Title: Dyeing nylon fibres
IPC: C09B45/16
Filed: 1964-12-03
Abstract: The invention comprises a composition comprising at least one non-metallised and non-metallisable acid dye that is capable of dyeing nylon fibres from a substantially neutral to weakly acid solution, and at least a molecular equivalent of a premetallised azo dye-chromium-complex containing at least one sulphonic group, wherein the dye and Cr are present in a molar ratio of 1:1, the premetallised dye is free of dye-metal complexes in which the dye metal ratio is 2:1, and the metallised portion is free from unchromed dye and is soluble in neutral and weakly alkaline aqueous solutions, and wherein the premetallised dye is one in which the Cr is bound to an azo dye by reaction with groups positioned ortho, ortho\sv to the azo linkage one of these original groups being -OH and the other being -OH1 -NH2 or -COOH.  Some 1:1 Cr complexes may have their water-solubility increased by further complexing with certain aliphatic carboxylic acids.  The dye compositions can be applied to nylon simultaneously from a single bath or the individual components of the composition can be applied sequentially from the same bath or sequentially from different dyebaths.  When the dyestuffs are applied sequentially from the same bath the dye composition is applied to nylon fibres from an aqueous solution, the fibres remaining in the solution until the acid dye component is completely exhausted and thereafter the fibres are dyed in the presence of acid at elevated temperatures with a sufficient quantity of the premetallised dye component.  When the dyes are applied from different baths, the non-metallised dye component is first applied and thereafter the premetallised dye is applied. The preferred method involves applying the dye compositions from a neutral dye bath to dye on the acid dye component and then lowering the pH to dye on the premetallised dye component. Examples of the dyeing processes are given.

Abstract: 1,167,502. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 9 Nov., 1966 [23 Nov., 1965], No. 49744/65. Heading G6C. A spacer grid for a fuel assembly comprising a plurality of fuel rods clustered in spaced array is of cellular form, the grid cells each having projections which are adapted to engage, and thereby locate, a fuel rod extending through the cell and which are shaped to possess inclination with respect to the axis of the rod and also with respect to the plane of the grid so as to promote mixing or swirling of coolant in a coolant flowstream passing through the cell. In the embodiment described, the cells are of hexagonal section and provided with inwardly directed projections on alternate walls. The projections are of elongated form and each slopes in extending from a lower to an upper region of its wall. In each cell the three projections are similarly orientated so that the coolant has a rotational component of flow imparted to it. The projections have rounded ends to limit the pressure drop experienced by the coolant. The coolant mixing effect may be enhanced by the promotion of turbulence by eddy diffusion in the coolant leaving the grid. To this end the downstream edges of the cells are made irregular by having sections curved in one direction alternating with sections curved in the opposite direction, the sections being defined by vertical slits or incisions in the cell edges.

Abstract: 1529367 Addressing memories PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Dec 1975 [9 Dec 1974] 49998/75 Heading G4A In a storage system in which modules 10-25 (Fig. 3) in a memory 9 are addressable in a first sequence by binary address signals, when a module is found to be faulty its address signals are used to invert selected bits of the address signals for all the other modules to render them addressable in a second shorter sequence with the faulty module being assigned an address outside this sequence. As described for a 16 module memory the first faulty memory module results in the inversion of the address bits of other modules where the address bit of the faulty module is 0, i.e. if the faulty module has the address 1010 this is stored and the second and fourth bits of all addresses are inverted. If a second module is subsequently found to be faulty, e.g. the module with address 1101, its address is compared with the stored address to find the most significant bit differing, i.e. the second bit and the subsequent bits of the second faulty module, i.e. 01 are used to replace the corresponding bits of the stored address so that a new address 1001  is stored and used to control subsequent addressing. When an error is detected, the signal on line 40 (Fig. 4) clocks bi-stables 72-75 so that the address of the faulty module in Register 2 is stored in them. Where zero bits are stored, corresponding bits in subsequent addresses are inverted, e.g. by inverter 68 and AND gate 47. Where a second error is detected AND gate 54 is enabled to prime AND gates 80-82 so that the signal from the highest exclusive OR gate 65, 66, 67 which is enabled (indicating the most significant bit differing in the two addresses) results in all the lower bits of the address in Register 2 being stored in the bi-stables. Bi-stables 77-79 are controlled by the outputs of the exclusive OR gate to indicate how many modules in the sequence may be addressed. If bi-stable 77 is set (indicating only 7 modules may be addressed) a subsequent error signal results in AND gate 56 being enabled to provide an alarm signal 42.
