Patent CA-2128507-A1 (CA)
Title: Method and Apparatus for Charging, Thawing, and Formatting a Battery
Inventor: PODRAZHANSKY YURY
IPC: H01M10/48
Filed: 1993-01-19
Abstract: A method and an apparatus for rapidly charging a battery. The preferred charging method comprises applying one or more charging pulses (C1, C2), separated by a waiting period (CW1), with the last charging pulse, if there are more than one, being followed by a second waiting period (CW2). This is then followed by a series of discharging pulses (D1, D2, D3), which are separated by waiting periods (DW1, DW2), and followed by a last waiting period (DW3) before the occurrence of the next charging pulse (C1). The discharging pulses preferably have a magnitude which is approximately the same as the magnitude of the charging pulses but which have a duration which is substantially smaller than the duration of the charging pulses. The discharging pulses serve to create and disperse ions throughout the electrolyte of the battery so that the ions do not shield the plates of the battery from further charge transfer. Multiple discharge pulses are used rather than a single discharging pulse so that natural chemical and electrical gradients within the battery will serve to disperse the ions more evenly throughout the electrolyte. The use of discharging pulses of an extremely small duration does not cause any significant discharge of the battery but does increase the rate at which the battery can be charged and the efficiency with which the battery can be charged, thereby minimizing charging time and battery heating. Also disclosed are a method and an apparatus for thawing and charging a frozen battery, for formatting a new battery, for determining the state of formation of a battery, and for determining the state of charge of a battery.

Title: Air separation method and apparatus to produce nitrogen
Inventor: MOSTELLO ROBERT A
IPC: F25J3/04
Filed: 1995-09-27
Abstract: An air separation method and apparatus for producing nitrogen is provided in which oxygen enriched liquid, produced as a column bottoms of a distillation column, is partially vaporized and phase separated. The vapor phase is expanded to provide refrigeration while the liquid phase, after pressure reduction, is introduced into the head condenser to condense reflux to the column. Alternatively, part of the oxygen enriched liquid can be fully vaporized and then expanded to provide refrigeration. In such case, another part of the oxygen enriched liquid can be used to condense reflux to the column. Part of the air to be separated is liquefied against the oxygen enriched liquid to be vaporized and then introduced into a lower portion of the column to maintain production and purity levels that would have been obtained had all the oxygen enriched liquid stream been used in condensing reflux to the column.
