Title: Improvements in or relating to eye protecting devices
IPC: A61F9/06
Filed: 1931-08-21
Abstract: 386,350. Eye protectors. KANNENBERG, K., 6, Alte Jakobstrasse, Berlin. Aug. 21, 1931, No. 23569. [Class 97 (i).] An eye protector, particularly for welders' use, comprises a mask which fits over the face and has an opening opposite the eyes, which can be covered at will by a rotatable light filter, the rotation of the filter being effected by a lever operated by the chin, and the arrangement being such that when the chin is raised after being depressed to turn the filter, the filter remains looked in the position to which it has been moved and does not receive any further rotation until the chin is again depressed. In the form shown, the filter 3, consisting of a disc half of which is clear and the other half coloured &c., is mounted on an axis 4 outside the mask 2. The chin lever 5 is connected by a link 6 to a pivoted toothed sector 12 which is adapted to rotate a pinion 14 fixed on the axis 4 to which is also secured a ratchet wheel 15 co-operating with a pawl 16 carried by the disc 3. A trigger 7 pivoted on the link 6 is arranged to engage a slidable detent 9 which can enter one of two diametrically opposite recesses 10, 19 in a disc 11 secured to the disc 3. The first downward movement of the lever 5 causes the trigger 7 to withdraw the detent 9 out of engagement with the disc 11, leaving the disc 3 free to be rotated by the sector 12. The trigger 7 is guided by a cam surface 17 so that after a short downward movement it is withdrawn from the path of the detent 9 and the latter is moved upwards by a spring 18 into engagement with the disc 11 so that after the disc has turned through 180‹ the detent enters the recess 19 and prevents the disc 3 from rotating further. Release of the chin lever causes the operating means to be reset by means of a spring 13 while the disc 3 remains locked, so that on again depressing the chin the disc 3 can again be turned through 180‹. The mask is attached to the head by a flexible ring 21 made in two parts connected by a spring 23, the ring having a U-shaped attachment 24, the ends of which engage perforations in two parallel members 26 carried by the mask. The ring 21 is also connected to the mask by a spring 27. The chin lever may be provided with a laterally-extending member 46 engaging round the chin. In another form the filter is of semicircular form and is rotated by a vertically-reciprocating rack, the rack being moved upwardly to bring the filter into operative position by a downward movement of the chin and locked in position until the chin is again depressed to allow the rack to fall under the action of a spring and to move the filter into inoperative position. In this form the downward releasing movement of the chin is of considerably smaller magnitude than that required to move the filter into operative position.

Tension rods 27 suspended from member 28 carry an auxiliary cage 2 having rollers 2<SP>1</SP> which engage the outer surface of tower 1. Diametrically opposite pins 3 on cage 2 support a frame 4 tiltable by a piston and cylinder 7 mounted between pivots 4<SP>1</SP> and 7<SP>1</SP>. Supported on frame 4 there is a ring mount 5 carrying a cage 6 with a conical inner surface 35. A gear ring 9 secured to cage 6 meshes with a gear-wheel 81 rotated by a motor 8 mounted' on frame 4. Cars or seat carriers 33 are carried on the outer ends of arms 32 pivoted on tangential pivots 6<SP>11</SP> on cage 6 each arm being individually controlled from its corresponding car by means of a cylinder 31 extending between pivots 6' and 32'. In operation, the cylinder in the tower displaces cages 2 and 6 along the tower and frame 4 can be tilted by cylinder 7. Further, tower 1 can be rotated on its rollers 10 on substructure 43. In a modification, Fig. 7, the auxiliary cage 20 bears on the outer surface of the tower by means of rollers 20<SP>1</SP> and journals 22 carry a frame 23 which supports cage 6 and its attachments. A downward projection 42 from frame 23 has an inwardly directed arm 41 below journals 22 and carrying pins 24<SP>1</SP> with rollers 24. These rollers 24 engage in guide rails 21 whose upper ends are curved so that, as cage 20 moves up the tower, rollers 24 slide in guide rails 21 and, as the cage approaches the top of the curve in the rail tilts frame 23 about journal 22. In another embodiment, Fig. 3, the arm carrying cage 15 bears via a ring mount and rollers or balls 39 on an auxiliary cage 11 and projecting flange 11'. Two or four working cylinders pivoted at 25<SP>1</SP> on the lower portion 1<SP>1</SP> of the tower have piston rods 26<SP>1</SP> which engage the cage at pivots 28'. Curved guide rails 13 are mounted on opposite sides of tower 1 and receive rollers 12 and 18 to tilt the cage as it is raised by actuation of cyinders 25. The horizontal tilting axis need not intersect the vertical axis of the tower or the axis of rotation of the seat carriers. Specification 831,338 is referred to.
