A Bio-Inspired Contrast Adaptation Model and its Application for Automatic Lane Marks Detection

An improvement is provided in a process and apparatus for in-line slush making, for use in, for example, concrete cooling. The improvement comprises connecting the inlet used to convey liquid such as water to the manifold section of the lance so that its longitudinal axis forms an acute angle with respect to the longitudinal axis of the inlet for introducing a cryogen into the lance. This improvement substantially eliminates failure to properly make slush due to a build-up of ice within the means used to control the flow of cryogen to the system. Additional improvements to the apparatus comprise substantially aligning the sealed head of the manifold with the longitudinal axis of the inlet for conveying the liquid to the lance to eliminate and to prevent freeze-up of the liquid in the dead space found in the "T" lance design of the prior art.
