摘要:
This invention relates to nanoscale molecule synthesis, including three-dimensional addressable arrays of biopolymeric nucleic acids and processes for manufacturing such arrays. Such arrays can be functionalized with complementary chemical reactive probes to provide catalytic enzymes.

The present invention is directed to the use of artificial polymers in the mimetization of enzymatic active sites and the carrying-out of catalysis using these artificial enzymes. Further, as used herein, an artificial enzyme refers more generally to a polymer-based scaffold for presenting specific chemically active atoms optimally for reactions, not just those that mimic natural enzymes. Various polymers can be used for this mimetization, including polyimides, polyurea, polyurethane, polyacrylic acid, and polylactic acid, as well as other polymers having properties and functionality that enable integration with natural and artificial amino acids, other molecules having nucleophilic and electrophilic groups (akin to the amine and carboxyl functionalities, respectively, of amino acids), as well as other molecules contributing unique chemical abilities not usually associated with the orthogonal functions inherent in most amino acids, i.e., amines, carboxyls, formamides, hydroxyls, mercaptyls and saturated hydrocarbons.

A steering system for a vehicle having a body supported on at least two sets of steerable wheels, generally consisting of a steering shaft provided with a wheel, supported on such body; a torque transmitting main shaft supported longitudinally on the body; means operatively interconnecting the steering shaft and the main shaft for transmitting rotary motion of the steering shaft to rotary motion of the main shaft; a first transversely displaceable means operatively interconnecting knuckle brackets of one of the sets of steerable wheels; a steering gear directly operatively interconnecting the main shaft and the first transversely displaceable means for translating rotary motion of the main shaft to linear motion of the first transversely displaceable means; second transversely displaceable means operatively interconnecting knuckle brackets of the other of the sets of steerable wheels; and a steering gear directly operatively interconnecting the main shaft and the second transversely displaceable means for translating rotary motion of the main shaft to linear motion of the second transversely displaceable means.

Adjustable seats and components thereof are detailed. The seats, particularly (although not exclusively) useful in commercial aircraft, permit substantial angular recline without the corresponding rearward linear movement necessarily occurring in conventional seats. The seats additionally may have discontinuous, or non-integral, seat bottoms, with the heights of the forward portions of the bottoms being adjustable mechanically. Tray tables optionally associated with the seats further omit any central slot and may define one or more pivot axes in locations different than exist in conventional seats.

A wheel suspension system for a vehicle having a body supported on a set of wheels each provided with a rim and an axle generally consisting of a lower control arm pivotally connectable to a first portion of such body; an upper control arm pivotally connectable to a second portion of such body; a roller bearing having inner and outer races, disposed within such rim, coaxially relative to the rotational axis of the rim; a steering knuckle mounted on the outer race of the bearing, having a first portion pivotally connected to the lower control arm and a second portion pivotally connected to the upper control arm, defining a steering axis intersecting the rotational axis of the rim; and a hub member mounted on the inner race and connectable to an axle receivable through an opening provided in the steering knuckle.

摘要:
Described are passenger seats comprising a seat back support and a neck support structure comprising a headrest coupled to the seat back support and at least one wing pivotally coupled to the headrest, wherein the at least one wing is configured to rotate downwardly from a stowed position to a first deployed position and the at least one wing is also configured to rotate laterally from the stowed position to a second deployed position. The neck support structure may comprise a first wing and a second wing. A cover may be removably coupled to the at least one wing. The at least one wing may be formed from a flexible material.

摘要:
Seating arrangements for passenger aircraft or other vehicles are detailed. Some arrangements position seats at offsets from a longitudinal axis of a vehicle cabin in either “V” shapes or herringbone patterns. Other arrangements include seats that are staggered within the cabin. Further arrangements include pairs of seat that are both parallel and offset from the longitudinal axis, but are placed so that feet of the port and starboard passengers point away from the fuselage. All embodiments contemplate providing seats that are convertible to beds, although this conversion is not required.
