In an aircraft cabin floor adjacent to the cockpit, a trap door opens downwardly into a security cell, to trap a terrorist trying to enter the cockpit. Two walls with lockable airtight doors bound a safety buffer cabin between the cockpit and the passenger cabin. Sensors like seat occupancy sensors, motion detectors, video cameras and microphones provide data regarding the location, movement and activities of passengers to a system that evaluates the data to recognize unusual data situations indicating one or more escalation levels of suspicious or aggressive actions by passengers. Alarm signals and terrorist countermeasure devices such as fogging or tranquilizer gas generators, noise generators, high intensity blinding / glaring lights, a cabin lighting master shut-off, window darkening devices, and tranquilizer dart guns are actuated automatically by the evaluation system, or manually by a cockpit input device or a portable signaling device carried by a flight attendant.

The invention relates to a steel ladle edge covering structure, belonging to the technical field of steel-making steel ladle construction. The steel ladle edge covering structure is characterized in that vertical-type wedged metal press plates are welded in a discontinuous manner along the circumferential direction of a ladle opening, and thus the distribution density of the vertical-type wedged metal press plates increases; horizontal annular metal press plates are continuously welded along the circumferential direction of the ladle opening on the vertical-type wedged metal press plates, and the horizontal annular metal press plates, a covering shell and the vertical-type wedged metal press plates are welded together; wedged edge-covering bricks are matched with the vertical-type wedged metal press plates to be built, and a ladle opening ramming material is filled between the vertical-type wedged metal press plates and the wedged edge-covering bricks. The steel ladle edge covering structure has the advantages that the deformation of the press plates can be alleviated, the possibility that the bricks drop off from the covered edge can be lowered, a transverse seam in a working layer can be avoided, the turnover rate of a steel ladle can be improved, the non-planned ladle throwing can be reduced, and the service life of the steel ladle can be prolonged.

The invention relates to the technical field of bartack sewing machines, in particular to a presser foot used for a bartack sewing machine. The presser foot comprises a presser foot base and a presser foot plate. A pressing rod and a connection rod are arranged between the presser foot base and the presser foot plate. One end of the pressing rod is hinged to the presser foot base, and the other end of the pressing rod is hinged to the middle of the presser foot plate. The presser foot plate rotates relative to the presser foot base together with the pressing rod. The rotation angle of the pressing rod is alpha. One end of the pressing rod is hinged to the end of the presser foot plate, and the other end of the pressing rod is connected into a slide groove in the presser foot base in a sliding mode. The presser foot is simple in structure, wide in application range and good in cloth pressing effect, the angle of the presser foot plate can be automatically regulated, and unsmooth and uneven cloth can be effectively pressed; meanwhile, the pressing rod rotates to generate an included angle smaller than 90 degrees relative to the horizontal plane after the pressing rod is pressed downwards. When the cloths moves reversely, the pressing force can be improved, the processed cloth can only enter the bartack sewing machine but can not leave the bartack sewing machine, and the cloth is prevented from being scratched when moving reversely.

The invention discloses an anti-seepage outer wall thermal insulation and decoration finished board, which is easy to install and has a good anti-seepage effect. The top edge of the outer wall insulation decoration finished board is provided with an inward concave notch, and the bottom edge of the finished board body of the exterior wall insulation decoration is provided with an outwardly protruding convex head, in which the notch is engaged with the convex head; the main body of the finished exterior wall insulation decoration board and There is a water barrier between the main bodies of the finished thermal insulation and decoration boards on the side of the outer wall. The main body of each finished thermal insulation and decoration board of the outer wall is provided with auxiliary sticking blocks and hooks. The auxiliary sticking blocks are arranged at intervals and placed on the finished thermal insulation decoration Between the main body of the board and the wall, the auxiliary pasting block is fixed on the wall by expansion bolts, and the main body of the finished thermal insulation decoration board fits with the auxiliary pasting block; one end of the hook is fixed on the wall, and the other end is inlaid on the outer wall Insulation is trimmed on the finished panel exterior walls.

The invention provides an automatic sensing and control method of friction stir welding trajectory suitable for fillet joints. The method firstly measures the welding seam data in real time by a data measurement module, and calculates the adjustment data of the stirring head according to the measured data by a data processing module. The mechanical control module implements the adjustment command of the stirring head, so that the process of welding fillet joints does not need manual adjustment. For straight right angle welds or arc right angle welds, the position of the stirring head can be automatically adjusted to complete the welding. The invention realizes the automatic welding of the friction stir welding fillet joint and the automatic adjustment of the welding track, and improves the welding production efficiency.

The invention provides a sunshade umbrella for sports. The sports sunshade includes: a central shaft; a second support mechanism, the second support mechanism includes a third support rod, a fourth support rod, a first fixed block, a second fixed block, a third fixed block and a spring , a connection mechanism, the connection mechanism is connected to the other end of the third support rod; a first support mechanism, the first support mechanism is sleeved on the connection mechanism. The sunshade umbrella for sports provided by the invention has the advantages of single-person operation, multi-directional sunshade, small occupied space, convenient movement, and high space utilization rate at the bottom of the sunshade umbrella.

An anti-warping design method for designing a resin molded article on a programmed computer includes dividing the molded article into a plurality of small elements, calculating sensitivity values for at least part of the elements with respect to warpage of the molded article, and displaying a distribution of the sensitivity values.

The invention discloses a fixture for manufacturing a current transformer. The fixture comprises a tray which is used for bearing the current transformer and a laminated plate. A plurality of holes for placing the current transformer are formed in the tray. The area of the laminated plate is equivalent to the area of the tray and the laminated plate fully covers the entire tray. The quick assembling of the current transformer can be realized and the consistency of coplanarity is realized. The invention additionally discloses a manufacturing method of the current transformer. By using the manufacturing method, the reject ration of the current transformer can be reduced and the production efficiency is improved.
