Title: Frame for drawers of any height - has support rails which swivel away transversely to insert direction when contacted
IPC: B65G1/08
Filed: 1974-12-30
Abstract: The support rails are attached to the frame in the manner of pivots so that they can swivel about an axis of rotation which is parallel to the direction in which the drawer is inserted into the frame whilst stops are provided to restrict the rotation of the support rail in one or other direction. In this way when a drawer which is higher than the spacing between two support rails is inserted into the frame the side edges of the drawer contact the inclined parts of the support rails above, which pivot and move away transversely to the inset direction of the drawer so as not to restrict the movement of the latter. On removing the drawer the support rails automatically fall back under gravity into their original supporting position.

Title: Guide and support roll for continuous casting plant - contg. minute surface discontinuities for releasing stress occurring in use
Inventor: DURINCK RENE
IPC: B22D11/128
Filed: 1975-10-31
Abstract: Guide and support roll wih a smooth surface for continuous casting plant, the novelty being that the surface contains grooves completely filled with a materail but leaving surface discontinuities in the roll to release stresses near the roll surface. The roll pref. contains helical groove(s) in which a profile with the same cross-section as the groove(s) is located, the ends of the profile(s) being fixed to the roll beyond its working surface. Alternatively, the grooves may be filled with a metallic agglomerate with feeble adhesion to the groove walls. A further alternative is that the grooves are closed with metal applied by deposition welding to form a longitudinal fissure in the deposit and to leave a space between the deposit and the base of the groove(s). The profile(s) may be hot rolled into groove(s), folowed by machining the roll surface; and the agglomerate can be obtd. by metal spraying, but avoiding good adhesion to the groove walls. The roll surface is provided wtih artificial "fissures" permitting the surface to expand and contract under the thermal stresses etc. involved during casting, and thus preventing the formation of real fissures resulting in roll fracture.

Title: Recovery of magnesium from hot gas mixts. with carbon monoxide - by contacting the gas stream with a molten aluminium magnesium alloy to condense and absorb the gaseous magnesium
IPC: C22B26/22
Filed: 1977-06-23
Abstract: Magnesium is recovered from a hot gaseous mixt. of Mg and Co (such as the prod. stream resulting from the redn. of MgO with carbon at >1000 degrees C), by rapidly cooling the gas in contact with a molten aluminium-magnesium alloy which simultaneously dissolves the Mg. Pref. the alloy contains >=25 wt.% esp. 30-70 wt.% Mg so that the m. pt. is as low as possible (e.g. the alloy contg. 35% Mg is fully molten at 450 degrees C). Recovery of Mg is increased if the alloy has the biggest possible surface area, which is achieved e.g. by spraying the molten alloy into the hot gas stream in the form of droplets. Process gives good recovery of Mg before it recombines with the CO to form MgO+C. The use of Mg/Al alloy is an improvement on the molten Pb or Sn previously used, since it avoids the necessity of recovering Mg from the Mg/Pb or Mg/Sn alloys, which themselves have little commercial application. The Mg is easily recovered from the Mg/Al alloy e.g. by distn.
