Abstract: An invoice processing system includes a requisition and catalog server (referred to as a Req/Cat Web, or RCW, server), a procurement services system (SAP), and a requester terminal (browser). ReqCat Web allows requesters to input requirements (requisitions) which ReqCat then passes to SAP, which creates purchase orders, sends them to vendors for fulfillment, receives the vendors invoices, and prepares the payments. Commodities may be designated as either receivable or non-receivable, and this designation is stored in ReqCat web and passed to SAP on inbound requisitions. Payments on invoices received for non-receivable items are approved via a positive confirmation process, and payments on invoices received for receivable items are approved via a negative confirmation process. Positive acceptance of an invoice by a requester of commodities triggers automatic generation of a goods received (move) ticket.

Abstract: A system for processing invoices including a front-end requisition and catalog system; a back-end procurement system; a scanner for scanning images of invoices; an image system and store for storing said scanned images and serving them to said workstation keyed to said invoice in connection with positive or negative confirmation processing of the invoice.

Abstract: A system and method for client/server communications, the method including the steps of loading to a client browser a frame set including a function frame and a content frame; loading application code to the function frame; and responsive to user interaction with the content frame, executing the application code. The frame set may also include navigation frame and a data accumulation frame. By using the frame set to store executable application code, collect and store data, and interact with a user, an application may be executed at a client browser substantially without client/server interaction beyond initializing the frames and communicating the end results.

Abstract: The content of a document is stored in a file system, while the profile of the document is stored in a messaging system. The profile of the document is accessed upon request, and the document content is accessed based upon the content of the profile.

Abstract: A breakdown dental forceps is provided in which the jaws are specifically designed to terminate in a flat and fine point which is capable of reaching down into extremely tight places which other dental forceps are unable to enter. The inner edges of the two jaws are also constructed to produce a concave surface on each which allows the jaws to firmly grasp irregularly shaped objects such as the mandibular molar roots. The finely tapered jaws and their concave inner surfaces allow the forceps to be used to grasp the mesial and distal surfaces of a molar which provide more gripping area and results in an easier extraction of the target molar. Additionally, the breakdown forceps is also designed in a manner that allows it to be taken apart which allows for the use of the lower handle and outer jaw or upper handle and inner jaw as a pry instrument used to loosen the mesial and distal roots of a sectioned molar which makes the extraction of those roots from the mandible significantly easier.

Abstract: Dialdehyde cellulose is produced by reacting cellulose in aqueous medium with meta periodate ion used in a molar ratio of from 1.2 to 12 moles of meta periodate ion per mole of cellulose at a temperature of from 36.degree. to 60.degree. C. and a pH of between 2 and the conversion pH of water soluble meta periodate to water insoluble para periodate, and separating the dialdehyde cellulose product from the reaction mixture.

Abstract: Di- and tricarboxy celluloses are hydrolyzed with sulfurous acid in an aqueous medium to a mixture of erythronic acid and glyoxylic acid, in the case of dicarboxy cellulose; to a mixture of meso tartaric acid and glyoxylic acid in the case of tricarboxy cellulose; and to a mixture of these three products, in the case of a feedstock comprising a mixture of di- and tricarboxy celluloses.

Abstract: Mixtures of oxalic, meso tartaric, glyoxylic and erythronic acids derived particularly from the oxidation of cellulose derivatives are separated from aqueous solutions in which they are contained and from each other by stepwise precipitation with calcium ion at controlled pH. The oxalic acid is precipitated as calcium oxalate at a pH of 0.9 to 2.0; the tartaric acid as calcium meso tartrate at a pH of 2.8 to 4.4; and the glyoxylic acid, as calcium glyoxylate at a pH of 4.5 to 5.4. After each precipitation the water insoluble precipitate is separated from the aqueous mixture in which it is contained. The relatively soluble erythronic acid remains in solution as a free acid, or in the form of its calcium salt.
