Patent CA-2168191-A1 (CA)
Title: Dishwasher with venturi drain
Inventor: KIRKLAND DANIEL R
IPC: A47L15/42
Filed: 1996-01-26
Abstract: A dishwasher sump is divided into a collection chamber and a pump chamber by a filter.  Food particles collect in the collection chamber while filtered wash liquid collects in the pump chamber.  The filtered wash liquid is recycled and sprayed on objects in the dishwasher.  A venturi jet pump has a suction gap located in the collection chamber and an outlet connected to a drain.  At the end of a wash cycle, the wash liquid is pumped through the jet pump thereby entraining fluid and particles from the collection chamber to be carried to the drain.

Title: Planar dielectric line and integrated circuit using same
Inventor: ISHIKAWA YOHEI
IPC: H01L27/04
Filed: 1996-03-28
Abstract: A small and inexpensive planar dielectric line that can be easily connected to electronic parts, such as ICs, and having lower conductor losses. The planar dielectric line includes a dielectric substrate having first and second surfaces opposedly facing each other. A first slot having a predetermined width is interposed between first and second electrodes on the first surface of the dielectric substrate. A second slot having the same width as the first slot is disposed between third and fourth electrodes on the second surface of the dielectric substrate. The first and second slots opposedly face each other. The permittivity and the thickness of the dielectric substrate are determined so that a plane electromagnetic wave can propagate in a propagation region of the substrate interposed between the first and second slots while being totally reflected on the first surface of the substrate adjacent to the first slot and the second surface of the substrate near the second slot. First and second conductive plates may be spaced on both sides of the planar dielectric line. A further dielectric material may be disposed between the planar dielectric line and each of the conductive plates.      The above-described planar dielectric line may be part of an integrated circuit.

Patent CA-2174682-A1 (CA)
Inventor: ARDON MENACHEM TSUR
IPC: H04L12/44
Filed: 1996-04-22
Abstract: This invention relates to arrangements for interconnecting a plurality of stand-alone switches by data and communication channels (the latter typically used for communicating voice signals) in such a way as to make the plurality of switches act as if they were one switch. The invention further relates to arrangements for permitting groups of lines, the groups connected to different stand-alone switches, to be treated essentially as if they were connected to a single switch. Each switch of a symbiotic network (a group of stand-alone switches) or a virtual symbiotic network (the grouping of the groups of lines) accesses pertinent data in its own data base or the data base of one of the other switches of the symbiotic or virtual symbioticnetwork and treats the results of such data base accesses as if they were made internally in the switch. For a symbiotic network the trunks of all the switches of the network going to a common destination (and one such common destination can be any of the switches of another symbiotic network) are grouped into a single group so that an outgoing call can readily be made over a trunk connected to any of the switches of the symbiotic network. Similarly, incoming trunks to any switch of the symbiotic network from a common external source can be grouped into a single trunk group at that external source (which can be another symbiotic network). Advantageously, such an arrangement provides a convenient way of achieving the advantages of a giant switch without requiring the capacity of such a switch andwithout requiring the geographic concentration of traffic necessary to keep the links to a giant switch reasonably short. Advantageously, a virtual symbiotic network provides an economical and flexible solution to the problem of providing services such as wide area Centrex.

Title: Ozone enriching method
Inventor: SANUI HIROSHI
IPC: B01D53/04
Filed: 1996-02-05
Abstract: An ozone enriching method which comprises passing a plurality of adsorption columns packed with an adsorbent having the capability of preferentially adsorbing ozone through successively the step of holding the adsorbent at a low temperature to adsorb ozone, the step of heating the adsorbent to desorb ozone and introducing a given amount of a scavenging gas into the adsorbent after the completion of the desorbed ozone entrained by the scavenging gas, and the step of cooling the adsorbent after the completion of the desorption step is conducted under predetermined temperature rise conditions depending upon the time taken from the initiation of the desorption to the temperature for the adsorption step, thereby enriching ozone. Heating of the adsorbent in the desorption step is conducted under predetermined temperature rise conditions depending upon the time taken from the initiation of the desorption or the concentration of ozone in the gas to be discharged. A gas having a predetermined pressure is used as the scavenging gas in the desorption step. The adsorption step is conducted in two stages, a pre-adsorption step and a main adsorption step. A low-temperature oxygen is used as a cold source in the cooling step and, after use, fed as a starting material for ozone into an ozonizer.

Inventor: LANGLEY NEAL ROGER
IPC: G01N11/08
Filed: 1997-06-27
Abstract: The yield stress of rheologically plastic fluids such as coatings, sealants, and personal care lotions, determines their tendency to flow at low gravitational stress. Yield Stress is the apparent threshold stress above which flow is observed on an arbitrary time scale. An on-line technique to monitor yield stress during processing was developed herein and is used in controlling the slump or non-slump behavior of such products. A residual stress, after a flow excursion returns to zero shear rate, is related to yield stress. This residual stress is used for process monitoring. It is measured from the residual pressureor torque after a controlled strain rheometer reaches zero strain rate.
