Abstract: 1446065 Safety hitch LA MECANO-SOUDURE-REMOISE 10 Oct 1973 [11 Oct 1972 11 May 1973] 47404/73 Heading A1P Apparatus for hitching a tractor to an implement comprises a hook operated by the tractor lift mechanism, a spring biassed locking device for holding the hook in its upper position once engaged with the implement, a first safety device to prevent unlocking of the hook should the spring bias fail, and a second safety device to allow immediate uncoupling should the implement overturn. In one form, the hook comprises an implement engaging claw 6c and a projection 6d which, upon raising of the hook pivots cam shaft 17 against the bias of its end springs 24 until the cam 16 pivots into groove 6e. In this position the upper surfaces of transverse arms 13 are urged against cylinders of resilient material 45 which are housed in a plate 5 attached to the tractor and which constitute the first safety device. Should the springs 24 break the downward force exerted on the arms 13 by the resilient cylinders 45 maintains engagement of groove 6e and cam 16 and a projection 5b with pin 19. Should the implement overturn its coupling ring (not shown) engages arm 31 which pivots about shaft 34 to allow uncoupling. To uncouple, the hook is raised slightly by the tractor lift mechanism and the cam shaft is pivoted by actuation of a Bowden cable attached to a pin 18 Fig. 3. This then allows the hook to be lowered.

Abstract: 1,105,569. Air rectification process. BRITISH OXYGEN CO. Ltd. 9 Nov., 1966 [12 Nov., 1965], No. 48262/65. Heading F4P. In an air rectification process, a stream of saturated vapour, e.g. air, is withdrawn from a conventional column 4, 5 through a line 18 and is liquefied in an exchanger 15 cooled by a closed cyde refrigerant stream which remains gaseous and comprises one of the process streams, e.g., nitrogen, withdrawn from column 5 through a line 16. The refrigerant nitrogen is compressed at 10, extended in series arranged turbines 13, 14 and after cooling heat exchanger 15 is returned to compressor 10. The so-liquefied air is returned through a line 19 to column 4 to provide cold therefor. Instead of withdrawing wet air from the rectification column, wet nitrogen may be withdrawn through' a line 22 or wet oxygen through a line 23 and the liquefied product is withdrawn from the system through a line 24. Product liquid oxygen and nitrogen are withdrawn from the column through lines 20, 21.

Title: Clock apparatus and data processing system
IPC: G06F1/04
Filed: 1973-10-17
Abstract: 1452294 Adders AMDAHL CORP 17 Oct 1973 [30 Oct 1972] 48423/73 Heading G4A In data processing systems there is a delay in the passage of data from each latch to the next latch operating in the succeeding clock cycle and a delay CS (clock skew) between the same clockpulse arriving at different points in the system. According to the invention the relation between these delays and the clockpulse is such that the clockpulse width extends beyond that necessary to operate the slowest latch of the system to include a significant part of CS, the sum of the slowest latch time and CS is less than the minimum of the data path delays of the system and the cycle time of the clock is equal to or greater than the maximum data path delay. Preferably the clockpulse width is sufficient to include the whole of the clock skew plus a small margin. This choice avoids the necessity of building out the path delays to prevent race conditions and thus allows faster operation. The invention is described as applied to a multi-byte adder Fig. 2 (not shown) where the delay occurs in the adding stages connected between input and output registers operating in successive clock cylces. Clockpulses of the desired duration are produced by detecting in an AND gate coincidence between a reference clockpulse and the same pulse delayed in a chain of gates Fig. 6 (not shown).

Filed: 1967-10-30
Abstract: 1,206,775. Neptunium recovery. GENERAL ELECTRIC CO. 30 Oct., 1967 [17 Nov., 1966], No. 49266/67. Heading G6R. Neptunium (Np) is recovered from an aqueous solution containing Np and plutonium (Pu) by reducing the Pu to the Pu (III) state at an acid concentration of 2M or less, oxidizing the Pu to the Pu (IV) state and Np to a valency greater than IV by increasing the acid concentration to at least 4M, contacting the solution with an anion exchange resin to remove Pu, and recovering Np from the purified solution. The original aqueous solution containing uranium, Pu, and Np may be obtained by extraction with a dilute acid of an organic solvent extract of an acid solution of used UO 2 nuclear fuel. Reduction of the Pu in the solution to Pu (III), and of Np to Np (IV), is effected with hydroxylamine nitrate, aminoguanidine, ferrous ion, semicarbazide, or ascorbic acid. The solution is then mixed with boiling 7M nitric acid which destroys the reducing agent and oxidizes Pu to Pu (IV) and Np to a valency greater than IV. Pu is adsorbed on an anion exchange resin and the effluent solution again contacted with a reducing agent (e.g. a mixture of ferrous ion and hydrazine) to reduce the Np to the Np (IV) state. The Np is separated from uranium by adsorption on a second anion exchange resin bed, the effluent solution being evaporated to dryness and treated with fluorine to form UF 6 , free from residual fission products. The ion exchange separation steps may be carried out in semi-continuous movable bed equipment. Elution of Pu and Np from the resin beds is effected with dilute nitric acid, followed by concentration of the eluates. Specification 1,206,776 is referred to.

Title: Preparations containing dyestuff pigment or optical brightener
IPC: C09B67/00
Filed: 1976-11-26
Abstract: The colorants or optical brighteners are subjected in aqueous medium to a wet comminution until the particle size of the dispersion is less than 5 microns. After this, the dispersion is thoroughly mixed with a polar, organic solvent which has a limited solubility in the aqueous phase and together with this forms a settled two-phase system in which either, before the mixing, a water-insoluble, natural or synthetic, thermoplastic, organic compound is added as carrier substance to the organic solvent, or the addition of the carrier substance takes place after the mixing. The organic phase containing the carrier substance and colorant or optical brightener is then removed by successive addition of water, and the preparation particles are separated off and freed from the solvent-containing, aqueous phase by washing and drying. The preparations are obtained in pourable, non-dusting, granulated form and can be used for dyeing high-molecular weight organic materials.
