Each of a dust collecting electrode (40) and a high-voltage electrode (50) that constitute the dust collecting part (30) includes: a base (41, 51) with a rectangular grid structure having a large number of vent holes (46, 56) formed therein; and projections (42, 52) extending into the vent holes (56, 46) of the opposed electrode (50, 40). The dust collector collects dust by generating an electric field between the dust collecting electrode (40) and the high-voltage electrode (50).

Abstract: Disclosed is a filtration enhancement apparatus and an associated method. The apparatus includes a number of electromagnetic grids that are placed in series. The first grid conditions ambient particles to generate particles with both a positive and a negative charge. These charged particles are then delivered to a second and third grid wherein a low, medium, and/or high frequency alternating current is employed to force the positive and negative charged particles to collide and conglomerate with one another. The conglomerated particles are then sent into the ambient environment for subsequent filtration.

Abstract: Ionic emission electrostatic device (1) for depositing on the surface (sp) of a multitude of aerosol particles (p1, p2, . . . , pn) within a fluid (F), a quasi-homogeneous quantity of ions (iq). This electrostatic device (1) is constituted by a conductive discharge corona electrode (EC) and a noncorona conductive receptor electrode (ER). The pseudo-planar active face (SA) of its receptor electrode (ER) is covered by a plurality of craters with sharp edges, in a closed pseudo circle, exhibiting on their end edges (Ai) a section of minimum bend radius, and enclosing the orifices (O1, O2, . . . , On) and terminating towards the outside of the active face (SA). The craters are distributed quasi-uniformly on the active face (SA), in its two geometric directions. The surface flow of ions (iq) originating from the corona electrode (EC) and in the direction of the active face of the receptor electrode (ER) has an increased homogeneity.

Abstract: An electrostatic air cleaning device includes an array of electrodes. The electrodes include corona electrodes connected to a suitable source of high voltage so as to generate a corona discharge. Laterally displaced collecting electrodes include one or more bulges that have aerodynamic frontal “upwind” surfaces and airflow disrupting tailing edges downwind that create quite zones for the collection of particulates removed from the air. The bulges may be formed as rounded leading edges on the collecting electrodes and/or as ramped surfaces located, for example, along a midsection of the electrodes. Repelling electrodes positioned between pairs of the collecting electrodes may include similar bulges such as cylindrical or semi-cylindrical leading and/or trailing edges.

Abstract: A particle filter for microelectromechanical systems is provided that includes a particle trap formed on a substrate material. The particle trap includes an array of multidimensional geometric structures in an adjacent relationship. The geometric structures further define a plurality of multidimensional voids therebetween for trapping particles therein. The individual multidimensional geometric structures are formed by a plurality of vertically interconnected geometric shapes to define different configurations of voids between the adjacent geometric structures. In one embodiment of the filter system, an electrical bias is applied to the array of multidimensional geometric structures to facilitate attracting and trapping of particles in the filter.

Abstract: A multipurpose fitness machine including a substantially U-shaped supporting frame having a transverse frame section and two longitudinal frame sections respectively connected in parallel to two opposite ends of the transverse frame section at right angles, a bench pivoted to the longitudinal frame sections of the U-shaped supporting frame at one end and having two longitudinal racks at the bottom side, and an operating frame unit adapted for supporting the bench on the U-shaped supporting frame for turning by hand to lift the bench from the U-shaped supporting frame when the user sits, lies, or stands on the bench.

Abstract: A collector plate (10) for an electrostatic precipitator is provided. Collector plate (10) has end portions (12) which are substantially symmetrical about the plane of the collector plate (10). Each end portion (12) is preferably polygonal and has a substantially unobstructed interior. Dimples (80) may be located in end portions (12) to improve rigidity of the plate. Collector plate (10) yields better precipitation results because of the minimal or nonexistent deflection of plate (10) into voltage discharge regions surrounding electrodes (36) within the precipitator. Precipitation results are further improved because power input to the precipitator is not limited by an instable electric field resulting from irregularities in the surface of plate (10).

Abstract: A horse riding simulating exerciser includes a rod for securing a foot support and a seat post pivotally coupled to a middle portion of a frame at a pivot axle and coupled to the rod. A track is secured on the seat post for carrying a slide. A handle is pivotally coupled to the frame and a lever couples the handle to the slide. When the slide is moved to one side of the pivot axle, the seat cushion may be elevated by pulling the handle. When the slide is moved to the other side of the pivot axle, the seat cushion may be elevated by pushing the handle upward.
