Abstract: 1308066 Plough linkages KYLLINGSTAD PLOGFABRIK AS 1 July 1970 [1 July 1969] 31882/70 Heading A1P A universally-jointed plough linkage for joining plough member 2 to the draw-links 10 of a tractor comprises a biasing device i.e. rod 12 which engages links 10 and forwardly extending arms 11, secured to horizontal pivot 9 which forms part of the universal-joint. When the tractor makes an abrupt turn (such as shown in prior art Fig. 2) member 2 tends to turn about pivot 9 causing arm 20 (Figs. 3, 4) secured to pivot 5 to swing downwardly at its rear end, at the same time causing arms 11 to press rod 12 harder against links 10. The spring 15 on pin 13 which has a stop 14 is compressed by bottom 17 of length-adjustable cylinder 16, 18 and the turning movement of member 2 is resisted. The effect of spring 15 can be adjusted by turning screw .threaded part 16 in screw-threaded part 18.

Abstract: 618,171. Potato-planting machines. GODLEWSKI, J. Oct. 30, 1946, Nos. 32211/46 and 8334/47. [Class 6 (i)] A potato-planting machine comprises in combination a wheeled chassis A carrying a plurality of rotary dibblers 21 driven from the land wheels 13 through gearing such that the peripheral speed of the dibblers exceeds that of the land wheels, and a feed shoot associated with each dibbler for feeding potatoes from a hopper 28 to the holes made by the dibblers. A unit comprising a pair of blade members 59 and a roller 66 is trailed behind each dibbler to fill in and consolidate the soil. The hopper 28 contains inclined grids 30 over which the potatoes gravitate towards outlets 32 (Fig. 4), this action being assisted by a hand lever 36 which oscillates the bottom grid. The potatoes are passed singly into the feed shoots 44 by pocketed rotary valves 45. Each dibbler comprises a hollow drum 20 carrying a pair of tubular arms 21. The drum has two kidney-shaped openings 46 which register with the end of the feed shoot 44. The drums are mounted on a common axle 10 and driven thereby in one direction only through the action of spring-loaded plungers 26 which engage grooves in the axle 10. Each shoot 44 contains a pair of flap valves 51, 52 (Fig. 5) adapted to ensure the feeding of potatoes singly to the drums. The valves are operated in sequence by a follower 55 engaging a cam surface formed on the drum. The hopper 28 can be tilted relatively to the chassis by means of a lever 19 actuating an eccentric 42. A seat is provided for an operator at the rear of the machine. The first Provisional Specification describes a modification in which the dibblers are not hollow, the potatoes being fed to the ground by tubes.

The end rollers on each shaft have a portion 24 of reduced diameter running on rails 14 and 15 to produce rotary motion of shafts 19 and rollers 20. A small potato eliminating structure 10 used in conjunction with the above comprises a plurality of shafts 44 each carrying a plurality of rollers 45 similar to rollers 20 and journalled in bearing mounts 43 (only four shown) slidably mounted on rails 41, 42. The shafts are rotated in the same direction by belt means (Fig. 9, not shown) to move potatoes towards the cutting machine proper. Sets of bearing mounts 43 are connected by screw thread means having sections with differing thread pitch and/or direction such that rotation of handles H enables the spacing between members of a set to be varied to allow potatoes below the desired size to fall through, while the spacing between different shafts within the set is maintained equal.

Title: Process for the production of metal and metalloid oxides
IPC: C01F7/30
Filed: 1953-11-25
Abstract: <PICT:0748524/III/1> Metal or metalloid oxides are produced from their decomposable salts by continuously introducing a salt of the metal or metalloid suspended in the hot inert gas into a reaction zone externally heated to above the decomposition temperature of the salt, whereby the salt is decomposed in the absence of combustion products, separating the solid oxide from the gases at a temperature above the recombining temperature thereof and dividing the separated gases into two portions one of which is discharged whilst the other is heated and thereafter has fresh salt suspended therein and is re-introduced into the reaction zone.  The invention is particularly described in respect of the product of aluminium oxide from aluminium sulphate and is shown in the drawings where a reactor 10 is externally heated to above 770 DEG C. and aluminium sulphate is supplied thereto from pipe 14 entrained in a gas stream entering at 16.  The gases with entrained oxide pass successively through cyclones 18, 19 and 20 from which the product oxide is withdrawn from line 26, the gases thereafter passing through line 29 to a vale 34 from which a portion of the gas is bleed off through line 32.  The remainder of the gases passes through line 36 to a re-heater 38 where they may be heated to 700 DEG C. for example after which they pass through line 16 to entrain further sulphate.  Sulphur oxides are recovered by conventional means from the gases leaving at 32.

In a thermal switch of the differential-expansion rod-and-tube type, the rod 2 is screwed to a sleeve 4 passing through the insulating dustproof cover 13. Movement of the rod 2 is transmitted to a lever 7, pivoted on a knife 6, by a prism 8 whose upper face abuts the sleeve 4 and whose two knife edges engage a groove 7b on each side of the rod 2. A T-shaped rocking- lever 9 is urged by over-centre tension-springs 10 into a groove in the end 7c of the lever 7, so that normally the contacts 20, 21, are held closed by the resilience of blade 18, and an insulating-plate 12 on the rocking lever 9 abuts the contact 20. When the rod 2 is lowered on increase of temperature, lever 7 is rotated to raise the end 7c and move it over the line of centres, whereupon lever 9 snaps over and an insulating bar 22 secured to the plate 12 engages the blade 18 and moves it into the open position. The bar 22 may actuate up to three blades and the operating temperature is set by an adjustable knob 5. The switch operation may be reversed by interchanging the elements 1, 2, or by disposing the knife 6 on the other side of rod 2.

In a self-priming pump driven by an I.C. engine, a movable member in the outlet from the pump is responsive to liquid flow and is connected to control the fuel supply to the engine so as to cause it to idle in the absence of flow. A self-priming pump of, for example, centrifugal type. discharges through a pipe containing a pivoted semi-circular vane 8 which is connected by a Bowden cable 14 to the throttle lever 16 of the I.C. engine which drives the pump. The vane 8 is not affected by the. flow of air during priming, but when priming is completed the flow of liquid rocks the vane to open the engine throttle from the idling position..The engine is then controlled by a constant-speed governor. As shown, the vane 8 may be contained in a threaded adaptor 20 which can be fitted to an existing discharge pipe 6. Alternatively, it may be contained in a flange interposed between the pump body 28 and the pipe flange 30.
