The American National Standards Institute (ANSI) Class 150 is a system of dimensional standards for weld neck, threaded, slip-on, lap joint, socket weld and blind flanges. Dimensions for facing, bolts and studs are also included in ANSI Class 150. ANSI Class 150 establishes measures for pipe sizes.
The occipital lobes are the visual processing center of mammalian brains. The primary visual area is Brodmann area 17, located in the interior portion of the occipital lobe at the calcarine sulcus and sometimes continuing onto the surface of the lobe.The lobes' Peristriate regions are the sites for center visuospatial processing, for color discrimination and for discrimination of movement.he front edge of the occipital lobe is separated from the parietal lobe by the Parieto-occipital sulcus. The sides of the lobe merge with the parietal lobes along a vague boundary defined by several lateral occipital gyri, which are separated by lateral occipital sulcus.
The temporal lobe is located on the bottom of the brain below the lateral fissure. This lobe is also the location of the primary auditory cortex, which is important for interpreting the sounds and the language we hear. The occipital lobe is located at the back portion of the brain behind the parietal and temporal lobes.he frontal lobe is located at the front of the central sulcus where it receives information signals from other lobes of the brain. The parietal lobe processes sensory information for cognitive purposes and helps coordinate spatial relations so we can make sense of the world around us.
