Title: Instrument for determining the optical density of fluids
IPC: G01N21/85
Filed: 1970-06-26
Abstract: 1331496 Monitoring fluids photo-electrically V S GRIFFITHS and R HOWES 10 June 1971 [26 June 1970] 31006/70 Heading G1A In an instrument for determining the optical density of a fluid, light from a source 1 is received by a photo-cell 5 after passing through the fluid contained in a cavity 12. A filter 2 monochromator, and a reflecting prism 6, may also be provided in the probe, and the detector may be a photodiode, a photovoltaic or photo-emissive cell, a photo-transistor, thermopile, thermistor, photo-pneumatic or Golay cell. The probe is inserted into the fluid to be measured, e. g. a liquid sample or flowing exhaust gases, and the photo-cell output is displayed on a meter, which has previously been calibrated or a recorder.

Title: Gas filled thyratron type switching discharge tubes
IPC: H01J17/56
Filed: 1973-02-13
Abstract: 1334527 Gas filled thermionic valves ENGLISH ELECTRIC VALVE CO Ltd 13 Feb 1973 46213/70 Heading H1D A gas filled thyratron comprises a cathode, an anode and a control grid; the anode including two electrodes between which a plasma is generated. The anode arrangement prevents damage by positive ion bombardment when the current through the thyratron is reversed. The thyratron is symmetrical about a plane I-I. Each half comprises an anode/cathode 18 including a thermionic cathode 22 with a heater 24 and heat shield 26 and a discharge electrode 28. A control grid 32 comprises a cylindrical section 34, a pair of apertured plates 36, 38 and a member 40 partially filling the apertures. Electrodes 90, 84 of similar construction and with cooling members 42 are maintained at intermediate potential to prevent voltage breakdown. The envelope consists of sections 10, 10a, 10b and is filled with hydrogen, deuterium and tritium. A H 2  reservoir 50 is mounted adjacent the electrode structure and is heated to maintain the gas pressure. A plasma discharge between cathode 22 and electrode 28 is produced by applying a positive potential to electrode 28. The thyratron acts as a switch in an oscillator circuit. A negative potential applied to grid 32 via a transformer 63 prevents firing until a pulse is applied to the transformer. This renders the grid positive, electrons are attracted from the plasma and the gas filling becomes ionized. Positive ions are absorbed in the plasma of the cathode.

Title: Compositions comprising haloperoxidase for inhibiting the growth of pathogenic microbes and a method for inhibiting growth of pathogenic microbes using said compositions
IPC: A01N63/50
Filed: 1992-02-18
Abstract: Haloperoxidases are used to selectively bind to and, in the presence of peroxide and halide, inhibit the growth of target microbes without eliminating desirable microbes or significantly damaging other components, such as host cells, in the environment of the target microbe. When a target microbe, e.g., a pathogenic microbe, has a binding capacity for haloperoxidase greater than that of a desired microbe, e.g., members of the normal flora, the target microbe selectively binds the haloperoxidase with little or no binding of the haloperoxidase by the desired microbe. In the presence of peroxide and halide, the target bound haloperoxidase catalyzes halide oxidation and facilitates the disproportionation of peroxide to singlet molecular oxygen at the surface of the target microbe. The lifetime of singlet molecular oxygen restricts damage to the surface resulting in selective killing of the target microbe with a minimum of collateral damage to the desired microbe or physiological medium. The methods and compositions of the invention are highly useful in the therapeutic or prophylactic antiseptic treatment of human or animal subjects, since their use can be designed to be highly effective in combatting bacterial or fungal infections without significant damage to normal flora or host cells. Suitable haloperoxidases include myeloperoxidase (MPO), eosinophil peroxidase (EPO), lactoperoxidase (LPO), chloroperoxidase (CPO) and derivatives thereof capable of selective binding to target microbes.

Title: Plasma torch for use in a waste processing chamber
Inventor: GNEDENKO VALERI G
Filed: 2005-04-28
Abstract: The invention is a plasma torch for insertion through an opening in the wall of a waste processing chamber. The plasma torch of the invention is characterized by comprising a coaxial sleeve having an upper end and a lower end. The sleeve surrounds at least the portion of the outer surface of the torch that is located in the opening, thereby forming an insulating chamber between the outer surface if the torch and the inner surface of the sleeve. At least a portion of the portion of the coaxial sleeve that surrounds at least the portion of the outer surface of the torch that is located in the opening in the wall of the processing chamber is porous or permeable to a heat exchanging fluid. The torch comprises an inlet for introducing the heat exchanging fluid into the insulating chamber. When the plasma torch is inserted through the opening, a gap exists between the processing chamber wall and the coaxial sleeve. Thus the coaxial sleeve and the insulating chamber shield the outer surface of the plasma torch from a significant amount of the heat that radiates from the processing chamber wall and from inside the processing chamber and the heat exchanging fluid that flows through the inlet exits the insulating chamber into the processing chamber.
