Patent CA-2322782-C (CA)
Title: Carton ondule retriturable
Inventor: BERUBE SERGE
IPC: B05D1/00
Filed: 1999-03-02
Granted: 2009-11-24
Abstract: L'invention concerne une composition de revêtement pour la couverture du carton ondulé qui assure une imperméabilité à l'eau et aux graisses, mais qui est perméable à la vapeur d'eau et qui permet de ce fait de fabriquer de manière différente du carton ondulé lorsque l'on utilise des adhésifs aqueux dans l'ensemble de la couverture et du support ondulé. Plus précisément, la couverture peut être enduite de la composition de revêtement avant l'assemblage du carton ondulé parce que le revêtement perméable à la vapeur d'eau permet l'évacuation de l'eau de l'adhésif aqueux pendant le séchage des composants assemblés du carton ondulé. La composition de revêtement utilise un copolymère styrène-acrylate et un complexe d'acides gras C14-C18 d'un ion métallique présentant un état d'oxydation d'au moins 3, comme le chrome.

Abstract: An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery is continuously recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and provides the electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.
