Title: Method and apparatus for converting pressurized low continuous flow to high flow in pulses
Inventor: RUTTENBERG GIDEON
IPC: B05C11/10
Filed: 1990-09-10
Granted: 2004-07-27
Abstract: This invention relates to a device and method for converting low continuous flow to a high intermittent and pulsating flow arid is especially adapted for operating sprinklers, showerheads etc. at low flow. Fluid is introduced at a controlled low flow, such as by the use of a dripper (5, 24) in a supply line (7), into a container (1, 22) having expandable chamber (2). The outflow of li-quid from the chamber (2) is restricted until pressure created by the introduction of the liquid is sufficient to force the valve to open, and in response to a resistance to the flow, the fluid intermittently ejects at a higher flow. This is achieved by utilizing a preset pressure responsive valve (8, 28), designed for quick response, to create a water hammer effect. The invention describes pulsating valves and other devices operating in response to deformation created in elastic membranes in response to pressure changes.

Abstract: An improved conductivity based servo-proportioning sys-tem (10, 40) for hemodialysis machines. The servo-proportioning system calculates the actual conductivity contributions of the indi-vidual chemical components of the concentrate being utilized, to determine the conductivity set points. An Acidified and Bicarb operation is being performed, then the servo-proportioning sys-tem calculates a conductivity set point at both an intermediate and final stage of the servo-proportioning system. If only acetate is being performed, then only the acetate individual chemical components are calculated. If the Na and/or Bicarb concentra-tions are to be varied, then the conductivity is calculated for the changed Na and/or Bicarb concentrations.

Abstract: A method and apparatus for reducing correlated errors in subband coding systems with quantizers is disclosed. A subband coding system comprises aplurality of subband analysis filters to divide the frequency spectrum of the input signal into subbands, individual subband quantizers for coding each subband by apreselected number of quantization levels, corresponding subband decoders and subband synthesis filters. The transfer function of each of the subband synthesis filters is advantageously determined based on the transfer functions of the subband analysis filters as well as on the characteristic of the quantizer used to code the corresponding subband. Specifically, the synthesis filter transfer functions may be based on a perfect reconstruction filter bank or a quadrature mirror filter bank, as well as on the gain factors of a gain plus additive noise linear model for the Lloyd-Max quantizers used to code the corresponding subbands. That portion of the error between the input signal and the replica signal as reconstructed by the system which is correlated to the input signal may be advantageously reduced or eliminated, irrespective of that portion of the error which is uncorrelated to the input signal. Thus, the total error in a final signal may be advantageously reduced by the subsequent application of prior art techniques for the reduction of random, uncorrelated noise.

Title: Improved method and apparatus for calculating flow rates through a pumping station
Inventor: JORRITSMA JOHANNES N
IPC: G01F13/00
Filed: 1994-10-14
Granted: 2004-08-03
Abstract: A method and apparatus for determining liquid flow through a system including a container from which liquid is pumped out by one or more pumps, the pumping rate for all combinations of pumps being known and stored in a memory. When pumping is off, the liquid surface rises from a lower to an upper limit level. When the surface reaches the upper limit level, the pumping phase begins. When the surface reaches the lower level, the pumping is stopped and the cycle is repeated. If only one pump is required, the inflow rates prior to and just after the pump cycle are averaged. This average flow rate is multiplied by the pump time and added to the totalizer. Then the container volume is also added, following which the outflow rate (pump rate) is calculated by using the previously established average inflow rate (total volume divided by pumptime plus the average inflow rate). This value can be stored in the addressable memory.  If a plurality of pumps is required to make the liquid level drop, the liquid volume pumped during the pumping phase is calculated from information in the memory to determine the stored volume pumping rate for the particular operating pumps, and multiplying such stored rate by the duration of the pumping phase.  The result is then added to the totalizer.

Abstract: Methods are disclosed for predicting RF propagation within a structure such as abuilding, characterized by the following steps. A reference transmitter location and a plurality of reference receiver locations are selected. For each reference receiver location, RF propagation pathways are determined with respect to the reference transmitterlocation. The RF propagation pathways include a direct path joining the reference transmitter location to a given reference receiver location across a straight-line path, as well as one or more reflection paths joining the reference transmitter location to a given reference receiver location via reflections from one or more reflective surfaces. One or more propagation pathways may pass through an RF obstacle, such as, for example, a lossy dielectric material. Each reflective surface and RF obstacle is associated with a reflection coefficient and a transmission coefficient. These coefficients are computed for each object and surface from a multilayer dielectric model, maintaining angle and polarization dependencies. For each propagation pathway, a propagation componentconsisting of the propagation loss relative to free-space propagation is calculated as the product of the magnitude squared of the reflection and transmission coefficients. The local mean of received RF power at each of the reference receiver locations is calculated as the scalar sum of the powers of all the propagation pathway components reaching the specified location.

Abstract: An  improved  surge  arrestor for RF devices  includes  a bifilar conductor pair wound around a ferrite core wherein one end of each conductor is grounded.  The energy of RF signals input to the surge arrestor from an RF transmission line is transferred from the primary windings to the secondary windings through the magnetic coupling.  When an electrical transient or fault causes a surge on the input or primary side of the surge arrestor,  the core becomes  saturated,  thereby limiting the amount of energy transferred to the secondary windings and the RF device.  This effectively isolates the secondary side of the surge arrestor from the damaging surge in voltage and prevents the  secondary side from conducting the surge to electronic components within the RF device.
