Patent CA-2391861-A1 (CA)
Title: Engrenages helicoidaux doubles opposes en poudre comprimee et procede
Inventor: HINZMANN GERD
IPC: B22F3/03
Filed: 2000-08-11
Abstract: L'invention concerne une presse à poudre métallique à actions multiples, qui sert à fabriquer des comprimés crus d'engrenages hélicoïdaux doubles. La presse comporte des poinçons inférieurs intérieur et extérieur, et un poinçon supérieur extérieur. Les poinçons extérieurs supérieur et inférieur ont des profils hélicoïdaux externes gauche et droit choisis en vue de produire un engrenage hélicoïdal voulu. Les poinçons coopèrent avec des matrices hélicoïdales gauche et droite portées par la presse autour des poinçons. Les faces hélicoïdales nécessitent que les matrices tournent par rapport aux poinçons quand la presse est en marche. Un mécanisme à came et à galets peut entraîner cette rotation. Le procédé de façonnage de comprimé commence dans une position ouverte, dans laquelle la poudre est introduite dans une cavité de matrice inférieure libre. Les parties supérieures de la presse avancent vers le bas pour fermer la cavité. Tous les éléments de la presse, à l'exception du poinçon intérieur inférieur, ou de transfert, se déplacent ensuite vers le bas à la même vitesse pour transférer la poudre vers les extrémités de la cavité. Lorsque le transfert est achevé, les deux poinçons inférieurs peuvent être arrêtés, alors que les poinçons supérieurs continuent à avancer. Les matrices avancent en tournant partiellement à une vitesse égale à la moitié de celle des poinçons supérieurs. Une fois que la poudre a atteint sa densité comprimée, les poinçons supérieurs et inférieurs s'arrêtent, mais les matrices continuent à tourner, se séparant de l'élément comprimé. Finalement l'élément est éjecté et la presse retrouve son état initial.

Title: Hot runner manifold system
Inventor: RUF STEFAN
IPC: B29C45/27
Filed: 2000-11-04
Abstract: The invention relates to a hot runner distributor system for an injection molding die for simultaneously injection--molding several or large parts. Said hot runner distributor system comprises a plurality of injection nozzles or openings (24) that are designed to deliver, at a substantially identical point in time, the injection molding mass under high pressure and at high temperatures to the predetermined zones of the mold. Said zones of the molds are at least partially disposed on separate main distributors (11, 12, 13, 14) that are provided with hot runners (17, 19, 21, 23) and are linked with a gate (1) for the injection molding mass via pre-distributors (2) which in turn are provided with hot runners (4, 7). The aim of the invention is to provide an improved hot runner distributor system that overcomes at least a part of the drawbacks of the prior art, that is, that is more lightweight and compact. To this end, at least a part of the pre-distributors (2) is interposed between adjoining main distributors (11, 12, 13, 14), the hot runners (7, 17) of the pre-distributors (2) and the main distributors (11, 12, 13, 14) leading to the lateral surfaces (15, 25) facing each other. The main distributors (11, 12, 13, 14) and the pre-distributors (2) are closely and tightly forced against one another by lateral spring elements (6), said spring elements (6) allowing a limited movement of the main distributors (11, 12, 13, 14) against the spring resistance.

Patent CA-2396409-A1 (CA)
Title: Pressure relief apparatus
Inventor: BRAZIER GEOF
IPC: F16K31/56
Filed: 2001-01-05
Abstract: A pressure relief apparatus includes a valve having a body. A shaft is rotatably disposed in the body and has an exterior end extending through the body. A  plug, which may contain an internal passageway, is mounted on the shaft and is disposed in the fluid flowpath. The body is engageable with the system to expose the plug to the pressurized fluid so that the pressurized fluid acts on the plug to exert a torque on the shaft which is offset from the center line of the plug.  The apparatus further includes a linkage assembly configured to translate the torque exerted on the shaft into an output force. A release device, such as a buckling pin, a magnet, an electromagnet or a fusible plug, is connected to the linkage assembly and is configured to release the shaft when the output force exceeds a predetermined limit. Preferably, the linkage assembly is adjustable to vary the magnitude of the output force corresponding to a given torque. A low torque seal secured in place by a retaining ring is disposed in the body to prevent fluid from leaking through the body past the plug.

Abstract: A formulation for male contraception comprising a progestin prossessing both estrogenic and androgenic properties is remarkably effective for spermatogenesis suppression in males. The progestin Norethisterone (NET), particularly its derivatives Norethisterone acetate and Norethisterone enanthate in sufficient doses induce oligozoospermia or azoospermia in males.  Formulations further comprising an androgen, such as a testosterone derivative such as a testosterone ester, particularly testosterone undecanoate, are especially effective male contraceptive formulations.

Patent CA-2402639-A1 (CA)
Title: L-leucyl-l-leucine methyl ester treatment of donor lypmhocyte infusions in hematopoietic stem cell transplant patients
Inventor: KORNGOLD ROBERT
IPC: A61K35/12
Filed: 2001-03-09
Abstract: The present invention relates to a method of inhibiting graft-versus-host disease in allogeneic hematopoietic stem cell transplant (HSCT) patients by using L-leucyl-L-leucine methyl ester (LLME) to eliminate selective cytotoxi c T cells in donor lymphocyte infusions (DLI). LLME has been shown to inhibit GVHD in animal models by selectively inducing apoptosis in natural killer cells and cytotoxic T cells. The application of LLME to the human clinical HSCT situation, however, has been hampered by HSC toxicity when useparated marrow is treated at the concentrations necessary to purge GVHD-inducing T cells prior to infusion. In the present invention, this problem is circumvented by the LLME ex vivo treatment of DLI administered following transplantation of T cell-depleted HSC. In this setting, the effects of LLME  on HSC contained within the DLI are irrelevant for clinical outcome. In another embodiment, the risk of toxicity to the stem cell population is avoided by ex vivo LLME treatment of donor lymphocytes after separation of CD34+ stem cells and then co-administration of the LLME-treated donor CD34- fraction and the untreated CD34+ stem cells.

Abstract: A method for preparing cross-linked collagen, and cross-linked collagen products. The method includes incubating collagen in a solution including water, at least one polar solvent and at least one sugar, to form cross-linked collagen. The accompanying figure shows the effect of treatment with reducing sugar (D-ribose) and alcohol on particulate collagen degradation by bacterial collagenase. The solution may include a buffer having a suitable pH and ionic strength. The method may include removing excess unreacted sugar(s) and polar solvent(s) by washing the cross-linked collagen or by other methods. The method may also include dehydrating the cross-linked collagen, and may include subjecting the cross-linked collagen to critical point drying, or subjecting the collagen to drying or freeze-drying prior to cross-linking. The collagen may be prepared from atelopeptide collagen to reduce antigenicity, but may also be prepared from other suitable collagen types. The concentration and type of the polar solvent(s), the concentration and type of the reducing sugar(s), and the incubation duration may be varied to control the degree of cross-linking. The cross-linked collagen product may be in the form of a wet or dry matrix or membrane or may be suspended in a liquid in the form of an injectable preparation. The method may be applied to collagenous proteins and collagen-like peptides.
