Breakaway devices for use in a meter-pit environment that protect connections between components of an AMR system are described herein. In various embodiments, at least one cable is adapted to operably couple a first AMR device and a second AMR device, wherein at least one of the first AMR device and the second AMR device is disposed in a utility meter pit. In an embodiment, at least once connector adapted to operably couple the cable to the first AMR device or the second AMR device is constructed to be decoupleabe in response to a force that is less than the linear breaking strength of the cable. In another embodiment, the cable may be constructed to have a length equal to at least about twice the distance between the first AMR device and the second AMR device. A coupling member is provided that secures a portion of the cable in a generally coiled configuration, and the coupling member is constructed to be decouplable to release a portion of the length of the cable in the generally coiled configuration in response to a force that is less than the linear breaking strength of the cable. The systems and devices disclosed herein act to prevent overstress on system components and connections when force is applied to the cable connecting these components.

A paper separation mechanism that requires no complicated design or manufacturing and prevents feeding of a plurality of sheets of paper simultaneously to assure sheet-by-sheet feeding of paper, and a paper feed apparatus using such a paper separation mechanism. In the paper feed apparatus, paper is fed sheet by sheet by cooperation of a paper feed roller and the paper separation mechanism which is abutted by the lower end of the paper stacked in an inclined state. The paper separation mechanism is provided with a plurality of projections which are abutted by the lower end of the paper and a plurality of arm portions holding the projections, respectively. Since each projection is not affected by the neighboring projection, load imposed by the paper on the each projection can be controlled independently by the corresponding arm portion.

A device that controls the engine speed of an internal combustion engine of a hand-held power tool has a protective control unit. The engine has an ignition control unit for controlling the ignition timing relative to a crank angle of a crankshaft based on the crankshaft speed and also has a centrifugal clutch driven by the crankshaft that begins to engage when a first engine speed is surpassed and is fully engaged when a second engine speed is reached. The protective control unit is activated within an engine speed range between the first and second engine speeds and monitors a dwell time of the actual engine speed within the engine speed range. When a predetermined dwell time of the actual engine speed is surpassed, the protective control unit intervenes in the combustion process and corrects the engine speed to a value that is outside of the engine speed range.

Methods and systems suitable for negotiating air traffic trajectory modification requests received from multiple aircraft that each has trajectory parameters. The methods include transmitting from at least a first aircraft a first trajectory modification request to alter the altitude, speed and / or lateral route thereof. A first conflict assessment is then performed to determine if the first trajectory modification request poses a conflict with the altitudes, speeds and lateral routes of other aircraft. If a conflict is not identified, the first trajectory modification request is granted and the first aircraft is notified of the first trajectory modification request being granted. Alternatively, if a conflict is identified, the first trajectory modification request is not granted and the first aircraft is notified thereof. If the first trajectory modification request was not granted, the first trajectory modification request is placed in a queue, which is periodically processed to perform subsequent conflict assessments.

The invention relates to a method for preparing cannabidiol through high-speed countercurrent chromatography separation and purification. The method comprises the following steps: alcohol extraction water sedimentation, macroporous resin adsorption and high-speed countercurrent chromatography separation. By combining a macroporous resin chromatographic column and a high-speed countercurrent chromatographic instrument and optimizing process parameters, high-purity cannabidiol is separated from flowers and leaves of industrial hemps, meanwhile, a psychotoxic component, namely tetrahydrocannabinol is removed, an adopted solvent is environment-friendly, is not remained, is low in cost and can be circularly utilized, so that the method is suitable for industrial production.

An installation method of panels includes a step of assembling panels by fitting projection parts 2, 3 of one panel 1 to insertion grooves 5, 6 of another panel 1, and a step of elastically attaching panels by applying an elastic tensioning force between assembled of panels. Also, a rail type fixing apparatus for installing panels includes a rail 20 having a guide groove 21 formed in a longitudinal direction thereof, and a plurality of attachment panels which are guided along guide groove 21 and are provided movably in the longitudinal direction of the rail 20 and in which a hook projections 32 are provided, and an elastic member which is provided between adjacent attachment panels and applies a tension restoring force between hook projections of the attachment panels to draw the hook projections 32 of the respective attachment panels 30 to each other.
