Title: Polyacrylonitrile particles by surfmer polymerization and sodium removal by chemical exchange
Inventor: WADE BRUCE E
IPC: C08F212/14
Filed: 1999-03-29
Abstract: The present invention is an acrylic polymer particle which is consistently and substantially spherical in shape and which has a mean diameter that can be predetermined from about 30 microns in diameter to about 5 microns or less. Polyacrylonitrile is synthesized in an aqueous dispersion polymerization with an ionic monomer or 'surfmer' to attain a narrow particle size distribution with a mean diameter as low as approximately 3Ò1.5 microns which is characteristic of an emulsion polymerization. The polymer comprises the ionic monomer and, optionally, a neutral comonomer. The mean particle size is dependent on the concentration of the ionic monomer present, the particular ionic monomer or monomers selected, and the counterion associated with the ionic monomers, the persulfate initiator, and the bisulfite activator. The counterions, often sodium ions, can be removed from the polymer particles by ion exchange with quarternary ammonium compounds.

Title: Polyaluminium chloride flocculants
Inventor: CLARKE NEIL
IPC: C01F7/57
Filed: 2000-12-08
Abstract: Polyaluminium chloride solutions may tend to be unstable in storage particularly those having a high basicity or charge density. This may markedly reduce the efficiency of the flocculant. The invention provides an aqueous polyaluminium chloride flocculant solution containing a stabilising quantity of a dissolved boron compound or compounds such as, for example, the boric acids or their salts. The stabiliser may be included during the production of the flocculant or to an existing flocculant.

Title: Internally illuminated sign assembled by shrinking
Inventor: WOODHOUSE ERIC GLYN
IPC: G09F13/04
Filed: 2000-12-22
Abstract: An internally illuminated sign 1, e.g. a road sign, comprises a translucent plastics face member 4 and an externally opaque body member 5 each having first and second parts 14,15 respectively of a locking means, the sign 1 being assembled by shrinking one member onto the other to allow the locking means to engage. The members 4,5 may be rotationally moulded, and the inside of the body 5 may include light reflecting material. One part 14 of the locking means may comprise an outwardly-projecting flange 17 carried on an upstanding collar 16, which co-operates with an inwardly-projecting flange 18 on the other part 15 of the locking means, with the member which carries the inwardly-projecting flange 18 being shrunk onto the other member. Alternatively, the face may comprise a flat sheet (4, figure 4) whose periphery (21, figure 4) forms the first part of the locking means, and which co-operates with a groove (20, figure 4) formed in the body (5, figure 4), with the body being shrunk onto the face. A method of forming an internally illuminated sign comprising the steps of forming, at an elevated temperature, a translucent plastics face member 4 having the first part 14 of a locking means, forming, also at an elevated temperature, an externally opaque plastics body member 5 having a second part 15 of the locking means, providing and maintaining a temperature difference between the two members, assembling them together and removing the temperature differential to secure the locking means, thereby forming the sign, is also described.

Title: Method of and device for detecting, ranging and classifying road users and obstacles
Inventor: GLOGER JOACHIM
IPC: G06V20/56
Filed: 2001-04-06
Abstract: A method of detecting road users and obstacles, determining their distance from an observer and classifying them employs a two-stage classification for identifying other parties representing a potential for a collision. In a first step, road users or obstacles are marked (2) in the image data 10 of a mono-image camera 1 and their distance and relative velocity 30 are subsequently determined so that potentially endangering objects can be selectively (4) subjected to a type classification 5 in real time.

Title: Method for forming a triple well of a semiconductor device
Inventor: RHO KWANG MYOUNG
IPC: H01L21/8238
Filed: 1997-12-24
Abstract: A method for forming a triple well of a semiconductor device. The triple well includes an n-well A, a first p-well B surrounded by the n-well A and a second p-well C spaced from the first p-well B and adjacent to the n-well A. The n-well A is formed by implanting impurities in a horizontal layer beneath the surface of the substrate, and then implanting impurities in a region above one end of the horizontal layer. Only one conductivity type of impurities need be implanted in each well. Therefore, it is possible to prevent a decrease of carrier mobility and an increase of the leakage current.

Title: Routing of data in a mobile IP system during change of agent
Inventor: OH SUK SANG
IPC: H04L29/06
Filed: 2001-11-14
Abstract: During movement of a mobile node 60 from a first foreign agent 40 to a second foreign agent 50, data packets received by the first foreign agent for the mobile node are buffered for subsequent transfer to the second foreign agent. The contents of the buffer are transferred to the second foreign agent when the change of agents is complete. The mobile node may notify the first foreign agent of the initiation of the change in agents. The arrangement prevents the need of a host 10 retransmitting data packets to the second foreign agent in a mobile Internet Protocol system.
