Abstract: This is a device for a bore wiping, self-lubricating ramrod used for muzzle loading gun barrels. The device consists of a bullet jag with two 0-rings, and a center hole to allow the lubricant to get into the bore. As the jag is passed down the bore a small amount of lubricant is released into the bore. The first 0-ring stops the lubricant from leaving the bore, and the second 0-ring wipes the bore clean when the ramrod is pulled out of the bore. The ramrod may be made in different diameters to accommodate different caliber muzzleloaders. The shooter uses the same ramrod for lubing and loading the weapon with the same pass down the barrel.

Abstract: A system and method for automatically collimating X-rays. A digital X-ray system (100) includes a generator (108), a sensor unit (110), a control station (112), and a preview monitor (114). The generator (108) generates X-ray radiation that is captured by the sensor unit (110) as a digital image and transmitted to the control station (112). The captured image is displayed on the preview monitor (114). The generator (108) includes a collimator (212) that collimates the generated radiation into a primary beam of X-rays. The size and shape of the primary beam can be adjusted by modifying collimation parameters. A short duration beam of X-rays is generated by the generator (108) and captured (414) by the sensor unit (110). This step is repeated as necessary or desired. The resulting digital images are analyzed (418) by the control station (112) to calculate a calibration coefficient. Another short duration beam of X-rays is generated and a reference image is captured (514).
