Abstract: A carbon deposition eliminator for installation in the exhaust pipe of a motor vehicle to guide exhaust gas through the exhaust pipe and to eliminate deposition of carbon in the inside wall of the exhaust pipe is disclosed to have a tubular body, which defines a gas input port at one end and a tapered inside wall gradually reducing from the gas input port toward the other end of the tubular body for accelerating the flowing speed of exhaust gas, and a tubular neck, which defines an exhaust port at one end remote from the tubular body and a straight inside wall connected between the narrowest end of the tapered inside wall and the exhaust port.

Abstract: A steering wheel lock includes a stop bar, an extension rod member, a lock cylinder for locking the extension rod member to the stop bar, two locating plates respectively fastened to the stop bar and the extension rod member, two coupling plates horizontally angle-adjustably fastened to the locating plates, and two hook members respectively pivotally coupled to the coupling plates and locked by a respective locking mechanism for securing the locating plates to a motor vehicle's steering wheel.

Abstract: A vehicle steering wheel lock comprises a first plate and a second plate that can be engaged onto a steering wheel of a vehicle for protecting the vehicle or an air bag in the steering wheel from being stolen. The first plate and the second plate can be engaged with each other in a manner having a smaller overall area for convenient storage.

Abstract: A device for turning long members includes two spaced receiving discs each including a first half disc and a second half disc. Each of the first half discs and the second half discs includes a diametrical side and a semi-circle periphery. The diametrical side of each first half disc having a first cutout defined therein, while the diametrical side of each second half disc having a second cutout defined therein, the first cutout and the second cutout together defining a compartment adapted to be fittingly extended through by a long member. The semi-circle periphery of each of the first half discs and the second discs including a plurality of spaced rectilinear sections. Each first half disc and an associated second half disc include aligned slots when assembled, and further comprises fastening members extended through the aligned slots to secure the first half disc and the associated second half disc together.

Abstract: A device for turning long members includes two spaced bases each including two spaced vertical plates mounted on a top side thereof. A number of wheels are rotatably, mounted between the plates and located on a common circumference. Each wheel includes an annular groove defined therein. Two receiving discs are respectively, rotatably held by the wheels on the associated bases. Each receiving disc includes a first half disc and a second half disc which are releasably assembled together. The first half disc includes a peripheral edge received in the grooves of the associated wheels. Each of the first half disc and the second half disc includes a cutout for receiving a long member.
