Title: Lime blowing system for converter - charging tank to preceding blow pressure during cold blast
Inventor: EICHINGER FRITHJOF
IPC: C21C5/34
Filed: 1973-06-01
Abstract: Lime is charged to an oxygen blowing converter from a pressurised tank which can be connected with its upper part to an oxygen source. During the converter tilting operation, when cold air is blown through the nozzles, the pressurised tank is recharged with oxygen. The oxygen pressure is automatically regualted to be equal to that which existed during the preceding blowing process. This saves the delay in lime charging operation caused by the build-up if the pressurised tank is recharged after the cool air blowing cycle.

Title: Temp. regulator for heating or cooling plant compressor - has throttle valve in feed duct, and separator openings, for liquid feed
Inventor: GLAS LARS-OLOF ALBERT HILDING
IPC: F25B43/00
Filed: 1974-01-18
Abstract: Regulator for the operating temp. of a compressor for a heating or cooling plant has a liq. separator in the duct between the evaporator and the compressor suction side, for unevaporated medium; the vapour inle to the compressor is normally above the liquid level for the medium in the separator. The feed duct before the evaporator contains a throttle valve whose ability to pass liquid medium can be varried in dependence on the compressor operating temperature, to increase as the temp. increases and vice versa. The separator contains inlet opening(s) in the region of the liquid level and connected to the compressor suction side, so that liquid medium passes to the compressor and reduces its operating temperature when there is a rise of the liquid level due to increased feed of liquid medium to the separator. Impermissible rise of the compressor operating temperature is reliably prevented, even when operating with low evaporation temps.
