Abstract: Disclosed herein is a particle comprising a magnetic material and a carbon layer on the outer surface of the magnetic material. The carbon layer may comprise graphite, such as Graphite from the University of Idaho Thermolyzed Asphalt Reaction (GUITAR). The particle may further comprise a single stranded nucleic acid moiety, such as single stranded DNA or single stranded RNA, conjugated to the carbon layer. The disclosed particles are useful as nucleic acid sensors, PCR reagents, and in nucleic acid synthesis applications.

Abstract: Capsules that include a shell, a sensitizer, and an active material. Methods for using the capsules to spatiotemporally deliver active material. Representative shells include vesicles, polymers, and inorganic materials. Representative active materials include small molecules and proteins.

Abstract: A respiratory component mounting assembly includes a first respiratory component, a second respiratory component and a mounting clip for mounting the second respiratory component to the first respiratory component. Each of the first and second respiratory components includes at least two spaced apart clip openings. The mounting clip has an intermediate portion and two spaced apart free ends connected to the intermediate portion. The intermediate portion of the mounting clip is received within both of the clip openings of the first respiratory component and the free ends of the mounting clip are received in the clip openings of the second respiratory component for releasably securing the first and second respiratory components together.

Abstract: A method and system for performing biochemical detection or analysis on micro- and nano-scale subcellular component within a single biological cell is provided. An integrated platform device and method to perform the biochemical analysis is also provided.

Abstract: An irrigation pump for use in irrigating small fields or supplementing larger irrigation systems can also be used for portable water supply for emergency, military, or for underdeveloped countries. The pump system is designed to be light-weight and semi-portable and can be powered with a small engine or electric motor. The apparatus uses a down well impeller that is driven by a flexible vertical shaft and a vertical shaft motor drive or engine. The pump impeller incorporates its own thrust and journal bearings for the pump shaft. The bearings are water lubricated. The main drive shaft is flexible and elongated and is supported over its entire length with a flexible shaft guide sleeve. The flexible drive shaft is surrounded by a convoluted well pipe so that the drive shaft and the well pipe can be removed from the well casing bore as a unit and then coiled for storage. The drive shaft accepts couplings at each end and a seal at its upper end.

Abstract: A respiratory mask is provided with an eye shield having a body portion which is releasably-secured to the mask, and a shield portion which shields the eyes of the wearer. The shield portion is self-supporting on the body portion and, hence, on the mask, and includes a sheet of transparent, eye-shielding, material which can be replaced if it becomes marked or damaged. The shield portion can be pivoted forwards, relative to the mask, so that it is removed from the line of vision of the wearer without affecting the respiratory protection provided by the mask. A valve arrangement in the body portion of the eye shield can divert air from the mask into the shield portion, to remove contaminants from the region around the eyes of the wearer.

Abstract: A two-component foam spray gun is readily disassembled for cleaning. It includes a body (1) with reactant (12, 14) and purge gas (16) inlet ports. A moldable valve packing (32) inside the body has a tapered conical interior surface (142), and apertures which match the reactant ports. A valve/tip (40) has a conical outer surface (48) which mates with the valve packing (32). The valve/tip (40) is held in place by a moldable packing washer (34), held at non-constant pressure by a screw (36, 38). The interior of the valve/tip (40) houses a removable mixing chamber (50). The mixing chamber (50) has direct flow orifices (60) and an auxiliary flow path (58, 60) which ameliorate pressure surges. The spray gun can be disassembled for cleaning without disturbing the seal, by removing the valve/tip (40) to the rear, thereby breaking it free of the conical packing. Rotation of the valve/tip (40) relative to the body (1) shuts off the reactant flow, and starts the purge gas flow.

Abstract: A suspension system for a pivotal nozzle of a jet propelled vehicle having a gas generator operable to effect propulsion of the vehicle, the system comprising a plurality of actuators connected to the exhaust nozzle and operable to effect pivotal movement thereof to steer the vehicle in a desired direction. Each actuator comprises a movable member connectible on one side to a source of fluid power to effect nozzle movement with the other side of the member being interconnected with said other side of each other actuator movable member to form a fluid suspension for the nozzle. In use, the suspension is pressurized to produce a force acting on the nozzle in a direction opposite to the load imposed on the nozzle by the gas from the gas generator acting thereon.
