摘要:
A cushioning device that imparts both stability and cushioning to the midsole of an athletic shoe. The cushioning device includes a bladder that has a plurality of separate fluid chambers positioned around a perimeter. The chambers define an open central portion of the bladder arrangement. Each of the chambers has an inner side, an outer side and a height that increases from a minimum adjacent the inner side to a maximum toward the outer side thereof.

A support structure for a shoe includes a bladder arrangement having at least one (and preferably two) fluid-filled chamber arranged in a heel region of the sole of the shoe. The fluid-filled chamber has outer walls with a pressurized fluid disposed therein. The fluid-filled chamber is configured to be compressively deformed when an external pressure is applied thereto, such as the pressure exerted by a wearer's foot. The support structure also includes at least one pillar disposed in the fluid-filled chamber. The pillars are configured to decrease the amount by which the fluid-filled chamber is compressively deformed when the external pressure is applied thereto, while still permitting the fluid-filled chambers to be deformed sufficiently to provide-adequate protection against the force of impact during use.
摘要:
The present invention generally relates to a beam suitable for providing support to, for example, an automobile body. More specifically, the present invention relates to a steel boxed I-beam structure having compound curves, formed without use of a dedicated fixture or jig. Typically, the steel boxed I-beam structure provides a strong support that can be manufactured with a minimum of effort, and without the use of heavier shop machinery.

Improved stabilized spinel battery cathode material and methods of treating particles of spinel battery cathode material to produce a protective coating of battery-inactive lithium metal oxide on the particles are provided. The methods basically comprise mixing the spinel particles with a particulate reactant selected from a lithium salt, a lithium metal oxide or a mixture of a lithium salt and a metal oxide and then heating the resultant particulate mixture for a time and temperature to react the particulate reactant with the spinel particles whereby a protective coating of lithium metal oxide is formed on the spinel particles and the lithium content of the spinel adjacent to the coating is increased a limited amount.

An improved scuba weight having a hex-nut locking device molded into the weight is described. The hex-nut locking device secures the weight to a diver's belt, but can be easily loosened, permitting the casting off of the weight, including in underwater operations, if desired.

Halogenated contaminants are removed from soil by reaction schemes which are carried out in a slurry of the soil and a reagent mixture. The latter is made up of an alkaline constituent--an alkali metal hydroxide, an alkali metal hydroxide/alcohol or alkali metal hydroxide/glycol mixture, or an alkoxide--and a sulfoxide catalyst.

A picosecond pulse generator for producing pulses having widths in the or of 10.sup.-12 seconds utilizes a Josephson junction that has an external load resistor connected in shunt therewith by a balanced transmission line. The Josephson junction is driven by a high frequency oscillator, and the AC current, I.sub.1, flowing through it is adapted to have its amplitude varied with respect to I.sub.c, the critical current of the junction. As the value of I.sub.1 /I.sub.c exceeds one and increases, first a single and then an increasing number of picosecond pulses are produced during each half cycle of the high frequency oscillator.

A regional aircraft boarding module can be provided at an airport concourse in place of or in addition to a conventional large aircraft boarding bridge. The regional aircraft boarding module includes regional aircraft rotunda between a number of secondary passenger bridges that are coupled to the regional aircraft rotunda. A method of using the regional aircraft boarding module includes an activity selected from docking a regional aircraft thereto, interfacing a large aircraft boarding bridge thereto, and combinations thereof.
摘要:
A regional aircraft boarding pier can be provided at an airport concourse in place of one or two conventional large aircraft boarding bridges. The regional aircraft boarding pier includes a primary passenger bridge between the airport concourse and a hub. A number of secondary passenger bridges extend from the hub to individual regional aircraft. In this way, an equivalent number of passenger seats can be serviced as between large and regional aircraft, and large and regional aircraft can be docked at a common airport terminal. Consequently, passengers can more efficiently and conveniently transfer between connecting flights that are on both large and regional aircraft. The hub of the boarding pier can take a number of configurations to optimally use the space available. The hub can also support large aircraft boarding bridges as well as the secondary passenger bridges docked to smaller, regional aircraft.
