Title: Process for the preparation of complex cobalt and nickel compounds of water-insoluble azo-dyes on vegetable fibres
IPC: D06P3/68
Filed: 1961-01-16
Abstract: Complex cobalt and nickel compounds of water-insoluble azo dyes are prepared on vegetable fibres by coupling a diazorium compound of an 8-amino-quinoline on the fibre with a coupling component which couples in a position adjacent to a hydroxyl group, with the exception of the arylamides of aromatic or heterocyclic ortho-hydroxy-carboxylic acids or of acylacetic acids, the diazo and coupling components being free from carboxylic and sulphonic acid groups and treating the dyestuff so obtained with a cobalt- or nickel-yielding agent.  The metal-free dye may be formed on the fibre and the dyeing subsequently treated with a metallining agent, or the coupling component applied to the fibre which is then developed in a bath containing a diazotised 8-aminoquinoline and a cobalt or nickel compound.  In examples: (1) cotton fabric is padded with an alkaline paste of b -naphthol, dried and developed in a bath containing diazotised 8-amino-6-methylquinoline and nickel sulphate to give a red-violet dyeing: (2) the dye 8-amino-2-methylquinole-->b -naphthol is prepared on a cotton fabric in the usual way and then treated with a solution containing nickel sulphate to give a violet dyeing. Further dyeings are specified in a Table.

Title: Process and apparatus for continuous plate-type evaporation
IPC: B01D1/22
Filed: 1960-01-19
Abstract: Soap slurries, fruit juices and other liquids are concentrated by evaporation without foaming by feeding the material into a tortuous flow path of relatively narrow cross-section elongated in a direction lateral to the flow of the material, the flow path having preselected variations in its cross-section, passing the material through the flow path while supplying heat to release vapour from the material, the rate of feed and the heat supplied being so as to obtain a high rate of evaporation and a high velocity of the mixture through the flow path thus inhibiting deposition of concentrate upon the surfaces which defines the flow path.  Reference is made to the removal of solvents from oils, and the separation of alcohol from water.  In a preferred embodiment using a plate-type evaporator the material to be evaporated is pumped from a supply tank 10 via line 14 into the evaporator through an inlet 16.  The evaporator is formed from a plurality of plates 17 arranged in spaced relationship by gaskets 18 held together in frame 15 by a compression means 19.  The spaces between the plates alternately form flow channels for the liquid-to-be-evaporated and the heating-medium.  The first plate of each channel for the liquid being evaporated has an inlet port 21 and the next adjacent plate thereto has an outlet port 22.  The number of flow channels for the liquid increases, in the direction <PICT:0935542/III/1> of flow, from one to four.  Preferably the ports increase in cross-sectional area towards the final outlet port which exits to a line 24 which conveys the product to a separator 25 which has a vapour overhead take-off line 26 and a draw-off pipe 27 for removing the concentrate product.  In another embodiment, the mixture of liquid and vapour can be tapped off from an intermediate channel and led to a separate separator.  The separated liquid can then be fed back to the next channel; and the separated vapour can be used to provide heat for evaporation in the second stage.

Patent GB-794067-A (GB)
Title: Improvements in the preparation of alcohols
Inventor: REED HUGH WILMA BOULTON
Filed: 1956-01-20
Abstract: Alcohols are prepared by reacting olefines, water and carbon monoxide at superatmospheric temperature and pressure in the presence of a "suitable" base, iron pentacarbonyl and, as initiator, hydrogen or a salt of iron hydrocarbonyl.  The "suitable" bases are defined as those sufficiently strong to catalyse the reaction between iron pentacarbonyl and water to form iron hydrocarbonyl but not so strong as to form a stable carbonate.  The preferred bases are organic tertiary amines, e.g. trimethylamine, dimethylaminoethanol and N-n-butylpiperidine. Suitable salts of iron hydrocarbonyl for use as initiators are, for example, sodium and potassium iron carbonylate, trisethylendiamine-nickel iron carbonylate, biscyclo pentadienyl-iron iron carbonylate, biscyclopentadienyl-vanadium iron carbonylate and biscyclopentadienyl-titanium iron carbonylate, and they may be added as such or in solution or suspension in a suitable medium. Mono-olefines or di-olefines may be used as starting materials and the process may be carried out batchwise or continuously.  The preferred temperature range for the process is 100-200 DEG  C. and the preferred pressure range is 100-400 atmospheres.  In the example propylene is treated at elevated temperature and pressure with water and carbon monoxide, in the presence of iron pentacarbonyl, one of the bases trimethylamine, dimethylamino-ethanol and N-n-butylpiperidine, using as activators hydrogen, trisethylenediamine-nickel iron carbonylate, biscyclopentadienyl-iron iron carbonylate, biscyclopentadienyl-vanadium iron carbonylate, biscyclopentadienyl-titanium iron carbonylate and sodium iron carbonylate, to give butanols.

Abstract: 1450473 Automatic control of pressure CONSIGLIO NAZIONALE DELLE RICERCHE 16 Jan 1974 [16 Jan 1973] 01983/74 Headings G3N and G3R Apparatus for controlling hydraulic pressure, e.g. pressure in a cylinder 9 under test, comprises a comparator 5 which receives an electrical reference signal from a generator 6 indicating the desired pressure and an electrical feedback signal from a transducer 7 indicating the actual pressure, the comparator output being fed to a device 4 producing a control pressure differential which is applied across a piston head 14 to displace the piston in cylinder 2 and thus adjust the test pressure until the comparator output is reduced to zero. As shown the device 4 is a servovalve which receives pressurized hydraulic fluid from a source 1 and directs the fluid through one of two ducts 10a, b. The enlarged head 14 of the piston relative to the stem 15 produces amplification of the applied pressure. Loss of hydraulic fluid past the head 14 is made up through a duct 16 which is uncovered when the piston is in its extreme rear position. Fluid is also introduced to the cylinder 9 through a pipe union 13. If the cylinder 9 ruptures, the output of the comparator 5 exceeds a limiting value and the fluid source 1 is isolated. The generator 6 is a function generator producing a signal which corresponds to a desired test cycle, the number of applied cycles being counted by a logic circuit (not shown). The reference signal may alternatively be constant or manually variable.

Abstract: 590,625. Endless - chain conveyers. MELVIN & GILLESPIE, Ltd., and HALL, W. A. Jan. 29, 1945, No. 2208. [Class 78 (i)] A conveyer comprising two endless parallel chains is provided with means for loading each chain which is so arranged that if one chain is stretched more than the other, the tensioning load on the first chain is transferred to the second, thus relieving the first chain of tension and applying a double stretching load to the second chain, thereby automatically preventing misalignment at least by more than a very small amount of any two initially aligned points on the two chains. In the embodiment shown in Fig. 1, the bearings 6 of the wheels 1, 2 of the conveyer chains A, B are slidably mounted on bed plates 7 and weights A<1>, B<1> are suspended from chains 8<1>, 8 attached to the bearings. The weights are of equal magnitude and the weight A<1> is arranged in the weight B<1> with gaps of “ inch or ¢ inch between. Rods 11 fastened to the conveyer frame guide the weight B<1> whilst rods 12 attached to the weight Bi maintain the weight A<1> in correct transverse spaced relationship to the weight B<1>. If the stretch of chain A exceeds that of B by an amount greater than the gap 10<1>, the load of both weights is transferred to chain B and the latter chain may now stretch until the top of weight B<1> rests on weight A<1> when the combined load is now transferred to the chain B.
