摘要： A safety device for vessels of compressed gases is disclosed which comprises a cap enclosing the valve of the vessel, a port formed in the wall of the cap for passing a nozzle attached to the valve, a handling member for rotating the handle of the valve from outside of the cap, a purge gas introducing and exhausting ports formed in the wall of the cap, and a detector disposed in the middle of the exhausting pipe coupled to the purge gas exhausting port. The handling member comprises a shaft vertically extending through and slidably supported by the ceiling of the cap, a horizontal disk secured to the lower end of the shaft, and four circumferentially equally spaced vertically extending fingers fixedly secured to the circumferential portion of the lower surface of the disk, which disengagably engage with the grooves formed on the circumference of the handle. The cap is divided into bell-shaped upper half and hollow cylindrical lower half which abut at a horizontal plane passing through the axis of the port for the nozzle letting out the gas from the valve. Alternatively, the fingers may be bent inwardly and rotatably secured to the horizontal disk of the handling member. In this case, the inwardly bent portions of the fingers are held together by an annular clip to engage the straight portions of the fingers with the grooves of the handle of the valve, and the cap is divided into right and left symmetric halves which are detachably coupled together at a vertical plane passing through the axis of the cap.

摘要： An air-cooled cooling apparatus for cooling a cooling liquid within a cooling pipe of a refrigeration machine comprising a cooling cycle including a coolant compressor, an air-cooled condenser, an expansion valve, and a cooler, thereby cooling liquid of the refrigeration machine. The apparatus also comprises an air-cooled heat exchanger, outdoor-temperature sensors and three-way valves for controlling the flow of the cooling liquid to be cooled. When the outdoor temperature is high, the cooling liquid is supplied to the cooler, and when the outdoor temperature is low, the compressor is shut down and the cooling liquid is isolated from the cooler and supplied to the heat exchanger to be cooled by cold outdoor air.
