Title: Method of controlling press power in a limbing knife assembly in a single-grip harvester head
Inventor: JOHANSSON ANDERS
IPC: A01G23/083
Filed: 2001-09-13
Abstract: In a method, when using a single-grip harvester head for felling and processing trees, of controlling the press power which, by means of a limbing knife assembly (6), is exerted on a stem (3) which is horizontally fed through th head with its butt end first, the diameter of the stem is measured and the press power is reduced in accordance with a control diagram as the diameter decreases during the feeding. The measured diameter values are registered, and each measured diameter value is compared with a predetermined diameter value which is selected from the diameter values of the stem (3) which are previously registered during the feeding of the stem. If a measured diameter value is found to equal or be greater than this predetermined diameter value, the press power is increased to a corrective power value, which is maintained until a later measured diameter value falls below a reference value.

Title: Method for 2d inversion of dual laterolog measurements
Inventor: WANG HANMING
IPC: G01V3/38
Filed: 2001-09-25
Abstract: A 2D inversion of true formation resistivity from dual laterolog tool measurements is accomplished using a pre-calculated look-up table 104. An initial earth model is derived and divided into intervals 102. A 2D tool response is calculated in each interval using the earth model 108. Matching is checked between the calculated 2D tool response and the tool measurements 10 4. The following steps are iterated until the match is satisfactory. A 1D radia l tool response is derived in each interval using the precalculated look-up table 105. Shoulder bed effects are approximated in each interval by subtracting the 1D radial tool response from the 2D tool response 106. A non - linear least square optimization is applied at boundaries of the intervals a nd local maximum and minimum values in the intervals to update the earth model 107.

Abstract: La présente invention concerne un dispositif portatif destiné à émettre de l'énergie acoustique produite par un générateur ultrasonore et à lui faire traverser la surface extérieure de la peau d'un patient, en vue d'accroître la libération de composés biofonctionnels par un organe ciblé, afin de traiter une maladie ou une blessure. La présente invention se rapporte notamment à un moyen qui provoque la libération d'insuline par le pancréas du patient, afin d'améliorer le traitement du diabète. Le dispositif portatif est programmable pour ce qui concerne la fréquence acoustique, l'intensité et la durée, ce qui permet ainsi de réguler la quantité d'insuline, laquelle peut être programmée pour être libérée en réponse à la transmission sonore par le pancréas du patient. Le dispositif peut être programmé, en fonction des besoins, pour une transmission sonore fixe ou pour des transmissions impulsionnelles. Le dispositif est principalement destiné aux diabétiques du type 2, qui produisent de l'insuline naturelle mais pas nécessairement en quantités ou en temps voulus pour une biofonctionnalité efficace. Dans ce cas, la présente invention qui utilise des transmissions sonores, peut être utilisée pour induire artificiellement la libération appropriée d'insuline par le pancréas du diabétique, en l'absence ou en présence d'une médication associée.

Abstract: La présente invention a trait à en ensemble de caloduc (10/110) sous vide et chargé d'un contenu de substance active, comportant, de manière générale, un évaporateur (12/112) apte à l'évaporation du fluide caloporteur et un condenseur (16/116). Le condenseur (16/116) comprend un réservoir (30/130), situé à une élévation supérieure à l'évaporateur (12/112), pour y recueillir le fluide caloporteur liquide. Un canal de retour de liquide discret et imperméable (36/136, 20/120) permet l'écoulement par gravité de la substance active liquide depuis le réservoir (30/130) vers l'évaporateur (12/112).
