Patent EP-0426377-A1 (EP)
Inventor: PROTO GEORGE R
IPC: A61B17/06
Filed: 1990-10-25
Abstract: An apparatus (26) is disclosed for attaching a surgical needle (20) having a generally cylindrical end portion defining an elongated aperture (22) having a generally circular cross-section and a suture (24) having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture (22) of the needle (20). The apparatus (26) includes a pair of dies (14), each having a generally arcuate surface portion (16) having irregularities including concave portions (18) such that when the cylindrical end portion of the suture (24) is positioned within the aperture (22) of the needle (20) and the dies (14) are positioned about the generally cylindrical end portion of the needle (20) with the surface portions facing the outer surface thereof, the application of inward force to the dies (14) causes the dies (14) to impact the needle (20) and produces inward crimping of the needle (20) so as to attach the needle (20) to the suture (24). The concave portions (18) define material relief zones to receive and collect deformed material from the needle (20) so as to avoid distortion of the needle (20). According to the invention, the symmetry of the needle (20) is maintained and the attachment is predictable and superior to those of the prior art. A method of forming such attachment is also disclosed.

Abstract: This is a method for growing antimony-doped silicon single crystal having an oxygen concentratlon of 12 ppma and more. 
     In this method the pressure of an atmospheric inert gas within the furnace is set at a range between 10 and 50 millibars, and also the reference rate of rotation of the quartz crucible is set at 5 rpm and more in pulling the antimony doped silicon single crystal having an antimony concentration of 6 x 10¹⁸ atom/cc and more from an antimony doped silicon melt contained in a quartz crucible according to the Czochralski process. 
     The reference rate of rotation can be increased in accordance with the increased length of the pulled single crystal, and further a pulse like change in rotation rate can be superimposed over the reference rate of rotation, so that the pulled single crystal can have a high and axially and radially uniform oxygen concentration throughout the entire length of the single crystal.

Abstract: Prior to slaughter, poultry are caused to undergo anoxic convulsions by exposure to an atmosphere for a sufficient period of time to lose consciousness. The poultry are then slaughtered. After slaughter, the poultry are chilled and then deboned or portioned. It is found that deboning or portioning can be performed within four hours of slaughter, instead of the conventional period of twelve hours or more, without adversely affecting the quality of the resultant meat. This result is attributed to the anoxic convulsions causing glycolysis in the pectoral and other muscles of the birds.

Abstract: Machine (10) de remplissage en ligne et procédé de remplissage de récipients (12). Dans certains modes de realisation une seule file de récipients est indexée devant une pluralité d'ajutages (56) de remplissage qui sont à leur tour reliés à un distributeur (48) recevant une seule charge de matière provenant d'une structure de dosage (26). Si tous les ajutages (56) procèdent simultanément à la distribution, une charge totale de matière reçue à la fois, lesdits ajutages distribuant des parties aliquotes de la charge totale à la file de récipients. Si l'on n'utilise lesdits ajutages que de manière alternée à n'importe quel moment, la charge fournie par la structure de dosage est proportionnelle à la charge totale si les ajutages distribuant la charge sont proportionnels au nombre total d'ajutages. Ladite structure de dosage comprend habituellement une seule pompe (30). Les cycles de temps de remplissage et d'indexage sont communément exécutés de manière séquentielle, mais dans certains modes de réalisation ils peuvent être exécutés simultanément. Ainsi dans une machine (Fig. 14) à double colonne dotée de deux files de récipients, les récipients se trouvant dans une file peuvent recevoir les parties aliquotes d'une charge totale, tandis que les récipients se trouvant dans l'autre file sont indexés, même si l'on n'utilise qu'une seule pompe (30).

Abstract: A transverse slot (5), passing through the ski, is provided in the central part (1) of the ski, in the area in which the boot (4) is held, the area of the heel (T) serving as a support for the foot during the sliding phase, and the metatarso-phalangeal area serving as an impulsion support (Pi) during the impulsion phase of the ski. The slot (5) defines, in the thickness of the ski, two flexing beam parts, an upper one (6) and a lower one (7), respectively. This arrangement permits, during the phase of impulsion (Pi), satisfactory flattening on the ground of the lower beam part (7) and thus of the running sole part of the ski comprising the wax chamber (8). The impulsion efficiency thereof is thus markedly increased without affecting the sliding phase.

Abstract: A butterfly valve contains a housing (2) in which a flap plate (4) is supported such that it can rotate as well as a sealing ring (12) which has a sealing surface and is arranged at least partially in a chamber (34), especially of the flap plate (4). The sealing ring (12) has a predeterminable number of partial reinforcements which consist of a material having a higher strength than the material of the sealing ring. Such a butterfly valve is intended to be developed to the extent that reliable sealing is ensured with a simple design and at a low cost even under the influence of critical flow conditions. It is proposed that the reinforcements be constructed as pins (48) which are arranged in a part of the chamber (34) having an increased length (40). The sealing ring (12) has a cross-section which is especially essentially T-shaped and has a broadened chambering part (44) in which a number of holes (46) are arranged for holding the pins (48). <IMAGE>
