A device for the gravimetric volume determination of liquid volumes comprises a housing (11) having the shape and dimensions of a standard rack used in a clinical diagnostic analyzer system for holding sample or reagent containers, and the following components contained in housing (11): a load cell (12) for gravimetric volume determination, a weighing container (13) for receiving a liquid to be weighed with said load cell (12), a windbreak (14) which shields said weighing container from air flow, an evaporation trap (15) which prevents evaporation of liquid loaded into said weighing container, a temperature sensor, an air-pressure sensor and a humidness sensor for sensing temperature, air pressure and humidness respectively at predetermined points within said housing, and an electronic processing unit for processing electrical output signals delivered by said load cell and by said sensors.

The invention relates to a hydraulic type bulk feed transportation vehicle. A power takeoff device is driven by the output power of an automobile gearbox; a high-pressure oil pump is transmitted to drive a hydraulic system; the high-pressure oil pump is connected with a distributing valve through a pipeline; three output ends of the valve are connected with a corner hydraulic motor, a lifting oilcylinder and a horizontal discharging hydraulic motor, vertical discharging hydraulic motor and movable discharging hydraulic motor in serial connection respectively; a discharging device consists ofa horizontal discharging system, a vertical discharging system and a movable discharging system which are spiral conveyors driven by the hydraulic motor; the horizontal discharging system is arrangedinside a tank body; the vertical discharging system is positioned outside the tank body; a feed port and a discharge port of the vertical discharging system are communicated with a discharge port of the horizontal discharging system and a feed port of the movable discharging system respectively; the lifting oil cylinder and a cylinder body of the movable discharging system are connected to realize up-and-down lifting; and the discharging device is also provided with a corner system for producing horizontal deflexion of the movable discharging cylinder body. The hydraulic type bulk feed transportation vehicle has the advantages of reducing packaging cost, saving feed, avoiding causing pollution in the loading and unloading and transportation links.

The invention relates to the field of slag dredging machines, and discloses a slag dredging machine. The slag dredging machine comprises a slag dredging pool (1), a main water supply pipeline (2) provided with a chain flushing water pipeline (3), a manual door continuous water supply pipeline (4), an electric door water supply pipeline (5) and an electric door emergency water supply pipeline (6),a water collecting pool (7), and a slag dredging machine emergency water supply pipeline (8); and along with lowering of the liquid level of the slag dredging pool (1), the electric door water supplypipeline (5), the electric door emergency water supply pipeline (6) and the slag dredging machine emergency water supply pipeline (8) are opened in sequence. In the slag dredging machine, a concentrator, a concentrator sewage pump, a dedusting water pump and a slag water medicine charging system are canceled; the slag dredging pool is basically not disturbed by the external, so that the precipitation effect is better; and the water collecting pool only receives less water without easily generating blockage, so that the slag dredging machine is reliably operated, and the slag dredging efficiency is improved.

A leg portion is provided at a second connector so that a gap is created between a flat circuit body and a circuit board. The leg portion also serves as a positioning projection, and a locking hole for being engaged with the positioning projection is provided at the flat circuit body. A guiding groove for receiving the leg portion is formed at a first connector. A guiding part for receiving the first connector in a sliding manner is formed at an end of an opening of the first connector, and an inclined part for sliding the guiding part there along is formed at an end of an engaging part of the second connector.

The invention discloses a micro-blanking automation device and method of a sheet metal under indirect impact of laser. The micro-blanking automation device comprises a laser generating system, an automatic forming system and a control system, wherein the laser generating system is composed of a laser controller, a laser emitter and an optical fiber, the automatic forming device is composed of an end cap, a focusing lens cone, a machine body, a micro-blanking worktable, a three-coordinator moving chuck, a base, a varying magnetic field device, a rotary table multi-position device, a restraint layer-fly piece integrated piece, a restraint layer-fly piece integrated piece storage bin and a recovery device. According to the micro-blanking automation device and method of the sheet metal under the indirect impact of the laser, pulse laser is used as a forming power source, energy conversion between optical energy and mechanical energy is conducted through a restraint layer-fly piece integrated piece device, and therefore automation of the micro-blanking technology that the sheet metal is loaded through a fly piece driven by the pulse laser is achieved. The automatic forming system is relatively independent, the machining precision is free from external interference, and personal errors are avoided. Both laser circuits and the micro-blanking worktable are stored inside the machine body so that safety of experimental operation is improved.
