Abstract: The machine comprises an automotive vehicle (1) and at least one grinding carriage (2). During the grinding operation of the rail, the automotive vehicle (1) is standing still, immobile with respect to the railroad track, whereas the grinding carriage (2) displaces itself reciprocally along the track. The distance between the the carraige (2) and the vehicle (1) is thus variable.

Abstract: A method of microdeburring a selected portion of bore in a workpiece with a jet of abrasive gas is provided that is particularly applicable to the removal of microburrs at the interface between the timing and metering spill ports in a fuel injector metering barrel and the plunger bore. In the method, the nozzle that emits the abrasive gas is first inserted in and aligned with the bore so that the jet is focused on the microburrs at the interface. The nozzle is then actuated for a time period long enough for the jet to remove the microburrs from the bore, but insufficient for the jet to cause unwanted radiusing of the bore at the interface that could degrade the timing characteristics of the fuel injector. The method also includes the step of interposing a shield within the metering barrel to mask off the finished surface of the barrel from unwanted abrasion.

Abstract: A radial grip remote control for the operation of abrasive blast machines. The handle of the grip is permanently attached to a linear bearing. The bearing utilizes the abrasive blast hose as a journal, and may be rotated manually by adjusting the radial position of the handle. The inside diameter of the bearing is adjustable. The adjustment is intended to allow the bearing to rotate freely about its journal (hose), and to cause seizure of the bearing to this journal when the hose is pressurized. The steel handle acts as a protective housing for a positive shut-off type valve which is internally installed. The remote control is designed to be ergonomically accommodating and to increase the safety of abrasive blasting operations. The base of the handle comprises a female connecting socket for adaptation to automated or remotely operated abrasive blast systems.

Abstract: A radial locator is carried by the bed of a cam lobe grinding machine proximate the workpiece chuck. An initial locating pin is carried by the chuck to sense a rough locating hole in a sprocket carried by a cam shaft to be disposed in the chuck to have its cam lobes ground. A timing tooth is provided on the sprocket in proper proximity to the rough locating hole and for coaction with complimentary locating teeth carried by a rockable locating arm of the radial locator. An actuating arm carries the locating arm for movement between an at rest disposition and a rocked disposition wherein the locator teeth coact with the timing tooth to rotate the sprocket, cam shaft and cam lobes to a final position for proper grinding of the cam lobes. A rotary actuator moves the actuating arm an locating arm between their respective dispositions.

The flow of water is first controlled by a regulator located in a water intake but may instantly be started and stopped by the finger of the operator. The water is delivered onto the sanding surface by perforations located under the wet sanding block.

Abstract: An apparatus for grinding a metallic workpiece rotating about and centered on an axis and having an annular surface also centered on the workpiece axis has a tool support radially offset from the workpiece axis, continuously rotating about a support axis radially offset from and substantially parallel to the workpiece axis, and having an forwardly axially directed front support face, and an annular grinding tool engaging the workpiece surface, centered on a respective tool axis, and having an axially backwardly directed rear tool face. The tool face is resiliently supported on the support face annularly all around the support and tool axes so that the tool axis can rock relative to the support axis.

Abstract: A rotating cutting blade and its drive motor are mounted on a wheeled support platform. The blade extends through a skid plate depending from the platform, in order to cut the concrete below the skid plate. The slot in the skid plate has its ends configured to fit within predetermined distances of the corresponding ends of cutting segments on the cutting blade. The cutting segments are configured to have a generally inverted "T" configuration in which a central cutting segment extends radially outward from two cutting segments located on opposite sides of the central segment. The exterior edges of the cutting segments may be square or rounded. The juncture between the central and shoulder segments may be square or rounded. The concrete is advantageously cut before it hardens to 1200 psi, without the use of an added lubricant, or above that hardness with lubricant if the cutting blade is supported within a sufficiently close distance by a skid plate.

In a preferred version of the invention, the pad texture consists of a macrotexture produced prior to use and a microtexture which is produced by abrasion by a multiplicity of small abrasive points at a regular selected interval during the use of the pad.

Abstract: A cutting machine for a railroad rail performs clamping by use of a screw to fasten a catch arm onto a gauge which indicates a cutting position and is fastened onto a railroad rail. The catch frame is connected to a main body block via slide shafts, and a rotating grinding disk saw, driven by an engine mounted on the main body block, is rocked by working a stroke handle to smoothly raise and lower the rotating grinding disk saw within a cut opening to cut the railroad rail crosswise. By varying the cut of the rotating grinding disk saw, frictional resistance to cutting is reduced and the generation of frictional heat is prevented, permitting use of a small-scale engine and improving the accuracy of the cut.
