A flexible magnetically coupled pushbutton switch assembly has a coupler layer magnetically held against a flexible layer that has flaps that function as flexible armatures. The flexible armatures are normally magnetically coupled to the coupler layer. The coupler layer is a sheet of magnetic receptive rubber material that includes debossed spacers, and there are embossed crowns in the flexible armatures. The embossed crowns fit into openings in the coupler layer so that a switch user may manipulate the flexible armatures. The debossed spacers support the flexible layer above a bottom layer such that there are armature cavities for the flexible armatures. An arrangement of electrical conductors is affected when a switch user selectively manipulates a flexible armature so that an electrical circuit connected to the electrical switch is opened or closed when the switch is actuated.

A wall stud for positioning between an opposing pair of formwork boards. The wall stud including a body and two side walls located on opposing sides of the body. Each side wall having an inner face and an outer face, wherein: the body has at least one opening adapted to receive at least one reinforcing rod. The outer face of the side walls are securable to a formwork board, and the body is affixed to approximately the center of the inner face of each side wall so that a horizontal cross-section of the stud is substantially an H shape.

The invention provides a water-based metal antirust agent, which consists of the following components in parts by mass: 6-8 parts of sodium benzoate, 3-5 parts of sodium silicate, 3-5 parts of triethanolamine, 2-3 parts of barium sulfate 1-2 parts of acrylamide, 1-2 parts of sodium chloride, 1-2 parts of disodium hydrogen phosphate, 0.5-0.8 parts of isobutanol, 8-10 parts of ethanol, and 75-85 parts of water. The present invention also provides a preparation method of the above-mentioned water-based metal antirust agent. The water-based metal antirust agent of the present invention can be used for antirust in process, short-term storage and transportation, and can also be used in hydraulic equipment requiring antirust. The metal can be protected from rust by soaking, spraying, brushing, etc.; under normal circumstances, it can keep the metal rust-free for 130-160 days.

The invention proposes a high-alkalinity high-strength sulphoaluminate cement. The cement includes sulfoaluminate clinker, 30%-90%; potassium hydroxide, 0.1%-5%; component A, 4.9%-55%; gypsum, 5%-30% in mass percentage ; The component A is a silicon-aluminum material and / or a siliceous material; the sulfoaluminate clinker includes C in mass percentage 2 S, 30%‑60% (α' type C 2 S, 30%‑60%; beta C 2 S, 40%‑70%); C 4 AF, 5%‑30%; 2C 2 S·CaSO 4 , 1%-5%; component B, 28%-64%; said component B is CaSO 4 with a mixture of . The cement is used in marine engineering construction, and can provide high alkalinity to prevent corrosion of steel bars in the early stage of construction, and can provide high strength to improve its service life in the later stage, and has good comprehensive performance, so it is more practical.

The invention relates to a bladder power pump utilizing the magnetic force to assist the bladder to urinate, which comprises a magnetic active cell (1), a stator (2) and a magnetic controller (3), wherein, the magnetic controller (3) generates magnetic field if switched on and enables the magnetic force to work on the magnetic active cell (1); the magnetic active cell (1) comprises a flexible sheet (12) and a plurality of permanent magnetic sheets (13), and the permanent magnetic sheets (13) are enwrapped with the flexible sheet (12); the flexible sheet (12) enwrapping the permanent magnetic sheets (13) surrounds a gourd-shaped structure with the stator (2) to circle the outside of the bladder (10) to build a variable working cavity (11); the upper end of the flexible sheet (12) enwrapping the permanent magnetic sheets (13) is contacted and adhered with the stator (2); a through hole (9) of ureter communicating a ureter (8) with a ureter port (a) inside the bladder wall, and a urethrabayonet (7) held at a urethral meatus (b) of a urethra (8) are respectively arranged at the lower end of the flexible sheet (12) where the permanent magnetic sheets (13) are not enwrapped; and the lower end of the flexible sheet (12) where the permanent magnetic sheets (13) are not enwrapped is contacted and adhered with the stator (2). The invention can effectively assist the neurogenic bladder dysfunction sufferer to realize emiction and has the advantages of ingenious design, simple structure, safe use, convenience and practicality.
