Patent CA-2105351-A1 (CA)
Inventor: DERBY JEFFREY H
IPC: H04L12/66
Filed: 1993-09-01
Abstract: A system for interconnecting widely separated local area networks (LANs) by means of a wide area network (WAN) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point which allow subsequent data frames to be transmitted through the wide area network without such network level operations. More particularly, the various LANs are combined into search groups, represented by address prefixes, to which LAN-initiated connection requests can be broadcast and which can respond so as to establish the data path connections. This system has the connection flexibility of a prior art router and, at the same time, the low overhead of a prior art bridge. <IMAGE>

Title: Selective hydroxylation of phenol or phenolic ethers
Inventor: WASSON ROBERT C
IPC: C01B25/37
Filed: 1992-04-09
Abstract: Phenols, and related aromatic compounds, phenolic ethers, can be hydroxylated selectively using hydrogen peroxide in the presence of an amorphous or microcrystalline zirconium phosphate catalyst in a solvent containing an aliphatic carboxylic acid. The process is particularly suitable for phenol itself, and advantageously employs a partially dehydrated microcrystalline catalyst obtained by heating an hydrated microcrystalline zirconium phosphate for example at about 100 ·C. A convenient reaction temperature is 50 to 90 ·C, and convenient solvent is acetic acid. In an improved method of producing the catalyst, zirconium phosphate is precipitated from an aqueous phosphoric acid solution of zirconium oxychloride in the presence of a cationic phase transfer agent such as an alkylpyridinium salt or tetraalkylquaternary ammonium salt or a nonionic surfactant such as an alcohol ethoxylate.

Title: System for cleaning contaminated water
Inventor: GILLHAM ROBERT W
IPC: C02F9/00
Filed: 1992-04-24
Abstract: Water contaminated with halogenated organics, including chloroform, trichloroethane, solvents, pesticides, etc. is treated by passing the water through a permeable mixture of activated carbon and iron fillings. When the mixture is brought to a negative Eh voltae, the metal causes the contaminants to undergo chemical breakdown.  The activated carbon acts to retard the contami-nant, giving it a long residence time close to the iron. The negative Eh conditions demand oxygen exclusion, such that a favoured application is to place the mixture in a trench below the water table in an aquifer, in the path of a plume of contaminant. The mix-ture may also be contained in a tank above, or in, the ground. An inert filler material, such as sand, may be included in the mix-ture.

IPC: G02B27/22
Filed: 1992-09-21
Abstract: Imaginograph is an image (18) on a screen which is mathematically gen-eralised optical illusion to create psychological three dimensionality. These pic-tures are the would be "merged images in the brain" produced outside the brain. Rather than cresting one picture for the left eye and another for the right, an Im-aginograph is already the result of the analysed signals. Using the property that when one is looking at a flat picture, the brain superimposes the two substantial-ly the same images (19, 20) in the left and right eyes and produces the same pic-ture (21) in the brain. Imaginographs are pictures which are formed by superim-posing the left and right eye views at the same position as the object of interest in the view, keeping the images of the object of interest in the two pictures in regis-ter at all times. The left and right eye views and their projections can be genera-lised to obtain three dimensional views of non-Euclidean spaces.
