Title: Hot iron desulfurizing agent
Inventor: NISHIKAWA NORIO
IPC: C21C1/02
Filed: 1978-04-07
Abstract: PURPOSE:To provide a quick lime type hot iron desulfurizing agent with superior sulfurization action by mixing carbonates and hydroxides of Ca and Mg, carbon and quick lime in the form of powder. CONSTITUTION:Carbonates such as CaCO3 and MgCO3 with high decomposition points are mixed with hydroxides such as Ca(OH)2 and Mg(OH)2 with relatively low decomposition points in the form of powder so that the molar ratio becomes 0.4-2.0. 70-85 pts. wt. of the mixt. are mixed with 15-30 pts. wt. of carbon powder such as coke or graphite. 30-50 pts. wt. of the resulting mixt. are further blended with 50-70 pts. wt. of quick lime powder to obtain a hot iron desulfurizing agent. The carbonates and hydroxides decomposition release CO2 and steam in hot iron to facilitate contact of the hot iron to CaO by stirring, thus acceleating desulfurization. The carbon reacts with CO2, forming CO, which makes a reducing atmosphere necessary for desulfurization to enhance the desulfurization action of the agent.

Title: Vane rotary compressor
Inventor: YAMADA YOSHIKAZU
IPC: F04C18/344
Filed: 1979-04-05
Abstract: PURPOSE: To make prevention of oil compression for example by that of the flow of lubricating oil into a cylinder for example with an oil passage closed since a valve body for opening and closing the oil passage is shaped globular so that the passage resistance of lubricating oil may be reduced and the opening of the valve body may be set small.  
     CONSTITUTION: When a compressor has stopped, the pressure of a plunger hole 21 communicating to a pressure passage 18 becomes lower than that of an oil passage 23 communicating to an oil separating chamber so that a plunger 22 lowers. A steel ball 25 also lowers onto oil passage 23 side due to the difference of pressure between a oil passages 23 and 24 to cancel the communication between the passage 23 and 24 so that the flow of pressurized lubricating oil 16 into a vane groove 14 and a cylinder 26 is stopped by residual discharge pressure. Thereby, liquid compression is avoided on reoperation, and reverse rotation immediately after stoppage. Since valve body is globular, the passage resistance of lubricating oil is small. Therefore, the valve body whose opening can be set small is capable of quickly closing the passage 23.
