETER B
IPC: F23D14/82
Filed: 1993-10-15
Abstract: ABSTRACT OF THE DISCLOSURE           A premix burner has a mixing plenum,  a mesh flametrap and a ceramic honeycomb arranged in series.  The mixing plenum has inner and outer chambers, with a mixing nozzle  for  introducing  a  gaseous  fuel  concentrically located in the inner chamber.  The burner is operated with either  high  excess  air  or  flue  gas  recirculation to produce a low temperature flame at a flame face defined by the honeycomb.   The thorough premixing of air and fuel ensures a flame with homogeneous air-to-fuel ratios across the flame face, producing low NOx levels.  The honeycomb and flametrap also function as flame arrestors to prevent burner  flashback.     A  method  for  attaining  a  low temperature,  low NOx  flame using  excess air,  with  or without flue gas recirculation, is also disclosed.

Title: Noise reduction of electrical signals
Inventor: HANSON THOMAS A
IPC: G01M11/00
Filed: 1994-11-10
Abstract: Methods for determining optical properties of an optical waveguide fiber using an optical time domain reflectometer (OTDR) are provided.  The methods involve the removal of noise from an OTDR trace  (signal)  by fitting the noise component of  the  signal and then subtracting the fitted noise from the original signal to produce a noise-reduced signal.  Optical properties are more readily determined from the noise-reduced signal than from the original signal.  In particular, the noise-reduced signal can be used to determine axial optical properties of long fibers, e.g., fibers having a length of 50 kilometers or more.
