Title: Method for recovering nickel from high magnesium-containing ni-fe-mg lateritic ore
Inventor: LIU HOUYUAN
IPC: C22B26/22
Filed: 1996-05-08
Abstract: A method is provided for recovering nickel from high magnesium-containing lateritic ores which also contain iron. The ores which are referred to as saprolitic ores are subjected to leaching (2) with a mineral acid from the group consisting of HC1, H2SO4 and HNO3, HC1 being preferred. Following leaching with HC1, for example, the pregnant solution obtained is separated from undissolved solids and the nickel preferably recovered by contacting the solution with a resin (4) selective to nickel absorption. The raffinate remaining which contains iron and magnesium chlorides may be subjected to pyro-hydrolysis (10A) to produce their respective oxides and free HC1 for recycle into the leaching system. The nickel is extracted from the resin using a stripping solution of the acid, and the nickel thereafter extracted from the nickel-loaded stripping solution.

Title: Interleaving and de-interleaving method for digital data, interleaving and de-interleaving devices, and communication system
Inventor: PEETERS MIGUEL
IPC: H03M13/27
Filed: 1998-01-27
Abstract: A triangular interleaver (INTERLEAVER) contains a triangular shaped matrix (MAT)of memory cells, each row of which constitutes a first-in-first-out queue. To increase or decrease the interleave depth of the interleaver (INTERLEAVER), the number of interleaved data bytes read from each row of the matrix (MAT) is positively or negatively linearly related to the ordinate number (0, 1, 2, 3, 4) of this row. In this way, impulse noise immunity of transmission of the outgoing interleaved data stream (OID) over a transmission line (TL) is kept substantially independent from transmit rate changes.

Patent CA-2238450-A1 (CA)
Title: Vertically adjustable wheel assembly
Inventor: HEIMS DOUGLAS A
IPC: B60B33/06
Filed: 1998-05-22
Abstract: A vertically adjustable wheel assembly for movably supporting an appliance cabinet or the like upon a supporting surface includes a housing, a supporting bracket, a wheel unit, an adjusting rod, an adjusting screw and various elongated mounting members. The wheel unit is defined by a pair of spaced rollers that are interconnected by a reduced diametric portion. The wheel unit is rotatably attached to the support bracket by an axle member, while the adjusting rod is also mounted for rotary movement by the support bracket.      The support bracket is pivotally mounted to the housing, with both the wheel unit and the adjusting rod being permitted to rotate relative thereto. The adjusting screw extends through a frontal portion of the housing and it is threadably connected to the adjusting rod such that rotation of the screw causes pivoting of the support bracket relative to the housing and movement of the wheel assembly between fully extended and fully retracted positions. With the rollers of the wheel unit being laterally spaced, the adjusting screw is permitted to extend between the rollers when the adjustable wheel assembly assumes the retracted position. The arrangement represents an extremely compact vertically adjustable wheel assembly that can be advantageously preassembled and attached to a refrigerator cabinet or the like as a unit.

Title: Wireless fleet communications system for providing separable communications services
Inventor: DOYLE THOMAS F
IPC: G06Q10/08
Filed: 1998-07-23
Abstract: A method and apparatus for providing personal and business mobile wireless communications service is described. A message (40) is received having a message type (44). Message separability and cost allocation is performed based on the message type. The message (40) is processed when the message (40) is a fleet message, and the message (40) is forwarded to a message management center (20a) when the message is a personal message. Once the message is forwarded, it is deleted. In one embodiment of the invention, the messages are transmitted via a wireless satellite link between a mobile communications terminal (10) and a network management system (16). A fleet computer (18a) receives the messages from the network management system (16) and, after determining whether they are personal or fleet messages, processes them accordingly.

Title: Web-based access to teaching files in a filmless radiology environment
Inventor: HENRI CHRISTOPHER J
IPC: G09B23/28
Filed: 1998-08-04
Abstract: This paper describes the design and implementation of a low-coat PACS  comforming to the DICOM 3.0 standard The goal was to provide an efficient image archival and management solution on a heterogeneous hospital network as a basis for filmless radiology. The system follows a distributed, client/server model and was implemented at a fraction of the cost of a commercial PACS. It provides reliable archiving on recordable CD and allows access to digital images throughout the hospital and on the Internet. Dedicated servers have been designed for short-term storage, CD-based archival data retrieval and remote data access or teleradiology. The short-term storage devices provide DICOM storage and query/retrieve services to scanners and workstations and approximately twelve weeks of 'on-line' image data. The CD-based archival and data retrieval processes are fully automated with the exception of CD loading and unloading. The system employs lossless compression on both short- and long-term storage devices. All servers communicate via the DICOM protocol is conjunction with both local and 'master' SQL patient databases. Records are transferred from the local to the master database independently, ensuring that storage deviced will still function if the master database server cannot be reached. The system features rules-based work-flow management and WWW servers to provide multi-platform remote data access. The WWW server system is distributed on the storage, retrieval and teleradiology servers allowing viewing of locally stored image data directly in a WWW browser without the need for data transfer to a central WVW server. An independent system monitors disk usage, processes, network and CPU load on each server and reports errors to the image management team via email. The PACS was implemented using a combination of off-the-shelf hardware freely available software and applications developed in-house. The system has enabled filmless operation is CT. MR and ultrasound within the radiology department and throughout the hospital. The use of WWW technology has enabled the development of an intuitive web-based teleradiology and image management solution that provides complete access to image data.     Keywords: PACS.

Title: Array feed for axially symmetric and offset reflectors
Inventor: WIGHT JIM
IPC: H01Q21/22
Filed: 1997-03-19
Abstract: In the past, parabolic offset reflector antennas were fed a signal through a corrugated horn in order to optimise field distribution and polarisation at the reflector. It has been found that cost savings and other advantages are realised by using an array of radiating patches. The geometrical placement of the radiating patches and the power distribution to each patch is arranged such that radiated energy from the patches sums at the reflector surface to produce the predetermined field distribution and polarisation.

Patent CA-2251855-A1 (CA)
Inventor: LIIBBE ALLEN L
IPC: B01D46/24
Filed: 1998-10-26
Abstract: A replaceable air filter for filtering inlet air to an engine has a heavy-duty housing which protects the filter element from heat and damage due to improper handling. The durable housing further provides additional surfaces for mounting the air filter to a combustion engine. The filter element inside the housing is permanently sealed to the housing, thereby reducing the risk of unfiltered air from bypassing the filter element to enter the air intake tube. Because the filter element is permanently attached to the housing, the entire air filter must be replaced during routine maintenance, thereby reducing the risk of loose dirt from spent filters being drawn into the engine. A snout member is injection molded to have an air outlet which may be sized for connection with either a flexible or rigid air intake tube.
