Abstract: ABSTRACT Acidophilic and acidoduric streptomycetes strains have been found to produce carbohydrases. These Streptomyces effectively elabo-rate glucose isomerase under acid conditions typically unfavorable for growth of conventional glucose isomerase producing Streptomyces. Sterilization of the culture and production media may be avoided by selectively propagating newly discovered Streptomyces acidodurans under acidic conditions which will effectively eliminate contaminating micro-organisms. The Streptomyces acidodurane herein also have the ability to undergo cultivation and elaborate glucose isomerase over a relatively broad pH range. Constitutive streptomycetes strains have also been isolated. Glucose isomerases derived from these Streptomyces strains are particularly effective for isomerizing glucose syrups to fructose-containing syrups.

Abstract: Abstract Purifi¢ation of hydrogen A moist hydrogen stream is dried by cooling to below the dewpoint of water and separating water, drying further over a regenerable solid absorbent, separating a part stream of dried gas and using it to regenerate water-loaded absorbent, and re-cycling the resulting moist regeneration gas stream into the moist hydrogen stream upstream of the water separation step.  If the starting moist hydrogen stream is produced by shift, CO2-removal and methanation the recycled gas is preferably introduced between CO2 removal and methanation.  If it is produced from unreacted methanol synthesis gas the recycled gas is preferably introduced upstream of methanol synthesis.          A moist hydrogen stream in which carbon oxides have been made innocuous by methanation over catalyst 18 is cooled to below dewpoint at 20 and depleted of water in separator 22.  It is dried in one of driers 28 and compressed at 32.  From compressor 32 a part stream is taken at 35, heated at 40 and passed through a further, water-loaded drier 28 to regenerate its charge.  The re-sulting moist gas is recyoled to the inlet of methanation catalyst 18.

Abstract: Abstract A shaped article containing a polymer which is capable of exhibiting anisotropy in the melt characterised in that the ratio of the stiffness in any two directions at right angles in the shaped article differs by at least 10%, and preferably by at least 50%, from the ratio in the same two directions for a control sample made from a melt consisting entirely of the polymer in anisotropic form, and wherein there is present in the shaped article at least 10% by volume of an inert filler in the form of voids.  These may be obtained by a variety of methods including disturbing the normal flow pattern of flow into a mould by including obstacles to flow in the mould, disturbing the pattern of flow by foaming in the mould, by using polymers capable of existing as a bi-phase anisotropic and isotropic melt and forming shaped articles in which this two-phase disposition is retained.

Abstract: ABSTRACT OF THE DISCLOSURE   A gas switching device for use with a gas supply system in which two gases, for example, oxygen and air are suplied to a medical unit comprises a manifold 106 to which are attached two identical valve assemblies 108, 110. The manifold has a first inlet 1 and outlet 5 for the passage therethrough of the oxygen and a second inlet 2 and outlet 6 for the air.  Each valve assembly 108, 110 includes a spool valve 122 movable from a first to a second position under the influence of the pressure of its associated gas.  At least one valve assembly 110 has an inlet 18' communicating with a passageway 15 in the manifoldwhich, in turn, communicates with the inlet 1 for the oxygen and an outlet 22 communicating with a further passageway 16 in the manifold which in turn communicates with the outlet 6 in the manifold for the air.  Should the air pressure drop below a predetermined value then spool valve 122 will move to its second position thereby permitting the passage of oxygen from inlet 18' to the outlet 22 in the valve assembly 110 so that oxygen exits from both outlet 5 and outlet 6.
