Abstract: A hose coupling assembly utilizes first and second hose collar halves interacting with a barbed connector for mounting to a PVC spiral hose with screws. The collar halves are identical and may be molded from flexible plastic material for ease of attachment to the spiral hose.
Abstract: A method of conditioning a fluid flow from a first area to a second area downstream from the first area. The flow coming from the first area is directed in a longitudinal direction. The cross-section of flow is increased, and the flow is split by means of an impact surface substantially perpendicularly to the longitudinal flow direction. The split is caused to flow symmetrically relative to the longitudinal flow direction over a predetermined distance from the splitting to the second area without reducing the rate. The split flow is accelerated over at least a portion of said predetermined distance. The flow is mixed to achieve a conditioned fluid flow in the second area.
Abstract: The system provides a way to use a single RF channel in a cellular, RF meter reading system. In order to avoid adjacent cell concentrator interference while reducing the overall time required to perform repetitive tasks such as meter reading and performing load survey reads, the system has each of the concentrators send out a general command to all of the meter interface units ("MIUs") in its cell, and the MIUs then each send back their data in turn. In order to accomplish that result, the MIUs in each cell are preprogrammed to transmit a preset time period (different for each MIU in a particular cell) following receipt of the general command requesting data.The AMR reporting sequence in each cell is assigned based upon the physical distance of an MIU which is being assigned an AMR reporting sequence number from the MIU which had been assigned the prior AMR reporting sequence number.
