Title: Rigid end socket for flexible tubing and method of making same
Inventor: KRAMER VANCE M JR
IPC: F16L55/11
Filed: 1995-08-10
Abstract: A rigid end socket is formed on a length of flexible rubber tubing for receiving a tube coupler or a radially expandable end plug in a tightly retained manner.  The end socket is formed by placing a sleeve of uncured rubber on a forming mandrel and then placing a rigid collar over an end of the sleeve spaced somewhat from the end.  The outer length portion of the sleeve is folded over the collar to enclose the collar between an inner length portion and the outer length portion. Then the resulting product is cured to produce a flexible tube with a rigid socket at one end.

Title: Custom product estimating and order processing system
Inventor: DUDLE JAMES
IPC: G06F16/25
Filed: 1995-08-18
Abstract: A system and method for generating specifications, estimates and orders for the manufacture of custom items such as business forms is provided which stores estimate data at a central location, e.g., a corporate office, for access by sales representatives at remote sales sites.  A sales representative creates an item specification for a form to be manufactured and electronically transmits it to the  corporate  office  to  obtain  estimate  data.    Data relating to the cost and list price to produce the form based on the item specification is transmitted to the sales representative.  The sales representative determines a sell price from the pricing data, and generates a production order using the item specification and the estimate data, among other data.  The production order is transmitted to a manufacturing plant  for  job execution.   The  system manages a centralized repository of item specification, estimate and customer contract data, among other types of data, for analysis and reporting which can be accessed by computers  at  the  corporate  office(s)  and  different manufacturing plants and sales sites.

Title: Wound measurement device and method for its use
Inventor: SESSIONS ROBERT W
IPC: A61F13/00
Filed: 1996-03-04
Abstract: Device and related method for determining the surface area of a wound.  The device comprises a transparent sheet having a series of perforations defining first and second sections of the sheet which allow the first and second sections to be separated from one another along the perforations.  The transparent sheet is folded along the perforations so that the two sections overlap each other, and the sections are substantially free of adhesive material.   The second section includes indicia thereon which allow a user to determine the surface area of a wound after the outline of the wound or opening is traced thereon.  Upon use, the device is placed over the wound or opening, with the first section toward the wound or opening, and the outline of the wound or opening is traced onto the second section.  The second section containing the marked outline of the wound, which was isolated or shielded from contact with the wound, is then separated from the first section along the perforations, allowing the second section to be immediately handled by a person, i.e., without subjecting the second section to cleaning or sterilization.

Patent CA-2176775-A1 (CA)
Inventor: BAKER BRENDA SUE
IPC: G06F17/30
Filed: 1996-05-16
Abstract: A system and method for selectively controlling database access by providing a system and method that allows a network administrator or manager to restrict specific system users from accessing information from certain public or otherwise uncontrolled databases (i.e., the WWW and the Internet). The invention employs a relational database to determine access rights, and this database may be readily updated and modified by an administrator. Within this relational database specific resource identifiers (i.e., URLs) are classified as being in a particular access group. The relational database is arranged so that for each user of the system a request for a particular resource will only be passed on from the local network to a server providing a link to the public/uncontrolled database if the resource identifier is in an access group for which the user has been assigned specific permissions by an administrator. In one preferred embodiment, the invention is implemented as part of a proxy server within the user's local network.

Patent CA-2185324-A1 (CA)
Title: Treating inflammation via the administration of specific sulfatase enzymes and/or sulfation inhibitor
Inventor: ROSEN STEVEN D
IPC: A61P3/08
Filed: 1995-03-15
Abstract: Compositions are administered to a patient (preferably by injection and locally) to treat a variety of conditions including inflammation associated with trauma and with certain aspects of diseases such as rheumatoid arthritis, psoriasis, insulin-dependent diabetes, cutaneous lymphomas, duodenal ulcer, chronic proctitis, lymphocytic thyroiditis, hemorrhagic shock, reperfusion injury during transplantation and multiple sclerosis. The compositions are pharmaceutically acceptable injectable formulations which include an active component in a pharmaceutically acceptable carrier. The active component is a chlorate or selenate which inhibits the natural biochemical sulfation process and/or a sulfatase enzyme which removes a sulfate from a specific position of a saccharide molecule which makes up a part of a natural ligand for L-selectin. Removal of the sulfate from the ligand hinders the ability of the ligand to bind to its natural receptor (i.e. L-selectin) and thereby hinders a biochemical chain of events which results in inflammation.

Title: Support for growing/regenerating plant and method of growing/regenerating plant
Inventor: TANZAWA HIROSHI
IPC: A01G31/00
Filed: 1995-06-20
Abstract: A plant is grown or regenerated while suppressing the propagation of bacteria and fungi, by use of a carrier comprising a culture medium and a polymer constituting a network structure wherein the culture medium is substantially absorbed into and retained by the network structure in a proportion of 10 % to 100 % of the equilibrium culture medium absorption of the polymer constituting the network structure.     The propagation of bacteria and fungi is much faster, and the metabolic rate thereof is much larger, than those of a plant, and therefore the necessity of the supplement of a nutrient (such as water and saccharide) from the culture medium to the bacteria and fungi is much greater than that in the plant tissue. The culture medium which has been absorbed in the network structure comprising the polymer is hardly available to the bacteria and fungi having a high metabolic activity, unlike a usual liquid medium, but on the other hand such a culture medium is available to a plant tissue having a low metabolic activity, substantially equally in the case of the usual liquid medium, whereby the propagation of bacteria and fungi is effectively suppressed substantially without affecting the growth or regeneration of the plant.
