Title: An improved automatic corrector for compensating the deviations of sighting apparatus, range finders and the like apparatus from the horizontal or from a given inclination
IPC: F41G5/14
Filed: 1919-10-29
Abstract: 149,151. Soc. d'Optique et de MÚcanique de Haute PrÚcision. Aug. 18, 1919, [Convention date]. Self-levelling apparatus. -The horizontality or fixity of inclination of apparatus, such as sighting-instruments or guns, mounted on a platform that is subject to deviations from the horizontal, is ensured by mounting such apparatus on a fixed support on the platform, through the intermediary of a pivoting support upon which is mounted a rocking support carrying the apparatus. An interposed mercury level device fixed either to the fixed support or the rocking support acts on the rocking support either directly or through mechanical or electrical driving-means to restore the apparatus to the desired inclination in the event of the deviation from the horizontal of the platform on which the apparatus is mounted. The apparatus is moved back through an angle equal to the deviation. Figs. 1 and 2 show an example in which the control movements are produced by mechanical means. The apparatus C is mounted on a rocking support B, which is carried on a pivoting support E capable of rotation on the fixed support A carried on the plat. form. A mercury tank D carried on the pivoting support E comprises two cylinders having plungers F operating an arm G<1> of the lever G pivoted, to the support E as shown. Movement of these arms causes sliding wedge-surfaces H<1>, H<2> to tilt the rocking support B and the apparatus C. Fig. 16 shows the application of the invention to sighting apparatus for guns. One of the gun trunnions carries a plate U<1> to which is jointed the rocking support B carrying a telescope or like C. The object of the apparatus is to maintain the telescope C automatically in the position which it is been given for aiming. A mercury level device D operates relays actuating the elecltro-magnet M mounted on a core N, N'. If the gun trunnions oscillate the magnets will be operated to retain the telescope in its original position.

Title: Improvements in repeating firearms
IPC: F41C7/02
Filed: 1920-10-15
Abstract: 177,119. Marks, E. C. R., (Fabrique Nationale d'Armes de Guerre Soc. Anon.). Oct. 15, 1920. Breech actions, sliding breech-block; magazines.-Relates to non-automatic guns having a safety detent which serves both to lock the trigger during loading and to lock the breechblock in closed position. The invention consists in the application of such a device to guns in which the breech-block is actuated by a slide rigid with a tubular magazine reciprocatable on the under side of the barrel. In the form shown. the slide 5, which is rigid with the rear end of the magazine (not shown) is held in its forward position by the arm 17 of a detent 4 co-pivotal with the, hammer. On firing, a shoulder 22 on the hammer depresses the arm 17 and releases the slide 5, which may then be withdrawn to open the breech and cock the hammer by retracting the magazine. During this movement a spring 19 causes the detent 4 to follow the hammer so that the upturned nose 9<a> on the extension 9 of the detent 4 takes up a position under the downturned nose 10 on the trigger 6, and prevents this from being pulled. When the slide reaches its forward position during the closing movement, a shoulder 23 thereon depresses the arm 17, which then re-engages the notch 18 and locks the slide, the nose 9<a> moving at the same time to the rear of the nose 10. A cavity in the extension 9 in rear of the part 9<a> then permits the rotation of the trigger to fire the gun. The detent may be manually released by actuating the extension 9.

Heavy metals specified are Cu, Mn, Cr, Fe, Ni and Co.  The products yield full shades on leather, silk and wool. In examples: (1) the dyestuff metanilic acid --> 8-oxyquinoline is treated with chromium formate or ferric acetate under pressure; the dyestuff aniline --> 8-oxyquinoline-5-sulphonic acid is chromed; (2) sulphanilic acid --> 5-methyl-8-oxyquinoline is chromed as in (1) or treated with copper sulphate or tetraminine cupric sulphate; (3) 1-naphthylamine - 7 - sulphonic acid --> 5 - methyl - 8 - oxyquinoline; and (4) sulphanilic acid --> 5-chlor- or 5-brom-8-oxyquinoline are chromed as above; nitrated derivatives of 8-oxyquinoline may also be used; (5) aminoazobenzenedisulphonic acid --> 8-oxyquinoline-5-sulphonic acid is chromed as in (1) or with chromium fluoride, acetate, sulphate or other chromium salt; (6) 8-oxyquinoline \sM benzidine-3 : 3<1>-disulphonic acid --> resorcinol; (7) picramic acid --> H acid --> 8-oxyquinoline; (8)--(10) p-nitraniline, o-anisidine, picramic acid, p-chlor-o-amino-phenol, 5-nitro-o-aminophenol or 4-nitro-o-aminophenol-6-sulpho acid --> 8-oxyquinoline-5-sulpho acid are chromed as above. Phenyl-amino-8-oxyquinolines and 8-oxyquinoline carboxylic acids are also specified as coupling components. Phenylamino-8-hydroxyquinolines are made by condensing 1-nitro-2-amino-4-, 5-, or 6-chlorobenzene with glycerol (Skraup) to the corresponding chloro-8-nitroquinoline, reacting with aniline to obtain the phenylamino-8-nitroquinoline, which is reduced to the phenylamino-8-aminoquinoline and the latter converted into the hydroxy compound by Sandmeyer's reaction.

Abstract: 1,131,010. Cross-linking polymers. RAYCHEM CORP. 13 June, 1967 [23 June, 1966], No. 27149/67. Heading C3P. Hydrogen-containing polymers are crosslinked by incorporating into the polymer one or more photo-active agents selected from t-butyl hypochlorite, oxalyl chloride, sulphuryl chloride, thionyl chloride, sulphuryl bromide, thionyl bromide, phosgene or carbonyl bromide, and subjecting the polymer to ultraviolet irradiation. Specified polymers are polyethylene, polypropylene, polybutene-1, copolymers of ethylene with vinyl acetate or ethyl acrylate, polyvinyl acetate and polymethyl acrylate. The agent may be incorporated in the polymer by diffusion. After irradiation some polymers are found to contain acid halide groups, and these may be further cross-linked by reaction by a difunctional compound, e.g. ethylenediamine, tetramethylenediamine, hexamethylenediamine, ethylene glycol and propylene glycol. Articles treated in accordance with the invention may be given elastic memory properties. Examples describe the irradiation of (1) polyethylene and phosgene, (2) polyethylene and oxalyl chloride, (3) polybutene-1 and oxalyl chloride or phosgene, (4) polyethylene and t-butyl hypochlorite or sulphuryl chloride, (5) copolymers of ethylene with ethyl acrylate, vinyl acetate or propylene and oxalyl chloride, (6) polyethylene and oxalyl chloride followed by further reaction with ethylenediamine, hexamethylenediamine or ethylene glycol, (7) a polyethylene bottle and oxalyl chloride and (8) a polyethylene tube and oxalyl chloride.
