Abstract: Apparatus for drilling holes in a formation utilizing pulsed jets of charge material. A housing encloses means for generating pulsed jets of, for example, liquid charge material. One or more acceleration bores extend out the housing in a conical pattern. One or more longitudinal grooves are included in the housing, and means are provided for impelling spent charge material, formation chips, mud, etc. from the hole and out through the longitudinal grooves. A single acceleration bore can have one or more outlet bores angled therefrom to cause a rotational force in the housing in response to expelling of pulsed jets of charge material out the outlet bores. The housing can be made of a first portion with the acceleration bore therein and a nozzle portion with the outlet bores therein and rotatably coupled to the first portion so that only the nozzle portion rotates in response to expelling of pulsed jets. Smoothing tips can extend from the housing to smooth the hole as the housing rotates.

Abstract: Apparatus for forming pulsed jets of liquid. A movable cylinder cooperates with a nozzle block to define a compressible charge chamber into which water, or other liquid flows. A latch retains the cylinder. When it is desired to generate a pulse, the latch is released, allowing the cylinder to move and expand the charge chamber, thereby drawing from the nozzle any liquid remaining from the preceding pulsed jet of liquid. A piston is then actuated to impact on the cylinder, compressing the chamber and expelling the charge through the nozzle as a pulsed liquid jet. The cylinder is moved so that the charge chamber is compressed and the latch again retains the device in this condition. A floating check valve permits escape of air from the chamber during filling with water.

Abstract: Apparatus for forming pulsed jets of liquid. A movable cylinder cooperates with a nozzle block to define a compressible charge chamber. A piston within the nozzle block is movable between a firing position, in which it completes the nozzle discharge opening from the charge chamber and a loading position, in which it permits passage of gas to the nozzle discharge opening, thereby removing any liquid remaining therein from the preceding liquid jet pulse. To generate a charge, the piston is moved to the loading position, following which the discharge opening is blown dry and charge material is applied to the charge chamber. An actuating piston is actuated to impact on the cylinder compressing the chamber and expelling the charge through the nozzle as a pulsed liquid jet. A floating check valve permits removal of air entrapped within the charge chamber.

Abstract: Self-calibrating apparatus for determining the radiation scattering properties of a fluid. Radiation from a first source passes through the fluid in a first straight line path to a first radiation detector. Radiation from a second source passes through the fluid to a second radiation detector in a second straight line path intersecting the first path at the scattering angle of interest. The radiation detector outputs are combined to give the scattering coefficient.

Abstract: Apparatus for producing a high velocity jet pulse of liquid suitable for cutting or fracturing such materials as rock, metal, concrete and wood. A barrel is provided with a bore that intersects a rotatable valve which in a first position receives a liquid or gel charge and which in a second position is colinear with the barrel bore. Compressed gas expells the charge from the barrel through a nozzle to form a pulsed jet of liquid. Means can be provided for positioning the nozzle adjacent an extrusion as it issues from an extruder, permitting on-line cutting of the extrusion and for rotating the nozzle about a horizontal axis to permit operation at the optimum angle of cut.

Abstract: Apparatus for forming pulsed jets of liquid. A pressure cylinder cooperates with a barrel inlet end to define a charge chamber. With the pressure cylinder in its normal position, the barrel inlet opening is blocked. Upon actuation of the device, the pressure cylinder is forced toward the barrel inlet end, applying pressure to charge material within the charge chamber, until the barrel outlet opening is unblocked and the pressurized charge material is expelled through the barrel as a pulsed jet.
