Title: Method of priming filter for molten metal
Inventor: MUNGER SERGE
IPC: B22D21/04
Filed: 2005-02-23
Abstract: A method is described for priming an in-line molten metal filtration unit having a porous ceramic or refractory filter mounted substantially horizontally in a filter box. This filter box has an inlet for molten metal and an outlet for molten metal, the outlet being a closeable outlet in an exit well connecting to the downstream side of the filter. The method of the invention comprises the steps of adding a molten metal to the filter box sufficient to entirely cover the upstream side of the filter with a depth of molten metal and temporarily sealing the outlet in the exit well. A steadily increasing vacuum is then applied to the closed exit well at a rate between 0.1 and 10 kPa per second by withdrawing a stream of air from the exit well by means of a fan or air venturi until molten metal begins to flow through the filter. At that point the vacuum is quickly released and the molten metal outlet is opened. Once the filter has been primed in this manner, flow of metal through the filter continues while requiring only a relatively low head of molten metal on the inlet side of the filter.

Abstract: An apparatus and method for converting a differential in thermal energy between a first thermal source having a thermal conducting fluid and a second thermal source having a thermal conducting fluid is provided. The apparatus emplys a first vessel and a second vessel. Each of the vessels contain a gas under pressure The vessels contain heat exchanging coils that are connected to the thermal sources by fluid lines. A plurality of cooperating valves regulate the flow of the thermal conducting fluid from the first and second thermal sources to the first and second vessels. The valves alternate between first and second operating positions. In the first position, the valves permit a flow of thermal conducting fluid from the first thermal source to the first vessel and from the second thermal source to the second vessel and prevent a flow of thermal conducting fluid from the first thermal source to the second vessel and from the second thermal source to the first vessel. In the second position, the valves permit a flow of thermal conducting fluid from the first thermal source to the second vessel and from the second thermal source to the first vessel and prevent a flow of thermal energy from the first thermal source to the first vessel and from the second thermal source to the second vessel. A pressure driven actuator in fluid communication with the first and second vessels is driven into reciprocating motion between a first position and a second position by alternating positive pressure and negative pressure from the first and second vessels.

Abstract: An assay test kit is used in a mouth rinse sample collection procedure involving collecting a mouth rinse sample from a patient. A neutrophil reactant diagnostic reagent is delivered to the rinse sample immediately after collection. Diagnostic reagents containing diammonium salts that are reactive with neutrophil enzymes are added to the sample to produce visually discernable colour change in the solution after a selected period of time. Most preferably, the reagents are selected to produce a colour change after a period of time. The reaction is then measured by comparing the resulting sample colour change by eye or mechanically to a standardized colour chart/swatch that correlates with predetermined neutrophil concentrations and/or periodontal disease levels.

Title: Processor-controlled variable gain cellular network amplifier
Inventor: BUREN V ALAN VAN
IPC: H04Q7/22
Filed: 2006-10-31
Abstract: A system and method for amplifying cellular signals and reducing interference introduced into a cellular network by the network amplifiers. The network amplifier includes an antenna configured to receive a downlink signal from a base station and a variable gain module for amplifying an uplink signal received from a handset.  The variable gain module applies an amplification factor to the uplink signal to generate an adjusted uplink signal to be transmitted to the base station via the antenna.  A processor is used for determining a value of the amplification factor, where the value of the amplification factor is a function of a level of the downlink signal. The amplification factor may be selected so that interference introduced into a cellular network by the transmission of the adjusted uplink signal is substantially eliminated.

Title: Vehicle bumper beam
Inventor: LYONS BRUCE W
IPC: B60R19/04
Filed: 2005-06-23
Abstract: A bumper beam includes an open front section made from a high-strength material such as ultra-high-strength steel material, and further includes a mating back section made of lower-strength material attached to a rear side of the front section along abutting flanges. The front and back sections combine to define different tubular cross sections. The front section can be roll-formed, and the back section can be stamped, thus taking advantage of roll-forming processes' ability to form high-strength materials, while allowing the back section to have a more complicated shape and be stamped. The abutting flanges telescopingly overlap in a fore-aft direction of the vehicle and are welded together at locations that potentially experience shear upon impact, but the flanges of the front section are captured within the flanges of the backs section, thus providing impact strength even if the attachment locations shear off

Abstract: A method and system for providing secure access to a device initiating communications using a peer-to-peer signaling protocol, such as a SIP or H.323. In a device registration phase, the device contacts a secure access server, and authenticates to the secure access server by providing an identification, such as its factory ID. The secure access server then issues a device ID and private key to the authenticated device. A client can then initiate a further communication session and be authenticated by the secure access server. The secure access server returns the device identification and the device's public key to the client. The client and device can then perform a symmetrical key exchange for their current communication session, and can communicate with appropriate encryption. The device's private key can be set to expire after one or more uses.

Abstract: A double stage isolator is disclosed formed of a face-to-face slabs or sheets of materials that will suitably split, combine, non-reciprocally rotate to ensure isolation in a reverse direction from output ports to respective input ports of any light launched into the input ports. A right angled Porro-prism is disposed at an end of the affixed together slabs having planar faces to direct light launched in a folded fashion to the output ports. This isolator is suitable to be used in planar lightwave circuits (PLCs) and other waveguide applications as the input and output ports are on a same end of the isolator and lie along a same line in a linear array. A half waveplate is used in addition to beam splitter combiners and non--reciprocal rotators means that rotate the light by 90 degrees. This half waveplate is disposed to pass a single beam in a forward propagating direction and to interchange the polarization of two sub-beams that pass through from an output port to an input port in a reverse direction.
