Title: Seam plate for retaining roof decking membrane
Inventor: HASAN S RIAZ
IPC: E04D5/14
Filed: 2002-07-17
Granted: 2006-06-06
Abstract: A stress plate or seam plate for use in connection with securing membrane sheets to underlying roofing decking substructure comprises a circular disk having a central aperture for receiving a screw fastener. A plurality of concentric ribs are defined between the central aperture and the peripheral edge of the plate for providing reinforcing and bending or flexibility characteristics to the stress plate or seam plate, and in accordance with the principles and teachings of the present invention, a plurality of circumferentially spaced, downwardly extending projections having substantially V-shaped cross-sectional configurations are provided upon the underside of the seam or stress plate so as to engage the membrane sheets and retain the same at their desired locations upon the underlying roofing deck substructural assembly. Contrary to conventional stress plates having sharp-pointed prongs or tangs, the projections of the present invention have substantially rounded or radiused apices so as not to puncture or rupture the membrane sheets.

Granted: 2006-03-21
Abstract: The present invention relates to a frequency divider with an adjustable divider ratio (TV). Such circuits are subject to demands for ever higher clock frequencies. The present invention achieves this object by virtue of the fact that the circuit generates the output signal (OUT) in a blockwise manner and converts it into a sequential signal in a parallel-serial converter (MUX) on the output side and outputs it in a bitwise manner. As a result, the essential part of the frequency divider circuit can be operated with a slower frequency (C4) than the input frequency (C), which in turn enables higher input frequencies (C).

Abstract: In a domestic gas water heater, it is necessary to exhaust the product of combustion through a flue. In this invention, combustion products generated by a burner pass through a flue, generally circular in cross section, is helically and coaxially composed of within the tank. This then comprises an upward spiral path for the combustible gases to be discharged. Properties of this embodiment cause the flue to provide excellent heat exchange with the water therein and to be heated through the large surface area exposed to the water. The gravitational flow of the exhausting hot flue gases causes high efficiency and markedly diminishes the overall gas consumption. In order to prevent heat loss in the standby mode, a damper provided in the flue on top of the water containing tank will be closed. This will maintain the heat retention within the flue and to cause the heat therein to further dissipate within the water to be heated.

Title: Examining a diamond
Inventor: LAWSON SIMON CRAIG
IPC: G01N21/87
Filed: 2002-09-12
Granted: 2010-06-29
Abstract: In order to determine whether a blue-to-green diamond (1) has been artificially irradiated or ion bombarded to change its colour, it is irradiated with light of 633 nm wavelength in order to stimulate the emission of luminescence, and luminescence from about 680 to about 800 nm is detected using a confocal microscope (3) and a spectrometer (8) as the focal plane (9) is scanned vertically through the diamond (1). A rapid decrease in luminescence with increase in depth indicates natural irradiation whilst a more rapid decrease indicates ion bombardment. Alternatively, in order to determine whether a diamond (1) is a natural/synthetic doublet, it is irradiated with radiation of 325 nm wavelength in order to stimulate the emission of luminescence, and luminescence from 330 to 450 nm is detected. An abrupt change in luminescence with increase in depth indicates that the diamond is a natural/synthetic doublet.

IPC: E21B47/09
Filed: 2004-04-07
Granted: 2009-06-09
Abstract: Methods and systems for optical endpoint detection of a sliding sleeve valve are disclosed. The system comprises fiber optic cable based sensors (e.g., fiber Bragg gratings or fiber optic coils) positioned in a recess within the valve's housing and affixed proximate to the ends of the cavity in which the sleeve travels. When the sleeve reaches the ends of the cavity, it imparts a stress onto an area of the housing, which preferably constitutes a protrusion within the cavity, which in turn stresses the sensor and changes its reflection profile. This change in reflection profile indicates that the sleeve has traveled to an end point inside the valve, and accordingly that the valve is fully open or fully closed.

Title: Method and system for multi-level power management of an optical network including automatic initialization
Inventor: BIERMAN ROBERT MICHAEL
IPC: H04B10/294
Filed: 2003-01-10
Granted: 2009-06-02
Abstract: A method and system for multi-level power management in an optical network is provided that may also perform automatic initialization of the network. The power management provides three levels of control of an amplifier in the optical network. The first level of control maintains the gain of the amplifier operating in automatic gain control (AGC) mode at a target amplifier gain. The second level of control eliminates channel gain excursion by dynamically changing the amplifier target gain so as to provide that the gain for each channel is within a gain ripple of the amplifier. The third level of control sets the target gains of amplifiers according to fiber span losses.  The third level of control may also perform pre-emphasis of channel powers by changing the power of one or more channels passing through the amplifier so as to compensate for gain ripple of the amplifier. As a result, this multi-level control of the amplifiers in the network provides an increased level of optical signal to noise ratio (OSNR), protection of network components, and stabilization of channel power in the network.
