Methods and apparatus are disclosed for forming a liquid spray mixture containing accurately proportionated amounts of viscous coating concentrate and compressed fluid diluent such as carbon dioxide. The proportionation is accomplished by passing the fluid diluent through two sets of flow restrictors under the same pressure drops to form two proportioned flows of diluent. One diluent flow is conve...

The device is provided with independent range finding means 10-13 and movement sensing means 14-16, the sensing means generating output signals in response to the detection of an object, which output signals provide information as to the range and size of the object detected, and a comparator means for comparing the output signal from the sensing means with a pre-set threshold level. The range fin...

A reagent delivery system comprises an axial hub passing through the center of two equal-diameter, spaced apart discs, wherein the hub and discs are positioned in a sleeve such that an annular reagent chamber is provided. When the sleeve is moved in either an up or down axial direction the so-formed chamber is opened and the reagent is released. Such a regent delivery system is particularly useful...
