US Patent:

6680099, Jan 20, 2004

Filed:

Jan 21, 1997

Appl. No.:

08/787512

Inventors:

John C. Brewer - Norfolk MA

Assignee:

The United States of America as represented by the Secretary of Transportation - Washington DC

International Classification:

B32B 326

US Classification:

428 63, 428 58, 428458, 428465, 156 94

Abstract:

A means and method of enhancing the damage tolerance of adhesive bonds by introducing gaps in the adhesive to divide the adhesive layer into discrete regions. The gaps are created by placing strips of barrier material between the two adherends before the adhesive is put in place and cured. If the two adherends begin to debond along the interface between one of the adherends and the adhesive, the gap arrests the debonding process.

Southworth, Incorporated - Portland ME

International Classification:

B60P 102

US Classification:

414608

Abstract:

A system for allowing a wheeled truck to be rolled on and off a vertically extendable lift table assembly, whereby material handling operations between one vertical elevation, and one horizontal location, and the second vertical location, at a second horizontal location, will be facilitated. The roll-away lifting combination herein essentially comprises a vertically extendable lift table assembly with a cooperating wheeled truck assembly that can be selectively superposed, i. e. , moved on or off, a lift table assembly which in turn allows the entire assembly to be conveniently moved from one horizontal location to another. The lift table itself preferably has a double scissor-jack linkwork, which allows the wheeled truck to be raised, for example, to heights of approximately seven feet above a horizontal ground reference. The improved roll-away combination taught herein comprises a particular form of mating between at least one horizontally and longitudinally disposed flange and guideway, on the lift table, and an engaging wheel contact means, on the wheeled truck. The present invention teaches a manner of allowing such a modified wheeled truck to be easily positioned upon said lift table, elevated to any vertical level, or moved to any horizontal location.

International Classification:

B64D 1702

US Classification:

244145

Abstract:

A gliding decelerator and an assembly for use therein for improving the l to drag ratio associated therewith. In a preferred embodiment, the gliding decelerator includes a ram-air canopy shaped to include a plurality of half-cells, each half-cell having an open leading end and a closed tailing end. Inflatable bladders are secured within the respective half-cells of the canopy, the inflatable bladders being appropriately dimensioned so that, when inflated soon after the canopy has been opened, each bladder fills its respective half-cell in such a way as to stiffen the half-cell both along its length and at its open leading end. The inflatable bladders may be inflated simultaneously or in stages, the inflation means comprising a gas source, a flexible manifold connecting the gas source to the half-cells and valve means for controlling the output of the gas source. Control of the valve means may be automatic, e. g. , a timer, a remote control unit, or may be controlled by a parachutist, e. g.

International Classification:

B60P 100

US Classification:

254 9C

Abstract:

A system for allowing a wheeled truck to cooperate with a relatively stationary lift table assembly, in order to selectively raise the truck during various material handling operations. The lifting combination essentially comprises a vertically extendable lift table assembly which cooperates with a wheeled truck which can be selectively superposed upon the lift table assembly. The lift table includes a scissor jack linkwork, and can be easily positioned, as necessary, within a material handling space. The wheeled truck includes means to engage guideways on the lift table assembly, as the truck is wheeled thereover to its selective engagement position.
