Systems and methods are provided for worker protection. A safety vest may be configured to support worker protection receiver function in worker protection systems. Components used in conjunction with the receiver functions may be integrated into the safety vest. The components may include one or more antennas, radio receiver (or transceiver) circuitry, integrated power supply source, indication components, and acknowledgement components. The safety vest may generate safety alerts in response to receiving signals from peer transmitter devices in the worker protection systems.

Systems, methods, routines and/or techniques for a crossing gate tip sensor are described. According to one or more embodiments of the present disclosure, a crossing gate tip sensor may be attached to or incorporated into a gate arm of a crossing gate. The crossing gate tip sensor may accurately detect the orientation (among other things) of the gate arm. In some embodiments, a crossing gate tip sensor may include a tilt sensor that includes one or more accelerometers. In some embodiments, a crossing gate tip sensor may include a microcontroller and/or a wireless communication unit.

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.

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.

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.

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.

A method is now utilized for stripping costly electrocatalytic coatings from valve metal substrates while maintaining excellent integrity of the substrate metal. The removed metal may also be conveniently recovered. A molten salt bath of alkali metal hydroxide and alkali metal salt of an oxidizing agent is employed. Careful electrode to bath contact times and bath temperatures are observed. Additionally, a dilute mineral acid rinse and water rinse, with scrubbing in one of the rinses follows such molten salt bath contact for the electrode. Solids recovered from the rinses are combined.

A portable traction device incorporating a simple and quickly-attachable frame adapted to be positioned on the frame of a patient transport cot for the application of traction force to a patient during transport. The traction device includes a base frame or U-shaped bracket member which fits around the frame of a cot and includes flanges thereon to mount the bracket member on either end of a transport cot. The bracket member has suitable guide sleeves therein and a U-shaped pulley bar is adjustably positioned in the guide sleeves of the bracket member. Adjustably positioned pulleys are mounted on the pulley bar such that through the use of appropriate slings, traction force may be directed to the limbs, pelvis or cervical neck regions of the patient being transported to provide a traction force to the patient during transport.

摘要:
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.
