Patent EP-0019551-A1 (EP)
Inventor: GUIGNARD PAUL
IPC: B23K33/00
Filed: 1980-05-14
Abstract: The invention concerns a process for the final assembly of a nuclear reactor vessel comprising two sub-assemblies which are brought together and welded along mating surfaces. At least three female centering stubs, each associated with a seat recessed relative to the outer surface of the stub, are provided on the mating surface of one of the sub-assemblies, and at least three male centering stubs, corresponding to the seats of the female stubs, are provided on the mating surface of the other sub-assembly, the positions of the stubs being registered relative to elements for positioning internal fitments of the vessel. The two sub-assemblies are brought together to engage the male stubs in the female stub seats and to bring projecting annular ridges on the mating surfaces into contact. A key is inserted into a socket defined by one of the pairs of stubs and the stubs are then joined to each other by point-welds. An annular space defined between the mating surfaces of the sub-assemblies and delimited by a wall provided by the contacting ridges is then partially filled with filler metal. The centering stubs, wall and part of the deposited metal are then removed before welding is completed by filling the gap between the mating surfaces with filler metal. The invention is particularly applicable to the assembly of vessels for pressurized-water nuclear reactors comprising upper and lower sub-assemblies, which are assembled in a horizontal position.

Abstract: In a method of manufacturing a picture display tube a gettering device is used which comprises a first metal holder (1, 20) and a second metal holder (3, 28). A source (2, 21) of evaporable gettering metal is accommodated in the first metal holder (1, 20) from which the gettering metal can be released by inductive heating. A gas source (6) of a material having a comparatively high decomposition temperature and releasing gas upon heating is accommodated in the second metal holder. The second metal holder is connected to an outer surface (7, 30) of the first metal holder in such manner that the second metal holder forms an electric shunt for the induction currents generated in the first metal holder by the inductive heating. In this manner it is achieved that during the inductive heating the temperature of the second metal holder and its contents lead with respect to that of the contents of the first metal holder. As a result of this the gas releasing material (6) releases its gas before the gettering metal begins to evaporate from the source (2, 21) of gettering metal. 
     The invention is suitable in particular for use in the manufacture of colour display tubes in which the gettering device is assembled in the tube before the window (12) and the cone (11) of the colour display tube are connected together by means of a sealing glass (18).

Abstract: Each piston head (38) has a diametrical dimension substantially less than the diametrical dimension of its respective bore (34) to provide a substantial annular space therebetween, and a solid seal-support ring (40) of low-friction material is expanded over each piston head and contracts into a circumferential groove (170) therein. Each ring groove is formed with a plurality of projections (176) which are spaced about and project outward from the bottom thereof. 
     Each piston (36) is thereby positively prevented from both rotary and longitudinal rubbing movement in its rings to thereby prevent the rings from wearing away the metal of the piston heads at the bottom and shoulders of their groove whereby both sealing and prevention of metal-to-metal contract between the piston heads and their respective bores is maintained by the rings.

Abstract: La chaleur sensible perdue (Q1) provenant de sources industrielles ou autres est augmentee jusqu'a atteindre des niveaux utiles de temperature en combinant au moins un cycle Rankine de production de vapeur avec au moins un cycle de pompe a chaleur en solution. La chaleur perdue est utilisee pour evaporer par ebullition le refrigerant dans l'evaporateur de cycle Rankine (10) pour fournir une source de vapeur a pression relativement elevee a un dispositif d'absorption (20) dans la pompe a chaleur a solution. Dans le dispositif d'absorption, la vapeur est mise en contact avec une solution de travail d'un absorbant et d'un refrigerant. Au fur et a mesure que la vapeur refrigerante est absorbee (en 22) dans la solution, ses chaleurs latentes de condensation et de solution sont degagees a une temperature superieure a la temperature de la source de chaleur perdue. La solution de travail est ensuite amenee avec un ecoulement commande vers un dispositif de desorption sous pression relativement basse (30) ou une partie du refrigerant est desorbee sous forme de vapeur provenant de la solution par addition de chaleur perdue supplementaire. La vapeur du refrigerant desorbee est ensuite condensee (40) puis pompee vers l'evaporateur pour etre reutilisee. La solution de travail est recyclee (par 38) a partir du dispositif de desorption vers le dispositif d'absorption pour etre reutilisee. L'utilisation de la source de chaleur perdue sensible est rentabilisee au maximum en extrayant des quantites successives de chaleur pour les utiliser dans la section de l'evaporateur a cycle Rankine et dans la section de desorption du cycle de pompe a chaleur. Des systemes a cycle multiples (Fig. 1b, 2a, 2b, 4a, 4b) augmentent la temperature d'une partie de la chaleur perdue jusqu'a des niveaux encore plus eleves.
