Abstract: A pallet return assembly includes at least one support member, a bracket member, a base member including a stopper member, and a lever that, when actuated, moves the base member and its stopper member from a pallet catch position to a pallet release position. In the pallet catch position, the stopper member catches a bottom of a pallet positioned on the roller tracks of the pallet bay and restricts the pallet from moving along the roller tracks. In the pallet release position, the stopper member no longer catches the bottom of the pallet positioned on the roller tracks and no longer restricts the pallet from moving along the roller tracks.

Abstract: A system for actively controlling the span-wise rotational twist of a hollow beam along its longitudinal axis, including a hollow beam structure having a leading edge and a trailing edge region, the beam being split along its length, an actuator arranged between split surfaces of the beam, the actuator adapted to move the split surfaces in a longitudinal direction relative to each other, inducing a twist in the beam. The hollow beam is affixed to an external structure at one or both ends, with only the zero warping displacement points of the beam being attached to the external structure, material or device. In one embodiment, the actuator is a plurality of solid blocks with high thermal expansion coefficients arranged between frames of the split surfaces of the beam, with alternating blocks being heated by resistance heaters to cause expansion in the spanwise longitudinal direction.

Abstract: The present invention provides compositions and methods for protecting cells and tissues from damage associated with therapeutic treatments of cancers and other diseases and conditions where reactive oxygen species are produced. The present invention also provides compositions useful as research reagents.

Abstract: A vehicle including at least one bladder for containing a two-phase liquid-gas fuel at a predetermined pressure, with a bladder outlet arranged to releasing vapor fuel from the bladder. The fuel provides energy for propulsion of the vehicle, and the vapor pressure of the fuel provides initial structural integrity of the vehicle, by rigidizing and stiffening the beam assembly to resist inward buckling until the liquid fuel is expended. In an exemplary embodiment, the vehicle is an unmanned aerial vehicle. A combustion chamber and thermoelectric conversion module can generate electricity for a propeller and battery.

Abstract: A vehicle including at least one bladder for containing a fuel as liquid and gas at a predetermined pressure, with a bladder outlet arranged to releasing fuel from the bladder and to maintain the fuel in the bladder at the predetermined pressure, the fuel provides thrust to the vehicle upon combustion, the fuel-filled bladder providing initial structural integrity of the vehicle. In an exemplary embodiment, the vehicle is an unmanned anal vehicle. A combustion chamber and thermoelectric conversion module can generate electricity for a propellor and battery from the fuel supply. Internal vapor pressure is maintained until the fuel bladder is empty.

Abstract: The present invention provides methods, compositions and kits for identifying molecules such as proteins or nucleic acids that are found in proximity to each other in vitro or in vivo. For example, the present invention provides for the modification of one or more molecules that are complexed with, or in proximity to, a target biomolecule, wherein the modification of the one or more complexed or proximal molecules is detected.

Abstract: A sun guard for a vehicle may be constructed with a darkly tinted transparent acrylic shield to enable a vehicle occupant to comfortably view objects such as a traffic light even while the sun is within nearly the same line of vision, eliminating blinding glare by inhibiting the direct transmission of sunlight to a substantially uniform average of about two to three percent across the visible spectrum. A lighter tinted shield may alternatively be provided with a dark window film covering a major surface of the shield to provide similar visible light transmission characteristics. A clip having at least one double clamp spring pivotally attaches the sun guard to an existing opaque sun visor.

Abstract: An extendable automobile sun glare shield may be constructed with a body of opaque material with a shield of polaraized material having a film of black glass covering the upper section of the shield slidably disposed to extend and retract from a cavity disposed within the body of opaque material.

Abstract: A process for separating suspended clay and sand solids from the slimes of phosphate tailings is described. The suspended solids are rapidly agglomerated and a relatively dense sludge which settles to the bottom of the separation vessel is formed. The sludge may then be discharged into settling ponds for dewatering and compaction.
