Title: Figure eight linear dispenser
Inventor: CHESLER RONALD B
IPC: G02B6/44
Filed: 1992-04-15
Abstract: FIGURE EIGHT LINEAR DISPENSER               ABSTRACT A figure eight linear dispenser (10) having an optical fiber winding configura-tion adapted to dispense an optical fiber waveguide (14) at high speed. The dispenser (10) is built up of a series of flat winding layers, with each layer comprising an inter-laced figure eight pattern. More particularly, the dispenser (10) comprises a housing having a pair of bobbins (12a, 12b) respectively centered on a pair of half-circular outer guides (13a, 13b). The optical fiber waveguide (14) is wound around the bobbins (12a, 12b) inside the outer guides (13a, 13b) in a series of layers (15a-15e) of figure eight loops (16a-16e). An optional cover may be disposed over the bobbins (12a, 12b) and the guides (13a, 13b) in order to enclose the waveguide (14). The waveguide pay-out of the dispenser (10) through a properly spaced eyelet (17) is nearly helix-free and linear as a result of cancellation of the angular momentum in the paired figure eight loops (16a-16e). The dispenser (10) permits linear (helix-free) payout at higher speeds than other types of linear dispensers. This is accomplished by a reduction in the wave-guide tension for a given payout velocity. The dispenser (10) increases the applicabili-ty of fiber tethered links to a wider range of high performance missiles and vehicles be-cause of its increased payout speed and linear payout capability. Linear payout allows ducting of the paid out fiber to avoid a direct thrust missile plume. The dispenser also uses a relative small exit aperture or eyelet (17) for the fiber waveguide (14) which reduces aerodynamic drag and radar cross section of the carrying vehicle.

Also included is a delay for delaying the energizing current flow between the power supply and the humidification device for a given period after the level of liquid in the reservoir reaches the minimum liquid level. The provision of a delay prevents the premature flow of current to the humidification device.

Title: Homogeneous-heterogeneous catalyst system for polyolefins
Inventor: SHAMSHOUM EDWAR SHOUKRI
IPC: C08F4/642
Filed: 1992-09-08
Abstract: This invention concerns a catalyst system comprising at least one homogeneous catalyst and at least one heterogeneous catalyst, specifically, a metallocene catalyst and a conventional Ziegler-Natta catalyst, respectively. This invention is useful in the polymerization of any polymer in which separate polymerizations with a homogeneous catalyst and with a heterogeneous catalyst are possible, but preferably, polymerization of olefins, more preferably, a-olefins, and, most preferably, propylene. This invention provides a catalyst system which facilitates use of a homogeneous catalyst but eliminates the disadvantages of such a system. This invention produces a polymer with molecular weight distribution (MWD) as broad or broader than the MWD of the heterogeneous catalyst alone. Hydrogen can be used to control molecular weight distribution of a polymer produced with this invention.

Title: Stable polyamide resin dispersions and methods for the manufacture thereof
Inventor: SMITH GEORGE A
IPC: C09D177/00
Filed: 1992-01-03
Abstract: Stable aqueous dispersions of polyamide resin in water comprise a surfactant and at least one amino acid of formula (I), or an anionic or cationic salt thereof, wherein "R" represents an alkylene, alkenylene or arylene group of one to ten carbon atoms and "Y" is hydrogen or a polar or non-polar ionic or non-ionic substituent, in an amount effective to improve the stability of said aqueous dispersion.      Polyamide resins have properties that render them useful in a variety of applications, including coatings, adhesives and printing inks. Owing particularly to the high melting points and the insolubility of polyamide resins, however there have been difficulties in the prior art in using polyamide resins in these applications. The stable aqueous dispersions of the present invention facilitate these uses of polyamide resins.

Filed: 1991-10-08
Abstract: An on-line multidimensional chromatographic system (10) and method which couples a liquid chromatograph (12) to a supercritical fluid chromatograph (58). The system (10) includes an inlet column (36) for depositing a fraction of interest eluting from the liquid chromatograph (12), an interface (54) interposed between the inlet column and the supercritical fluid chromatograph (58) for receiving and trapping an analyte from the deposited fraction on an impacted surface (74), and a valve arrangement (18, 20, 22, 24) for controlling fluid flow throughout the system (10). After the fraction of interest has been deposited in the inlet column (36), the liquid chromatograph solvent is removed from the inlet column (36), and then the deposited fraction is extracted from the inlet column (36) in a supercritical fluid stream. The supercritical fluid stream is directed into the interface (54), where the analyte is trapped while the supercritical fluid is decompressed and vented. A subsequent supercritical fluid stream is then used to introduce the trapped analyte directly into the analytical column (56) of the supercritical fluid chromatograph (58).

Title: Metropolitan area distributed switching telecommunications network
Inventor: DU FEU DAVID K
IPC: H04W84/16
Filed: 1993-06-16
Abstract: Abstract The Metropolitan Area Distributed Switching Telecommunications Network (MADN) is a radio-based telecommunications overlay network that features: fully digital switching systems, modified for strategic placement in high traffic density urban area office and/or apartment buildings; integrated wireline and wireless subscriber access networks and short-haul digital radio transport facilities. The unique arrangement of switches, individually placed in each building, feature large capacity, powerfill 32-bit microprocessors providing increased call processing and network architecture capacity and flexibility. This distributed environment facilitates adjustments to the processing capacity in proportion to the growing demand, makes for a more efficient network architecture, and enables call processing functions to be performed at the point of application rather than in traditional central offices. This overlay network will work completely independent of the regular Public Switched Telecommunications Network (PSTN), operated by the local telecommunications operator and will offer all subscribers connected to the network a vast range of voice features and services, not always available in the regular traditional network. These networks will be packaged as a unit, easily and quickly deployed in any urban business and residential environment providing switched voice and wideband data services.
