Title: Process for preparing symmetrical and unsymmetrical carbocyanine dyes and merocarbocyanine dyes
IPC: C09B23/06
Filed: 1958-04-02
Abstract: In the process of preparing carbocyanine and merocarbocyanine dyes from quaternary salts of the formula:-(IV) <FORM:0871930/IV(c)/1> and an ortho ester of formula (V):-R1-C(OR2)3 (wherein R is an alkyl or substituted alkyl group, R1 is H or an alkyl group, R2 is an alkyl group, X is an anion and Z completes a 5- or 6-membered heterocyclic ring), the reaction is carried out in tricresyl phosphate or a phenol as reaction medium and in the presence of an alkali metal hydroxide or an organic tertiary amine having a dissociation constant greater than pyridine as basic condensing agent.  The symmetrical carbocyanines are prepared from 2 mols of (IV) and one mol of (V). The compounds (IV) and (V) may first be heated together in the reaction medium and then the basic condensing agent added and the heating continued.  The unsymmetrical carbocyanines are prepared from 1 mol of (IV), one mol of (V) and 1 mol of heterocyclic base of the formula:-  <FORM:0871930/IV(c)/2> (where R1 and Z1 have the same meanings as R1 and Z above).  The dye base may first be formed by treating the corresponding quaternary salt with the basic condensing agent, and the preformed base is then added to a reaction mixture made by heating (IV) and (V) in the reaction medium; no more basic condensing agent is then required.  The merocarbocyanine dyes are prepared from 1 mol (IV), 1 mol (V) and 1 mol of a compound:- <FORM:0871930/IV(c)/3> (where Q completes a 5- or 6-membered heterocyclic ring).  The reaction medium may be o-, m- or p-tricresyl phosphate, o-, m- or p-cresol or phenol.  The basic condensing agent may be triethylamine, tri-n-propylamine, tri-n-butylamine, N; N-dimethyl aniline, N; N-diethyl aniline, N-methyl piperidine or N-ethyl piperidine.  Examples are given of the preparation of symmetrical meso-substituted carbocyanine dyes from ethyl orthoacetate or ethyl orthopropionate, of unsymmetrical meso-substituted carbocyanine dyes from ethyl orthoacetate and of merocarbocyanine dyes from ethyl orthoformate or ethyl orthoacetate.

Title: Improvements in or relating to electric water heaters
Inventor: HALL WILLIAM EDWARD THOMAS
IPC: F24H1/20
Filed: 1955-04-15
Abstract: 799,096. Electric water heaters. GENERAL ELECTRIC CO., Ltd. April 16, 1956 [April 15, 1955], No. 10901/55. Class 39(3) An electric water heater of the storage type comprises a tank having upper and lower thermostatically controlled heating elements. The thermostat of the top element is arranged to control the temperature so that it cycles around a certain predetermined limit, and the thermostat of the bottom element is arranged for "once only" operation, and is adjusted so that, when energized, the bottom element raises the temperature of all the water in the tank above the said pre-determined value. As shown, a tank 1, suitably lagged, has in its top a head 3 carrying two heating elements 4 and 5. The shorter element 4 heats the water in the top of the tank to a predetermined value-say 140‹F. and its control thermostat 6, of the cycling type, maintains this temperature. The longer element 5 may heat all the water in the tank, but its control thermostat 7 is arranged for "once only" operation, and is so adjusted that the element 5, when energized, will raise the temperature above that maintained by the shorter element, to a value of say 160‹F. Thermostat 7 is associated with a push button 8 which normally holds the thermostat in the "off" position. Operation of the push button energizes element 5, the thermostatoperating to release the button and de-energize the element when the higher temperature is reached. When the water temperature drops, the thermostat 7, being held in the "off" position, will not switch on again unless the button is once more depressed. The button 8, however, may also be arranged so that if desired it can be locked in its depressed position to allow the longest element 5 to cycle.
