摘要:
A fireworks connection structure for continuous discharge of groups of fireworks, including a group of fireworks formed by a plurality of firework tubes, wherein the group of fireworks further comprises female connecting firework tubes arranged at the head end of the group of fireworks for igniting the group of fireworks and at least one male connecting firework tube matched with the female connecting firework tubes; the female connecting firework tube can be amounted above the male connecting firework tube of another group of fireworks; the female connecting firework tube is equipped with a fuse inside, of which one end is inside the female connecting firework tube and the other end extends beyond the female connecting firework tube for igniting the group of fireworks; the fuse is positioned in the female connecting firework tube in such a manner that after the female connecting firework tube is amounted above the male connecting firework tube of another group of fireworks, the male connecting firework tube of another group of fireworks may ignite the fuse. The connecting method of the application is convenient and simple for there is no need to connect the actual fuses manually, so that the risk of accidents upon connecting fuses may be prevented. Moreover, with this method, groups of fireworks can be connected and detached quickly, without any damage to the fireworks devices, making possible versatile combination and arrangement between fireworks groups in an easy manner.

Provided is a method of producing a microporous sheet material of a polymeric matrix of polyolefin, with finely divided and substantially water-insoluble filler distributed throughout the matrix, and a network of interconnecting pores communicating throughout the microporous material. The method includes: (a) forming a mixture of polyolefin, filler and a processing plasticizer composition; (b) extruding the mixture to form a continuous sheet; and (c) contacting the continuous sheet with a non-flammable extraction fluid composition to extract the processing plasticizer composition from the continuous sheet. The extraction fluid has a boiling point of 75° C. or less, and is essentially free of trichloroethylene. The microporous sheet material has Tensile Strength equal to or greater than 800 kPa. A microporous sheet material also is provided.

The invention discloses a continuous driving mileage calculation control system and a calculation control method. The calculation control system comprises an MCU microprocessor, a continuous driving mileage digital display, a vehicle speed signal sampling circuit, an instantaneous fuel consumption signal sampling circuit and a fuel signal sampling circuit. According to the received instantaneous fuel consumption signal and the vehicle speed signal, the MCU microprocessor calculates the average fuel consumption, and then calculates the continuous driving mileage according to the average fuel consumption and the current remaining fuel amount. The digital display is used for displaying the continuous driving mileage. The average fuel consumption refers to the amount of fuel consumption per hundred kilometers between two refilling; and the remaining fuel amount is obtained by deducting the amount of fuel consumption calculated according to the instantaneous fuel consumption signal from the amount of remaining fuel amount measured right after the refilling.

A heat gun has a body with a support mechanism mounted on the handle. The support mechanism includes at least one arm moveably mounted on the handle and which is capable of moving between a first retracted position and a second extended position. The at least one arm, when it is in its extended position, is capable of co-operating with the body to form a platform upon which the heat gun can rest on a work surface while the nozzle is placed remotely from the work surface.

A mobile communication device includes a receiver, a buffer, a memory, an identifier, and a deleting module. The receiver is used for receiving short message service messages. The buffer is used for storing the short message service messages temporarily. The memory is used for storing a plurality of contact records. The identifier is used for identifying the short message service messages based on the contact records. The deleting module is used for deleting the short message service messages from the buffer if the short message service messages don't pass the identifying action. A mobile communication method is also disclosed.
摘要:
A mobile communication device includes a receiver, a detector, an analyzer, and a deleting module. The receiver is used for receiving short message service messages, and storing the short message service messages in a message record. The detector is used for detecting an occupying space of the short message service messages, and generating a signal if the occupying space is greater than a predetermined volume. The analyzer is used for storing a plurality of message deletion rates of short message service messages and a deletion time, and generating a delete command according to the signal and the message deletion rates or to the signal and the deletion time. The deleting module is used for receiving the delete command, and deleting pending short message service messages according to the delete command. A method for automatically deleting short message service messages from the mobile communication device is also provided.
