Abstract:
In the present invention, a hydroentangled and three-dimensionally patterned fibrous material is formed from a fibrous matrix to produce a nonwoven fabric of pronounced open area and enhanced physical properties, including abrasive, and particularly wet abrasive, performance. A three-dimensional pattern utilized on the forming surface results in the nonwoven fabric having a diaphanous gauze-like or cheesecloth-like presentation. A method of making a nonwoven material embodying the principles of the present invention contemplates the use of staple length fibers to facilitate economical fabric formation. Formation of the fibrous nonwoven fabric on a three-dimensional, image transfer device by hydroentangling imparts desired physical properties to the fabric such as the controlled placement of the fiber population relative to the desired three-dimensional pattern of the imaging device. This nonwoven fabric may be natural or colored.
Abstract:
Presented is a method of conformally coating a light emitting semiconductor structure with a phosphor layer to produce a substantially uniform white light. A light emitting semiconductor structure is coupled to a submount, a first bias voltage is applied to the submount, and a second bias voltage is applied to a solution of charged phosphor particles. The charged phosphor particles deposit on the conductive surfaces of the light emitting semiconductor structure. If the light emitting semiconductor structure includes a nonconductive substrate, the light emitting semiconductor structure is coated with an electroconductive material to induce phosphor deposition. The electrophoretic deposition of the phosphor particles creates a phosphor layer of uniform thickness that produces uniform white light without colored rings.
Abstract:
A vehicle seat assembly includes a seat back and a seat bottom and is attached to a vehicle support structure by a mounting assembly. The mounting assembly includes a first track and a second track supported for movement relative to the first track along a first longitudinal axis. The seat bottom is supported on the second track for axial movement with the second track. This allows the seat assembly to be adjusted forwardly or rearwardly by a seat occupant. The seat back can also be moved relative to the second track between an upright position and a recliner position. The seat assembly receives a seat load resulting from the seat occupant sitting in the seat with the seat back in the reclined position and/or from a forward movement of the seat occupant during a deceleration of the vehicle when the seat occupant is belted into the seat. The mounting assembly includes at least one bracket supported on the second track for movement therewith and a reinforcement member that is fixed to the bracket and defines a second longitudinal axis, which is parallel to said first longitudinal axis. The reinforcement member distributes the seat load applied to the bracket along the length of the second track.
Abstract:
The present invention relates to a method of producing liposomes useful for encapsulating and delivering a wide variety of biologically active materials. The invention provides liposomes and a production method which is simple, feasible and inexpensive for the large-scale commercial manufacturing of liposomes and encapsulated materials. The method involves the formation of a liposome dispersion in the absence of an organic solvent or detergent, one or several cycles of freezing and thawing the liposomes, and dehydration of the liposome dispersion to form a lipid powder. When desired, the lipid powder is hydrated in the presence of the biologically active material whereby the material is encapsulated in reconstituted liposomes. The method can also include combining the liposome dispersion with a bulking agent prior to the dehydration and formation of the lipid powder. The addition of the bulking agent facilitates the handling of the lipid powder as well as its rapid dispersal upon hydration.
Abstract:
An LED component is provided, with light emission in the green-to-near UV wavelength range. The light-emitting semiconductor die is encapsulated with one or more silicone compounds, including a hard outer shell, an interior gel or resilient layer, or both. The silicone material is stable over temperature and humidity ranges, and over exposure to ambient UV radiation. As a consequence, the LED component has an advantageously long lifetime, in which it is free of “yellowing” attenuation which would reduce the green-to-near UV light output.
Abstract:
The present invention relates generally to a fastener used for connecting a first link member to a second link member in a linkage assembly. The second link member includes a pair of aligned apertures and a slot located transversely between the apertures. The first link member includes an aperture at a first end that is designed to be received in the slot located in the second link member. The fastener has a centering post at a distal end and a head portion at a proximal end with a self-tapping portion located between the head portion and the centering post. The aperture in the first link member is aligned with the apertures in the second link member and the fastener is inserted through the apertures until the self-tapping portion contacts the first link member. Thereafter, rotation of the fastener in a first direction taps the self-tapping portion of the fastener through the aperture in the first link member. The fastener is rotated until the first link member is flush against the head portion of the fastener. Thus, the fastener rotatably secures the first link member to the second link member and prevents lateral free play movement between the fastener and the second link member, and between the first link member and the second link member.
Abstract:
The invention relates to stable compositions of proteins and related methods wherein a protein capable of transitioning into the molten globular state is contacted with a negatively charged lipid vesicle, thereby stabilizing the protein against thermally-induced aggregation, denaturation, and loss of activity. The protein:phospholipid complex directly stabilizes the secondary and tertiary structure of the protein, and the compositions are useful in high temperature formulations and in novel delivery vehicles.

Abstract:
An amusement ride is provided, of the type that moves and tilts passengers viewing a motion picture, which is more versatile than prior rides. A plurality of passenger-holding frames is provided, that are all moved in synchronism, each by a separate set of actuators, while the passengers view a stationary screen. The passenger-holding frame is pivoted up and down on a beam which is supported by only two largely vertical actuators, while two pairs of links or arms limit movement of the beam.
