Title: Systeme de traitement des levures comportant un acide amine charge negativement adjacent au site de traitement
Inventor: BJORN SOREN
IPC: C12N15/31
Filed: 1990-03-01
Abstract: Un polypeptide destiné à être produit en levure comprend une fusion d'un peptide signal, d'un peptide de tête et d'une protéine ou d'un polypeptide hétérologues. Le polypeptide est modifié dans sa séquence d'acides aminés ajdacente à un site de traitement de levure situé entre l'extrémité de terminaison C du peptide de tête et l'extrémité de terminaison N de la protéine hétérologue, de façon à fournir une présentation du site de traitement qui rend accessible celui-ci au clivage protéolytique. On assure une telle présentation en ajoutant un ou plusieurs acides aminés (dont au moins un est chargé négativement) soit à l'extrémité de terminaison C du peptide de tête soit à l'extrémité de terminaison N de la protéine, ou aux deux. La protéine hétérologue peut par exemple être constituée par un précurseur d'aprotinine ou d'insuline ou par un analogue de ce précurseur.

Title: Fabrication of cast articles from high melting temperature superalloy compositions
Inventor: DZUGAN ROBERT
IPC: B23K9/04
Filed: 1991-11-28
Abstract: A superalloy article is fabricated by casting a high melting temperature superalloy composition and then refurbishing the primary defects that are found in the surface of the cast piece. The article is refurbished by excising the primary defects and a surrounding portion of metal by grinding. filling the excised volume with metal of the same composition as the cast article by welding or a similar technique. smoothing the surface around any resulting filler metal defects, and applying a cladding powder to the surface from which the filler metal defects are removed. The cladding powder is applied by painting a binder onto the surface and then dusting cladding powder onto the binder before it has dried. The cladding powder is a mixture of particles of a high melting temperature superalloy and particles of a lower melting temperature metal. The article is heated to a preselected temperature, depending on the alloy, to melt and subsequently solidify the cladding powder. Finally, the article is hot isostatically pressed to achieve final closure of surface defects.
Patent CA-2056739-A1 (CA)
IPC: G01S7/03
Filed: 1991-11-29
Abstract: A  wideband,  frequency  synthesized,  fault-tolerant microwave signal generator is described, which can generate the  spectrally  pure  transmitter  or  antenna  drive  and receiver first local oscillator (LO)  signals needed for advanced tactical airborne radar systems.  Separate genera-tion of the transmitter drive (TD) and first LO minimizes spurious signal generation over a wide operating band, typically 45% or greater.   Extensive fault tolerance is provided without resort to redundant hardware.  The sharing of two internal signal generators limits the frequency generation needs to just the operating band for economy of required hardware.

Title: Method for separating a multi-component feed stream using distillation and a controlled freezing zone
Inventor: POTTS WILLIAM A JR
IPC: F25J3/02
Filed: 1992-01-09
Abstract: The invention relates to a method for separating two primary components of a multi-component feed stream (e.g., methane and nitrogen) in the presence of a third, freezable component (e.g., carbon dioxide) having a relative volatility less than that of either primary component.  The inventive process employs both a distillation section and a controlled freezing zone ("CFZ").          The freezable component is allowed to freeze in the CFZ, and the resulting solids are collected at the bottom of the CFZ.  The CFZ also produces a vapor overhead product enriched in one of the primary components and a liquid bottom product enriched in the other primary component.  The solids of the freezable component are melted and mixed with the CFZ liquid bottom product to form a liquid feed stream for the distillation section which operates like a conventional distillation section, while tolerating significantly high concentrations (i.e., >0.1 mole %) of the freezable component without solids formation, at temperatures well below the freezable component's freezing point.
Patent CA-2061151-A1 (CA)
Title: Treatment of gases
Inventor: WATSON RICHARD W
IPC: B01D53/52
Filed: 1992-02-13
Abstract: A gas stream comprising hydrogen sulphide is preheated in a heat exchanger 2. Part of its hydrogen sulphide content is burnt in a furnace 6 to form sulphur dioxide and Water vapor. Pure oxygen or oxygen-enriched air is used to support combustion. The sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapor and further water vapor. The sulphur vapor is removed from the gas stream in a condenser 14. The gas stream is then divided into first and second subsidiary streams. The hydrogen sulphide content of the first subsidiary stream is totally converted to sulphur dioxide in an incinerator 16 using pure oxygen or oxygen-enriched air to support its combustion. Water vapor is then removed from the first subsidiary stream in a condenser 20, and the resulting gas stream now relatively rich in sulphur dioxide, is recycled to the furnace 6. The second subsidiary stream is subjected to a plurality of stages 26 of catalytic reaction between hydrogen sulphide and sulphur dioxide to form further sulphur vapor which is removed therefrom.

Title: Treating material for animal excretions and method of producing the same
Inventor: FUJIURA YOJI
IPC: A01K1/015
Filed: 1992-04-28
Abstract: The invention relates to a treating material for animal excretions comprising agglomerates of a powdery or short-fiber-like excretion treating base material and fine powder of water-absorbent resin sprinkled on the agglomerates, and also to a method of producing a treating material for animal excretions which comprises forming agglomerates from a powdery or short-fiber-like excretion base treating material using water and then, sprinkling fine powder of a water-absorbent resin on the agglomerates. The treating material for animal excretions according to the invention can quickly absorb moisture, and its surface is brought to a half dry condition soon after it absorbs urine. Thus, it is possible to prevent urine from being attached to the pet's fur and paw, and contaminating the room or the like. Further, by absorbing urine, the treating material becomes a rubber-like mass.      Thus, only its portion having absorbed urine can be easily taken out and disposed. It is thus useful for treating excretions of pots or like animals.
