TL;DR: In this article, a rotating wheel is used to rotate a rotating container about a first axis of rotation and a rotating shaft is used by a rotating paddle to agitate the contents of the container.
Abstract: A container having a removable lid, a hollow interior for storing contents, and a stirring assembly. The stirring assembly includes a rotatable wheel mounted to an outside portion of the removable lid and a shaft extending into the hollow interior of the container. The rotatable wheel is manually rotatable about a first axis of rotation. The shaft is rotatable by the wheel. When the wheel is rotated about the first axis of rotation, the wheel rotates the shaft about a second axis of rotation. At least one paddle extends outwardly from the shaft into the hollow interior of the container and stirs or agitates the contents of the container when the rotation of the shaft about the second axis of rotation rotates the at least one paddle inside the hollow interior of the container.

TL;DR: This apparatus involves an assembly of a test tube and a paddle insert as mentioned in this paper, where the tube has a frustoconical body and a tapered tip in which a well is a well, having opposed tapered wide flat walls and narrow walls.
Abstract: This apparatus involves an assembly of a test tube and paddle insert The tube has a frustoconical body and a tapered tip in which is a well, having opposed tapered wide flat walls and narrow walls The paddle insert has a long handle integral with a transparent tapered paddle head that is shorter than the tapered well in which the paddle head seats Flexible fingers extend away from the head to frictionally engage the narrow walls of the well and prevent the paddle from falling out of the tube when the tube is inverted or tipped A ridge on the edges of the side walls and the back of the paddle head retains a specimen in a narrow chamber defined between adjacent walls of the tube tip, the paddle head and the ridge for microscopic examination thereof

TL;DR: In this article, a plastic paddle of unitary construction defining a hand grip with a wrist engageable portion at one end, and a blade portion at the opposite end, which blade has a tapered cross sectional shape with flanges defined along its marginal edges to achieve maximum strength from a minimum material, and the paddle material itself being formed of plastic to a uniform thickness for economy in manufacture.

TL;DR: In this article, a dual paddle end effector robot (108) is described, which is capable of parallel processing of workpieces and buffering locations for the workpieces at the respective aligners.
Abstract: A dual paddle end effector robot (108) is disclosed which is capable of parallel processing of workpieces. The end effector (108) includes a lower paddle (250) rotatably coupled to an end of the distal link (106), and an upper paddle (252) rotatably coupled to the lower paddle (250). The lower paddle supports a drive assembly capable of rotating the upper paddle (252) with respect to the lower paddle (250). In one embodiment of the present invention, the dual paddle end effector robot (108) may be used within a wafer sorter to perform parallel processing of workpieces on a pair of aligners within a wafer sorter. In such an embodiment, the robot (100) may first acquire a pair of workpieces from adjacent shelves within the workpiece cassette. After withdrawing from the cassette, the respective paddles on the end effector (108) may fan out and transfer the wafers to the chucks of the respective aligners. After processing of the workpieces on the aligners is complete, the fanned end effector paddles may reacquire the workpieces, the upper paddle (252) may return to its home position located directly over the lower paddle (250), and then return the processed workpieces to their original cassette or to a new cassette. Parallel processing of workpieces in this fashion provides significantly greater throughput than in conventional wafer sorter systems. Throughput may be improved still further by providing buffering locations for the workpieces at the respective aligners.

TL;DR: A sport paddle is disclosed having a circuit board substrate inside the handle which has a sound light circuit, a counter circuit, and a radio circuit as discussed by the authors, which is controlled by a vibration switch which is actuated.
Abstract: A sport paddle is disclosed having a circuit board substrate inside the handle which has a sound light circuit, a counter circuit, and a radio circuit. The opening and closing of the sound light circuit and the counter circuit are controlled by a vibration switch which is actuated. The sound light circuit is connected to an elastic concussion switch to give an amplified reverberatory sound and simultaneously cause a luminous body to illuminate whenever the ball is hit by the paddle. While the elastic concussion switch is connected, the counter circuit is also connected to display on a display screen the aggregated number of times of the ball has been hit. A radio circuit is also provided on the circuit board substrate inside a the handle of the paddle. The opening and closing of the radio circuit is controlled by a switch which allows the user to listen to the broadcasting of a radio station whether or not the paddle is being used in sport.
