Embodiments of the invention relate to a combustor flow sleeve for a turbine engine. According to aspects of the invention, the flow sleeve can be attached to one of the components in the combustor head-end by a plurality of fasteners. In one embodiment, the flow sleeve can be attached directly to the combustor head-end component by a plurality of bolts. The bolted flow sleeve can reduce the time to install or remove the flow sleeve. In certain areas, it may not be possible to directly attach the flow sleeve to the combustor component. A flow sleeve according to aspects of the invention can be adapted to facilitate indirect attachment to the combustor head-end component. The flow sleeve can further be adapted to include thermal relief slots to accommodate any differential thermal expansion or contraction between the flow sleeve and the component to which the flow sleeve is attached.

Combustor flow sleeve attachment system

A device for minimizing the absorption of pathogens collected on a person's hands by contact between the hand and the face of said person, includes a barrier placed in the crook of the elbow that limits the flexion of the elbow as the hand approaches the face. In an alternate embodiment of the invention, a proximity sensor is positioned on a part of the person's body to sense and warn the person that a hand is about to touch the face. An audio or visual warning signal or a mechanical or electrical stimulation may be triggered by the output of the sensor. A method is also provided for progressively weaning the person from reliance on said devices.

Contamination avoiding device

A high performance lubricant that includes a silicone wax that has been dissolved in solvent, emulsified or suspended in an inert carrier is described. In addition, a method is discussed of lubricating the solid surfaces of moving parts with a relatively water resistant, dry lubricant. The lubricant repels water and sheds dirt. Thus, this lubricant is particularly useful for lubricating high performance products that are used in a dirty environment.

Silicone wax-based dry lubricant

A light-duty, multi-purpose lubricant particularly formulated for use on the diverse bearing surfaces mechanisms which operate in a dirty or dusty environment, such as bicycle chains. The lubricant comprises an insoluble bond weakening agent, preferably metallic soaps such as Calcium Stearate, in suspension in a volatile solvent-based solution of wax and oil. After application and evaporation of the solvent the composite dry lubricant exhibits good penetration and load bearing properties without the dirt-retaining character of oils or greases. The undissolved particles of the bond weakening agent combine with dirt particles to break-down portions of the lubricant into a dry flaky particles which are sloughed off the mechanism. Soluble waxes having different solid phase crystalline structures may be blended with the paraffin to reduce the rate of sloughing. The amount of solvent may be adjusted or eliminated depending on the application. A surfactant can be added provide for coating wet mechanisms.

Dry lubricant

A light-duty, multi-purpose lubricant particularly formulated for use on the, diverse bearing surfaces mechanisms which operate in a dirty or dusty environment, such as bicycle chains. The lubricant comprises an insoluble soap, preferably Calcium Stearate in suspension in a volatile solvent-based solution of paraffin wax, petrolatum and a surfactant. After application and evaporation of the solvent the composite dry lubricant exhibits good penetration and load bearing properties without the dirt-retaining character of greases. The optional surfactant is surrounded and deactivated by the other components so that the dried lubricant is water repelling. The undissolved particles of soap combine with dirt particles to break-down portions of the lubricant into a dry flaky dust which is sloughed off the mechanism. Soluble waxes having different solid phase crystalline structures may be blended with the paraffin to reduce the rate of sloughing. The amount of solvent may be adjusted or eliminated depending on the application.

Dry household lubricant

A reverse osmosis filtration device which comprises a flexible elongated membrane bladder spirally wrapped around a purified water duct in a series of spaced-apart coils supported about their edges by perforated spacers. The device is installed in a water supply conduit to extract a volume of purified water under typical household line pressure while allowing the brine-carrying feed water for other normal household usage such as clothes and dishwashing, toilet flushing, showering and bathing.

Spacerless feed channel membrane filter element

A split tube containing a lubricant is engaging a bicycle chain. The lubricator tube is carried by the chain during the initial chain operation until the tube end contacts a barrier surface on the chain drive mechanism. The barrier may be the pivoting idler arm, the derailer mechanism, or a portion of the bicycle frame. The device brings the lubricant in intimate contact with the chain allowing the use of semi-solid, liquid, and solid-solvent mixture of lubricants.

Continuous chain lubricating device

Water purification unit

A portable water container for holding water treated by reverse osmosis water purification, which container rests on a base. The base has a recess in which a reverse osmosis unit is laid, with water connecting means for supplying water to the portable water container and for providing an overflow. The reverse osmosis unit can be quickly and easily removed from the base by merely lifting the osmosis unit from the recess and pulling stopper type end connectors from the ends thereof. The walls of the recessed portion of the base restrains movement of the stopper end connectors from the osmosis units during use. Also a unique reverse osmosis unit is used that has activated carbon impregnated paper therein through which the water passes providing further water treatment.
