Abstract: The invention relates to a novel display system for a drug delivery device that reduces power consumption and permits the user of the device to see messages when the device is not in a powered state or when the device has encountered an error condition. By using a bistable display, the medical device is able to maintain messages that can been seen by the user even when the device's power supply is exhausted or when the device has encountered an error that interrupts its normal operation. The use of such a display also improves the battery life by eliminating the need to provide power to the display screen when it is not being updated.

Abstract: An infusion device comprising an infuser base, a cannula and a ferrule. The infuser base having a bore extending therethrough, the bore having distal and proximal ends and defining a shoulder therebetween. The cannula having distal and proximal ends, the proximal end having an inside first diameter. A flange extends radially outward from the cannula proximal end. The cannula is positioned in the bore such that the flange is positioned adjacent the shoulder. The ferrule has an insertion portion, having an outside second diameter which is substantially equal to the first diameter, and a tapered portion extending from the insertion portion. The ferrule is positioned in the bore such that the insertion portion and a portion of the tapered portion are received in the cannula proximal end and the flange is compressed between the shoulder and the tapered portion to define a seal between the cannula and ferrule.

Abstract: Described is a keypad and its method of manufacture. In one embodiment, a keypad is provided that includes a substrate having a plurality of donut-shaped recesses located at each site of a button for inputting user information, a plurality of cushions each filled with an incompressible fluid (e.g., water), a flex circuit layer, a plurality of metal membranes and an over-molded thermoplastic elastomer layer. During the over-molding of the thermoplastic elastomer layer, the plurality of cushions filled with an incompressible fluid prevents collapse of the space between the flex circuit layer and the plurality of metal membranes. After the layers of the keypad are assembled, the incompressible fluid is removed which leaves a space between the flex circuit layer and the plurality of metal membranes.

Abstract: A system employing an integrated analyte test strip including a biosensor and lancet is disclosed. The integration of lancet and the sensor elements eliminates the need to align the sensor to the biologic fluid sample after a lancet and lancing device are used in combination to pierce the skin. The system preferably includes a device comprising two body portions that slide relative to each other to both cock and fire a test strip at a target site. Meter reading and test strip disposal may be accomplished by removing the device from the target site. The device preferably employs a magazine loaded with test strips, with one strip being taken from the magazine each time the device is actuated. It preferably also includes a magazine in a cap to store spent test strips for disposal. The device may be turned on an off simply by removal and return of the cap.

Abstract: A detergent or disinfectant composition comprising is presented having 0.5 to 10 percent by weight of an activator compound which under perhydrolysis conditions forms a percarboxylic acid, and releases a leaving group capable of being used as a substrate for enzymes, and up to 50 percent by weight of a peroxygen compound. The composition increases the oxidation of peroxide compounds in oxidation, bleaching, detergent, cleaning and disinfecting solutions, especially at low temperatures.

Abstract: A resin coating is formed on a metal surface using an aqueous autodepositing resin composition that contains oxidizing agent, acid, and carboxyl-functional and/or hydroxyl-functional water-dispersible or water-soluble resin and, optionally, metal ions; the resulting coating, while still in its uncured condition, is subject to post-treatment with an aqueous solution containing from 0.5 to 5.0 g/L of amine and from 10 to 100 g/L (solids) of water-soluble amino resin molecules that bear at least two alkoxymethylamino, methylolamino, and/or imino groups; and the coating is then dried and cured. This provides a highly anticorrosive coating on the metal, and contrary to an analogous process in which the post-treatment solution contains amino resin but not amine, the post-treatment solution remains stable and provides continuing high quality coating performance even after a considerable amount of metal surface per unit volume of post-treatment solution has been processed.

Abstract: A molded synthetic composition is presented having at least 25% by weight synthetic surfactants, at least 30% by weight non-surface-active organic plasticizers and fillers, and 5 to 30% by weight of talcum. The composition provides improved moldability and initial foam quality.

Abstract: Strong alkaline cleaning solutions and concentrates therefor can be prepared without using any phosphorus or nitrogen containing surfactants by combining a weak carboxylate surfactant with at least one, or preferably both, of an aliphatic alcohol alkoxylate nonionic surfactant and an alkyl phenol alkoxylate nonionic surfactant. The predominant alkoxylates in the nonionic surfactants are ethoxylates, but at least the non-aromatic based surfactant preferably contains some propoxylate also.

Abstract: The invention relates to the utilization of onium aldehydes and onium ketones of formula (1) or the derivatives thereof. In the formula, R1 represents a hydrogen atom, a (C1-C4)-alkyl group, an aryl group or a heteroaryl group. R2, R3, R4, independent of one another, each represent a hydrogen atom, a halogen atom, a (C1-C4)-alkyl group, a (C1-C4)-alkoxyl group, hydroxy-(C1-C4)-alkoxyl group, hydroxyl group, nitro group, aryl group, trifluoromethyl group, amino group or (C1-C4)-acyl group. Said amino group can be substituted by (C1-C4)-alkyl groups. Two of the residuals can be combined to form a fused benzene ring. R5 represents a (C1-C4)-alkyl group, aryl group, alkylaryl group or heteroaryl group.

The filter is particularly suitable for the production of drinking water from ground water in surface mining regions.

Abstract: A tri-laminate body panel stiffener includes two polymer layers with or without a backing. One of the layers is a compliant foam layer mounted against a substrate while the other layer is a rigid foam layer mounted against the compliant foam layer.

In the process of using this solution, hydroxylamine ions become depleted or reduced in concentration in the applied solution. A replenishing solution is added for reusing the solution until the replenished coating solution reaches a sulfate level of no more than 14 g/l.

Abstract: A coating apparatus is disclosed for applying a coating material on one or more zones of a substrate material. In one embodiment, the coating applicators have fluid-wicking strips that apply the coatings directly to the substrate, while in another embodiment, the fluid-wicking strips indirectly apply the coatings to the substrate via feed rolls. Metering mechanisms supply predetermined amounts of coating material to the fluid-wicking strips. Each coating applicator has a housing with a recess for receiving one the fluid-wicking strips therein. One of the fluid-wicking strips Is mounted in each housing which has a plurality of transversely spaced passageways. Each passageway of each applicator housing is fluidly coupled to its own separate air actuated metering mechanism which dispenses coating material to the portion of the fluid-wicking strip adjacent thereto. A desired quantity of coating material is simultaneously delivered via the metering mechanisms to each of the applicator housings.

The substrate may, for example, be a metal vehicle door. The thermosettable adhesive is comprised of at least one polyol such as a polyether polyol, at least one epoxy resin, and at least one polyisocyanate.

A biocide to repress the growth of micro-organisms in the dispersions is preferred.
