摘要:
An aligning device that can be mounted to a conduit for rotating the conduit in successive angular intervals. The aligning device having a bracket that can be secured to the conduit. The bracket having four bubble levels at its periphery equally spaced from each other. Each bubble level can be horizontally leveled.

An aimed or aiming firearm can be detected before it is able to shoot. Wideband radar signals can be used to identify the barrel of a firearm when the radar antenna and barrel are aiming at or near each other. Signal processing correlates reflected signals to the characteristics of specific firearms of interest, and alerts the user when someone is pointing such a firearm at them. Modern wideband radar systems with fast signal processing speed can enable real-time detection of firearm threats in crowded and cluttered areas before they shoot, which has never before been possible. Related systems, apparatus, methods, and articles are also described.

A directing apparatus includes a mechanism for producing steerable energy. The apparatus includes a mechanism for steering energy from the producing mechanism while the producing mechanism is stationary. The steering mechanism is in communication with the producing mechanism. The steering mechanism includes a scanning mechanism which continuously in a first direction scans the volume of a surrounding vertically and horizontally. A directing method.
摘要:
An aqueous based electrically conductive paint having substantially enhanced electrical properties employing a nickel pigment and a surfactant having substantial unsaturation characteristics. Paint is held at 50.degree. C. or greater for at least one hour requires no aging before use. The paint finds particular application in providing EMI and RFI shielding for electrical components when applied to cabinetry housing such components.
摘要:
A rotating screen, for use with a centrifugal fan of an engine, includes a hub having a rotational axis and a plurality of blades extending radially outwardly from the hub. Each of the blades includes a root adjacent the hub, a tip, a leading edge extending between the root and the tip, and a trailing edge extending between the root and the tip. The blades also include an airfoil shape. The rotating screen also includes a band concentric with the hub and interconnecting the tips of the respective blades.

摘要:
A powered coupling system is configured to interconnect utility lines such as fluid and/or electric lines of a vehicle tractor to a trailer. A curved track is mounted to a frame of the tractor, and the system includes pneumatic and/or electrical connectors that move along the curved track to align the connectors with a corresponding connectors on a trailer. A linear actuator causes the connectors on the tractor to shift vertically to connect and disconnect the connectors on the tractor to connectors on the trailer. The curved track permits alignment of the connectors on the tractor with the connectors on the trailer even if the trailer is not in a straight line with the tractor.
摘要:
A wheeled upright luggage case having oversized wheels for improved rolling movement. The luggage case has a pair of wheels that are oversize in proportion to the body of the case. The oversize wheels are rotatably mounted in fender assemblies disposed on the outsides of the body of the case, so that the oversize wheels do not detract from the cargo capacity of the case. The wheels are mounted to protrude a specified relational distance from the bottom, or the back and the bottom, of the case to permit the case to be rolled while tilted at a wide variety of angles and to easily be pulled up stairs or curbs.
