Abstract: A linear actuator for e.g. a disk drive has a fixed member (19) and a movable member (101). One of those members (19,101) carries at least one track (3) of permanent magnets extending in the direction in which the movable member (3) is to move, with adjacent permanent magnets having alternate magnetic polarity. The other member (19,101) has first and second drive parts each having at least one pair of opposed sets of teeth (1,2). The or each track (3) passes between those teeth (1,2). Each pair of teeth (1,2) is associated with a corresponding drive coil (4,5) giving the teeth (1,2) a magnetic polarity so that there is a magnetic alignment between a polarity of the teeth (1,2) and the permanent magnets (3). The drive parts are arranged so that, for any given relative position of the first and second members (19,101), the magnetic alignment of the teeth (1,2) of one drive part is out of phase with the magnetic alignment of the teeth (1,2) of the other part. In order to ensure that the magnetic alignments are out of phase, there may be a physical displacement between the teeth (1,2) of the two drive parts. This displacement may be (m ± 1/2).T p  where m is an integer and T p  is the teeth pitch. This gives a phase displacement of 180°. Alternatively, the drive parts may be aligned, and two tracks (3) of permanent magnets be provided with the magnets thereof having opposite polarity for a given track position, or the drive current to the drive coils (4,5) may be controlled to be out of phase. Such arrangements permits smooth driving of the movable member (101).

Abstract: A hydrometallurgical method comprising a leaching operation is provided for recovering copper from particulate copper sulfide flotation concentrate containing at least about 20% copper by weight, a significant portion of the copper in the copper sulfide concentrate being in the cuprous state. The copper sulfide flotation concentrate in the finely divided state is subjected to leaching with an alkaline solution of ammonia plus ammonium sulfate of concentration ranging from about 30 gpl to 150 gpl of ammonia and about 25 gpl to 200 gpl of ammonium sulfate at a temperature ranging from about 10°C to 95°C, preferably about 20°C to 40°C, the amount of sulfide concentrate in the leaching solution ranging from about 25 gpl to 500 gpl proportioned at least stoichiometrically to the ammonia concentration of the leaching solution. The sulfide concentrate is leached under substantially ambient pressure while continuously aerating the solution for a time at least sufficient to dissolve the cuprous copper and oxidize it to the cupric state while avoid or substantially minimizing the oxidation of sulfide sulfur to sulfate, and thereby obtain a filtrate containing at least about 15% of the total amount of copper in the concentrate and provide a washed residue containing at least about 20% copper by weight comprised substantially of cupric sulfide. The copper in the leaching solution after further processing is subsequently recovered by electrowinning. The residue can be further treated in a smelter to recover copper therefrom or upgraded by subjecting the residue to conventional flotation and provide a secondary flotation concentrate containing at least about 30% by weight of copper.

Abstract: A method of treating coal. The method comprises passing the coal through a retort having a shell temperature of about 500-1000 ° and shock heating the coal to a maximum surface temperature of about 500-1000° without allowing the coal to become exothermic. The coal is prevented from going exothermic by a combination of factors, including the evaporation of moisture from the shock heated coal, the tendency of coal to absorb heat and maintain a temperature of about 390-570 ° F until the coal undergoes molecular transformation of comp lex hydrocarbons contained in the coal to simpler forms, and the effects of a cooling blanket gas passed through the shock heated coal. The blanket gas preferably comprises an oxygen lean blanket gas stream containing about 2-8% oxygen by volume. The treated coal exhibits extremely low moisture content and increased BTU value and other improved combustion characteristics.

Abstract: A data processing system converts a raster image of grey scale value pixels into an image of binary value pixels (38) and diffuses pixel value errors that result from the conversion. The data processing system initially converts a grey scale value pixel (38) to a binary value pixel (42), determines an error value for the pixel by finding a difference between the pixel's binary value and its grey scale value; derives (72) error diffusion values attributable to immediately adjacent pixels in a next line of the raster image and stores those attributable error diffusion values. Upon reaching one of the immediately adjacent grey scale value pixels in the next line, and during a conversion of that pixel from its grey scale value to a binary value, the attributable stored error diffusion values are accessed and combined (66) with the pixel's grey scale value and with the attributed error value that arises from the immediately preceding pixel in the same line.

In order to be able to separate off continuously a low-suspended-material part-fluid-stream from the contaminated fluid stream, according to the invention it is proposed that a vortex zone is created in the suspended-material-loaded fluid stream beneath its surface by a specific deflection and reversal of the flow, which vortex zone enables only heavy and inert suspended particles to maintain their flow path and includes a substantially flow-free and vortex-free space into which a part-fluid-stream, composed of the lighter molecules and thus purified, continuously penetrates, in order to be measured here or to be continuously withdrawn from this space. <IMAGE>

Abstract: A frequency stabilizer for use in a time-division multiplexed digital cellular system is designed to reduce the consumption of electric power by means of a receiving circuit in continuous frequency control. The frequency stabilizer includes a pair of latches 4 and 5 for latching a phase error of an output signal from a phase error integrating circuit 2, a subtractor 6 for outputting the difference between respective output signals from the latches 4, 5, and a selector switch 8 for selecting and outputting an output signal from a phase-to-frequency converter 3 in the period of a reception slot and an output signal from a frequency correcting circuit 7 between reception slots. When the selector switch 8 is selecting the output signal from the frequency correcting circuit 7, no electrical energy is supplied to the receiving circuit. Even when the frequency stabilizer is in continuous operation, the receiving circuit operates only during the reception slot, resulting in reduced consumption of electrical energy.

Abstract: An apparatus for positioning a magnetic tape head (3) transversely relative to a length of magnetic tape in a magnetic tape recorder along a shaft. The shaft (6) vertical axis may be slightly tilted to compensate for manufacturing tolerances and achieve the necessary alignment of the magnetic tape head to the magnetic tape (3) path. To accomplish this, one end of the shaft (6) is supported in a washer bracket (12) for connecting that end of the shaft to the tape drive frame (1). The washer bracket (12) is pre-loaded axially of the shaft (6), such that a directing force applied to that end of the shaft permits the washer bracket to slide in a direction transverse to the axial direction of the shaft on the frame. Otherwise, the washer bracket (12) frictionally abuts the frame (1) and holds that end of the shaft (6) in fixed position on the frame (1).
