Patent GB-676647-A (GB)
Title: Improvements relating to dyeing with complex copper compounds
Filed: 1949-09-30
Abstract: Dyebaths are prepared by dissolving in water a metal-free dyestuff that dyes cellulosic material and forms a difficultly soluble copper compound, adding thereto excess of ammonia or an aliphatic base and, at the same time or subsequently, such a copper compound as contains the copper in complex form in the anion or else a copper salt together with a complex former capable of binding the copper in the anion.  Preferred dyestuffs are those which contain at least two azo groups and at least once the grouping <FORM:0676647/IV (c)/1> where X is hydroxyl or carboxyl, particularly in the form <FORM:0676647/IV (c)/2> where Y is an azo, azoxy or urea group or a direct linkage. Alternatively there may be used derivatives of 4 : 41-bis-(411-arylazo-pyrazonyl-111)-diphenyl or -stilbene.  Suitable dyestuffs are listed.  The aliphatic base is preferably such as cannot be removed with steam and may be an aliphatic amine or a morpholine base, suitable compounds being mentioned (especially monoethanolamine and ethylene diamine).  The complexing agent for the copper is preferably an aliphatic hydroxycarboxylic or aminocarboxylic acid, e.g. glycine, alanine, or glycollic, lactic, hydracrylic, tartaric, citric or b -hydroxybutyric acid.  The dyebaths so obtained may be used for dyeing materials that do not require acid conditions, e.g. linen, cotton and regenerated cellulose; normal methods are applicable. Examples are given of the preparation of dyebaths and the dyeing of cotton therewith.  The dyeing may be after-treated with the condensation product of dicyandiamidine and formaldehyde. Specification 455,274 is referred to.  According to the Specification as open to inspection under Sect. 91, the copper need not be in complex form in the dyebath but in this case there is preferably added a dispersing agent, the use of sodium N-methyl-m -heptadecyl-benzimidazole sulphonate being exemplified. Also, the organic base need not be aliphatic and the components of the dyebath need not be added in the above order.  This subject-matter does not appear in the Specification as accepted. Specification 458,501 also is referred to.

Title: Improvements relating to biscuit handling equipment
Inventor: MORTON DAVID CHARLES
IPC: A21C15/00
Filed: 1962-07-02
Abstract: 1,016,026. Endless conveyers. BAKER PERKINS Ltd. Sept. 19, 1963 [July 2, 1962], No. 25276/62. Heading B8A. Equipment for handling flat articles arriving in rows from lanes 3 on a horizontal endless conveyer 1 comprises guides 11 mounted above the conveyer to define channels, deflectors 14, 15, 16 pivotally mounted adjacent the entrances of these channels for guiding the articles into one or other of two adjacent channels with a timing according to the relationship between the number of rows of articles reaching the channels and the number of channels, such that substantially equal numbers of articles are guided into each channel. In the embodiment shown, articles are delivered by eleven lanes 3 for passage into four channels formed by the guides 11. The deflectors 14, 15, 16 are slidably pivoted at 18 to a cross-bar 12 secured at 13 to framework 6. Actuation of the deflectors is effected by rods 20, 21, 22 driven by bell-crank levers 23 which are actuated by cams 24 which actuate the deflectors abruptly. The latter are adjustably secured to a common shaft 25 driven through a chain and gear-box by a motor 27. In one cycle of operation initially all the channels receive three lanes of articles except the channel outwardly of the deflector 16 which receives two lanes. The deflector 16 then pivots to allow three lanes of articles to pass into the outer channel and only two lanes of articles into the channel between deflectors 15, 16. The deflectors 15, 14 are then actuated similarly and then the procedure reverses across the conveyer. Since for every complete cycle the outer channels have only one turn at receiving two lanes of articles against the two turns each of the inner channels, the timing of the deflector operation is set to ensure a substantially even distribution of the articles into the channels. In a further embodiment, Fig. 3 (not shown) ten article delivery lanes are permanently divided into two. sets of two deflectors controlling entrance to two sets of three channels. Like deflectors in each set are operated by a common rod.

Title: An improved tap, and automatic cut off
IPC: G07F15/00
Filed: 1920-09-02
Abstract: 164,644. Duncan, W. F. Sept. 2, 1920. Safety cut-off valves.-A safety-valve for use with prepayment gas meters is kept open by the gas flow but must be re-opened by hand when once closed. A conical plug A provided with a handle H operates in a casing composed of three portions D, C, D, and a cross bore G is formed in the plug. A longitudinal bore E contains a loose plug F which is slightly conical. When the plug A is turned from its off position, the passage G and then the grooves M are opened to the port K. Gas passes through the grooves M to the space N and lifts the plug F, which has previously been moved from its seating by a cam-shaft L formed on the bottom of the casing. Gas from the inlet I is then free to pass through the passages G, E, to the outlet J. When the flow of gas ceases, the plug F falls back and the passage is closed until the above operations are repeated. When the handle H is turned to its " full on " position, the spring 0 is compressed so that when released, the plug is moved back slightly to close the grooves M and place the cam L in such a position that the plug F is free to return to its closed position when the gas flow ceases.

Title: Improvements in method of producing sodium bicarbonate and hydrogen
IPC: C01D7/18
Filed: 1920-09-02
Abstract: Sodium bi-carbonate and hydrogen are obtained in a modified ammonia-soda process by using carbon-dioxide mixed with hydrogen as a diluent, instead of with nitrogen.  The required gaseous mixture is preferably prepared by passing water-gas together with steam over a catalyst at an elevated temperature in the known manner, to convert the carbon-monoxide to di-oxide.  In practice, it is found necessary to remove the small quantity of sulphuretted hydrogen in the water-gas before the oxidation of the carbon-monoxide therein, and this is effected by passing it through one or more of the iron-walled carbonating-towers which are thereby protected at the same time by the resulting ferrous sulphide deposite upon them.  The issuing gases are then passed p  through the contact-chamber and the resulting carbon-dioxide and hydrogen bubbled through a second series of carbonating towers to precipitate sodium bi-carbonate.  The unabsorbed gas consists of substantially pure hydrogen and is used in the synthesis of ammonia.  The water-gas may be enriched with carbon-dioxide obtained by calcining the sodium bicarbonate after removing the water-vapour present, by condensation.
