The invention discloses a horizontal desorption device, which belongs to the technical field of active material extraction devices. The horizontal desorption device comprises a base, a power transmission mechanism, a revolving drum shaft, a tank, a desorption revolving drum and a medium introduction sleeve, wherein a shaft body of the revolving drum shaft is provided with heating medium inlet andoutlet and condensate inlet and outlet; the tank consists of a tank base and a tank head; and the desorption revolving drum comprises a desorption cylinder body, an isolating sleeve, a condensate extraction tube, a material introduction tube and a revolving drum fixing disk. The horizontal desorption device is characterized in that: the desorption cylinder body has a shape of a cone frustum with a small end and a big end, wherein the small end is fixed to the revolving drum fixing disk; the wall of a port of the big end is provided with a nozzle with a nozzle cavity; the wall of the tank headis connected with a material storage tank on which a material outlet tube is matched; and the centre of the bottom wall of the small end of the desorption cylinder body is fixedly provided with a material distribution cylinder, and the material introduction tube extends in to the material distribution cylinder. The horizontal desorption device can enhance the desorption effect of a liquid medium and improve the desorption efficiency, puts an end to escape of materials, and has an ideal saving effect.

The invention discloses a multipurpose torque loading operation test method. A motor drives a test turntable through a transmission gear in a variable-speed mode, then, the rotating speed and the transmission direction are changed through a right-angle transmission box, a slurry pump is driven to generate high-pressure slurry liquid, the high-pressure slurry liquid flows through a pressure regulating device for pressure reduction and flows back to a slurry tank, and the discharging pressure of the slurry pump is regulated, so that the slurry pump becomes a load with the adjustable torque, the torque load with the adjustable size is indirectly exerted on the test turntable, and the actual output torque of a test object is monitored through a torque sensor. The invention also discloses a multipurpose torque loading operation test device. The method and the device have the advantages that the arrangement is flexible, the torque loading test of various kinds of products can be realized through regulating the equipment arrangement, the universality of a test table is improved, the repeated construction is avoided, and the economizing effect on petroleum drill and exploitation equipment manufacturing enterprises is obvious.

The invention advances a method for calling user terminal in wireless communications system; with the method, calls are classified according to the mobility of UE; the system starts calling all communities in the position area for calling the mobile UE, and the system starts calling in the community in which the UE is located first for calling static UE and then calls all communities in the position area if the UE could not be called. By adopting the method, calling information flow volume could be reduced to decrease the load of every base station controller and the blockage of information is deduced to promote the call completion rate; at the same time, a large amount of call channel resource could be saved, especially for most users in prosperous downtown or office buildings who are static with limited wireless resources, the effect is obvious.

The invention discloses a detection unit for an online negative pressure air suction conveying device of a roll paper die-cutting machine belt. The detection unit comprises the conveying device, negative pressure cavity boxes, a foldable negative pressure cavity box, a sliding device of the foldable negative pressure cavity box and a belt supporting frame. The negative pressure cavity boxes and the foldable negative pressure cavity box are arranged on the lower face of a conveyor belt and the foldable negative pressure cavity box can slide, stretch and retract in one negative pressure cavity box. A negative pressure cavity panel is arranged on the negative pressure cavity boxes and the foldable negative pressure cavity box. The negative pressure cavity boxes are fixed to a rack, the foldable negative pressure cavity box is fixed to the sliding device, and the sliding device is connected with a cylinder. The negative pressure cavity boxes and the foldable negative pressure cavity box are provided with connectors and connected with an exhaust fan. The belt supporting frame is a mesh type frame arranged on the negative pressure cavity panel. A dust removal device and a connection device can be additionally arranged on the detection unit. Products can be stably and accurately conveyed to a detection device through the negative pressure air suction conveying device.

The invention relates to a glue gun comprising a flexible glue tube. By means of the hollowed-out circular arc-shaped channel technology, the flexible glue tube is directly used for conducting glue applying operation. The operation process is visual. The effects of improving the construction quality and reducing the packing material cost, the accident rate and the quantity of generated glass gluepackage waste are achieved.
