Title: A process for increasing the wetting-out power of mercerising lyes
IPC: D06M11/38
Filed: 1939-01-04
Abstract: 523,549. Wetting &c. agents; mercerizing processes. ELLIS, G. B. (Chemical Works, formerly Sandoz). Jan. 4, 1939, No. 287. [Classes 2 (iii) and 15 (ii)] The wetting power of mercerizing lyes is increased by adding thereto a polyethermonocarboxylic acid or an alkalimetal. organic ammonium or amino salt thereof of the general formula R (OR 1 )nOR 2 COOH wherein R is an aliphatic radicle or a cycloaliphatic radicle which does not contain more than nine carbon atoms, R 1  and R 2  are alkylene radicles and n is a positive integer. The wetting agents may be used in association with known assistants such as phenols, aliphatic carboxylic acids having 4 to 9 carbon atoms, alkoxyacetic acids, naphthenic acids, highly sulphonated oils, sulphuric esters and alkylated aromatic di and polysulphonic acids. They also emulsify in the alkali lye assistants such as hydrocarbons, alcohols, ether-alcohols, ketones, acetals, and nitrogenous bases such as aliphatic amines and hydroxy amines. In examples the following compounds or mixtures are used in mercerizing lyes: (1) n-butoxyethoxvacetic acid in admixture with (a) the condensation product of glycide with di-#-oxyethylamylamine, (b) naphthenic acid and xylenylglycerine ether, (c) naphthenic acid, sodium isoamyloxyacetate and xylenylglycerine ether, (d) technical xylenol and (e) iso-amyloxyethoxy acetic acid and di-#-oxyethylamylamine, (2) #-(#<SP>1</SP>-n-butoxyethoxy) ethoxyacetic acid and the corresponding α-oxypropionic and α-oxybutyric acid derivatives, (3) iso-amyloxyethoxy acetic acid and (a) xylenylglycerine, (b) the mixture of acetates obtainable from the methylcyclohexanones and glycerine, (c) high boiling technical xylenol, (d) n-butyl sulphuric acid ester, (e) ethyleneglycolmono-n-butylether sulphuric acid ester, (f) cymenesulphonic acid, (f) diethyleneglycolmono-n-butylether and the sulphonated mixture of laurylalcohol, cresol and isoamylalcohol, (g) the product obtained by sulphonation and condensation of #-naphthol and isoamylalcohol, (4) #-(#<SP>1</SP>-n-butoxyethoxy) ethoxyacetic acid and isovalerianic acid, (5) ethylbutoxyethoxyacetic acid (6) octyloxyethoxyacetic acid, (7) sec. amyloxyacetic acid, (8) isopropoxyethoxy acetic acid and diethanoln-butylanine or diethyleneglycolmono-n-butylether. Specifications 427,899 and 452,866 are referred to. Polyethermonocarboxylic acids having the above formula may be prepared by condensing the alkali salts of mono or polyetheralcohols with monohalogen alkylcarboxylic acids. Thus, isoamyloxy ethoxyacetic acid is prepared from monoisoamylglycolether sodium salt and monochloracetic acid.

Title: Continuous casting method and apparatus therefor
IPC: B22D11/12
Filed: 1974-01-04
Abstract: 1454052 Continuous casting NIPPON STEEL CORP 4 Jan 1974 [18 April 1973] 329/74 Heading B3F In the continuous casting of a metal slab 21, e.g. of steel, the molten core 23, within the shell 22 of the solidifying slab is agitated in a direction, perpendicular to the direction of casting by a travelling electromagnetic field produced by an inductor 31, whereby dendritic crystal growth and segregation effects are inhibited and a casting having a substantially equiaxed crystal structure is produced. The length of the agitation zone is less than the width of the casting. The inductor 31 is energized with alternating current at a frequency less than 20 Hz and is positioned at a point at least three metres from the surface of the the molten metal in the mould 14 which, as shown, is associated with an immersed nozzle 13 leading from a tundish 12. The arrangement is such that the metal in the agitation zone is caused to move first in direction A and then in direction B at a speed which is more than ten times greater than the speed of the metal flowing from the nozzle 13; moreover, the area near each short side of the shell 22 constitutes a dead zone, in which the metal is not acted upon by the electromagnetic force, so that the agitated metal does not hit the shell at a high speed. The inductor 31 is supplied with a coolant such as water and its housing is non- magnetic, as are the guide rolls 18, 19 adjacent the inductor. Further non-magnetic guide rolls (55, 57), Fig. 20 (not shown), are provided in association with the inductor, the rolls (55) closest to the agitation zone being of smaller diameter than the other rolls. Reference has been directed by the Comptroller to Specification 1,305,414.

