Abstract: Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by using energy stored in a capacitor at a breakdown for creating an ignition arc at the electrodes of a spark plug, designed to preclude interference of contaminants with conduction of an ignition arc across an established current path between the electrodes of the spark plug. An air gap and a sparkplug are connected in series, wherein the sparkplug produces an ignition arc in a fuel to be ignited. A first high voltage power supply develops a first direct current voltage across the capacitor, which is supplied as a voltage across the air gap and the spark plug. A second high voltage power supply supplies a second pulsed voltage across the air gap and the spark plug, wherein thesecond pulsed voltage is substantially higher than the first direct current voltage, and the second pulsedvoltage jumps the gap of the air gap and thus initiates an ignition arc, and the first direct current voltage is current limiting thereby allowing the capacitor voltage to approach zero, and thus allowing the air gap to cease conducting, thereby allowing the cycle to repeat itself. A diode is positioned between the second pulsed voltage and the capacitor of the first high voltage power supply to isolate the capacitor from the second pulsed voltage.

Title: Engine valve operating system
Inventor: NAKAMURA KATSUNORI
IPC: F01L1/18
Filed: 2004-05-28
Granted: 2009-12-29
Abstract: In an engine in which a lift amount of a valve can be changed continuously, an engine valve operating system including a valve lift-changing mechanism is capable of increasing and decreasing the lift amount of the valve without changing an opening angle for the valve and capable of decreasing a tappet clearance in accordance with a decrease in lift amount of the valve. Thus, it is possible to prevent the ratio of the tappet clearance to the lift amount at a low valve lift from being increased to minimize the influence of the dispersion of the tappet clearance and to reduce the seating speed of the valve at the low valve lift to prevent the generation of a noise. It is also possible to prevent a reduction in performance of the engine at a high valve lift due to the dispersion of the tappet clearance and to decrease the seating noise of the valve at the low valve lift.

Title: Stabilised solid drug dispersions in an organic carrier and a process for preparing the same
Inventor: COLOMBO ITALO
IPC: A61K9/16
Filed: 2003-12-22
Granted: 2012-10-30
Abstract: New solid drug dispersions are described in which the drug is present in amorphous form and massively dispersed (in bulk) inside the particles of an organic carrier selected from cross-linked polymers and/or a complexing agents. These dispersions are obtainable by mixing together the drug and the carrier and applying an oscillating electromagnetic field to the mixture, to a frequency belonging to the microwave region; the microwaves are applied according to a specific heating cycle wherein the drug-carrier mixture is heated at a temperature higher than the melting point of the drug for at least 5 minutes. With respect to the known techniques, the present invention allows to increase in the amount of drug incorporated into the carrier in amorphous form, and to increase the physical stability of the amorphous phase. This is particularly useful in the preparation of pharmaceutical compositions based on drugs which are crystalline in nature, such as are notoriously sparingly soluble in water: thanks to the increased amounts and stability of the drug in amorphous form, the resulting formulations have a more rapid and intense effect, and are endowed with greater bioavailability.

Abstract: L'invention concerne un procédé et un dispositif permettant d'évaluer la limite de cuisson de dhal et de riz avec une bonne reproductibilité. Les impulsions sont généralement consommées sous forme de dhals après une cuisson leur donnant une texture molle. La mesure de la limite de cuisson de dhals, du riz, etc. est très subjective et les procédés courants ne sont pas très satisfaisants. Un dispositif novateur et un procédé objectif permettant de mettre en oeuvre ledit dispositif ont été développés. Ce dispositif et ce procédé se basent sur le principe qui consiste à déterminer la zone d'étalement pendant la cuisson progressive des dhals ainsi que du riz et à lire le temps de cuisson sur une courbe tracée. Le dispositif développé à cet effet peut servir à exercer la force désirée afin de comprimer le grain cuit et la zone vers laquelle le grain s'étale est déterminée comme étant une zone d'étalement par le comptage du nombre de carrés sur un graphique approprié. Lorsque cette zone d'étalement est tracée en regard de la période de cuisson, une augmentation progressive est observée. Le moment auquel une augmentation soudaine est observée dans la zone d'étalement ou auquel un changement de la pente de courbe (déviation soudaine / stabilité) se produit est considéré comme temps de cuisson de l'échantillon (dhal / riz) en cours de cuisson. Le procédé selon l'invention développe les procédés instrumentaux standard. La présente invention fournit un procédé objectif et fiable qui permet d'évaluer la limite de cuisson du dhal et du riz avec une reproductibilité.

Abstract: A method and apparatus for accurately applying a cord (12) to a rotatable mandrel (14) utilizes control of cord length, rather than cord tension, as the control parameter. The apparatus includes a mandrel (14) with an inflatable diaphragm (54) mounted on an outer surface of the mandrel (14). The diaphragm (54) is selectively inflatable via a control valve (58) and source of pressurized fluid for dynamically adjusting a circumference of the mandrel (14) in response to a control input. The control input reads a tension in the cord (12) being wound. The cord (12) is positively fed to the mandrel (14) according to a defined algorithm based on the mandrel's shape, circumference and rotational speed, rather than by demand feed of the cord (12). The apparatus includes a positive feed control capstan (18) which is electronically geared. The apparatus further includes a cord-laying wheel (30) which isolates radially directed forces from circumferentially-directed forces. A second embodiment of the invention includes the belt being rotated on first and second pulleys (14A, 14B) while the cord (12) is applied. A center distance between the first and second pulleys (14A, 14B) is selectively adjustable to control cord tension in the cord (12).

Title: Sharp undercutter and undercutter fabrication
Inventor: CRICHTON TREVOR JOHN
IPC: B26B19/04
Filed: 2005-07-21
Granted: 2011-01-25
Abstract: This invention employs a serrated or scalloped edge (7) on the undercutter of an electric razor to enhance the shaving performance. This improvement is achieved by promoting hair capture and retention and reducing the cutting forces required to sever the hair. The serrations and/or scallops (9) help retain the captured hair, thereby increasing hair cutting efficiency. They also reduce the tendency for the hair to "roll" along the edge of the foil aperture until it is trapped in the aperture angle; this promotes a closer shave. A serrated edge can be generated by various methods. In this disclosure, several possible methods are described. The preferred method of fabrication is to generate a weld bead on the outer surface of an undercutter blade and grind back the bead to generate sharp edges along the weld bead. In doing so, the weld bead produces a serrated pattern. The geometry of the serration is determined by the geometry of the weld bead.
