Patent CA-2349370-A1 (CA)
Inventor: MORAN WILLIAM J
IPC: G06F17/30
Filed: 1999-10-04
Abstract: A system creates a plurality of objects, each of which relates to a value point through which digital data passes. The system captures digital data relating to an event, and generates an object tag for an object, which object tag relates the digital data to the event. The digital data and the object tag are then stored in the object. Thereafter, the capturing, generating and storing steps are repeated for each value point through which the digital data passes, and the resulting objects are stored in a memory. These objects may then be retrieved from memory, and used to manage, inventory, monitor, integrate and control the digital data therein and/or corresponding information relating to the event.

Filed: 1999-12-20
Abstract: Image information necessary to display a three-dimensional image of an objec t in a space is acquired with a simple structure, and a three-dimensional dynamic image in a true sense is displayed with a simple structure. Part of light from an object (10) falls on a polarizer (11). The polarizer (11) pass es the component of the incident light polarized at a predetermined angle to th e surface of the polarizer (11) and allows the component to emerge from the polarizer (11) as parallel light perpendicular to the surface of the polariz er (11). The parallel light passes through a condenser lens (12), a pinhole member (13), and a condenser lens (14) and falls on a CCD (15). The angle of  incident light selected by the polarizer (11) can be changed with time. Therefore, the image information outputted from the CCD (15) is a set of ite ms of two-dimensional image information including the direction of imaging changing with time and is necessary to display a three-dimensional image of an object in a space.

Title: High-strength low-alloy steel anodes for aluminium electrowinning cells
Inventor: DURUZ JEAN-JACQUES
IPC: C25C3/12
Filed: 2000-01-10
Abstract: An anode of a cell for the electrowinning of aluminium comprises a low-carbon high-strength low-alloy (HSLA) steel body or layer whose surface is oxidised to form a coherent and adherent outer iron oxide-based layer the surface of which is electrochemically active for the evolution of oxygen. The iron oxide-based layer has a low solubility in the molten electrolyte. During use, the thickness of the iron oxide-based layer is such as to reduce or prevent diffusion of oxygen from the electrochemically active surface into the steel body or layer. During cell operation, the anode may be maintained dimensionally stable by saturating the electrolyte with anode constituents.
