Abstract: A quick connect-disconnect fluid coupling assembly having cylindrical outer and inner coupling members (13, 84; 12, 82, 83), one of which is connected to a conduit and the other to a fluid conveying system. The assembly is accomplished by inserting a U-shaped locking member (14) having a bight (52) and two parallel legs (53, 54) into the outer member (13, 84), which has a peripheral slot (44) receiving the bight so that the curved portion (55) thereof does not extend beyond the periphery. Openings (50, 51) in this member (13, 84) receive the legs (53, 54), which are then locked around grooves (18) in the inner member (12; 82, 83) and the ends (73, 74) of the legs do not extend beyond the periphery of the outer member (13, 84). The outer portion (59) of the bight (52) is thinner than the inner portion (62) to permit easy insertion into, and withdrawal from, the slot (44) of the outer member. The system may also be utilized in an assembly of three or more components, wherein two or more locking members (14) are used.

IPC: H04W68/00
Filed: 2000-07-12
Abstract: METHOD AND APPARATUS FOR EFFICIENTLY PAGING      A MOBILE TERMINAL IN A WIRELESS NETWORK        A method for locating a mobile terminal in a wireless telecommunications network includes retrieving historical data associated with the whereabouts of the mobile terminal. The historical data is used to issue a paging signal to the mobile terminal to those base stations associated with the geographic areas in which the mobile terminal is most likely to be found. By intelligently issuing the paging signal, wireless telecommunications network resources are conserved while the likelihood of locating the mobile terminal is enhanced. A trace pattern database is updated each time a mobile terminal is located, or, in accordance with a predefined algorithm, is stored in the wireless telecommunications network. Advantageously, flexibility is provided to the wireless telecommunications service provider in determining the frequency with which the trace pattern database is updated and hence, the accuracy of the database.

Title: Stripper packer
Inventor: WIEDEMANN JIM
IPC: E21B33/068
Filed: 2000-07-25
Abstract: A stripper packer includes a main body having a first end and a second end. A passage extends through the main body from the first end to the second end, thereby facilitating the passage of coiled tubing through the main body when the coiled tubing is being stripped in and out of a well bore. A primary sealing element encircles the passage. A secondary sealing element encircles the passage. A piston is positioned within the main body. Movement of the piston in a first direction toward the first end of the main body applies a compressive force to the primary sealing element thereby causing the primary sealing element to expand inwardly to form a circumferential seal around the coiled tubing. Movement of the piston in a second direction toward the second end of the main body applies a compressive force to the secondary sealing element thereby causing the secondary sealing element to expand inwardly to form a circumferential seal around the coiled tubing.

Patent CA-2328089-A1 (CA)
Inventor: MELMAN PAUL
IPC: G02F1/055
Filed: 1999-04-08
Abstract: An optical modulator is provided to control the intensity of a transmitted o r reflected light. In a transmission mode, a separator splits arbitrarily polarized light into two polarization rays and one is made to travel a separate path from the other. A recombiner causes the two rays to recombine at an output unless an electro-optic phase retarder changes the polarization of  the two rays, in which case, both of them miss the output by an amount which  is a function of the voltage on the retarder. A normally-off version with lo w polarization mode dispersion is obtained by changing the orientation of the recombiner. A normally-on version with low polarization mode dispersion is obtained with a passive polarization direction rotation. Similar results can  be obtained in a reflection mode where the input and output are on the same side of the modulator. Versions using a GRIN lens are particularly suited to  modulation of light out of and back into fiber-optic cables. The device can be operated as a variable optical attenuator, an optical switch, or a high spee d modulator and is insensitive to polarization of the input light. A preferred  material for the phase retarder is a hot-pressed ceramic lead lanthanum zirconate titanate composition.

Inventor: BROWN TERRY L
IPC: F25B9/02
Filed: 1999-05-06
Abstract: A miniature refrigeration system and method of operation. A primary refrigerant is pressurized by a compressor (130) to a relatively low pressure, for safety reasons. The compressed primary refrigerant is passed through a primary-to-secondary heat exchanger (240), to precool the gas mixture. The secondary side of the primary-to-secondary heat exchanger (240) is cooled by a secondary refrigeration system. The primary refrigerant exiting the primary outlet of the primary-to-secondary heat exchanger passes to a primary Joule-Thomson expansion element (150) where the high pressure gas is expanded to a lower temperature. This low temperature gas cools a heat transfer element mounted in the outer wall of the catheter of cryoprobe, to cool surrounding tissue. Return gas can flow back through a distal primary-to-primary heat exchanger (160) to further cool the incoming high pressure gas mixture. A proximal primary-to-primary heat exchanger (140) can be added between the primary-to-secondary heat exchanger (240) and the primary compressor (130).

Abstract: A reservation method and system for limousine services and other surface transportation services of vendors which supply both a vehicle and a driver. Each vendor specifies when and where it will pick up and drop off travelers; the number and type of vehicles it has; the percentage of each type which is available for new reservations; and the manner (time and/or distance) in which its base price is to be determined.      Customer desired pickup and drop off locations are compared to those serviced by vendors to determine those vendors for which both the pickup and dropoff locations for a particular trip are within the region serviced by a single vendor, and whether the desired vehicle is available; and if so, the customer is advised accordingly, a corresponding reservation is booked, and the customer's credit card account is charged. Reservations are scanned to extract those for which corresponding pickup or dropoff times are within a specified number of hours in the future. Where a pickup place is an airport, the extracted reservations are cross-checked against status information respecting corresponding airline flights to determine those reservations for which a corresponding flight arrival time is delayed or advanced, or the flight has been diverted.      Reservation changes are made to reallocate vehicles of the same vendor, or to change the reservation to a different vendor, in accordance with such flight information changes and vehicle availability.

Abstract: An electrical connector has a non-conductive planar base defining a centrally located center aperture extending therethrough. The base has at least three generally identical sectors circumferentially arranged around the center aperture. Each sector defines a plurality of contact-receiving apertures extending through the base in a first direction perpendicular to the base. The contact-receiving apertures in each sector are organized into a plurality of rows. Each row in each sector extends along the base in a second direction with regard to such center aperture. The base is formed from an injection mold that includes a gate structure at the center aperture of the to-be-molded base. A non-conductive molding material is injected into the injection mold through the gate structure, whereby the injected material is generally evenly distributed into each sector of the base. The contacts are inserted into each contact-receiving aperture by mounting the base to a platform rotatable on an axis such that the base is perpendicular to the axis and such that the axis is coincident with the center aperture. The platform and the base mounted thereto are rotated to a first position wherein the field of view of a contact insertion device positioned adjacent the platform coincides with a first one of the sectors of the base, and the contact insertion device inserts a contact into each contact-receiving aperture of the first one of the sectors. Rotation and insertion are repeated for each additional sector.
