TL;DR: In this article, a multifunctional dryer system for cake or crystalline easily oxidized products or preparations needing soft water or organic solvents for filtration washing, sterilization, solvent recovery, crushing, granulation and vacuum drying at terminals during production process in the industries of biology, pharmacy, chemical engineering and the like.
Abstract: The invention relates to a multifunctional dryer system, which is applicable to drying production of cake or crystalline easily oxidized products or preparations needing soft water or organic solvents for filtration washing, sterilization, solvent recovery, crushing, granulation and vacuum drying at terminals during production process in the industries of biology, pharmacy, chemical engineering and the like A crushing blade for crushing materials, a first paddle and a second paddle are arranged on a rotating shaft of a stirrer of the system and are distributed from top to bottom, and the first paddle and the second paddle are used for turning over and mixing the materials and are suitable for turning over the materials upwards and downwards respectively, so that the materials form vortex revolving around the rotating shaft between the first paddle and the second paddle Further, the materials rotate along with the vortex while rotating around the rotating shaft, the running distance of the materials is lengthened, turning-over times are increased, the purity of washed materials is improved, drying efficiency in the drying process is increased, and a caking layer can be broken during filtration so that the materials are filtered sufficiently and thoroughly

TL;DR: The paddle method is biased by a kinesthetic deficiency, namely a rotational problem of the wrist that can be corrected by means of specific training.
Abstract: We tested the validity of the paddle method for measuring both the kinesthetic and visual-kinesthetic perception of inclination. In three conditions, subjects performed three different tasks: (1) rotating a manual paddle to a set of verbally given inclinations (blindfolded subjects), (2) rotating a manual paddle to the same set of verbally given inclinations after specific kinesthetic training (blindfolded subjects), and (3) rotating the paddle to a set of fixed visual inclinations after the kinesthetic training. The results showed a high degree of accuracy and precision in the second and third task but not in the first one. When subjects were asked to rotate a manual paddle to a set of verbally given inclinations, they used three main anchors (0°, 45°, 90°). Furthermore, the paddle method is biased by a kinesthetic deficiency, namely a rotational problem of the wrist that can be corrected by means of specific training.

TL;DR: This paper proposes a novel eccentric paddle mechanism (ePaddle) which exhibits high environmental adaptability and can achieve six major types of gait, such as wheel-like rolling, two legged walking gaits, wheel-paddle-integrated rolling, and aquatic paddling gaits to access soft terrain.
Abstract: The use of rescue robots in disaster response has become increasingly common, but few of them can operate on harsh amphibious terrain, especially on soft terrain. To access such challenging environments, we have proposed a novel eccentric paddle mechanism (ePaddle) which exhibits high environmental adaptability and can achieve six major types of gait, such as wheel-like rolling, two legged walking gaits, wheel-paddle-integrated rolling, and aquatic paddling gaits. In this paper, we present the details of the paddle trajectory generation method for ePaddle to access soft terrain. On such conditions, the paddle can operate as a lug to generate additional pull and lift forces that improve traction performance and prevent wheel sinkage than using wheel-like rolling. We adopt the passive pressure theory to model the pull and lift forces acting on the paddle; these forces are determined by soil parameters and the inclination angle, sinkage length, and moving direction angle of the paddle. Based on this model, we propose a motion planning strategy to control the inclination angle and protruded length of the paddle to generate required pull and lift forces and weaken any fluctuations in them. Then, we verify the effectiveness of our proposed method by using simulations.

TL;DR: A paddle wheel feeder includes a paddle wheel having a foam hub with at least three blades molded therein and is mounted to a shaft having a Geneva mechanism attached thereto which causes the paddle wheel to stop just before one of the blades contacts the top sheet in a stack as discussed by the authors.
Abstract: A paddle wheel feeder includes a paddle wheel having a foam hub with at least three blades molded therein. The paddle wheel is mounted to be rotatably driven by a shaft having a Geneva mechanism attached thereto which causes the paddle wheel to stop just before one of the blades contacts the top sheet in a stack and then accelerate to drive the sheet forward. For normal force optimization, internal springs are located inside each paddle of the wheel is one embodiment and a thick bladed foam paddle wheel is utilized in another embodiment with each blade having a coating of high friction material.
