Title: Pas teurizable freeze-driable hemoglobin-based blood substitute
Inventor: HSIA JEN-CHANG
IPC: A61L2/00
Filed: 1988-05-04
Granted: 1991-11-12
Abstract: The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood. Two classes of HemoSafe are derived respectively from animal-hemoglobin and human-hemoglobin. HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man. Both types of HemoSafe may be derived in the following manner. The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free. CO-HemoSafes are stable for 2 months at 56 DEG C in either the solution or the freeze-dried state. For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe. In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.

Granted: 1993-05-26
Abstract: The optical information recording medium,  which  can  record and reproduce   information   using   semiconductor   laser,   is characterized in that information is recorded by the reaction that separates the recording medium into halogen atom and gold with the temperature increase,  while  information  is  reproduced  by  the difference of reflectivity of  separated  part  and  non-separated part. The halogen atom for halogenated  gold  compound  is  chosen from Cl, Br or  I.  The  use  of  halogenated  gold  compound  can simplify the manufacturing process of optical recording medium and prevent S/N reduction.

Title: Hot dust recycling apparatus and method
Inventor: HERBERT MAYER
IPC: C21B13/14
Filed: 1991-12-24
Granted: 1999-09-01
Abstract: A process for recycling hot dust from a gasifier or melt-down gasifier by means of a hot gas cyclone separator integrated into a pipe system is described, together with the associated apparatus. The hot dust from the hot gas cyclone separator is supplied by means of a lock system to a burner in order to overcome the pressure difference between the hot gas cyclone separator and the melt-down gasifier. By means of the lock system the dust is supplied from a lower pressure zone to a higher pressure zone. The dust to be recycled comprises coke or a mixture of coke and iron particles.
