Title: Method and apparatus for no touch tagging of cement plugs used in well abandonment
Inventor: STEELBRAND DAVID
IPC: E21B33/138
Filed: 1994-07-22
Abstract: Abandoned wells are typically sealed by cement plug means to prevent groundwatercontamination. In most cases the placement and competence of the cement plugs are regulated by various government agencies and tagging of the plugs to verify depth and competence is normally a requirement of such agencies. Current tagging methods include lowering the drill string to the top surface of the plug. This method entails a considerable amount of waiting time for the cement to set-up and high costs associated with such wait-ing time. A new method of tagging well plugs is comprised of a plurality of ultrasonic transducers arranged in transmit/receive pairs to form a plurality sensor which is incor-porated into a conventional  drill string collar and, when activated, provides a measure-ment of the distance from the upper surface of the cement plug to the bottom of the collar thus verifying that the plug is in fact where it is supposed to be and at the correct depth. Since no mechanical contact with the plug is required the need to wait for cement set-up is significantly reduced and with it the attendant costs.

Title: Method and system for buffer occupancy reduction in packet switch network
Inventor: CIESLAK RANDALL A
IPC: H04L12/56
Filed: 1994-11-09
Abstract: A packet switch system having a buffer occupancy reduction mechanism for controlling  data  flow  through  switched  nodes  of  the  system  to  avoid congestion  and  reduce  required  buffer  storage  at  the  nodes.  For  an isochronous connection, buffers are initially allocated at each switching node  connection  to  ensure  listless  transmission  of packets.  A buffer occupancy trace for the connection is recorded and the delay time of an isochronous packet at a particular switch port is returned to a preceding switch port. The preceding switch port employs the feedback message to delay subsequent packets through the connection to reduce the queuing time at the particular switch port.  Once the isochronous connection has stabilized, buffer reallocation is performed wherein a scheduler at each switch node along the connection attempts to combine buffer allocations for different isochronous  connections.  This  occurs provided the  corresponding buffer occupancy traces of the  isochronous connections do not overlap.  Buffer occupancy  reduction  is  therefore  accomplished  through  the  delaying  of isochronous packets propagated through the connections of the packet switch system and the reallocating of buffers initially assigned to two or more isochronous connections.

Title: Inverter for electroluminescent lamp
Inventor: SANDERSON STEPHEN J
IPC: H05B44/00
Filed: 1995-05-23
Abstract: A circuit for providing AC power to an electrolumines-cent lamp powered by a battery comprises a high frequency oscillator through a control to drive a fly back voltage regulator comprising an inductor powered by a relatively low battery voltage and coupled to ground through a switch-ing  transistor.   A capacitor coupled  to  the  inductor through a diode is charged by the repetitive charge and discharge of the inductor when the transistor is switched ON and OFF at high frequency by the high frequency oscilla-tor.  The charge in the capacitor is dithered about a high DC voltage, such as 100 VDC, by sensing the charged voltage for periodically turning the transistor ON and OFF accord-ingly.  A bridge circuit receives two pairs of like lower frequency square wave pulse signals of opposite polarity from a low frequency oscillator.  Each signal is applied to a different one of two series connected legs of two oppo-site like branches, each branch coupled between the high DC voltage and ground, each leg containing two switching FET transistors and a current source.   An electroluminescent lamp is connected between the legs in each branch.  One of the legs in each branch is alternately turned ON and the other leg turned OFF by the square wave signals to provide the equivalent of an AC signal to the electroluminescent lamp in opposing directions, thereby doubling the value of the peak stepped up DC voltage.

Patent CA-2154445-A1 (CA)
Inventor: AUGUST J THOMAS
IPC: C07K19/00
Filed: 1994-01-21
Abstract: The inventors have discovered a targeting signal that will direct proteins to the endosomal/lysosomal compartment, and they have demonstrated that chimeric proteins containing a luminal antigenic domain and a cytoplasmic endosomal/lysosomal targeting signal will effectively target antigens to that compartment, where the antigenic domain is processed and peptides from it are presented on the cell surface in association with major histocompatibility (MHC) class II molecules.  Chimeric DNA encoding the antigen of interst, linked to an endosomal/lysosomal targeting sequence, inserted in an immunization vector, can introduce the chimeric genes into cells, where the recombinant antigens are expressed and targeted to the endosomal/lysosomal compartment. As a result, the antigens associate more efficiently with MHC class II molecules, providing enhanced in vivo stimulation of CD4+ T cells specific for the the recombinant antigen.  Delivering antigens to an endosomal/lysosomal compartment by means of chimeric constructs containing such lysosomal targeting signals will be of value in any vaccination or immunization strategy that seeks to stimulate CD4+ MHC class II restricted immune responses.
