Abstract: An intermittently operated apparatus for cleaning dust laden gases has a gas-tight housing, a pair of spaced gas-permeable walls holding a filter bed consisting of granular filter material. A centrally located conveying pipe is mounted to the housing for regenerating the filter bed after a predetermined amount of operating time. A high electric potential is applied in the region of the filter bed for removing dust particles from the dust laden gas which is flowing through the permeable walls and the filter bed. From time to time, the gas cleaning mode is interrupted and the granular filter material of the filter bed is regenerated by fluidizing the same in the conveying pipe. A system comprising a plurality of such filtering apparatus always maintains one of the apparatus in a regenerating mode while the remaining filter devices are in gas cleaning mode. Thus, the simultaneous operation of cleaning and regenerating is accomplished. The use of a filter bed having a thickness of about 25 to 100 mm. and consisting of granular filter material having a grain size of about 0.5 to 2.0 mm. in combination with application of high electric potential charge of about 10,000 to 60,000 volts achieves significant improvement over prior apparatus and methods.

Abstract: A method and apparatus for minimizing backlash and improving the efficiency of speed reduction mechanisms in which a series of rollers are equally spaced in a circle on a disk to perform operationally somewhat like an internal ring gear. Mounted for eccentric movement and simultaneously engaging each of the rollers is an orbital rotor having a perimeter defined by an epitrichoid curve with a numer of lobes equal to one less than the number of rollers. The rotor is mounted for free rotation on an eccentric keyed to a drive shaft. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes on the rotor. A similar structure may serve as a second stage with a second orbital rotor driven by the first rotor and moved orbitally by the same eccentric. In carrying out the method of this invention, each of the rollers is individually adjusted to bring it into engagement with the rotor under controlled pressure and compliance. Each roller is mounted for controlled omnidirectional compliance and preloaded to provide an controlled pressure between each roller and the adjacent surface of the rotor. The outer surface of each roller is crowned to increase the efficiency and prevent binding that might be caused by angular deflection of the roller.Each roller is mounted on a shaft that is pressfitted into an eccentric bore in a mounting sleeve that is enlarged near the roller to provide for controlled deflection of the shaft as the sleeve is rotated in its mounting. Each roller is individually adjusted to produce a controlled preload pressure between the roller and the rotor.

Abstract: A flowmeter has a tank disposed between a discharge circuit and a supply circuit from which the tank is refilled when the level of the liquid in the tank falls below a predetermined level. A plunger is suspended in the tank by a force sensor. The output of the force sensor is used to measure the rate of flow from the tank to the discharge circuit except when the tank is being refilled. Flow from the tank during a refilling cycle is approximately measured in response to flow parameters in the discharge circuit which are independent of the force sensor and liquid level in the tank. The flow parameters in the discharge circuit are monitored and calibrated during each tank discharge cycle, and the new calibration values are used during the next tank refilling cycle, to obtain reasonably accurate continued flow measurement during each tank refilling cycle.
