Linear variable spectral filter changes wavelength along the length of the filter. When the filters are used with a slit on the entrance side, broadening the slit leads to a wider transmission curve and a reduction of the maximum transmittance. It transforms the incident spectral distribution into a spatial distribution. It converts spectral information from incoming light into a spatial distribution recorded by the detector array.

The linear welding process is suitable to weld 0.1mm and above stainless steel sheets into thin wall tubes and pipes of up to 500mm length. Typically, the linear welding system consists of a hydraulic cylinder and power pack for torch motion, pneumatic cylinder, or spring loaded clamps to hold the job with suitable holder. This welding process is used to weld any cylindrical jobs, strips, sheets, where a precise linear fusion weld is required.

Lined Chute is designed to transfer the material from the skip to the 10-tons capacity discharge bin. The chute width is determined by the length and arrangement of the spillway crest, the total energy in the water and the economical relation between the width & the height of the sidewalls of the chute.
