A demolding kit for concrete products to be molded and demolded. The demolding kit comprises a deformable mold having two rigid spines, a longitudinal mold volume extending transversally to the spines for molding a product, and a resting face opposed to the mold volume; and a bed having a non-matching shape relative to the resting face of the deformable mold. Clearance between the resting face and the bed about at least one of the spines is present when the resting face rests on the bed without exterior force applied thereon. The deformable mold is configured to have the resting face at least partially adopting the shape of the bed when exterior face is applied on the spines, thereby at least partially releasing the product from the mold volume.

The invention discloses a rigid spine endoscopic surgery robot module capable of rapidly switching instruments and a switching method.The rigid spine endoscopic surgery robot module comprises a base, a rigid instrument assembly, an overall rotating mechanism and an instrument feeding mechanism are arranged on the base, the rigid instrument assembly comprises an instrument base, and a guide rail sliding block assembly is fixed to the outer portion of the instrument base; the sliding block is connected with a rigid surgical instrument through an instrument connecting piece; the instrument feeding mechanism comprises a lead screw feeding device; an elastic connecting mechanism is installed on a nut of the lead screw and comprises a nut fixing piece, a spring, a floating connecting piece and a stand column. The nut fixing piece is fixedly connected with the nut and connected with the floating connecting piece through the stand column and can move up and down relatively, and the axis of the spring is parallel to the stand column. A groove is formed in the top surface of the floating connecting piece; when the groove is in matched contact with the instrument connecting piece, the instrument connecting piece is driven to move forwards; the overall rotating mechanism is arranged at one end of the instrument base and drives the instrument base.

Apparatuses, systems, and methods including a cargo transport system are disclosed. The cargo transport system includes a spine assembly, a container assembly, and an outer fairing. The spine assembly includes a rigid spine and a plurality of mounts arranged on the rigid spine in a plurality of mounting rows. The container assembly includes a plurality of containers secured to the spine assembly using at least a subset of the plurality of mounts. The outer fairing at least partially encloses the container assembly. Each container of the plurality of containers includes a plurality of fittings for securing the container to the spine assembly and / or another container of the container assembly. The container assembly is enclosed within a pressurized space for pressurizing the container assembly.

A loose-leaf notebook, comprising a front cover plate (1), a rear cover plate (2), a flexible-rigid spine (3), and a binder (4). The flexible-rigid spine (3) comprises a rigid spine body (3-2) and flexible hinge bodies (3-3). The two sides of the rigid spine body (3-2) are each provided with one flexible hinge body (3-3), and the two flexible hinge bodies (3-3) are respectively connected to the front cover plate (1) and the rear cover plate (2). The flexible-rigid spine (3) combines flexible and rigid materials, allowing for easy unfolding or folding, so that the loose-leaf notebook of the present application can be opened or closed smoothly and without obstruction. Moreover, the front cover plate (1) and the rear cover plate (2) can be fully flattened when opened, and can be neatly folded when closed. When the loose-leaf notebook is closed, the rigid spine body (3-2) is supported between the front cover plate (1) and the rear cover plate (2), so that the front cover plate (1), the rear cover plate (2), and the rigid spine body (3-2) form a stable three-sided structure, enabling the loose-leaf notebook to stand vertically on a desktop, facilitating vertical storage of the loose-leaf notebook.
