Title: A pregummed hanging material
IPC: C09J7/32
Filed: 1945-01-03
Abstract: The adhesive of pregummed hanging materials such as wallpapers comprises a dried coating of cereal flour, particularly rye or wheat flour, hydrolyzed, preferably by employment of an amylase, to a reducing sugars content, calculated as dextrose of 5-26 per cent of the dried coating, which adhesive has when diluted with water in the ratio of 1 part of solids to 10 parts of water a viscosity at 75 DEG F. of 15-750 cp.  The hydrolyzed flour may be associated with substances, e.g. sodium chloride, formate, acetate, nitrate or lactate, urea, glycerine, glucose, invert sugar, which, like the reducing sugars of the hydrolyzed flour, slow down the rate of drying and reduce the tendency of the coated sheet to curl, the total of such substances, including the reducing sugars, being not less than 10 per cent.

Abstract: 1531812 Pharmaceutical preparations ETAB ANI 8 Jan 1976 [8 Jan 1975] 688/76 Heading A5B [Also in Division C6] The mutant strain NCIB 11144 is derived from a Gram-negative bacterium isolated from the flora of the digestive tract of the leech Hirudo medicinalis by cultivating the isolated bacterium in a medium low in total nitrogen content but enriched in sulphurcontaining amino acids, for example an aqueous medium composed of peptone, methionine, cystine and sodium chloride for controlling the isotenicity. The specified sulphurcontaining amino acids may be partly or completely replaced by others e.g. glutathione, cysteine and homocysteine. Cultivation of the mutant strain in a nitrogen-containing medium which contains aminoniacal iron citrate and at least one phosphate, with part of the nitrogen of the culture medium being provided by human or non-human animal or vegetable tissue (see below) gives a product exhibiting biological activity towards animal or vegetable organs. The product which is present in the culture filtrate, gives a negative reaction to ninhydrin, positive reaction to biuret, produces a deep orange colouration when boiled in sulphuric acid and liquefies gelatine. The expression "animal tissue" includes amniotic fluid, whole blood and components such as the cells, serum, plasma and fibrin, as well as tissue taken from the muscles, glands and bones of the animal body. An Example is directed to the preparation of a "pancreas" product using ground defatted pigs pancreas in the culture medium, and its effect in combating hyperglycemia in human beings and rabbits.
