Patent CA-2336139-A1 (CA)
Inventor: CAPONETTI GIOVANNI
IPC: A61K9/12
Filed: 1999-06-22
Abstract: Particles incorporating a surfactant and/or a hydrophilic or hydrophobic complex of a positively or negatively charged therapeutic agent and a charged molecule of opposite charge for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the particles are made of a biodegradable material and have a tap density less than 0.4 g/cm3 and a mass mean diameter between 5 µm and 30 µm, which together yield an aerodynamic diameter of the particles of between approximately one and five microns. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of poly(lactic acid) or poly(glycolic acid) or copolymers thereof. Alternatively, the particles may comprise a therapeutic, prophylactic or diagnostic agent and a material selected from the group consisting of surfactant and a molecule having a charge opposite to the charge of the agent and forming a complex thereto. The particles have a tap density less than 0.4 g/cm3 and a mass mean diameter between 5 µm and 30 µm. Exemplary surfactants include phosphoglycerides such as dipalmitoyl phosphatidylcholine (DPPC). The particles are administered to the respiratory tract to permit systemic or local delivery of a wide variety of therapeutic agents. Aggregation of particles before or during administration to the respiratory tract results in particles having an aerodynamic diameter larger than that of the fully dispersed particles. Aerodynamic diameters between three and five microns are advantageous for delivery to the central airways.

Patent CA-2343547-A1 (CA)
Title: Call forwarding on busy or no answer when call waiting is active
Inventor: MALIK DALE W
IPC: H04M3/54
Filed: 1997-06-20
Abstract: A method and an apparatus for handling incoming calls when call waiting is active. If the called party is not on a call when an incoming call occurs and the called party does not answer the incoming call then a message is played to the calling party that the called party did not answer, and the called party is given the opportunity to record a message for the called party. If the called party is on a call when an incoming call occurs and, after the call waiting signal is played to the called party, the called party does not answer the incoming call then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. If the called party is engaged in a first call and a second call when an incoming call occurs then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. Therefore, even when call waiting is active, the calling party is properly advised of the reason that the called party did not answer the incoming call.

Abstract: An improved underwire bra mainly comprises an underwire bra cup, in connection with the properly cut elastic cloth as the lining sewed onto the back side of the bra, and further an obverse elastic cloth with the same contour and configuration fully covers the lining and the bra cup, and forms a whole piece bra with a back piece extended from the lining and the bra cup by coupling the sewing seam at the upper edge such that it completely adopts a woman's bust and provides an underwire bra with seamless look, but it still retains the reliability of lifting and supporting a woman's breast. Such structure simplifies the manufacture, lowers the cost, and enhances the production efficiency.
Patent CA-2352834-A1 (CA)
Inventor: JIN FAHONG
IPC: G02B6/32
Filed: 2001-07-10
Abstract: The present invention relates to an isolated polarization beam sputter or combiner, for joining light from different inputs into one common port, and for dividing a beam of light into orthogonal polarizations. In both modes of operation, the splitter/combiner provides isolation preventing transmission of light in a reverse direction. As a sputter, a beam of light is separated through a birefringent material into sub-beams of orthogonal polarization components, and each sub-beam is passed through a non-reciprocal polarization rotator to rotate the polarization so that a reflected beam, or other counter-transmitted light cannot return on the same path through the birefringent material to the source. As a combiner, two separate beams of light are launched with known orthogonal polarizations into a first birefringent material, passed through a non-reciprocal polarization rotator and then combined as orthogonal polarizations into a single output port. Advantageously, by providing the splitting or combining function in a same isolating device, insertion losses are reduced and the device is smaller and more cost effective. As a further advantage, a polarization beam splitter/combiner is provided in which the optical path length for the two separated orthogonal polarizations traveling through a birefringent crystal is equal, while still permitting the economical use of birefringent crystals with an uncollimated beam of light.

IPC: B01D53/73
Filed: 2001-07-30
Abstract: Sour gas containing hydrogen sulphide has hydrogen sulphide absorbed therefrom in an absorbent in a vessel 4. A hydrogen sulphide rich gas stream is formed by desorbing hydrogen sulphide from the absorbent in a vessel 12. The resulting hydrogen sulphide rich gas stream is partially burned in a furnace 32.  Resulting sulphur dioxide reacts therein with residual hydrogen sulphide to form sulphur vapour which is extracted in a condenser 44. Residual sulphur dioxide and sulphur vapour are reduced to hydrogen sulphide in catalyst stage 54 of a reactor 50.  Water vapour is removed from the resulting reduced gas stream by direct contact with water in a quench tower 60. At least part of the resulting water vapour depleted gas stream is sent to the vessel 4 with the incoming sour gas stream.
