Abstract: A method and a device for insulating the spray liquid source from the high tension voltage of an electrostatic spray gun (13) when using an electrically conductive spray liquid. The spray liquid supply line (12) comprises an insulating device (14) in the form of a closed vessel (16; 26; 36) containing an electrically non-conductive liquid which is not mixable with the spray liquid and which has a density different from that of the latter. A sprinkler nozzle (21; 31; 41) is arranged to disintegrate the spray liquid into drops which are transported through the insulating liquid (17; 27; 35) by the influence of the difference in gravity acting on the two liquids. The spray liquid drops form a discontinuation of the electrical lead through which the high tension voltage propagates upstreams through the supply line (12). Thereby, the upstream parts of the supply line (12) including the spray liquid feed pump (11) and the spray liquid receptacle (10) are not reached by the high tension voltage. 
     A pump (30; 40) and passages (27, 28; 37, 38) are arranged to forcibly circulate the insulating liquid (17; 27) within the vessel (16; 26; 36) such that a movement is superimposed upon the spray liquid transportation movement such that the spray liquid flow capacity through the insulating device is thereby increased.

Abstract: A loudspeaker system which comprises a loudspeaker unit for radiating a first sound, a horn unit having a throat coupled to the back of the loudspeaker for radiating a second sound, and an acoustic filter provided in the horn for causing an acoustic impedance of the horn unit to be discontinuous. When the minimum frequency of cyclic dales of the sound pressure observed in the characteristic curves of a sound pressure of a composite of the first and second sounds as a result of a phase delay brought about by the length of the horn unit is expressed by fd, a primary harmonic resonance can be produced between the loudspeaker unit and the acoustic filter which is similar to that produced by a straight acoustic tube having its opposite ends closed, thereby to render the frequency of the primary resonance to be generally equal to the frequency fd.

Abstract: Polygon vertex data is processed in three steps to create a graphics display without hidden lines and without gaps in the displayed lines. The technique permits the processing of triangles rather than polygons having four or more sides. In the first step, the Z values for the display points for the visible edges of the polygons are identified and assigned a reserved value ZCLOSE in a frame buffer. In the second step, the polygons are tessellated into triangles and the Z values for the display points on the triangles are computed and each depth buffer storage location is updated so as to contain the value of points closest to the viewpoint while the frame buffer is written with a background colour. In the final step, the Z values for the display points of the polygon edges are again computed and compared with the corresponding Z values in the depth buffer. The depth buffer is updated with the computed values if the stored value is equal to ZCLOSE or if the computed value represents a position closer to the viewpoint than the stored value and the frame buffer is then written with a foreground colour for the display point in question.

Abstract: The present invention provides a technique for data detection signal processing for removing echo interference and/or distortion from a received 2B1Q coded signal. According to the preferred technique, the received 2B1Q signal Q, where q=(-3, -1, +1, +3), is shifted one bit to the left to generate a corresponding shifted symbol alphabet S, where S=(-2, 0, +2, +4). The shifted received signals are then processed through a transversal filter. That is, the signal is provided to a delay line which is tapped at intervals corresponding to the symbol width of the received signal. Each tap along the delay line is connected through an amplifier to a summing device that provides an output y(n), where
       
 The tap gains, or coefficients a j , are set to subtract the effects of interference from symbols that are adjacent in time to the desired symbol. 
     In an adaptive embodiment of the invention, the output y(n) resulting from the convolution between the transmitted symbols s(n) and the gain coefficients a j . The output of the transmission channel and the filter output y(n) are then processed in accordance with a convergence algorithm to develop an error feedback signal which is used to update the gain coefficients a j .

Abstract: This is an improvement for a powered floor scrubber (10) which in use is moved forward and backward across a floor to be scrubbed. A scrub brush (22) is rotated within a housing (20) which is open at the bottom and water is supplied within the housing. The improvement consists of attaching double lipped suction squeegees (34, 36, 42, 44) at both the front and rear of the housing and connecting them both to a source (48) of vacuum to suck up soiled water from the floor. The flexible squeegee lips are mounted in such a way that as the machine is moved forward the lips of the front squeegee fold together and shut off the airflow to it while the rear squeegee remains functional. When the machine is moved backward a reverse action of the squeegees occurs, so that there is always a functional squeegee sucking up soiled water behind the scrub brush while airflow to the opposite squeegee is shut off whether the machine is moving forward or backward.
