Title: Acidic gas sensors
Inventor: PLETCHER DEREK
IPC: G01N21/78
Filed: 1988-05-27
Abstract: The present invention provides a sensor, preferably an electrochemical sensor, for detecting acidic gases, e.g. carbon dioxide. The electrochemical sensor has a sensing electrode (20, 22), a counter electrode (37) and a body of electrolyte containing a complex, e.g. copper(II) bis(propanediamine), which has one or more ligands that is displaceable by the presence of the acidic gas in the electrolyte to form a modified complex which can be electrochemically reacted at the sensing electrode at a potential at which the unmodified complex is unreactive. The acidic gas diffuses into the electrolyte through a porous membrane. The modified complex can also be detected colorimetrically because it absorbs light at a different wavelength to the unmodified complex.

Title: Method for reducing friction between relatively slideable components using metal overbased colloidal disperse systems
Inventor: VINCI JAMES NOEL
IPC: C10N10/04
Filed: 1990-04-19
Abstract: A method and compositions for reducing friction between relatively slideable components is described comprising applying to a slideably engaging surface of the slideable components a lubricating amount of at least one Newtonian, or non-Newtonian, metal overbased salt of a carboxylic acid wherein the metal is selected from the group consisting of lithium, calcium, sodium, barium, magnesium, and mixtures thereof, and the carboxylic acid comprises at least one linear unsaturated hydrocarbon group containing from about 8 to about 50 carbon atoms. The types of slideable components contemplated include flat bearings, rotating bearings, lead screws and nuts, gears, hydraulic systems, and pneumatic devices.

Granted: 2005-09-14
Abstract: A vehicle travel control apparatus makes an own vehicle automatically follow a vehicle in front by setting a target acceleration/deceleration G 0 using travel data expressing behavior of the vehicle, travel environment, driving operations and others. Here, during vehicle travel based on driver control, multiple travel data are sampled a predetermined number of times to perform multiple regression analysis on that sampled data. Preference data expressing preferences of the driver (multiple regression coefficients) are thereby obtained, and target acceleration/deceleration computation data are updated using these multiple regression coefficients. As a result, it is possible to control the behavior of the vehicle in accordance with preferences of the driver during automatic following control execution.
