Abstract: La présente invention concerne des méthodes de mesure de la régulation de l'état d'accoutumance aux analgésiques narcotiques. La mise en pratique de l'invention permet de classifier les composés de test par leurs effets sur l'état activé du récepteur  mu  des opioïdes. Dans une forme d'exécution, on traite les cellules réceptrices  mu  des opioïdes avec une composition de test faisant l'objet de recherches, on détermine la propension de la composition de test à produire une montée spontanée de l'AMP cyclique et la montée de l'AMP cyclique induite par un agoniste inverse, ce qui sert de mesure indirecte du risque d'accoutumance. Une montée de l'AMP cyclique induite par l'agoniste inverse signifie qu'il y a présence de ce que l'on appelle un état d'activation constitutionnelle des récepteurs  mu  des opioïdes. L'utilisation de ces méthodes a permis l'identification de composés qui ont les effets désirés sur l'activation constitutionnelle des récepteurs  mu  des opioïdes. Le potentiel thérapeutique de tels composés comprend le traitement de patients qui souffrent d'une accoutumance à un analgésique narcotique, qui ont pris une dose trop forte d'un analgésique narcotique ou dont la douleur est soulagée par un analgésique narcotique.

Title: Data reading device using semiconductor laser
Inventor: BOGDAN ALEXEI
IPC: G06K7/10
Filed: 1996-01-31
Abstract: A data carrier such as a card, disc, or badge, may have digital data encoded in a surface thereof, or in a plurality of stacked transparent surfaces,where the data is encoded as either positive-going or negative-going surface irregularities.  The data may be decoded from the surface by passing the data-carrying surface beneath a focusing lens through which light from a single wavelength laser diode is directed at the surface.  Light from the surface is reflected back through the focusing lens to the single wavelength laser diode, where that reflected light impinging on the laser diode causes interference at the pn junction within the diode.  If, at the same time, alternating current is being passed through the diode ? say, at 1.5 MHz ?, then the current anomalies occurring in the diode as a consequence of the pn interference may be detected such as by the voltage drop across a shunt device in series with the diode.  A signal is derived which is indicative of the current anomalies, and it together with the alternating signal are fed to a mixer.  The product of that mixer can be decoded such as by fourier analysis, delta analysis, or transient analysis, and so on. The resultant signal may also be fed through a filter before being analyzed.The result is that a data reading device having the laser emitter and data detector mounted in a single unit is provided.  By filtering and/or such as fourier analysis, the reflection from one or other of several data carrying surfaces maybe decoded, provided that each data-carrying stratum is transparent, at least tothe light emitted from the single wavelength laser diode.

Title: Sliding banjo cam lock for lathe
Inventor: CLAY TYMEN
IPC: B27C7/06
Filed: 1996-02-21
Abstract: A mechanism for clamping a banjo toolrest or toolrest bracket to a lathe bed which makes use of a sliding cam which is actuated by a drive shaft. The cam is supported independently of the drive shaft by a support block resting on a ledge which is formed in the base of the banjo. The cam is slidable with respect to the drive shaft along the length of this ledge on the banjo. This structure allows for sturdy clamping with minimal deflection at a predicable catching position along the length of the banjo rest. An eye bolt is used to connect the cam to a clamping plate which is positioned below two, spaced-apart rails extending along the top of the lathe bed. The banjo rest has a generally open bottom through which the shank of the eye bolt extends. Opposite ends of the drive shaft are rotatably supported by end walls of the banjo rest.

Title: End-of-life indication system for implantable pulse generator
Inventor: GRANDJEAN PIERRE A
IPC: A61N1/36
Filed: 1994-08-26
Abstract: An end-of-life (EOL) indicator for an implantable pulse generator (IPG)- especially of the neuromuscular stimulation variety - indicates an approaching battery EOL condition via an electrocardiogram (ECG) by changing the nature of the muscle stimulation burst signals. IPG internal circuitry detects an approaching EOL condition and modifies the burst signals by, for example, decreasing the number of pulses in a burst, increasing the heart contractionto-powering-muscle contraction ratio, or alternating between two numbers of pulses in successive burst cycles. The approaching battery EOL condition can be easily ascertained via trans-telephonic monitoring by analyzing a transmitted ECG alone for the above-mentioned burst signal changes. By observing the patterns in the ECG caused by the burst signal changes, a clinician could be aware of an approaching EOL without having known the original muscle stimulation burst signal parameters.

Title: Process for the purification and crystallisation of iopamidol
Inventor: HEGGIE WILLIAM
IPC: C07C231/24
Filed: 1996-06-06
Abstract: The present invention describes a process for the purification and crystallisation of Iopamidol, wherein 1-propanol, or 2-propanol, is added to an aqueous solution ofIopamidol followed, if necessary, by azeotropic distillation to reduce the quantity of water in relation to the quantity of propanol, and thereby ensure an high yield. The aqueous solution can be prepared either by the dissolution of crude Iopamidol inwater or directly from the reaction in which the Iopamidol is formed.   The present invention presents advantages for the routine production of Iopamidol since the crystallisation is straightforward to perform, can be easily controlled and is reproducible at an industrial scale.

Abstract: At the end of a wash program in a dishwasher, a drying cycle runs to dry the objects being washed.  The parameters for the drying cycle, such as the drying time (t?) and activation of extra heat energy is a heater (Hzg), are set depending on the amount of water necessary to wet the objects being washed and on the value of the a gradient for the temperature increase when the rinse liquid is being heated.
