A briquetting press comprises at least one plunger to compress the material and extrude it through a discharge opening in the housing in which the plunger is accommodated and two rotary discs located on opposite sides of the plunger with their axes transverse to the plunger axis and preferably nearer a feed opening than the plunger, the disc surfaces facing each other being provided with friction surfaces which during rotation of the discs transport the material to the space adjacent the inlet end of the discharge opening. As shown the plunger 3 reciprocates in the discharge opening 5 defined by a replaceable nozzle 6. The rotatable discs (one of which 8 is shown) are mounted on axle 7 common to both discs and the friction surfaces are formed by projections 9 on their faces. Material entering the supply opening 2 is trapped between the projection 9 on the two discs and deposits on the shelf 11, creating a pre-compressed pile of material around the inlet to the discharge opening 5, so that on the forward stroke of the plunger the material is briquetted. The discs may be mounted on inclined axes so that their minimum separation occurs at the point farthest from the supply opening 2.

The compound (a) may be a hydride, double hydride, alkyl or alkyl fluoride, and (b) may be an organic compound soluble in hydrocarbons, e.g. a salt of a carboxylic acid of 4 to 24 carbon atoms; or of acetyl-acetone. Many examples of compounds (a) and (b) are listed. Some of these catalysts will also polymerize 1 : 2-diolefines, while not polymerizing 1 : 3-diolefines or monoolefines. Contact of the hydrocarbon with the catalyst may be at 0‹ to 200‹ under pressure high enough to keep the olefinic hydrocarbon liquid, and in the substantial absence of water and of any oxygen compounds other than those, if any, in the catalyst. Separations described in the examples are of hydrocarbons having 4 or 5 carbon atoms in the molecule. The monoenes and conjugated dienes obtained are useful for the preparation of synthetic rubbers and plastics.

A hairspring 32-34 is attached at its outer end to an anchor post 10 and the outer turn of the hairspring has an axial step 34 so that the portion 33 of the outer turn is disposed in a plane axially offset from and parallel to the plane of the remainder of the hairspring. The anchor post 10 is carried by an arm 9 having semi-circular fingers 8 which engage a step 7 on a bridge 4. A regulator is similarly mounted on the bridge by fingers 11. A disc 18 is attached to a pin 14 and is a close fit in a hole in the upper portion 19 of a jaw 20. A plate 16 has upturned edges (17, Fig. 2 not shown), and is slidable along the arm 9 until it just touches the outer turn of the hairspring, the edges (17) then being crimped against the arm 9. On rotation of the head 15 of the pin 14, the disc 18 is eccentrically rotated so that the jaw 20 is moved to clamp the end of the hairspring against the plate 16. A suitable tool is inserted in holes 27 and 28 in a plate 26 and the arm 12 of the regulator respectively so that a reduced portion 30 of a curb pin 29 is slightly spaced from the portion 33 of the hairspring. A screw 23 is then rotated to trap the hairspring between the reduced portion 30 and a boss 25 threaded on the screw 23. Further rotation of the screw 23 clamps the plate 26 and the arm 12 between the head of the screw and the boss 25. Angular adjustment of the anchor arm 9 and the regulator arm 12 may then be effected by rotating the arms about their respective axes 35, 3.

The outer tubular component is fixedly secured to a tubular casing 10 which is rotatably driven in the trolley through gears 16, 16<SP>1</SP> and square shaft 17 from a reduction gear motor (not shown) which also effects movement of the trolley along rail 4 through chain 7. The tubular screw may be rotationallyfixed to the trolley. Alternatively, as shown, the screw may be rotatably driven preferably in the opposite direction to the outer component by gears 27, 28, 29 so that relative inner/outer component displacement can be achieved with a practical screw pitch on the tubular screw. Blowing fluid is controllably fed to a feed tube, which is coaxial of and opens into the tubular screw, by a valve 13 actuated on trolley movement by a cam and lever arrangement, illustrated in a known soot blower of Figs. 1A, 1B (not shown), and a portion of the blowing fluid is bled through ports 32 in the tubular screw to the space between the tubular components to cool the same and to cool a bearing 21 between the outer end of the outer component and the inner component, said bearing being mounted of fins 38 to permit the passage of fluid therepast. In modified embodiments, Fig. 3A, 3B and Figs. 4A, 4B (not shown), the outer tubular component is formed by two concentric tubes 33, 33<SP>1</SP>, all or part of the blowing fluid passing to the annular space between said tubes.
