Title: System and method for automated payment and adjustment processing
Inventor: KONG XIANG
IPC: G07F17/42
Filed: 2004-09-14
Abstract: A system and method for automated adjustment processing using pre-configured sets of business rules is provided. The seller pre-configures a set of business rules for use in processing an adjustment for a specific buyer. The set of business rules may be variable for each buyer and/or globally set. When a payment is received from a seller and an adjustment is required, an adjustment management application retrieves the buyer's set of business rules from the seller. The set of business rules are then applied to attempt to match the received payment to one of the buyer's outstanding invoices. If the match is successful, the buyer's payment is processed.

Patent CA-2548643-A1 (CA)
Inventor: HIROSE THOMAS
IPC: A61K35/28
Filed: 2004-04-07
Abstract: A system provides individualized "baseline" or internal "control" for an individual by collecting cells from the individual at an earlier time point prior to the onset of disease, which can be used as a standard for normalcy and a benchmark or reference for measuring the progression or development of any process the cells undergo. This allows study of biophysical, biochemical, architectural, morphological, functional, or physiological differences between cells collected from an individual at one time to cells collected from the same individual at a later point in time. The comparison between cells collected at different times allows for the study of relative responses of these cells when treated with a variety of chemicals. With this system disease markers can be determined that can aid in diagnosis and discovery of therapeutics for the disease of interest. As a result, this system may provide a basis for the production of patient-specific, as opposed to disease-specific drugs.

Title: Guided retractor and methods of use
Inventor: LARSON JEFFREY
IPC: A61B17/02
Filed: 2004-12-08
Abstract: The present invention provides methods and apparatus in which a surgical retractor comprises a plurality of mechanically coupled tissue retaining walls that are guided into position along one or more guides previously implanted into the patient. The walls are preferably coupled by pivots, so that separating some of the walls from one another opens an operating space. There are preferably two guides, which are driven or screwed into the pedicles of vertebrae, or other bone. Since practical considerations will usually mean that the guides are not generally parallel to one another, the guides are capable of polyaxial movement with respect to the pedicles, and retractor is provided with oversized channels to receive the guides. The channels may be conveniently disposed tin a frame, which also serves to hold lock the walls apart. Various convenience features are contemplated including a web disposed between the walls, which expands as the walls are separated. Also contemplated are projections from near the bottoms of one or more of the walls, which can alternatively or additionally help to hold the underlying tissue in place.

Title: Flame-retardant mixture for lignocellulose composites
Inventor: RAETZSCH MANFRED
IPC: C08H8/00
Filed: 2004-12-17
Abstract: The invention relates to a flame-retardant mixture for lignocellulose composites comprising 60 to 90 percent by weight of particulate and/or fibrous lignocellulose materials and 40 to 10 percent by weight of a flame retardant concentrate that is immobilized on and/or in the particulate and/or fibrous lignocellulose materials acting as carriers. Said flame retardant concentrate contains flame retardants of the boric acid type and/or the salts thereof, melamine resins, optional synergists, and other additives. The flame retardants are chemically coupled to the melamine resins while the flame retardant concentrates are immobilized on and/or in the carrier substance of the particulate and/or fibrous lignocellulose materials. The flame retardant mixture can be produced using a liquid impregnation method, a melt impregnation method, and a liquid impregnation-solid mixing method. Flame-resistant lignocellulose composites can be produced by melt-processing mixtures comprising 40 to 95 percent by weight of flame retardant and 60 to 5 percent by weight of duromer prepolymers, the duromers being hardened. As flame-resistant semifinished products and molding materials, the inventive lignocellulose composites provide great resistance against infestations by insects, fungi, and mold while the flame-retardant mixture is provided with great resistance against washing out. Preferably, said lignocellulose composites are suitable for exterior applications in the construction and leisure sector.

IPC: G06F17/30
Filed: 2004-12-10
Abstract: A distributed computer system has computers storing data items each data item being assigned to one of a plurality of virtual directories. Each computer has at least one node of a virtual network (10) for directory look-up, with linking data comprising addresses of other nodes associated with the same virtual directory and software that, in response to an enquiry message either replies, identifying itself or forwards the message to another node of the network (10), according to whether the node is or is not associated with the directory specified in the enqiry message. Similarly, each computer has, for each item that it stores, a node of a virtual network for item look-up, with linking data comprising addresses of other such nodes associated with items assigned to the same virtual directory, so that these linking data together define a plurality of virtual networks for item look-up, each of which networks corresponds to a respective different virtual directory. The node also has software that, in response to an enquiry message either replies with the item sought (or identifying itself for later item retrieval) or forwards the message to another node of the network , according to whether the node is or is not associated with the item specified in the enqiry message. For use in this system, or separately, a retrieval mechanism for thereby the addresses (25) of multiuple nodes matching the same directory name (or other label) is described. Each node matching a given label (21a) has associated with it a data storage area for containing the label and is responsive to enquiry messages to return a list of addresses of other nodes matching the same label.  First retrieval means responds to input of a label to identify the address of a node matching that label, and second retrieval means then sends an enquiry message to the address identified by the first retrieval means and upon receipt of a response to iteratively sends further enquiry messages to the node having the addresses contained in the response to that enquiry message or as the case may be in a response to a subsequent enquiry message.
