Title: Microemulsion preparation containing a slightly absorbable substance
Inventor: TAKAHASHI MASAO
IPC: A61K9/107
Filed: 1994-04-19
Abstract: Microemulsion preparation in which a plurality of specified surfactants are combined such that aqueous-phase droplets that contain a physiologically active substance of low absorption and which have an average size of 0.4 -100 nm are dispersed in an oil-phase dispersion medium.          In order to improve its low transdermic or transmucosal absorbability, the physiologically active substance is allowed to be present as dissolved in the aqueous-phase droplets in the W/O emulsion.  The preparation is low in local irritation and uses neither malodorous substances such as higher alcohols nor conventional absorption enhancers.

Filed: 1995-11-14
Abstract: A method is described for automatic loading and unloading of printed circuit boards on machines for electrical testing, consisting of feeding the circuits to be tested into a pick-up area (16), detecting the position of the single circuits and comparing the position detected with a correct reference position, transferring the circuits from the pick-up area (16) to a loading area (4) on the test machine, taking into account during transfer any deviation of the actual position of the circuit board from the reference position, so that the circuit is always picked up in the same way, to be set down in the pre-established region of the loading area (4), and unloading the tested circuits from said area (4) of the machine onto a discharge line (7) for good circuits and a magazine (17) for faulty circuits, depending upon the test result. An apparatus for carrying out the method is also described.

Patent CA-2166266-A1 (CA)
Title: Method of Analyzing Patient Medical Specimens with Improved Length of Analytical Run Determination
Inventor: WESTGARD JAMES O
IPC: G06F19/00
Filed: 1995-12-28
Abstract: In high volume laboratory analysis of patient medical specimens, control materials are inserted at periodical intervals (e.g. once per eight hours) and analyzed. If the results of the analysis deviate from the mean according to statistical rules, the run of analyses prior to the insertion of control materials has in the past been rejected, often causing a substantial loss of results because the control materials were not inserted sufficiently frequently. According to the invention the patient mean of a test is determined, and when the mean deviates from the predetermined mean by more than a selected amount, this determination is used, not to reject the run, but rather to trigger insertion and analysis of control materials. If the analysis of control materials shows that the run is in control, the analyses made prior thereto are reported and the run is resumed. If the control material analysis shows that the run is out of control, then the prior analyses are rejected.
Patent CA-2166622-A1 (CA)
Title: Fluid dosing arrangement and beverage dispensing system provided with such a dosing arrangement
Inventor: KOBOLD KLAUS JOSEF
IPC: G05D7/06
Filed: 1994-05-06
Abstract: An arrangement for dosing fluids, in particular liquid fluids such as beverages, has a flowmeter arranged in the fluid dosing duct, in particular an impeller flowmeter, an on-off, preferably electric valve arranged in the dosing duct, for example downstream of the flowmeter, for releasing or cutting the flow of fluid, and an evaluation circuit that transmits a switching off signal (closing signal) to the on-off valve when a predetermined amount of fluid has pased through the flowmeter. In order to improve the dosing accuracy, a sensor is associated to the flowmeter for sensing the speed of flow given for example by the frequency of rotation of the impeller and for supplying to the evaluation curcuit a preferably electric sensor signal that corresponds to the speed of flow. The evaluation circuit supplies a preferably electric switching off signal to the on-off valve when the sensor signal falls below a predetermined lower value or exceeds a predetermined upper value. Also disclosed is a beverage dispensing system provided with such a dosing.
Patent CA-2170660-A1 (CA)
Inventor: GENSHAW MARVIN A
IPC: G01N33/72
Filed: 1996-02-29
Abstract: Apparatus and method are provided for determining the concentration of an analyte in a fluid test sample by applying the fluid test sample to the surface of a work- ing electrode which is electrochemically connected to a reference electrode which surface bears a composition comprising an enzyme specific for the analyte. A media- tor is reduced in response to a reaction between the ana- lyte and the enzyme. An oxidizing potential is applied between the electrodes to return at least a portion of the mediator back to its oxidized form before determining the concentration of the analyte to thereby increase the accuracy of the analyte determination. Following this initially applied potential, the circuit is switched to an open circuit or to a potential that substantially re- duces the current to minimize the rate of electrochemical potential at the working electrode. A second potential is applied between the electrodes and the current gener- ated in the fluid test sample is measured to determine analyte concentration. Optionally, the accuracy of the analyte determination is further enhanced algorithmi- cally.

Title: Porte-outil rotatif a systeme fixe d'alimentation de lubrifiant par le moyeu
Inventor: MEACHUM DONALD E
IPC: B23Q1/00
Filed: 1995-03-10
Abstract: Un porte-outil rotatif (1) comporte un système d'alimenation de lubrifiant fixe (60) dirigeant un courant lubrifiant non rotatif, traversant le moyeu, dans un alésage (82) acheminant le lubrifiant dans un outil de coupe rotatif (25). Le porte-outil rotatif (1) comprend un corps fixe (3), un arbre moteur (5) comportant une extrémité d'entraînement (13) montée rotative dans le corps (3), et un serre-outil (17) monté rotatif sur un côté opposé du corps (3) afin de retenir et faire tourner l'extrémité d'un outil de coupe (25). Le système (60) du lubrifiant du porte-outil (1) comprend un ensemble ajutage (70) monté inamovible dans le corps (3) et pourvu d'un ajutage (76) dirigeant un courant non rotatif de lubrifiant dans le canal (82) de l'outil (25), et un conduit fixe (48) acheminant l'écoulement de lubrifiant d'une source (63) de lubrifiant sous pression à l'ensemble ajutage (70) tout en isolant cet écoulement des composants en rotation du corps (3). Un ensemble de transmission (100) est ménagé dans le corps (3) pour transmettre une force rotative de l'arbre moteur (5) au serre-outil (17). L'ensemble ajutage fixe (20) évite à l'écoulement de lubrifiant d'entrer en interférence avec les forces centrifuges que les composants en rotation du corps (3) appliquent normalement sur l'écoulement, et cette non-interaction au niveau du conduit d'amenée (48) du lubrifiant rend superflu, d'une part, l'emploi d'un dispositif de joints dynamiques fluides entre le corps (3), l'arbre moteur (5) et le serre-outil (17), dispositif qui fuit et crée un effet de friction, et, d'autre part, la filtration des microparticules du lubrifiant soumis à une recirculation.

Title: Improved ratchet wrench
Inventor: WEI HUNG-YIN
IPC: B25B13/46
Filed: 1996-12-10
Abstract: An improved ratchet wrench includes an upper plate, a lower plate, a base disposed between the upper plate and the lower plate, two ratchets, two trigger blocks, two springs and two baffle elements.   Both the upper plate and the lower plate have at least a bent portion at one end thereof. The distance between a middle portion of the upper plate and a middle portion of the lower plate is smaller than the distance between an upper bent portion and a lower bent portion of  the plates,  such that the distance between the middle portions is equivalent to the distance between the bent portions of the upper and lower plates multiplied by a cosine  of  the  angle  of  the  bend.    By  such  an arrangement,  the upper plate and the lower plate are identical in shape and length, and hence manufacture of the ratchet wrench may be speeded up and costs reduced.
