Patent CA-2148083-A1 (CA)
Title: Method of and apparatus for extrusion molding
Inventor: ANDO YUKIMASA
IPC: B29C48/325
Filed: 1993-12-27
Abstract: According to the invention, a preliminary extrusion is performed to find an optimum back pressure which can provide a predetermined sectional size for respective portions of a movement pattern DA of a movable die, which pattern is determined by a shape of a product. It is assumed that the movable die is positioned at a position DA1 corresponding to a side portion of a product and a value of a back pressure BP, at which a molded material, is made an optimum back pressure BPO. An optimum back pressure for an upper portion of a product is determined in a like manner to decide a pattern of the optimum back pressure BPO. Taking into account time lag, a timing, at which an initial set pattern R1 for rotations of the screw is changed, is set a period of time T11 to T14 ahead of a timing, at which the pattern DA is changed. In a regular extrusion, an actual take-up speed is measured, and when the measured speed is different from that at the time of the preliminary extrusion, the movement pattern DA of the movable die is corrected. When the measured back pressure BP is deviated from the pattern of the optimum back pressure BPO after several cycles of extrusion molding have been executed, the pattern R1 for rotations of the screw is corrected.

Title: Electrosurgical hemostatic device with adaptive electrodes
Inventor: SCHULZE DALE R
IPC: A61B17/115
Filed: 1996-04-10
Abstract: An improved electrosurgical device having an end effector capable of receiving electrosurgical energy therein. The end effector comprises first and second opposing interfacing surfaces. The interfacing surfaces are capable of engaging tissue therebetween. There is provided a first electrode of a first electrical potential and a second electrode being insulated from the first electrode and having a second electrical potential that is different from the first electrical potential. The first and second electrodes are arranged to receive the electrosurgical energy therein. The opposing interfacing surfaces are electrically insulated and the first electrode is located on the first interfacing surface and the second electrode is located on one of the first and second interfacing surfaces. The improvement resides in that the first electrode is a spring electrode that is flexible so that it is moveable towards and away from the first electrode and is biased towards the second electrode. The result is that this enables the distance between the electrodes to be continuously adaptable to different tissue impedances due to different thicknesses and compressibilities of the engaged tissue. In another aspect the invention provides an electrosurgical kit comprising the electrosurgical device and at least two interchangeable cartridges, which cartridges are insertable into the end effector to form at least a portion of a first interfacing surface.

Abstract: One aspect of the invention is to provide novel genetic constructions for the expression of inhibitory RNA in the cytoplasm of eukaryotic cells. The inhibitory RNA may be an anti-sense RNA or a co-suppressor RNA. The genetic constructions of the invention are capable of replicating in the cytoplasm of a eukaryotic cell and comprise a promoter region in functional combination with an encoding polynucleotide. The genetic constructions may be designed so as to replicate in the cytoplasm of plant cells, yeast cells, and mammalian cells. When the eukaryotic cell of interest is a plant cell, the genetic construction is preferably derived from a plant RNA virus. Plant RNA virus derived genetic constructions may employ a plant virus subgenomic promoter, including subgenomic promoters from tobamoviruses in functional combination with the RNA encoding region. Another aspect of the invention is to provide cells comprising the genetic constructions of the invention and organism comprising a plurality of such cells. Another aspect of the invention is to provide methods of reducing the expression of a gene of interest in eukaryotic cells, i.e., methods of producing eukaryotic cells exhibiting reduced levels of expression of a gene of interest. The methods of the invention comprise the step of transfecting a cell with a genetic construction of the invention in which the RNA encoding region is specific for the gene of interest. Another aspect of the invention is to provide plant cells that produce elevated levels of the carotenoid phytoene. The elevated levels of phytoene are achieved by inhibiting the expression at the enzyme phytoene desaturase using the vectors of the invention.
