IPC: H02J7/00

Abstract: An equalizer for equalizing the charge on several series-connected cells includes a transformer having plural windings on a core corresponding to the number of cells. The windings are tightly coupled to one another.  A switching device such as a MOSFET is connected to each of the windings, and a winding and a switching device are connected across each of the cells.  The switching devices are simultaneously switched at a relatively high frequency, e.g., 20Hz, and the voltage across the highest charged cell appears across each of the windings when the switching devices are on.  Current flows from the most highly charged cell to a cell or to cells of lower charge, with the charging current being proportional to the difference in voltage between the highest charged cell and each of the lesser charged cells.  Equalization is carried out with very little power consumption by the equalizer, allowing charging to take place in a rapid manner.
Patent CA-2159652-A1 (CA)
Inventor: KRYLOV GENNADY
IPC: F25C1/14
Filed: 1995-10-02
Abstract: Apparatus and the process are designed to produce potable water and slush from sea water. The apparatus combines the unique desalination capabilities of the REVERSE OSMOSIS process in the first stage and the SLUSH making process on the second stage. The special feature of the apparatus is of using the high concentrated brine waste from the REVERSE OSMOSIS process to produce the low temperature (minus 2°C to minus 3°C) SLUSH. This combination renders apparatus free of "freeze-up" troubles, allowing the fishermen to stay in the open sea for significantly longer time having CONTINUOUSLY portable water as well as Slush for the catch preservation. Furthermore, the combination of the desalination and refrigeration technologies increases the water purification efficiency or recovery rate of the REVERSE OSMOSIS process up to twenty percent.

Abstract: A milling cutter head intended primarily for aluminum machining comprises grooves (4) in which are mounted cutting insert-carrying cartridges (2) and spacer plates (3). Those sides of the cartridge and the spacer plate that are in contact are serrated in the same direction. The other side of the spacer plate and the side surface of the groove being in contact with it are serrated in a direction which is perpendicular to the first mentioned serration. In this way it is possible to independently of each other and precisely adjust the cutting edge both axially and radially.

Filed: 1995-01-18
Abstract: A minimally-invasive surgery apparatus (10) for causing the lumen of a vein to collapse to prevent blood flow through the vein, e.g., a varicose vein or a side branch of the saphenous vein, includes an electrode (20) which is electrically connected to a power source (14), and the electrode (20) is percutaneously advanced into the vein. Then, the power source (14) is activated to energize the electrode (20) and thus the blood vein until the blood vein sufficiently collapses to block the lumen of the vein.

Patent CA-2182243-A1 (CA)
Inventor: GARLAND STUART MANDEL
IPC: H04M3/00
Filed: 1996-07-29
Abstract: The invention uses a suppressed ringing connection, switched through the existing call processing switch fabric, to connect two CPEs for long duration, low priority calls. The suppressed ringing connection is implemented such that the connection is disconnected if an incoming call to one of the CPEs or an outgoingrequest for service from one of the CPEs is made. If the suppressed ringing connection is disconnected due to a request for normal service to or from one of the CPEs, the system of the invention automatically reestablishes the suppressed ringing connection after the normal service call has ended such that the long duration suppressed ringing connection can be maintained on a quasi-permanent basis. As aresult, the suppressed ringing connection can be maintained for long duration connections without disrupting normal incoming or outgoing service to either of the connected CPEs.

Abstract: A waste container has a base and a lid.  The lid is connected to the base by a coil spring hinge that biases the lid to an open condition.  A latch mechanism includes a deformable wall section on the lid and a pivotable latch member on the base with a curved end to effect a force fit therebetween when the lid is  closed  and pressed downwardly.    Movement  of  the  latch disengages the base latch member from the lid wall section and starts movement of the lid in a direction to open it.  Further, lid movement towards an open position is then caused by the spring hinge to fully open the lid.
