An improvement to the usable lifetime of a lamp includes the use of a primary filament, a backup filament, and a means to switch portions of the backup filament into the current flow path after a portion of the primary filament open circuits. Using bypass shunts, which do not become electrically conductive until a portion of the primary filament open circuits, an open circuited portion of the primary filament can be electrically replaced with an associated backup filament portion to keep the lamp lit. The shunts in one embodiment are made of oxidized wire and are wrapped around the primary and backup filaments, in a spaced-apart relation, forming filament pairs consisting of a primary filament segment and its associated backup filament segment. In another embodiment, support brackets are used to not only support the primary and backup filaments, but are also used to provide the bypass shunt function as well.

Wear members for use in excavating include a socket having a front stabilizing end that includes a top surface, a bottom surface and side surfaces. At least one of these surfaces is formed with a transverse, inward projection and extends axially substantially parallel to the longitudinal axis of the socket. The socket may include surfaces that generally correspond to exterior surfaces of a nose on which it may be mounted and on which it may be connected to excavating equipment.

The invention discloses a timing charging device capable of prolonging a service life of a lithium battery. A shell is included. A working cavity is arranged in the shell; a voltage-stabilizing lithium battery pack is fixedly arranged on an inner wall of a lower side of the working cavity; a cooling assembly is arranged on the inner wall of a right side of the working cavity; and the cooling assembly further comprises a first transmission shaft rotatably connected with the inner wall of the right side of the working cavity. In the invention, a timing assembly is adopted; a fixed conductive block and a conductive sliding block are abutted against each other regularly so that timing power-on of an external power supply and the voltage-stabilizing lithium battery pack is realized and timing charging of the voltage-stabilizing lithium battery pack is realized too; the voltage-stabilizing lithium battery pack is prevented from being overcharged or overdischarged; a fan is adopted, the voltage-stabilizing lithium battery pack can be cooled when being charged or overheated, and the service life of the voltage-stabilizing lithium battery pack is prolonged; and an over-temperature protection assembly is adopted, the fan can rotate when the voltage-stabilizing lithium battery pack is overheated, and the service life of the voltage-stabilizing lithium battery pack can be ensured not to beshortened due to a fact that the temperature is too high.

The invention discloses a free-disassembly constructed wetland purifying device which comprises a constructed wetland purifying device and is characterized by mainly consisting of a water collection channel, a water-in pipe, a front beam, a middle beam, a rear beam and five layers of water-permeable boxes, wherein each water-permeable box is composed of a box body, an X-shaped connection rope box connected with the four corners of the box body and a hanging rope connected with the joint of the X-shaped connection rope body; a hook is arranged at the middle part of the outer bottom surface of the box body; a water outlet is arranged at the lower end part of the two side walls of the box body respectively; and a glass rubble layer is paved in the box body of the water-permeable box. In the constructed wetland purifying device disclosed by the invention, the box body, the connection rope body, the hanging rope and the hook are all made of a stainless steel material, and thus the constructed wetland purifying device has the characteristics of excellent corrosion resistance, formability and compatibility, toughness in a very wide temperature range and the like; and moreover, the utilization efficiency is improved, and the cleaning and disassembly difficulty is reduced. The free-disassembly constructed wetland purifying device disclosed by the invention is suitable for sewage treatment in urban or rural areas.

The present application provides a data storage method, device, electronic device and storage medium. The method includes: acquiring attribute information of each storage unit in the current storage medium; wherein the attribute information is used to represent the degree of damage of the storage unit; The attribute information of the unit determines the high fault-tolerant unit in the current storage medium; judges whether the data to be stored is high-fault-tolerant data; when the data to be stored is high-fault-tolerant data, the to-be-stored data is stored in the high fault-tolerant unit. The method provided by the above solution extends the usable life of the storage unit by using the severely damaged storage unit as the high fault-tolerant unit and using the high fault-tolerant unit to store the high-fault-tolerant data, thereby prolonging the overall usable life of the storage medium.
