Title: Preparation of 2-hydroxy-4-methyl timobutyric acid
Inventor: RUEST DENNIS ARTHUR
IPC: A23K50/15
Filed: 1984-11-13
Granted: 1987-05-28
Abstract: A process for the preparation of 2-hydroxy-4-methylthiobutyric acid having improved color, odor and lower viscosity. 2-hydroxy-4-methylthiobutyronitrile is hydrolyzed with sulfuric acid having an initial strength of between about 50% by weight and about 70% by weight on an organic-free basis, thereby producing an intermediate aqueous hydrolysis product solution containing 2-hydroxy-4-methylthiobutyramide. The 2-hydroxy-4-methylthiobuty- ramide is hydrolyzed with sulfuric acid having a strength of between about 30% by weight and about 50% by weight on an organic-free basis to produce an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutyric acid. The hydrolyzate solution is contacted with a substantially water-immiscible organic solvent in a liquid-liquid extraction system to produce an extract comprising the solvent and 2-hydroxy-4-methylthiobutyric acid transferred from the hydrolyzate. The acid product is then recovered from the extract.

Title: Remote tire pressure monitoring system employing coded tire identification and radio frequency transmission, and enabling recalibration upon tire rotation or replacement
Inventor: ROBINSON JERRY H III
IPC: G01L17/00
Filed: 1993-03-11
Granted: 1996-11-14
Abstract: A system for indicating low tire pressure in vehicles, in which each vehicle wheel has a transmitter (100) with a unique code. A central receiver (200) in the vehicle is taught, at manufacture, to recognize the codes for the respective transmitters (100) for the vehicle, and also a common transmitter code, in the event one of the transmitters (102) needs to be replaced. During vehicle operation and maintenance, when the tires are rotated, the system can be recalibrated to relearn the locations of the transmitters. The transmitters (100) employ surface acoustic wave (SAW) devices (110). An application specific integrated circuit (ASIC) encoder (130) in each transmitter (100) is programmed at manufacture, in accordance with its unique code, to send its information at different intervals, to avoid clash between two or more transmitters (100) on the vehicle. The transmitters (100) are powered by long-life batteries.

Title: Laser-protection surgical drape
Inventor: BUTTERWORTH DAVID
IPC: A61B19/08
Filed: 1993-05-07
Granted: 1995-02-16
Abstract: A multi-layer article to protect a patient from laser radiation during surgery comprises two metallic layers (12,16) sandwiching a flame-resistant, radiation absorbing layer (14). The facing surfaces of the metallic layers (12,16), adjoining the middle layer, are reflective. The top surface of the upper metallic layer has a non-reflective, flame-resistant coating (18). The radiation-absorbing layer (14) is preferably a hydrogel. The lower metallic layer (12) is preferably thicker than the upper layer and/or is of a metal that has a higher melting temperature than that of the upper layer. The article protects the patient by harmlessly dissipating the energy in a misdirected laser beam for a period of time that will permit a healthcare worker to take corrective action. <IMAGE>

Title: Processing machinery of the transfermix type
Inventor: MEYER PAUL
IPC: B29C48/67
Filed: 1993-06-03
Granted: 1995-06-08
Abstract: Processing machinery of the Transfermix type is used for mixing components, particularly rubber and plastics. It may also be used for grinding components. Transfermix machinery has a first component (1) with an internal helical thread (5) and a second component (2) with an external helical thread (4), of opposite hand but co-axial with the first thread, and co-operating so that the threads face each other and define a passage for a medium to be processed. The cross-sectional areas of the grooves of the threads vary along their length in opposite senses between maximum and minimum values. The thread (4) of which the cross-section is being reduced has at least two starts (9, 10, 11, 12) of which a first, (9), over a part of the length, is reduced at a lesser rate than the second, 10, and over a different part of the length the first start (9) is reduced at a greater rate than the second (10). In a mixing machine, this provides longitudinal mixing of the components. <IMAGE>

Title: Factor xa based anticoagulant compositions
Inventor: ESMON CHARLES T
IPC: A61K38/48
Filed: 1990-06-06
Granted: 1992-10-29
Abstract: An anticoagulant composition containing an effective amount of factor Xa having the active serine site inactivated that functions rapidly and effectively in vivo to suppress coagulation. In a preferred embodiment, Factor Xa, a serine esterase that forms a complex with Factor Va, Ca++, and phospholipid to catalyze prothrombin activation, is first inactivated with an active site inhibitor, such as dansyl-glu- gly-arg-chloromethyl ketone, to form inactivated factor Xa. In another embodiment, Factor Xa is expressed from a gene sequence wherein the portion encoding the active serine region is modified. The inactivated protein retains the ability to bind to endogenous factor Va in vivo, and has a half-life of approximately ten hours. Administration of inactive factor Xa to the blood of a patient results in the formation of inactive factor Xa-Va complexes in vivo, thereby inhibiting coagulation.

Title: Active pulse blood constituent monitoring
Inventor: KIANI-AZARBAYJANY ESMAIEL
IPC: A61B5/00
Filed: 1996-06-04
Granted: 1999-11-18
Abstract: A blood constituent monitoring method for inducing an active pulse in the blood volume of a patient. The induction of an active pulse results in a cyclic, and periodic change in the flow of blood through a fleshy medium under test. By actively inducing a change of the blood volume, modulation of the volume of blood can be obtained to provide a greater signal to noise ratio. This allows for the detection of constituents in blood at concentration levels below those previously detectable in a non-invasive system. Radiation which passes through the fleshy medium is detected by a detector which generates a signal indicative of the intensity of the detected radiation. Signal processing is performed on the electrical signal to isolate those optical characteristics of the electrical signal due to the optical characteristics of the blood.

Date Feb. 7, 1991.The electronics industry demands that hydrogen peroxide for use therein be purified to very low levels of impurities, currently at the level of a few ppb for some impurities, or even lower. However, existing methods are either inherently unsafe because they bring concentrated hydrogen peroxide into contact with a concentrate of transition metal decomposition agents for peroxide and a purification resin which acts as a source of carbon, or are unable to attain the desired impurity level. In the instant purification process, the hydrogen peroxide solution is passed through a membrane having a very small pore size which contains an ion exchange resin that is capable of removing alkali and alkaline earth metal ions from solution. The feed solution in characterized in that it contains no more than a small proportion by weight of transition metals that catalyse hydrogen peroxide decomposition compared with the total metals content. The feed solution in some embodiments results from a prior treatment of an iron or copper contaminated solution with a dispersion of stannic oxide.
