Title: Method of and apparatus for treating fluids to alter their physical characteristics
Inventor: SHROFF DAVID N
IPC: C02F1/48
Filed: 1995-01-27
Abstract: Method and apparatus for altering the physical characteristics ofliquids and gases. The fluid is pumped into an elongated cylindrical chamber whose elongated wall (12) contains a multiplicity of spaced apart cylindrical holes (12A) under sufficient pressure to cause the fluid to exit from the cylindrical holes (12A) as jets having an exit velocity of at least 0.025 feet (.0076 m) per second. The jets of fluid exit from the cylindrical holes (12A) into an annular chamber (15) surrounding the elongated cylindrical chamber and having a common axis as the elongated cylindrical chamber. The entire inner surface of the annular chamber (15) is coated with an alloy of copper and nickel. The jets of fluid bombard the surfaces of the annular chamber to induce the copper-nickel alloy to give up electrons. The freed electrons combine with a significant number of molecules of the fluid to thereby alter the physical characteristics of the entire body of fluid.

Abstract: A mechanical duty rubber diaphragm for use as a high speed dynamic seal is provided which overcomes the bending fatigue failure common to conventional rubber diaphragms. A comparatively thick rubber diaphragm of hollow conical shape is employed which has metal hoops bonded to outer and inner diameters.  Upon the diaphragm being reciprocated along a central axis the hoops hold the rubber in true shear without bending and thus preclude the propagation of unavoidable minute cracks or discontinuities in the rubber into large tears, the common fatigue failure mode in rubber diaphragms.

Patent CA-2244366-A1 (CA)
Inventor: STEER DAVID G
IPC: H04W36/24
Filed: 1998-07-29
Abstract: An improved method of selecting a basestation for handoff within a mobile communications system is provided.  In addition to signal quality information, a basestation is selected based upon velocity parameter information which indicates which basestation or basestations that the mobile station is moving towards or away from.  A basestation is selected such that it has an acceptable signal quality, and such that it is a basestation which the mobile station is moving generally towards.  In this manner, spurious handoffs which might happen at an intersection for example, are avoided.  The velocity parameter might be an absolute velocity measurement, or a Doppler shift measurement which indicates only the component of the velocity in the direction of each basestation.  A convenient way to compute the Doppler shift measurement in a multipath environment is to examine the rate of change of the phase of a lowest delay equalization weight.
