Title: Method for joining heat exchanger tubes with headers
Inventor: KATO HISATAKA
IPC: F28F9/18
Filed: 1990-05-21
Abstract: In a method for joining a plurality of heat exchanger flat tubes (1) with headers (3) of a heat exchanger: each of the opposite end portions of the flat tubes (1) has a cross section provided with a major axis and a minor axis; opposite major axis side walls (6) of the cross section of each of opposite end portions of each of the flat tubes (1) are obliquely cut off so as to form each of opposite minor axis side walls (5) of the cross section of the end portion of the flat tube into a trapezoidal shape; the end portion of the flat tube is passed through an elliptical hole (4) formed in the header (3); the end portion of the flat tubes (1) thus passed through the header is flared over its entire peripheral wall; the thus flared (5,7 in Fig 2) end portion of the flat tube (1) is then bent (Fig 3) so as to be formed into a bent portion (10,11) of the flat tube (1), which bent portion (10,11) constitutes an essential part of a joint formed between the flat tube (1) and the header (3); and the thus formed joint is dipped into a molten filler metal bath to form brazing portions around the joint.

Patent EP-0423999-A1 (EP)
Inventor: BERKEY GEORGE EDWARD
IPC: G02B6/38
Filed: 1990-10-08
Abstract: A method is described of forming a tapered aperture at the end of a capillary tube bore (12). A gaseous etchant (22) such as a fluorine-containing compound flows through the bore (12) and emanates from the first end (14) of the tube (10). That tube end is heated to create a longitudinal temperature gradient. The gaseous etchant reacts with the tube (10) and enlarges that portion of the bore (12) at the first end. The resultant tapered aperture has a surface smoothness and shape that greatly facilitates the insertion of optical fibers during the fabrication of optical energy transfer devices.

Abstract: L'appareil à rayons X décrit, qui est de préférence conçu pour des mammographies et biopsies, comprend un bras tubulaire (1), qui est fixé rotatif par rapport à un cadre de base (4) et qui soutient le tube à rayons X (2). L'appareil comprend en outre un plateau de support (20), un bol de compression (25) et un porte-cassette de film (19) qui sont montés mobiles entre eux. Pour obtenir un tel appareil à rayons X avec instrument stéréotactique simple, qui est rapidement monté sur l'appareil à rayons X et qui élimine la nécessité coûteuse de recourir à deux plateaux de support et porte-cassette de film, le dispositif de localisation et le dispositif porte-aiguille de l'instrument stéréotactique sont combinés pour former une unité combinée pouvant être fixée dans le porte-bol de compression (21) de l'appareil à rayons X. Le porte-bol de compression (21), le plateau de support et le porte-cassette de film sont montés mobiles le long d'un guide (18) situé sur un second bras (17). Le second bras (17) et le bras tubulaire (1) étant réglables sur diverses positions angulaires relatives, il est possible de procéder à des expositions stéréotactiques et ensuite à une biopsie.

Title: Segmented seal for rotary equipment.
Inventor: HANSEN IB TJ RNTVED
IPC: F27B7/24
Filed: 1990-05-31
Abstract: In a sealing assembly for effecting a rotary seal between a stationary housing (5) and a rotary drum (1) by means of a number of arcuate sealing segments (8) engaging a radial sealing surface (6) on the housing (5) and a non-radial sealing surface (3) on the rotary drum (1), the segments being held into sealing engagement with said sealing surfaces by constantly acting means, the novel feature consists in that the non-radial surface (3) tapers conically towards the radial surface (6). With this arrangement, the radially acting means, such as a cable (15), urging the segments (8) radially inwards, also provide the requisite force for urging the segments towards the radial sealing surface (6), as the reaction force on the non-radial or conical surface (3) has a component directed towards the radial sealing surface (6). This, of course, makes the assembly simpler, more reliable in operation and less costly to produce than previous assemblies, in which the non-radial surface was cylindrical, and separate means had to be used to urge each segment into sealing engagement with the radial sealing surface.

