Title: Absorption refrigeration apparatus
IPC: F25B15/06
Filed: 1976-02-09
Abstract: 1500841 Absorption refrigeration apparatus ARKLA INDUSTRIES Inc 9 Feb 1976 [13 Feb 1975] 04941/76 Heading F4H An absorption refrigeration apparatus utilizing water as the refrigerant and either lithium iodide or lithium bromide as the absorbent, comprises a vapour generator 8 disposed in the upper part of a condenser vessel 13, and a unitary annular-shaped absorber-evaporator vessel 30 which surrounds the condenser vessel. Refrigerant vapour boiled off in the generator 8 condenses on the inside wall of the condenser 13 and collects in a sump at the base 26 of the condenser. The refrigerant then passes under pressure in a conduit 41 to a channel 40 at the top of the evaporator portion of the vessel 30, to flow downwardly over a coil 35 containing water to be cooled; whereupon the refrigerant vaporizes. The hot strong absorbent solution left in generator 8 flows over a partition 15 into conduit 27. The solution passes to the top of vessel 30 and into a channel 31, which with a restriction 33 forces the solution to flow over the inside walls of the vessel 30. Refrigerant vapour driven off in the evaporator portion dissolves in the absorbent solution and the resulting refrigerant-enriched absorbent solution collects in the bottom of the vessel 30. A pump 16 pumps the solution back to the generator 8. The absorbent solution, leaving the generator 8 in conduit 27, passes in heat exchange contact with incoming refrigerant-enriched absorbent solution in pipe 17 in heat exchanger 18. The apparatus is housed in a casing 50 having an air inlet 56 and an air outlet 53. A fan 51 forces air through the casing. A water reservoir 60 is located in the base of the casing, the water being pumped by a pump 61 through a conduit 62 to spray over the condenser vessel 13 and the absorber-evaporator vessel 30.

Abstract: 286,227. I. G. Farbenindustrie Akt.- Ges. Feb. 27, 1928. Samples furnished. Trisazo dyes are obtained by tetrazotizing a diaminoazo dyestuff obtained by diazotizing 5- nitro- or 5-acetylamino-2-aminobenzoic acid, coupling with a diazotizable middle component and reducing or saponifying, and coupling with a component (2 mols.).- The resulting dyestuffs may be after-treated with metallic salts on the fibre. Those containing free amino groups may be subjected to diazotization and coupling on the fibre. The following examples are specified. (1) The nitro group of the monoazo dyestuff 5-nitro- 2-aminobenzoic acid # (alkaline) 2-amino-8- naphthol-6-sulphonic acid is reduced, and the product is tetrazotized and coupled with m-phenylenediamine; the resulting trisazo dyestuff yields on cotton greenish-black dyeings of which the fastness to washing and light may be increased by after-treatment with metallic, e.g. copper, salts. (2) The tetrazo compound in (1) is coupled with 3-aminophenol; the trisazo dyestuff yields on cotton greenish-black dyeings which become redder on after-treatment with coppersalts. (3) The acetyl group of the monoazo dyestuff 4-acetylaminoaniline-3-carboxylic acid # (alkaline) 2-amino-8- naphthol-6-sulphonic acid is split off, and the product is tetrazotized and coupled with mtoluylenediamine ; the trisazo dyestuff yields on cotton black dyeings of which the fastness may be increased by after-treatment with copper salts. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the production of disazo dyes by diazotizing an aminoazo dyestuff derived from an arylene diamine carboxylic acid and coupling with a component and of trisazo dyes by tetrazotizing a diaminoazo dye similarly derived and coupling with a component, the coupling being preferably effected in the presence of a tertiary base. After-treatment of the dyestuffs with metal salts in substance is also mentioned. The following examples are given :-(1) the reduced dyestuff 5-nitro-2-aminobenzoic acid # (alkaline) phenyl-J-acid is diazotized and coupled with 3 : 5-dioxybenzoic acid in presence of pyridine. The product gives a clear violet on cotton when after-chromed, (2) when phenyl-J- acid is used as end component in (1) a red violet and blue violet are obtained on after-chroming and after-coppering respectively, and (3) when 1- amino-2-ethoxynaphthalene-6-sulphonic acid is used as end component in (1) a reddish-blue and greenish blue are obtained. This subject-matter does not appear in the Specification as accepted.
