Abstract: An apparatus that restricts or disables electronic device functionality based on vehicle status data received from the on-board computer (“OBD”) of a public service vehicle. In some embodiments, the vehicle status data is accessed from the OBD through an assembly line diagnostic link (“ALDL”) connector, which eliminates any need for modification of the vehicle during installation. If the software determines the vehicle status data is outside a preset range, which could be customized on a case-by-case basis, the on-board computer of the vehicle could be restricted or disabled until the vehicle status data returns to within the preset range.

Abstract: A cyclone assembly has a modular body formed from a plurality of releasably coupled body portions. A chamber is defined by and extends between the ends of the modular body. A vortex finder is releasably coupled to a first end of the modular body, and an apex is releasably coupled to the second (opposite) end of the body. The vortex finder, apex and individual body portions may be individually repaired or replaced, as needed.

Abstract: This invention is directed to a method and an apparatus to heat certain particles. These certain particles are heated to make them more desirable. In the heating of these particles, it is often desirable to expand the particles to make a light-weight aggregate. The light-weight aggregate may be used in making a building material or the like. In carrying out the process of heating these particles, there is used air for combustion of the combustible fuel and only a mimimum of air for carrying of the particles or expansion of the particles.

Abstract: A trolley rail section includes an elongated housing wherein a conductor junction assembly is retained by virtue of its connection to an elongated conductor within the same housing and with the cooperation of the conductor of an adjacent connected trolley rail section such that the unitary conductor and junction assembly may be assembled into or disassembled from their housing according to a method of assembly when the respective trolley rail section is disconnected from other trolley rail sections.

Abstract: An overhead metal trolley rail has a head for supporting it, separated by a vertical web from a foot that projects from opposite sides of the web and has flat upper contact surfaces. Slidable along the rail is a trolley shoe formed from a block of electrical conducting material, the upper portion of which has a longitudinal trough in it receiving the foot of the rail. The lower portion of the trough is spaced from the rail, but the upper portion of the trough has longitudinal flanges projecting inwardly toward each other above the foot of the rail. The flanges have flat lower contact surfaces engaging flat against the flat contact surfaces of the rail and supporting the shoe, from which a power take-off wire extends.

Abstract: A trolley rail section is formed from a tubular housing that has a front side provided with laterally spaced slots extending lengthwise of the rail, and a partition wall extending across the inside of the housing and closing the inner sides of the slots, the side walls of which are provided with grooves receiving electrical conductor bars. The partition wall and the back of the housing have opposed openings therethrough, with each pair of openings communicating with a different one of the slots. Disposed in each partition wall opening and straddling the adjoining conductor bar is a U-shape metal clip with inturned free front edges overlapping the front of the bar. Disposed in the clip behind the bar is a metal plate that is pressed against the bar by set screws threaded in the back of the clip. A rigid metal conductor connection extends loosely through an opening in the back of the clip and is rigidly secured to the plate and provided with an abutment spaced rearwardly from the clip.

Abstract: A trolley rail housing provided with a plurality of parallel open-bottom slots extending lengthwise thereof has an electric conductor mounted up in each slot, with an end portion of the housing offset upwardly and connected by a downwardly inclined portion to the rest of the housing. An electrical pick-up unit adapted to be carried by a vehicle includes a plurality of collectors mounted for vertical and lateral movement, with spring means urging the collectors upwardly. This unit also includes a pair of laterally spaced guide members disposed above the collectors and movable laterally with them and adapted to engage the opposite sides of the rail housing when the pickup unit, separated from the housing, is moved toward its offset end.

Abstract: A trolley rail is formed from a plurality of aligned tubular housings, each of which has a front side provided with laterally spaced slots extending lengthwise of the rail, and a partition wall extending across the inside of the housing and closing the inner sides of the slots, the side walls of which are provided with grooves receiving electrical conductor bars. The partition wall and the back of the housing have pairs of aligned openings therethrough, with each pair of openings connecting with a different one of the slots. Disposed in the partition wall openings and straddling the adjoining conductor bars are U-shape metal clips with inturned free front edges in front of the bars. The clips are provided with springs or screws pressing conductor bars therein against the inturned edges of the clips.

Abstract: Apparatus is supported by one end of a line of rails for feeding metal bars from a coil lengthwise into parallel longitudinal slots in the rails to form continuous straight electrical conductors. The feeding apparatus includes a plurality of staggered straightening rolls for straightening the conductor bar as it is pulled from the reel for feeding it into the slot in line with the apparatus, the apparatus being adjustable transversely of the rails to locate it in line with the different slots.

Abstract: An extruded plastic housing of indefinite length contains an electrical conductor bar in a slot extending lengthwise of the housing. The bar is retained in the slot by a pair of ribs integral with the side walls of the slot and extending lengthwise thereof and projecting toward each other. The width of the bar is greater than the space between the ribs, but the housing is so formed that in assembling it and the bar the distance between the ribs can be increased temporarily by pressure of the bar against them to permit it to be moved rearwardly past the ribs, whereby the bar can be inserted from the front or outer side of the slot, thus permitting the use of a single conductor bar regardless of the number of housing units that may be disposed end to end to form the housing.
