摘要： A crucible holder made of a carbon material for use in crystal pulling operations and in the shape of a hollow receptacle. The holder includes at least two distinct and complementary parts that can be brought together by junction surfaces. When the parts are assembled to form the crucible holder, specific portions of the junction surfaces overlap to form at least one overlap area. The crucible holder can limit chemical reactions between the crucible and the holder and prolong the lives of both.

摘要： This invention relates to a process for identifying the external surface or surfaces of an Al alloy of a homogeneous or composite material by electrochemical means. This method involves forming an anodic layer, in situ, on the products to be identified, by electrolysis under predetermined conditions and following or plotting the development of the voltage U at the terminals of the electrolyzer as a function of time t during an intentiostatic test. The shape and relative position of curves U=f(t), thus obtained, allows the various alloys tested to be identified from a comparison of the derived curve from a curve U=f(t) derived from a known sample. The present method has advantages over the earlier methods of marking in that it provides: non-destructive method employable in situ on products which may have large dimensions (coils, plates, sheets, etc.); almost instantaneous identification; high reliability; and is simple and economic to use.

摘要： An apparatus for the anodic treatment of aluminum alloy pistons used in internal combustion engines. The apparatus comprises at least two members applied symmetrically to the lateral cylindrical surface of the piston which are connected to a source of positive direct current. An electrode connected to a source of negative direct current and having at least one aperture therein is positioned adjacent the head portion of the piston which is to be treated. A deflector of electrically insulating material disposed generally parallel to and spaced from the electrode and having a circumference curved toward the electrode is provided with a central passage therethrough which receives the head portion of the piston, with the head portion being disposed opposite the electrode. The deflector surface facing the electrode is provided with a flexible means for sealing the deflector to the head portion and a regulated flow of anodizing electrolyte is provided through the aperture in the electrode, in the direction of the deflector and the head portion. This apparatus can be applied to the high speed production of barrier coatings which are confined to the piston heads and which can prevent development of heat stresses which could adversely affect the satisfactory functioning of the piston. The coatings are produced without the use of masks or treatments other than the anodic treatment.
