A machine such as a crank and punch press or embossing machine comprises a member 3, e.g., a piston or crosshead, mounted for reciprocation by a crank-shaft 1 and connecting-rod 2, and two counterweights 7 connected to the member 3 by a pivoted rod 5 and a pivoted lever 6 so as to move in the opposite sense to the member 3, the counterweights being restrained at their ends remote from the member 3 by means which prevent uncontrolled swinging thereof. These means may comprise pivoted levers 10 and pivoted rods 9 and 11, whereby the counterweights are also caused to have a transverse component of movement to balance the forces arising from the rotation of the crank-shaft. In simpler embodiments the counterweights are simply pivoted together at their remote ends (Fig. 2, not shown) or each pivoted to a fixed point by a rod (8, Fig. 1, not shown).

As shown, the member 41 is driven by a sleeve 34 through splines 42 and is normally coupled by facial teeth to the member 52 which drives a track laying assembly 29 through gearing 11 and sprocket 27. When it becomes necessary to tow the vehicle, the members 41, 52 can be uncoupled by removing a cover 76 and unscrewing the lock nut 79 to increase the length of a tie rod 67, thus allowing the member to move axially by the action of springs 74.

A stop 38 may be slid radially to block part of the guide slot 36 to give the full line position of the tines shown in Fig. 3 for tedding hay; when the stop 38 is retracted, the tines adopt the chain-dotted position of Fig. 3 for windrowing using the swath boards 9. The stop 38 is located by a spring- loaded ball 43 engaging in one of holes 44. Alternatively, the stop 38 may be replaced by a slotted arcuate plate superimposed on the slot 46, which plate may be inverted to alter the effective length or position of the slot 36 and hence the operative positions of the tines. Pads 30A of plastics permit relative rotation of element 27 and annulus 14 but with some resistance. The implement is supported by ground wheels (not shown) beneath the rake members 1. The swath boards 9 may be swung upwards into inoperative postions for tedding or transport. Operational angles between the parts are specified.

Abstract: 1,202,559. Sulphur. UNIVERSAL OIL PRODUCTS CO. 18 Dec., 1967 [27 Dec., 1966], No. 57322/67. Heading C1A. Sulphur is produced from sulphide solutions, e.g. wastes from treating petroleum, by oxidizing said solution in a first zone with free oxygen containing gas in an amount of 0.50 to 0.9 atoms of oxygen per atom of sulphur in said solution, in the presence of a solid oxidizing catalyst, thereby effecting a substantial conversion of said sulphide to a soluble polysulphide, separating the liquid from the solid catalyst and passing this liquid to a second zone where at least some of the polysulphide is decomposed and the resulting elemental sulphur and sulphide compounds recovered. The catalyst material may be a metal phthalocyanin, e.g. of Fe, Ni, Cu, Mo, Mn, or W supported by a carrier material, e.g. activated carbon, or alternatively the catalyst may be a metal sulphide, e.g. of Ni, Fe, Co or mixtures thereof supported on a carrier. The reaction conditions for effecting the polysulphide formation are preferably a temperature in the range 0 to 200 C. and a pressure which maintains the sulphide solution substantially in the liquid phase. The decomposition of the polysulphide may be effected by treatment with acid and/or by heating the solution to a temperature 50- 150 C. higher than that temperature at which the first zone is maintained. The sulphide solution used may be an alkaline aqueous solution of a sulphide compound, e.g. an aqueous ammoniacal solution of H 2 S. When H 2 S is the residual sulphide of the second reaction zone it may be stripped from the effluent of this zone with an inert gas, and the stripped H 2 S absorbed in an aqueous ammoniacal solution which is then recycled to the first reaction zone.

The risk of capsizing is thus reduced. As illustrated, a spring 22, formed of rubber cords, acts via wires 18 and 19 on pulleys 21 at the bottom of port and starboard shrouds 10 and 11. When the mast is vertical, the ends of the spring lie against stops 24 in which circumstance it is prestressed so that the mast behaves as a rigidly supported mast when the wind force is below a value corresponding to the degree of prestressing. The mast may be buoyant, for example it may carry a float 25, whereby in the event of the vessel overturning, if the lowermost shroud (when the vessel is overturned) is shortened and the uppermost shroud lengthened, the resulting change in angle of the mast relatively to the hull results in the hull being moved into a position in which the vessel can right itself.
