Filed: 1980-06-11
Abstract: PURPOSE: To suppress the strain in a gallery direction, prevent waving and simplify work by welding strain preventing pieces by tack welding to the upper part of the butt parts of longitudinal plates and gallery direction plates.  
     CONSTITUTION: Strain preventing pieces 4 are tack-welded 5 at every suitable interval to the upper part of the butt parts 3 of groove faces across longitudinal plates 1 and gallery direction plates 2 in a manner as to maintan the groove face gaps of the plates 1 and the plates 2 at the arrangment of bottom plates. Thence, the most of the groove faces of the plates 1 are automatically welded, and after the remaining part of the plates 1 are manually welded thereafter, the pieces 4 are removed, and the groove faces of the plates 1 and the plates 2 are automatically welded. By the above, the range of automatic welding is made long, the efficiency of work is made better; even more, the strain in the gallery direction is suppressed and the waves by the automatic welding in the longitudinal direction hardly appear.

Title: Body construction of rotary drill bit apparatus and nozzle device for excavating fluid
Inventor: EDEYUARUDO BAANETSUCHIEEGONZAR
IPC: E21B10/18
Filed: 1981-05-27
Abstract: A rotary drill bit for drilling a bore hole in the surface of the earth is provided in which the drill bit comprises a body having a duct therethrough for carrying drilling fluid. A conical cutting head having an axis at an acute angle with respect to the axis of the drill bit .is mounted in the cutting head. An elongated nozzle is positioned at the end of the duct for injecting the drilling fluid into the bore hole. The nozzle has an opening which opens into the bore hole wherein the longitudinal center line of the opening follows the locus of the mid-point between the side wall of the bore hole and the outermost circumference of the cutting head. Drilling fluid injected through the nozzle removes detritus from between the teeth and the cutting head at the bottom of the bore hole. The body of the drill bit has a first portion having a truncated conical surface with the axis of the truncated cone coinciding with the axis of the cutting head. The surface of the truncated cone is tangent to the side surface of the bore hole at a line on the opposite side of the body from the nozzle. This forms a passage between the surface of the truncated cone and the side surface of the bore hole for the upward flow of drilling fluid and detritus.
