Title: Method for the isolation and expression of a gene which codes for streptokinase, nucleotide sequence obtained, recombinant dna and transformed microorganisms
Inventor: GARCIA MARIO P E
IPC: C12N15/81
Filed: 1991-06-05
Abstract: The present invention relates to the field of biotechnology and genetic engineering and in particular a novel nucleotide sequence which codes for a streptokinase, as well as the recombinant DNA obtained therefrom which is used for the transformation of various host organisms. The technical object which is pursued with the proposed solution is to produce the protein in commercially useful quantities, by the recombinant method, with the possibility of alternatively using different hosts to obtain a high-quality streptokinase capable of being used as a thrombolytic agent in the treatment of different disorders. The present invention is based on the isolation of a new gene which codes for streptokinase from Streptococcus equisimilis of type C (strain ATCC-9542) and the cloning and expression thereof in prokaryotic (E. coli) and eukaryotic (Pichia pastoris) hosts, for which is includes the vehicles of expression which contain the genetic sequences of said gene, as well as the microorganisms transformed with these vectors capable of producing streptokinase. The protein obtained thereby can be used in clinical medicine as a therapeutic agent, in the treatment of disorders such as thromboembolic obstructions including coronary thrombosis.

Title: Non-rotating grinding apparatus
IPC: B23Q9/00
Filed: 1991-06-17
Abstract: A grinding apparatus is housed in a casing (24). The grinding machine (3) with its grinding pin (15) is journalled in a rotat-able attachment (2) such as to be imparted a rocking motion. The apparatus is carried by a pair of arms (7) which are freely mov-able in a generally horizontal plane, the one arm (9) being mounted for vertical movement on a stand (6). This vertical move-ment can be adjusted to produce a balanced effect and to deliver a downwardly acting force, feed pressure. Both the balancing and the feed pressure are achieved with the aid of one single piston-cylinder device (11).

IPC: G06F12/0831
Filed: 1991-09-12
Abstract: A shared memory multiprocessor having a packet switched bus, together with write back caches for connecting individual processors to that bus, employs a consitency protocol that permits the caches to store multiple copies of read/write data at identical physical addresses for use as neded by the respective processors. The protocol causes the hardware to automatically and transparently maintain the consistency of this data. To that end, the caches detect when a datum becomes shared by monitoring the traffic on the bus, thereby enabling them to broadcast an updating write on the bus whenever their respective processors issue a write to a shared address. If desired, this protocol may be extended to include an advisory invalidate for reducing the amount of address sharing that occurs, thereby enhancing the efficiency of the protocol. The protocol maintains a consistent view of memory for the processors, while permitting I/O devices to have direct access to the memory system.

Title: Inductive x-ray tube high voltage transient suppression
Inventor: WIRTH WILLIAM F
IPC: H05G1/08
Filed: 1991-11-28
Abstract: ABSTRACT     An X-ray imaging system includes an vacuum tube, which is biased by a high voltage power supply connected to the tube by two shielded cables.  The cables collectively have a plurality of conductors which are coupled at one end to the high voltage power supply.  The other end of each conductor is coupled to a component of the vacuum tube by a separate inductor.  During a voltage breakdown of the vacuum tube, the inductors depress electrical current flow between the anode and the cathode of the tube to reduce the erosion of tube components which results from the discharge.  This current is in part due to the energy stored in the cable, which is not depressed by conventional current limiting circuits in the high voltage power supply.  Voltage limiting devices connected to the tube prevent ringing in the cables from generating excessively high voltage levels.

Title: Reagent and methods for calcium determination
Inventor: DENNEY JERRY W
IPC: G01N33/84
Filed: 1991-10-10
Abstract: ABSTRACT A single, stable reagent and automatable methods utilizing the reagent for the assay of calcium in serum and aqueous samples, such as urine.  (Aqueous samples contain little or no protein.)  The reagent includes arsenazo III, 8-hydroxyquinoline, a buffer that does not bind calcium competitively with arsenazo III and that provides a reagent pH from about 8 . 5 to about 10, the buffer being in sufficient amount to maintain pH within +/-0.1 pH units of the reagent pH when the regent is added to a sample of unknown calcium content, dimethyl-sulfoxide and water.  Importantly, dimethylsulfoxide permits the incorporation of 8-hydroxyquinoline into a single, stable reagent, which is at an alkaline pH that is optimal for calcium measurement by the calcium--arsenazo III complex.  8-Hydroxyquinoline eliminates assay interference due to magnesium ion.  Also, at least one non-ionic surfactant in sufficient amount to minimize lipid turbidity may be added to the reagent.  Spectral hemolysis, and bilirubinemia.  Spectral interference from lipemia and hemolysis is further reduced by employing bichromatic measurements of the calcium-arsenazo III complex and by employing serum blank measurements.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for preparing purified ribonuclease dimers is provided which comprise the steps of dimerizing monomeric ribonuclease with a suberimidate coupling reagent, filtering out undimerized monomers and oligomers from the dimer solution using a series of ion exchange resin chromatography steps, monitoring the progress of the reaction through gel electrophoresis, and collecting the purified ribonuclease dimer product.  The method is advantageous in that large amounts of the dimeric product can be obtained efficiently and relatively inexpensively, and the ribonuclease dimers so produced can be employed for their beneficial effects in combatting viral and bacterial infections without the cytoxic effects normally associated with the ribonuclease monomer.

Title: Gas fires

IPC: F24C3/00
Filed: 1992-07-13
Abstract: ABSTRACT          IMPROVEMENTS RELATING TO GAS FIRES A simulated solid fuel effect gas fire comprising two elongate simulated solid fuel elements in the form of logs, with a partially aerated gas burner arranged in front of and below each log with respect to the front of the fire.  Thus, in use, the flames from the burners engage a lower front portion of the logs, the flames then passing around the front of the logs.  By this arrangement the lower front regions of the logs are heated to glow as radiants and the flames subsequently lick around the front of the logs as yellow flames, in accord with the visual effect of a real fire, complete combustion having been attained in the ambient atmosphere in front of the logs to thus form the yellow flames.  By the provision of nodules by virtue of a bark pattern on the upper front portion of the logs, the flames heat the nodules to red heat and enhance both the radiant heat derived from the fire and the visual effect of the fire.

Title: Flow-inducing panels for electroless copper plating of complex assemblies
Inventor: YOON SUNGHEE
IPC: C23C18/31
Filed: 1992-08-24
Abstract: Flow-inducing panels for use in electroless copper plating of complex plastic microwave assemblies. A panel comprises a rigid baffle having openings adapted to secure microwave assemblies therein. The panel has a size relative to the electroless copper plating tank that causes sufficient plating solution flow through the channels in the microwave assemblies by minimizing solution flow bypassing of the channels. This achieves complete copper plating of the inner surfaces in the channels. A relatively large panel builds up back pressure as it approaches plating tank walls, which creates a pressure differential as it moves through the plating tank, thus forcing solution through the channels. The flow-inducing panels easily hold many parts in a stabilized manner which yields high productivity, and provide solution flow through the channels using a standard metallization basket used for printed wiring board manufacturing.
