Abstract: A laser oscillation apparatus, comprising a laser beam emitting unit for emitting an excitation light, an optical resonance unit at least having a laser crystal and an output mirror, a nonlinear optical medium which is placed in the optical resonance unit and which generates a second harmonic from a fundamental wave oscillated by the laser crystal, and a driving means for driving the laser beam emitting unit, wherein the nonlinear optical medium is held by a nonlinear optical medium holder, and the nonlinear optical medium holder can be rotated with respect to axes of at least two directions crossing to an optical axis passing through the optical resonance unit.

Abstract: Locking cylinder, particularly an electronic locking cylinder and with electromechanical rotational blocking in which the electronic key (64) has facing electrical terminals (66) on blade (65), and the rotating core (2 or 3) of the cylinder has an external annular track (6) that is electrically conducting and with its internal face communicates with an electrical contact (5) supported on terminal (66); whereas the external annular track (6) is supported in the electrical brushes (7) of external (2) and internal (3) rotors; there is a first modular box (8) on the inside of a cast hollow part (1a) of external rotor (2) which box contains electrical brush (7), processing unit (31) and an electromechanical locking device, which incorporates a ball (19) and a vertical tumbler (16); as well as a second modular box (9) containing electrical brush (7) and the autonomous electrical source; the two modules are connected by the electrical conductor (10).

Abstract: Commercial sterilization of the interior surfaces of containers, cups or bottles by the use of energetic electrons is accomplished by directing electrons of moderate energies through the open mouth of such containers. Electrons which would normally illuminate the container beyond the inner diameter of the neck opening may be absorbed by a suitable electron-absorbing and cooled mask positioned above the container neck.

Abstract: The invention relates to a thermosetting coating composition for precoated steel sheets which are required to have high hardness, good workability and stain resistance, to a precoated steel sheet having a film of the coating composition, and to a method for producing such precoated steel sheets.

Abstract: A process of preparing alkali metal N-acyl amino acids, especially sodium N-acyl sarcosinates. The process of the invention eliminates the use of phosphorus trichloride or thionyl chloride and carboxylic acid chlorides. The process involves reacting the alkali metal N-acyl amino acid directly with a fatty acid at elevated temperatures with constant removal of water generated in the reaction.
