Title: Method of seasoning lumber
Inventor: IZUMI HYOGO
IPC: F26B9/06
Filed: 1992-03-04
Granted: 1997-08-19
Abstract: A method of seasoning lumber without the occurrence of cracks or warps by raising the turnover ratio of the dryer. In the first step, the lumber is placed into a pressure vessel, and after unifying the temperature within the lumber by charging and discharging of saturated steam in the vessel and fluctuating the steam pressure for pressurizing, the saturated steam maintaining the unified temperature in the vessel is discharged, and by boiling and evaporating the water contained in every tissue of the lumber, it is formed into a state that can be seasoned uniformly. Secondly, the lumber is seasoned by discharging the free water contained in the lumber removed from the pressure vessel. Thirdly, the lumber of which free water is evaporated is placed back into the pressure vessel, and by forming the current of the superheated steam within the vessel, the lumber is pressurized and heated, thus eliminating the contained water. The invention provides no moisture content gradient and no tendency to form moisture content gradient in the lumber.

IPC: B42D15/00
Filed: 1993-02-18
Granted: 2005-01-18
Abstract: A system for organization, inventory control, and reordering of hardware items or the like. The system includes a rack to organize cartoned hardware items for easy access. End panels attached to each side of the rack displays the complete line of hardware available.      Each carton includes a label attached to the carton's face. The label includes one portion that displays indica representing the particular item, e.g. a drawing of the hardware type, a description of the contents, and quantity. Each label also has a detachable perforated portion which may be peeled off from the carton and has a reusable pressure-sensitive backing. Order forms related to the labels of each hardware carton are also provided.      Thus, when a carton is low, the user simply removes the perforated portion of the label from the face of the carton and affixes it to the order form to complete the order.

Title: Check valve catheter
Inventor: YOUNG THOMAS M
IPC: A61M25/00
Filed: 1991-09-13
Granted: 1996-08-20
Abstract: A valved catheter having an elongated, flexible tubular element (12) extending along a central axis (A) and a flow portion of a valve assembly (10) which controls fluid flow in the tubular element. The element is adaptable for bidirectional flow of fluid between its proximal (14) and its distal (16) ends, with a bidirectional valve assembly (24) coupled to the interior of the tubular element. The bidirectional assembly generally defines a control plane (26) which intersects the central axis at an oblique angle. Theassembly has an inflow portion (53) and an outflow portion (55) nominally disposed to lie in the control plane. The inflow portion includes an inflow vane (56) positioned between the intersection of the control plane with the central axis and the distal end and which is adapted to be deflected out of the control plane toward the distal end in response to the establishment of a rela-tively high fluid pressure at the proximal end and a relatively lower fluid pressure at the distal end. The outflow portion also in-cludes an outflow vane (58) positioned between the intersection of the central plane with the central axis and the proximal end and which is adapted to be deflected out of the control plane toward the proximal end in response to the establishment of a rela-tively low fluid pressure at the proximal end and a relatively higher fluid pressure at the distal end.

Abstract: Method of making a twisted conductor wire unit in which each wire of the pair is individually insulated.  The twisted pair is provided with an outer extruded polymeric layer while a vacuum is applied to the pair at the extrusion position.  The vacuum draws the polymeric layer down onto the pair and forces the insulated wires together along the length of the unit.  This avoids spaces being provided between the insulated wires in the finished structure and provides a substantially constant distance between the wires to improve electrical and cross-talk characteristics.

Title: Manufacture of metallic strip
Inventor: FOURIE EUGENE
IPC: B21B37/24
Filed: 1994-02-11
Granted: 2002-01-01
Abstract: A method and apparatus for manufacturing metallic strip (20) with a varying thickness is described. The metallic strip is particularly for use as part of a windscreen wiper blade assembly. Feedstock (14) having a constant thickness and width is passed in a cold condition through a pair of opposed forming rollers (16, 16) and the separation of the rollers is varied thereby deforming the feedstock in a varying manner along the length thereof to provide formed strip with a varying thickness. The rollers (16, 16) have parallel axes with one axis being fixed and the other axis being displaced back and forth. The thickness of the formed strip varies in a ratio of 3:1. The formed strip is heat treated in a varying manner. The amount of power supplied to heat the strip varies in accordance with the thickness of the strip. A preferred roller arrangement (15) has a pair of rollers with each roller being supported by bearings located intermediate its ends to provide an exposed end portion, with the rollers being offset and with the end portions overlapping. The overlapping end portions define a rolling region between them.

Title: Spiral flex tree fastener
Inventor: SULLIVAN KATHLEEN A
IPC: F16B15/06
Filed: 1995-08-30
Granted: 1999-05-18
Abstract: A spiral flex tree fastener for use in securing a component to a panel by insertion into a hole provided therein has a head, and a shank extending axially therefrom and ending in a conical rounded point.  The head shank and point share a common axis, the head naturally being of greater diameter than shank and point.  The point has a maximum diameter substantially equal to the hole into which the fastener may be inserted.   The shank  is flattened, has two sides and a flange running axially along each of the two sides.  The shank has a diagonally measured width equivalent to the maximum diameter of the point and merges smoothly thereinto, and the flanges ensure that the fastener remains centered in the appropriately sized hole into which it may be inserted.  On each side of the shank are a plurality of flexible fins set at an oblique angle with respect to the axis of the fastener.  A portion of each fin extends radially outward from the axis of the shank beyond the radial extent of the conical rounded point.  The fins flex against the walls of the appropriately sized hole, securing the fastener therein, and are shaped to make its nondestructive withdrawal, if desired or necessary, possible but more difficult to effect than its original insertion.

Title: Water repellent surface treatment with integrated primer
Inventor: GOODWIN GEORGE B
IPC: C08J7/04
Filed: 1995-10-24
Granted: 2000-01-04
Abstract: An article is disclosed comprising a substrate of glass, plastic, metal, organic polymer coated substrates and inorganic coated substrates, wherein at least a portion of the surface of the substrate is treated with a composition comprising a mixture of perfluoroalkylalkylsilane and a completely hydrolyzable silane.  The perfluoroalkylalkylsilane provides rain and soil repellency to the substrate surface, while the fully hydrolyzable silane hydrolyzes and condenses to form silica, which imparts resistance to weathering and abrasion, thus improving the durability of the rain and soil repellency properties.  The method of providing such a durable rain and soil repellent surface comprises contacting the substrate surface with a composition comprising perfluoroalkylalkylsilane and fully hydrolyzable silane, and may include first depositing a layer of silica on the substrate surface, then contacting the substrate surface with a composition comprising perfluoroalkylalkylsilane and fully hydrolyzable silane.
