Abstract:
A flying driving vehicle, comprising a body; a driving interface coupled to the body, configured to enable the body to drive on a surface and one or more driving actuators configured to provide power to the driving interface; a set of propellers coupled to the body; wherein the propellers' movement keep the vehicle in place when the surface is in slope; a controller for controlling the speed of the driving interface, a rotation speed of the set of propellers and a magnitude and direction of thrust applied by the set of propellers
Abstract:
Improved function of floor stripping machines is achieved by orienting the leading edge of a blade attached to the machine at an angle that is other than perpendicular to the direction of travel of the machine. Additional benefits result from making the angle of the blade's leading edge adjustable.
Abstract:
A floor stripping machine for removing floor covering from a floor surface includes a base, a motor secured to the base, a rear wheel arrangement driven by the motor, and a blade assembly. The blade assembly is secured to a remaining portion of the machine and has a removable clamp with a cutter. The machine has a forward downward sloping angle, a low center of gravity, and is obstruction free for mounting by an operator. The blade assembly may include a dovetail for a variety of tool heads. One example of a blade has a base flange, a pair of side flanges with forward leaning angles, and a hook in between each side flange and the base flange.
Abstract:
Die Erfindung betrifft eine Seildurchlaufwinde mit einer Antriebseinheit (10) und einer Abtriebseinheit (60) zum Beaufschlagen eines Seils mit einer Antriebskraft, welche mit der Antriebseinheit (20) gekoppelt ist. Erfindungsgemäß wird vorgeschlagen, das die Antriebseinheit (20) einen Frequenzumrichter (30) mit einer Primärseite (32) zur Stromaufnahme aus einem Versorgungsnetz (33) und eine Sekundärseite (36) zur Abgabe einer Wechselspannung (U U , U V , U W ), einen Wechselstrommotor (40) zum Antreiben der Seildurchlaufwinde (10) mit variabler Drehzahl (ω 1 ), der durch den Frequenzumrichter (30) mit der Wechselspannung ((U U , U V , U W ) versorgt wird, eine Steuereinheit (50), die zum Steuern der Antriebseinheit (20) mit dem Frequenzumrichter (30) und dem Wechselstrommotor (40) verschaltet ist, wobei die Steuereinheit (50) dazu eingerichtet ist, die Drehzahl (ω 1 ) des Wechselstrommotors (40) mittels des Frequenzumrichters (30) zu ändern, aufweist.
Abstract:
of the Disclosure The present disclosure provides systems and methods for shaping the load of a building for more efficient sizing and/or economics of an energy storage and/or microgrid system. Shaping the load of a building can include identifying a plurality of core hours of a time period increasing a load of the building, a plurality of different increase instances, by interfacing with a BAS and an ESS during the plurality of core hours, and decreasing the load of the building, a plurality of different decrease instances, by interfacing with the BAS and the ESS during the plurality of core hours, wherein each increase instance from the plurality of different increase instances of the load profile is followed by a decrease instance from the plurality of decrease instances of the load profile.
Abstract:
To provide a motorized cleaning apparatus (20), that is manually effective in adjusting the horizontal destance of a rotatable brush (21) from a facade according to its variable protrusions details. On each of the the right and left hands of a worker supporting chair, rails (24) are installed, supporting from the back balance blocks, and supporting from their top sides two slideable beams (26), holding a motor housing, which is linked from its front side to an intermediate shaft (30) via a supporting frame (31), a belt installed on a drive gear from the motor side drives the intermediate shaft (30), which is driving via its end gears the brush's shaft (39), using two toothed belts. To support the brush (21), its shaft is linked from its both ends to the intermediate shaft (30) through a two U-shaped joints (40), which are inserted inside the ends of the intermediate shaft (30) and the brush's shaft (39), wherein carrier bearings are installed in-between them.
