Patent CA-2112089-A1 (CA)
Inventor: LEANES JAMES A
IPC: G01R21/10
Filed: 1993-12-21
Abstract: A wideband detector having a substantially flat response is made by using the sigval at the isolation port of a coupler. As the response or transfer characteristic at the isolation port is substantially linear, a matching network having the inverse of opposite transfer characteristic with respect to frequency may be connected to the coupler. The addition of the matching network transfer characteristic to the transfer characteristic of the coupler in the isolation port produces a superposition. The matching network transfer characteristic compensates for the linear varying transfer characteristic at the coupler isolation port to produce a substantially flat output of the matching network. The detector connected to the matching network output will then produce a detector signal which is substantially flat over the frequency range of the bandspread of interest.

Title: Water decontaminating device
Inventor: SZABO LOUIS
IPC: A61L2/10
Filed: 1994-09-26
Abstract: A dual mode sterilizing apparatus is provided use in a system for sterilizing a fluid, to simultaneously generate ozone and expose  the  fluid  to  ionizing  radiation.    The  apparatus comprises water and  air chambers for the circulation of contaminated water and an air supply, respectively.  A UV lamp or other source of ionizing radiation is positioned to expose the water within the water and air chambers to  ionizing radiation.  An air supply conduit has a first part positioned within the water chamber, wherein the air is cooled by the relatively lower temperature of the water, and a second part positioned adjacent the UV lamp, where the air is slightly warmed by the proximity of the lamp.   The cooling effect within the first part of the conduit causes moisture within the air to condense on the walls of the conduit.  Within the second part of the conduit, the warming effect of the lamp causes the relative humidity of the air to drop, following which the air supply is vented into the air chamber for exposure  to  ionizing  radiation.    Following  exposure  to radiation from the lamp, the ozonated air is withdrawn through an outlet vent, for combination with and purification of the water flowing through the system.

IPC: B63B29/00
Filed: 1994-10-05
Abstract: In a personal recreational watercraft, an improvement resides in a suspension mechanism, which permits greater maneuverability and stability, and reduces driver fatigue.  To overcome the strong forces, a suspension system is employed which permits up and down vertical movement, while resisting lateral movement and torsional forces, thus the suspension apparatus reduces shock effects caused by choppy or rough water.          In addition to driver comfort, the suspension system provides less shock to the drivetrain.  In choppy water, the hull moves in a less erratic manner and the jet pump maintains greater contact with the water.
