TL;DR: In this article, a dual-shaft pan mixer with a rod-shaped vibration generator and a pair of paddle assemblies is described, where the generator is located parallel to the drive shafts.
Abstract: A dual shaft pan mixer comprises a mixing vessel (1) having a first and a second pan section (3 and 4), a pair of paddle assemblies (10) having drive shafts (13) which are disposed horizontally and in paralllel relationship with each other within the mixing vessel (1) and adapted to rotate in mutually opposite directions, and a drive source (20) for synchronously driving the pair of paddle assemblies (10). The mixing vessel (1) includes a substantially triangular space (22) below an area intermediate the first and the second pan section and displaced out of the loci of rotation of the paddle assemblies (10), and also includes a discharge port (5) which is disposed adjacent to the space (22). The mixer also comprises a rod-shaped vibration generator (30) disposed within the space (22) and extending in a direction parallel to the drive shafts (13).

TL;DR: The utility model discloses a portable unmanned aerial vehicle, including fuselage, a 2 -8 horn rotation axis, 4 -16 piece paddle, and a 2-8 paddle rotary part, its characterized in that: every horn one end is fixed on the fuselage through a rotation axis as mentioned in this paper.
Abstract: The utility model discloses a portable unmanned aerial vehicle, including fuselage, a 2 -8 horn rotation axis, a 2 -8 horn, 4 -16 piece paddle, a 2 -8 paddle rotary part, its characterized in that: every horn one end is fixed on the fuselage through a rotation axis, and a 2 -8 horn symmetric distribution is on the fuselage, every horn other end installation paddle rotary part, every paddle tail end is equipped with the round hole, installs two paddles on every paddle rotary part. The utility model discloses to compare the operation simpler with four rotor unmanned aerial vehicle of other brands with equal -volume and performance, takes in more easily, more conveniently carries. It is long wide similar with A4 paper in folding back, and though be go out at ordinary times or go out that the tourism can all follow one's bent put individual knapsack, suitcase and che nei into, also can be lightly freely even holding. The injury of external force is avoided to better protection horn, blade and the foot rest of folding state ability simultaneously.

TL;DR: In this article, a high-pressure high-temperature liquid viscosity measuring device and method is presented, which consists of a driving motor, a torque sensor, an induced magnetism barrel, a rotating shaft and a stirring paddle.
Abstract: The invention discloses a high-pressure high-temperature liquid viscosity measuring device and method. The measuring device comprises a high-pressure high-temperature system and a measuring system, wherein the measuring system comprises a driving motor, a torque sensor, a driving magnetic barrel, an induced magnetism barrel, a rotating shaft and a stirring paddle; one end of the torque sensor is connected with the driving motor, the other end of the torque sensor is connected with the driving magnetic barrel, and the driving magnetic barrel rotates along the torque sensor; the induced magnetism barrel is positioned in the driving magnetic barrel and can rotate along the driving magnetic barrel under the magnetic action; one end of the rotating shaft is connected with one end, which is far from the torque sensor, of the induced magnetism barrel, the other end of the rotating shaft is connected with the stirring paddle, and a part of the rotating shaft is positioned in the high-pressure high-temperature system; the stirring paddle is positioned in the high-pressure high-temperature system, and the stirring paddle comprises multiple blades which are symmetrically arranged around the rotating shaft. The measuring device provided by the invention can accurately detect the liquid viscosity under a high-pressure high-temperature condition.
