摘要:
A surface cleaning suction type appliance comprises a housing, an airstream suction source, a cyclone main body, and a dirt cup. The housing includes a main suction opening. The airstream suction source is mounted to the housing and includes a suction airstream inlet and a suction airstream outlet. The suction source selectively establishes and maintains a flow of air from the main suction opening, via the airstream inlet, to the airstream outlet. The cyclone main body is supported by the housing and is in communication with the main suction opening. The cyclone main body has a uniform outer circumference and includes a first stage separator, and a plurality of downstream second stage separators. The lengths of the second stage cyclonic separators are different for any number of adjacent pairs of separators from on pair up to all adjacent pairs of separators. The dirt cup is connected to the cyclone main body. The dirt cup includes a first particle collector and a second particle collector. The first particle collector communicates with the first stage separator for collecting dust particles from the first stage separator. The separate second particle collector communicates with the plurality of second stage separators for collecting dust particles from the second stage separators.

A cleaning machine for cleaning a surface is provided. The cleaning machine includes a base assembly that moves along the surface and a liquid distribution system associated with the base assembly for distributing the cleaning solution to the cleaning surface. A suction nozzle assembly is mounted to the base assembly and includes a front nozzle portion and a rear nozzle portion. The front nozzle portion defines a fluid flow path having an inlet opening and an outlet opening and the rear nozzle portion defines a fluid flow path having an inlet opening and an outlet opening. A suction source is in fluid communication with the suction nozzle for applying suction to draw the cleaning solution and dirt from the surface and through the suction nozzle assembly. The fluid flow path of the front nozzle portion is closed in response to the base assembly moving in one of the forward direction and rear direction. The fluid flow path of the rear nozzle portion is closed in response to the base assembly moving in other one of the forward and rear direction.

The present disclosure provides a vacuum cleaner including a nozzle base having a main suction opening and a housing pivotally mounted on the nozzle base. An airstream suction source is mounted to one of the housing and the nozzle base for selectively establishing and maintaining a suction airstream flowing from the nozzle main suction opening to an exhaust outlet of the suction source. A filter housing is mounted to one of the nozzle base and the housing. The filter housing comprises a filter mounted in the filter housing. An ultraviolet light source is disposed in the filter housing and shines on the filter for disinfecting same.
摘要:
The present invention relates to systems of methods of detecting and measuring inclusions in liquid metals. More particularly, non-metallic inclusions having a conductivity level different from the liquid metal melt are forced to migrate and are collected on a measurement surface using electromagnetic Lorentz forces. The inclusions and their concentrations are detected at the measurement surface using either an electrostatic detection system or an optical detection system.

A soccer board game and a method for playing it by first and second contestants is disclosed. The game board included a board comprising a grid of distinctly marked squares with soccer field markings. The soccer field markings include a half line dividing the field into two half fields, a kick-off circle on the half line, two opposite goal boxes located on opposite ends of the field, a five-zone and a sixteen-zone areas adjacent each of the goal boxes. The board game includes at least one die; a ball; and opponent first and second teams of players, each team pertaining to one of the contestants.
