摘要： An analytical instrument, such as a mass spectrometer, the instrument having a magnetic section with a controllable electromagnetic field. Controlling the electromagnetic field is accomplished by controlling a temperature of a base plate within the magnetic section, by controlling a current passing through an electromagnetic coil disposed within the magnetic, by disposing a magnetic shunt across a portion of a yoke of the magnet, or by any of the above either independently or in combination. The magnetic shunt is configured to have a temperature coefficient of remnant flux density that is opposite the temperature coefficient of remnant flux density of a first pair of permanent magnets located within the magnetic section.

摘要： This invention relates to methods and reactor devices for controlling the oxidation of hydrocarbons to dibasic acids in the presence of a catalyst and a monobasic acid, by removing the catalyst from the reaction mixture, outside the oxidation zone, after the oxidation has taken place at least partially. Initially, the catalyst is partially precipitated and removed by reducing the water level in the reaction mixture and/or subjecting the reaction mixture to a temperature at which or over which catalyst precipitates. After the initial partial precipitation of the catalyst, the mother liquor remaining is subjected to a thermal treatment during which at least the major part of the monobasic acid is removed leaving behind molten dibasic acids, in which the remaining catalyst precipitates substantially in its totality, and it is removed. The precipitated catalyst in the two precipitation stages may be recycled in miscellaneous ways.

摘要： A mass spectrometer suitable to measure both positive and negative particles, such as ions for example in a vacuum chamber. This spectrometer is provided with a turnable permanent magnet segment, which provides the gap of a yoke with adequate magnetic flux having the appropriate direction to separate the positive or the negative particles. Changing the polarity adjusts the flight path of the ions. Thus, negatively charged ions and positively charged ions will follow similar flight paths under opposite polarities, permitting the use of a single array of detectors. One or more coils may be used in place of or in addition to the turnable permanent magnet segment in order to provide the appropriate magnetic flux to the gap, and/or facilitate the turning process of the turnable magnet segment. The turnable magnet and/or the coils may be inside or outside the vacuum chamber. The detector may comprise at least one detector area, two charge mode amplifiers coupled to the detector area, a first CCD shift register coupled to a first one of the charge mode amplifiers and a second CCD shift register coupled to a second one of the charge mode amplifiers.

摘要： Methods and devices for controlling the oxidation rate of a hydrocarbon to an acid by adjusting addition of a rate-modulator are disclosed. In order to control oxidation rate, the ratio of hydrocarbon to rate-modulator is appropriately adjusted. Preferably, this ratio is adjusted continually based on feedback relative to oxidation progress parameters. It may be kept substantially constant at steady state conditions of the oxidation, or it may take a path of predetermined values. The rate-modulator preferably comprises a hydrocarbon oxidation initiator.

摘要： A vibration-resistant two-member expansion fastening device characterized by quick lock and release. The first (10 or 2610) of the two members has an engagement edge (24 or 2632) which is adaptable to apply pressure on the second member (60 or 2660) at a low energy position (76 or 2676). The second member (60 or 2660) has either a recessed surface (70) or a threadline with threads (2684), the diameter of which decreases in a direction from a front point (74) or leading point (2666) away from the second head (64 or 2664) towards a back point (76 or 2676) close to the second head (64 or 2664), thus forming the low energy position. This configuration provides the fastening device with highly desirable characteristics, such as easy insertion of the second member (60 or 2660) into the first member (10 or 2610) by a simple pushing-in action, extraction of the first member by standard unscrewing, optionally followed by pulling, and vibration-proof properties.

摘要： A focal plane detector assembly of a mass spectrometer includes an ion detector configured to detect ions crossing a focal plane of the spectrometer and an electrically conductive mesh lying in a plane parallel to the focal plane, positioned such that ions exiting a magnet of the mass spectrometer pass through the mesh before contacting the ion detector. The mesh is maintained at a low voltage potential, relative to a circuit ground, which shields ions passing through the magnet from high voltage charges from other devices, such as microchannel plate electron multipliers. The mesh may be mounted directly to the magnet or positioned some distance away. The detector array may include any suitable device, including a faraday cup detector array, a strip charge detector array, or a CCD detector array.
