Title: Oil-in-water emulsions
Inventor: DAHMS GERD H
IPC: B01F23/00
Filed: 1993-01-28
Granted: 2003-07-08
Abstract: An oil-in-water emulsion containing 0.5% to 30% metallic oxides having a particle size of less than 0.2 micron, less than 10% total emulsifier, 5% to 30% of an oil phase and at least 60% of an aqueous phase is provided.    The invention also makes available a method of preparing such emulsions in which the emulsion is formed by use of a dispersion in water of the metallic oxide particles.        By comparison with previously known emulsions of this type relatively small quantities of emulsifiers are used and it is possible to use an emulsion system with a low HLB value (e.g. less than 6). Preferably no hydrophilic emulsifiers are used.        The emulsions are suitable for preparing UV-absorbing compositions such as sunscreens, moisturisers and after-sun lotions. The ability to use no, or little, hydrophilic emulsifiers is advantageous since, in, general, these emulsifiers are not biodegradable whereas hydrophobic emulsifiers generally are biodegradable.

Abstract: A downhole adjustable orienting sub is included in a directional drilling tool string that is run into the borehole on coiled tubing. The bent housing of the tool string defines a bend angle and a bend point, and the bend point is oriented about the center of the bore by operating the orienting sub. The level of the reactive torque applied to the bent housing as the bit drills on bottom is controlled by selecting the amount of the weight of the coiled tubing that is applied to the bit. The orienting sub can be indexed downhole to provide different orientations of the bend point by temporarily reducing and then increasing the mud flow rate.

Abstract: A dual dispenser dispenses both soap and fragrance for washrooms, The dispenser has a mounting plate for mounting on a surface in the washroom and has a lower support for a box containing a flexible bag of soap with the bag having a flexible tube extending out of the box. A container with a fragrance source is mounted in the top of the box and a fan is located thereabove which is driven by a small motor mounted on an upper support of the mounting plate. A battery is also located on the box adjacent the fragrance container. Switch contacts are in circuit with the motor and the battery for operating the motor and fan when the switch contacts are closed. A cover for the mounting plate has a hand-operated actuating plate which squeezes the tube to dispense soap and closes the contacts to operate the fan when the actuating plate is pushed, thus dispensing both soap and fragrance in a single motion.

Abstract: A fluid pump (10) with rotary impeller (68) is disclosed which comprises an electromagnetically-driven (30), bearing five, seal-free rotary impeller (68) levitated by localized opposed, repulsive, permanent magnetic forces (60, 64) only. Levitation by lo-calized opposed magnetic or magnetic and fluid forces (52) of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping me-chanisms which can be of importance in pumping of physiological fluids such as blood. The levitating forces of the present in-vention are applied repulsively both axially and radially with respect to the impeller and are auto-adjusting, such that any at-tempted displacement of the impeller will automatically incur a corrective change in levitating forces. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.

Abstract: A lubrication system for the helical gear thrust washer, helical gear journal and inter-axle differential in tandem drive axles. The leading drive axle input shaft is journalled in a bearing supplied on one side with a gravity flow of lubricant from a passage receiving lubricant slinging from the power divider periphery, which receives lubricant slinging from the axle ring gear. The opposite side of the bearing has an annular lubricant chamber therearound formed by an annular baffle member surrounding the input shaft on the interior side of the bearing. The bearing is operative to pump lubricant to the annular chamber. An axial passage formed through a portion of the input shaft communicates the annular chamber with the differential gears. In one form the annular baffle member rotates with the input shaft and in the other form it is stationary. In some embodiments the baffle has an elastomeric lip seal therearound; and, in the other embodiments, the baffle defines an annular labyrinth passage restricting return flow to the sump from the annular chamber.

Abstract: Agents for enhancing the contrast in a diagnostic ultrasound procedure comprise colloidal dispersions of the liquid-in-liquid type, i.e., emulsions or microemulsions, in which the dispersed liquid phase is a liquid having a boiling point below the temperature of the animal to be imaged and which undergoes a phase change from a dispersed liquid to a highly echogenic dispersed gaseous foam or kugelschaum following administration to the animal. The liquid state of the dispersed phase allows one to manufacture extremely stable, pharmaceutically acceptable emulsions with particle sizes typically below 1000 nm. The gaseous state at body temperature yields highly echogenic microbubbles, typically below 10,000 nm in diameter, which are effective as ultrasound contrast agents. Intravenous, intraarterial, oral, intraperitoneal, and intrauterine dosage forms, methods of administration, and imaging techniques are described.

Granted: 1999-01-26
Abstract: At the initial diagnosis of sepsis (6-24h before the development of ARDS), serum manganese superoxide dismutase (MnSOD) levels and catalase activities are increased in septic patients who subsequently developed ARDS compared to septic patients who did not develop ARDS. Increases in MnSOD and catalase may be used to predict the occurrence of ARDS in septic patients with the same sensitivity, specificity and efficiency as parallel assessments of serum lactate dehydrogenase (LDH) and Factor VIII levels. Evaluation of serum MnSOD and catalase as well as these other accessible markers facilitates identification of subsets of patients and allow prospective treatment of septic patients who are destined to develop ARDS.
