Abstract:
The present invention provides photosensitive compositions of high sensitivity comprising a photosensitive furylacrylylcontaining polymer having a polymerization degree of 500 or more wherein the furylacrylyl group is the photosensitive component of said polymer and wherein said furylacrylyl-containing polymer has been produced by the aqueous alkaline process. The photosensitive compositions are preferably mixtures of a photosensitive polymer and a sensitizer and/or other polymers.
Abstract:
Glucose in a glucose syrup is transformed into fructose, in high yields, by reaction with glucose isomerizing enzyme derived from micro-organisms which are characterized as having the ability to assimilate xylan to produce a glucose isomerizing enzyme.
Abstract:
A differential ring laser comprising a disc on which a ring laser, an interferometer and a phototube are fixed. A second disc is arranged coaxially with the disc, under the same and provided with the same ring laser, interferometer and phototube as the disc. Means are provided for independently rotating the two discs and there is a counter for counting the difference between the number of beat waves detected by the phototubes on the two discs.
Abstract:
A SMALL AMOUNT OF STRONG ACETIC ACID REACTS WITH MAGNESIA OR MAGNESIUM HYDROXIDE TO FORM STRONLY COHERENT POROUS GRAINS OR PELLETS WHICH, AFTER BEING MOISTENED WITH A SMALL AMOUNT OF WATER, CAN BE SHAPED WITH OR WITHOUT ADDITION OF REFRACTORY FILLERS AND FIRED INTO POROUS MAGNESIA BODIES. A SLURRY PREPARED FROM MAGNESIA OF MAGNESIUM HYDROXIDE, ACETIC ACID, A SMALL AMOUNT OF WATER AND CHEMICAL FOAMING AGENT SOLIDFIES WITHIN A FEW MINUTES INTO A POROUS BODY WHICH CAN BE FIRED TO PRODUCE MAGNESIA BRICKS LIGHTER THAN WATER.
