Patent CA-2161391-A1 (CA)
Title: Stable transformation
Inventor: WALTER CHRISTIAN
IPC: A01H4/00
Filed: 1995-10-25
Abstract: The invention provides a technique for stably inserting foreign genes into conifer cells. The cells to be transformed are in an undifferentiated state such that embryos are likely to regenerate from a single cell. Because of the use of this approach, the probability that the stably transformed plants will be chimaeric is low or non-existent.  Conifer embryogenic tissue may be transformed subjected to extremely toxic levels of selection agent after insertion of foreign genes wherein the foreign genes include genes protective against the selection agent and wherein only stably transformed embryogenic tissue grows on the medium, and non-transformed tissue does not grow. The selected tissue may be used to produce transgenic plants.     In preferred embodiments the cells to be transformed are maintained on a medium having concentrations of inorganic ions within a prescribed range.
Patent CA-2164063-A1 (CA)
Title: Piston valve type carburetor
Inventor: SUGII TOSHIO
IPC: F02D45/00
Filed: 1995-11-29
Abstract: The position located above the upper surface of fuel in a float chamber is communicated with the position where the sectional area of a suction passage varies or the position in the vicinity of the foregoing position via a negative pressure introduction passage.  The intermediate part of the negative pressure passage is opened or closed by a solenoid valve adapted to be controlled by electronic controlling means.  An opening/closing rate of a solenoid valve is determined by inputting informations from a temperature sensor sensing the atmospheric temperature as well as a pressure sensor sensing the atmospheric pressure into the electronic controlling means.  The float chamber is normally communicated with the atmosphere via an atmosphere passage.  As an altitude becomes high more and more, the valve opening time for the negative pressure introduction passage is elongated and the differential pressure between the float chamber and the suction passage is reduced, causing a quantity of ejected fuel to be reduced.  In addition, as the atmospheric temperature becomes high more and more, the valve opening time for the negative pressure introduction passage is elongated and the differential pressure between the float chamber and the suction chamber is reduced, and a quantity of ejected fuel is reduced so that the air fuel ratio is corrected by adjusting a quantity of fuel to be ejected.

Title: Method of incorporating drugs into a polymer component of stents
Inventor: EURY ROBERT P
IPC: A61F2/82
Filed: 1996-03-20
Abstract: The drug-loaded polymeric material containing a therapeutic drug can be applied to a structure of an intravascular stent.  A therapeutically effective amount of a therapeutic drug is incorporated into such a layer of polymeric material, without significantly increasing the thickness of the stent, to avoid interfering with the function of the stent.  The drug-loaded polymer coating of the stent can formed to include pores, can be multi-layered to permit the combination of a plurality of different drug containing materials in a single stent, and can include a rate controlling membrane to allow for controlled retention and delivery of selected drugs within the affected blood vessel upon implantation.  The layer of polymeric material is manufactured by combining the selected polymeric material with a relatively high loading of the therapeutic drug in a thermal process, such as coextrusion of the therapeutic drug with the polymeric material.  The therapeutic drug is dispersed and incorporated into the polymer as small particles, preferably having a maximum cross-sectional dimension of 10 microns.
