A lightweight gas spring with a volume compensator, which is incorporated into a fork leg of a two-wheel vehicle fork. The fork leg includes a housing having an upper inner telescoping hollow rod with a closed top and bottom end which is partially inserted into a lower outer telescoping rod having a closed bottom end. The inner upper telescoping rod inside includes a stationary volume compensator, a reciprocating piston, a first expandable and contractible gas chamber between the volume compensator and the piston which functions as a positive gas spring, and a second expandable and contractible gas chamber between the piston and the bottom end which can function as a negative gas spring, an air bypass channel which is longitudinally positioned on the inner surface of the inner telescoping rod may open to the first and second gas chamber.

An adjustable coil spring system placed within a leg of a vehicle such as a mountain bicycle fork. The spring system comprises an adjustable first soft spring seated on top of a second firm spring having greater length than the first soft spring. A coupler assembly is positioned between two springs comprised of a threaded bolt threadedly received within a coupler. A spring adjustment mechanism may comprise a knob connected to the threaded bolt through a non-round shaped shaft, wherein the threaded bolt is disposed within the first soft spring. As the knob rotates, the coupler is moved up along the threaded bolt, decreasing the length of the first soft spring, thereby increasing firm spring characteristics of the spring system. As the knob rotates in an opposite direction, the coupler moves down, increasing the length of the first soft spring, thereby increasing soft spring characteristics of the spring system.

A molded assembly for a unique combination of a steering tube and crown for use in a two vehicle fork such as a bicycle fork, wherein the steering tube transversely connects to the crown at the crown's center position. The crown is further connected to the fork leg housings. The steering tube is comprised of a bottom neck portion and a main round body portion, wherein the bottom neck is varies in shape from a round to non-round exterior which is used to eliminate rotation when the tube is molded into the crown. The interior of the crown at the location where it is molded into the steering tube is also formed in a matching non-round shape. The steering tube is chemically made of uncured resin blended with carbon fiber composites, which can be cured under heat after the assembly is molded.

The present invention relates to a bicycle fork comprising an improved axle with non-round tapered ends affixed into dropouts with openings to match the axle ends through a taper-lock affixation for improving the torsional strength of the fork and facilitate ease of the axle installation. The improved axle consists of a first non-round end with interior female threads connecting an intermediate cylindrical portion which connects to a second non-round tapered end. An improved tapered split non-round nut having a cylindrical bolt possessing male threads lock the nut to the first end of the axle, wherein said bolt has an another preferred embodiment which connects a rotatable handle for ease of the axle installation.

A method and apparatus for producing molecular oxygen in the excited singlet delta oxygen electronic state for use as an excited species reactant in a chemical laser. Flowtubes defined by permeable membranes are used to mix the gas and liquid phase reactants to generate singlet delta oxygen and also to separate the generated singlet delta oxygen from the liquid phase products and reactants thereby eliminating liquid reactant carryover.
