Abstract: ABSTRACT        The apparatus for removing dust particles from an air stream, particularly for ventilating mines, comprises a centrifugal separator (3), which rotates in a housing (1), a blower (4), and a device (6, 7) for spraying or atomizing water and for delivering it to the air stream entering the centrifugal separator (3). The centrifugal separator (3) comprises a plurality of blade wheel sections (8, 9) having blades (14) which are joined to walls (10) which flare like funnels.      The blades of said blade wheel sections (8, 9) extend approximately in axial planes. Said blade wheel sections (8, 9) are preceded at the air inlet end by at least blade one wheel section (15) in which those generatrices of the blade surfaces (blades 17) which are equidistant from the axis are inclined by an angle of incidence (?) from lines which extend parallel to the axis in the axial planes (21), in a sense which is opposite to the sense in which the resultant (R) of the axial air entry velocity (v) and the peripheral velocity (u) of the blades (17) is inclined from the axial plane (21)  (Figure 2).

Abstract: ABSTRACT      An improved method and apparatus are disclosed for generating circular arcs of any arc length greater than zero up to and including a full circle of 360 degrees.          The method and apparatus can locate nonsymmetrical closest points for noninteger radius and arc center values.  The method and apparatus is capable of generating the incremental move commands for drawing an arc either in the clockwise or counter clockwise direction which is a distinct advantage when used to drive a pen type electromechanical plotter.  By dividing the generation of a 360 degree arc into eight octants, only two of the original eight directions need to be considered as candidate directions toward the next integer display matrix value to be displayed.  The method and apparatus employ a novel initialization which provides a simple stopping test for any circular arc of arbitrary length and direction.  Only simple addition and sign testing is used to display the circular arc.

Abstract: Abstract An air flow seeder is disclosed which has an arrangement for facilitating introduction of particulate materials such as seed and fertiliser into an air stream for distribution to seeding outlets.  The arrangement includes according to this invention, a conduit arranged to carry an air flow therealong, an opening through a wall of the conduit arranged to allow the particulate material to pass therethrough into the air stream, and within the conduit adjacent to the said opening an acrofoil member having a surface shape adjacent to the opening adapted to effect substantial lowering of pressure of air passing between the shape and the opening, and a surface shape on the other side adapted to facilitate air flow therepast.  Preferably, the further surface shape of the acrofoil member is substantially plannar and parallel to the facing wall of the conduit.  The first surface may be of stream-lined shape in cross-section to provide, with the wall of the conduit, a stream-lined constriction to effect a reduction in air pressure in its vicinity.

Abstract: BATHING ASSEMBLY                 ABSTRACT OF THE DISCLOSURE           A collapsible bathing assembly utilizes a flexible liner housed within a cabinet.  Rigid side walls for supporting the side walls of the liner axe pivotally joined to the cabinet, and by pivoting action move the liner into and out of the cabinet.  The rigid side walls and a rigid bottom support plate serve as the side walls and front wall of the cabinet when the liner is positioned within the cabinet and the bathing assembly is not in use.  A rigid end wall is mounted for pivotal movement about an axis adjacent to the bottom of the liner to provide for the adjustable supporting of one of the ends of the liner, particularly to provide for collapsing of that liner end onto the bottom of the liner, resulting in easy access to the bathtub for an invalid.  A framework is provided to support the top of the cabinet and to facilitate installation of the bathing assembly, including plumbing. The liner may be omitted, if desired, in which case the walls are provided with water-tight seals.

Abstract: ABSTRACT A method of gluing a transparent film onta a support having a window in it, is characterised by the fact that the film is coated over the whole of the surface of one of its sides with a thin layer of glue containing heat sea1ing products and a hardener.  The film is applied then pressed on the outer face of the support.     The product of this method is characterised by the fact that the film has glue distributed over the whole of its surface which makesit possible for it to be applied onto the support with a window in it, to adhere to the solid surface of the said support, and to form a perfectly transparent window in the support.     The heat sealing products ensure the adherence of the film on the solid part of the support, and the hardener ensures the polymerisation of the layer of glue at the leuel of the windows.

Abstract: Abstract of the Disclosure A method for correcting imperfections in an electro-optical light scanning system using a modulated laser illumination source directed upon a multifaceted rotating polygonal mirror or polygon.  The mirrored facets reflect the impinging light toward a moving photoreceptor and forms a raster of scan lines as the photoreceptor moves.  The method uses sensing optics and closed loop electronics for correcting inaccuracies in the position of the reflected light resulting from defects in the angular relationship between the plane of the facets and that of the rotating axis of the polygon as well as those errors due to inherent angular misalignment between each of the facets of the rotating polygon.
