Title: Laser device utilizing hollow cathode  segments of specific lengths and diameters
Inventor: WANG SHING C
IPC: H01S3/03
Filed: 1979-09-18
Granted: 1982-08-10
Abstract: LASER DEVICE UTILIZING HOLLOW CATHODE SEGMENTS OF SPECIFIC LENGTHS AND DIAMETERS                  ABSTRACT OF THE DISCLOSURE         A laser device for generating multiline emmissions when appropriately energized.  The device consists of two major components, an anode-cathode assembly and, in a first embodiment, an adjustable brewster end section or in a second embodiment, an integral mirror end section.  The anode-cathode assembly comprises one center located short cylindrical anode and two segmented cylindrical hollow cathodes located symmetrically on each side of the anode, the inner diameter of the hollow cathodes being selected depending on the particular laser transition involved and particular output level required, the length of each cathode also being selected to adjust the gain of the selected laser transition.  The anode and cathode are electrically insulated by a cylindrical metal ceramic seal.  The outer surface of the cathode is covered with quartz insulating sleeves to prevent electrical discharge from the outer cathode sur-face and to encourage effective inner cathode discharge.          The cathode is thermally connected to the external envi-ronment through a structure  coupled to the cathode and the laser tube envelope thus allowing heat generated within the cathode due to the electrical discharge to be effectively dissipated away thereby allowing higher input power load into the cathode for selected lasing action which requires a relatively high excitation input.  A metal vapor reservoir may be provided and is preferably attached to the anode section for metal vapor laser operation.

Abstract: L'invention concerne un dispositif de réglage de l'alignement et de la distance intercalaire de deux abouts de rails pour le raccordement de ces deux abouts par éclissage ou par soudure et éventuellement d'ébavurage de la soudure formée. Ce dispositif comprend un bâti horizontal rigide à structure ouverte apte à chevaucher les deux rails en ménageant autour des deux abouts à raccorder une zone d'accès délimitée par la structure ouverte du bâti, ainsi que deux presses primaires et deux presses secondaires montées alignées sur le bâti et disposées de manière telle que les deux presses primaires se trouvent entre les deux presses secondaires et que chaque ensemble formé par une presse primaire et une presse secondaire puisse enserrer l'un des deux rails à raccorder. Un ensemble escamotable de réglage de distance intercalaire et d'ébavurage est porté par le bâti et est déplaçable entre une position de repos où il est en appui sur le bâti et une position de travail où il se trouve dans la zone d'accès du bâti, cet ensemble escamotable étant conçu pour réaliser un réglage de distance intercalaire avant l'opération de raccordement et pour éliminer le bourrelet de soudure après l'opération de raccordement, dans le cas où celle-ci est réalisée par soudure. Le dispositif selon l'invention est caractérisé par le fait que chaque presse secondaire est déplaçable verticalement par rapport au bâti sous l'action d'un vérin et que deux butées d'appui réglables verticalement, aptes à coopérer avec le dessus du champignon du rail, sont prévues respectivement entre chacune des deux presses primaires et la presse secondaire qui lui est associée.

Abstract: ABSTRACT      The invention relates to a novel attachment means useful in fixedly interconnecting polygonal drill steel to a rock bolt dolly when the drill steel is inserted into complementary socket means provided at one end of the dolly.          Heretofore, accidental disengagement of the drill steel from the dolly was relatively common often resulting in injury to workers and lost operating time.  When in their socketed mode, a length of mild steel rod is welded along one of its end portions to the rock bolt dolly and the other end portion is tightly wound about the drill steel so that this winding abuts a collar on the drill steel intermediate the rock bolt dolly and the winding when the drill steel is socketed to the dolly.
