Granted: 2003-02-04
Abstract: Abrasion-wear  resistant  thermal  sprayed  stainless  steel based  coatings  are  disclosed,  particularly  arc  sprayed stainless  steel coatings  containing  titanium  diboride crystals which impart hardness to the soft stainless steel matrix and enhance their resistance to hard abrasive media. There is also disclosed a process for making core wires composed of stainless steel sheaths and cores composed of a mixture of titanium diboride,  stainless steel and certain additives.    During  the  thermal  spraying  operation,  the stainless steel sheath and the core material melt to form a composite  coating  containing  fine  hard  titanium  boride crystals dispersed within stainless steel.  The arc sprayed stainless  steel  based  coatings  are  more  resistant  to abrasion wear than solid pieces of type 304 stainless steel and  other  arc-sprayed  stainless  steel-based  coatings available on the market.  Although reference is made mainly to the arc spraying process,  the core wires are suitable for other thermal spraying processes that use wires as the feed material,    for  instance  combustion  and  arc-plasma spraying and weld overlay surfacing techniques.

Abstract: A single-phase method for quantitatively measuring the anionic surfacatant content of an aqueous machining fluid is provided. The method is carried out  at a pH value of from about 1.5 to about 3.0 and from about 9.5 to about 10. 6 and involves the addition of an excess of a standardized aqueous solution of  1,3-didecyl-2-methylimidazolium chloride to the sample of aqueous machining fluid and then back titrating the excess 1,3-didecyl-2-methylimidazolium chloride with a standardized aqueous solution of polyvinylsulfuric acid potassium salt in the presence of toluidine blue indicator. Values of the amount of 1,3-didecyl-2-methylimidazolium chloride amount corresponding to anionic surfacatant concentration are produced by conducting the method usin g a series of stantard aqueous solutions containing anionic surfactant at know n concentrations. These values are used to quantitatively determine the anioni c surfactant content of a sample of aqueous machining fluid of unknown anionic  surfactant concentration from measured values of 1,3-didecyl-2- methylimidazolium chloride obtained according to the method using the sample .

Abstract: A brake controller for use in a tow vehicle to control the application of towed vehicle brakes. The brake controller is responsive to movement of the tow vehicle brake pedal to send electronic brake control signals to the towed vehicle brakes, actuating the brakes in proportion to the movement of the brake pedal. An optical coupler senses movement of the brake pedal by a graduated increase in transmitted light, or by counting marks associated with a spring-tensioned cable or chain secured between the tow vehicle firewall and the brake pedal arm. A microcontroller is incorporated into the brake controller to adjust the proportionality of the brake actuation in response to operator gain settings, and to allow for manual actuation of the towed vehicle brakes.

IPC: G02B27/28
Filed: 1998-12-22
Granted: 2005-02-15
Abstract: A method and circuit is provided for more efficiently coupling light between two optical waveguides such as optical fibres. When the two waveguides are coupled to spaced apart collimating lenses such as GRIN lenses, the beam propagating between the spaced part lenses may be shifted. In this instance light can more efficiently be coupled out of the output optical fibre if it is angled with respect to the optical axis of the GRIN lens to which it is coupled. This invention provides an output fibre that is non-parallel with the optical axis of the lens it is coupled thereto.
