    摘要： A pneumatic rapper has the upper end of a guide tube arranged to face an anvil operatively mounted on an object to be rapped. A ball hammer is disposed within the guide tube and is arranged to be propelled against the anvil. A concentric outer tube surrounds the guide tube for a portion of its length to define an annular accumulator chamber therebetween. A diaphragm valve is operatively mounted on the lower end of the outer tube and is arranged to have a central portion of its upper face close the open lower end of the guide tube to prevent pressure in the accumulator chamber from entering the guide tube. A control chamber exposes the diaphragm to a differential pressure to force the diaphragm to close the open lower end of the guide tube. Pressure in the control chamber may be selectively exhausted to flex and displace the diaphragm, such operation being effective to rapidly admit pressure from the accumulator chamber to the guide tube to propel the ball hammer against the anvil and to impart an impact to the object. A recoil spring functions to absorb the reactive energy on the diaphragm as the ball hammer is propulsively accelerated toward the anvil.

    摘要： A PNEUMATIC SINGLE-IMPULSE RAPPER FOR ELECTROSTATIC PRECIPITATORS COMPRISING A PISTON MADE FROM DRY-LUBRICATING MATERIAL WITHIN A UNITARY, FLANGE LESS, CYLINDRICAL HOUSING HAVING NO BOLTED CONNECTIONS, WITH THE PISTON BEING RETURNED TO ITS PRE-PULSE POSITION BY A SPRING HAVING REDUCED DIAMETER END COILS, SAID PISTON INCLUDING A SPHERICAL OR ALTERNATE STRIKING SURFACE FOR LOCALIZED IMPACT AGAINST THE END OF THE HOUSING, SAID HOUSING INCLUDING A NON-REMOVABLE CAP AND AN AIR INLET ADAPTED TO SECURE A STRENGTHENED AIR FITTING TO THE HOUSING. A BRAIDED WIRE PROVIDES ELECTRICAL GROUNDING OF THE RAPPER.

    摘要： A pneumatically operated rapper including a piston reciprocable within a cylinder adapted to strike an anvil within said cylinder thereby imparting vibrations to a structure connected to said rapper, wherein the improvement comprises providing said piston and said cylinder of dissimilar materials of which one material possesses dry lubricating properties and one of said dissimilar materials is covered with a thin film of low friction material which is erodable by abrasion between said piston and said cylinder to form microscopic particles for coaction with said dry-lubricating material, thereby conditioning the coacting surfaces of the piston and cylinder for reduced friction and continuous dry-lubrication thereof.

    摘要： The means and method for the cleaning and self-cleaning of an electrostatic precipitator is especially suited for adaptation to an electronic air cleaner comprised of an ionizer unit and a collecting cell unit adapted to be included in tandem within a suitable cabinet; means to bring air to be cleaned through these units are also provided, and these may or may not be an integral part of the cleaner. The ionizer unit may include support members for a plurality of ground plates between which are located ionizing wires which normally carry a low current but high voltage, preferably in the neighborhood of 10,000 to 14,000 volts. (Some electronic air cleaners, however, use voltages in the 5,000 to 9,000 volts range. This invention will also work effectively with them.) The collecting cell unit includes support members for a plurality of grounded collecting plates and there are a plurality of charged collecting plates suitably supported within the collecting cell unit and interleaved among the grounded collecting plates, the grounded plates and charged plates being out of electrical contact with one another. The charged plates normally carry a low current, high voltage charge in the neighborhood of 5,000 to 7,000 volts. The means and method of this invention, however, will function satisfactorily with all known voltage ranges normally applied to the ionizer and collecting cell in a 2-stage precipitator. Hopper means are located beneath the ionizer and collecting cell in position to receive precipitated contaminants which are removed from the air stream passing therethrough and which are intially collected on the various plates.
