Abstract: Procédé de fabrication d'une bande de papier ayant un rapport de traction faible. Ledit procédé consiste à faire sortir, de manière pratiquement horizontale, de la pâte de papier (S) d'une caisse de tête (12), à recevoir la pâte de papier dégagée (S) sur un premier fil bouclé (14) disposé de manière pratiquement horizontale, se déplaçant pratiquement à la même vitesse et dans la même direction que la pâte de papier dégagée (S). Le dispositif est tel qu'une première quantité d'eau (18) est ôtée de la pâte de papier dégagée (S) vers le bas, à travers le premier fil (14) pendant le passage de la pâte de papier dégagée (S) à travers une zone d'égouttage initiale (20). La pâte de papier partiellement égouttée est prise en sandwich entre le premier fil (14) et un second fil bouclé (22), lesdits fils (14, 22) formant entre eux une zone d'égouttage secondaire (24) pour un nouvel égouttage de la pâte à papier dégagée. Une seconde et une troisième quantité d'eau (28, 30) sont enlevées vers le bas et vers le haut respectivement, à travers le premier et le second fil (14, 22) pendant le passage de la pâte de papier dégagée sur un patin incurvé (26). La courbure de la zone d'égouttage secondaire (24) est inversée de manière que les fils (14, 22) s'étendent autour d'une boîte renversée incurvée (34) reliée à une source de vide partiel (36) afin qu'une quatrième quantité d'eau (38) soit ôtée par le haut à travers le second fil (22) et aspirée par la boîte incurvée (34). Le dispositif est tel qu'un égouttage progressif de la pâte de papier dégagée est effectué pendant le passage de la pâte de papier (S) à travers les zones d'égouttage initiale et secondaire (20, 24), ce qui empêche le détachement de fines de la pâte de papier dégagée et minimise le rapport de traction de la bande de papier qui en résulte (W).

Title: Adaptive cache miss prediction mechanism
Inventor: RYAN CHARLES P
IPC: G06F12/08
Filed: 1993-02-12
Granted: 1996-08-27
Abstract: In a data processing system which employs a cache memory feature, a method and exemplary special purpose apparatus for practicing the method are disclosed to lower the cache miss ratio for called operands. Recent cache misses are stored in a first in, first out miss stack, and the stored addresses are searched for displacement patterns thereamong. Any detected pattern is then employed to predict a succeeding cache miss by prefetching from main memory the signal identified by the predictive address. The apparatus for performing this task is preferably hard wired for speed purposes and includes subtraction circuits for evaluating variously displaced addresses in the miss stack and comparator circuits for determining if the outputs from at least two subtraction circuits are the same indicating a pattern yielding information which can be combined with an address in the stack to develop a predictive address. The cache miss prediction mechanism is adaptively selectively enabled by an adaptive circuit that develops a short term operand cache hit ratio history and responds to ratio improving and ratio deteriorating trends by accordingly enabling and disabling the cache miss prediction mechanism.

Abstract: The invention relates to a method for the preparation of polyolefins by polymerizing olefin by using a procatalyst composi-tion prepared by bringing together magnesium chloride, a lower alcohol, a titanium compound, and phthalic acid ester. The in-vention also relates to the said procatalyst composition.

Title: Fire fighting bucket for aircraft
Inventor: NEEDHAM ROBERT DAVID
IPC: A62C3/02
Filed: 1994-05-24
Granted: 2005-01-04
Abstract: A collapsible fire fighting bucket assembly to be suspended from an aircraft for fighting wild fires, the bucket being made of pliable material and having an open upper end for filling from a body of water. A tubular extension extends from an opening in the bottom of the bucket and has a free end formed with a discharge port provided with resilient sealing lips which are brought into sealing engagement with each other to close the port to minimize water leakage from the tubular extension. A harness suspends the bucket from the aircraft and a releasable support releasably supports the free end of the tubular extension within the bucket body extending upwardly from the opening to close the discharge port. The releasable support cooperates with the openings to allow the tubular extension to be rapidly lowered so as to extend downwardly from the bottom to open the discharge port for dumping the water. The sealing lips are drawn together by purse lines passing through openings adjacent the discharge port but spaced from the sealing lips to avoid abrasion of the lips that occurred with prior art bucket valves. The purse lines cooperate with the releasable support to control location of the free end of the tubular extension.
