Patent CA-2313157-A1 (CA)
Inventor: RENWICK PHILIP
IPC: B22D46/00
Filed: 2000-06-29
Abstract: A method of optimizing cycle time and/or casting quality in the making of a cast metal product which has been defined by a CAD product model. The method involves the steps of (a) providing a computer casting model using objective functions that simulate the filling and solidification of the CAD product model within dies, the casting model being subdivided into contiguous regions with each region having terms in at least one of the objective functions for thermal conductivity, heat capacity and cooling time period, (b) populating the objective function terms with experimental data to calibrate the casting model, derive matching heat transfer coefficients for each region, and simulate filling and solidification of the product within the dies, and (c) constraining the objective functions to ensure directional solidification along the series of contiguous sections while optimizing thermal conductivity and heat capacity and iteratively evaluating the constrained objective functions to indicate at least certain regions of the casting model whereby chills and cooling channels may be added, or insulation added to effect improved cycle time and/or casting quality.

Patent CA-2314957-A1 (CA)
Inventor: SENDA TAKAYUKI
IPC: G02B6/132
Filed: 2000-08-03
Abstract: Proposed is a method for fabricating a planar optical waveguide device having a plurality of core segments (4, 14, 24, 34, 44) formed between a lower clad layer (2, 3, 12, 13, 23, 33, 43) and an upper clad layer (5, 15, 25, 35, 45), in which a hot isostatic pressing process (HIP) is carried out during the fabrication process. The lower clad layer may consist of a substrate (2, 12) or a buffer layer (3, 13, 23, 33, 43) formed on a substrate. Each layer may be formed either by a low-temperature film-forming process such as CVD or by the flame hydrolysis pressing process. The HIP process is also effective in eliminating voids when the core is formed in a recess of the lower clad layer. According to the tests conducted by the inventors, it was found that the HIP process can be conducted without requiring any protective layer or a gas barrier through proper selection of the condition for the HIP process, as opposed to the common belief that a protective layer or a gas barrier is essential for the HIP process.

Title: Air-conditioning system for airplane cabin
Inventor: SAUTERLEUTE ALFRED
IPC: F25B9/00
Filed: 2000-11-29
Abstract: An air-conditioning system for airplanes in which a portion of the fresh airflow is tapped at high pressure from a power unit and another portion is sucked in from the ambient air. The energy potential of the tapped airflow is utilized to compress the ambient air. The compressed ambient air and the tapped air are mixed before the pressure of the combined airflow is reduced by passage through one or more turbine stages. Water is separated from the mixed airflow between the mixing point and the first turbine stage. In order to cool the tapped airflow to a temperature at which water can be separated, the tapped airflow is passed in a heat exchaning manner past the entire cooler mixed airflow, preferably in two steps, one before pressure reduction and one after the pressure reduction of the mixed airflow in the first turbine stage. The ambient air can be compressed in two steps, by using two compressor wheels and two turbine wheels mounted together on a shaft.

Abstract: A wireless handset does not perform a re-registration operation when its serving base station is at capacity, and a wireless controller controlling a wireless switching system is allowed to send incoming calls for the wireless handset to the base station even if the base station is at capacity. The base station signals a new call to the wireless even if the base station is-at its active call capacity. The wireless handset is responsive to the incoming call to perform a base station re-direct operation to a new base station that has idle call capacity, and the call setup is completed to the wireless handset via the new base station. The base station re-direct operation is a new wireless operation. The base station re-direct operation is controlled by the system wireless controller in a second embodiment.
