TLDR
In this paper, a flow density transducer and a pressure or velocity transducers are used to measure flow velocity during air blast peening with predetermined desired values, and the operation of the apparatus is automatically adjusted by adjustment of flow density and/or flow velocity to maintain these parameters at desired values.
Abstract
Air blast peening equipment includes a flow density transducer and a pressure or velocity transducer for measuring flow velocity. Measured values are compared during peening with predetermined desired values. Operation of the apparatus is automatically adjusted, if necessary, by adjustment of flow density and/or flow velocity to maintain these parameters at desired values.

Method and apparatus for drilling small diameter holes in fragile material with high velocity liquid jet

TL;DR: In this paper, an abrasive-jet drilling system is described for small diameter holes in fragile materials of the type which tend to crack when impacted by such jets. But the system employs a drilling jet formed from a high pressure liquid whose pressurization varies with time during the drilling process.

Fluid jet cutting system and method

TL;DR: In this paper, a fluid jet cutting system is proposed to make desired quality cuts in a solid material such as stone, granite, steel and/or marble, the system having a positioning assembly which positions the solid material in a cuttable orientation over a fluid reservoir and at least one fluid jet generator which directs a concentrated, high pressure stream of fluid through a nozzle at the material such that the solid materials is cut by the high pressure streams of fluid.
