Title: Lock-up system for cutting mat
Inventor: BRYSON RONNIE E
IPC: B26D1/40
Filed: 2002-04-18
Granted: 2006-11-28
Abstract: A lockup device (146) for securing cutting mats (114) to a rotary anvil (100) comprises a base portion (122), one sidewall (132), and a wedge portion (134), and is adapted to be inserted into the channel (110) of the rotary anvil such that the sidewall (132) of the lockup device is adjacent a wall of the channel (110). A cutting mat (114) having opposing first and second flanged ends (116, 118) is wrapped around the rotary anvil (100). The first flange (116) is compressed between the locking wedge (134) and the sidewall (132) of the lockup device. The second flange (118) is compressed between the locking wedge (134) and a channel wall (168). As such, the locking wedge (134) and cutting mat (114) are frictionally secured to the rotary anvil (100). Further, the cutting mat (114) may be quickly repositioned by releasing the second flange (118) from the channel (110). When the cutting mat (114) is unwrapped from the rotary anvil (100), the lockup device (146) remains secured to the first flange (116), allowing for quick repositioning.

Granted: 2013-07-09
Abstract: - Méthode et dispositif pour évaluer dans le même temps et avec le même appareillage, des paramètres physiques tels que la perméabilité absolue et la porosité, de fragments extraits d'un milieu poreux naturel ou artificiel fragmenté. - On mesure la porosité des fragments au moyen de tests de pression à l'hélium ou tout autre gaz, suivant un protocole connu en soi. L'enceinte qui les contient, est mise en communication avec un réservoir de volume connu également, contenant de l'hélium sous une pression connue. A l'équilibre des pressions, on peut déduire la valeur du volume solide. On mesure également le volume enveloppe de roche et la masse en fragments. En combinant ces mesures, on détermine la porosité des échantillons ainsi que la densité de la roche. On mesure ensuite leur perméabilité en les immergeant dans un liquide et en mettant l'enceinte en communication avec du liquide initialement sous une pression définie contenu dans un accumulateur de manière à comprimer le gaz piégé dans les pores de la roche. Par le biais d'une modélisation de l'évolution du volume de liquide injecté dans l'enceinte, et d'un ajustement itératif, on détermine les valeurs des paramètres physiques. - Applications par exemple à des mesures pétrophysiques à partir de déblais de forage ou de carottes concassées.

Title: Method for producing metallic powders consisting of irregular particles
Inventor: TORNBERG CLAES
IPC: B22F9/08
Filed: 2002-09-30
Granted: 2010-11-16
Abstract: The invention relates to the production of a metallic powder consisting of surface-fissured, so-called irregular particles, namely a water-atomised metallic powder. The aim of the invention is to obtain an irregular surface form of powder grains (23) in a narrow weight class and to impart a high porosity with a homogeneous distribution to the sintered body. To this end, in a first step, the pouring stream (2) is deviated in its flow direction and is enlarged on its surface, and in a second step, the surface-enlarged pouring stream (21) is deviated again its flow direction and is divided, and the liquid metallic particles (22) formed are accelerated, and in a third step, the displaced liquid metallic particles (22) are applied and divided, at an angle .gamma. of between 10 and 90~ in relation to the displacement direction of the same, with a high speed current (51) formed at least partially from a liquid medium, and the particles (23) are then solidified. According to one embodiment of the invention, in order to reduce the overheating of the metal melt and/or to improve the quality of the metallic powder produced, the pouring stream (2) is deviated in its flow direction and a surface enlargement of the same (21) is carried out, in a first method step, and/or the surface-enlarged pouring stream (21) is deviated and divided, and the formed liquid metallic particles (22) are accelerated, in the second method step, with at least one current (6,31,41) formed from at least one heated gas or heated gas mixture.

Inventor: OWENSBY JOSEPH E
IPC: C08J9/36

Granted: 2009-10-20
Abstract: There is provided a multi-layered foamed article. The foam article has a layer of foam material on either side of an inner peel layer disposed roughly in the middle of the foam. The portion of the foam in closest proximity to the peel layer is subjected to the greatest amount of heat during extrusion forming mostly large open cell foam. The foam near the surface of the multiplayer foam article is cooled by the atmosphere or contact with cooling surfaces and comprises mostly small closed-cell foam. There is also provided a method for making a multi- layer foamed article by co-extruding an inner peel layer sandwiched between two expanded layers of a foam material. Each of the expanded foam layers on either side of the peel layer of the article is easily peeled or stripped from the peel inner layer and the multi-layer article is converted into a foamed article with absorbing characteristics on one side and non-absorbing characteristics on the other side. Thus, the foam is predominantly open-cell on one side of the structure and predominantly closed-cell on the opposing side. The open-cell portion of the article is highly absorbent and easily soaks up liquids. The closed cell portion of the foam article acts as a waterproof layer preventing liquid from moving all the way through the thickness of the foam. After blowing the polymer melt, the extrusion product comprises a foam article with a peel layer disposed roughly in the middle of the foam. A preferred embodiment of the multi-layer article is polystyrene foam for the two outer layers and a polyethylene film as the inner peel layer.

Title: Movable barrier operator multi-technique excess force avoidance apparatus and method
Inventor: KELKHOFF BARBARA P
IPC: H02H7/085
Filed: 2004-05-27
Granted: 2008-11-25
Abstract: A movable barrier operator can use (11) a first technique to prevent an excess application of force during controlled movement of a movable barrier (43) and at least a second technique (12) to similarly prevent an excess application of force during such movement. Both techniques can then be utilized to determine (13) when an application of excess force may nevertheless occur and not be reasonably avoided. In one embodiment, two techniques (21 and 22) can be used to detect force as applied during movement of the movable barrier and such information can be used to determine (23) whether applied force is being reliably indicated. In another embodiment, travel limit information (51), travel information (52) and travel history information (53) are utilized to assess whether normal operation of the movable barrier operator should be over-ridden (54) due to a possibly expression of undue force.

Abstract: The roller bar chains of a continuous press for producing pressed board provided sufficient play for the roller bars relative to the link chains by having the journaling pins for the link chains extending through bushings which articulate the overlapping link plates together, so that the outer diameters of the pins within these bushings are less than the inner diameters of the bushings. The result is that the roller bar chain has only a single guide plane in the press region between the two press plates.
