Patent GB-668474-A (GB)
Title: New dyestuffs and process for dyeing leather therewith
Filed: 1949-06-01
Abstract: Dyes for leather comprise metal complexes of nitroso-azo compounds R-N = N-R1(OH)2 NO, where R is a radical of the benzene or naphthalene series carrying at least one sulphonic acid group and R1 is a benzene nucleus to which the hydroxyl groups are attached in the meta position to each other and the nitroso group ortho to a hydroxyl group.  The metal complexes are obtained by treating the parent aryl-azo-resorcinol with nitrous acid, adding a metal salt in aqueous medium and isolating by acidification or salting out.  The products may exist in the tautomeric quinoneoxime form.  They dye leather in brown shades of good fastness, especially to light.  Suitable metals are copper, manganese, nickel, cobalt, iron and chromium.  When the dyestuffs contain further metallizable groups, e.g. o : o1-dihydroxy-azo groups, these also may take part in complex formation; by varying the amount of metal salt or by using different metal salts successively, variations of shade may thus be obtained. The aryl radicals R and R1 may be substituted, e.g. with nitro, alkyl, chloro, carboxy, amino, arylamino or alkoxy groups, or by further arylazo, hydroxy or nitroso groups. Suitable diazo components are metanilic acid, 2-aminophenol-6-sulphonic acid and its 4-nitro and 4-chloro derivatives, 3 - amino - 5 - sulphosalicyclic acid, 4- nitro-41 - aminodiphenylamine - 2 - sulphonic acid, o - toluidine - 5 - sulphonic acid, 2 - aminophenyl-4-sulphonic acid and its 6-nitro and 6 - chloro derivatives, p - anisidine - 2 - sulphonic acid, 1 - naphthylamine - 4 -, 5 -, 6-and 7-sulphonic acids, 2-naphthylamine-6- and 7-sulphonic acids, 1-amino-8-naphthol-3 : 6-disulphonic acid, 1-amino-2-naphthol-4-sulphonic acid and 2 - methoxy - 1 - naphthylamine - 6-sulphonic acid.  Suitable coupling components are resorcinol and phloroglucinol, the latter being capable of coupling with two mols. of diazo component (e.g. from naphthionic acid) and 1 mol. of nitrosating agent or vice versa.  Examples show the preparation of the metal complexes and the dyeing of leather therewith.

Title: Field modulated gyromagnetic resonance spectrometer
Inventor: NELSON FORREST ARTHUR
IPC: G01R33/46
Filed: 1967-03-31
Abstract: 1,117,300. Gyromagnetic resonance spectrometers. VARIAN ASSOCIATES. March 31, 1967 [April 11, 1966], No.14926/67. Heading G1N. In a gyromagnetic resonance spectrometer wherein the sample is disposed in a D.C. magnetic field crossed by an R.F. magnetic field of frequency f o  and the D.C. magnetic field is modulated at an audio frequency fm to excite frequency modulated gyromagnetic resonance of carrier frequency f c =f o +f m  or f o -f m  in the sample, the signal-tonoise ratio is improved by eliminating substantially all the lower or upper second sideband components respectively from the detected resonance signal before heterodyning this signal with a transmitter reference signal of frequency f o . With a field modulation index of 0À25, the resonance signal in the second sideband component has often only 0À5% of the amplitude of the carrier component, but has essentially the same noise content : hence, by filtering out the second sideband component, the signal-to-noise ratio may be increased by a factor #2 since the noise bandwidth of the second sideband is eliminated. Figs. 2 and 5 show two different embodiments of the invention. In Fig. 2, filter 7 may be either a band-pass filter centered on f c  or a band-reject filter tuned to the unwanted second f m  sideband, which may be the upper or lower second sideband according as f c =f o -f m  or f o +f m  respectively. In addition to the features shown in Figs. 2 and 5, a local oscillator and mixers may be provided to produce an intermediate frequency, thereby facilitating the design of the filter, Fig. 3 (not shown). The local oscillator may be connected to multipliers to provide two intermediate frequencies, Fig. 4 (not shown), which is useful for spectrometers operating at 250 Mc/s.

Powder is shaken on to the support 3 and inhaled through the aperture 8. The vessel comprises two members of cylindrical or other shape, the open ends of which are clamped, beaded, or screwed, &c. together ; and the support 3 is constituted by the.tongue formed when the aperture 8 is cut out. A cap 5 which can be turned so that apertures formed therein are brought into or out of register with the apertures 4, 8 is provided with or without reference marks or abutments to indicate when the apertures are in register. The Specification as open to inspection under Sect. 91 states that the cap 5 may slide on the vessel, and the support 3 may be constituted by a " dosing compartment " comprising one or more members secured to the upper part of the vessel, either inside or outside. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to testing machines operated by pressure liquid
IPC: G01N3/36
Filed: 1924-06-20
Abstract: 232,817. Amsler, A. May 17, 1924, [Convention date]. Testing physical qualities of materials.-A fatigue testing machine comprises at least one cylinder filled with liquid in which a piston is adapted to reciprocate, the. cylinder being in unrestricted connection with the pressure cylinder of the testing machine so that the specimen is subjected to repeated stresses. Reciprocating motion is given to the piston 2 in the cylinder 1 by a crank and link mechanism 4, 5 from a shaft 3. The cylinder 1 communicates freely with the pressure cylinder 8 of the machine 4 by means of a pipe 7. A blow-off valve 9 adjustably loaded by a spring 10 limits the maximum pressure in the cylinder 8. An auxiliary pump 11 continually forces liquid into the cylinder 8 to replace leakage, and to supply the additional quantity required when the test piece undergoes permanent deformation. In a second construction, two cylinders are used in free communication with each other and with the pressure cylinder of the testing machine. One cylinder may be turned about the crank-shaft 3 so as to produce a phase-displacement between the two pistons and thus vary their tottal output. This feature may also be attained by keeping the cylinders stationary and varying the angular displacement of the cranks. In a second modification, a differential gear is placed between the two cranks, and by turning the casing carrying the planet wheels about the axis of the shaft 3 by a worm gear the relative angular displacement of the cranks may be adjusted.
