A particularly efficient heat transfer can be achieved with at least one metallic heating body (13) which is exposed in the pre-heating chamber (10) to the fuel and in which the at least one heating element (12) is introduced.

Disclosed is a main transmission clearance eliminating mechanism of a mechanical servo numerical control turrent punch press, which is capable of keeping an impact head to contact with a roller and comprises an oblique block, the impact head and a fixing seat. The oblique block is horizontally slidably connected onto a machine body, the impact head is perpendicular to a horizontal plane, is movably connected onto the machine body, is inversely convex and consists of an impact head portion and an impact head body, the impact head portion is positioned on the upper portion of the impact head, the impact head body is positioned on the lower portion of the impact head, the upper portion of the cylindrical fixing seat is open, the fixing seat is fixedly connected onto the machine body, a center hole is arranged at the bottom of the fixing seat, the inner diameter of the fixing seat hermetically matches with the impact head portion, and the center hole of the bottom of the fixing seat matches with the impact head body in a hermetic seal manner. The main transmission clearance eliminating mechanism is additionally provided with the fixing seat with functions of a cylinder, and simultaneously, the impact head is improved into a big-end-up two-section shape and has functions of a piston. When communicated with the lower portion of the fixing seat, a high-pressure gas source can provide upward force for the impact head, and accordingly the roller is prevented from contacting with the oblique block. During operation, the roller and the oblique block always contact with each other, and accordingly, transmission stability and precision stability are kept.

The invention discloses a single-phase electronic intelligent electric meter plug-in device, The structure comprises a casing, a connecting part and a pressing block, wherein the connecting part is fixed by the pressing block after being inserted with the casing, two grooves for inserting the connecting part are arranged on the casing in parallel, two side walls corresponding to the grooves are respectively provided with a cantilever beam, and the upper end of the cantilever beam is provided with a V-shaped socket convenient for inserting the connecting part. The plug-in device has simple structure and reasonable design, and can prevent the electrode from being misinserted, deflected or unable to be inserted, prevent the contact from fatigue failure, and ensure the safe operation of the electric meter.

The invention discloses a foundation reinforcing device and a use method thereof. The foundation reinforcing device comprises a foundation device and a reinforcing device body, an upper locking nut and a lower locking nut are arranged on a foundation bolt in a thread manner, the upper locking nut is located on the upper side of a foundation flange, the lower locking nut is located on the lower side of the foundation flange, the reinforcing device body comprises a reinforcing plate and a reinforcing bolt, the reinforcing plate is provided with a penetrating groove with a leftward opening and athrough hole in the up and down direction, the penetrating groove of the reinforcing plate wraps the upper end and the lower end of the edge of the foundation flange, the reinforcing bolt penetrates the bolt and is located on the outer side of the foundation flange, an upper reinforcing nut and a lower reinforcing nut are in threaded connection to the reinforcing bolt, the lower portion is embedded in a foundation base, the upper reinforcing nut is located on the upper side of the reinforcing plate, and the lower reinforcing nut is located on the lower side of the reinforcing plate.
