Abstract: A disc brake which is particularly designed for arcuate travel of less than 360 degrees has sector shaped segments, i.e. segments which are not complete circles and which are interleaved into a disc pack of multiple layers, wherein some layers of the disc pack each consist of a single disc segment which is less than a complete circle. Some segments are rotatable about an axis and others are stationary and have friction brake material carried on them at a position remote from the axis of rotation.

Abstract: A lateral manifold (10) for a fluid sensor (100) enables the fluid sensor (100) to sample multiple locations (70) and distinguish which location is being sampled. The design minimizes space, has no unused plumbing, allows for multiple sample tubes (51-55) to provide continuous flow, and enables a method for collecting samples from multiple locations (70).

Abstract: A disc brake which is particularly designed for arcuate travel of less than 360 degrees has pie shaped segments, i.e. segments which are not complete circles which are interleaved. Some segments are rotatable about an axis and others are stationary and have friction brake material carried on them at a position remote from the axis of rotation.
