High-efficiency double-shaft stirring mixer

Abstract: The utility model relates to a stirring and mixing machine. The utility model is used for various solids or liquid materials of chemical products, foods, drugs, fodders, minerals, concrete, etc. The utility model uses a double-shaft structure which is sheathed by a solid shaft and a hollow shaft. A machine shell forms an inverse triangle shape. The interior of the machine shell is provided with a forward and backward stirring paddle. The machine shell is also provided with a material feeding hopper, a material discharge opening, etc. The forward and backward stirring paddle drives a forward and backward rotation shaft to rotate by an electric motor through a gear wheel. The forward and backward rotation shaft drives a hanging arm and the stirring paddle. The utility model has the advantages of fast mixing speed, uniformity, wide application, convenient operation, little energy consumption, convenient maintenance, and easy washing after used.

Pulley type potential generator

Abstract: The invention relates to a pulley type potential generator, which comprises a pulley, a cam, and a plurality of blades These blades are uniformly disposed outside the pulley in the circular direction Each blade comprises a sub paddle and a main paddle, wherein the sub paddle is longer, while the main paddle is relatively shorter One end of the main paddle is rotatably attached to the outer wall of the pulley through a pin roll, and the other end of the main paddle is hinged to a sub paddle through a rotation shaft The cam disposed inside the pulley is attached to every main paddle througha mandrel mechanism whose the number is the same with the number of the main paddle Each mandrel mechanism comprises a mandrel and an offsetting spring A pulley abutting against the cam is attachedto the inner end of the mandrel A cross shaft is disposed on the outer end of the mandrel in a manner that it is embedded into a sliding slot on the inner surface of the main paddle, and slidingly engaged with the sliding slot By adopting a changeable blade structure, the pulley type potential generator is capable of power generation by fully utilizing hydraulic power, and the conversion ratio between the hydraulic power and the electric power is very high

Sloping table sliding puck game

Abstract: A sloping table sliding puck game and method for playing the same. A table having a substantially frictionless is elevated at an angle. A rebounding device is placed at one end of the table. A game player at the other end of the table projects a puck along the top surface of the table toward targets adjacent the rebounding device with a hand paddle. The table is sloped to force the puck to return to the game player. Optical sensors detect when the puck passes over the targets. A chute is located behind the rebounding device. When the game is over the rebounding device drops permitting the puck to enter the chute. The chute is constructed to return the puck to the player at the other end of the table from the rebounding device before the start of the next game.

Rigidity and flexibility combined stirring paddle

Abstract: The invention discloses a rigidity and flexibility combined stirring paddle. The rigidity and flexibility combined stirring paddle is composed of rigid paddle blades and flexible sheets, wherein the rigid paddle blades are fixedly connected with a stirring shaft; the flexible sheets are connected with the rigid paddle blades; the rigid paddle blades provided by the invention at least are in upper and lower two layers; the connection mode of the flexible sheets and the rigid paddle blades is that the upper ends of the flexible sheets are connected to the rigid paddle blades in the upper layer at an overlapped state, and the lower ends of the flexible sheets are connected to the rigid paddle blades in the lower layer; and the lengths of non-overlapped parts of the flexible sheets and the rigid paddle blades at upper layer and lower layer are 1.2-1.5 times the distance from the lower edges of the corresponding rigid paddle blades at the upper layer and the upper edges of the rigid paddle blades at the lower layer. Compared with the prior art, according to the invention, the stirring efficiency can be improved reliably, and the device cost can be saved.

Fluid rotor angular rate sensor and three-axis angular rate sensor utilizing the smae

Abstract: Fluid rotor angular rate sensor with a single sensitive axis having means forming a substantially continuous passageway and having a fluid mass in the passage serving as a fluid rotor. A paddle member is disposed in the passageway and inhibits movement of the fluid rotor in the passage. Means is for provided for sensing the position of the paddle member in the passageway. Electrical means is connected to the means for sensing the position of the paddle member and for applying a restoring force directly to the paddle member which is proportional to the force necessary to accelerate the fluid rotor as the rate sensor is accelerated about the single sensitive axis. The electrical means produces a signal proportional to the angular acceleration and includes means for integrating the signal to provide an output proportional to the rate of turn of the rate sensor about the single sensitive axis. In the three-axis angular rate sensor, three of the single axis angular rate sensors are mounted on X, Y and Z axes.
