Title: Zirconium appts - permitting discharge of magnesium chloride
IPC: C22B34/14
Filed: 1971-02-22
Abstract: The reaction vessel to which ZrCl4 is admitted is surrounded by an outer vessel providing an annular space into which by-product MgCl2 is initially transferred and from where it is them discharged. Pref. transfer is by siphon, the entry having a device filled wtih MgCl2 to prevent egress of Mg, and having also a shield to prevent access of Zr descending through the melt. The siphon may have its outlet above its inlet, both being so located that when the Mg metal level is above the highest point of the siphon the inlet is immersed in MgCl2, while the outlet is so placed that MgCl2 does not escape before the Mg level reaches the inlet.

Title: Continuous heat-treatment of cold-rolled steel strip - two-stage process for mass prodn of deep-drawing steel
IPC: C21D9/54
Filed: 1973-04-27
Abstract: The strip travels through shears and/or uncoilers to second set of shears and then to a welding unit to make continuous strip, which goes through electrolytic cleaning. After cleaning, the strip is fed over rollers on two moving trolleys; the length of these loops is adjustbale so that, even when the flow of strip is halted by the welding operation, it can still be fed continuously through a furnace where it is held for 20-30 seconds at 700-720 degrees C. The strip then enters a chamber, filled with non-oxidising gas, contg. flying shears and coilers for hot-coiling, the temp. of this chamber being held constant. The coils are then fed through a second furnace on trolleys wehre they remain 1 1/2 -2 hrs. to permit adequate grain growth, and they pass into a cooling zone for cooling through the critical temp. range. The next stage comprises a second chamber, filled with a non-oxidising atmos., where the rolls of strip are uncoiled and pass through shears and a welder to reform the continuous strip, which then travels through a press. spray cooler to a cold-rolling unit, shears and a coiler.

Title: Supply circuit for a pump - uses semiconductors to chop inputs to regulate pump cycle
IPC: H02K33/02
Filed: 1974-01-24
Abstract: This circuit operates a pump that has a piston made from magnetic material sliding inside a cylinder. Movement in one direction is caused by the magnetic field of a coil around the cylinder and movement in the reverse direction by a spring. The operating circuit chops the alternating supply into suitable periods for the required pump cycle. The chopping is achieved either by a triggered thyristor or by a unijunction transistor. The chopping rate may be made dependent upon temperature by using a thermistor and a sensing amplifier to operate the trip circuit.
