Patent CA-2219109-A1 (CA)
Inventor: KESHAVIAH PRAKASH
IPC: A61M1/16
Filed: 1997-04-24
Abstract: An improved on-line, real time hemodialysis monitoring system (10) for hemodialysis treatment, quantitates the rate and amount of a constituent, such as urea, removed during the hemodialysis treating by measuring the constituent concentrations as a function of time in the spent dialysate effluent from a hemodialysis machine (120). A quantity of the spent dialysate effluent is removed from the dialysate effluent waste line periodically for testing. A urea concentration time profile can be analyzed to determine the urea removal, KT/V, URR, SRI, and normalized protein catabolic rate (nPCR) indices. The hemodialysis monitoring system (10) preferably can obtain a dialysate sample equilibrated with the blood prior to the start of a hemodialysis treatment. In a further aspect, the hemodialysis monitoring system (10) includes a device for conducting two-pool analysis for taking into account the constituent concentration differences in the extracellular and intracellular spaces (92, 94) in the hemodialysis patient during the hemodialysis treatment to determine the intercompartmental transfer coefficient K, of a patient, which allows more precise adjustment of the hemodialysis prescription for the patient.

Title: Agricultural sprayer having spray shaping nozzles connected to low pressure air spray
Inventor: JONASSON KEVIN A
IPC: B05B7/08
Filed: 1996-06-04
Abstract: An atomizing nozzle (40) primarily designed for agricultural spraying has a narrow and controlled droplet size distribution and the ability to shape the spray into a solid cone or fan for evenly applying the spray to the crops. The nozzle (40) is able to operate at low air delivery pressures, in the order of 10 to 30 in. of water column. A central air delivery bore (44) communicates with an air manifold within a boom (12). Near the exit plane (46) of the throat there is provided an inlet conduit (56) connected to the liquid to be sprayed, the conduit (56) being at right angles to the bore axis. An outlet nozzle (58) from the conduit (56) is positioned on the bore axis and has its exit plane (60) upstream of the exit plane (46) of the bore (44) so that atomization of the liquid will take place within the central bore (44) between the two exit planes (46, 60). A pair of shaping nozzles (66) are connected to secondary bores (68) that in turn communicate with the manifold (12). The shaping nozzles (66) are directed orthogonally to the central bore axis and to the inlet conduit (56) and are located downstream of the exit plane (46) of the central bore (44). The jets issuing from the shaping nozzles (66) shape the cone-shaped spray into a generally fan-shaped configuration. Because the shaping jets are always at the same pressure as the atomization air the dispersion of the droplets exiting the nozzle (40) will be consistent and the spray pattern will be constant over the operating pressure range of the apparatus.

Patent CA-2237905-A1 (CA)
Title: Spray nozzle
Inventor: TSCHUMI OTTO
IPC: B05B7/12
Filed: 1997-09-24
Abstract: A spray nozzle of the type adapted to feed a liquid to a material being sprayed therefrom comprises a tubular spray conduit around which is arranged an annular feed port, this feed port being closed in a liquid-tight manner by resilient material openable by liquid pressure and whose degree of opening, and therefore the quantity of liquid fed to the material, rises linearly with increasing liquid pressure.     Preferably, the resilient material is provided by a membrane ring (7) which is a flat ring with inwardly-tapering radial ridges (8b) raised thereon, the gaps between the ridges being filled with an elastomeric material, such that a series of resilient segments (9) is created. Under liquid pressure, the segments are compressed equally, giving a nearly completely annular flow of liquid into the material. The nozzle is particularly useful for the spraying of concrete, especially by the dry method.

Title: Method and apparatus for detecting aberrant motor operation in a plastics processing machine
Inventor: O'BRYAN JAMES E
IPC: B29C45/76
Filed: 1998-10-16
Abstract: A method and apparatus for detecting an aberrant velocity of a motor used to drive an element in a plastics processing machine, such as an injection molding machine, for example. The velocity of the motor is detected by a first sensor and a machine parameter associated with the machine operation is provided. A velocity limit is determined based upon the machine parameter and an error signal is generated when the motor velocity exceeds the velocity limit by more than a predetermined tolerance value. Preferably, the machine parameter comprises the position of the element driven by the motor, which is sensed by a sensor, such as a linear displacement transducer. The velocity limit can be based upon this measured element position as well as data entered for the particular machine, such as a minimum element position, a maximum element position, and a maximum motor velocity, such that a desired motor operating envelope is defined. Also, the motor velocity command is preferably set equal to the velocity limit when it exceeds the limit. In another embodiment, the machine parameter comprises a motor velocity command for controlling the velocity of the motor. The velocity command is compared to the previous velocity command and the velocity limit is set equal to the velocity command when it exceeds the previous command.
