Title: Method for the removal and recovery of mononuclear and polynuclear aromatic co-products produced in a hydrocarbon dehydrogenation reaction zone
Inventor: GLOVER BRYAN K
IPC: C07C7/12
Filed: 1998-08-03
Abstract: Polynuclear aromatic compounds (PNA's) produced as a by-product in a hydrocarbon dehydrogenation zone are removed and recovered by admixing the effluent from the dehydrogenation zone with a recycle stream containing mononuclear aromatic compounds (MNA's) and the resulting admixture is contacted with an adsorbent to reduce the concentration of MNA's and PNA's and to produce a stream comprising dehydrogenated hydrocarbons and dehydrogenatable hydrocarbons. The spent adsorbent recovered from the adsorption step containing MNA's and PNA's is regenerated by contacting with a hot hydrogen-rich gas to recover at least a portion of the MNA's and PNA's and to thereby regenerate the spent adsorbent. The hydrocarbon-containing effluent from the regeneration step is then separated into a MNA's -containing stream and a PNA's-containing stream and at least a portion of the MNA's-containing stream is recycled to the mixing step.

IPC: G01S7/00
Filed: 1997-06-26
Abstract: An object in a storage area (12s) or moving vehicle is monitored by attaching an electronic tag (16s) to the object. An electronic device (13) detects the presence of the object by communicating with the tag while the object is in storage or is being moved by the vehicle, The tags may also determine the location of an attached object and may reroute the object if it deviates from a given shipping schedule. A group of objects is monitored by two electronic tags, each attached to an object in the group. Each tag has circuitry for communicating information relating to an object in the group to a second tag. Each tag also includes a memory connected to the circuitry that is capable of storing the information, and a controller connected to the memory and the circuitry.

Title: Pneumatic hammer drilling assembly for use in directional drilling
Inventor: KONSCHUH CHRISTOPHER W
IPC: E21B17/10
Filed: 1999-02-03
Abstract: A drilling assembly and a method for directional drilling using the drilling assembly. The drilling assembly comprises a drilling bit, a near bit stabilizer and an adjustable gauge stabilizer. The near bit stabilizer is located a first axial distance from a distal end of the drilling assembly and has a near bit stabilizer gauge which is greater than a nominal drilling assembly gauge. The adjustable gauge stabilizer is located a second axial distance from the distal end, which is greater than the first axial distance, and is adjustable between an extended and retracted gauge. The retracted gauge is less than the near bit stabilizer gauge. A bit drop angle is created between the drilling assembly and the drilling bit, while a stabilizer angle is created between the near bit stabilizer and the adjustable gauge stabilizer.  The combination of the bit drop angle and the stabilizer angle results in a net build angle of the drilling assembly, when the adjustable gauge stabilizer is adjusted to the retracted gauge, and a net drop angle when adjusted to the extended gauge.

Patent CA-2266257-A1 (CA)
Title: Circuit breaker with an anti-lift pivot handle
Inventor: GULA LANCE
IPC: H01H71/52
Filed: 1999-03-22
Abstract: A circuit breaker handle is provided with a curved bearing surface at its pivot point. The handle bearing surface has a substantially constant radius and is connected to the body of the handle with a necked down handle extension. The handle extension has a width that is less than the width of the curved bearing surface at the point of connection between the bearing surface and the necked down region. The handle pivot mates with a corresponding bearing surface on a notch in the side plate that it pivots within. The arc of the curved bearing surface in the side plate is greater than that of the corresponding bearing surface on the handle and captures the handle pivot within the notch in the sideplate, so the handle cannot lift off the bearing surface on the notch as it is moved.
Patent CA-2266951-A1 (CA)
Title: Method and apparatus for adjacent service area handoff in communication systems
Inventor: SCHIFF LEONARD N
IPC: H04W36/14
Filed: 1997-09-23
Abstract: A handoff technique in which system users detect transitions in service between a current service area (B10, S4) and an adjacent service area (B2, S5), and request a forward link channel in the new service area (B2, S5) when a detected signal strength for the new service area exceeds predetermined threshold levels. The forward communications link in the current service area is maintained until the strength of the new service area signal (B2, S5) reaches a certain level and appropriate channel quality is confirmed, as based on various known criteria. Typically, service area transitions are detected using the signal strength of pilot or paging signals associated with service areas, which are used to determine a relative signal strength of new service area signals. Pilot signal level adjustments used to counter roll-off effects are detected and compensated for in comparing signal levels.  To minimize the burden on system resources, new service area signals are not selectable until a minimum time has passed, or a minimum change in energy from a prior pilot signal is detected. In addition, communications using the previous service area can be dropped almost immediately upon engaging the new service area.

Abstract: A method and apparatus is disclosed for the sterilization of flowable solids using a microwave treatment unit. The flowable solids might be from a waste treatment system or the like and might either be dry flowable solids or might alternatively be fluid born which would also yield them flowable through the device. The application of microwave treatment for a period of time sterilizes the solids. The method and apparatus might also be further modified to include apparatus and process for the removal of water or other fluid from a fluid born solid in advance of sterilization. The apparatus of the present invention might be attached directly to a pressurized waste water treatment system. Sterilized solids are released from the unit for removal and disposal.

Abstract: A distributed telecommunications switching subsystem (100) receives and distributes data packets passed between a plurality of switching subsystems or channel banks (102, 104, 106) and a data packet switch (110). Each channel bank (102) has a stored list of addresses. When a channel bank (102) receives a data packet, it compares the address of the data packet to its stored list of addresses, and transmits the data packet to another channel bank (104) if the address of the data packet does not correspond to any of the addresses in its stored list of addresses. The data packet is passed on until it reaches a channel bank (106) with a matching address or else it is appropriately handled by a last channel bank (106) in the chain. If the address of data packet matches an address in its stored list of addresses, the channel bank (102) passes the data packet through a subscriber interface card (120) to a customer premises equipment unit (108) corresponding to the address of the data packet.
