Title: Method and apparatus for pressure, volume and temperature measurement and characterization of subsurface formations
Inventor: LEDER JOHN T
IPC: E21B49/00
Filed: 1993-06-18
Granted: 2003-11-25
Abstract: A method and apparatus for conducting in situ tests on a sub-surface earth formation (II) of interest which is traversed by a well-bore (10). A wireline formation testing instrument (13) is positioned at formation depth by winding or unwinding cable (12) from hoist (20), and a sampling probe (18) thereof is extended into fluid com-munication with the formation (11) and isolated from wellbore pres-sure. The sampling and measuring instrument (13) is comprised of a hydraulic power system (14), a fluid sample storage section (15) and a sampling mechanism section (16). Utilizing a hydraulically ener-gized double-acting bidirectional piston pump and by valve con-trolled selection of pumping direction, testing fluid such as comple-tion fluid may be pumped into the formation through the sampling probe either from fluid reservoirs of the instrument or from the well-bore. After reversing the operating and control valving of the pump and instrument, the piston pump is utilized to extract formation fluid from the formation (11) and pump it to sample tanks of the instru-ment (13), pump it to the wellbore (10) or subject it to controlled pressure for real time formation testing and for formation characteri-zation.

Abstract: Apparatus for ventilating a fireplace having a combustion chamber within the interior of a building comprising an enclosure defining an air volume and a fan unit for generating a constant negative pressure region within the enclosure.  A venting passage communicates the enclosure with the combustion chamber of the fireplace such that the negative pressure within the enclosure draws combustion gases from the combustion chamber into the enclosure to ventilate the fireplace.  A valve is provided in the venting passage to control the flow of combustion gases to the enclosure.  With this arrangement, the fan unit is operated at a constant speed to generate a constant negative pressure within the enclosure.  There is no need to install an expensive variable speed fan to provide different levels of ventilation and, as long as the fan installed is sufficiently powerful to ventilate the enclosure, the valve can be used to adjust the ventilation of the fireplace combustion chamber via the enclosure.

Title: Time of last injection indicator for medication delivery pen
Inventor: CHANOCH LAWRENCE H
IPC: A61M5/31
Filed: 1995-06-05
Granted: 1999-12-28
Abstract: A medication delivery pen is provided with an indicator that displays the time of last injection through interaction between a cap and pen body assembly. When a user requires an injection the cap is removed from the pen and a dose is set by turning a dose setting knob to the desired dose as displayed in a window in the pen. After the desired dose is set using the dose setting knob, injection is achieved by pushing an actuator button.  After injection the user replaces the cap on the pen such that indicia on the cap align with indicia on the body of the pen to display the day and time of day of the last injection, thereby providing the user with means for remembering when the last injection was administered by aligning indicia on the cap with indicia on the pen body assembly, without having to otherwise write or record the day and time of the last injection.

Abstract: L'invention se rapporte à la séparation améliorée de terres organiques, hydrophobes, émulsifiées et d'effluents aqueux à l'aide d'un tensioactif carboxylate, amphotère, en combinaison avec des matières floculeuses ou déstabilisatrices cationiques. Ce traitement, combiné à un ajustement du pH acide, suscite la séparation rapide des terres organiques, hydrophobes du courant aqueux. Le courant aqueux, traité, est compatible à l'environnement. L'invention se rapporte également à des détergents améliorés pour lessive comprenant un tensioactif carboxylate, amphotère, organique et des tensioactifs non ioniques, sélectionnés, qui assurent le nettoyage d'articles en tissus et à base de fibres souillés par d'importantes quantités de terre organique. Le pH d'un effluent obtenu dans ces procédés de nettoyage peut être ajusté à un pH acide et traité avec une matière cationique, ce qui provoque une rupture et permet une séparation rapide et pratiquement totale des terres organiques hydrophobes et de l'effluent. Les concentrations résiduelles de terre organique dans l'eau de l'effluent peuvent être inférieures à 250 ppm et de préférence sensiblement inférieures à 100 ppm.

Granted: 2001-08-28
Abstract: A plasticized high water content cosmetic gel that will be sharpenable when used as a core inside of a sharpenable pencil barrel. The gel essentially comprises, by weight, about 25 - 42 % water; about 25- 35 % of a polyol or aliphatic diol vehicle such as a butylene glycol; about 4 - 12 % sodium stearate; about 0.1 - 2 % of a carboxylated acid ester plasticizer; about 4 - 28 % of a colorant; and about 0.1 - 1 % of a surfactant. To reduce syneresis, adding about 1 percent or less a viscosity increasing agent is effective. For water resistance when the cosmetic gel is applied to a user's skin, adding about 5 - 10 % of a styrene acrylic polymer waterproofing agent is effective, and does not increase irritation levels out of the mild range.

Abstract: In connection with instances of inter-exchange hand-off, certain hand-off related paramaters assigned to border cells within a first system area are evaluated (121, 124) and considered by the second system area in making the inter-exchange hand-off. To communicate these hand-off related parameters from the first system area to the second system area, a request (152) for the parameters is transmitted from a mobile switching center (18(1)) serving the second system area to a mobile switching center (18(2)) serving the first system area. Responsive thereto, the mobile switching center for the first system area retrieves (154) and delivers (156) the requested parameters for subsequent second system area mobile switching center processing in connection with making the inter-exchange hand-off determination. Alternatively, the mobile switching center serving the first system area acts on its own to retrieve (162) and send (164) certain hand-off related parameters to the mobile switching center serving the second system area for subsequent use in connection with making the inter-exchange hand-off determination.
