Patent CA-2404185-A1 (CA)
Inventor: MERCIER CLAUDE
IPC: H02M3/07
Filed: 2002-09-19
Abstract: A capacitive pump circuit suitable for use in loop powered level measurement and time of flight ranging systems. The capacitive pump circuit comprises an input buffer, a level shifter and an output stage. The input buffer receives a clocking signal which is also coupled to the input of the output stage through the level shifter. The output from the input buffer is switched by the output stage to charge a capacitor and generate a voltage output which has the opposite polarity of the voltage supply rail. According to another aspect, a capacitive voltage doubter circuit is provided which is also suitable for use in loop powered level measurement and time of flight ranging systems.

Title: Bag-in-box container for liquids
Inventor: YORN KENDALL L
IPC: B65D77/06
Filed: 2002-10-10
Abstract: This invention is directed to an improved bag-in-box apparatus for containing and dispensing liquids such as beverages.      The interior surface of the bottom of the box (20) is preferably sloped downward toward the spout (12) of the bag (10) such tat gravity helps feed the liquid toward the spout (12). In lieu of or in conjunction with slopes, the interior bottom surface of the box (120, 130, 150, 140, 160) may have terraces (34), curves (132, 134), corrugations (152), fan-like ridges (142), or beams (162). The present invention thereby reduces the amount of residual liquid as the liquid is withdrawn from the bag (10) without the need for an evacuation strip or a special slanted rack. Although the primary intended application of the present invention is in bag-in-box packages for containing and dispensing beverages, this invention may also be used to advantage in other liquid dispensing applications.
