Title: Psychrophilic protease and psychrophilic bacteria
Inventor: TAMIYA EIICHI
IPC: C12P21/04
Filed: 1996-02-16
Abstract: A novel psychrophilic protease and a microorganism having the psychrophilic protease producing ability are disclosed. The protease acts on and decomposes casein and dimethylcasein but not on ribonuclease, has an optimal temperature of about 40 ~C. Under the condition of storage at pH 7 for 1 hour, it is inactivated scarcely at a temperature up to 30 ~C, but at 40 ~C it loses about 40 % of the activity. At 50 ~C, the protease is rapidly inactivated so that the activity is completely abolished in about 15 minutes. Flavobacterium balustinum having the protease producing ability is also disclosed.

Title: High-temperature composite materials with carbon or carbon-coated fibre reinforcements and enhanced oxidation resistance
Inventor: PAILLER RENE
IPC: C04B35/80
Filed: 1996-12-06
Abstract: The matrix of the composite material is made in sequenced manner by chemical vapor infiltration within fiber reinforcement. Each elementary sequence of the matrix comprises a relatively flexible layer and a relatively rigid ceramic layer, and the sequences are of thicknesses that increase going away from the reinforcing fibers, with the thickness at least of the first-deposited sequence being selected to be sufficiently small for the fibers to be coated in essentially individual manner. The flexible layers are made of an anisotropic material having sufficient capacity for elastic deformation in shear and transversely, and although a mainly ceramic character is conserved for the matrix, the thickness of the flexible layers is nevertheless selected to be sufficiently large to be capable of absorbing differential expansion of the components of the composite material while it is being made without inducing the existence of an initial network of cracks.
