In a cycle of operation at the commencement of which a fresh charge of ground coffee is held on the plate 88 and partially leached coffee is retained on screen 50a, sufficient hot water for e.g. a single cup of beverage is passed downwardly through the container 8 from conduit 66 to conduit 68, Fig. 2, emerging therefrom as coffee. The container is then rotated through the rinsing position shown in Fig. 4, during which water from conduit 68 washes exhausted coffee off screen 50a. With continuing rotation, coffee held on plate 88 falls on to screen 49a and cover member 40, becoming uppermost, fully opens so that as the container rotates up to the horizontal position, (see Fig. 6), a further charge of fresh ground coffee is delivered to the container. The cycle of operations is then repeated. Reversal of the water flow between conduits 66 and 68 is effected by a sleeve member 16, detailed in Fig. 12 (not shown). If the plate 88 is removed from the brewing container, the apparatus may be then operated with a completely new charge of ground coffee during each cycle of operation.

Sulphur dioxide.-In a method of treating ores, minerals, and the like, broadly applicable to oxidizing, sulphidizing, and other processes, by a heat treatment, or a combined heat and chemical treatment, the finely-divided material is introduced into a rapidly-moving gaseous current, heated and supplied with any required reagent, in which it undergoes rapid treatment while travelling in suspension therein, and the molten or solid products are separated from the gaseous current and any volatilized products by collecting elements or baffles, the molten or solid materials falling from the elements or baffles into a collecting chamber. Fig. 1 shows a convenient form of apparatus. A chamber 9 having a lining 10 of fire-clay and a metallic covering 11 is provided with an air-pipe 13 and treating-agent pipe 14 at one end and opens at the other end into a collecting-chamber 8. It is surrounded by a waterjacket 15, with inlet and outlet pipes 16 and 18 in an outer metal casing 3. Air, admitted under pressure through the air-pipe 13, is heated in a zone X, X by a series of electric arcs 20, produced between inner and outer circular electrodes 21 and 22, controlled by switches 23. Further regulation of the temperature is effected by a water-spray 23a controlled by a needle-valve 24. Finely-divided material, preferably mixed with water, is fed through a pipe 25 and carried in suspension by the air current through the treating-zone Z. Z, which may be further heated by an electric are 26 and supplied with any required reagent through the treating-agent pipe 14. The products after treatment pass into a chamber 8 in which perforated baffles 28 only permit gases to pass through to a discharge-pipe 32, while molten particles, which may consist of slag-forming materials., mattes, and metals, flow down the baffles round the collars 30 surrounding the apertures 29 into the bottom of the chamber where they may be allowed to settle and be drawn off through pipes 30<1> according to their specific gravities, or solid particles stopped by the baffles fall by gravity and may be removed through a pipe 31<a>.

Abstract: 1461498 Clutch control JAWA NARODNI PODNIK 10 April 1974 [16 April 1973] 15942/74 Heading F2L A friction clutch 10, 11, 12 is disengaged through a fluid column 7 by pivoting of a control lever 2, and engaged by movement of an additional means (button 15 in the embodiment shown) in the same direction as that in which the lever 2 is pivoted to cause disengagement. The lever 2 moves a piston 5 in a cylinder 6 to disengage the clutch, and the button 15 is operated to open a valve 14 to thereby engage the clutch as fluid fills a chamber 17, moving a piston 18. Release of lever 2 allows spring 20 to pivot it back, and so piston 5 to suck fluid from chamber 17 into chamber 16 and return piston 18 to the illustrated position. In a second embodiment (Fig. 4, not shown) the control button 15 has an extension so that it can be operated by lever 2 on further movement in the disengaging direction. A further embodiment has a check valve between chamber 6 and the clutch so that the clutch remains disengaged after pivoting of lever 2 until a button is depressed to open the valve. The clutch control may be employed in a motor cycle used in dirt-track racing.
