Title: Erbium doped optical devices
Inventor: FELDMAN LEONARD CECIL
IPC: H01S3/05
Filed: 1993-05-13
Granted: 1998-07-14
Abstract: This invention embodies an optical device with a Fabry-Perot cavity formed by two reflective mirrors and an active layer which is doped with a rare earth element selected from lanthanide series elements with number 57 through 71. The thickness of the active layer being a whole number multiple of .lambda./2 wherein .lambda. is the operating, or emissive, wavelength of the device, said whole number being one ofthe numbers ranging from 1 to 5, the fundamental mode of the cavity being in resonance with the emission wavelength of said selected rare earth element, Cavity-quality factors exceeding Q = 300 and finesses of 73 are achieved with structures consisting of two Si/SiO2 distributed Bragg reflector (DBR) mirrors and an Er-implanted (.lambda./2) SiO2 active region. The bottom DBR mirror consists of four pairs and the upper DBR mirror consists of two-and-a half pairs of quarterwave (.lambda./4) layers of Si and SiO2. Photoluminescence at room temperature reveals a drastic enhancement of the luminescence intensity of the cavity emitted along the optical axis of the cavity versus the luminescence without the top mirror. The luminescence intensity of the cavity is typically 1-2 orders of magnitudes higher as compared to structures without a cavity. Furthermore, since the emission wavelength and the intensity decrease for off-normal emission angles, the change in emission wavelength can be quantitatively described by assuming that the on-axis component of the optical wave is resonant with the cavity.

Abstract: A fence system including a frame and a plurality of foraminous panels attached to the frame. The foraminous panels are constructed with continuous integral strands which are connected by integral bonds extending between each of the strands. The integral strands form a zig-zag pattern defining cell apertures therebetween. The cell apertures define a non-circular interior surface. A fastener of the fence system has a shank and a head attached to one end of the shank. A shoulder positioned between the shank and the head is shaped to cooperatively engage a cell aperture for preventing rotation of the fastener when engaged with a foraminous panel. The foraminous panels are attached to the frame with a portion of each neighboring panel having an overlapping area through which fasteners are inserted and attached. An angled top edge cap is attached along a top end of the foraminous panels and is angled to deter climbing. The top cap material is formed of foraminous panels having cell apertures generally smaller than lower panels. The top cap panel material is self-supporting but is incapable of supporting the weight of a climber.      Additionally, barbed segments are formed along a terminal edge of the top cap by shearing one of the integral strands to provide extremely sharp pointed tips.

The system includes a thermostat (10) associated with each zone of a building, and a central control unit (12) which communicates with each thermostat (10) to send temperature setpoint values to each thermostat (10) for the purpose of conserving energy and reducing energy consumption during certain times of the day.  Each thermostat (10) is associated with either a heating or cooling device (14), where setup temperature values are sent from the central control unit (12) to the thermostats (10) where cooling devices are used in place of heating devices.  The thermostats (10) are designed to operate as stand-alone units which control the temperature within a zone based upon a temperature setpoint stored at the unit.  The temperature setpoint values are replaced by the higher or lower temperature setpoint values transmitted to the thermostats by the control units during setback or setup time periods.  To avoid the requirement of installing communication wires between the central control unit (12) and thermostat (10), each thermostat (10) and the central control unit (12) includes communications circuitry (30, 46) which allows the thermostats (10) and control unit (12) to communicate over the power conductors (36, 38) within the building.

Abstract: A synchronization adder circuit for digital data communication is provided. This circuit includes an A/D converter, a waveform-shaping circuit, a square circuit, a low-pass filter, and an adder. The A/D converter samples at given sampling points in time per sampling cycle a received signal transmitted through a plurality of subcarriers to digitize sampled values to provide digital signals. The waveform-shaping circuit then waveform-shapes the digital signals from said A/D converter without decomposing them with respect to each subcarrier. The square circuit squares the output signals from the waveform-shaping circuit. The low-pass filter removes a given high-frequency component from output signals from the square circuit. The adder adds values of output signals from the low-pass filter at each sampling point for preselected sampling cycles to determine the samples suitable for reproduction of original data.

Title: Process and plant for decontaminating solid materials contaminated with organic pollutants
Inventor: WEBB LESLIE
IPC: C12S9/00
Filed: 1993-08-23
Granted: 2004-03-16
Abstract: In order to decontaminate solid materials contaminated with organic pollutants, in particular soil contaminated with poly-cyclic aromatic hydrocarbons, the materials are mixed with a micro-emulsion, if required after being crushed and mechanically disaggregated. The organic impurities are solubilized in the apolar compartment of the micro-emulsion and the micro-emulsion is decomposed, in particular by temperature change, into a tenside-rich phase and into a pollutant-containing phase. By using mic-ro-emulsions of biodegradable components, the purified solid materials, in particular purified soil, may be returned to the envir-onment. A plant for carrying out the process has a multiple-stage extraction device (3), in which the contaminated solid material is mixed with the micro-emulsion and the impurities concentrate in the apolar oil phase. In a separating device (6), the extracted solid material is separated from the contaminated micro-emulsion, which is then decomposed in a phase separating device (8) in-to a tenside-rich water phase, collected in the container (11), and into a pollutant-containing oil phase (oil container 12). By using biodegradable components for the micro-emulsion. the pollutant-containing oil phase can be reacted in a micro-organism reactor (14) in order to achieve its total degradation.

Title: Vessel mooring system
Inventor: KORSGAARD JENS
IPC: B63B21/00
Filed: 1993-12-29
Granted: 2006-07-18
Abstract: A vessel (11) with a mooring recess (15) on the bottom of the hull moors to a submerged buoyant mooring element (12) anchored to the ocean bottom by hoisting the mooring element (12) from a stowed position at a depth of net neutral buoyancy of the mooring element and its anchoring system (18) into contact with the mooring recess (15). The mooring operation is completed safely, quickly, and positively by rapidly withdrawing seawater into the hull (16) through an opening (58) in the mooring recess so as to reduce the hydrostatic pressure acting on the top of the mooring element as the element comes into contact with the hull of the vessel. The pressure reduction is sufficient to shift the mooring element and its anchoring system from a net negative to a net positive buoyancy condition at the keel depth of the vessel. The seawater may be withdrawn by a high capacity pump (56) that is either specifically installed for this purpose or is part of a bow thruster system of a type commonly found on large vessels.
