Patent CA-2224037-A1 (CA)
Title: Solvent deasphalting unit capable of generating power
Inventor: HOOD RICHARD L
IPC: C10C3/08
Filed: 1997-12-08
Abstract: Solvent deasphalting apparatus includes a separator that receives two inputs, a heavy hydrocarbon feed and a solvent feed; and the apparatus produces two outputs, an asphaltene/solvent stream and a deasphalted oil/solvent stream. A solvent recovery unit of the apparatus receives the two output streams and produces mainly a substantially solvent-free deasphalted oil product stream, a substantially solvent-free asphaltene product stream, and a recovered solvent stream which is returned to a solvent drum. A pump pumps a substantially constant volume of solvent from the solvent drum into a by-pass line connecting the pump to the solvent drum, and into a connection line connecting the pump to the separator. The amount of solvent flow in the connection line is functionally related to the level of heavy hydrocarbon feed so that solvent in excess of that flowing into the connection line and spills back to the solvent drum through the by-pass line. Finally, a power generator generates power in response to the flow of solvent in the by-pass line. The power generator includes a vaporizer for vaporizing solvent in the by-pass line, an organic vapor turbine responsive to vaporized solvent for expanding the vaporized solvent and producing expanded vaporized solvent, and generating power, a condenser for condensing the expanded vaporized solvent and producing condensed solvent, and a pump for returning the condensed solvent to the drum.

Title: Oscillating table, in particular for use in a continuous casting machine
Inventor: DEGRANDE HUBERT
IPC: B22D11/04
Filed: 1996-08-23
Abstract: The oscillating table (1) comprises a movable part (5) on which a mould of a continuous casting machine is located. The movable part is coupled via eccentrics (13) to a driving mechanism for introducing an upward and downward oscillation motion in order to prevent the cast steel from remaining stuck to the wall of the mould. In contradistinction to the known oscillating tables according to the invention the eccentrics (13) are not uniformly driven. To this end the driving mechanism comprises driving means for driving the eccentrics (13) with a non-uniform angular speed. In a preferred embodiment the driving means comprise hydraulic motors (19) provided with a control system (29). The hydraulic motors (19) are electronically synchronised and as a safeguard being coupled to each other by a synchronisation shaft (33). In this way the facility is obtained to operate any lifting and descending motion of the casting mould.

IPC: G01N33/543
Filed: 1998-04-29
Abstract: Disclosed is a method for determining the concentration of an analyte in a sample of body fluid.  The method involves contacting the body fluid sample with a test strip containing mobile,  labeled  specific  binding  partner  for  the  analyte, through which strip the test fluid, analyte and any complex formed by  interaction of  the  analyte  and  labeled  specific binding partner therefore can flow by capillarity.  The strip contains at least one zone for capture of the labeled specific binding partner and at least one separate zone for retention of the analyte/labeled specific binding partner complex.   By determining the magnitude of the signal from the detectable label in the capture zone(s) and retention zone(s) and determining a final response signal by correlating signals using an algorithm and number of zones chosen in a manner that provides a final response signal best suited for the particular assay, the  concentration  of the  analyte  can  be  determined  with greater precision.

Title: Mechanism for dispatching packets via a telecommunications network
Inventor: BANCILHON HERVE L
IPC: H04L12/56
Filed: 1998-09-30
Abstract: A mechanism for dispatching a sequence of packets via a telecommunications network includes a queue for packets for transmission and a queue controller responsive to receipt of a new packet for transmission to compare parameters of the new packet to parameters of any packet already in the queue, the queue controller determining whether to queue or drop the new packet depending on the result of the comparison(s). The queue can be implemented as a linked list of packet entries with individual pointers to the respective packets concerned. The queue entries can include details relating to the packet including data relating to the information flow and also the packet identity. In a TCP environment, the flow information can include the source IP address and the source TCP port, as well as the destination IP address and the destination TCP port. The identity information can include sequence numbers and acknowledgement numbers for the packet concerned. In order to optimize network usage, it can be useful to drop some packets at a routing node. A decision to drop a packet can be made if the new packet and a queued packet relate to the same information flow, the new packet sequence number equals the queued packet sequence number and the new packet acknowledgement number is less than the queued packet acknowledgement number. The new packet is dropped where the new packet is a retransmission of a queued packet and the length of the queued packet is greater than or equal to that of the new packet. A queued packet is replaced by a new packet when the new packet is determined to be a retransmission of the queued packet and the length of the new packet is greater than that of the queued packet.

IPC: A01M1/14
Filed: 1997-03-11
Abstract: An insect trap (400) using attractant light, comprising a source of insect attractant light and a housing (404) that can be mounted on a generally planar or flat mounting surface. The housing (404) and the source of light cooperate to form a bidirectional or a multidirectional (overlapping or non-overlapping) pattern of insect attractant light. The housing comprises one, two or more openings for the insect attractant light (401) that is reflected and radiated onto the flat mounting surface. The housing and the source of insect attractant light can cooperate to form a light pattern directed in a continuous display pattern that can surround the housing. The housing openings further facilitate the entry of flying insect pests into the trap. As the insects enter the trap, they are immobilized on an insect immobilization surface mounted within the trap. Cooperation between the direct radiant light, reflected light and the position of the housing and insect immobilization surface forms at least two (preferably non-overlapping) light displays that can substantially increase capture rates when compared to prior traps. The trap can also display a light pattern substantially surrounding the trap housing.

Abstract: Improved solar cell circuit layouts and cell structures that protect solar arrays located on spacecraft disposed in geosynchronous earth orbit from electrostatic discharge. An insulating material, such as RTV adhesive, for example, is used as a barrier that disposed in intercell gaps between solar cells. The use of the insulating material modifies sparking in the gaps caused by electrostatic discharge so that, while the spark still occurs, it has different non-destructive characteristics. The use of the insulating material causes no damage to other solar cell materials, such as a Kapton insulating layer or substrate used to support the solar cells. Furthermore, unique solar cell wiring schemes are provided that limit the voltage between adjacent solar cells to 50 volts or less.
