IPC: B32B29/02
Filed: 1987-12-23
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE             A novel laminated paperboard is provided herein.          The laminated paperboard comprises a first layer of paperboard having a thickness in the range of 0.3 mm to  1.5 mm.   A  second  layer  of  paperboard  has  a thickness in the range of 0.3 mm to 1.5 mm, with the outer surfaces of the first and second layers being flat and smooth. A first internal layer of contoured paperboard having a thickness in the range of 0.23 mm to 0.5 mm and having grooves and ridges is disposed between, and glued to, the inner surfaces of each of the  first  and  second  layers  of  paperboard.   The grooves and ridges have a height in the range of 0.90 mm to 1.2 mm.  The first internal layer of contoured paperboard has in the range of 350 to 400 sets of grooves and ridges per linear meter of paperboard.          The curved surfaces on one side of the first internal layer of contoured paperboard is indented within the inner surface of the second layer of paperboard by at least 0.1 mm to increase the area of surface contact and  gluing  area  between  the  layers,  thereby  to increase the rigidity and strength of the laminated paperboard. Because of this structure, the laminated paperboard  has  characteristics  of  strength  and rigidity equivalent to solid laminated paperboard, but is 30% to 45% lighter in weight.

Abstract: ABSTRACT                        Seaming apparatus for joining the adjacent side edge portions of two adjacent panels to provide a continuous seam is disclosed.  The apparatus includes a support base having a main base portion and a movable base portion.  The movable base portion is pivotally connected to the main base portion for pivotal movement about an axis between a first positon and a second position.  Sets of opposed motor driven seaming rollers are mounted on the base with one roller of each set being rotatably mounted on the movable base portion and the other roller of each set rotatably mounted on the main base portion.  The rollers of each set are oppositely disposed and have peripheral surfaces arranged to engage the adjacent side edge portions of the adjacent panels.  A drive train driven by a motor and including a drive gear for each driven roller is provided for rotating the driven rollers to move the apparatus along the adjacent side edge portions. Actuating means is mounted off one side of the movable base portion for pivotally moving the movable base toward and away from the main base between the first position and the second position.  When in the first position, the axes of the rollers of each set of driven rollers will be substantially parallel.  When in the second position, these axes will form an included angle of less than 30 degrees which maintains the drive gears of each set of rollers in meshing engagement.  One seamer has four sets and the other three sets of seaming rollers.  The latter form uses a cam surface to direct one of the rollers of one set in a selected path to move the roller to a horizontal position and to clear the formed seam.

Abstract: Abstract:   The invention relates to a laminated tamper-evident structure which exhibits an irreversible colour change upon delamination.  The structure includes a laminate of at least two layers capable of generating a colour by a light interference and absorption phenomenon that requires direct and intimate contact between an adjacent two of the layers.  The strength of attachment among the layers of the laminate is such that the laminate can be uniformly and reliably peeled apart at the interface between the adjacent two layers.  An overlying flexible strip of transparent or translucent material is adhered to the laminate to facilitate the peeling operation. Upon peeling apart the laminate, the generated colour is irreversibly lost, thus providing evidence that the structure has been tampered with.  The structure can be incorporated into a variety of closable articles or products to provide evidence of opening or tampering.

Abstract: DOCUMENT MOISTENING DEVICE Abstract of the Disclosure Apparatus for applying moisture to a flexible document containing a water-activated adhesive. The apparatus includes a reservoir for storing a source of water, a mounting bracket extending from the reservoir, a pivotable hammer pivotably mounted to the bracket and extending toward the reservoir, and a moistening wick extending from the reservoir toward the pivotable hammer. The area between the moistening wick and the pivotable hammer defines a document path. The apparatus further comprises a flexible, one-way gate secured to the lower portion of the hammer for movement therewith, the gate having an end portion extending into the document path. The apparatus also includes a gate deflector secured to the gate and lower hammer portion for movement therewith. Movement of a document up the document path from the gate deflector toward the pivotable hammer causes the gate to flex out of the document path and movement of a document down the document path from the pivotable hammer toward the gate deflector causes the gate to engage the document and bend around the gate deflector to thereby cause the hammer to pivot and urge the document against the wick. Thus, moisture is applied to those portions of the document urged against the wick. The invention is especially useful in combination with a buckle chute folder.

The fan unit includes electrically driven fans mounted with their axes vertical and the cooling unit includes open ended tubes arranged side by side with their axes in a horizontal plane and transversely spaced apart to form passages therebetween.  One open end of each tube is adjacent the front of the rack and is open to the atmosphere through a grill;  the other open end of each tube is spaced inwardly from the rear of the rack and opens into an otherwise fluid-tight compartment in which are housed electrically driven fans and associated deflectors.  Air within the enclosure heated by heat emitted by the electrical and/or electronic apparatus is caused to flow upwardly or downwardly by the fans of the fan unit through the passages between the transversely spaced tubes of the cooling unit and is cooled by air initially at ambient temperature which is drawn by the fans of the cooling unit from outside the enclosure through tubes of the cooling unit into the compartment and is deflected by the deflectors through other tubes of the cooling unit and out of the unit.

Inventor: TONG HUA-SOU
IPC: H01J29/07
Filed: 1989-03-29
Granted: 1993-01-19
Abstract: Abstract of the Disclosure The power handling capacity of non iron-based flat tensioned foil shadow masks for flat faceplate cathode ray tubes (CRTs) is enhanced by providing the flat tensioned mask (FTM) with a thin outer layer of iron, which is converted to iron oxide by blackening, or heating.  The iron layer, which is preferably at least 0.04 mil thick, is deposited on the FTM by electroplating in a ferrous ammonium sulfate bath-either before or after chemical etching of the FTM.  The thin iron layer increases FTM emissivity and reduces FTM doming at high electron beam energies.  The iron coating may be blackened in the frit-like cycle during CRT assembly or in a separate heating operation.  A blackened outer layer of cobalt may also be used to increase FTM emissivity.

Abstract: ABSTRACT OF THE DISCLOSURE         A fastening apparatus is provided wherein the length of a mating threaded connection between two members is limited as a function of an effective differential pitch to the uniform pitch of the threads on both members whereby clearances of progressive increasing amounts are established between successive opposed tooth flanks.  An elastic deformation of one member occurring in a direction opposite to the increasing of the amounts of clearance brings successive opposed flank portions into a force transmitting relationship whereby the total area of flank-to-flank contact between the threads varies as a function of the applied load.
