Patent CA-2079994-C (CA)
Title: Wiping device of an intaglio printing machine
Inventor: SCHAEDE JOHANNES GEORG
IPC: B41F31/20
Filed: 1992-10-06
Granted: 2004-03-30
Abstract: The wiping device operates with at least one cylinder (3) which receives the ink raised from the printing plates and against which rests a doctor blade (4) which removes the ink from said cylinder (3). In order to clean the doctor blade (4) reliably from ink during the printing operation, there are mounted on the opposite longitudinal edges of said doctor blade (4) wall parts (6) which are U-shaped in the plan view and whose U-limbs (6a) axe directed towards one another. Between said U-limbs (6a), an ink slide (8) is moved constantly back and forth on the doctor blade surface by a drive device, the side parts of said ink slide facing the wall parts being adapted to the design of said wall parts. Installed on the back of the doctor blade (4) on each side is an ink pump whose slot-shaped inlet opening (12) extends between the U-limbs of the relevant wall part (6). The ink slide (8) which is moved back and forth acts like a displacement body and pushes the ink passing onto the doctor blade alternately into the inside space bounded by the one or by the other wall part (6), where it is conveyed away by the ink pump and fed to a container.

Title: Method for the production of storage stable azadirachtin-rich insecticide from seed kernels of the neem tree
Inventor: KLEEBERG HUBERTUS
IPC: A61K36/58
Filed: 1992-03-14
Granted: 2002-10-08
Abstract: Thorough efficiency studies (in relation to the azadirachtin concentration) show, that the biological activity of the active substances obtained by the methods according to the invention corresponds to that of pure azadirachtin.        The proceedures described have the advantage that only very few extraction steps and a very limited number of non-aqueous solvents are necessary and that inspite of this the oil content of the products is very low. From the residues obtained by the described proceedures the neem oil and/or other constituents of the neem kernels may easily be extracted according to known methods.        The described proceedures open the way to the simple and (economically) efficient production of a botanical, environmentally sound insecticide.

Title: Stackable load bearing tray
Inventor: BEAUCHAMP MAURICE
IPC: B65D71/70
Filed: 1994-04-08

Title: Digital data-dependant ac impedance termination of telephone line
Inventor: PARKER GEOFFREY H JR
IPC: H04M3/30
Filed: 1994-06-23
Granted: 2003-12-02
Abstract: The potential impedance mismatch of digital terminal equipment and a line test unit conforming with the Bellcore standard of terminating the line with a 600 - 900 ohm impedance during data reception includes a controllably disabled AC impedance, operable to normally bridge the tip and ring leads of the telephone circuit under test with the required (600-900 ohm) impedance during data reception, under direct control by the craftsman's keypad or software control resident in the test set's microcontroller, to selectively remove the AC matching impedance that would otherwise bridge the line. The AC impedance is comprised of a D.C. blocking capacitor and a resistor coupled in series with a controllable solid state relay which is normally rendered conductive during data reception to bridge the tip and ring leads. By direct manual control from the craftsman's keypad, or software control resident in the test set's microcontroller, the control signal supplied by the microcontroller to the solid state relay may be removed, so as to selectively decouple the AC matching impedance that would otherwise bridge tip and ring leads of the telephone line during data reception.

Title: Method and apparatus for determining platelet function in primary hemostasis
Inventor: VARON DAVID
IPC: G01N33/49
Filed: 1994-07-13
Granted: 2003-12-16
Abstract: A method for determining a platelet function in a primary hemostasis as provided in which a blood sample or a platelet containing fraction thereof is introduced into a vessel having a flat bottom which has an inner surface covered with a substrate capable of inducing platelet adhesion thereto and aggregation such as ECM (extracellular matrix).     Preparation is then rotated inside the vessel, and consequently shear forces develop on the surface which bring to adhesion an aggregation of the blood platelets to the surface. Morphological parameters of blood aggregates are then determined.

Abstract: The invention provides a wheat flour whereby speck formation in a secondarily processed product can be prevented and the deterioration in the color tone due to discoloration can be prevented. To treat tyrosinase of wheat bran which remains in wheat flour in the flour producing process and cause speck formation, a tyrosinase inhibitor is added prior to a roller milling step, preferably in a conditioning step.      Examples of the tyrosinase inhibitor include kojic acid, cysteine, glutathione, ascorbic acid, dithiothreitol, phytic acid, EDTA, isonicotinic acid hydrazide, p-aminosalicylic acid, ferulic acid, thiamine, peptides and combinations thereof. In particular, kojic acid and cysteine are preferable as a tyrosinase inhibitor. The wheat flour thus obtained is usable, for example, in fresh noodles, dried noodles and tenobe somen in a secondarily processed product.

Title: Diaphragm electromyography analysis method and system
Inventor: SINDERBY CHRISTER
IPC: A61M16/20
Filed: 1996-03-21
Granted: 2009-05-19
Abstract: In the method and system for electromyographic analysis of a striated muscle, electromyographic signals produced by the muscle are detected by means of an array of electrodes passing through the center of the muscle depolarizing region. Each electromyographic signal comprises an electromyographic component and a noise component. The position of the center of the muscle depolarizing region is then determined by detecting a reversal of polarity of the electromyographic components of the signals. Finally, two signals of opposite polarities amongst the electromyographic signals are subtracted. The subtraction subtracts the noise components of the two signals from each other but adds the electromyographic components of the two signals together to produce an electromyographic signal of improved signal-to-noise ratio. Advantageously, the array of electrodes is a linear array of electrodes and defines a plurality of pairs of successive electrodes, the center of the muscle depolarizing region is located between the electrodes of a given pair of successive electrodes, and the two signals of opposite polarities detected through the two pairs of successive electrodes adjacent to the given pair on opposite sides thereof are subtracted.
