Title: Improvements in or relating to evaporation heat exchangers
Inventor: CHAUSSON ANDRE
IPC: B64D13/00
Filed: 1960-07-22
Abstract: 952,858. Fluid cooling apparatus; refrigerating. SOC. ANON. DES USINES CHAUSSEN. July 22, 1960, No. 25619/60. Headings F4H and F4S. A liquid or gas flowing through tubes 5 extending through a casing 1 open to atmosphere, e.g. through a port 3, is cooled by the evaporation of a volatile liquid contained in a charge of fibrous material in which the tubes are embedded, the arrangement including a porous partition which retains the charge in place inside the container. The area of the charge directly in communication with the atmosphere through the partition, may be increased by the provision of ducts extending through the charge material. In Fig. 1 the partition comprises a grid 10. In Fig. 6 the charge is contained within a perforated casing 1 itself contained within an outer casing 1. Liquid sufficient only to be absorbed by the charge material is introduced through nozzle 13, any surplus being removed through a drain duct 14. The introduction of additional liquid when necessary, to make up losses, for example, may be controlled by a thermostat sensitive to the temperature of the fluid to be cooled passing through the tubes. In an aircraft the thermostat may also operate a warning lamp or safety device. The fibrous material may comprise felt or glass fibre the fibres of which may be woven or plaited and the absorbent or other characteristics of the material may vary in different zones of the tube nest, some zones being adapted for storing liquid and other zones being adapted to withdraw liquid from the storing zones and direct it towards the tube surfaces (see e.g., Fig. 5, not shown). Suitable volatile liquids mentioned are distilled water with or without the addition of a liquid modifying its boiling-point, alcohols and ethers. The tubes may be provided both internally and externally with extended heat-exchange surfaces (Figs. 3, 4, not shown).

Title: Modular heat exchanger with pivotal cores
IPC: F28D1/053
Filed: 1976-06-21
Abstract: 1489030 Heat exchangers CATERPILLAR TRACTOR CO 21 June 1976 [9 Oct 1975] 25651/76 Heading F4S An assembly 10 comprising a plurality of heat exchange core units 48 extends between a main inlet header 44 and a main outlet header 46, each core unit having first and second faces facing respectively in opposite directions and being pivotally mounted about an axis extending between the two headers, the amount of pivoting permitted for each core unit being such that in one limiting position (shown in full lines) the first face of each core unit is exposed in use to a stream of cooling air and in the other limiting position (shown in dotted lines) the second face of the core unit is exposed to the stream of cooling air. Hence the direction of cooling air flow through the cores is reversed relatively when the cores are changed from one position to the other, whereby any accumulation of debris such as wood chips, leaves &c. on the leading face of the core is removed. In the form shown, the assembly 10 and also a similar but smaller core unit assembly 88 comprise the cooling system for a liquid-cooled I.C. engine 26, the assemblies 10 and 88 being positioned behind removable grilles 22, 24, and 94. Stops such as 78 limit the pivotal movement of the core units which can be secured in their limiting positions by pins 86, Fig. 2. Alternatively a linkage may interconnect the cores for simultaneous movement by an actuator. Additional cores may be provided to cool oil from an hydraulic drive. The core assemblies shown are disposed in a zig-zag arrangement and a gap may be left between adjacent cores (see Figs. 3 and 4) to carry away debris. Each core pivot 58 is a hollow member conveying fluid (e.g. engine coolant liquid) between the core and the header. Alternatively the fluid connections between each core and the headers may comprise flexible tubes (100, Figs. 3, 4).  Each core unit preferably comprises a plurality of finned tubes, extending between headers 54, 56, Fig. 2.

