Patent CH-509171-A (CH)
Title: Low alkalinity binders for fast co2/silicate - moulds prodn
Inventor: JAMES ALEXANDER
IPC: B22C1/16
Filed: 1963-07-05
Abstract: Silica sand is coated with low-alkalinity sodium silicate and treated with NaOH to produce a dry free-flowing sand that requires a minimum time (1/2-3 mins) when gassed with CO2. The water of hydration is kept to 10-20% of the maximum, and the weight of coating is only 1-2% of the weight of sand. Gassing is done at a pressure of 0.035-0.15 kg/cm2 through a rubber sheet with holes in it, and vented through holes in the pattern and bottom plate. By the use of a low alkalinity binder, the mould is easier to release from the pattern and the reduced gassing time allows greater productivity from one pattern. Temperature rise on gassing is no more than 5 degrees and the mould has good shelf life and stability before casting.

Abstract: Novel processes and novel industrial unicellular micro- organism strains, in particular industrial Bacillus strains, are provided for the increased production of endogenous and exogenous polypeptides. Cloning vehicles which contain one or more copies of the gene which expresses the polypeptide of interest are introduced into a compatible host, the transformed host organisms are treated in order to form protoplasts and are then fused with protoplast acceptors which are prepared from industrial strains. This results in an efficient transfer of the vehicle which contains the genes of interest, such that the modified industrial strains which are obtained are efficient for producing the desired polypeptide product.
