    摘要： A method and a rapper device for cleaning a heat exchange surface in a pressure vessel. The rapper device comprises a striker rod which has one end contacting the heat exchange surface in the pressure vessel and one end projecting out of the pressure vessel via a passage opening. The rapper device also comprises an impacting device for impacting the projecting end of the striker rod. A section of the striker rod is slideably supported in a pressure chamber adjacent the passage opening. The pressure chamber is connected to a sealing gas supply maintaining the pressure in the pressure chamber at a higher level than the pressure in the pressure vessel. A bellows defines a pressure chamber around at least a section of the striker rod.

    摘要： A blade for mounting to a scraped surface heat exchanger drive shaft by pivotal connection with a mounting pin has a blade body having a first side and a second side, and a scraper edge and a hinge edge. At least one mounting hole extends through the blade body generally proximate at the hinge edge. An L-shaped locking track protrudes into the first set of the blade, having an entry track extending from the hinge edge and an intermediate track extending from the entry track to the mounting hole. An L-shaped locking track also protruding into the second side of the blade, has an entry track extending from the hinge edge of the blade and an intermediate track extending from the entry track to and past the mounting hole.

    摘要： The present invention is directed to a device and method for removing build-up on such measurement gauges. The inventive device and method involve a movable scraper that fits around a cylindrical shield of a measurement gauge and continuously removes the build-up on the shield. Movement of the scraper is accomplished by a magnetic coupling between a magnetic core attached to the scraper, which is inside a pipe or other piece of equipment, and solenoids that are installed on the outside of the pipe. The device and method of the invention ensure instantaneously correct readings from the measurement gauge and improve control and operation strategies of heat exchanges, with significant economic advantages.

    摘要： An improved scraper is provided for removing paint, rust, scale and the like from the outer surface of elongated workpieces. The scraper comprises a pair of planar blade elements disposed in spaced relation in parallel planes transverse to the longitudinal axis of the workpiece and secured together by means of a scraper. Each blade has an edge shaped to engage substantially one-half of the periphery of the workpiece, with the edges engaging opposite sides of the workpiece for simultaneously scraping its entire surface. A handle is fastened to the spacer for applying leverage to the blade elements and for reciprocating the blade elements longitudinally of the workpiece thereby to effect the desired scraping action.