Title: Bleach-fast orange to red azo dyes
IPC: C09B39/00
Filed: 1960-07-27
Abstract: The invention comprises dyes of formulae <FORM:0918416/IV (b)/1> and <FORM:0918416/IV (b)/2> where n is 0 or 1 to 3, Z is Me or Et, J1 and J2 are H. Hlg, Alk or Oalk of 1-4 C atoms, there being not more than 1 Hlg atom in each benzene ring, R and R1 are fibre-reactive links and G is a radical of formula <FORM:0918416/IV (b)/3> where M is a water-soluble cation and A and C may bear substituents other than hydroxy and basic amino radicals and A is also free of alkoxy groups. The dyes are made by conventional diazotisation and coupling processes, compounds corresponding to G being made by diazotising, e.g. a 4-nitroaniline-2-sulphonic acid and coupling with a 2-naphthylamine-3-sulphonic acid, and the product is reduced to give an amino group prone to the azo group, which may be diazotised and coupled, and this process may be repeated according to any amino groups in the coupling components, and the amino azo dyes thus obtained are treated with bifunctional fibre-reactive compounds such as cyanuric chloride or a dichlortriazine of formula <FORM:0918416/IV (b)/4> where Q is, e.g. hydroxy, amino, bis-hydroxyalkylamino, N-alkarylamino, aryloxy, thioalkyl or sulphonated or carboxylated derivatives thereof.  Compounds corresponding to Q may also be made by treating a compound of formula <FORM:0918416/IV (b)/5> where M and Z are as above, and X1 is a substituent, with an acylating agent, e.g. benzoyl chloride or p-toluene sulphochloride, reducing, diazotising and coupling with the required naphthalene components, hydrolysing and introducing the fibre-reactive link.  Two mols of dye may be reacted with one mol of cyanuric chloride to produce polyazo dyes.  Indicated substituents for A are halogen, SO3M, alkyl or COOH and for C are as for A with the addition of alkoxy.  Representative of bifunctional fibre-reactive compounds used in addition to those already indicated are o-nitro-and-chloro-and-p-sulphophenyl-, a -naphthyl and o-biphenyl-chloroformates, 2,4,6-tri- and 2,4,5,6-tetra-chloropyrimidines, b -chloropropionyl chloride, acrylyl chloride, b -sulphatopropionyl chloride, chloroacetyl chloride and b -bromopropionyl bromide.  The dye intermediates obtained before reaction with the fibre-reactive compound and containing, in a benzene ring, an amino, or substituted amino group, or nitro group, in the para position to an azo group, are also useful bleach-fast dyes and colour, e.g. cotton, wool and nylon.  The fibre reactive dyes react with fibres containing OH, NH and NH2 groups, e.g. cotton, wool, silk and nylon. Orange and red dyes or prints are obtained. Examples are provided of the preparation of the dyes and their use in colouring processes.  Reference has been directed by the Comptroller to Specifications 797,946 and 868,492.

Abstract: 674,608. Batteries. AMERICAN HARD RUBBER CO. Oct. 26, 1950 [Nov. 4, 1949], No. 26119/50. Class 53. An accumulator is provided with a filling opening which is normally closed by a plug which can be raised vertically, but not entirely removed, and then swung about an eccentric pivot to expose the opening. A tube depending from the filling opening into the container limits the quantity of liquid that can be introduced, a gas vent leading from the space above the electrolyte being simultaneously closed when the filling plug is swung to the open position. Fig. 1 shows a plug comprising three parts 24, 30, 31, the parts 24, 31 being secured rigidly together while the part 30 is free to rotate within the part 24. The part 24 is provided with bosses 26 which engage in bayonet slots 27 in a tubular portion 21 of the battery cover 20. A second tubular portion 40 depends from the cover to the required electrolyte level. The member 30 is provided with a pin 34 which can rotate in a tubular bearing 35. To remove the plug the part 24 is rotated to free the bayonet catch and then lifted till a projection 37 on the pin 34 abuts against the bearing 35. All the parts of the plug are then swung together clear of the filling opening about the axis of the pin 34. A screw thread may be used instead of the bayonet catch 26, 27. In the position of the parts shown in Fig. 1 gas can escape from the battery through holes or a slot 46 in the bearing 35 and a slot 48 in the pin 34. The slot 48 communicates with a second slot 47 from which gas can escape through a space 42 and holes 43, 44. In the position shown in Fig. 3 the slot 48 is cut off from the slot 46. The lower end of the pin 34 is bifurcated to enable the two parts to be pinched together when the pin is to be inserted in or removed from the bearing 35, Fig. 7, shows a modification in which the parts 56, 60, 55 and the pin 34 are secured together and can be rotated as a whole in the plug part 59. In a further modification the part 60 is replaced by a tubular member depending from the part 56 and embracing the enlarged end of a pin projecting upwardly from the part 55. The parts 56, 59 are formed integrally and when unscrewed from the battery cover 21 can be raised to lift the part 65 and pin 34. Fig. 10 shows a further modification in which the plug 82 carries a hollow bifurcated stem 89 having projections 91 at its lower end which engage under flanges 92 formed on a tubular part 86 of the battery cover. When the plug is lifted the projections 91 snap past the flanges 92 and engage stops 94. The plug can then be rotated about the axis of the stem. 89.
