摘要： An apparatus and method for monitoring and/or controlling cryogenic cooling by measuring the opacity of the vapor cloud (113) generated from a cryogenic cooling device (112). The opacity is determined by measuring the reduction in intensity of a light beam (127) passed through the vapor cloud (113). The opacity measurements are used to control an operating parameter of the system, such as the cooling rate of the cryogenic cooling device (112). The opacity measurements may be normalized to compensate for variables, other than temperature of the workpiece (119) and cooling rate, which may affect the opacity of the vapor cloud (113).
摘要翻译： 一种用于通过测量由低温冷却装置（112）产生的蒸汽云（113）的不透明度来监测和/或控制低温冷却的装置和方法。 通过测量通过蒸气云（113）的光束（127）的强度的降低来确定不透明度。 不透明度测量用于控制系统的操作参数，例如低温冷却装置（112）的冷却速率。 不透明度测量可以归一化以补偿除了工件温度（119）和冷却速率之外的变量，这可能影响蒸气云（113）的不透明度。

摘要： Use of a shrouding gas to combine with and protect a turbulent gas jet issuing from an orifice enables control of a gas jet stream composition downstream from the orifice. The natural aspiration rate of the gas jet is used to determine the flowrate of shrouding gas which is introduced around the gas jet in a soft gas cushion which does not disrupt the flow pattern of the gas jet but instead is entrained into the jet stream to the exclusion of ambient gases in the atmosphere. Preferably shrouding gas is replaced at least at the rate at which it is entrained. Apparatus for this process uses a porous shroud, preferably of metal foam, through which shrouding gas flows evenly around the gas jet as it issues from a nozzle orifice. Provision for tangential entry of shrouding gas into a manifold which feeds the porous shroud prevents the shrouding gas from impinging upon the porous shroud and causing uneven flow around the gas jet.
