Abstract:
A flexible plate for securing a microchip surface to the surface of a cooling device. The flexible plate allows for z-directional movement between the microchip subassembly having a circuit board and a semiconductor substrate, and the cooling device. The flexible plate is a compact, single piece design that provides constraints in alignment in the x-, y-, and theta-directions, while allowing for z-direction compliance and tilt compliance. The flexible plate has tabs for mounting the microchip subassembly and tabs for mounting the cooling device. The microchip tabs are opposite one another and the cooling device mounting tabs are opposite one another. The flexible plate is a one-piece construction made from sheet metal, plastic, or metal castings. The flexible plate has a band with all the tabs mounted on the inside of the band, or one set of tabs mounted on the outside of the band.
Abstract:
A pneumatic groundwater retrieving piston pump comprising generally of a piston and a foot valve is disclosed. A pneumatic driver slides the piston assembly up and down inside the foot valve assembly, which is connected to the driver by means of a stationary length of pipe. The drive shaft of the pneumatic driver is connected to the piston assembly by means of a polypropylene coated epoxy resin based rod. On the upward stroke the foot valve opens and lets water enter the volume below the piston assembly and the piston assembly check valve is closed and lifts the column of water. On the down stroke the foot valve closes holding the column of water and the piston check valve open, and allows the water to pass through to recharge the cylinder for the next lift cycle.
Abstract:
Spray-dried particles having improved protein stability are produced by spray-drying a mixture including a protein, a phospholipid and an organic-aqueous co-solvent. Spray-dried particles which include at least 1 weight % phospholipid, having a tap density of less than 0.4 g/cm3 can be prepared. The particles can be delivered to the pulmonary system of a patient.

Abstract:
Particulate compositions for delivery, preferably pulmonary, which provide sustained release of antigens, preferably DNA and/or peptide and/or protein antigens, have been developed. In the preferred embodiment, aggregate nanoparticles are in the aerodynamic range of 1-5 microns diameter and fly deep into the lungs. As the aggregate particles degrade in the body, MSP-1 and AMA-1 proteins are released into the blood stimulating a humoural immune response. The individual particles in the range of 0.1 micron are preferentially phagocytosed by APCs which express the proteins encoded by AMA-1 and MSP-1 plasmid DNA thereby initiating the cellular immune response that is necessary for a complete immunity.
Abstract:
A method and compositions for targeted drug delivery have been developed. The compositions include a targeting molecules such as a hormone that specifically binds to a receptor on the surface of the targeted cells; a drug to be delivered, such as a toxin that will kill the targeted cells; and a nanoparticle, which contains on or within the nanoparticle, the drug to be delivered, as well as has attached thereto, the targeting molecule. Nanoparticles can consist of drug or drug associated with carrier, such as a controlled or sustained release materials like a poly(lactide-co-glycolide), a liposome or surfactant. The compositions are administered by injections in most cases, although compositions can be applied topically orally, nasally, vaginally, rectally, and ocularly. Compositions can also be administered to the pulmonary or respiratory system, most preferably in an aerosol.
Abstract:
A method of making an embossed optical sheet material includes: providing an optically anisotropic, uniaxially oriented polymer substrate having a first major surface and a second major surface; heating a patterned tool using radiant energy from a radiant energy source, wherein the pattern comprises a plurality of parallel raised microstructures having a longitudinal direction; pressing the tool against the first major surface of the polymer substrate such that the longitudinal direction of the raised microstructures is substantially parallel to the direction of orientation of the polymer substrate, to soften the first major surface of the polymer substrate and emboss groove-shaped microchannels into the polymer substrate; cooling the embossed polymer substrate; and separating the tool from the polymer substrate; wherein the orientation of the polymer substrate is unchanged throughout the polymer substrate and first major surface.

Abstract:
A solvent system for use in acidizing and cleanup in oil wells and gas wells. The solvent system comprises a substantially water-soluble alcohol, such as methanol, or ethanol or any mixture thereof, a substantially water/oil-soluble ester, such as one or more C.sub.2-esters through C.sub.10-esters and a substantially water/oil-soluble ketone, such as one or more C.sub.2-ketones through C.sub.10-ketones.
Abstract:
The present invention provides a rotating antenna that can be used in combination with a coded modulated transponder as part of a vehicle positioning and tracking radar system. The antenna transmits a pair of frequency-modulated continuous-wave (FMCW) electromagnetic signals that have a vertical polarisation, for example. The transmit signals are incident on the transponder which returns or transmits an electromagnetic signal back to the antenna having a horizontal polarisation, for example. The transponder can alter the polarisation of the incident transmit signals using a known technique. The transmit and receive feeds at the antenna are cross-polarised and are therefore isolated from each other.
Abstract:
Inhalation device and associated method for facilitating inhalation by a patient of powder medicaments contained in a receptacle. The inhalation device has a chamber for receiving the receptacle. A ring is circumferentially coupled to an inner surface of the chamber to achieve a higher reproducible emitted dose of medicament from the receptacle. The inhalation device also includes an improved implement for puncturing the receptacle, requiring less force and experiencing fewer failures. The inhalation device also includes a means for indicating readiness.
