Patent CA-2290028-A1 (CA)
Title: Spoiler for wings
Inventor: FILSEGGER HERMANN
IPC: B64C9/16
Filed: 1999-11-18
Abstract: There is disclosed a spoiler for wings, in particular of planes, which spoiler is unfoldable during the landing and take-off of the plane or the like and retractable during cruising. In order to provide for enhanced aerodynamic conditions during landing and taking off without deteriorating the aerodynamic conditions during cruising, a structural member preferably made of a composite material and, in particular, carbon fiber reinforced plastic is arranged on the trailing edge of the spoiler, viewed in the direction opposite to the flight direction. The structural member, during landing or taking off, in the unfolded state of the spoiler with the landing flaps extended reduces the gap formed between the trailing edge of the spoiler and the surface of the landing flap and, during cruising, with the landing flap pulled in and the spoiler retracted abuts on the surface of the landing flap.

Title: Automated payment system and method
Inventor: JOHNSON BARBARA S
IPC: G06Q20/00
Filed: 1998-06-26
Abstract: Systems and methods for automated payment involve utilizing consumer payment authorization, clearing, and settlement systems to allow a merchant to reduce or eliminate an amount owed to another entity for services, products, and/or cash advances provided to the merchant.      After a customer identifier (e.g., a credit, debit, smart, charge, payment, etc. card account number) is accepted as payment from the customer, information related to the payment is forwarded to a merchant processor. The merchant processor acquires the information related to the payment, processes that information, and forwards at least a portion of the payment to a receiver as payment for at least a portion of the amount owed by the merchant. The receiver receives the portion of the payment forwarded by the merchant processor and applies that portion to the amount owed by the merchant to reduce or eliminate that outstanding amount.

Abstract: A method for repairing worn brake assembly holes on a highway trailer axle assembly including a cam shaft hole, and first and second anchor pin holes and including an axle stub extending from an end thereof, comprising the steps of aligning a boring tool, having a tool axis, with each brake assembly hole axis by aligning the tool axis parallel with the stub axis; positioning the tool axis at a distance from the stub axis equal to the distance of the brake assembly hole axis from the stub axis; and positioning the tool axis at an angular position relative to the brake assembly hole axis that is equal to the angular position of the brake assembly hole axis relative to the axis of another of the brake assembly holes. The aligned boring tool is then driven to bore an oversize hole through the worn brake assembly hole such that the worn brake assembly hole, including any worn extremities thereof, is consumed by the oversize hole, leaving a substantially cylindrical oversize hole. An oversize bushing is installed in the oversize hole having an inner diameter suitable to accommodate a brake cam shaft or anchor pin therethrough. An apparatus is also provided.

Patent CA-2313925-A1 (CA)
Inventor: ABDULNOUR JAWAD
IPC: H01P1/208
Filed: 2000-07-17
Abstract: A method and apparatus for reducing the size of microwave (or millimeter wave) dielectric resonator filters and for tuning the filter by inserting tuning screw within the dielectric itself. The filter includes a metallic housing that encloses a plurality of cavities, and each cavity contains a dielectric resonator whose top and bottom surfaces are flush with the top and bottom walls of the metallic structure. Due to the continuity and uniformity of the electric field generated in the y-axis of the dielectric, the filter's performance response becomes independent of height. This novel design allows for substantial reduction in cavity size without appreciably dropping the Q factor. Such continuity and uniformity of the electric field also allows for openings to be made parallel to the y-axis and inside the dielectric resonator, wherein tuning screws are inserted to selectively adjust the frequency. Other aspects of the invention include alternative methods for electromagnetic coupling in, within, and out of the filter; methods for reducing the machining accuracy by creating a small air gap at one end of the resonator; and methods for reducing the propagation of high modes by alternating the shapes or orientation of the resonators within the filter.

Title: Apparatus and method for optimizing congestion control information in a multi-protocol network
Inventor: GULLICKSEN JEFFERY T
IPC: H04L12/70
Filed: 1998-12-17
Abstract: The benefits of Transport Control Protocol (TCP) over Available Bit Rate (ABR) Service of an Asynchronous Transfer Mode (ATM) network is extended to the entire TCP connection by intercepting and modifying TCP congestion control information in accordance with resource information associated with the TCP connection. An algorithm calculates a new advertised window size based on various network resource parameters, such as ABR. The advertised window is adjusted if the newly calculated window size is smaller than the advertised window size. By adjusting the TCP window, the normal extreme fluctuations of the TCP window are avoided.

Abstract: A method is provided for the production of a membrane of gel composite electrolyte having a uniform membrane thickness. The method has the steps of:  mixing a lithium salt, an electrolyte solvent having a boiling point at one atmospheric pressure of not less than 240 ~C and a diluting solvent having a boiling point at one atmospheric pressure of from 40~ to 210 ~C to obtain an electrolyte solution; mixing the electrolyte solution with a gelling agent to obtain a gel composite electrolyte; shaping the gel composite electrolyte into a membrane configuration; and removing the diluting solvent from the gel composite electrolyte. The method is characterized by the use of a diluting solvent. The diluting solvent facilitates the shaping step, thereby producing an electrolyte membrane having a uniform thickness. The gelling agent may be fumed silica.
