Title: Composition and process for treating metal
Inventor: STEINBRECHER LESTER E
IPC: C08K3/10
Filed: 1995-05-08
Abstract: Heating an aqueous mixture of a fluoroacid such as H2TiF6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can either be mixed with water soluble and/or water dispersible polymers, for example with dispersed polymers of the diglycidyl ether of bisphenol-A or an acrylic acid polymer, or with soluble hexavalent and/or trivalent chromium, to produce a composition that improves the corrosion resistance of metals treated with the composition, especially after subsequent painting. Another composition that improves the corrosion resistance of metals after contact with them is an aqueous solution of a mixture of: (A') a water soluble or dispersible polymer having at least one -OH group per polymer molecule selected from the group consisting of polyvinyl alcohol, polyethylene glycol, modified starch, and mixtures thereof, and (B') polymers and copolymers of acrylic and methacrylic acid and their salts.

Title: Bearing failure detection apparatus
Inventor: MACLEAN JAMES K
IPC: F16C17/24
Filed: 1998-03-19
Abstract: A warning device for the detection of a bearing malfunction in wheel assemblies of large commercial vehicles such as tractors and semi-trailers is disclosed. The warning device is preferably mounted on the stationary axle inside the wheel housing adjacent the brake mounting assembly to remain stationary. The device includes a probe which protrude outwardly so as to have a sensing end extend until it is a predetermined instance from the rotating brake drum, say 25-50 thousandths of an inch. As long as the brake drum is running true, the distance between the sensing end of the probe and the inner braking surface of the brake drum remains constant. If either wheel bearing becomes incapacitated for some reason which permits the brake drum to run out of true, the inner braking surface will contact the end of the sensing probe which activates a signalling device in the cab of the vehicle to alert the driver of the presence of a dangerous condition.

Abstract: The present invention provides a method for inhibiting an immune response and a method for inhibiting rejection of transplanted tissues. This method comprises preventing an endogenous molecule on a cell selected from the group consisting of gp39 and CD40 antigens from binding its endogenous ligand and preventing an endogenous molecule on a cell selected from the group consisting of CTLA4, CD28, and B7 antigens from binding its endogenous ligand. The prevention of such molecules from binding their ligand thereby blocks two independent signal pathways and inhibits the immune response resulting in transplanted tissue rejection.

IPC: C07C51/43
Filed: 1997-02-18
Abstract: Mother liquor, derived from a primary solids-liquid separation process (18) for separating aromatic carboxylic acid crystals from a slurry thereof in the mother liquor, is split into a recycle fraction (30) and a purge fraction (32). the recycle fraction (30) is returned to a reactor (10) in which the aromatic carboxylic acid is formed by liquid phase oxidation of a precursor thereof. The purge fraction (32) is concentrated in evaporator (42) to recover solvent and produce a residue for disposal or further treatment. Before concentration the purge fraction (32), it is subjected to solids-liquid separation in filtration unit (34) to remove fine solids thereby reducing the load on the evaporator (42) and facilitating the recovery of greater amounts of the solvent along with recovery of aromatic carboxylic acid fines, e.g. for recycle to the reactor (10).
