Patent CA-2205408-C (CA)
Inventor: SIMPSON JACK R
IPC: B26D7/18
Filed: 1997-05-15
Granted: 2006-03-21
Abstract: An elongated rubber ejector is mounted to a die board that forms a part of a cutting die and the ejector functions to engage cut corrugated board and eject the same from the cutting die. The rubber ejector includes upper and lower faces or surfaces with each face including a series of spaced apart raised lugs with a series of spaced apart voids or relief areas disposed between the lugs. Lugs and relief areas formed on one face are staggered with respect to the lugs and relief areas formed on the other face. In practice, the lugs are compressed during a die cutting operation. Once the corrugated board has been cut and the die board and an opposed anvil have been moved apart, the lugs and the ejector expand and in the process the rubber ejector engages the cut corrugated board and ejects the same from the cutting die.

Title: Adjustable bubble guide or cage
Inventor: KRYCKI ROBERT D
IPC: B29C48/90
Filed: 1998-02-18
Granted: 2006-11-28
Abstract: A bubble guide unit according to the present invention comprises two concentric frames, at least one of which rotates relative to the other, through which the film bubble passes. At least four bubble guiding rods are arranged symmetrically to each pivotally engage one frame at one end and to freely engage the other frame near its other end. Freely engage here means that the other end of each rod is free to pivot to some extent as well as to move in the direction of its length beyond the pivoting point and back. This is most. easily accomplished by a pivoting ring through which the rod passes or, less elegantly, by a fixed ring having an aperture larger than the rod~ diameter.

Abstract: L'invention concerne un procédé de régularisation du recuit d'affinage structural de certains alliages d'aluminium. On détermine, pour le procédé de coulage utilisé, les dimensions du grain en fonction des différentes valeurs de l'indice de croissance du grain. Cet indice est représenté par la somme de la valeur m(k-1) multipliée par la concentration de chaque élément dans l'alliage d'aluminium. Si on compare la valeur d'un certain alliage avec des rapports connus entre la valeur m(k-1) et la dimension du grain, on amende la composition de l'alliage en fusion en lui ajoutant un agent modifiant la dimension du grain, afin d'obtenir une dimension optimale. On peut encore améliorer ce procédé en optimisant la quantité d'agent de nucléation.

Abstract: L'invention porte sur un procédé de mesure du profil de densité d'un matériau en plaque M dont la densité varie par échelons ou régulièrement dans l'épaisseur, la densité à une profondeur donnée de la plaque M étant de préférence réputée constante. Ledit procédé recourt à des rayons X ou .gamma. émis par une source K placée d'un côté de la plaque M alors qu'au moins deux détecteurs T et F sont disposés du côté opposé de la plaque sans fin qui progresse pendant la mesure dans le sens longitudinal. Le premier détecteur T, de préférence placé dans la direction d'émission de la source, mesure le rayonnement traversant la plaque M, et le second détecteur F, placé hors de la direction d'émission de la source K, mesure le rayonnement diffusé par les différents volumes partiels jalonnant la direction d'émission. Il est possible de déterminer la densité de chacun des différents volumes partiels à partir des mesures effectuées par les détecteurs. L'invention prévoit de plus une compensation des rayonnements à diffusion multiple consistant à déduire le rayonnement mesuré du rayonnement à diffusion multiple.