Patent GB-892258-A (GB)
Title: Process for preparing stable aqueous pigment dispersions
IPC: C09B67/46
Filed: 1960-07-06
Abstract: An "aqueous filter cake of an organic pigment" is mixed with a non-ionic polyglycol ether dispersant which is soluble in an acid to weakly alkaline medium but insoluble in concentrated aqueous alkalis and to the resulting mixture containing the dispersant in aqueous solution is added an amount of alkali metal hydroxide sufficient to cause the dispersant to separate from the aqueous alkaline solution and to form a separate phase. Thereafter the organic pigment is transferred by mechanical treatment into the dispersant phase, the bulk of the resulting pigment-free aqueous alkaline solution is separated and the dispersant is reconverted into an aqueous solution which contains the pigment in a very finely dispersed state. "Aqueous filter cake of an organic pigment" is defined as an aqueous cake which is alkali resistant and is obtained by filtering an aqueous slurry of a pigment resulting from the manufacture or conditioning of an organic pigment, e.g. aqueous pigment filter cakes of water-insoluble azo dyestuffs, oxazine dyestuffs, vat dyestuffs or of halogenated copper phthalocyanines.  Non-ionic polyglycol ether dispersants referred to include those made by reacting ethylene oxide with lauryl alcohol, myristyl alcohol, cetyl alcohol, octadecyl alcohol, oleyl alcohol, arachidyl alcohol, linoleyl alcohol, ricinoleyl alohol, dihydroricinoleyl alcohol, hydroabietyl alcohol, naphthene alcohol, cetylamine, octadecylamine, octadecenylamine, methyloctadecylamine, hydroabietylamine, octadecyl-p-tolindine, cetyl mercaptan, dodecyl mercaptan, hexadecyl mercaptan, lauric acid, palmitic acid, ricinoleic acid, oleic acid, p-tert.-amyl phenol, isohexylphenol, p-tert.-octylphenol, thymol, p-nonylphenol, isooctylresorcinol, 2:6-di-tert.-butyl-p-cresol, dodecyl phenol, octadecylphenol or castor oil.  The dispersant may be reconverted into an aqueous solution by (1) addition of an acid, e.g. acetic acid, (2) dilution with water or (3) addition of an anion-active dispersant, e.g. 2-heptadecyl-N-benzyl-benzimidazole disulphonate. Additionally the stable aqueous pigment dispersion may contain aminoplast resins, solvents and plasticizers.  Specified pigments are 4:41,7:71-tetrachloro-thioindigo, b -copper phthalocyanine, chlorinated copper phthalocyanine, the pigment from diazotised 2:5-dichloroaniline and 2:3-hydroxynaphthoic acid-o-methoxyphenylamide, a -copper phthalocyanine and the pigments of formulae <FORM:0892258/III/1> <FORM:0892258/III/2> <FORM:0892258/III/3> <FORM:0892258/III/4> Examples are given.

