Title: Conveyor belt
Inventor: TINGSKOG LENNART
IPC: B65G15/08
Filed: 1991-12-23
Abstract: A conveyor belt, which is made of an elastic material, comprises a flat centre piece (2) which is flexurally rigid about the longitudinal axis of the belt owing to a transverse reinforcement (8, 9b) and is but slightly extendible in the longitudinal direction owing to a longitudinal reinforcement (10); two flat edge pieces (3, 4) which are each articulated to one side edge of the centre piece (2), are flexurally rigid about the longitudinal axis of the belt (1) owing to a transverse reinforcement (8, 9a, 9c), are extendible in the longitudinal direction of the belt, and together have a width at least equal to the width of the centre piece;  and two link pieces (5, 6) which connect each edge piece (3, 4) with the centre piece (2), are flexible about the longitudinal axis of the belt (1) and extendible in the longitudinal direction of the belt, are resilient to enable outward pivotal or folding movement of the edge pieces from a position in which they are folded over the centre piece, and have a width substantially smaller than that of the centre piece. A longitudinal strip (11), which is fixedly connected to one side of the centre piece (2) and projects upwardly therefrom, is extendible in the longitudinal direction of the belt (1). The height of the strip is smaller than or essentially equal to the width of the link pieces (5, 6), and its transverse position on the centre piece is such that the edge pieces (3, 4), when folded over the centre piece, are applied against the strip.

Title: Gas-phase process for producing copolymer of propylene and ethylene and polyolefin films made therefrom
Inventor: KLIMEK THADDEUS W
IPC: C08F4/652
Filed: 1993-11-05
Abstract: ABSTRACT The present invention relates to an improved gas-phase process for producing in-situ TPO's or copolymers of propylene and ethylene in multiple reactors using high activity Ti/Al catalysts is provided.  The improvement consists of developing a control parameter derived from eight integral regions of the copolymer 13C NMR spectrum, defining the limits of the control parameter for the process, and operating the process to maintain the parameter within the defined limits.  This is accomplished by adjusting the amount of ethylene fed to the reactors and adjusting other process variables as required.          The present invention is further directed to tough, puncture- and tear-resistant films having a high degree of flexibility and softness are provided.  The monolayer and multilayer films of the invention are obtained using copolymers of propylene with 8 to 40 weight percent ethylene produced by gas phase polymerization of the monomers in dual reactors.  The films will have a 1% secant modulus from 5,000 psi to 70,000 psi.  Melting points of these films are higher than that of low density polyethylene and, most generally, in the range 125°C to 160°C.

Title: Plugged base pipe for sand control
Inventor: RESTARICK HENRY L
IPC: E21B43/08
Filed: 1993-09-24
Abstract: PLUGGED BASE PIPE FOR SAND CONTROL            ABSTRACT      The flow apparatus of a perforated mandrel are temporarily sealed by plugs which are made of a sacrificial material, for example, zinc, aluminum and magnesium.  The plugs prevent dirty completion fluid from passing through the screen as it is run into the hole, thereby protecting the screen from plugging.  While the screen mandrel is temporarily sealed by the plugs, cleaning fluid is circulated through a work string and is returned through the annulus between the screen and the well bore for removing filter cake, drilling debris and lost circulation material.  After the annulus has been cleaned, it is filled with an acid or caustic solution, which dissolves the sacrificial plugs.  In an alternative embodiment, each sealing plug has a vent pocket sealed by a stub portion which projects into the mandrel bore.  The screen mandrel flow apertures are opened by mechanically shearing the stub portion of each sealing plug.

Title: Expansion Foam Borehole Plug and Method
Inventor: RAJKOVICH RICHARD A
IPC: E21D5/00
Filed: 1993-12-03
Abstract: A borehole decking plug which is created by a self-expanding plastic foam.  Two closed waterproof pouches, an inner pouch and an outer pouch, each contain a separate component of the foam.  The inner pouch is contained within the outer pouch, and both are contained within a third open external pouch having a tether attachment.  Upon breaking the inner pouch, the separate foam components combine within the outer pouch to form a complete expansion foam.  The foam expands slowly enough to provide sufficient time for the device to be lowered via the tether down a borehole to a preselected position.  Once in position, the expansion foam bursts the outer pouch and escapes upward through the external pouch to form a deck plug at the preselected position.

Title: In vitro antibody perfusion of kidney grafts
Inventor: TAUBE HIRSCH D
IPC: A61P37/06
Filed: 1992-10-15
Abstract: In vitro treatment of a kidney prior to transplantation into a human recipient to reduce the risk of rejection, comprises perfusing the kidney with a solution of antibody specific to passenger leukocytes (e.g. anti-CD45 antibody) under cold ischaemia (CI) conditions with the renal vein occluded, and incubating the perfused kidney under CI conditions for at least 20 minutes. The volume of perfusion liquid is preferably at least 50 ml and the concentration of mAb about 40 µg/ml or more. This has been found to increase mAb uptake by the target cells and the extent of mAb saturation of the target cells, and seems to be associated with a reduced incidence of graft rejection.

Title: Pattern recognition with a tree structure used for reference pattern feature vectors or for hmm
Inventor: WATANABE TAKAO
IPC: G10L15/32
Filed: 1994-06-01
Abstract: Preferably using frame vectors, a reference memory (13) keeps feature vectors of a set as a tree comprising a root node, leaf nodes farthest from the root node, and intermediate nodes with the frame vectors assigned respectively to the leaf nodes. A calculator (17) calculates cluster distances between each feature vector of an input pattern and a subset assigned among the set to each daughter node of a mother node which is first the root node. From the intermediate nodes with the mother node successively selected along each branch of the tree, a selector (19) selects at least one daughter node that gives a shortest possible cluster distance. Controlling the calculator and the selector to use the cluster distances starting at each node selected nearest to the root node and proceeding along the branches to one of the leaf nodes that are used as daughter nodes of mother nodes selected nearest to the leaf nodes, a pattern distance calculator (15, 23) calculates pattern distances between the input pattern and reference patterns represented by the set. If the branches do not reach such leaf nodes, the cluster distances are used to the mother node last selected.      Frame distributions of HMM may be used instead of the frame vectors.
