Title: A process for the production of malt enzymes
IPC: C12N9/24
Filed: 1937-02-24
Abstract: The liquid separating out above a settled malt mash is treated with adsorbing-agents, which are then separated and treated with an extracting-agent such as ammonia or other alkalies or salts of weak acids, e.g. sodium acetate, to obtain a diastatic extract which may be evaporated in vacuo.  The adsorbing-agent may be stirred in as a fine powder or used as a filter bed through which the liquid is filtered.  As adsorbing-agents silica gel, animal charcoal, colloidal metal hydroxides and aluminium silicates of the montmorillonite type, e.g. bentonite, bleaching or fuller's earth, may be used.  These aluminium silicates may be activated as by heat (500 to 800 DEG  C.), or by acid or electrical treatment.  In treatment with acids, they may be treated with strong mineral acid until almost all the soluble bases have been removed.  The treated liquid may be returned to the mash for use in the production of beer, as besides the enzymes, various undesirable constituents are removed by the adsorbent.ALSO:The liquid separating out above a settled malt mash is filtered through a bed of silica gel, animal charcoal, colloidal metal hydroxide or aluminium silicate of the montmorillonite type, e.g. bentonite, bleaching or fuller's earth.

Title: Improvements in and relating to aniline black
IPC: D06P1/32
Filed: 1931-02-23
Abstract: Aniline-black dyeing is improved by the addition to the customary liquors, or printing colours, containing aniline or other aromatic amine or aminophenol, of heterocyclic nitrogen bases, homologues, or derivatives thereof; phenols (other than aminophenols) may also be added.  As a further protection to the fibre, substances described as buffer substances, and consisting of substances which are more readily attacked by acids and oxidizing agents than the fibres, such as thickening agents and organic and inorganic basic or readily oxidizable compounds may be added.  The presence of non-volatile acids such as oxalic, tartaric and lactic, in addition to those usually employed, is desirable.  According to examples a padding black of aniline salt, potassium ferrocyanide and sodium chlorate has added to it (1) gum-water, p-phenylene diamine and quinoline; (2) ammonium thiocyanate and phenyl-hydrazine; (3) hydrolysed casein and ammonium thiocyanate; (4) resorcinol and formaldehydesulphoxylate; and (5) aniline oil is mixed with hydrochloric and acetic acid, potassium ferrocyanide, sodium chlorate, gum-water, p-phenylene diamine, quinoline, hydrolysed casein, tartaric acid and resorcinol. Yarns or fabrics are padded or printed in the customary manner. Further examples of the buffer substances are thickening agents such as glucose, dextrine, soluble starch, pectives, tragacanth, glue and their decomposition products, and the lower oxidation stages of sulphur, arsenic and phosphorous, and hydrazine, alcohols and their derivatives.
