Patent ES-272382-A1 (ES)
Title: Method of and apparatus for separating particles of different specific gravity in a jig
IPC: B03B5/24
Filed: 1961-11-25
Abstract: A mixture of loose solid material e.g. raw coal is separated on a perforated support i.e. screens 4, 41 in a wet jig 1 into fractions with different specific gravities according to a method in which liquid pulsations are caused by alternately increasing and decreasing the pressure of air in one or more chambers 16 located beneath the perforated support, the upward pulse of liquid in each cycle being brought about by so rapidly increasing the air pressure in the chamber or chambers 16 that the rate of upward acceleration of the liquid reaches 3 m./sec.2 in less than 100 milliseconds from the commencement of such pulse. The chamber or chambers 16 are fed with air from a supply line 17 by way of one or more admission control valves 18 in the form of flat discs which, or each of which is connected to the piston 30, Fig. 6, of a piston and cylinder unit operating to move the valve towards and away from a resilient seating 32, the movements of the valve being controlled by a cam or cams 24, Fig. 3, through the agency of valves 28, controlling the flow of a pressure fluid to the piston and cylinder unit or units. Raw coal is fed in along a shoot 6 on to the screen 4, the jig being divided into two compartments by a bridge 5. Owing to the liquid pulsations the raw coal is separated into a lower layer of shale and an upper layer of coal and middlings. The shale passes under a gate 8 operated by a float 7 and the coal and middlings pass over the bridge 5 on to the screen 41 where they are separated into a lower layer of middlings, leaving under a gate 12 operated by a float 11, and an upper layer of clean coal which is carried off in a shoot 15. The shale and middlings pass down conduits 9, 13 and are removed by a bucket elevator 10. The upward liquid pulsations raises the material fed from the screens 4, 41 substantially en masse, the compressed air admitted by the valves 18 pushing the liquid level down in the chambers 16. Before the air reaches the lower edges of the chambers 16 the valves 18 are closed and similar valves 20 connected with exhaust pipes 21 are opened to allow the liquid level in the chambers 16 to revert to its original level before the next cycle begins. The cams 24 are mounted on a shaft 23 driven by a motor 22 whose speed is regulable. The cams actuate switches 26 causing excitation of a coil 27 in an associated electrical cricuit. Each coil 27 controls a valve 28 thus causing opening or closing of the associated valve 18 or 20. The cams 24 are adjustably screwed to the shaft 23 and each comprises two adjacent concentric discs provided with high portions. By relative angular displacement of the discs the timing of the operation of the air admission and exhaust valves. Specification 1,009,424 is referred to.

Patent ES-302004-A1 (ES)
Title: A method of and an installation for treating cement raw slurry
IPC: C04B7/40
Filed: 1964-07-13
Abstract: Cement raw slurry is converted into raw meal suitable for burning in rotary kiln by mechanically reducing the water content of the slurry to form a cake, e.g. by means of a filter press, continuously feeding this cake to, and disintegrating it in, a stream of hot gas from the kiln to form particles, the majority of which are carried away in the gas stream, and subsequently separating the heated, dried particles from the gas stream and feeding them to the kiln. The particles not entrained by the gas may be either returned to the disintegrator or passed directly to the kiln. The disintegrator may be in the form of rotating rods or hammers. Figures (not shown) illustrate several flow schemes and disintegrators.
Patent ES-303484-A1 (ES)
Title: Pressure rollers for glass ribbon polishing machine
IPC: B24B7/24
Filed: 1964-08-26
Abstract: A method of imparting a substantially uniform surface to flat glass comprises advancing the glass in a predetermined path, subjecting one face of the glass to a surfacing operation and applying a pressure to the opposite face of the glass, which pressure can be varied at any section of a line transverse to the direction of advance of the glass so that it is more or less than the pressure applied at another section of the line to obtain a substantially uniform surface across the glass. As described, the glass 1 is advanced by drive rollers (not shown) over polishing blocks 2 consisting of felt pads, the blocks being arranged in two groups of three, each group being mounted on a rotatable spider. The glass, which is shown as thicker at its edges than at its centre, is pressed against the polishing blocks by a plurality of transverse lines of rollers 3. The ends of each roller are mounted in brackets 8 connected by struts 9 to hollow ribs 7 secured to the side members 5, 6 of a frame 4. Each strut 9 is vertically adjustable in its rib to vary the pressure of its roller relative to the pressure of other rollers in its line so that a substantially uniform surfacing action is effected across the width of the glass. The frame 4 is suspended by rods 10 from axles 13 having nose 14 for rotating the axles to lift the frame and rollers from the surface of the glass. The weight of the frame is counterbalanced by weights 17 and the lower position of the frame is determined by flanges 15 engaging stops 16. The frame is constrained to move in a vertical direction by guide members 21 associated with the corners 22 of the frame. The corresponding rollers in different lines may be of different lengths so that no part of the glass is unsupported during its entire travel past the surfacing blocks.

Title: Spring suspension device
IPC: F16F9/06
Filed: 1965-11-03
Abstract: A valve which permits throttled flow in one direction and relatively free flow in the opposite direction, is fitted in an hydraulic damper for a vehicle suspension. The road wheel (1), Fig. 1 (not shown) is linked to a piston (8) in a cylinder (9) which communicates through the valve (10) with a second cylinder (11) containing a free piston (12) loaded by gas pressure in a chamber (14B). The valve member 24 is spring centred in a position where a narrow cylindrical part 24 seals an opening 23. A slightly coned part 25 on one side permits throttled flow as the member moves upward and a flat face 24 on the other side allows free flow in the opposite direction. In extreme positions the movement is damped by end plugs 28, 30 which engage holes in a housing cover and in the valve member.