Abstract: Un appareil d'imagerie à charge couplée comprend dans un substrat (12) en matériau semiconducteur, une pluralité de photodétecteurs (16) espacés, agencés en ligne. Les photodétecteurs (16) sont chacun d'un type pouvant être complètement appauvri. Un photodétecteur (16) approprié est une photodiode à régions P-I-N. Une région (18) d'accumulation séparée est contigue à un côté de chacun des photodétecteurs (16). On applique un potentiel à chaque région (18) d'accumulation formant un puits (38) d'accumulation dans ladite région, lequel est plus profond que celui se trouvant dans sa photodiode respective, de sorte que des porteurs de charge générés dans la photodiode s'écoulent de manière continue dans ladite région (18) d'accumulation. On a prévu un drain (24) anti-flou à proximité de chaque région (18) d'accumulation, la barrière de potentiel se trouvant entre ledit drain (24) anti-flou et ladite région (18) d'accumulation se trouvant au-dessous du puits de potentiel situé dans la photodiode de sorte que lorsque ladite région (18) d'accumulation se remplit de porteurs de charge jusqu'au niveau de la barrière de potentiel, les éventuels porteurs de charge supplémentaires débordent dans ledit drain (24) anti-flou. Cet agencement maintient le niveau du puits (38) de potentiel dans ladite région (18) d'accumulation au-dessous de celui se trouvant dans la photodiode, afin de permettre l'écoulement continu de porteurs de charge de ladite photodiode jusque dans ladite région d'accumulation. Un registre (20) de décalage de dispositif à couplage de charge s'étend le long de la ligne de ladite région (18) d'accumulation, et comporte une porte (29) de transfert permettant le transfert des porteurs de charge se trouvant dans les régions (18) d'accumulation, jusque dans ledit registre (20) de décalage.

Abstract: Procédé et appareil d'enduction d'un dispositif de fixation présentant des parties de tête et de tige. L'invention comprend les étapes et l'appareil de transfert des dispositifs de fixation à partir d'un mécanisme d'amenée, de sorte que les dispositifs de fixation sont positionnés pour être enduits. Lesdits dispositifs de fixation sont ensuite transportés dans une pluralité de postes de commande, commençant avec un poste de chauffage où les parties de tige des dispositifs de fixation sont chauffées. Ensuite, au niveau d'un poste d'application de matière, une matière de revêtement est appliquée sur les parties de tige chauffées. Un mode de réalisation préféré du procédé et d'un appareil de l'invention, consiste à utiliser un support magnétique afin de transporter les dispositifs de fixation horizontalement par leurs parties de tête, à chauffer la partie de tige jusqu'à une température supérieure au point de fusion de la matière appliquée, et à appliquer la matière à la partie de tige chauffée afin de former un revêtement sur cette dernière. Les supports magnétiques font partie d'une bande de transport sans fin en rotation continue. Les supports des dispositifs de fixation comportent des dents s'engageant dans une crémaillère afin de mettre en rotation les dispositifs de fixation. Un convoyeur assure un refroidissement par air supplémentaire aux dispositifs de fixation enduits, lesquels peuvent continuer à tourner. L'invention concerne également une roue de transfert dotée de deux ensembles d'entailles, laquelle est couplée de manière synchrone à la bande de transport afin de placer et d'aligner les dispositifs de fixation sur la bande pour les enduire.

Abstract: The method and the apparatus serve for monitoring filling devices in differential metering balances. In metering balances of this type, there is provided between a preceding bunker and a supply container a closing device for the cyclical filling of the supply container, which device is opened in the event of a predeterminable minimum filling of the supply container and is closed in the event of a predeterminable maximum filling. In a first filling and metering operation, a weight trend against time is fixed or predetermined as a reference trend and is stored so that it can be called up. During weighing operation, the weight trend is determined continuously during the filling and metering operation and is compared with the predetermined reference trend. If the weight trend determined differs from the reference trend by a determinable amount, the latter is signalled or otherwise indicated as defective to the closing device. <IMAGE>
