A plurality of sensors, each generating distinct signals in response to the passage of leading and trailing edges of car wheels, are positioned along the rail at a height above the rail to detect the passage of a selected chord on the wheel tread. The distances between initial sensors and the final unit equal the various selected chord lengths on conventional sized wheels. When one of the initial sensors detects the passage of the trailing edge of the wheel at the chord level simultaneously with the detection of the leading edge of that wheel by the last unit, the output signals are applied to a logic circuit, which registers a wheel of corresponding diameter. Additional sensors placed immediately adjacent the final sensor provide measurement of actual wheel diameters slightly less than the standard sizes due to wheel wear. When the sensors detect a gap in the tread chord, as a worn wheel passes, greater than a predetermined length for each diameter wheel, an indication is provided of a worn wheel requiring replacement. A second set of sensors positioned on the other side of the rail measures the flange height to also indicate wheel wear.

This disclosure relates to a predictor for determining the coefficient of friction existing between the rotating wheels of moving railway vehicles and the brake shoes of a pair of brake elements prior to the humping operation in a classification. One of the brake elements is slidably mounted to move longitudinally relative to the track rail when engaged by the rotating wheels of the railway vehicle. The kinetic energy or force imparted to the slidable brake element is transposed in fluid pressure by a pressurized responsive transducer. The fluid pressure is sensed by a measuring device which activates an alarm when the wheels of the railway vehicle are dirty or contaminated by unctuous material to permit the vehicle to be diverted to a sidetrack for special handling.

Apparatus disposed in parallel relation to rails of a railway track section ahead or in advance of a railroad car retarder for applying a solid type lubricant to those areas of the car wheels frictionally contacted by the retarder and thereby suppressing excessive noise or squealing during retarding action.

A holder molded of suitable elastomeric material cradles a plug-in relay in operating position, with access openings for calibration adjustments, visual inspection of contacts, and plug coupling of connecting leads. The holder is mounted to a mounting plate and/or the shelf by bolts inserted into cylindrical openings in the bottom of the holder and through a web or diaphragm molded as an integral part of the holder. A spacer tube placed over each bolt spaces the holder a selected distance above the mounting plate. Washer disks of the elastomeric material are placed on both sides of the diaphragm and a lock nut secured onto the bolt to fasten the holder in place. The diaphragms, disks, and spacers combine to provide vibration damping and shock isolation for the relay.

An electrochemical cell for use in gas detection includes a cell body having an electrolyte cavity and a separate sensor cavity. The sensor cavity holds stacked sensor elements including a counter electrode, electrolyte mat, reference electrode and sensing electrode. A wick draws the electrolyte from the electrolyte cavity to the electrolyte mat. The sensing electrode closes off the sensor cavity and seals the counter and reference electrodes therein. The only gas which contacts the counter and reference electrodes is that which passes through the sensing electrode or is generated by the counter electrode and becomes dissolved in the electrolyte.

An electrochemical sensor for detecting gas includes stacked reference, counter and sensing electrodes within a body and having a quantity of a liquid electrolyte in an electrolyte chamber therein. A support is provided for holding the electrodes and mats in contact with each other and at an inner end of a cavity within the sensor. A gas passage, such as a diffusion limiter, is provided through the sensor body and permits gas to reach the sensing electrode. The reference electrode is formed in a wraparound structure, with the reference electrode provided with a plurality of integral extensions which extend around the support and the counter electrode and into contact with the liquid electrolyte, thereby providing a large reference electrode fitted into a small body.

An optical instrument for locating the focal point of a smooth surface concave reflector of a signal lamp unit. The optical instrument includes a cylindrical metallic base member for insertion into the electrical socket of a light bulb. A translucent sighting target member is carried by the base member and includes a reticle for focusing in a distant image whereby the filament of a light bulb will be located at the focal point of the concave reflector for maximizing the illuminative efficiency of the signal lamp unit.

This disclosure relates to a railway trackway having a pair of running rails and including a plurality of vibrational dampening mechanisms disposed at selected intervals along the running rails of the trackway. Each of the vibrational dampening mechanisms includes a support assembly and a biased wheel engaging assembly for engaging the passing wheels of the railway vehicles for dissipating the vibrational energy imparted to the vehicle wheels thereby preventing the production of wheel squealing or screeching noises.
