An optical fiber polishing arm positioning assembly for use with an optical fiber polisher, the optical fiber polisher including a first pivot connection interconnecting a base and a proximal end of an arm assembly, comprises a positioning member and an actuator. The positioning member is configured and arranged to be operatively connected to the arm assembly, and the actuator is configured and arranged to move the positioning member thereby moving the arm assembly about the first pivot connection to vary positions of the arm assembly relative to the base.

An abrading device includes a funnel and an outlet orifice disposed within the funnel for passage of abrasive material, where a distance between the outlet orifice and a bottom end of the funnel is adjustable. An exhaust tube is coupled to the funnel for withdrawal of spent abrasive material from the funnel.

A simple and automatic fiber cleaver, comprises an upper cover and a base, wherein the upper cover and the base are pivotally connected through a rotating shaft; the base comprises a framework moving space and a guide rail framework; the guide rail framework moves in the framework moving space and cuts fibers in the moving process; the guide rail framework comprises a positioning pin and an elastic device; the positioning pin is embedded and movably connected with the guide rail framework; one end of the elastic device is fixedly connected with the positioning pin; and the other end of the elastic device is fixedly connected with the guide rail framework; and the elastic device can drive the positioning pin to move up and down and clamp into the base or release from the base; the guide rail framework and the base respectively comprise magnetic devices with the same magnetism and/or different magnetism, and the attraction or repulsion action of the magnetic devices causes the guide rail framework to move and cut fibers in the moving process.

Devices, systems and methods for the recycling and recovery of carpet are disclosed herein, including devices, systems and methods for disassembling or deconstructing carpet into the various components that make up the carpet, by abrasive removal and separation of the components.

A cooking appliance light for particular for use in a cooking appliance such as an oven, microwave, or steam cooker, wherein the cooking appliance contains a cooking chamber with walls and a door, which has at least one LED light source that can be secured in a mount outside the cooking chamber, and a fiber optic rod, which extends from the mount along its longitudinal axis at least partially into the cooking chamber, wherein the fiber optic rod has a light entry surface where light from the light source enters the fiber optic rod, and a light emission surface where at least a part of the light is emitted into the interior of the cooking appliance, wherein a decoupling structure that deflects light is formed in the fiber optic rod, with which light is directed through the light emission surface into the interior of the cooking appliance.

Provided is an optical fiber ferrule polishing jig capable of fixing an optical fiber ferrule and releasing the optical fiber ferrule. An optical fiber ferrule polishing jig 10A has; a base 12a having insertion holes 20 into which optical fiber ferrules 51 can be detachably inserted; pivoting rods 13 which are adjacent to the insertion holes 20 of the base 12a and rotatable around lower end portions 36; fixing pieces 14a installed in installation recesses 19a formed in the base 12a to fix the optical fiber ferrules 51 with respect to the insertion holes 20 by being moved as the rods are pivoted; and a plurality of coil springs 15a installed in the installation recesses 19a to bias the fixing pieces 14a so as to release fixing of the optical fiber ferrules 51 with respect to the insertion holes 20.

The invention relates to a brush grinding head (1) for a grinding machine (2), comprising an essentially roller-shaped carrier (3) and grinding lamellae (4), wherein the grinding lamellae (4) are arranged peripherally on the carrier (3) and are composed at least of, in particular bundled brushes (5) and an essentially strip-shaped grinding element (6) which is arranged adjacent thereto. The grinding element (6) comprises at least one abrasive layer (7) and an abrasive-free layer (8) which can be compressed while retaining its shape and is designed in such a way that a grinding fluid (27), in particular water, can be stored in it.
