Title: Improvements in fertilisers
IPC: C05D9/00
Filed: 1933-10-06
Abstract: Fertilizers are obtained by subjecting porous materials in the form of small rigid pieces, said pieces being other than pieces of coke of 1/20 inch size to 1/4 inch size, or mixtures of small rigid pieces of porous materials other than coke and small pieces of coke, to treatment to remove air by means of steam or a gas capable of condensation and/or solution in a liquid containing one or more fertilizing substances and then causing the thus treated porous materials to take up the said liquid.  If necessary, the pieces of porous material may be reduced to 1/2 inch size to 1/4 inch size after the above treatment.  The pieces may be impregnated in the above manner with p  the same or different fertilizing substances. The fertilizing substances referred to are ammonium nitrate, sulphate or phosphate, sodium nitrate, potassium chloride, calcium nitrate, and urea.  Examples of suitable porous materials are pumice, sandstone, calcareous sinter, kieselguhr, tufta, volcanic tuff, or mixtures thereof with or without the addition of coke. Examples of gases which may be used to remove air are ammonia and carbon dioxide. The pieces of porous material may be preheated before the current of gas or vapour is introduced.  When ammonium nitrate is the fertilizing material and particularly when pieces of coke are admixed with the pieces of other porous material, ignition is avoided by introducing the ammonium nitrate in the form of an aqueous solution at a temperature of below 100 DEG  C.  The pieces of porous material containing fertilizers may be provided with protective coatings of substances of low solubility and which act as a mechanical protective such as fine dry clay or coke dust or dust of manurial value.

Patent GB-389698-A (GB)
Title: Improvements in or relating to vehicle couplings
IPC: B60D1/06
Filed: 1932-06-25
Abstract: 389,698. Automatic couplings for vehicles ; locking-bolts. CODER, J., St. Marcel, Marseilles, France. June 25, 1932, No. 18027. [Class 103 (v).] In an automatic ball-and-socket coupling for vehicles, particularly tractor and trailer vehicles, one section 9 of the socket is arranged to swivel about a fixed pivot 10 so that, in its open position, Fig. 1, it is adapted to receive the ball 3, by which it is tilted rearwardly until the ball is gripped between the fixed and movable parts 99, 9 of the socket, when an automatic locking device secured the pivoted section in its closed position, the stem 27 of the ball in operation being inclined at a relatively small angle to the horizontal, and the parts of the socket being substantially symmetrically disposed in relation to the axis of the stem 27. For directing the ball 3 into engagement with the section 9 there is provided a semicylindrical or equivalent guide surface 20, the discharge end of which is at a higher level than the base of the socket. During the closing movement of the section 9, which takes place against the action of a spring 12, a projection 13 on the section engages a lug 14 on a spring-controlled pivoted locking-catch 1411 and swings the latter about its axis 21, against the action of springs 17, which ultimately cause the lug 14 to snap into locking position behind the projection 13 and so secure the entire coupling. For uncoupling, the lug 14 is rotated in a disengaging direction by actuating a handle 15, which is displaced until the springs 17 pass beyond the centre of the axis 21 as shown in Fig. 5, so that the catch 14<11> is held in a permanently inoperative position. The ball 3 is then free to be withdrawn, such movement being assisted by the springs 12, which return the section 9 to a ready-for-coupling position, the projection 13 now engaging a second lug 14<1> on the catch 1411 and restoring it to an operative position. Preferably in a tractor-trailer combination the socket is integral with or fixed to a casing 18 mounted on the tractor frame, while a stop 91 is provided to limit the movement of the section 9. The handle 15 may be operated by the driver pressing on a foot pedal connected to the handle by a chain. In a modification the fixed part of the socket is replaced by a second pivoted part actuated by a cam surface on the locking-catch. Ball joints.-To compensate for wear the ball 3, Fig. 16, is fitted with a renewable and adjustable screw plug 28 having a hard contact surface 29 and maintained in any set position by a spring blade 30 and screw 31. Or, as shown in Fig. 17, the contact surface may be constituted by a large ball 29<1> separated from the screw plug by a small ball bearing 29<11>.