Loose concrete blocks C' are disposed beneath the cover B<2> opposite to the ribs B<1> and spaced from the ribs by the width of the metal strip C from which the resistance element is formed. Each resistor C is formed of a strip of expanded metal bent into zig-zag formation so that each turn is supported by its edges between the ribs B<1> and blocks C<1>. The whole space within the casing is filled with sand or other granular, powdered, or fibrous heat absorptive material. The ends of the element C are connected to terminal tabs C<3> extending through recesses between the base B and the cover B<2>, the tabs being held in position by bolts C<4> embedded in the concrete of the base B. The joint between the cover and the base is sealed by a soft weatherproof sealing composition D. A number of separate lengths of expanded metal may be joined at alternate ends or otherwise interconnected to form a network. A number of units are assembled one above another to form a stack, the base B being provided with feet. B<3> so that its lower surface is slightly spaced above the cover B<2> of the next lower unit. The resistor elements in a stack are connected in series by interconnecting straps. Several such stacks may be connected in series, parallel, or series-parallel, between the neutral point of a supply system and earth-.in order to carry large neutral currents during earth fault conditions. A separate cover for each unit may be dispensed with, except at the top of a stack, the base of one unit being shaped to fit on top of the next lower unit with a weatherproof joint.

Title: A Process of and Apparatus for the Continuous Nitration of Organic Liquids.
IPC: C07C201/08
Filed: 1917-01-08
Abstract: 126,355. Clayton Aniline Co., Schedler, A., and Vuilleumier, V. Jan. 8, 1917. Nitro compounds.-The continuous'nitration of organic liquids is carried out in a plant consisting of (1) a series of open measuring tanks containing the nitric acid, sulphuric acid, liquid to be nitrated, and water for dilution if necessary, the base areas of the tanks being proportional to the requisite volumes of the several liquids, (2) reaction pans of uniform size and shape arranged in a stepped series and provided with agitators, (3) a separator into which the product of reaction flows and separates into nitro body and waste acid which flow off from the top and bottom respectively to suitable receptacles. The two acids are run continuously from their measuring-tanks into the top reaction pan and are mixed therein; the mixture flows down to the next pan into which the liquid to be nitrated is also running from its measuring tank; the reacting mixture flows down through as many pans as are necessary to complete the reacton, and finally (after dilution with water if necessary) the product flows into the separator. The drawing shows an arrangement suitable for nitrating toluene to mononitrotoluene; the tanks R', R<2>, R' contain respectively sulphuric acid, nitric acid, and toluene; the two acids are run into the pan P' and after mixing run into pan P<2>, which also receives toluene from tank R<3>; the mixture then flows through pans P<3>, P<4>, to the separator T; the temperatures in the several pans are suitably adjusted by heating or cooling coils. A similar arrangement, using four measuring tanks and seven reaction pans, is described for nitrating a mixture of mono-, di-, and tri-nitrotoluene to trinitrotoluene. Details of quantities of reagents, temperatures, &c. in these two processes are given. The process and plant may also be applied to the continuous nitration of benzene to mono- or di-nitrobenzene, xylene to mono- or di-nitroxylene, chlorbenzene to mono- or di-nitrochlorbenzene, &c. Specification 16836/10, [Class 86, Mixing &c.], is referred to.

Abstract: 883,201. Television cameras. PYE Ltd. Jan. 8, 1958 [Jan. 8, 1957], No. 773/57. Class 97(1). The iris diaphragm is operated through a transmission drive having a non-linear characteristic such that the angular movement of the iris diaphragm control required to produce unit angular change in the drive ring of the iris diaphragm increases towards positions of the iris diaphragm corresponding to small apertures, so that there is a linear, or substantially linear relationship between the movement of the control and the light transmitted through the iris diaphragm. Thus the diaphragm ring 1 may lie driven from a gear 2 driven in turn through non-linear gearing 3, 4. In another form the non-linear gearing drives the diaphragm ring directly. The control of the diaphragm may be effected manually or through a servo-mechanism. The Provisional Specification refers also to the use of a non-linear mechanism in the control of focusing or of a guy wedge.
