A battery-operated screwdriver (10) with a housing (12, 18) with a grip (14), in particular with a fixedly built-in battery (40), and with charging contact tongues (37) for charging the battery (40), is designed as especially compact and lightweight because instead of a boxlike, standard ON / OFF switch, counterpart contacts (34) fixed to the tool are provided, to which a contact plate (32) that is movable by means of an ON / OFF trigger (26) and in the process is coupleable to the counterpart contacts (34) and upon their release is easily releasable, is assigned.

The invention relates to a fully-automatic mahjong machine comprising a board sending system, a board loading system, a board lifting system and a large shuffling disc. The board sending system comprises four board sending mechanisms, each board sending mechanism comprises a transmission rack, and a board sending motor, a board absorbing wheel, a transmission belt, a transmission platform, a board inlet guiding piece and a board outlet guiding piece fixed on the transmission rack; a board sending channel is arranged at the upper end of the transmission platform, the board absorbing wheel is tightly attached at the lower end of a board inlet opening of the board sending channel, the board inlet guiding piece is positioned above the board absorbing wheel, the board outlet guiding piece is positioned at a board outlet opening of the board inlet channel, the board sending motor is used for driving a motor guiding wheel, the motor guiding wheel is positioned below the transmission platform, and the transmission belt loops the motor guiding wheel, the board absorbing wheel and the transmission platform. In the invention, for the mahjong boards with different widths, the board sending mechanism of the mahjong machine can run normally by only replacing the corresponding board inlet guiding piece and the board outlet guiding piece, and a transmission rack cover does not need to be changed, so that the operation is simple and convenient, and the board inlet guiding piece and the board outlet guiding piece has extremely low production cost relative to the transmission rack cover.

The dimensionally stable alkaline solid block warewashing detergent uses an E-form binder forming a solid comprising a sodium carbonate source of alkalinity, a metal corrosion protecting alkali metal silicate composition, a sequestrant, a surfactant package and other optional material. The solid block is dimensionally stable and highly effective in removing soil from the surfaces of dishware in the institutional and industrial environment. The E-form hydrate comprises an organic phosphonate and a hydrated carbonate.

A laptop computer has an exhaust port on a rear panel. A thin film skin is engaged with the computer placing a generally planar top panel and a generally planar bottom panel on the computers top and bottom exposed faces. The panels are joined by an elastic hinge around the rear panel. Comer grippers are engaged with the computer's corners to enable the skin to fit tightly on the computer. The hinge has such an elastic property, that, with the comer grippers engaged with the computer, the hinge lays in a stretched condition proximate the rear panel with the computer open or closed thereby preventing bulging of the hinge or thin film panels.
