Title: Dual-wavelength photometer and fiber-optic sensor probe
Inventor: PORTER MARC D
IPC: G01N21/77
Filed: 1992-09-17
Granted: 1997-07-22
Abstract: A dual wavelength optical sensor for measuring the optical characteristics of sensing films which are responsive to a particular quantity to be measured. The optical sensor includes a light source for producing light outputs at two distinct wavelengths and transmitting twin components of light to first and second outputs. A time-shared optical fiber receives the two distinct wavelengths of light from the first output and carries the light on a time-shared basis to a sensor probe. A sample detector receives the two distinct wavelengths of light transmitted from the thin sensing film. A reference detector receives the two distinct wavelengths of light from the second output and monitors the output intensity of the light source. A signal processing system combines the measurements of the optical characteristics of the thin sensing film in response to each of the two distinct wavelengths to provide measurements which account for changes in the optical properties of the thin sensing film.

Abstract: Radiant emitting walls enclose opposite sides of a central combustion chamber in an oven where coated objects to be dried are placed or passed.   The radiant emitting walls generate primarily infrared radiation and have a nonuniform temperature distribution so that the temperature of  the  lower portion  of  the  oven  can be  selectively adjusted to be significantly higher than the temperature of the upper portion.  An insulated outer housing surrounds the radiant walls and defines combustion chambers each having a linear burner which runs substantially the entire length of the radiant emitting walls.  The lower portions of the radiant emitting walls receive energy primarily from radiation from the linear burners and the upper portions of the radiant emitting walls receive energy from primarily radiation from the interior radiant emitting surfaces of the insulated outer housing and convection from the linear burners.   The  temperature  distribution of  the radiant emitting walls can be selectively varied by varying the distance between the burners  and the  radiant  emitting walls.

Title: System and method for efficient caching in a distributed file system
Inventor: CANTRELL THOMAS GEORGE
IPC: G06F12/00
Filed: 1995-02-17
Granted: 2005-04-12
Abstract: A cache manager efficiently supporting both connected and disconnected client operation. A single integrated cache is maintained for file system data, status and pathname information. File system requests are satisfied by the cache if possible and passed to a remote file system for servicing if necessary. The cache manager is independent of operating system file syntax and distributed file system protocol.      Disconnected operation is supported through an aggressive caching policy and by logging of file system modifications. Modification logs are created when the client is disconnected by logging objects that optimize the log as it is created. Cache file system objects can have multiple parents each with different naming syntax because the object name is not cached.

Title: Heated nozzle manifolds in a common plane interconnected through connector manifolds
Inventor: MAK CHUN KEUNG
IPC: B29C45/74
Filed: 1996-07-05
Granted: 2007-12-18
Abstract: Injection molding apparatus with a central heated manifold, a pair of connector manifolds, and at least four nozzle manifolds mounted to extend in a common plane in a mold. A number of heated nozzles extend from each nozzle manifold. A melt passage branches in each nozzle manifold and the nozzle manifolds are made so thermal expansion slides the branches of the melt passage into exact alignment with central melt bores through the nozzles. The central manifold and the two connector manifolds extend along a central axis and each connector manifold is between each pair of nozzle manifolds which are offset from the central axis. Connector bushings slidably connect each connector manifold rearwardly to the central manifold and sidewardly to each nozzle manifold. The connector bushings slide sufficiently to provide sufficient compensation for thermal expansion and contraction to allow either the connector manifolds or the nozzle manifolds to be centrally located relative to the cooled mold, which reduces the distances the melt passage branches must slide to be in proper alignment.

Abstract: The present invention relates to an acoustic measurement method of low measurement for the determination of fluid flow velocity (v), volumetric flo w (Q) and/or mass flow rate (M) in a measurement pipe section (1) by way of determining over an exactly determined length (~a~b) the downstream propagation time TD and upstream propagation time TU for naturally occurring and/or artificially generated acoustic wave modes (15, 16) propagating upstream and downstream in a measurement pipe (1) section in the form of pla ne wavefronts at a low frequency. The pairwise opposed transducers (11, 12; 13, 14) mounted on the measurement pipe section (1) are configured by delaying, scaling and summing of the signals into at least two direction-discriminatin g filters of which one eliminates signals related to downstream acoustic waves while the other eliminates signals related to the upstream acoustic waves in the measurement pipe section (1). The output signals of direction- discriminating filters performing filtering in the same direction are compar ed with each other by forming a symmetrical equilibrium function with respect t o their delay variable from a) the cross correlation function, b) the time integral of the squared difference, or c) the time integral of the squared sum, of the output signals, wherebyone of the listed alternative functions i s computed for acoustic waves in both downstream and upstream directions. Thes e equilibrium functions are maximally symmetrical with respect to their maxima or minima when the direction-discriminating filtering is made properly and t he correct values of the acoustic wavefront propagation times TD and TU for use in the computation of both the measurement result (v, c, Q and/or M) given b y the method and the values of the delay time variables employed in the direction-discriminating filters are determined from these, maximally symmetrical equilibrium functions with the help of a certain, predetermined algorithm.

Title: Electrospray and atmospheric pressure chemical ionization mass spectrometer and ion source
Inventor: BAJIC STEVAN
IPC: H01J49/26
Filed: 1996-12-13
Granted: 2001-11-20
Abstract: The invention comprises Atmospheric Pressure Chemical Ionization (APCI) and electrospray ionization sources for the mass spectrometric analysis of solutions, and associated methods.  The apparatus and methods are characterised in that ions generated by APCI or electrospray are directed such that their directions of travel immediately on formation can be resolved into two perpendicular components, one of which is aligned with a linear first trajectory which passes through an entrance orifice, an extraction chamber and into an evacuation port through which the extraction chamber is evacuated. The direction of travel is such that the component of velocity so aligned is smaller than the component perpendicular to it.  Ions leave the chamber along a second trajectory which is inclined at an angle between 30 and 150° to the linear first trajectory and may pass into a mass analyzer.  The invention provides improved sensitivity and a lower noise level in comparison with prior apparatus and methods using APCI and electrospray ionization sources.
