Patent WO-0120186-A1 (WO)
Title: Systeme permettant de reduire l'effort necessaire a l'actionnement d'une pedale d'embrayage pour vehicules a moteur
Inventor: DO CARMO PINTO EMYGDIO JOSE
IPC: B60K23/02
Filed: 2000-05-19
Abstract: L'invention concerne un système permettant de réduire la force nécessaire à l'actionnement d'une pédale d'embrayage d'automobiles, cette pédale d'embrayage (2) étant fixée à l'extrémité d'un bras d'actionnement (1) qui comporte, au niveau de son autre extrémité, un axe de pivotement (3) faisant partie intégrante de l'extrémité libre d'une tige (4), ledit bras d'actionnement (1) pouvant également pivoter autour d'un axe de pivotement (6) situé entre ses extrémités et fixé à la carrosserie du véhicule (non représentée), de façon qu'une force appliquée sur la pédale (2) entraîne l'actionnement de l'axe de pivotement (3) situé à l'autre extrémité du bras d'actionnement (1) par pression sur la tige (4) du piston plongeur du maître-cylindre d'embrayage (5). Cette invention permet de réduire la force d'actionnement grâce à un système dans lequel le bras d'actionnement (1) définit un chemin de rotation (A) autour de l'axe (6) après l'actionnement de la pédale (2), de l'axe de pivotement (3) et donc du bras de levier (X), la force étant exercée sur la tige. Le composant du bras de levier (X), qui influence le moment appliqué à l'axe (6), diminue lorsque le bras de levier suit le chemin (A), d'où une réduction du moment et de l'effort requis par l'organe d'entraînement pour actionner l'embrayage. Par ailleurs, le maître-cylindre (5) peut lui-même pivoter autour d'un axe (9) fixé à un support (10) sur la carrosserie du véhicule, ce qui permet à la tige (4) de recevoir l'axe de pivotement (3) lorsque ce dernier suit le chemin (A), la tige (4) pouvant ainsi pénétrer davantage dans le maître-cylindre (5) de l'embrayage.

Filed: 2001-09-06
Abstract: La présente invention concerne un produit composite à base de crevette qu'on peut préparer de manière à ce qu'il ressemble globalement du point de vue de la tenue sous la dent et de l'aspect à une crevette naturelle entière non traitée, ainsi qu'un procédé de préparation de ce produit au moyen d'un liant durcissable à température ambiante. Le produit renferme des morceaux de chair de crevette plutôt que d'être entièrement constitué de chair hachée ou émulsifiée, ces morceaux étant reliés par des liaisons qui sont fortes et stables et qui se forment sans température élevée, ceci permettant de préparer le produit final et de le proposer au consommateur à l'état cru non congelé. Ce produit peut également être congelé ou cuit sans réduire l'intégrité de la liaison. Enfin, le produit selon la forme préférée de l'invention a la forme, l'aspect, les propriétés de tenue en main et de comportement en bouche d'une crevette naturelle entière crue ou cuite. Ce produit peut par conséquent être vendu nature ou enrobé avec une panure ou une pâte par exemple.

IPC: A61M1/10
Filed: 1989-11-20
Abstract: ABSTRACT    A dual chamber pumping apparatus and method for infusing fluids to a patient includes a disk having a fluid inlet and a fluid outlet.   Resilient membranes are attached to opposite sides of the disk to establish dual pumping chambers, and a network  of  one-way  valves  connects  the  fluid  inlet  in alternating fluid communication with the pumping chambers.   A one-way outlet valve connects the pumping chambers alternately in fluid communication with  the  fluid outlet.   The one-way valves utilize a hollow, elastomeric tube fixedly disposed in passageways  within  the  disk  for  covering  and  uncovering respective ports in response to fluid pressure differentials on the  inner  and  outer  surfaces  of  the walls  of  the  hollow, elastomeric tube.

Abstract: INTRAORAL MEDICATION RELEASING SYSTEM                               ABSTRACT            A system for long term releasing of medication in the mouth, and especially an intra-oral fluoride releasing system (IFRS) for releasing fluoride over a long term for inhibiting the formation of caries in the teeth.  The system uses a holder for retaining and protecting intra-oral fluoride tablets or other intra-oral medicament in the form of fluoride releasing devices (IFRD). The holder has a plate with retaining sides and retaining posts or a carrier.  The tablet will fit within the holder.  The tablet may be located in the carrier, or ligature bands can be tied around the tablet in order to releasably hold the IFRD within the holder.  The system causes a level of fluoride to be maintained over a long term within the mouth which has been found chemically effective for caries control and without causing severe irritation to oral tissues.

Title: Conduction sensor system for multiple scr bridges
Inventor: PEARSON WILLIAM R
IPC: H02H7/125
Filed: 1990-03-22
Abstract: Case 3042 CONDUCTION SENSOR SYSTEM FOR MULTIPLE SCR BRIDGES            ABSTRACT OF THE DISCLOSURE       A multiple bridge system for providing DC power from a three phase AC power line.  Each bridge in the system has six legs arranged in pairs of legs. Each leg has at least one SCR having a gate electrode, and each pair has the SCRs in series across a positive and a negative bus which provides the DC output.  The common point between each pair of legs is connected by a respective first, second and third conductor to a respective conductor in the power line.  A computer has means for providing gating signals to each gate electrode at an appropriate time and for temporarily storing information relating to the gating signals.  A sensor on each of the first, second and third conductors provides a signal representing current flow in the respective conductor.  The computer samples the signals from the sensors at a predetermined time when each leg should be conducting current according to the information stored relating to the gating signals, and if there is no indication of current flow in a leg for at least two consecutive times when there should be, the computer provides an alarm signal and may reduce the output.  The operation of the bridge system continues until such time as two corresponding legs in two bridges have failed.

Abstract: TITLE            SEROLOGICAL DETECTION OF CATTLE GRUB INFESTATION                         INVENTORS                      ROBERT W. BARON DOUGLAS D. COLWELL                 ABSTRACT OF THE DISCLOSURE           A relatively early detection of cattle infesta-tion with larvae of warble flies e.g. Hypoderma lineatum and H. bovis, is essential for determining the prevalence of cattle grub infestation and thus for an economical cattle treatment (vaccination) program.  A known detec-tion method based on ELISA (enzyme-linked immunosorbent assay) has proven effective in such early detection, but not selective enough to differentiate between infested and vaccinated cattle.  An improvement of the method is proposed which involves the use of selected culture-derived antigens rather than crude proteinaceous extracts isolated directly from biological material.
