Title: Process for preparing a solution with a high specific volume activity of a protein with a tissue plasminogen activator activity(t-pa), solution containing the protein with t-pa activity and fibinolytic composition containing this solution
Inventor: PAQUES ERIC PAUL
IPC: A61L2/00
Filed: 1988-06-03
Granted: 1997-04-21
Abstract: On preparation of parenteral solutions for the treatment and prophylaxis of thromboses and embolisms to date it has been necessary, because of the poor solubility of t-PA, either to infuse very large volumes or else prepare a solution with a low volume and high t-PA concentration by adjusting to a low, non-physiological pH of 2 to 5. The invention therefore relates to a process for preparing a solution of high specific volume-based activity of a protein with plasminogen activator activity, achieving an increase in stability and solubility by adding at least two substances from the group of D-and/or L-amino acids, the salts, derivatives or homologues thereof, and to a process for pasteurising a protein solution with t-PA activity and to the use of this solution as fibrinolytic in human and veterinary medicine.

Title: Polyamide composition
Inventor: DEBETS WILHELMUS A M
IPC: C08L77/00
Filed: 1989-06-22
Granted: 1992-09-07
Abstract: Impact resistant polyamide compositions containing more than 45 wt.% polyamide and relatively minor amounts of an impact modifier. The impact modifier is an elastomer with groups that are reactive with respect to the polyamide. The impact modifier has an adverse effect on the high-temperature properties, which were already poor. According to the invention, compositions of polyamide, impact modifier and a copolymer of a vinylaromatic compound, in particular styrene, and maleic anhydride have improved high-temperature properties while maintaining good impact resistance.

Abstract: This is new thermoplastic resin. The manufacturing method comprises : 1)making graft copolymer (A) by grafting polybutadiene 40-70wt.%, aromatic vinyl monomer 20-60wt.% and unsaturated nitrile 10-40wt.%; 2)making copolymer(B) by prepolymerization monomer of styrene 40-80wt.% and acrylonitrile 20-60wt.% using polyfunctional organic peroxide and azo compd. as an initiator, and 2nd polymerization in pure water including an emulsion stabilizer; and 3)blending 30-70wt.% of (A) and 30-70wt.% of (B)

Title: Method and apparatus for using hazardous waste to form non-hazardous aggregate
Inventor: KENT JOHN M
IPC: F23J7/00
Filed: 1992-09-30
Granted: 1998-05-01
Abstract: Apparatus for converting hazardous waste into non-hazardous, non-leaching aggregate comprises means (10) for burning the hazardous waste to produce particulate solid materials, volatile gases and gaseous combustion by-products, oxidising means comprising at least one refractory-lined water-cooled, metal-walled vessel (26), means (76) for introducing the particulate solid materials, volatile gases and gaseous combustion by-products into the oxidising means (26), means (36,38) for inducing combustion in the oxidising means (26), the heat of combustion forming molten slag and non-combustible fines from non-combustible material. The slag (40) is accumulated at the bottom of the oxidising means (26). The non-combustible fines are accumulated in an accumulator (84) and introduced through conduits (102,103,105) into the molten slag to form a substantially molten mixture. An injector (117) is arranged to inject the non-combustible fines into the molten slag beneath its surface. The molten mixture is then removed into a slag box (108) and is cooled by cooling means (106) to form the non-hazardous aggregate.

Title: Method of producing polyester filaments
Inventor: SO JUN-O
IPC: D02J1/22
Filed: 1992-11-05
Granted: 1994-12-05
Abstract: A polyester filament having an irregular dim clolr, and a smooth feeling was manufactured. A low oriented undrawn yarn was spinned in a velocity of 1,000-1,500 m/min to give a low oriented yarn having a degree of orientation of 5-10 X 103. The low oriented yarn was drawn in the draw ratio of 2.8-3.2, at a heating roller of room temperature - 45 deg.C, heating plate of 160-200 deg.C to form various drawing point. Thereafter heat treated and confounded to give the filament.
