The invention provides a multi-curved surface overhung copper plate curtain wall and a construction method thereof. The primary keel thereof is a steel truss. The outer side of the main keel steel truss is connected with a transverse secondary keel. The four sides of the curtain wall panel are provided with hems. The screw of the curtain wall panel is connected with the secondary keel by a combined adjustable hanger and a bolt. The combined adjustable hanger is formed by connecting any two or three of following hangers end to end: the first hanger that is an L-shaped folded plate structure with the horizontal plate surface provided with an oblong hole along a central line and a vertical plate surface provided with a circular hole, the second hanger that is a folded plate structure with two platforms folded plate for three times with an angle of 90 degrees and an upper platform plate surface provided with an oblong hole along the central line and the vertical plate surface provided with a circular hole, and the third hanger that is an L-shaped folded plate structure with the horizontal plate surface provided with one to two oblong holes along the plate width and the vertical plate surface provided with an oblong hole along the central line. The construction error caused in the process of mounting the plates can be eliminated by the combined adjustable hanger and the variation of multi-curved surface plates in continuous curved space is satisfied. The invention solves the technical problem of mounting the multi-curved surface copper plate curtain wall.

The preferred electronic-carrying module (640) includes, first, an electronics carrier (106) having access means (107) for providing an easy-to-reach access to wrap-around circuitry fitted inside a curved space (104a) within the electronics carrier (106). Second, a pair of rigid end-fittings (102) spaced apart axially by the electronics carrier (106) for connecting to a section of the seismic data acquisition cable (400). And third, an axial hole (100) formed in the electronics carrier (106) and the rigid end-fittings (102) defining the curved space (104a) between the axial hole (100), the access means (107) and the rigid end-fittings (102).

An adjustable camera flash mounting bracket device for rapid camera flash repositioning in relation to a camera attachment platform in selective orientation.

Multiple rotatable guide members are secured within the curved flash engagement portion and are received within complimentary grooves in the flash mounting base. Retainment force applied by spring urged guide members permits for selective rotation within the curved flash mounting base to be grippingly retained therewithin at user select position orientation in relation to the fixed camera mount.

The invention mainly discloses a retractable gymnasium roof with an ultra large curved space and a control method thereof. A large multi-point hydraulically-actuated hoister is used for pulling the movable roof to realize the retraction and the extension of the roof, the movable roof is supported and driven to move by trolleys mounted on a main arch track of the gymnasium, the hoister pulls the movable roof under the control of a central control system to enable the roof to move along the main arch track so as to complete the inward retraction or the outward extension of the roof, and the position and the height of each support trolley is adjusted according to the relative design height and the lateral deviation extent of the gymnasium arch in the moving process of each trolley so as to ensure the smooth slippage of the roof and the integral structural safety of the gymnasium. By establishing a secure foundation based on a mechanical model and realizing technical breakthrough in multiple aspects of construction, structure, machinery and control, the invention ensures the safe, smooth and long-time movement of the movable gymnasium roof.

The invention discloses a preparation method of foamed nickel based on a P-curved space structure, and belongs to the field of high-temperature structural material preparation. The preparation methodmainly comprises the following steps: 3D printing a P-curved space structure by using PLA material, preparing a coating slurry, and pouring the coating slurry. Regarding the foamed nickel material prepared according to the method, the porosity and structure of the to-be-prepared foamed nickel material can be directly controlled by controlling the parameters of the P-curved space spatial structure,so as to achieve suitable mechanical properties. The foamed nickel material having a P-curved space structure not only has the characteristics of high porosity, small specific gravity, large specificsurface area, high specific strength, good damping and shock absorption performance, excellent heat insulation and sound insulation performance which common foamed metal has, the foamed nickel material according to the method also has an adjustable porosity to meet the specific performance requirements, so that the prepared foamed nickel is more suitable for the needs of the various industrial productions.

A node-link structure is laid out in a space with negative curvature, such as the hyperbolic plane. Nearby relationship data are obtained for an element in the structure, indicating information about nearby node-link relationships; then layout data for the element are obtained, based on the nearby relationship data. The layout data indicate the element's position relative to a parent in the negatively curved space. The layout data can indicate a position displacement and an angle displacement between the parent and the element. The nearby relationship data can be obtained by counting grandchildren of the parent for each child of the parent that is in a set that are being or have been laid out. The counts can be used to obtain a radius and an angle for each child in the set, and the radii and angles can be used to obtain the position displacement and angle displacement. The nearby node-link relationships can thus include only relationships among the parent and its children and grandchildren.

A buckling up phalanges joints type button input device and method use features that the phalanges joints can bend. A curved surface button input panel is installed inside sheathing. A curved surface mobile panel is installed corresponding to a curved surface of the button input panel, so as to form a curved space between the button input panel and the mobile panel. Fingers can stretch inside the curved space to operate buttons following an angle of the curved space. When either the curved surface mobile panel or the button input panel move, the curved space will become narrowed or extended. Once the curved space become narrowed, the phalanges joints will be locked on a turning point of the curved space due to a length of the fingers, so that the fingers cannot draw out. Thereby the phalanges joints will be locked if error data is inputted.

A space curving model demonstrator utilizes warping of a rubber membrane to vividly analog a curved space caused by gravity, and simulates and demonstrates difference between ball body moving trajectories when a moving ball body passes through a flat space without a gravitational field and a curved space with a gravitational field respectively, so as to show the existence of the gravitational field, that is, the space around the gravitational field is curved. The space curving model demonstrator has the advantages of simple structure, convenient operation, high visibility, visual and obvious phenomenon, low cost, safe demonstration, durable property, and easy popularization.
