Abstract: The secure electronic distribution of research documents over the world wide web to investors. A repository server (2) receives research documents from contributors (14, 16, 18, 20, 22). Also received are corresponding document profiles with information relating to each research document including authorization information specifying who is permitted to access each research document. The repository server (2) includes a first database (11) for structured query searches and a second database (13) for full text searches.  The web server (4) receives requests from investors for research documents that satisfy a query. The web server (4) determines whether the first database (11) or the second database (13) should be searched based upon the type of query. The repository server (2) transmits to the web server (4) a list of research documents that satisfy the query and which the investor is authorized to access according to the authorization information. The web server (4) formats the list of documents according to a template form. Optionally, queries can be optimized.

Abstract: A stent is placed in a tubular structure of the anatomy such as the vascular or respiratory system by advancing a probe bearing the stent into the body. The disposition of the probe, and hence the disposition of the stent are monitored using a system which transmits non-ionizing fields between a transducer or transducers on the probe and external transducers. The disposition of the stent relative to the tubular structure is depicted showing a representation of the stent superposed on an image of the tubular structure.  This provides accurate placement, particularly for complex stents with features such as one or more branches which must be aligned with anatomical features.

Abstract: An ISDN or other enhanced bulk delivery telephone signal is processed by a channel bank receiver to preferrably produce a plain old telephone signal output having dialed number and caller I.D. as lead information. This signal is advantageously used by a security station receiver to distinguish different calling alarm panels which may not be uniquely identified by their own address. This information also allows more effective processing of telephone signals received by the security station.

Abstract: A PLL-based frequency synthesizer is provided that includes a phase detector, a loop filter, a VCO, a sampler and filter system, and a frequency divider. This architecture reduces the high division ratio (N) necessary in a classical PLL-based frequency synthesizer while maintaining low phase-noise. This is achieved through sub-sampling the VCO output signal in the feedback path. The sampler is placed in the feedback loop following the VCO  and is clocked at a low frequency (sub-sampling). The output of the sampler is the beat frequency between the VCO frequency and the sampling clock (in addition to harmonics that are filtered-out by a low-pass filter (LPF)). The LPF in the feedback loop attenuates any tones resulting from the sampling operation. A frequency divider is then used to bring down the feedback signal to the frequency of the phase detector input. Since the feedback signal has already been reduced in frequency by the sampling operation, the division ratio (N) in this frequency divider is greatly reduced when compared to the classical PLL-based frequency synthesizer. The reduction of the division ratio is beneficial because it reduces the output phase-noise due to the phase detector and the reference signal. Also, if a DDS is used to drive the PLL, the reduced division ratio will also reduce the number of bits needed for the DDS, thus reducing its power consumption.

Abstract: A gas turbine engine blade tip clearance control system and method is described. An annular housing is formed about an engine casing to which an annular shroud segment assembly is secured and closely spaced about blade tips of a stage of blades. The annular housing forms an air passage means communicating with the casing for directing a cooling air stream to the casing. A thermally operable passive ring valve is formed by two overlapped metal ring segments having a dissimilar coefficient of thermal expansion selected whereby to produce a radial gap between the ring segments when the valve temperature reaches a predetermined value. The radial gap admits a cooling air flow into the housing for cooling the casing and its associated shroud segment assembly to control radial growth and thereby prevent blade tip pinching.

Abstract: In a method of converting slags derived from nonferrous metallurgy, in particular primary and secondary Ni and Cu metallurgical slags, while recovering and/or enriching the nonferrous metals and forming synthetic puzzolans, the molten oxidic slags are reduced with gases containing H2 and CO such as, e.g., cracked gas in a first reduction stage above a metal bath containing Cu and/or Ni and optionally Co. The redox potential of the CO/H2 mixture is reduced by adding 10 to 40% by volume H2O vapor and/or CO2 in order to hold off the reduction of Fe oxides. Subsequently, the remaining slag free of Cu and Ni is further reduced above an iron bath while using carbon in order to reduce the portion of Fe oxides so as to produce a slag free of Fe and nonferrous heavy metals.

Title: Apparatus for chopping and discharging straw from a combine harvester
Inventor: REDEKOP LEO
IPC: A01F12/40
Filed: 2001-03-06
Granted: 2004-12-21
Abstract: A chopper and discharge apparatus includes a stationary housing for attachment to the rear discharge of a combine harvester so that straw is fed from the combine into an inlet of the housing and is discharged from an outlet of the housing. Within the housing is mounted a hub for rotation about the horizontal axis with the hub carrying a plurality of lugs at angularly and axially spaced positions therearound, each lug carrying a pair of pivotal blade members which are rotated with the hub in the form of flails. Each lug is associated with a stationary blade on the inside of the housing so that the pair of blades carried on each lug sweep past the stationary blade each on a respective side of the stationary blade. The blade members include some flat cutting blades and some twisted blade members which have a planar base portion attached to the lug, an outer planar blade portion and an intermediate twisted portion twisted about a center line so that the blade portion lies at an angle to the base portion. Where the angle is less than 90 degrees, the blade portion defines a leading edge and a trailing edge lying in two different axially spaced planes and the blade portion tends to generate air flow in an axial direction. Two such blades arranged with opposite angles can be carried on the same lug. Where the blades are arranged adjacent an end of the hub, the blades can be arranged with the angle tending to direct the air toward the same end thus assisting in moving the chopped material outwardly to one side of the combine.

Abstract: A MIG welding gun has a diffuser with an external thread and a frusto-conical back ramp. A nozzle assembly includes an insert with a back ramp and a thread that mates with the diffuser thread. The threads of the diffuser and insert have respective ramps that mate. A single turn of the nozzle assembly on the diffuser causes simultaneous engagement of the insert and diffuser back ramps and of the insert and diffuser thread ramps.      Such engagement centers the nozzle to be concentric with the diffuser and also produces a wedging action that retains the nozzle assembly on the diffuser until a relatively substantial reverse torque ie applied to the nozzle assembly. The nozzle front end has a narrow annulus, which reduces the amount of radiant heat from the welding are that reaches the nozzle.
