Title: Conductive via fill inks for ceramic multilayer circuit boards on support substrates
Inventor: PRABHU ASHOK NARAYAN
IPC: C09D11/00
Filed: 1996-01-29
Abstract: Conductive via fill inks for green tapes to be stacked and bonded to a support substrate, the glass used for the green tape having a firing temperature from 850-950 ° C, wherein the glass used for the via fill ink has a glass transition temperature that is higher than that of the glass used to make the green tape, preferably does not crystallize at the maximum firing temperature of the green tape and comprises from 30-75 percent by volume of the glass-conductive metal powder mixture of the via fill ink. These conductive via fill inks will not shrink until the green tape shrinkage has commenced during firing of the composite circuit board and they will flow slightly during firing, forming good bonds to the glass in the walls of the vias, thereby ensuring good integrity of the vias and good connections to the circuitry on the fired ceramic multilayer circuit board.

The valve housing (32) defines a valve seat (40) having a flexible diaphragm valve (56) which rests against the valve seat (40), and moves away from said valve seat (40) in response to pressure exerted thereon to permit flow of the body fluid from the peritoneum through the valve housing (32) and into the venous tubing (22).
Patent CA-2214897-A1 (CA)
Title: Broadband switching network
Inventor: SMITH AVRIL JOY
IPC: H04L12/54
Filed: 1996-03-08
Abstract: In a broadband switching system for the switching of asynchronously transferred cells of data, a dynamic bandwidth controller (DBC) controls the application of data cells at an input port of the system, the data cells being supplied by a number of transmitting end-stations.  The DBC detects incoming cells, identifies the source of the cells, provides buffering for the cells, and controls the output of the cells to the system switches according to a current cell rate (CR) assigned to the cells from the respective source. The system also includes a connection admission (CAC) module which determines bandwidth available in the system. The DBC and CAC operate together to maintain a permanent virtual path of a predetermined minimum bandwidth through the system and allocate additional bandwidth on demand up to a maximum. The additional bandwidth allocated to the path can be automatically removed or reduced of it is not used by the source.  Feedback to the source can be provided to prevent cells being supplied at a rate which would result in significant cell loss due to the limitation of bandwidth available for the path in the system.

Title: Method for attenuating surface wavetrains in seismic data
Inventor: KIM YOUNG C
IPC: G01V1/36
Filed: 1997-10-06
Abstract: A method for attenuating source-generated surface wavetrains in a set of seismicdata traces. According to the method, the seismic data traces are Fourier transformed with respect to time to determine the frequency components of the surface wavetrain. A phase matching operation is then performed using estimates of the wavenumbers for each of the frequency components to approximately align the surface wavetrain in the seismic data traces. Next, a spatial low-pass filter is used to remove the approximately aligned surface wavetrain. Finally, the phase matching is removed and an inverse Fourier transformation is performed to return the seismic data traces to the time domain.
Patent CA-2216494-A1 (CA)
Inventor: OLIVIER CHARLES
IPC: B60T17/22
Filed: 1997-10-01
Abstract: A wheel and brake monitoring system for a truck. The system is capable of detecting looseness of any wheel assembly or excessive brake travel. Looseness of a wheel assembly is detected by sensing lateral movement of the assembly or rotational movement between two wheels of that assembly. Looseness of a wheel assembly can alternatively be detected by sensing the change in position of the edge of a wheel rim, in relation to a fixed point on the supporting axle assembly. Brake travel is monitored by sensing excessive rotational travel of the slack adjuster associated with each axle. Excessive brake wear for an automobile can also be detected through the use of an embedded sensor wire within the brake pads or shoes.

IPC: H04M1/57
Filed: 1998-06-01
Abstract: The control software of a central office-installed ringback test device is augmented to allow a craftsperson to test the operability of a caller identification, call-waiting (CIDCW) class of service of a line, without participation of another technician at the central office. Rather than instructing the craftsperson to go back on-hook, the SASS's microcontroller maintains the trunk circuit through which the incoming call is coupled to the SASS in a suspended, continuously monitored state, so as to effectively busy out the calling line. The SASS then places a return call to the calling number by way of the ringback line, which by-passes the trunk, to the central office switch. If the line circuit from which the call is being placed is equipped with CIDCW class of service, the incoming call from the SASS will exercise its functionality - including providing a ringing signal back to the SASS, and an indication to the calling technician of another call, including the originating telephone number of that call - but it will not return a busy tone to the SASS. If the SASS receives busy tone, it knows that the line of interest is not properly equipped with CIDCW class of service.

The power piston applies the force to the vial piston to cause the v ial piston to force the liquid medication out of the vial. A cocking mechanism appli es force to the power piston to move the power piston against the force of the spri ng to engage the ratchets. A travel adjustment mechanism is moveable to position the spring within the power mechanism to control the movement of the power piston an d to thereby control the volume of liquid ejected from the vial.
