Patent CA-2243292-A1 (CA)
Inventor: BOMANS MURIEL
IPC: B64D45/00
Filed: 1997-01-14
Abstract: The invention relates to air navigation aid devices and methods used in flight management systems onboard of aerodynes. In order to facilitate the task of the pilot, the onboard computer (FMS) dialogues with the pilot through a multipurpose control display unit (MCDU). Said unit displays a list of tasks to be executed in the form of a succession of selectable and activatable main zones (40). Each zone corresponds to a task, executed through the unit, and when the task has been executed (validation key actuated by the pilot), the list of tasks is redisplayed with a specific mark in an auxiliary zone (50) corresponding to the executed task. The auxiliary zone is arranged next to the main zone wherein appears the task to be executed. The co-pilot, if any, receives the same mark. If it is the co-pilot who executes the procedure, the mark appears in another auxiliary zone (60) situated on the other side of the main zone. At any time of the procedure, the pilot and the co-pilot see both of them at a glance which tasks have been executed, who has executed each of the tasks, and which tasks remain to be executed.

Title: Method of and apparatus for applying coating liquid to base plate by die coater and apparatus for supplying coating liquid to die coater
Inventor: NISHIO TSUTOMU
IPC: B05C11/02
Filed: 1996-09-06
Abstract: A base plate coating method using a die coater. A base plate is placed on a support surface having a flatness of not more than 2 µm and a plurality of suction holes. The base plate is then sucked onto the support surface via the suction holes and thereby brought into close contact therewith. Consequently, the deformation (for example, torsion and flexure) of the base plate is eliminated. A coating liquid discharged vertically from a die coater is then applied to the base plate as the die coater is moved relatively to the base plate. As a result, a film of coating having a predetermined thickness is formed on the base plate.

Title: An improved technique for jointly performing bit synchronization and error detection in a tdm/tdma system
Inventor: ZIEGLER ROBERT A
IPC: H04L1/00
Filed: 1996-04-18
Abstract: An improved technique for simultaneously performing bit synchronization (100) and error detection (150) of received digital data bursts in a time division multiplexed/time division multiple access (TDM/TDMA) system, such as that used in conjunction with low power portable digital telephony. With the improved technique both bit synchronization (100) and error detection (150) are performed simultaneously to thereby reduce latency in the transceiver. Since round-trip delay is reduced, echo suppression techniques may not be needed.

Title: Dual string backup tong
Inventor: VEVERICA MARK
IPC: E21B19/16
Filed: 1997-02-28
Abstract: A backup tong (1) having an inner throat (19) sized to accommodate a second pipe string while a first pipe string is held within the jaws (12, 13) of the tong is disclosed. The inventive backup tong facilitates operations on dual pipe strings by allowing the tong to grip not only the closer of two pipe strings, but also the farther of the pipe strings by allowing the nearer pipe string to reside in an inner throat of the backup tong, between the gripping members (16, 17) of the tong and the body of the backup tong, while the farther pipe string is held between the gripping members. The inventive backup tong thereby allows the operator to grip either of the pipe strings from a single side, eliminating the side-to-side movement (and corresponding time and risk of harm) which is required when using prior art backup tongs.

Title: Bulk handling apparatus
Inventor: MCLAUGHLIN EDWARD
IPC: B65G57/24
Filed: 1997-05-15
Abstract: A method and apparatus for stacking newspapers is disclosed which obviates the need to fasten individual stacks. Once ejected from a stacking device, stacks of newspapers pass through an assembly station where they are arranged into groups of three, called slugs (7), and compressed. The slug then enters a collector where a layer consisting of four slugs is positioned on a sliding table (43). This positioning requires lateral movement of slugs. Lateral support is provided throughout this movement to prevent the stacks from toppling over. Once a full layer has been accumulated, the sliding table is retracted, and the layer of newspapers falls on to a floating table below.  This floating table (23), which serves as the bottom floor of the container (25) in which it is housed, is automatically lowered by discrete amounts as layers are received. Extendible cylinders located below the collector vertically move the floating table. Since the four walls of the container provide the requisite lateral support, layers of unfastened stacks are able to be securely deposited on the floating table. Once the full container is removed from the collector, a fork lift raises the floating table by inserting its prongs into a gap created between the floating table and the open bottom of the container. In another aspect of the invention, bottom copy damage associated with lateral movement of newspapers is reduced by positioning the stacks so that the nose of the bottom group of newspapers in each stack points in the ultimate direction of lateral movement.

Title: A method of processing signals of a satellite positioning system
Inventor: COOPER JOHN
IPC: G01S1/00
Filed: 1998-12-08
Abstract: The invention relates to a method of treating the L1 and L2 signals of a positioning system in which each of said L1 and L2 signals presents a single frequency carrier modulated by a known pseudo-random code P, itself modulated by an unknown code W, in which: a) each of the signals L1 and L2 is correlated in a respective system with a locally-generated replica of the P code; b) the first and second correlation signals obtained over a period equal to an estimated period (T1) for a bit of the W code are integrated to obtain respective first and second W code bit signals; and c) cross-correlated is then performed thereon.      The invention is characterized in that, between b) and c), a test is performed firstly to see whether the first and/or second W code bit signal is greater than a first positive threshold value or less than a first negative threshold value, and for the purposes of said cross-correlation, only those first and/or second W code bit signals are retained for which the corresponding test is satisfied.

Some of the layers (42) have sub-grains (46) extending perpendicularly to the surface of the metallic article (30) to provide erosion resistance.

Title: Numerical analyzing method, element analyzing blocks, and processing apparatus for numerical analysis
Inventor: KAWAI TADAHIKO
IPC: G06F17/13
Filed: 1999-06-17
Abstract: The present invention provides a numerical analyzing method, by which equations of every element of a phenomenon represented by partial differential equations can be solved independently from each other by the direct method or the iteration method without using any collocation method such as the domain decomposition method, the finite difference method or the finite element method.     A defined domain is decomposed in mesh (S1); state vectors in each element of the mesh are approximated by polynomials of finite number of terms with respect to coordinate variables (S2); and then conditions between different undetermined coefficients satisfying given govering equations are obtained. Next equations representing relationships between the undetermined coefficients of each element (element state equations) required for satisfying continuity conditions of state vectors on peripheral boundaries of every element are obtained by the least squares method to obtain a square matrix equation (S4). Further an element matrix at that time is reduced by decomposition (S5), taking the boundary conditions given on the periphery into account, and square matrix equations thus obtained are solved either by the iteration method as it is, in case where they are separated from each other, or by the direct method as a whole (S6). State vectors at arbitrary points are calculated by using calculation results obtained in this way.
