  • Publication number: 20120296562
    Abstract: A collision avoidance system (CAS) is described that includes one or more sensor technologies, including, for example, an Ultra Wideband (UWB) sensing technology. The collision avoidance system is designed to reliably track the location and speed of vehicles and the distance between vehicles over a wide variety of track and terrain. The collision avoidance system may utilize information from a variety of sensor technologies to determine whether one or more vehicles violate speed and/or separation criteria, and may generate a warning.

  • Publication number: 20120138752
    Abstract: A rail line sensing and safety system adapted to reliably sense the presence, and optionally the direction and speed, of vehicles traveling on a rail line, and when a vehicle is sensed, to indicate whether a safety device, such as crossing gates, lights, bells, etc., should be activated. The system comprises at least one detection module typically mounted on a rail, at least one remote module typically located near a detection module, and at least one control module typically located near a safety device. In operation, a detection module senses a vehicle traveling on a rail line and sends signals to a remote module. The remote module then processes signals received from the detection module and transmits signals to the control module. The control module then directs, either directly or indirectly as a backup or supplement to an existing sensing and safety system, whether a safety device should be activated.

  • Patent number: 8142898
    Abstract: The present invention relates to an electrocatalytic coating and an electrode having the coating thereon, wherein the coating is a mixed metal oxide coating, preferably ruthenium, titanium and tin or antimony oxides. The coating uses water as a solvent that provides for a smoother surface than alcohol based solvents. The electrocatalytic coating can be used especially as an anode component of an electrolysis cell and in particular a cell for the electrolysis of aqueous chlor-alkali solutions.

  • Publication number: 20110174628
    Abstract: A cathodic member for electrochemical cells used in hypochlorite production comprises a zirconium plate coated with a zirconium oxide layer, which is particularly suitable for minimising the decomposition of the hypochlorite product while ensuring a prolonged lifetime. The coated zirconium plate can be used as the cathodic plate in a monopolar cell, or can be welded to a titanium plate for use in a bipolar configuration.

  • Patent number: 6309523
    Abstract: An electrode is disclosed having a coating on part of the electrode, e.g., a front face, comprising the oxides of tin, antimony, at least one platinum group metal and at least one valve metal. Another part of the electrode, such as a back face, has a coating comprising the oxides of at least one valve metal and at least one platinum group metal. The electrode can be generally plate-shaped and most desirably has at least one chamfered corner. The electrode is particularly useful in a cell wherein brine electrolyte is electrolyzed to prepare a disinfectant solution containing hypochlorite. The disinfectant solution can be especially serviceable, such as in maritime application, for treating water, e.g., freshwater as represented by desalinated water.

  • Patent number: 6071570
    Abstract: A method of preparing electrodes is now described, which electrodes have enhanced adhesion of subsequently applied coatings combined with excellent coating service life. In the method, a substrate metal, such as a valve metal as represented by titanium, is provided with a highly desirable rough surface characteristic for subsequent coating application. This can be achieved by various operations including etching to ensure a roughened surface morphology. In subsequent operations, a barrier layer is provided on the surface of enhanced morphology. This may be achieved by operations including heating, as well as including thermal decomposition of a layer precursor. Subsequent coatings provide enhanced lifetime even in the most rugged commercial environments.

  • Patent number: 5923032
    Abstract: An improved optical encoder with a simplified construction for reliable component alignment and enhanced resolution is disclosed. The encoder includes a housing with locating points, such as studs and shelves, integrally formed on inner surfaces of the housing. The locating points reliably fix the X, Y and Z axis orientation between a light detector and light source assembly. The light source assembly preferably comprises two light detectors on a single board to increase resolution. Additional features of the invention include a sealed housing and a code wheel having two concentric tracks of transmissive slots that are circumferentially offset from each other and an external cable strain relief assembly.

  • Patent number: 5545262
    Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable surface characteristic for subsequent coating application. This can be initiated by selection of a metal of desirable metallurgy and heat history, including prior heat treatment to provide surface grain boundaries which may be most readily etched. In subsequent etching operation, the surface is made to exhibit well defined, three dimensional grains with deep grain boundaries. Subsequently applied coatings, by penetrating into the etched intergranular valleys, are desirably locked onto the metal substrate surface and provide enhanced lifetime even in rugged commercial environments.

  • Patent number: 5324407
    Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable surface characteristic for subsequent coating application. This can be achieved by a plasma sprayed coating of well defined surface morphology, the plasma spraying being with one or more metals usually valve metals. The metal of the coating may be the same or different from the metal of the substrate. Subsequently applied coatings, by penetrating into the coating of well defined surface morphology, and desirably locked onto the resulting metal article an provide enhanced lifetime even in rugged commercial environments.
