A flow discouraging system includes a stator assembly, a rotor assembly, and a plurality of fingers. The stator assembly includes one or more stationary components forming a side wall, the side wall including an annular groove defined by an outer axially-extending surface, an inner axially-extending surface, and a radial surface extending between the outer and inner axially-extending surfaces. The rotor assembly is disposed adjacent to and spaced apart from the stator assembly to form a portion of a cavity and includes an annular rim extending at least partially into the annular groove. The plurality of fingers is disposed in the annular groove and extends from the one or more stationary components the annular rim.

In a first embodiment, an instrument guide includes an elongate guide body extending between a proximal end and a distal end, wherein a portion of the guide body extending proximally from the distal end is generally arcuate. The instrument guide further includes a rigid tip extending generally linearly from the distal end of the guide body. The rigid guide further includes a cannulation formed in the guide body and extending continuously from the proximal end of the guide body to a distal terminus of the tip. The cannulation can be approximately uniform in diameter. The instrument guide further includes a cut-out region, different from the guide body cannulation, extending along at least a portion of an inner radial surface of the arcuate body portion and intersecting the guide body cannulation.

The invention discloses a main shaft double-position positioning device for a rhombic metal mesh knitting machine, belongs to the technical field of rhombic metal mesh knitting machines, and aims to solve the problems of large impact force, inaccurate positioning and difficulty in repair in the existing positioning way. The main shaft double-position positioning device comprises a main shaft sensor system, a main shaft upper-position positioning electromagnet push rod system, a main shaft upper-position positioning electromagnet push rod system bracket, a main shaft low-position positioning electromagnet push rod system, a main shaft lower-position positioning electromagnet push rod system bracket and a molded structure of two interwoven flat spiral steel wires. By adopting the main shaft double-position positioning device for the rhombic metal mesh knitting machine, the problem that impact and vibration are generated since an electromagnet push rod is directly pressed against the radial surface of a cam without any energy dissipation process, the problems that positioning is inaccurate and adjustment is difficult since an electromagnetic brake has an energy dissipation process as well as a positioning function, and the problems of gasification of oil, pitting corrosion of material surfaces and difficulty in replacing sealing parts in the positioning way of a crank slider mechanism are solved.

The invention discloses an LED bulb. The LED bulb comprises an LED light source, a transparent lampshade and a lamp body. The LED light source is fixedly arranged on the lamp body. The transparent lampshade covers the upper portion of the lamp body. An exhaust hole is formed in the transparent lampshade. A light-emitting post comprises a heat conducting post. The heat conducting post is fixedly arranged on the lamp body. The heat conducting post is provided with a first through hole penetrating through the heat conducting post, and second through holes communicated with the first through hole. The LED bulb further comprises a light reflecting cover. The light reflecting cover comprises a barrel. The barrel is arranged in an inner cavity of the transparent lampshade. A plurality of third through holes are formed in the top end of the barrel and in the radial direction of the barrel. The lamp body comprises a lamp holder and a connecting member used for connecting the lamp holder and the LED light source. The connecting member is in an annular shape. Grilling holes surrounding the connecting member are formed in the radial surface of the connecting member. A radiating channel penetrating the outside and the inside of the LED bulb is formed by the grilling holes, an inner cavity of the connecting member, the first through hole, the second through holes, the third through holes, the inner cavity of the transparent lampshade and the exhaust hole. The LED bulb has the advantage of being efficient in radiating.
