Abstract: An intraocular lens has a flexible lens body center portion formed from an optically clear material surrounded by an outer ring which is sensitive to an external force, such as a magnetic force. Utilizing the external force, the shape of the outer ring can be changed to elongate the lens body along a predetermined axis for correcting astigmatism. The outer ring can also be used to change the power of the lens by altering the spherical shape or curvature of the lens. Attached to one of the lens body and the ring is a plurality of actuator bodies of ferromagnetic material which are either permanently magnetized by the external force or are temporarily magnetized and the altered shape is retained by a shape retainer attached to the ring.

Abstract: The corespun yarn is formed on a friction spinning apparatus and comprises three components, including a core of high temperature resistant fibers, a core wrapper of low temperature resistant fibers surrounding and covering the core, and an outer sheath of low temperature resistant fibers surrounding and covering the core wrapper and the core. The high temperature resistant fibers of the core are selected from the group consisting essentially of aramid fibers (Kevlar and Nomex), and polybenzimidazole fibers (PBI). The low temperature resistant fibers of the core wrapper and the outer sheath are either natural or synthetic fibers, such a cotton and polyester.

Abstract: The present friction spinning apparatus includes a draw frame section with an entrance trumpet including first and second fiber sliver guiding passageways for forming a three component corespun yarn. One of the guiding passageways directs a core roving into the draw frame section while the other sliver guiding passageway directs a core wrapper sliver into the draw frame section so that the core wrapper fibers surround the core fibers. Wrapping fibers are then wound about the core and core wrapper fibers in an elongated throat extending between a pair of rotating suction drums.

Abstract: The invention is a device which provides for separation of contaminants from a relatively high velocity stream of gas. The invention provides a first stage wherein the gas stream is decelerated and the contaminant particles are caused to separate from the air stream by interacting with a first surface. The interaction results in the particles to acquire a radial velocity vector and by virtue of the momentum of the contaminants particles. The contaminant particles are forced to the outer layer of the gas stream. The second stage of separation provides for further magnification of the radial velocity vector and also induces a slight tangential velocity component to the contaminant particle. By impacting the contaminants against a vane mounted within the gas stream, the contaminant particles, as a result of this impact, acquire a slight swirl or circular motion which causes the contaminant particles to be more localized.

Abstract: A fuel contamination monitor for separating particulate and liquid contaminants from a liquid fuel flowing through it has a liquid pervious housing enclosing layers of particulate matter separating filter media. A tubular liquid separating filter media is also disposed within the housing, and a liquid fuel outlet port through the wall of the housing communicates with the interior of the tubular liquid separating media. A shut-off valve is provided which interrupts the flow of liquid fuel through the filter unit in the event the media becomes too contaminated for effective contaminant separation.
