Patent CA-2236290-C (CA)
Title: Pulsed fluidized bed
Inventor: KUDRA TADEUSZ
IPC: F23C10/18
Filed: 1998-04-28
Granted: 2003-11-04
Abstract: An apparatus and method for processing materials  in a batchwise or continuous fluidised bed, such as a drier, in which the fluidised bed is subdivided into a plurality of smaller areas, to each of which two separately controlled gas flows are provided.   The first lower gas flow is provided to the bed preferably all of the time,  and is  sufficient at  least  to maintain the bed in an expanded state.  The second higher gas flow is  provided to each separate area of the bed in sequence by means of a rotary valve arrangement, and is high enough to induce fluidisation  in  the  bed,  but  not  high  enough  to  induce significant solids loss by entrainment in the offtake gas.  The higher flow sequence can be chosen to provide almost any desired sequence to the separate parts of the bed.  The sequence can be chosen to induce a travelling wave within the bed which can be across or along the bed, and can be skewed relative to the sides of the bed.  In a continuously operated bed, the travelling wave can move either co-currently with,  counter-currently to,  or cross-currently to, the direction of flow of the solids through the bed.   This form of operation, particularly with a skewed travelling wave, improves bed operating efficiency.  Since the rotary valve cannot be closed completely, problems associated with abrasive dust in the gas feed, of valve lubrication, and valve  differential  thermal  expansion  are  all  substantially avoided.

Title: Thermoplastic three-dimensional fiber network
Inventor: KIM DAI W
IPC: D06C23/04
Filed: 1996-12-10
Granted: 2006-08-08
Abstract: Three-dimensional fiber networks which are semi-rigid and dimensionally stable are made from textile fabrics that have projections and optional depressions which are compressible and return to their original shape after being compressed. The fiber networks are made by the thermo-mechanical deformation of textile fabrics that are in turn made from thermoplastic fibers. The fiber networks have particular utility as cushioning and impact absorbing materials.

Inventor: MALLINSON MARTIN
IPC: H03K17/62
Filed: 1997-11-19
Granted: 2001-03-27
Abstract: A current mode analog signal multiplexor includes multiple input multiplexed differential amplifiers (12, 14), a reference amplifier ( 12.0, 14.0) and an output differential current amplifier (18, 20). An input multiplex control signal selects and enables one of the input multiplexed differential amplifiers for buffering and steering the input signal current to one side of the output differential current amplifier. The reference amplifier drives the other side of the output differential current amplifier. The output node of the output differential current amplifier remains at a substantially constant voltage potential while providing an output current which varies in relation to the selected input signal.

Granted: 2006-02-14
Abstract: There is disclosed a method and apparatus for displaying greetings to mobile terminals (30) identifying services associated with location based services. The system identifies a plurality of service zones (Z) in the system, and also transmits predefined services to mobile terminals when located in the service zones. The system transmits from each base station (32) local zone profile information to each of the mobile terminals located in those service zones. Each mobile terminal has stored (95) therein subscriber zone profile information for which that mobile terminal can receive location based services. The mobile terminal also stores (95) an associated greeting for each zone of subscriber zone profile information. The mobile terminal compares (97) transmitted local zone information with the list of stored subscriber zone profile information, and when a match is found, the mobile terminal displays (96) the greeting associated with the subscriber zone profile information. By storing the associated greeting in the mobile terminal, the otherwise signaling of greeting information over the air interface is avoided.
