A torque detection device includes a base, a load sensing member, a push member, a transmission module, and a drive module. The push member has a first extension wall and a second extension wall. The transmission module includes two adjustable transmission sets each including a torque transmission part. The torque transmission part respectively rests on the first extension wall and the second extension wall of the push member. The torque transmission part of the transmission module applies a force to push and press the push member reciprocatingly. The push member transmits the force of the torque transmission part to the load sensing member which cooperates with an electronic device to measure the maximum static friction torque of a detected workpiece.

The present invention provides an additive for tin stripping, comprising 0.1 to 20 wt % of copper corrosion inhibitor and 0.1 to 20 wt % of nickel corrosion inhibitor; wherein said weight percentage is based on the total weight of said additive. The present additive can be used with nitric acid conventionally used for metal-stripping for not only reducing the usage of nitric acid but also improving the efficiency of tin stripping. The present invention also provides a method for Tin recycle and a reaction tank for metal recycle. Both of them are favorable for satisfying the needs of metal recycle (especially, tin recycle) in the field.

Tin stripping method

The present invention provides a metal stripping additive, composition containing the same, and method for stripping metal by using the composition. The metal stripping additive comprises a phosphate, a carbonate, and a component selected from at least one of citric acid or a derivative thereof, oxalate or a derivative thereof, malate or a derivative thereof. The metal stripping additive is used with nitric acid as the metal stripping composition of the present invention. The present method has advantages of being capable of stripping various metals, low corrosion, low toxicity, and being applicable under ambient temperature.

A transversely movable hinge is mounted between a base and a cover of a folding device and has a moving assembly. The moving assembly is connected to an expansion device via a linking rod. Therefore, when the folding device is opened, the expansion device is driven to extend and is convenient for users. When the folding device is closed, the expansion device is driven to retract for saving space.

A hinge includes a first leaf assembly with a first leaf and two barrels. A pintle has a cylindrical part extending through a first of the barrels and a non-cylindrical shaft extending through the second barrel. A second leaf is mounted on the pintle. A collar with a non-circular opening is provided outside the shaft. A resilient member is provided between the cylindrical part and the collar. Two channels are defined at a side of the collar facing the second barrel for alternately receiving at least one lug formed on the second barrel. Whereby, when the pintle is turned about the barrels, the first leaf can be positioned at multiple points about the second leaf.

Hinge

A hinge for a notebook computer is composed of a first seat, a second seat and an axle. The first seat is mounted on a monitor, and the second seat is mounted on a body. The axle is securely mounted on the first seat and pivotally mounted on the second seat. Two sleeves are provided outside the axle and engaged with each other in a closed status. The first sleeve has two lugs received in a channel defined in the second sleeve. The second sleeve has two protrusive portions respectively formed at two sides of the channel, and two cambered surfaces formed between the channel and the protrusive portion. When a user lowers the monitor to a position that the lugs enter into the cambered surfaces, the monitor can automatically descend under the effect of gravity and the force of a resilient member.

A hinge bracket has a positioning disk adapted to be abutted to one side of the leg of the frame and having a first cutout and a second cutout peripherally defined around the positioning disk and a pad sandwiched between the positioning disk and one of the second leaf springs. The pad has a finger alternately corresponding to the first cutout and the second cutout so that the frame is able to be supported at a first position or the frame is able to be extended at a second position to be in parallel with the base to minimize space taken when stored or transported.
