Title: Method and apparatus for full width ultrasonic bonding
Inventor: KLEMP PAUL GORDON
IPC: B29L7/00
Filed: 1997-11-25
Abstract: This invention relates to apparatus and methods for fabricating a web or consolidating web precursor material in fabricating a web. The invention comprises ultrasonic bonding apparatus including an anvil roll (20) receiving web materials thereon and receiving first (24a) and second (24b) rotary ultrasonic horns. The rotary ultrasonic horns (24a, 24b, 24c, 24d), in combination with the anvil roll, ultrasonically bond segments of e.g. first and second webs to each other. Third (24c) and fourth (24d) rotary ultrasonic horns spaced about the circumference of the anvil roll, in combination with the anvil roll, ultrasonically bond other segments of the webs to each other. The full widths of the webs can be ultrasonically bonded using the rotary ultrasonic horns. An outer surface of the anvil roll preferably carries a bonding pattern defining the locations where bonding of the webs occurs. Additional e.g. third and fourth webs can be bonded by the ultrasonic bonding apparatus. Such bonding can occur after first and second webs have been bonded to each other by first and second rotary ultrasonic horns. In some instances, the third and fourth rotary ultrasonic horns can ultrasonically bond portions of the first and second webs that have already been bonded together by one or both of the first and second rotary ultrasonic horns. In other embodiments, multiple repeat bonding of substantially the same segment of the web can occur. In still other embodiments, a batt of bondable material such as fibers can be consolidated by ultrasonic bonding with rotary ultrasonic horns to form a unitary web. The apparatus can operate at web speeds greater than 1000 feet/minute.

Title: Flow responsive time delay pump motor control logic
Inventor: RASMUSON GORDON L
IPC: F04D25/06
Filed: 1999-05-18
Abstract: An automatically controlled fluid flow responsive method and apparatus for achieving speed control or de-energization of an electric motor operatively connected with a downhole pump being connected to a production tubing string of a well when flow from the downhole pump becomes abnormally low. A selective electronic motor control signal is programmed, representing a selected minimum acceptable rate of discharge flow from the downhole pump. A flow transducer measuring flow through a pump discharge line provides an electronic flow related signal to the logic circuitry, representing actual pump discharge flow, which if below a predetermined value, initiates a preset timing sequence of the logic circuitry. When the flow related signal remains less than the motor speed adjustment setting for the duration of the time delay period the control circuitry will alter the electrical power supply to the pump motor and cause the motor to operate at any one of a number of lower speeds. The time delay motor control logic is provided with an adjustable "set flow" logic and an adjustable "motor control or cut-off delay" logic which establish parameters of allowable minimum pump discharge flow and the time period that the pump will be allowed to operate below a preset minimum allowable flow rate. When the preset "minimum flow" and "time period" settings are met the control logic will provide a control signal to alter or de-energize the electrical power circuit of the pump motor, thus slowing the pump to any of a number of lower speeds or shutting down the pump. The pump motor control logic incorporates a start-up delay which maintains the pump control logic in a deactivated state for a period of time which is selected to permit the well production system to reach its optimum flow rate.

Patent CA-2275915-A1 (CA)
Title: An apparatus for protecting connectors on circuit packs
Inventor: PATEL NARESH C
IPC: H04B10/2581
Filed: 1999-06-22
Abstract: A protection assembly for connectors is included on a circuit pack to prevent damage caused when a connector is removed while signal power is still being supplied to the circuit pack. More specifically, the protection assembly is disposed on the front side of the circuit pack to prevent access to the connector until signal power is automatically cut off from the circuit pack. In one embodiment, the circuit pack is the type having a lever arrangement capable of causing the circuit pack to engage and disengage the backplane of an equipment frame. When the circuit pack is engaged in the backplane, signal power is supplied through the connector that is accessible, for example, on the face plate of the circuit pack. The protection assembly includes a first shield member mounted on the face plate of the circuit pack in a location adjacent to the connector.  The protection assembly further includes a second shield member mounted or otherwise formed on the lever arrangement. When the circuit pack is engaged in the backplane, the first and second shield members cooperate to prevent access to the connector protected thereunder. To expose the connector, a technician would have to operate the lever arrangement to separate the first and second shield members. Because the circuit pack is disengaged from the backplane by action of the lever arrangement, signal power supplied to the connector is therefore automatically cut off before the first and second shield members are separated to expose the connector.

Title: A coherent combining/noncoherent detection (ccnd) method and apparatus for detecting a pilot signal in a wireless communication system
Inventor: XIAO-AN WANG
IPC: H04B1/7115
Filed: 1999-09-17
Abstract: A method and apparatus are disclosed for detecting a pilot signal in a wireless receiver using coherent combining/noncoherent detection (CCND) techniques. Coherent combining/noncoherent detection (CCND) techniques are used to detect the pilot signal whenever the receiver is already frequency locked, or otherwise known to have a small frequency offset. Conventional noncoherent combining/noncoherent detection (NCND) techniques are utilized to initially acquire the timing of the forward channel. Once the receiver is frequency locked, coherent combining/noncoherent detection (CCND) techniques may be used to continuously detect the pilot signals. After the receiver is frequency locked, the residue frequency error is small over several consecutive correlator outputs. The correlator outputs can thus be combined coherently (since the frequency error is known to be small), and the phase dependency is then eliminated by noncoherent detection. The disclosed coherent combining/noncoherent detection (CCND) technique can be extended to the case where the accumulation length, L, is too large such that coherent combining over L correlator outputs will have significant degradation even when the frequency error is small. In this case, the L outputs can be broken into M groups each of which contain L1 outputs, such that L = ML1.

Inventor: LEGRAND YVES
IPC: A61K38/49
Filed: 1998-04-27
Abstract: The present invention relates to gene therapy for the treatment of tumors. The invention more particularly relates to introduction of a gene encoding an anti-angiogenic factor into cells of a tumor, for example with a defective adenovirus vector, to inhibit growth or metastasis, or both, of the tumor. In a specific embodiment, delivery of a defective adenovirus that expresses the amino terminal fragment of urokinase (ATF) inhibited growth and metastasis of tumors. These effects were correlated with a remarkable inhibition of neovascularization within, and at the immediate vicinity of, the injection site. Delivery of a defective adenovirus vector that expresses kringles 1 to 3 of angiostatin inhibited tumor growth and tumorigenicity, and induced apoptosis of tumor cells. The invention further provides viral vectors for use in the methods of the invention.

Title: Integrating optical adm filters
Inventor: SOLHEIM ALAN GLEN
IPC: H04J14/02
Filed: 1999-11-10
Abstract: An OADM filter is integrated into the optics package of optical receivers and transmitters of a wavelength division multiplexing (WDM) network. As the transmitter and the receiver already use collimated optics, eliminating several lenses and fiber attachments with their associate alignment, as well as the physical enclosure, importantly reduces the price of the transceiver-ADM filter combination in comparison with the cost for a separate transceiver and ADM filter. Furthermore, the arrangement allows for a more flexible network growth.
