Patent EP-0411133-A4 (EP)
Title: Combustion apparatus and its combustion control method
IPC: F23G5/46
Filed: 1989-10-19
Abstract: A combustion apparatus has a combustion furnace section, a free board section which is downstream of the combustion furnace section, and a post-combustion chamber which is downstream of the free board section, the post-combustion chamber being disposed at a position offset from the position directly above the free board section, wherein the apparatus is characterized in that a gas blowing structure is provided in the vicinity of the boundary between the free board section and the post-combustion chamber, the gas blowing structure having a plurality of pipes disposed parallel to each other at a predetermined spacing, each pipe being provided with a gas outlet hole for blowing a gas, for example, air, counter to the combustion gas flowing toward a discharge port. With this arrangement, when a gas is blown in from the gas blowing structure counter to the combustion gas, a large whirling flow, in which the combustion gas and the gas thus blown mix together, is generated in the free board section, so that unburnt gas and combustion air are thoroughly mixed together within the free board section, thus enabling complete combustion.

Title: Oilfield equipment identification apparatus
IPC: G06K19/077
Filed: 1991-05-02
Abstract: An apparatus for identifying equipment, including the maintenance of usage histories for the equipment and recommending whether the equipment is to be used in a prospective application based on prospective application and usage history. A portable encapsulated passive circuit capable of transmitting an identification code is affixed to a piece of equipment. The circuit is activated by a portable reader which receives and decodes the identification code and transmits it to a central computer. The central computer verifies the reader and the existence of the equipment in a database and retrieves the usage history for the equipment. Based on the usage history, the prospective application and guidelines for usage of equipment, the computer determines the advisability of using the equipment in the prospective application and transmits the recommendation back to the portable reader.
Patent EP-0549798-A4 (EP)
IPC: C21C5/56
Filed: 1991-09-17
Abstract: The proposed method is characterized in that the liquid bath is constituted by the melt of a low-carbon steel and molten slag. Oxidation and reducing zones are created through which, along a closed path on the surface of the molten low-carbon steel, is circulated the molten slag, into which are blown powder slag materials which are melted with the heat of a fuel-oxygen torch immersed into the melt. The said method is carried out in a melting reservoir shaped as a closed annular chamber (1) provided with partitions (11) hermetically dividing the gas space above the molten slag into oxidation (6) and reducing (7) zones. <IMAGE>
Patent EP-0566657-A4 (EP)
IPC: G01B11/06
Filed: 1992-01-10
Abstract: The ellipsometer (1) and method involve directing polarized light for interaction with an optical system (2) under study at different angles of incidence from a single beam of light and detecting the light interacted with the optical system by reflection and/or transmission for each of a plurality of different angles of incidence. The simultaneous illumination of the optical system under study at a whole range of angles of incidence  alpha  from a single beam of light and the collection a large multiplicity of data from the different angles detected can be accomplished rapidly and easily and with accuracy without scanning and with only one ellipsometer. A lens (7) is used to focus the incoming light to provide the range of different angles of incidence  alpha . The range of angles is at least one or two degrees and preferably thirty degrees or more. A second lens (8) refocuses the interacted light to a linear, multi-element detector array (6) which extends in the plane of the incidence. Each of the detector elements (9) detects a narrow range of angles of incidence within the relatively wider range of angles of incidence of the illuminating beam. If the incident illuminating rays are polychromatic and a wavelength dispersing element (10) acts on the reflected rays each detector element of a square array (11) detects a narrow range of wavelengths and angles of incidence.

Title: Polyoxypropylene/polyoxyethylene copolymers with improved biological activity.
Inventor: EMANUELE R MARTIN
IPC: A61K31/765
Filed: 1992-03-18
Abstract: The present invention comprises novel preparations of polyoxypropylene/polyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. Because the preparations of polyoxypropylene/polyoxyethylene copolymers which comprise the present invention are a less polydisperse population of molecules than the prior an polyoxypropylene/polyoxyethylene copolymers, the biological activity of the copolymers is better defined and more predictable.

Title: Novel synthetic peptide, lung surfactant containing the same, and remedy for respiratory distress syndrome
Inventor: TAKEI TSUNETOMO
IPC: C07K14/785
Filed: 1994-12-07
Abstract: A synthetic peptide containing the following sequence: Xaa-Pro-Val-Xbb-Xcc-Lys-Arg-W, (wherein Xaa is absent or represents Cys or Ser; Xbb represents His or Asn; Xcc represents Leu or Ile; and W represents a hydrophobic peptide portion); an intermediate for producing the peptide; a process for producing the peptide; a lung surfactant comprising the peptide and a lipid mixture; and a remedy for respiratory distress syndrome containing the surfactant as the active ingredient. The peptide is easy to isolate and purify and suitable for mass production. As it is highly soluble in methanol and the like, it can readily be blended with a lipid mixture and is suited for the preparation of a lung surfactant. As the lung surfactant has a good suspensibility and a potent surface activity, it is useful as a remedy for respiratory distress syndrome.

Title: File transfer method and apparatus using hash numbers
Inventor: HARLAN JIM
IPC: H04L29/08
Filed: 1994-12-27
Abstract: The present invention facilitates and speeds the transmission of a copy of a new file (13) to a receiving computer (2) where the receiving computer (2) has an old file (23). The sending computer (1) does not know the status or content of the old file (23). As a preliminary step, the receiving computer divides the old file into segments, and calculates a hash number for each segment. The receiving computer (2) then transmits these hash numbers to the sending computer (1). The sending computer (1) examines each segment in the new file (13) to determine which, if any, segments in the new file (13) have hash numbers that match the hash numbers received from the receiving computer (2). The sending computer (1) sends to the receiving computer (2) those bytes from the new file (13) that are not part of any matching segment and an indication where matching segments fit into the new file (13). Finally, the receiving computer (2) constructs a copy of the new file (13C) from the bytes received and from the matching segments in the old file (23).

Title: Fluid delivery system for hysteroscopic surgery
Inventor: GOLDRATH MILTON H
IPC: A61M3/02
Filed: 1995-04-11
Abstract: An open loop system for delivering fluid during hysteroscopic surgery. The system includes first and second fluid conduits (12, 14) in fluid communication with the uterine cavity of a patient. First and second measuring devices (26, 28) are provided for measuring the amount of fluid flowing into and out of the uterus. The measuring devices (26, 28) produce electronic signals which are communicated to a controller (30) which uses them to calculate a value reflecting the difference in in-flow and out-flow. This difference is then compared with a preset value; if the preset value is exceeded, the surgeon knows the patient is absorbing too much fluid, and the procedure may be terminated.
