Detachable disperse agitator paddle

Abstract: A detachable disperse agitator paddle comprises an agitating shaft and a paddle The paddle in a straight line shape is formed by fixing two blades onto a cylinder; a shaft head of the agitating shaft is square and provided with a through hole; a square hole with an upward opening is arranged in the center of a shaft sleeve; the lateral wall of the shaft sleeve is provided with two through holes; the square shaft head is placed in the square hole; and the agitating shaft is connected with the shaft sleeve by the aid of a pin penetrating through the three through holes The lateral wall of the tail of the pin is provided with a through hole, and the portion with the through hole at the tail of the pin is placed outside the shaft sleeve A rotary shaft penetrates through the tail through hole of the pin, and two ends of the rotary shaft, the pin, the agitating shaft and the shaft sleeve are fixedly positioned by a lock sheet The detachable disperse agitator paddle is simple in structure, convenient in installation and detachment, wide in applicability and capable of achieving effective disperse effect without cutting apart an integral slurry barrel

Semiconductor package with chamfered corners and method of manufacturing the same

Abstract: A semiconductor package comprising a die paddle defining multiple corners and opposed first and second surfaces. At least one set of leads extends at least partially about the die paddle in spaced relation thereto. Each of the leads has opposed first and second surfaces. Attached to and extending from one of the corners of the die paddle is at least one tie bar which itself has opposed first and second surfaces and at least one aperture disposed therein and extending between the first and second surfaces thereof. Attached to the first surface of the die paddle is a semiconductor die which is electrically connected to at least one of the leads. A package body at least partially covers the die paddle, the leads, the tie bar and the semiconductor die such that the second surfaces of the leads are exposed in and substantially flush with a common exterior surface of the package body, and a portion of the package body extends through the aperture of the tie bar.

Simulation analysis of paddling motions in a single kayak: Development of a comprehensive dynamic model of a paddler, paddle and hull

Dynamic mixer for dental materials has at least two paddles in succession at the mixer on the side towards the chamber closure which do not strip the chamber walls

Abstract: The dynamic mixing appliance, especially for viscose dental materials, has a mixer (3) within the chamber (1) fitted with at least two mixing paddles (5,6) in succession along the longitudinal line, on the side towards the closure (2). The paddles do not strip material from the chamber wall. They each have axial passages, offset from each other so that the passages in one paddle are covered by the solid surfaces of the other paddle. The closure (2) is fitted with an inner sleeve (4) to support the free end of the mixer (3), extending longitudinally almost to the level of the first paddle (5).
