Title: Pivoting Valve Assembly
Inventor: ROBERTSON WALTER D III
IPC: F16K31/10
Filed: 1996-05-21
Abstract: An adjustable pivot valve assembly (10) for use in a fluid flow system (S). A valve body (12) has a fluid flow path therethrough and includes an inlet (14), an outlet (16), and a valve orifice (18) formed intermediate the inlet and outlet.  A valve seat (28) is mounted for movement relative to the orifice to open and close the fluid path.  The valve seat is attached to a valve stem (30). A solenoid assembly (50) is supplied with an input from a sensor/control unit (S) to effect movement of the valve seat. What would otherwise be a linear movement of the valve stem and valve seat is translated into movement of a plunger (78) interconnected with the valve stem to produce a movement which is orthogonal to a longitudinal axis of the valve stem. This translated  movement causes the valve seat to pivotally move about the orifice to effect an opening of the orifice for fluid to flow between the inlet and outlet.  The valve stem, plunger, and a pole piece (56) of the solenoid comprise a lever arm the length of which is adjustable to vary the force required to effect the pivoting movement.  A spring arrangement (86a, 86b) centers the valve stem and seat, and a spring (46) biases the valve seat toward a position closing the orifice.  Stops (90a, 90b) located on opposite sides of the plunger, at the end of the arm remote from the valve seat, limit the orthogonal movement of the valve stem.

IPC: F23D3/02
Filed: 1996-07-16
Abstract: Disclosed is a device for use in an oil lamp to allow the diffusion of the scent of a perfume added to the oil. The oil lamp has an inside and a lip lying in a generally horizontal plane. The device is a ring-shaped element having a plurality of inwardly downwardly protruding tabs that are spaced apart to define gaps therebetween permitting uninterrupted air flow between the inside of the bottle and the ambient air. The tabs have free ends defining an opening and are sized and shaped to receive and hold a wick supporting tube having a longitudinal axis perpendicular to the horizontal plane and an upper end from which a wick projects. The tube is inserted into theopening so that the upper end of the wick supporting tube is held in place at a given longitudinal distance from the lip. Thus, when the device is placed on the lip and the wick is lit, heat generated by the lighting of the wick heats the tube and the oil and causes the perfume to be released into the ambient air through the gaps to provide a pleasing smell.

Title: Method and apparatus for breaking hydrocarbon emulsions
Inventor: DAVIS ROBERT MICHAEL
IPC: B01D17/02
Filed: 1995-06-14
Abstract: A method for breaking an emulsion comprising oil and water into oil and water phases comprising treating the emulsion with a chemical demulsifier and passing the mixture through a hollow chamber (22) having a uniform cross section and subjecting the mixture to acoustic energy in the frequency range of about 1.0 to 10.0 kHz, preferably 1.25 kHz, to enhance breaking the emulsion into a water phase and oil phase. The oil phase is then separated from the water phase by gravity separation and recovered. The sonic energy is generated by a transducer (64) attached to the mid-section of the upper or lower outer surface of the hollow chamber (22). For emulsions containing light oils having an ALI gravity greater than 20 and water, the emulsion can be broken by the use for acoustic energy in the frequency range of about 1.0 to 10.0 kHz without the addition of chemical demulsifiers.

Patent CA-2185691-A1 (CA)
Inventor: LEONARD LEON R
IPC: C04B7/36
Filed: 1995-03-16
Abstract: The present invention relates to methods and systems for reducing pollutant emissions associated with combustion operations, e.g. cement manufacturing.  The invention further relates to the disposal of sludge, e.g., produced by waste water treatment plants, by introducing it into the combustion process.  In particular, the invention provides for introducing particles of aqueous sludge into a kiln at a point in the kiln effective to reduce pollutant emissions in outlet flue gasses produced by the kiln. Optimally, the sludge is introduced at a point in which maximum NOx emission rductions can occur and maximum HC1 emission reductions can occur downstream (at lower temperatures).  In a specific embodiment, introduction of about 10 to about 20 tons per hour of wet sludge results in about a 15 % to 30 % reduction in NOx emissions in a cement kiln.

Title: Cell-based clock recovery device
Inventor: COX NEIL
IPC: H04L12/70
Filed: 1995-05-30
Abstract: A clock recovery unit provides a clock recovery function in the receiving entity of a system to implement adaptation of constant bit-rate (CBR) services over an asynchronous transfer mode (ATM) or ATM-like network. Incoming cells are periodically sampled for buffer fill level Li. The maximum fill level of undelayed cells Lxj is extracted from successive series of a predetermined whole number M of buffer-fill samples Li. A frequency adjustment logic unit provides at its output a bit stream at a given clock frequency fj. The frequency adjustment logic unit makes incremental adjustments to the clock frequency fj tending to cause the steady state mean of the fill level Lxj, or its derivative, to move toward zero.

Title: Sanding devices and the like for removing materials
Inventor: PARROTT BRIAN H
IPC: B24D11/02
Filed: 1996-12-13
Abstract: Perforated sheet steel or wire mesh to which tungsten carbide grit is copper braze welded to provide a device which can be cut to a desired size and shaped into or used as a substrate for tools used for sanding, filing, grinding, deburring, deflashing, cutting, sawing, filing and the like. The sheet steel being perforated provides apertures or recesses wherein removed material can collect and/or pass through reducing the clogging of the grit and frequency of cleaning the working surface of the tool or device. The apertures also provide for the flow of air, cooling the device in certain applications. Tungsten carbide gritted wire mesh is particularly good in providing a surface which tends to renew itself due to grit adhering to the side of the wire strands but not such as to clog the holes.  Welding the grit to the wire mesh or cloth also causes the strands of the cloth to be welded together providing for a strong, yet flexible device or substrate.

Inventor: LARSON DONALD GLENN
IPC: H01S3/225
Filed: 1997-01-03
Abstract: A laser system support structure is provided having an independent, kineatically mounted chamber and optics platform. Swivel-type mounts are used to couple the platform at three points to the laser support frame, thereby allowing the platform to remain static while the support frame, via the swivel mounts, deflects around the platform in response to external forces. The independent platform design provides secondary benefits of creating a compartmentalization of laser system components, leading to a modular type design.  Each laser system module is mounted to the support structure on an extension rail, to allow removal of the module from the support frame for easy access during servicing.

Abstract: An intensity modulator (20) having a Mach-Zehnder structure with first and second waveguide arms (42, 44) formed of an electro-optic polymer (30). The active molecules of the waveguide arms are poled in first and second different and substantially orthogonal directions (82, 84). Electrodes (64, 66, 68) are arranged to receive a modulating voltage (70) and generate first and second electric fields which are respectively aligned with the first and second directions.

Other embodiments combine mode splitters and combiners with first and second Mach-Zehnder modulators which have electro-optic polymer waveguides. The active molecules of the arms of the two Mach-Zehnder modulators are poled in orthogonal directions.
