Granted: 1998-08-04
Abstract: A more environmentally compatible package (10) containing one or more stacks of compressed flexible articles (20). For products such as single use absorbent baby diapers, catamenial pads, incontinent briefs and the like, the degree of compression within the bag may be as much as 50 % or more when compared to the uncompressed thickness of the articles. In a particularly preferred embodiment, the bag totally encloses a stack of compressed flexible articles and exhibits a substantially rectilinear shape. The bag preferably includes an integral carrying device (71). The side panels (30 and 31) and the front and back panels (40, 41) of the bag are subject to tension imposed by the stack of compressed flexible articles. A line of weakness at least partially spanning a tensioned side panel of the bag is provided and functions as an opening device. The line of weakness is coated with a layer of reinforcing material preferably comprised of polyvinyl alcohol to prevent premature rupturing of the opening device. The opening device (17) allows the compressive forces acting upon the flexible articles contained in the bag to be at least partially released when the opening feature is activated by the end user. Partial separation or complete removal of a portion of the tensioned side panel (17) of the bag allows the coinciding portion of the stack of compressed articles to project in a fan-like array through the aperture thus created to permit easy one-at-a-time or multiple removal. Polyvinyl alcohol of the type used to reinforce the opening feature may, if desired, also be used as a sealant for assembling the bag and to provide additional support for the carrying device.

Abstract: An assembly/disassembly system is comprised of a cell assembly and a cell disassembly, each assembly having one buffer memory with its memory area logically divided into a plurality of data areas (banks).  The cell assembly receives TDM data to assemble ATM cells by storing the TDM data into the respective banks according to the virtual channels.  When one of said banks stores the TDM data in the payload length of an ATM cell, an new bank (unused bank) is specified to store the TDM data successively.  An ATM cell is formed by using the data read out from the bank where the TDM data is stored in the payload length of an ATM cell.  The cell disassembly receives ATM cells from the ATM highway to disassemble the ATM cells into TDM data by using the buffer memory.  The payload of a received cell is stored into an unused bank. A chain of the bank addresses each storing the payload of the received ATM cell is formed for each virtual channel of received ATM cells. According to a bank address read out from the chain corresponding to each channel of the TDM highway, the data as the TDM data is read out from the buffer memory.

Granted: 2000-07-18
Abstract: There is disclosed a novel process for catalyzation for trapping of a catalyst metal involved with the adhesion of an electroless plating to a substrate. The process is carried out by employing neither the sensitizing-activating method nor the catalyst-accelerator method.            Specifically, in forming an electroless plating on the surface of a non-conductive substance as a substrate, the surface of the non-conductive substance is coated with a treatment liquid containing at least chitosan or a chitosan derivative before the steps of catalyzation and electroless plating to form a hydrophilic coating film on the surface of the non-conductive substance.  The hydrophilic coating film traps and fixes thereon a catalyst metal such as palladium through chemisorption thereof by the action of chitosan or the chitosan derivative.  As a result, a state that a sufficient amount of the active catalyst is borne on the surface of the substrate can be secured in the step of electroless plating to enable the electorless plating strong in adhesion to the substrate to be uniformly and efficiently formed on the surface of the substrate.

Granted: 2000-01-04
Abstract: The present invention discloses a method and apparatus for cyclically accelerating the leading end of a slower moving first material web to match the faster speed of a continuous second material web. The apparatus is comprised of a set of upstream metering rolls which feed the first material web at a constant slow speed, a set of downstream applicator rolls having a constant and relatively faster rotational velocity, and an acceleration mechanism which variably and alternately reverses and allows forward movement of a leading end segment of the first material web while allowing for the constant rotational velocities of the upstream and downstream rolls. The first material web is wrapped partially around the set of upstream rolls and the leading end segment thereof is wrapped partially around one of the downstream rolls. The acceleration mechanism is juxtapositioned between the upstream rolls and the downstream rolls in the feed path of the first material web. A cutting mechanism is provided for cutting a segment of predetermined length of the leading end segment of the first material web when the leading edge has been accelerated to match the speed of the downstream roll. The cut segment is thereafter applied by the applicator roll to the faster moving second material web. Thus, the present invention provides for matched speed cutting and matched speed application of a slower velocity first material onto a faster velocity second substrate material.

Title: Lath cutter and placer
Inventor: GRINDER DANIEL A
IPC: B27M3/00
Filed: 1996-09-24
Granted: 2003-11-25
Abstract: A strip cutter system combined with a strip placer is disclosed.  Strips are used in the packaging of finished lumber to provide lateral stability and shear strength to the stacked package. The strips are cut from surplus lumber and are dispensed onto the lumber package simultaneously as they are cut, thereby eliminating the need to cut bundle, store, handle and load strips into a strip dispensing device. The raw material "blocks" for the strips consists of lumber of nominal 2" thickness and any width, trimmed to approximately four feet long to match the width of thelumber package. Such material is readily available as a by-product in any lumbermill. The blocks are loaded on edge into a storage pocket on the top of the strip cutter and placer so that the bottom edge of the bottom block bears by gravity against stops in the cutting zone. The blocks may be softened by pre-conditioning in hot water, steam or by heating methods such as microwave and/or electric heating elements.  When a strip is required, a sharp knife the length of the block is drawn laterally across the bottom edge of the block slicing off a strip approximately 1/8" thick.  The strip falls by gravity onto the top of the lumberpackage while retained between guides which extend from the lower side of the strip cutter and placer and rest on the top of the lumber package.  Alternatively, a lowering device may be added to receive the strip as it is cut and then lower itand place it onto me top of the lumber stack. Additionally, a sweeping device may be added to move a defective strip to one side and allow a second strip to be placed next to it.  The number of strip cutter and placer units on a complete system depends on the maximum number of locations on a stack of lumber at which strips would be placed on one tier of lumber.
