Contaminants are removed from raw water or discharge water from plants, such as sewerage and industrial plants, by applying direct current through an array of spaced, alternately charged electrodes to eliminate or minimize clogging of the electrodes with precipitated contaminants. Polarity may be switched periodically to assist in eliminating or minimizing clogging. In illustrated embodiments, electrode arrays are contained in housings of dielectric material to form modules, To increase processing capacity, the modules are arranged in parallel arrays. Alternatively, a single module is scaled up for large or industrial applications or scaled down for personal use. Instead of housing the electrode arrays in modules through which liquid passes, the electrode arrays for some batch applications are dipped in the water or aqueous solutions.

A method for displaying thumbnails on a mobile device includes allocating at least two buffers in a storage system of the mobile device, where the at least two buffers comprise a displayed thumbnail buffer and a current thumbnail buffer. Indices of the thumbnails on are displayed on a display screen of the mobile device, and thumbnails from the displayed thumbnail buffer are read if the thumbnails correspond to the indices are found in the displayed thumbnail buffer. In addition, the method further includes reading the thumbnails from the current thumbnail and displaying the thumbnails on the display screen of the mobile device.

Systems, devices, and methods are provided for the transmission of power in motor vehicles. Power can be transmitted in a smoother and more efficient manner, with smaller and even less mechanical components, by splitting torque into two or more torque paths. A power transmission apparatus comprises a power input shaft, a planetary gear set coupled to the power input shaft, and a variator, such as a continuously variable transmission (CVT), coupled to the gear set. The various components of the planetary gear set and the variator are arranged such that torque is split between two or more torque paths and then recombined before power is output to a gear box and a differential of the motor vehicle.

Disclosed herein are power transmissions having one or more operational modes, for example, a continuously variable transmission (CVT) mode, an infinitely variable transmission (IVT) mode, and an IVT/CVT mode, that can be selected for by engaging different clutches and brakes. Disclosed herein are power transmissions comprising a power input shaft, one or more planetary gear sets, a variator (such as a CVT), and one or more clutches and brakes. In some embodiments, a first brake selects an IVT mode, a second brake selects a CVT mode, and a third brake selects an IVT/CVT mode.

The invention discloses an electric multifunctional high-efficiency garden maintenance device, which comprises an underframe, a water storage tank and a garbage can, wherein a rear wheel is arranged at the right lower end of the underframe; a drive motor is arranged at the left side of the rear wheel; a driving wheel is arranged at the left side of the drive motor; a driving belt is connected between the drive motor and the driving wheel; a control frame is arranged at the right end of the underframe; and a control box is arranged at the right side of the control frame. The electric multifunctional high-efficiency garden maintenance device is mainly used for garden maintenance work; the control box is used for controlling a fan to work, leaves on the ground and broken weeds are sucked into the garbage can through a suction cup, the height of the suction cup can be adjusted through a fixed device and a lifting pipe and different heights can be adjusted according to different leaves, so that smooth and efficient maintenance work is facilitated; meanwhile, the device also has a spraying function; and a water receiving pipe is arranged at a water outlet and trees in the garden can be irrigated, so that the functionality of the device is improved and more practical choices are provided for development of the garden maintenance work.

The invention discloses a large-area concrete ground high-flatness construction device and a construction method thereof. The large-area concrete ground high-flatness construction device comprises twoside supporting rods, an end supporting rod, a top connecting table, two sleeving clamping frames, a frame plate, a leveling seat and a flat pressing table, the two side supporting rods are parallelly arranged, and lower supporting rods are vertically arranged on the lower parts of the two ends of the two side supporting rods correspondingly. The large-area concrete ground high-flatness construction device has the beneficial effects that a first hydraulic oil cylinder drives hammer pressing plates through first hydraulic columns to quickly extend and move downwards to conduct hammer pressingand leveling on a protruding part, so that the flatness of the concrete ground is higher, the automation degree of conducting hammer pressing and leveling work on the concrete ground by the large-areaconcrete ground high-flatness construction device is high, and time and labor saving during using is achieved; and a third motor on the leveling seat drives a square disc and the first hydraulic oilcylinder to be rotatably adjusted through a rotating shaft so as to enable the leveling seat to quickly patrol the protruding part on the ground, protruding points at the different positions on the ground are subjected to hammer pressing and leveling through the multiple hammer pressing plates arranged on the lower parts of the four edges of the square disc correspondingly, and the leveling efficiency of the large-area concrete ground high-flatness construction device on the concrete ground is improved.

The invention discloses a sand-washing blockage-removing steam injection tool. The sand-washing blockage-removing steam injection tool is sequentially provided with a matched oil well pump, a steam injection outer pipe, a bridge type sand-washing check valve, a sand-washing core pipe, a rotational flow sand-washing pipe, a thermal expansion telescopic pipe and an anti-falling inclined tip from topto bottom. The sand-washing blockage-removing steam injection tool has the advantages that the hidden danger of sand blockage is eliminated, the operation is simple, the replacement or maintenance isconvenient, the service life of an oil pipe is prolonged, and the well repair cost is reduced.

A leg stretching device is provided, which can provide a stable, efficient leg stretching effect for leg stretching methods and legs of users because the leg stretching device has flexible responses to the method and legs of users. The leg stretching device includes a fixed housing having a fastening hole and a coupling groove, a movable housing penetratingly coupled to the fastening hole of the fixed housing to be movable and having a support means provided on one side thereof to enable a user seated thereon, a pair of auxiliary housings detachably coupled to the coupling groove of the fixed housing in an opposite direction thereto, and a connection portion having one side connected to the fixed housing and the other side connected to the movable housing to control movement of the movable housing in a length direction thereof.