Title: Improvements in or relating to the manufacture of 1-phenyl-1.3-dihydroxy-2-aminopropane and of chloramphenicol therefrom
Filed: 1950-09-28
Abstract: 1 - Phenyl - 1 : 3 - dihydroxy - 2 - aminopropane (threo form) is manufactured by esterifying trans-b -phenylserine (e.g. by reaction with an alcohol in the presence of a small amount of a concentrated acid, if desired with removal of water by azeotropic distillation, e.g. with the aid of toluene or dichloroethane) and reducing the esterified carboxylic group to -CH2OH.  The product is advantageously isolated in the form of its triacetyl derivative, which may be converted in known manner to racemic chloramphenicol by nitration, splitting off of the three acetyl radials and dichloroacetylation of the amino group.  In examples: (1) trans-b -phenylserine is reacted with ethanolic hydrochloric acid, the ethyl ester is liberated from the resulting hydrochloride by the action of sodium bicarbonate, dissolved in ethanol and reduced with hydrogen in the presence of copper chromite, and the resulting 1-phenyl-1 : 3-dihydroxy-2-aminopropane is triacetylated with acetic anhydride; (2) the reduction in (1) is effected by treating the ester hydrochloride with sodium amalgam and hydrochloric acid in ethanol; (3) the reduction in (1) is effected by treating the free ester in ethereal solution with lithium-aluminium hydride, the excess of which is subsequently decomposed with water; (4) trans-b -phenylserine ethyl ester is reduced as in (3) and the product isolated partly as the free aminodiol by filtration and evaporation of the filtrate and partly as the N-monoacetyl derivative by extraction of the residue of lithium and aluminium hydroxides with ethyl acetate; (5) the copper chromite in (1) is replaced by Raney nickel, the reaction conditions being suitably modified; (6) racemic chloramphenicol is prepared from the product of (1), (2), (3) or (5) by nitration with fuming nitric acid, hydrolysis with dilute hydrochloric acid and dichloroacetylation with methyl dichloroacetate.  Other esters specified are the methyl and propyl esters.  Specifications 652,273, 652,275, 652,276 and 652,277 are referred to.

Title: Improvements in or relating to heat engine power plants
IPC: F02B53/00
Filed: 1935-08-26
Abstract: 440,942. Motor power plant. SHORT, J. F., North View, Nedderton, Northumberland. Aug. 26, 1935, No. 23820. [Classes 110 (ii) and 110 (iii)] The plant comprises a rotary internalcombustion engine A of the eccentric-rotor liquid-piston type, a steam turbine T, a boiler B heated by a burner J, and a superheater A<2> in which steam generated in the boiler passes, but does not mix with, exhaust gases from the engine A. The turbine exhausts to a condenser C and the condensate is pumped through an oil cooler 0 to a feed-water heater H heated by exhaust gases from the boiler, before they pass to atmosphere through a pipe E<2>. A rotary blower S supplies compressed air to the engine A. One form of rotary engine, Figs. 2, 3, has an eccentric rotor A<3> provided with curved vanes M<3> which separate the combustion chambers B<3> bounded by a liquid ring L<3>, which is impelled centrifugally around a wall G5. For two-stroke working, air is taken into the combustion chambers at the position Cb, compressed, and fuel is injected at the position Ct, the mixture expanding and impelling the rotor upwards towards the exhaust and scavenging air ports. In an alternative arrangement, the rotor has sliding vanes in place of the curved vanes M'. A deflector plate R<3> extends inwards into the working spaces, and blades M<4>, M<5>, join the deflector to the walls W', W<4>. Inlet and exhaust ports S<3>, E<3> are provided. Auxiliary liquid condensed in the bases of the boiler B and heater H, are led by pipes P<1>, P<2>, into a tank N, whence it is returned by gravity, or pumped, to the engine A through pipe P<5>. The depth of the liquid ring L<3> is maintained between ports X<2>, X<3>. For starting up the plant, a valve V<7> is opened, a stop valve V is closed and steam is raised by the burner J, exhaust gases from the boiler passing to atmosphere through a pipe E. The burner is then withdrawn and the valve V opened, the auxiliary liquid admitted to the engine, and fuel admitted to the latter. The fuel is supplied from a tank Q by a pump F, to a distributer D, distributer valve R, plate D<3>, passage P<8> to the injection valve-chest D<4>. The fuel enters the distributer D, Fig. 11, through a pipe F<1>, and passes via passages K<1>, K<3>, K<5>, and annular chambers K<2>, K<4>, to a semicircular, eccentric orifice K' which connects with inclined ducts K<8> in a plate D<3> which is attached to the rotor. By turning a handle H3, the position of the orifice K' may be varied, to vary the quantity of oil admitted to the holes K<8>. A fuel return pipe F<2> leads back to the supply tank, when the valve R closes the connection between K<7>, K<8>. The whole valve R may be rotated slightly by a handle H', to retard or advance the fuel injection. A spring-pressed fuelinlet valve in chest D' is lifted by fuel pressure to admit fuel to each combustion chamber. A priming passage is provided. Two working strokes per revolution may be secured by making the casing G<5> elliptical.
