Patent number: 6096407Abstract: A built-in packing for the material exchange and/or heat exchange between gases and liquids is composed of a plurality of undulating lattice-like elements arranged next to each other and each mounting element has channels formed by the undulations extending at an angle relative to the vertical direction and extending parallel to each other, wherein the channels of always two adjacent mounting elements intersect each other. Continuous longitudinal struts are provided at the bottom of the channels, wherein the longitudinal struts have contact plates at the ends thereof, and wherein the contact plates are components of an upper and a lower horizontal closed edge strip. The longitudinal struts are connected through transverse struts in a framework-like manner, wherein the transverse struts extend in horizontal planes which extend parallel to the two edge strips.Type: GrantFiled: July 31, 1998Date of Patent: August 1, 2000Assignee: GEA Energietechnik GmbHInventors: Vladimir Vodicka, Arno Katzmann

Patent number: 6083580Abstract: A container having walls made of a paper/plastic laminate having a cardboard core sandwiched between inner and outer face liners, wherein at least one of the face liners is comprised of a face liner laminate. The face liner laminate is composed of an exterior ply of oriented synthetic plastic film whose opposing surfaces are rendered wettable by corona-discharge treatment, and a base paper ply is cold-laminated to the film ply and adhered to the core of the board. The cardboard core may be a fluted medium of corrugated paper board, or it may be a planar stiff paper core. The invention is also directed to a structural member for use in making inexpensive furniture comprising a supporting member and a cardboard core laminated to a face liner laminate. The film ply of the laminate enhances the strength of the container or structural member and imparts water resistance thereto. Because the exposed surface of the film ply is printable, it may have decorative graphics or other printed matter applied thereto.Type: GrantFiled: April 20, 1998Date of Patent: July 4, 2000Inventors: Arnold B. Finestone, Gilbert Bloch

Patent number: 6039184Abstract: A flexible protective article for engaging a surface of a product for protecting the product from shock during shipment comprising a member formed of a sheet of material of molded pulp having a substantially uniform thickness throughout. The member has a plurality of generally parallel spaced apart flutes formed therein of a substantially uniform thickness extending at an angle between 15.degree. and 75.degree. with respect to a first imaginary plane extending through the flutes and extending inwardly and outwardly with respect to the first imaginary plane. Each of the flutes in a normal unloaded position has first and second legs angled with respect to each other and terminating in an apex. The first leg has a first length and the second leg has a second length. The second length is less in length than the first length. The first and second legs extend at angles on the same side of a second imaginary plane extending perpendicular to the first imaginary plane and extending through the apex.Type: GrantFiled: December 8, 1998Date of Patent: March 21, 2000Inventor: Gregory W.

Patent number: 6037033Abstract: The present invention is directed to a unique thermal insulation panel. More specifically, the present invention is directed to a vacuum insulated panel formed of a highly impermeable evacuated envelope that is supported by a thermal barrier made of a macro-structural support structure having a cell or void size of 0.5 micron or greater. Preferably, the panel includes a getter material. Further, the present invention is directed to a thermal insulation barrier of a macro-structural structure. Preferably, the barrier is formed of elements having a geometric shape of a repetitive three dimensional design that permits stacking of one thermal insulation element with another thermal insulation element having a complimentary geometric shape, and which locks movement of adjacent thermal insulation elements in at least one of the directions 90.degree. to the stacking direction.Type: GrantFiled: July 7, 1997Date of Patent: March 14, 2000Inventor: Rick Cole Hunter

Patent number: 6015601Abstract: The present invention relates to a self-sealing flexible plastic valve for a non-latex balloon, to a balloon incorporating such a valve, to a method of manufacturing such a valve, and to a method of manufacturing a balloon incorporating such a valve. The valve is made from two flexible plastic strips, bonded together along the side edges to define a valve passageway or tube, and having an open inlet end and an open outlet end. The inlet end of one or both valve strips flares or otherwise curls outwardly to facilitate opening of the valve to insert a gas supply mechanism to inflate the balloon.Type: GrantFiled: August 7, 1998Date of Patent: January 18, 2000Assignee: Convertidora Industrial S.A. de C.V.Inventor: Arturo Verduzco Garcia

Patent number: 6004651Abstract: A composite slab made of plastic, especially polypropylene, for construction purposes and packing purposes for example is described, said slab according to a preferred embodiment comprising a plurality of layers, each of which consists of a composite that is extruded in a plurality of layers and of which two plane layers and the others are profiled, namely layers that have a corrugated profile with peak lines that are located in a plane, with these layers being welded together along the peak lines on one side of the profiled layer and/or at the intersections of the peak lines of adjacent profiled layers. Layers consisting of a plane slab can be provided between the profiled layers. The composite extruded in several layers comprises two outer layers and a middle layer made of polymers from the same material group, whose middle layer consists of a highly crystalline polymer with incorporated stretch-resistant fibers, whose melting point is at least 15.degree. C.Type: GrantFiled: January 20, 1998Date of Patent: December 21, 1999Inventors: Max Joseph Graf von Montgelas, Udo Finke, Karl Harald Erlinghagen

Patent number: 5993501Abstract: A composite filter media includes a fibrous filtration layer of randomly oriented fibers and one or more pleatable stiffening layers which enable the composite filter media to be pleated and hold or retain its pleats. The pleatable stiffening layer(s) may enhance the dirt holding capacity of the composite filter media especially when positioned upstream of the fibrous filtration layer. The composite filter media may also include a flexible covering layer which functions to block the loss of fibers from the fibrous filtration layer. Preferably, the mean fiber diameter of the fibers in fibrous filtration layer increases and the density of the fibrous filtration layer decreases throughout the thickness of the fibrous filtration layer from one major surface to the other major surface of the fibrous filtration layer.Type: GrantFiled: February 17, 1998Date of Patent: November 30, 1999Assignee: Johns Manville International, Inc.Inventors: Michael John Cusick, Fred Lee Jackson, Charles Francis Kern, Craig Donald DePorter
