TThe invention relates to a air compression aeroengine that uses turbine supercharged air compressor to produce high temperature and high pressure gas, then uses the counteractive thrust caused by compressed gas spraying from the over-spray nozzle to realize vertical lift and fly forward. The simple structure would decrease the cost. The noise is low. The invention is suited in civil aviation, cargo liner, fighter plane, bomber, and other aircrafts.

The invention relates to an ethylene oxide preheating, sterilization and resolution integrated cabinet and a sterilizing method. The integrated cabinet comprises a cabinet body, wherein a sealing door is arranged on the front part of the cabinet body; a cavity in the cabinet body is connected with a vacuum pump through a vacuumizing pipeline; the cavity in the cabinet body is connected with a humidifying device through a humidifying pipeline; the cavity in the cabinet body is connected with wet and hot air making devices through wet and hot air delivery pipelines; a heating water jacket is arranged outside the cabinet body; a circulating air pipeline is arranged on the outer side of the cabinet body; a fan is connected in series to the circulating air pipeline; an air inlet of the circulating air pipeline is arranged on one side in the cabinet body; an air outlet of the circulating air pipeline is arranged on the other side in the cabinet body; and the cabinet body is connected with an ethylene oxide container through a pipeline provided with a valve. The ethylene oxide preheating, sterilization and resolution integrated cabinet has the advantages of high operating efficiency, few matched facilities, low fault rate, short construction period, low daily using cost and low energy loss, and can reduce pollution to human body and environment and improve the comprehensive benefit by over 40 percent.

The invention discloses an online weighing and coding device. Online weighing, code reading and coding can be achieved. In the using process, a read-write electronic code is arranged at the bottom of a bottle, a conveyor belt conveys the bottle to the portion below a bottle grasping mechanical arm, a lifting device descends, the bottle grasping mechanical arm grasps the bottle, a horizontally-moving device horizontally moves the bottle grasping mechanical arm to the portion above a weighing device after the lifting device ascends, the lifting device descends so that the bottle drops on the weighing device, the bottle grasping mechanical arm loosens the bottle, the weighing device weighs a coal sample in the bottle, and after being acquired, weight information of the coal sample is written into the read-write electronic code through a coding device and covers original information in the read-write electronic code. Accordingly, daily use cost is reduced, automatic storage and search and automatic recognition are achieved, and code reading and coding are facilitated.

The invention relates to a hydraulic control system of a fixed-type steel grabbing machine. The hydraulic control system is characterized by comprising a hydraulic oil tank (5.1), a hydraulic oil pump (5.2), a first motor (5.3), a multi-way valve (5.4), a back pressure check valve (5.5), a cooler (5.6), a filter (5.7), a rotary platform motor reducer assembly (5.8), a large-arm oil cylinder balance valve (5.9), a bucket arm cylinder balance valve (5.10), a grabber oil cylinder (5.11), a grabber rotating drive assembly (5.12), a pilot oil tank (5.13), a drive oil pump (5.14), a second motor (5.15), a pilot oil source block (5.16), a first operating lever pilot oil valve (5.17), a second operating lever pilot oil valve (5.18) and a third operating lever pilot oil valve (5.19). The hydraulic control system has the advantages of convenience in installation, appropriate price, safety in operation and simplicity in structure.

The invention relates to a light durable printing roll. The light durable printing roll comprises a mandrel, a cylindrical roll body and an auxiliary limiting piece. The mandrel is composed of a left end shaft, a right end shaft and a middle main shaft, and the upper portion of the mandrel is provided with a limiting clamping shoulder A. The cylindrical roll body is made of high-intensity non-metal materials, and the outer surface of the cylindrical roll body is painted with a high-temperature alloy abrasion resistant layer. The mandrel and the roll body can be assembled into a whole through the auxiliary limiting piece. The auxiliary limiting piece includes a limiting clamping shoulder B and a nut. The mandrel and the roll body are split into two independent components which can be conveniently assembled into a whole the same as an existing metal printing roll in shape and size. The mandrel and the auxiliary limiting piece are respectively made of corrosion resistant metal materials, the roll body is made of carbon fiber materials with high tensile strength and acid and alkali solution corrosion resistance, and the printing roll is light in overall weight, low in working noise, high in corrosion resistance and abrasion resistance, reliable in working, long in service life and low in daily use cost; the printing roll and the existing metal printing roll have interchangeability, so that the printing roll has high practicability and wide market application prospects.

The invention relates to an inflating-free pneumatic tire. A main body of the inflating-free pneumatic tire consists of a crown and a bead toe which are connected into a whole, wherein the crown comprises a carcass and a wear-resistant layer; an embedded clamping strip is arranged on the bead toe; five buffer air cavities are formed inside the carcass; a left limiting groove and a right limiting groove are externally formed in the joint of the bead toe and the carcass, and a left rectangular buffer air cavity and a right rectangular buffer air cavity are internally formed in the joint of the bead toe and the carcass; the interval between cavity walls of each buffer air cavity is the same; during working, an elastic supporting rib system enabling the tire to have reliable working elasticity is composited, and an anti-puncture pressure bearing working area, an assembly force bearing working area and an assembly limiting elastic working area are formed on the surface of the tire, so that the inflating-free pneumatic tire has reliable working elasticity, an excellent anti-puncture function and a longer reliable working service life; moreover, compared with a conventional automotive inflatable tire, the inflating-free pneumatic tire has general interchangeability, high practicality and excellent economical efficiency.
