Title: Flange section
Inventor: BARTLETT JAMES LELAND
IPC: G01L7/08
Filed: 1996-05-02
Abstract: A flange assembly for joining together housing sections having a resilient diaphragm element disposed therebetween. The flange assembly is comprised of a first flange on a first housing section having a first compression surface and a second flange on a second housing section adapted to be joined with the first flange. The second flange is formed of a deformable metal and has a second compression surface facing the first compression surface and a flange extension dimensioned to wrap around the peripheral edge of the first flange and to be crimped thereon. A spacing element is disposed on the peripheral edge of the first flange between the first and second flanges to maintain a predetermined spacing between the first compression surface and the second compression surface. The spacing is slightly less than the thickness of the resilient diaphragm element so as to compress and seal same between the compression surfaces. The flange extension is crimped onto the first flange such that the surface contact betweenthe flange extension and the first flange is primarily in the vicinity of the spacing element.

Title: Method for making a multilevel polyimide stencil
Inventor: CARROLL KEITH C
IPC: H05K3/12
Filed: 1996-10-31
Abstract: A method of using a laser to cut a groove or pocket of predetermined depth of less than about 0.005 inches in a stencil comprising a polyimide sheet having a thickness in the range of 0.005 to 0.012 inches comprising the steps of mounting the stencil on a movable work table and positioning and maintaining a laser a predefined distance from the polyimide sheet above the work table. A laser beam is directed against the polyimide sheet to cut an indentation into said polyimide sheet. The laser beam has a pulse duration and a power level to make the cut into the polyimide sheet. The method further includes the step of directing a gas against the polymide sheet where the laser beam cuts into said polyimide sheet. The gas is pressurized. The depth of the indentation cut into the polyimide sheet by the laser is determined by choosing the pressure of the gas relative to choosing the pulse duration and the power level of the laser beam. The work table is moved relative to the laser whereby the indentation cut into the polyimide sheet creates a groove or pocket as the laser beam moves across the polyimide sheet. By controlling the pressure of the gas normally used to remove dross from the cut edges of the material, the cutting process can be better controlled so that laser milling of polyimide sheet is reliably obtained.

Patent CA-2196634-A1 (CA)
Inventor: WU PETER T
IPC: G01V3/30
Filed: 1997-02-03
Abstract: A well logging method and apparatus are disclosed for determining borehole corrected formation resistivity, borehole diameter, and borehole fluid (mud) resistivity with improved accuracy.  A logging device in the borehole transmits electromagnetic energy from a transmitter, which energy is received at receivers on the logging device.  The phase and amplitude of the received energy are measured at the receivers and a phase shift, phase average, and attenuation are associated with the transmitter-to-receivers spacing.  The process is then repeated for a plurality of further transmitters having different spacings from the receivers.  A formation and borehole model having model values of borehole corrected formation resistivity, borehole diameter, and borehole fluid resistivity is generated.          Values of borehole corrected formation resistivity, borehole diameter, and borehole fluid resistivity that would produce a model phase shift, phase average and attenuation corresponding to the measured values of these parameters are then determined.

Patent CA-2197282-A1 (CA)
Title: Granular media filter including media settler assembly
Inventor: BISKNER CHARLES D
IPC: B03D1/14
Filed: 1997-02-11
Abstract: A granular media filter including a settler assembly for reducing media loss during high-turbulence washing of media in the granular media filter. The settler assembly is comprised of plates, tubes, or other porous materials placed between a system of baffles and a conventional backwash trough. The settler assembly reduces turbulence near the overflow weir edge of the backwash trough, thereby reducing media carry over with the backwash water into the backwash trough. The trough baffle settler assembly will allow higher backwash rates per backwash with the same or lower media losses than experienced with previous trough-baffle designs, thereby reducing costs of construction and operation of granular media filter systems. The settler assembly is particularly adapted for use with granular media filters employing simultaneous application of air and water to produce a high turbulence backwash.

Title: Digital mobile communication system
Inventor: LEHTIM KI MATTI
IPC: H04W88/18
Filed: 1995-11-21
Abstract: The present invention relates to a digital mobile communication system in which mobile stations (MS) and the fixed network comprise speech coders. The speech coders of the fixed network are located remote from the base stations (BTS) in transcoders (TRCU). In MMC calls, however, the transcoders are controlled to operate so that the frames received from a first base station (BTS) are forwarded with minor modifications through a pair of tandem connected transcoders to a second base station, without carrying out any speech encoding or decoding in the transcoders. Consequently, speech coding is only carried out in the mobile stations, and the speech parameters are simply passed through the mobile communication network, resulting in a significant improvement in the speech quality as compared with the conventional tandem coding.

Patent CA-2208686-A1 (CA)
Title: Improved flow regulator
Inventor: PALMER DAVID W
IPC: F24F11/75
Filed: 1996-01-16
Abstract: A regulator including a movably, preferably hingedly, mounted member having a distal face (51), exposed to a reference pressure, and a frontal face (52), exposed to fluid passing through the regulator.  Attached to the member (5) is a structure that variably impedes fluid flowing through the regulator. The amount that this structure impedes the fluid flow varies as a function of the difference between the pressure of fluid on the frontal face (52) of the member (5) and the reference pressure. The impeder may be an integral part of the piston extending into the path of the fluid flowing through the regulator, or it may be a separate structure attached to the member (5). As the member (5) moves in response to changes in pressure differential across the piston each movable segment is displaced with respect to its corresponding fixed segment. As the corresponding segments are further displaced with respect to each other, the impedance to flow increases. A restoring force or torque exerts a force on the member so as to tend to lessen the resistance on the fluid flow, and so that when there is no flow through the passageway the resistance is relatively low.  The member (5) may be mounted at the top of the regulator in order to make the regulator easy to clean and maintain. A dashpot (25) may be included in the regulator so as to reduce high-frequency oscillations that may occur in a finely tuned regulator. The regulator may include a bypass channel that permits a portion of the flow to bypass (60) the impeder. A variable throttle valve (65) mounted in the bypass channel (60) is used to adjust the effect of the bypass channel (60).

Abstract: In a telephone network having a plurality of network nodes, each having a unique network address and using out-of band signalling for call setup and routing, a method is provided for the routing of calls to a "ported" directory number which has been ported from a donor network node to a recipient network node. The method comprises the steps of (i) routing the call, using the ported directory number as the Called Party Number, from an originating network node towards the donor network node; (ii) intercepting the call at an intermediate network node between the originating network node and the donor network node, through which intermediate network node calls to the donor network node must pass; (iii) converting the ported directory number to a network address of the recipient network node; (iv) routing the call to the recipient network node using said network address; and (v) at the recipient network node, completing the call to the ported directory number.
