In examples, (1) and (2) the acid is condensed with 2-amino-3-methoxy- or ethoxydiphenyleneoxide in presence of chlorbenzene and phosphorus trichloride; 6- or 7-methyland 7 - chloro - 2 - amino - 3 - methoxydiphenyleneoxides and 2 - amino - 3 : 7 - dimethoxydiphenyleneoxide are also specified.  They have a high affinity for cotton in alkaline solution. Specification 472,170 is referred to.  Azo dyes insoluble in water are made in substance, on the fibre or on a substratum adapted for the production of lakes by coupling a diazo compound with one of the above-mentioned arylides the components being free from solubilizing groups, such as SO3H or COOH.  In examples (3) cotton is impregnated with a solution of 2-(2<1> : 3<1>-hydroxynaphthoylamino)-3-methoxydiphenyleneoxide, alcohol, caustic soda, formaldehyde, glue and turkey red oil and developed with diazotized 2-amino-4 : 4<1>-dichlorodiphenyl ether (very clear yellowish red), (4) the dyestuff of (3) is produced in substance.

Title: Improvements relating to apparatus for locating an eyeball and determining the position of its nodal point
IPC: A61B3/024
Filed: 1958-03-24
Abstract: 852,704. Sight-testing apparatus. OMOTO, K. March 24, 1958 [March 23, 1957 (2); Aug. 16, 1957 (3); Sept. 20, 1957 (2)], No. 9390/58. Class 97(1) Sight testing apparatus includes means for determining the. position of an eyeball, such means comprising a truncated cone, placed in front of one eye, and means for adjusting the patient's head relatively to said cone, until the inner and outer ends of the cone are seen as a single circle. Thus, when the eye is in this position the distance of the nodal point of the eye, from the inner end of the cone, can be determined if the length of the cone and the radii of its two ends are known. This truncated cone may, as shown in Fig. 3, form the bore of a bush. 3 carrying part-spherical disc 4 and the auxiliary arc 5 of a perimeter, the base 1 of which carries a vertically and horizontally adjustable chin-rest 13 and a forehead-rest 17, which is pivoted at 19 to the tube 11 supporting the chin-rest, and is inclinable by screw 20. A campimeter for studying the condition of the fundus, and having a graduated plate, may also use the truncated cone. (Fig. 6 not shown). For determining the near point of each eye, the apparatus of Figs. 8, 9 comprises two truncated cones 114, slidable under the control of a screw on a frame 105 bearing graduated scales 103, along which test objects 121 are movable by a cord and pulley arrangement, between the cones and a device 104. This device 104 comprises a vertically and horizontally adjustable chin-rest 148, and a forehead-rest 163, associated with adjustable glass plates 167, one being provided for each eye. In use, the glass plate covering one eye is covered, and the chin and forehead rests adjusted until the other eye sees the inner and outer ends of the truncated cone 114 as one circle. Thereafter, the target 121, associated with the eye under examination, is moved to its nearest visible position, and the scale 103 is read, the scale being graduated so that the distance from the nodal point of the eye (i.e. the imaginary apex of the associated cone 114) to the test object will be indicated by the pointer 129. For determining the near point of convergence, the instrument is set up as before, but in this case both glass plates 167 are simultaneously uncovered, and both eyes are employed in the test, so as to sight on a single test object, slidable along the median plane of the apparatus, the scale plates being graduated so as to represent the sum of the distance of the test object from the nodal point of the eye and the distance between the nodal point and the point of rotation of the eye. (Fig. 10 not shown). In Fig. 12 is shown an apparatus for measuring the depth perception, the apparatus being a modification of the apparatus shown in Figs. 8, 9, in that three rods 121a, 121 b, and 121c are slidably mounted on scales 124, 125, and in use are moved thereon until they appear to be in line.

Abstract: Dihydrostreptomycin is stabilized in aqueous solution by the addition of a buffering agent, e.g. citrate, phosphate or acetate and one or more substances selected from a salt of sulphurous acid, a salt of hydrosulphurous acid and an aldehyde addition product thereof as a stabilizing agent.  Preferably the pH is adjusted to pH 5.0 to 8.0. Specified stabilizers are sodium bisulphite, sodium formaldehyde sulphoxylate, potassium metabisulphite and sodium hydrosulphite.

In Fig. 2 tubes 20 convey the primary fluid (e.g. sodium) through the vaporizing chambers I-V of the unit 11, and tubes 20<SP>1</SP> convey the secondary fluid (e.g. water being converted into steam) through the condensing chambers I<SP>1</SP>-V<SP>1</SP> of the unit 12. In this case the heat transfer fluid may comprise diphenyls or triphenyls vaporizing at an elevated temperature of say 500‹ C. In one alternative arrangement (Figs. 4-6), the condensing chambers (26) each comprise an annular chamber in which the vaporized heat transfer fluid is condensed by the secondary fluid flowing through open-ended tubes (37, Fig. 4) of narrow elongate cross-section extending through said chamber; the condensate being revaporized in a cylindrical chamber (25) containing a primary fluid coil (28). A plurality of the condensing chambers (26) are stacked to form a condensing unit (Fig. 6).

An alternative form of condenser for the heat transfer fluid (Figs. 9, 10) similarly consists of separate chambers in which the heat transfer fluid vapour is condensed by the secondary fluid flowing through series-connected tube groups in said chambers, each tube group comprising tubes extending between headers.

Title: Process for preparing esters and polyesters of dicarboxylic acids and glycols
IPC: C08L67/00
Filed: 1959-03-20
Abstract: In the manufacture of polyesters by the polycondensation of a bis-glycol ester of a dicarboxylic acid (or a low molecular weight polyester thereof), there is used as a catalyst a uranium compound such as uranium oxide, uranyl nitrate, uranyl sulphate, uranium tetrachloride, uranium tetrafluoride, uranyl fluoride, uranyl acetate or sodium manganese uranyl acetate.  The bis-glycol ester is preferably made by an ester interchange method and the uranium compound may also be used as the catalyst for this reaction if, desired together with another ester interchange catalyst, e.g. zinc acetate, manganous acetate, or a mixture of manganous acetate with sodium methoxide or zinc acetate.  The uranium compound may react with the glycol during the ester-interchange reaction to form the glycollate which acts as the effective catalyst. Specified dicarboxylic acids are phthalic, isophthalic, terephthalic, naphthalic, sebacic, adipic or azelaic acids or mixtures of isophthalic and terephthalic acids and in the ester interchange reaction they may be used in the form of their dialkyl or diphenyl esters.  Specified glycols are ethylene glycol, the propylene glycols, hexamethylene glycol, diethylene glycol and 2,2-bis - [4 - (hexahydroxy ethoxy)phenyl] - propane.  The last mentioned glycol may be made to undergo ester interchange with bis-(betahydroxy ethyl)terephthalate.  The examples describe the manufacture of polyesters by reacting ethylene glycol with dimethyl terephthalate or a mixture thereof with dimethyl isophthalate.ALSO:In the manufacture of bis-glycol esters of dicarboxylic acids by an ester-interchange reaction, there is used as a catalyst a uranium compound, for example uranium oxide, uranyl nitrate, uranyl sulphate, uranium tetrachloride, uranium tetrafluoride, uranyl fluoride, uranyl acetate or sodium manganese uranyl acetate.
