  • Patent number: 6833544
    Abstract: A method of and apparatus for analyzing a stream of ions first subjects astream of ions to a first mass analysis step, to select ions having a mass-to-charge ratio in a first desired range; this enables a mass analyzer with highresolution to be used. The selected ions are then passed into a radiofrequency linear ion trap containing a gas. The trapped ions are caused to collide with the gas, either by being injected with a high axial energy or by application of external excitation to cause fragmentation. Fragment ions of a given mass-to-charge ratio can then be isolated and excited to produce fragments of fragments. This process can be repeated to give multiple steps of mass spectrometry, MSn. The fragment ions, and undissociated precursorions are then passed out of the linear ion trap and subjected to a further mass analysis step, for example in a time of flight device, to determine the mass spectrum of the ions.

  • Patent number: 6558608
    Abstract: A method of constructing large, unitary, fiber-reinforced Polymer composite containers using a vacuum assisted resin transfer molding process. The method allows for the construction of container systems with only two separately molded parts—an open box consisting of a base (i.e., floor), 2 sidewalls and 2 endwalls, and a cover (i.e., roof). The method results in a structure which maintains the continuity of the reinforcement fibers across the junction between the floor, side, and end walls corners. This method can be applied to very large composite structures such as railcar bodies, intermodal containers, and shelters.

  • Patent number: 6534765
    Abstract: There is provided a method of, and apparatus for, analyzing a sample of an analyte provided as a sample solution comprising a solvent and an analyte. A dopant is provided, either separately or as the solvent of the sample solution. The sample solution is formed into a spray, for example in a nebulizer, and the solvent evaporated. The sample stream is irradiated in a region at atmospheric pressure, either in the liquid state prior to formation of a spray, or in the liquid state after formation of a droplet spray, or in the vapour state after evaporation of the sprayed droplets, to ionize the dopant. Then, subsequent collisions between the ionized dopant and the analyte, either directly or indirectly, result in ionization of the analyte. Analyte ions are passed from the atmospheric pressure ionization region into a mass analyzer for mass analysis. This technique has been found to give much enhanced ionization for some substances, as compared to atmospheric pressure chemical ionization.

  • Patent number: 6372019
    Abstract: An apparatus for liquefying a gas has a nozzle having a convergent nozzle portion and a nozzle throat, and a divergent nozzle portion (in the case of supersonic flow), and a working section. Vanes or another mechanism for creating a swirl velocity are connected to the nozzle, to create a strong swirl velocity in gas fed to the nozzle. In the nozzle, the gas adiabatically expands, gas velocity increases and gas temperature drops, to promote the condensation of gas with formation of droplets. The gas then passes through a working section having a wall, whereby further condensation of at least a portion of the gas flow occurs and droplets of condensed gas grow. Centrifugal effects generated by the swirl velocity drive the droplets towards the wall of the working section. Condensed liquid gas droplets are separated from remaining gas in the gaseous state at least adjacent the wall of the working section.

  • Patent number: 6211880
    Abstract: A display for presenting trends in financial commodities such as stocks. The display is made up of an array of rectangular boxes each representing an individual stock. Each display is dedicated to a different sector of the market. The color of the individual boxes is representative of the degree of fractional deviation of the most recent trading price of that stock from an assigned selected reference value, e.g., the price at the end of the previous trading session. Preferably, the location of each individual stock within the display is determined by the degree of influence that the user is to perceive that stock has upon one characteristic of the market, e.g., the volatility on one axis and perceived source of volatility on another axis, or the stocks can be located in accordance with decreasing market share on one axis and decreasing capitalization on the other.

  • Patent number: 5848546
    Abstract: A method of gripping a metal tubular member during a forming operation to resist damage to the gripped ends and reduce scrap, includes providing an outer tool having a recess structured to receive an end of the tubular member, inserting a resilient mandrel into the end of the tubular member and inserting the tubular member end into the recess. A compressive force is applied to the resilient member in a direction aligned generally axially of the tubular member to establish transverse expansion of the resilient member in order to clamp the tubular member end between the mandrel and the outer tool recess. The tube may be stretched beyond the yield point and formed while so clamped, after which the compressive force is removed so as to facilitate withdrawal of the formed tube. In one embodiment, the mandrel may consist of a composite which may have a lower durometer hardness inner portion and higher durometer hardness outer portions.

  • Patent number: 4718450
    Abstract: A valve head of the pressure relief valve is urged into the closed (seated) position by a spring, assisted by a force derived from pressurized fluid which is situated in a chamber behind the valve head and which is admitted thereto from the upstream side of the valve seat through a chamber in the valve head. The chamber in the valve head is open toward the inlet port of the valve and is partly defined and surrounded by a skirt-like extension oriented transversely to the axis of the valve inlet port. The diameter of the chamber whose opening has a plane generally perpendicular to the direction of valve head motion, is at least as large as the diameter of the valve intake port. In the seated (closed) state the skirt-like extension reaches transversely into the inlet port at least as far as the axis of the inlet port and in the maximum open position the skirt-like extension is at the most just clear of the inlet port.
