Title: Spray nozzle equipped with nozzle orifice molding capacity
Inventor: YAN FURITSUTSU
IPC: B05B1/00
Filed: 1982-02-09
Abstract: PURPOSE:To rapidly respond to the lowering in the capacity of a spray nozzle generated by erosion or corrosion, by providing a mechanism for compensating the consumption of a nozzle orifice part. CONSTITUTION:A spray nozzle is formed by attaching an orifice molding body 5 to a nozzle main body 4 while a thin walled pipe 1 is inserted through both of them while and a pushing-in body 3 equipped with a pushing-in mechanism 2 is further provided to one end of the thin walled pipe 1. The spray state of a fluid from an orifice A is affected by erosion and corrosion due to the fluid and the area of the orifice A is gradually increased. In order to prevent this phenomenon, the pushing-in mechanism 3 is operated to push the thin walled pipe 1 into the orifice molding body 5 and the area of the orifice A is reduced to obtain a normal spray state.

Abstract: PROBLEM TO BE SOLVED: To stably weight an accurate volume of molten metal supply by detecting a weight of a molten metal supplying ladle and a molten metal being taken in it, which are hung down with a hang down means, by a weight detecting means installed at a top end of a molten metal supply ladle tumbling over/transfer arm and, by releasing an engagement of the hang down means after depositing it to a fastening means. SOLUTION: When a molten metal is poured into a mold cavity, the metal is supplied to an injection sleeve via a molten metal supplying ladle 90. A switch valve 120a is opened for sucking a gas inside the metal supplying ladle 90 so as to take a molten metal M in a retention furnace F into the metal supplying ladle 90. In accordance with a signal emitted by a weight detecting means 210 when it is detected that a given volume is taken in, the ladle 90 is fastened by a fastening means 80. After then, the ladle 90 is tumbled for cutting the metal, while it is pulled up by a transfer arm 200, and is transferred thereafter.  In this case, an air cylinder 82 of the fastening means 80 is driven so as to release an engagement of the hang down means 60 and fasten the molten metal supplying ladle 90, after depositing the weight of the ladle 90 and the molten metal inside the ladle to the fastening means 80.

Title: Engine with reservoir chamber
Inventor: NISHIMURA HIROBUMI
IPC: F02B23/00
Filed: 1982-02-08
Abstract: PURPOSE:To reduce the mechanical loss of a valve moving mechanism and the engine output loss during a low load operation without imparing the gas sealing function into a reservoir chamber by providing a correction device reducing the spring force energizing a reservoir chamber opening/closing valve in the closing direction during a low load operation of an engine. CONSTITUTION:When an engine is in a low load condition, the compression ratio in a compression stroke is comparatively low, thereby the gas pressure in a reservoir chamber 17 is decreased, a control valve 29 is opened by a control circuit 30 after receiving the signal of a detector 31 detecting the low load condition, the pressure in an oil hydraulic chamber 24a is reduced, and a piston member 25 is moved in the contracting direction. Accordingly, the initial spring  length of a valve spring 23 is increased, thus reducing the spring force. However,  since the pressure of the reservoir gas in the reservoir chamber 17 is comparatively low, a valve 19 can be reliably held at a closed state by surpassing the gas pressure even if the spring 23 force is reduced, thus no gas is allowed to  leak into a combustion chamber 6.

Title: Burner nozzle for flame-spraying pulverized material
Inventor: SUWA TOSHIO
IPC: B05B7/20
Filed: 1979-02-21
Abstract: PURPOSE: To flame-spary a pulverized material at a high deposition efficiency by providing in a cross-sectionally circular premixing combustion chamber two steps of combustion-supporting-gas feeding inlet ports, i.e. tangentially extended feeding inlet ports and an axially extended feeding inlet port directed toward a flame ejection port.  
     CONSTITUTION: Oxygen gas is supplied into a premixing combustion chamber 15 through a combustion-supporting-gas guide port 16 and combustion-supporting-gas feeding inlet ports 17a, 17b, 17c so as to be mixed with a gaseous-solid mass (for example, a mixture of Al 2 O 3  and C 3 H 3 ) supplied into the chamber 15 through a feeding inlet port 14. Since the feeding inlet ports 17a, 17b, 17c are provided in different positions with respect to the axis of the chamber 15, the gaseous-solid mass is mixed initially with the combustion supporting gas ejected from the feeding inlet port 17a, and thereafter with the combustion supporting gas ejected from the feeding inlet ports 17b, 17c. Thus, the combustion supporting gas is mixed perfectly with the gaseous-solid mass to form a flame zone of a high temperature extended from the interior of the chamber 15 to the outside of a flame ejection port 15a. Accordingly, even when the pulverized material in the gaseous-solid mass has a high melting point, it is melted perfectly in every part of the mentioned flame zone so that the pulverized material can be deposited on a base metal at a high deposition efficiency.
