Patent CA-2116997-C (CA)
Title: Bag structure and pad
Inventor: SETTON SIMON
IPC: B65D81/26
Filed: 1994-03-04
Granted: 1999-01-12
Abstract: A bag for packaging food products that exude juices, such as meat and poultry, incorporates therein an  absorbent  pad  which  is  sandwiched  between  an impervious  surface  layer  and  a  pervious  layer  and retained against a lower section of the rear side wall of the bag   by a retention strip made of bondable material.  The retention strip may be a strip of heat-fusible material or an adhesive tape.   The retention strip extends transversely across the rear side wall and an uppermost edge of the pad, and if heat-sealed, two  fused lines  are  formed.   The  first  fused line extends  longitudinally  along  a  leading  edge  of  the retention strip and forwardly of the uppermost edge of the pad.   A second fused line extends longitudinally across the strip, over the top impervious surface layer of the pad and on the bag rear side wall of both sides of the pad.   This strip maintains the pad in position in the lowermost section of the bag and prevents the disturbance and withdrawal of the pad when the food products are inserted and removed from the bag.

Inventor: SHAW GORDON
IPC: B01F27/73
Filed: 1995-11-09
Granted: 2005-11-29
Abstract: A polycondensation reactor for processing low viscosity polyester or another polymer into relatively highly viscosity polymer comprises a substantially cylindrical horizontal reactor vessel with a polymer inlet and a polymer outlet adjacent its opposite ends and a vapour exhaust opening in the upper side of the vessel at its outlet end. A polymer agitator is rotated axially within the chamber and includes plural alternating annular overflow and underflow baffles and multiple perforated film-forming screens disposed therebetween in parallel spaced relation to one another. The overflow baffles are in periphery polymer-sealing relation to the vessel while the underflow baffles have multiple underflow recesses in their outer peripheries, whereby the baffles define a tortuous polymer flow path alternately through their respective polymer overflow and underflow openings to control residence time, distribution and viscosity growth as the polymer flows between the baffles. The baffles and screens are integrally fixed coaxially at their outer peripheries by axially extending wiper bars. Aligned openings in the baffles and screens along the rotational axis of the agitator provide for free flow of volatiles to the exhaust opening.

Granted: 2002-03-12
Abstract: Dans un système de conservation (170) destiné à une mémoire non rémanente (172) associée à une mémoire rémanente (171), une partie de stockage d'énergie accumule de l'énergie pendant l'alimentation en régime normal. Lorsqu'une panne d'alimentation se produit, l'énergie stockée est fournie à la mémoire non rémanente. Une énergie de secours suffisante est stockée pour permettre de compenser la majorité des interruptions accidentelles d'alimentation. Ensuite, après suppression de l'alimentation extérieure, lorsque l'alimentation de secours diminue jusqu'à atteindre une quantité prédéterminée, les données se trouvant dans la mémoire non rémanente sont transférées vers la mémoire rémanente. L'utilisation préférée du système de conservation s'inscrit dans un environnement à vibrations et/ou phénomènes transitoires de commutation d'alimentation affectant l'alimentation en énergie, tel qu'un avion.
