    摘要： An automated meter reading system is provided. The system includes a host server interfaced to a plurality of nodes where each node communicates with a number of utility meters. The system selects a group of noninterfering nodes and uses an RF broadcast from the host server to initiate the reading of meters and the uploading of meter data provided by those meters to the nodes and, ultimately, to the host server. The system also has a number of gateways that communicate with a plurality of nodes, grouped to form sets of noninterfering gateways. In this embodiment, the system selects a set of noninterfering gateways and uses an RF broadcast from the host server to initiate the reading of meters and the uploading of meter data provided by those meters to the nodes and, ultimately, through the gateways to the host server. A method for using an outbound RF channel to automatically read meters is also provided.

    摘要： A rotary feed structure for a gunite-conveying machine includes a polymeric body to resist sticking of gunite even if the latter includes silica fume, and even if it has set. The body has chambers in a circle. Preferably the body is urethane, self-bonded to a Ni-hard wear plate to eliminate radial leakage, and the mounting, (typically holes for studs), at least in part, is integral with the plate. A metal axial spacer is preferably next to the plate, but only within the innermost radius of chambers and with a sizable wall thickness. The body is preferably a feed-bowl type, with chambers formed as generally U-shaped pockets. A gunite machine using the polymeric feed structure also has a hopper, delivery tube, support and rotation of the feed structure, compressed-air for expelling the particulate material from the chambers into the tube, and provision for transporting the hopper, tube, body, and other apparatus. Chambers are selectively sealed to the expelling device and delivery tube. Dust emission is controlled by a short fill at the expulsion end of each chamber, and selective venting of residual pressure through the air-inlet end. Remaining dust, collected by a dry bag or atomizer nozzle, is preferably recycled to the bowl. New materials and procedures are used for fabricating the polymeric body.

    摘要： A slip ring assembly having a rotatable chamber including a shaft rotatably mounted therein. A plurality of slip rings are provided within a ring section of the rotatable chamber and are mounted to the shaft for rotation therewith. The plurality of slip rings for a group of preselected pairs of slip rings. An electrical conductor is connected to each slip ring with each electrical conductor being twisted to at least one adjacent electrical conductor through a central core in the shaft to thereby cancel alternating current due to self-generated voltages. The slip ring assembly also includes a brush assembly having at least one brush support associated with each slip ring with each brush support having brushes extending therefrom in contact with its corresponding slip ring at at least two brush contacts. The brush contacts for each slip are orientated approximately 180 degrees apart. Furthermore, brush contacts for each preselected pair of adjacent slip rings are orientated at an offset of approximately 90 degrees.
