Title: Acetylation method for material containing cellulose, and manufacturing method for modified wood
Inventor: OHSHIMA YOSHINOBU
IPC: C08H8/00
Filed: 1994-06-23
Granted: 1997-12-30
Abstract: A acetylating agent vapor is brought into contact with a material containing cellulose while continuously moving the acetylating agent, and thereby, the material containing cellulose is acetylated in a vapor phase.  Solvents for dilution, catalysts, and an immersion process in an acetylating agent (liquid) are not necessary, and thereby, it is not merely the case that the process is simplified, but the acetylation period is shortened as a result of the increase in reaction efficiency, and the accumulation of excess heat of reaction in the material containing cellulose during the reaction is prevented, and thereby, the uniformity of acetylation is improved.  Furthermore, in the present invention, wooden strips acetylated by this method are accumulated and modified wood is manufactured.  This modified wood has superior resistance to moisture, possesses no acetic acid odor, and does not cause rusting.

Granted: 2004-08-03
Abstract: A method of forming porous articles with a varying pore distribution by extrusion from a billet with varying lubricant distribution. A single-polymer polytetrafluoroethylene is extruded and then stretched and sintered to provide a differential porous PTFE structure composed of fibers and nodes connected to one another by these fibers. The microfibrous structure has a portion within the cross section that possesses a different pore size, accompanied by a different node and fiber geometry, than adjacent areas within the cross section. A tube (10), having elongate nodes (12), fibrils (14), an inner surface (16) and an outer surface (18), of an expanded, porous fluoropolymer material, which is useful as a vascular graft, is formed. In a vascular graft, the pores taper inwardly, providing a fluid-tight lumen wall structure that prevents leakage, yet promotes cellular growth and natural tissue generation. A node structure of radially-oriented plates provides flexibility, suture strength, and enhanced protection against collapse.

Title: Medical and biological waste decontamination system
Inventor: KRALOVIC RAYMOND C
IPC: A61L15/46
Filed: 1994-02-25
Granted: 1998-12-01
Abstract: A bag (86) of medical or biological wastes is inserted into a chamber (12) that contains a grinder (20). A package (48) is placed unopened in the chamber with the wastes. A selected volume of a dilutant such as water is added to the chamber (40, 42). The chamber is closed and the grinder operated for a selected duration. The grinder grinds the packaging, disposing of the packaging and releasing liquid peracetic acid (70) and dry pH buffers (80) or permitting contained dry reagents (56, 58) such as acetylsalicylic acid and perborate to react with the dilutant, forming an anti-microbial solution with the dilutant. The grinder continues to grind the packaging and the wastes into fine particles forming a slurry with the anti-microbial solution. The continued operation of the grinder assures that the anti-microbial solution contacts all surfaces of the waste. In this manner, the medical or biological wastes are microbially decontaminated. A color indicator (60, 78) is included with the packaging to provide a color indication as to whether the anti-microbial reaction is complete. For example, a Gentian Violet may be provided which fades to white to indicate completion of the decontamination process. Once decontaminated, the slurry is removed from the chamber and disposed of as noncontaminated waste materials. Optionally, fragrances and deodorants may be included in the package.

Title: Automatic conference initiation upon all telephones for the conference being idle
Inventor: BALES BRUCE MERRILL
IPC: H04M3/56
Filed: 1995-12-07
Granted: 1999-06-29
Abstract: Telephone terminals provide an initiate conference feature. In response to actuation of a button, as each telephone terminal is dialed, a logical link is set up between an initiating telephone terminal and the dialed telephone terminal. Once all the terminals of the conference call are communicating with the initiating telephone terminal via logical links, the initiating telephone terminal waits until all of the other terminals are idle and then sets up a conference call that has the appropriate bandwidth for the type of conference call requested. Once a logical link has been set up to a telephone terminal, that telephone terminal lights the indicator associated with the initiate conference feature. A telephone terminal whose initiate conference indicator is lit can remove itself from the proposed conference by its own initiate conference button being actuated. Further, if two telephone terminals are engaged in a telephone call and a third telephone terminal is to be added to the call, the user of a first telephone terminal actuates the initiate conference button and dials the third telephone terminal. Once a logical link has been established to this third party, the user of the first telephone terminal rejoins the user of the second telephone terminal in the original telephone call. When the first telephone terminal detects that the third telephone terminal is idle via the logical link, a conference call is established between the three telephone terminals.
