Patent CA-2200124-A1 (CA)
Inventor: BAILLARGEON JAMES N
IPC: H01L33/36
Filed: 1997-03-17
Abstract: Heteroepitaxial growth of phosphorus-containing III/V semiconductor material (e.g., InGaAsP) on a non-planar surface (11) of a different phosphorus-containing III/V semiconductor material (e.g., InP) is facilitated by heating the non-planar surface in a substantially evacuated chamber to a mass-transport temperature, and exposing the surface to a flux of at least phosphorus form a solid phosphorus source. This mass-transport step is followed by in situ growth of the desired semiconductor material, with at least an initial portion of the growth being done at a first growth temperature that is not greater than the mass transport temperature. Growth typically is completed at a second growth temperature higher than the first growth temperature. A significant aspect of the method is provision of the required fluxes (e.g., phosphorus, arsenic, indium, gallium) from solid sources, resulting in hydrogen-free mass transport and growth, which can be carried out at lower temperatures than is customary in the prior art. An exemplary and preferred application of the method is in grating formation and overgrowth in InP-based DFB lasers.

Title: Extracts of shark cartilage, process of production and uses thereof
Inventor: DUPONT ERIC
IPC: A61K9/10
Filed: 1995-10-30
Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, direct anti-tumor proliferating, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being centrifuged and further fractionated to obtain a total extract having molecules of a molecular weight comprised between 0 to 500 KDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis. This extract has no offensive effect on normal body functions. Therefore, this shark cartilage extract has a very promising therapeutic value. The process for the obtention of cartilage extracts is simple and efficient. The unexpectedly valuable products obtained by this process are therefore an indication of a new and non-obvious process.

Title: Vascular tissue sealing pressure control and method
Inventor: KENNEDY JENIFER S
IPC: A61B17/12
Filed: 1996-08-12
Abstract: A clamping force mechanism (10) and its method of use with electrosurgery allow a user to seal and/or joint patient's particular vascular tissue; the mechanism is elongate with user and patient ends (14). An actuator (15) is at the user end (13) and the effectors are at the patient end (14). Each effector has a face of an area to contact the particular vascular tissue. A lost motion connection (18) transfers user actuation to the effectors to hold a predetermined clamping force during electrosurgical tissue sealing. A yielding member (19) in the loss motion connection clamps the particular tissue between the faces with a predetermined force. The yielding member (19) is a spring (20), slip clutch (36) or hydraulic coupling possibly near the actuator (15).  An active electrode is carried on one end effector and a return electrode (24) contacts the tissue so an electrosurgical energy supply (25) connected thereacross delivers energy therebetween. A feedback circuit (27) responds to parameters of energy delivered to tissue. A temperature sensor (28) on one face and an impedance monitor (29) respond to energy delivered. A control (30) applies energy to held tissue to seal and/or join it. The method transfers user actuation of the effectors with the lost motion connection (18), maintains clamping force while sealing and applying electrosurgical energy to seal and/or join held tissue. Energy is applied to a temperature or an impedance. The method shifts the yielding member (19) so the opposing faces (17) clamp the particular tissue therebetween with the force from the spring (20), via a transfer rod or by the hydraulic coupling or the slip clutch (36) for a range of pressure.

Title: Real time colour calibration and correction (rt3)
Inventor: DESBOROUGH MARK
IPC: G06K15/02
Filed: 1998-04-16
Abstract: This invention is directed to a method and system for real time colour calibration and correction during a colour printing run that is by an RTC  computer. This method involves creating a computer generated output file that is loaded onto the RTC computer, modifying the file as needed to remove any extraneous data, scanning the file in order to preset colour keys and set the RTC scanning controller with initial colour values, preparing a high resolution colour proof, determining suitable areas within the image region of the proof for use as calibration points that are monitored during the printing run, selecting a printed output during the printing run, scanning the pre-selected suitable areas of this printed output, storing the information within the RTC scanning controller and sending the information to the RTC computer for comparison with the initial colour values, and adjusting the required colour keys to correct for any differences noted in the printed output. The use of the RTC  system ensures real time colour correction during a printing run with minimum down time and colour consistency over an entire print run. This is especially useful for large printing jobs where colour consistency is an issue and difficult to maintain.
Patent CA-2235527-A1 (CA)
Inventor: BROWN BRUCE
IPC: H04L12/70
Filed: 1998-04-22
Abstract: A method of determining whether a requested parameter reconfiguration of a connected call in a switched digital communication network complies with system constraints is described. Bandwidth related parameters, in particular, are subject to reconfiguration after a call is provisioned in order to optimize utilization of network resources. The implementation of a bandwidth reconfiguration involves an assessment of bandwidth utilization by the logical or physical links routing the connected call so that the reconfigured bandwidth does not negatively impact on the connected call.      Once the reconfigured parameter is determined to be acceptable the reconfiguration data is propagated to the relevant network elements.

Title: Collagen and collagen-derived products free of any infectious agent, implants comprising the same and methods of making thereof
Inventor: DROUIN REGEN
IPC: C07K1/14
Filed: 1997-01-29
Abstract: The use of collagen as a biomedical implant raises safety issues towards viruses and prions. The physicochemical changes and the in vitro and in vivo biocompatibility of collagen treated with heat, and by formic acid (FA), trifluoroacetic acid (TFA), tetrafluoroethanol (TFE) and hexafluoroisopropanol (HFIP) were investigated. FA and TFA resulted in extensive depurination of nucleic acids while HFIP and TFE did so to a lesser degree. The molecules of FA, and most importantly of TFA, remained within collagen. Although these two acids induced modification in the secondary structure of collagen, resistance to collagenase was not affected and, in vitro, cell growth was not impaired. Severe dehydrothermal treatment, for example 110 ~C for 1-3 days under high vacuum, also succeeded in removing completely nucleic acids. Since this treatment also leads to slight cross-linking, it could be advantageously used to eliminate prion and to stabilize gelatin products. Finally, prolonged treatment with TFA provides a transparent collagen, which transparency is further enhanced by adding glycosaminoglycans or proteoglycans, particularly hyaluronic acid. All the above treatments could offer a safe and biocompatible collagen-derived material for diverse biomedical uses, by providing a virus or prion-free product.
