Abstract: An air induction system includes a hood inlet duct having a first induction inlet and an air induction plenum assembly having a second induction inlet. The air induction system also includes an air box in fluid communication with the air induction plenum and the hood inlet duct. The air box defines an inner box cavity. The air induction system also includes a panel filter disposed inside the air box, wherein the panel filter divides the inner box cavity so that the first induction inlet and the second induction inlet are upstream of the panel filter.

Abstract: A system for controlling an aerodynamic shutter of a vehicle includes an ambient temperature estimation module that determines an ambient temperature. A shutter control module that determines whether to actuate the shutter based on the ambient temperature. The shutter control module also determines a predetermined period before selectively applying a predetermined torque value to the shutter. The predetermined period is selected based on the ambient temperature.

Abstract: A system and a method for conducting research including a plurality of participants includes receiving, from a first client application associated with a first research participant, a first type of content including a status of the first research participant with respect to a first target location; selecting a second type of content based at least in part on the first type of content received from the first client application; determining to transmit the second type of content to at least one of the first client application and a second client application associated with a research organizer based at least in part on the first type of content received from the first client application; and transmitting the second type of content to at least one of the first client application and the second client application.

Abstract: In a process for oligomerizing a C2 to C6 n-olefin feedstock over surface deactivated ZSM-23, the feedstock contains from about 0.1 wt % to about 25 wt % of an iso-olefin and the C12+ fraction of the oligomerized olefin product contains less than 0.5 atom % of quaternary carbon atoms.

Abstract: A rack support assembly for an ATV for a rack and shock assembly that is removably attachable to a hitch and rack posts of an all terrain vehicle. The assembly comprises an upper bar and a lower bar. A pair of shock absorbers is coupled to and extends between the upper and lower bars so that the upper and lower bars are orientated parallel to each other. A coupler removably attaches the lower bar to the hitch so that the lower bar is horizontally orientated. Each of a pair of supports is attached to the upper bar. The supports are each removably attachable to one of the rack posts.

Abstract: Processes are disclosed for making black powder and black powder substitutes without requiring binder-effective amounts of a binder and lacquers.

Abstract: A process for reproducibly forming a thermally and oxidatively stable high hydroxyl glycerol di-ester compound which is particularly useful as a lubricant. The glycerol di-ester compound is formed by reacting a glycidyl ester with an excess of a neo acid salt. The di-ester product is produced in a nearly quantitative conversion and is readily recoverable from the reaction mixture via a water wash, vacuum dry, and a mild wiped film evaporator treatment.

Abstract: A pair of EPS foam panels have laterally aligned holes arranged in a rectangular grid. Cross wires or rods extend through the holes. Longitudinally extending wires or rods are located against the interior surfaces of the walls and are welded to the cross rods. Retaining means on the ends of the cross rods are disposed against the exterior surfaces of the walls to provide a sandwich construction firmly to interconnect the walls and the rods.

Abstract: A continuous process of manufacturing black powder and black powder substitute using a twin screw extruder is disclosed. Guar gum mixed with the composition at a concentration in the range from 0.05% to 0.5%, by weight, dramatically reduced the friction in the dies and permitted extrusion of the powder at much lower water levels. Different size dies used in combination with face cutting of the extruded strands produce various sized granules. The process can be operated remotely and automatically. The process reduces the number of buildings, equipment and personnel required to manufacture black powder or black powder substitute. The process produces more uniform and reproducible particle sizes.

Abstract: Infrared illuminant compositions are disclosed which produce significant quantities of infrared radiation when burned but which produce very little visible light. The infrared illuminant compositions provide specific illumination in the spectral range visible with night vision devices. The disclosed infrared illuminant compositions include ammonium nitrate as the main oxidizer, an infrared generator such as cesium nitrate, rubidium nitrate, or mixtures thereof, and a fuel. By eliminating potassium and its direct and indirect visible light contributions, from the illuminant compositions, improved concealment indexes are obtained. Other additives, including conventional binders and burn rate modifiers may be used as to tailor the performance and physical characteristics of the infrared illuminant composition.

Abstract: Energetic materials are continuously processed in a twin-screw extruder to provide safe, low-cost, high quality manufacturing of pyrotechnic compositions, gun propellants, and high explosives. The energetic materials are processed by first lacquering the binder and other soluble ingredients in a solvent. The lacquer solution is introduced into a twin-screw extruder. At least one solid reactive material ingredient, such as metal and/or oxidizer particles, is also introduced into the twin-screw extruder. The solid reactive material ingredient and the lacquer solution are mixed within the twin-screw extruder. After mixing, sufficient solvent is removed by heating or by vacuum to permit bulk granulation of the energetic material. Moist energetic material is then granulated using a remote continuous rotary granulator. The energetic material is dried to produce free-flowing granules which may be used as feedstock for further processing.

Abstract: A process forms decoy flare pellets which satisfy predetermined burn requirements without milling additional grooves into the pellet flare material after that material is consolidated. The process includes providing sufficient surface area to the flare material during consolidation to eliminate the need for milling. Consolidated flare pellets are then coated with an ignition composition and installed in a decoy flare housing.

Abstract: A continuous extrusion process for manufacturing composite gun propellant is disclosed. The disclosed process is particularly suitable for preparing gun propellant formulations based upon a cellulose ester binder. In the process, the binder ingredients are dissolved in an organic solvent and then pumped directly into a twin-screw extruder. The other ingredients, except the oxidizer, may optionally be dissolved in the organic solvent prior to introduction into the twin-screw extruder. The oxidizer is dried, ground, and also fed dry to the twin-screw extruder. In the extruder, the materials are thoroughly mixed and the solvent is reduced to sufficient level for direct extrusion through the desired dies.

Abstract: A low pass filter for use in an image band pass filter of a photoelectron spectromicroscope incorporating a virtual potential surface for reflecting electrons below a particular energy and a special charged particle trap or super dump for unwanted electrons. The filter construction with the super dump reduces the proportion of elastically and inelastically scattered high energy electron escaping the filter.
