Title: Improvements in Ophthalmometers.
Inventor: INSKEEP CHARLES CHAMBERS
Filed: 1899-08-04
Granted: 1899-09-16
Abstract: 15,990. Inskeep, C. C., and Chambers, J. E. Aug. 4. Sight-testing apparatus.-The apparatus is for determining corneal astigmatism. The cornea is brought exactly into the focus of a telescope d, mounted to rotate in a collar on a standard g, and the reflection upon it of two "mires" or test devices w, w is examined by the operator. In the telescope is a double prism h which can be adjusted by the rack o and pinion p so as to bring the separated reflected "mires," Fig. 11, into the position shown in Fig. 12, when such adjustment is not rendered impossible by other irregularities. The scale on the milled head y then indicates the degree of astigmatism. The test may then be repeated in other meridians by turning the telescope round, the "mires" and their blackened concave carrier u moving with it. Preferably the test devices are either themselves luminous or are translucent devices, illuminated from behind, say, by electric lamps v, v The angle through which the telescope is turned is read by pointers on a scale n marked on the collar. The instrument can be turned in azimuth in the tube g, which at its lower end forms a nut engaging a screw on the standard t for raising the telescope. This screw is formed with a vertical slot in its thread, to receive a spline on a surrounding fixed sleeve so that the screw cannot rotate. The whole of these parts can be moved horizontally on the lower part of the stand by a screw.

Patent GB-190015467-A (GB)
Title: Improvements in Methods and Apparatus for Making and Collecting Ozone.
Inventor: STRONG HUGO ATHENAIOS
Filed: 1900-08-30
Granted: 1900-11-24
Abstract: 15,467. Strong, H A. Aug. 30. Ozone is made by air or oxygen flowing down. wards through two oppositely-electrified surfaces, the ozone formed being heavier than either the air or the oxygen, falling downwards by gravity, and drawing fresh air or oxygen into the apparatus at the top. The form of apparatus shown in vertical section is designed for producing ozone, and leading it into a vessel containing some liquid to be ozonized under agitation. An annular series of ozonizers A is arranged on the insulating-cover H of a vessel B containing the liquid to be treated and provided with a draw-off cock I. Each ozonizer consists of two conducting cup-shaped surfaces 1, 2, connected to opposite poles of some source of electricity, and separated by a dielectric vessel. The inner conductor is corrugated so as to leave spaces between it and the glass or like vessel. Within the inner electrode any refrigerant may be placed. Air or oxygen flows down through these spaces, and the heavier ozone which forms flows out through the outlets 4 to the vessel beneath. The liquid is agitated by a piston J, having conical holes 13, and vertically reciprocated by a rod 12 and any suitable gearing. In a laboratory form, the apparatus may be simply a glass funnel having a similarly shaped conducting-surface within and without, the inner one being separated from the funnel by insulating-blocks. The funnel leads to a collecting test-tube below. In other forms, the dielectric body and the coatings may be arranged as open cylinders ; while, if the current employed is of comparatively low tension, the intermediate dielectric vessel may be omitted. In a form for ozonizing a liquid without agitation, the cover of the vessel holding the liquid supports the ozonizer such as A, and also a charging-funnel for liquid leading nearly to the bottom, while a draw-off tap is arranged near the top of the vessel, so that the surface liquid exposed to the action of the ozone may be withdrawn at intervals, and fresh liquid introduced near the bottom.

Patent GB-190200573-A (GB)
Title: Improvements relating to Oxidizing Aromatic Amines to Obtain Amidohydroxylated Derivatives.
Filed: 1902-01-08
Granted: 1902-06-25
Abstract: 573. Vidal Dyes Syndicate, [Vidal, H. R.]. Jan. 8. Amidophenols and amidonaphthols are produced from aromatic amines in which the para position with respect to the amido group is free, by the reaction of oxidizing-agents, such as biohromates, chlorates, perchlorates, persulphates, or the like, or their acids, upon a mixture of the sulphate of the amine and concentrated sulphuric acid. An example is given in which potassium bichromate is gradually stirred into a mixture of aniline sulphate and sulphuric acid. The temperature rises spontaneously, and, on cooling, p-amidophenol sulphate crystallizes out. o- and m-Toluidine and alpha-naphthylamine may be similarly acted upon. An electrolytic method of procedure may also be adopted. The amine sulphate and sulphuric acid are placed in a stone, lead, or other vessel containing the positive electrode, and sulphuric acid is placed in a number of porous vessels containing the negative electrodes and arranged within the other vessel. Platinum electrodes are employed. The mixture is subsequently decanted off and, on standing, the amidophenol produced crystallizes out and the mother liquor is used again. Aailine may be produced in the apparatus by placing nitrobenzene in the negative compartments. The sulphuric acid in the above process limits the oxidation of the aniline to n-amidophenol. If a sulphuric-acid solution of aniline, previously oxidized and containing excess of oxidizing-agent, is progressively treated with water, p-amidooxydiphenylamine is first produced by condensation of p-amidophenol with aniline, and then this is converted into aniline-black.
