Such instruments are described in Specification 7322/07, the unused halves of the half-overlapping images of the objectives (see Fig. 3a) being cut out by screens placed in the plane of the images. One of the objects of the present invention is to replace the four-lens erecting eye-piece previously used by a two-lens eye-piece. The employment of screens as before is not suitable for the twolens eye-piece and they are dispensed with accordingly, longitudinal median horizontal screens in the telescope system being now employed, as shown at a, a<1>, a<2> in Fig. 3. These screens may be cf thin blackened metal or may be formed of fine black threads strung through holes in a tube and across an open frame as shown in Figs. 4 and 5. The female separating prism is made of a single piece of glass; owing to difficulties of manufacture, the female prism F, Fig. 7, is preferably combined with a male prism M, balsam being used to fill in any irregularities in the female prism. Optical data for the prisms are given. Fig. 8 shows an arrangement for grinding female prisms. The glass p is traversed to and fro under flat circular grinders a<1>, a<2>, set one behind the other and rotating about axes inclined at the angle required for the prism.

Title: Improvements in the manufacture of carbon black
IPC: C09C1/50
Filed: 1950-06-13
Abstract: <PICT:0669511/III/1> Carbon black is produced by blasting a mixture of a fluid fuel and free oxygen-containing gases into a porous bed of refractory material, burning the mixture as it passes through the bed in contact with the refractory surfaces, passing the gaseous combustion products from the surface of the bed up through a chamber as a non-turbulent stream, passing a hydrocarbon as a plurality of substantially vertical confined streams up through the bed in indirect heat-exchange therewith and flowing them into the rising stream of combustion products above the bed, whereby a carbon black suspension is formed, which is withdrawn and cooled, and from which carbon black is separated.  Air under superatmospheric pressure passes from inlet 20 into windbox 19 and is evenly distributed by perforated plate 25 before passing through burner ports 15 in burner block 14.  Fuel gas under pressure passes through pipe 27 and manifold 26 to jets 29 situated behind ports 15.  The resulting combustible mixture is ignited and burns on the surface of the refractory material in porous bed 18, and the combustion products, preferably devoid of oxygen at 2300-3500 DEG F., pass into refractory-lined furnace chamber 1.  Hydrocarbon gas, with or without steam, passes from line 30 and manifold 31 to refractory tubes 33, wherein pyrolysis is initiated by heat from the bed 18, and thence at say an equal velocity into the combustion products in chamber 1.  The effluent gases pass through throat 9 and conduit 11 to conventional cooling and collecting apparatus.  Specifications 655,799 and 669,511 are referred to.

Patent GB-698765-A (GB)
Title: Haloacetamido diols and methods for obtaining the same
Filed: 1951-06-21
Abstract: The invention comprises the N-forms of haloacetylaminodiols of the general formula <FORM:0698765/IV (b)/1> and the manufacture thereof by one- or two-step di-haloacetylation of a q -1-p-aminophenyl-2-aminopropane-1 : 3-diol.  The one-step process may consist in the simultaneous introduction of two identical haloacetyl groups by reacting the aminodiol with a haloacetic anhydride at a temperature below about 60 DEG  C. (e.g. by heating to 40-50 DEG  C. under anhydrous or aqueous conditions, in the latter case preferably in the presence of an alkaline catalyst such as an alkali metal salt of an organic acid or an alkali or alkaline-earth metal bicarbonate or carbonate).  The two-step process (which is essential when the two haloacetyl groups are different and also applicable when they are identical) is preferably effected by first haloacetylating the aromatic amino group by the action of a haloacetic anhydride or halide under aqueous conditions in the presence of at least one equivalent of a mineral acid (e.g. hydrochloric, hydrobromic or sulphuric acid), preferably at a temperature below about 35 DEG  C. neutralizing the resulting salt of q -1-p-haloacetylaminophenyl-2-amino-propane-1 : 3-diol and reacting the free base with a lower (1-4 C) alkyl ester, halide or anhydride of a haloacetic acid under anhydrous conditions (e.g. at a temperature up to about 100 DEG  C. but preferably below about 35 DEG C. in an organic solvent such as methanol, ethanol or isopropanol). Alternatively the aliphatic amino group may first be acylated by reaction with a lower alkyl ester of a haloacetic acid under anhydrous conditions and then the aromatic amino group by the action of a haloacetic anhydride under the same conditions as for the one-step process.  The products are useful as antibiotics suitable for oral administration.  Examples describe the preparation of l- and dl - q  - 1 - p - dichloracetylaminophenyl - 2 - di - chloracetylaminopropane - 1 : 3 - diol and of l - q  - 1 - p - dichloracetylaminophenyl - 2 - di - bromoacetylamino - and 1 - p - difluoroacetyl - aminophenyl - 2 - iodoacetylamino - propane - 1 : 3-diol.  q  - 1 - p - Aminophenyl - 2 - aminopropane - 1 : 3 - diols are obtainable by reduction of the corresponding p-nitro compounds; e.g. l-q -1-p-nitrophenyl - 2 - aminopropane - 1 : 3 - diol is reduced with hydrogen in methanol in the presence of palladium on charcoal.
