Patent CA-2162091-A1 (CA)
Inventor: SASAKI CHIHARU
IPC: H04B1/12
Filed: 1995-11-03
Abstract: A distortion compensating circuit comprises a frequency control section, a filtering section and an eliminating section.  Major frequencies are detected from an input signal including major signals having the major frequencies by a major frequency detector performing spectrum analysis of the input signal.  Receiving the major frequencies, the frequency control section calculates distortion frequencies from the major frequencies based on predetermined formulae representing the nonlinear distortion.  The predetermined formulae are stored in advance.          The frequency control section generates frequency control signals indicating the distortion frequencies.  After the input signal is divided into a first signal and a second signal, the filtering section extracts frequency components having the distortion frequencies from the first signal in response to the frequency control signals.  The frequency components are eliminated from the second signal by combining the phase-reversed frequency component with the second signal by the eliminating section.
Patent CA-2162387-A1 (CA)
Inventor: HYPPANEN TIMO
IPC: F23C10/24
Filed: 1994-05-16
Abstract: Particles in a fluidized bed reactor (e.g. a circulating fluidized bed reactor) are discharged from the reactor chamber (10) and then cooled (heat is recovered from them) in a processing chamber (16). This is accomplished in a particularly advantageous way by discharging the particles from the reactor chamber at a first level (e.g. through a non-mechanical seal or a classifying wall) into a lifting chamber (14). Upwardly flowing gas in the lifting chamber entrains the particles and lifts them into the processing chamber. After processing, the particles in the processing chamber are returned to the reactor chamber at level higher than the first level, at which point the pressure in the processing chamber is higher than the pressure in the reactor chamber. The particles may be classified in the lifting chamber by utilizing fluidizing gas to transport solid particles smaller than a predetermined size to the processing chamber while discharging larger particles from the bottom (38) of the lifting chamber.

Title: Lacing system for skating boot
Inventor: REYNOLDS ALEXANDER P
IPC: A43B5/16
Filed: 1996-07-10
Abstract: A lacing system for skating boot comprising a mix of fixed and floating eyelets provides flexibility without requiring a break-in period of wear. The past vertical, fixed eyelets accommodates a knees-flexed position of a skater, and the independently movable, floating eyelets provides a comfortable but close fit of the boot. Notches in the area of the floating eyelets further reduces buckling or creasing of the material at about the instep region. An optional lacing ring below the notch aids in dispersing tension at the flex region and also aids is preventing creasing of the material. Thus, increased flexibility and comfort is provided without the usual break-in period and without loss of foot support or durability.

Patent CA-2196802-A1 (CA)
Inventor: WISSLER JOSEF
IPC: A61K38/00
Filed: 1996-07-17
Abstract: Bioactive copper-, zinc- or calcium-containing ribonucleopolypeptides (RNP) are disclosed. They are non-mitogenic morphogenetic agents for blood vessels and have a defined primary structure for intercellular communication containing genetic information. Zn/Ca/Cu-RNP may enzymatically hydrolyse nucleic acids in a controlled manner (controlled nuclease activity) and their bioactivity may be mutually modulated and controlled by means of their Zn/Ca/Cu metal ion content, that acts as a "molecular switch". These compounds selectively stimulate directional growth or morphogenesis of blood vessels in vivo and in vitro and cause neovascularisation of tissues. Also disclosed are a process for preparing and extracting RNP, their use and medicaments.

Patent CA-2201504-A1 (CA)
Title: Method and devices for producing somatosensory stimulation using temperature
Inventor: SARINGER JOHN H
IPC: A61F7/02
Filed: 1995-09-27
Abstract: The present invention provides a method of abatement of pain using somatosensory stimulation and devices for implementing the method. The method involves application of spatially modulated temperature diffe rences to the skin in the vicinity of pain. The application of a spatial temperature difference produces a large sensory stimulus along neur al pathways the same as or adjacent to those transmitting the signals giving rise to the sensation of pain. This acts to cause the brain t o block sensation from the affected area thereby alleviating the pain and the brain has no built in method of adapting or habituating to this typ e of sensory input. The temperature differential applied is up to 40-45 .degree.C with the high temperature maintained at or below 45.degree.C and the low temperature at or above 0.degree.C to prevent tissue damage. Several devices are disclosed for implementing the method with one being a handheld device using a thermoelectric unit to both heat and cool adjacent parts of a surface which is in contact with the skin. Another larg er device uses a thermoelectric unit disposed between two water pumps each of which pumps water to different sections of a flexible water bag which is strapped to the affected area of the user. Water pumped over one side of the thermoelectric unit is heated and water pumped over the other side is cooled.

Title: Isolated porcine pancreatic cells for use in treatment of diseases characterized by insufficient insulin activity
Inventor: DINSMORE JONATHAN
IPC: A61K35/39
Filed: 1995-10-18
Abstract: Isolated porcine pancreatic cells, isolated populations of such cells and methods for isolating and using the cells to treat subjects with diseases characterized by insufficient insulin activity are described. The porcine pancreatic cells are preferably non-insulin-secreting porcine pancreatic cell having the ability to differentiate into aninsulin-secreting cell upon introduction into a xenogeneic subject, such as a human subject. Such cells include embryonic porcine pancreatic cells obtained from embryonic pigs between about day 31 and day 35 of gestation. The porcine pancreatic cells can be modified to be suitable for transplantation into a xenogeneic subject, for example, by altering an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in the subject (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof). The isolated porcine pancreatic cells of the invention can be used to treat diseases characterized by insufficient insulin activity, e.g., Type I and Type II diabetes, by administering the cells to a subject having such a disease.

Title: Method for making honeycomb core composite articles
Inventor: OSIECKI LARRY J
IPC: B32B3/12
Filed: 1995-01-27
Abstract: A method for making a honeycomb core composite article includes forming a honeycomb core (24) and a precured composite skin (20) having a core edge (32) and a restraint edge (30), respectively. The precured composite skin (20) is placed in combination with a rigid mold member having a mold surface (12s) and the honeycomb core (24) is mated with the precured composite skin (20) to form a mated subassembly (36). An uncured composite skin (22) is laid over the mated subassembly (36) such that a peripheral portion (44) of the uncured composite skin (22) extends beyond the restraint edge (30) by a distance X and such that the peripheral portion (44) is in superposed abutting engagement with the mold surface (12s). The honeycomb core (24), the precured composite skin (20) and the uncured composite skin (22) define a composite lay-up (10) over which a vacuum bag (14) is disposed. The resultant mold cavity (60) is evacuated to urge the vacuum bag (14) against the uncured composite skin (22) thereby effecting engagement of the peripheral portion (44) with the restraint edge (30) and the mold surface (12s). The composite lay-up (10) is then cured to form the completed honeycomb core composite article. The method produces a honeycomb core composite article wherein the honeycomb core (24) thereof is accurately located and substantially distortion-free.
