A jewelry mandrel having a tapered shaft with an axial groove in the surface of the shaft. The axial groove is capable of accepting one end of a metal wire at a pre-selected location and the depth and width of the groove arc sized, such that the metal wire is not generally displaced axially from the pre-selected location as the wire is wound around the perimeter of a cross-section of the shaft.

L'invention est relative à un ensemble d'injection de carburant à l'intérieur d'une chambre de combustion de turbomachine, monté sur la paroi (1-2) délimitant ladite chambre et comprenant un bol de prévaporisation (7) monté flottant par rapport à ladite paroi, parallèlement à une direction déterminée. Une partie (7e) d'une structure solidaire du bol de prévaporisation (7) et une partie (5b) solidaire (3-4-5) de la paroi (1-2) de la chambre de combustion sont alignées sensiblement parallèlement à ladite direction déterminée et sont susceptibles d'être disposées à une distance variable l'une de l'autre, et cependant qu'un aimant (15) est fixé sur l'une (5b) desdites parties et est apte à coopérer avec l'autre partie (7e) pour s'y fixer ou au contraire s'en détacher, maintenant en position ou, au contraire, laissant libre de flotter le bol de prévaporisation par rapport à la chambre de combustion. Une application est la réalisation d'une turbomachine ayant un montage aisé.

The present invention generally relates to cryogenic refrigerator and more particularly, the cryogenic refrigerator compressor assembly procedure and to means for supporting piston for use in such a cryogenic refrigerator. This invention solves the above-mentioned drawbacks by avoiding the radial movements of the piston. An object of this invention is the assembly procedure of a cooler compressor comprising the following steps:
At least one piston is coated by a material, Each piston is placed in the cylinder, The temperature is raised up until a predetermined temperature so as the piston and/or its coat expanse to occupy all the cylinder, Each piston is fixed in the cylinder in this position, The temperature returns to ambient temperature.
Another object of this invention is the cooler compressor piston spring comprising two flexure bearings separated by a gap connected together by a first and a outer rings.

Form the oval rings 25 from the circular rings 23. Then, twist the oval rings 25, for instance three times, around center of the longitudinal direction, and create the ring portion for male 31 and the binding portion at the both side of the binding portion. After that, obtain the rings for male 2 and the rings for female 3 by cutting the binding portion.
