Title: Azo dyestuffs containing an amino-pyrazole residue which are sparingly soluble in water, and their use
IPC: C07D231/46
Filed: 1964-08-26
Abstract: The invention comprises sparingly water-soluble azo dyestuffs containing no water-solubilizing groups which dissociate acid in water of the formula <FORM:1034489/C4-C5/1> wherein A represents a phenyl radical which contains at least one nitro group in o- or p-position to the azo bond, B represents an optionally substituted phenyl or naphthyl radical and R represents a C1-C4 alkyl group. They may be obtained by coupling the diazonium compound of an aromatic amine of the formula <FORM:1034489/C4-C5/2> with a coupling component of the formula <FORM:1034489/C4-C5/3> Further substituents which may be present in the phenyl radical A are nitro, trifluoromethyl, cyano, halogen C2-C4 alkanoyl, aroyl, carboxylic acid ester, N-unsubstituted or substituted sulphonic acid amide or carbamyl or sulphamyl, or alkylsulphonyl or arylsulphonyl groups.  Substituents in the phenyl or naphthyl radical B are for example halogen, C1-C4 alkyl, C1-C4 alkoxy, acylamino, sulphonic acid aryl ester or sulphonic acid amide groups substituted on the N atom by alkyl.  The diazotization may be performed by using nitrosyl sulphuric acid.  The coupling is preferably performed in an acid to weakly acid medium. The dyestuffs are suitable for dyeing of hydrophobic, synthetic organic fibres from an aqueous dispersion, for example for dyeing of textile materials such as cellulose di- or triacetate or polymeric esters of aromatic polycarboxylic acids with polyvalent alcohols, mainly polyglycol terephthalates.  They are also suitable for dyeing synthetic polyamide fibres such as nylon. Polyester fibres are dyed with aqueous dispersions of the dyestuffs at temperatures of over 100 DEG C. under pressure, or at 100 DEG  C. in the presence of carriers or by the pad dyeing process. Dyeings on polyglycol terephthalate fibres give an orange shade.ALSO:Pyrazoles of the formula:- <FORM:1034489/C2/1> wherein B represents an optionally substituted phenyl or naphthyl and R represents a C1-C4 alkyl radical; are obtained by reacting an alkanol corresponding to R with a cyanoacetic acid hydrazide of the formula B-HN-NH-CO-CH2-CN in the presence of hydrogen chloride.  The compounds are useful as intermediates in the preparation of dyestuffs (see Division C4).

Title: A process for the preparation and concentration of free hydroxylic substances from marine oils
IPC: C07C69/52
Filed: 1965-08-17
Abstract: A process for freeing and concentrating the hydroxylic compounds from marine oils comprises alcoholysing a marine oil with a lower aliphatic alcohol containing 1-3 carbon atoms, dissolving the alcoholysis product in a nonpolar solvent, contacting the said solution with a polar solvent immiscible with the non-polar solvent and recovering the hydroxylic compounds from the polar phase.  The alcoholysis is preferably carried out in the presence of an alkaline catalyst and an excess of the alcohol. Suitable non-polar solvents include herring or dogfish liver oil and hexene, and preferred polar solvents are lower aliphatic alcohols containing up to 30% water.  It is particularly preferred to use the anhydrous form of a lower aliphatic alcohol as the alcoholysing agent and the same alcohol, containing some water, as the polar solvent, methanol being particularly useful.  Specified hydroxylic compounds include Vitamin A, selachyl, chimyl and batyl alcohols.

Abstract: 843,405. Controlling conveyers by radiation. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 28, 1957 [Nov. 28, 1956], No. 36347/56. Class 40(3) [Also in Groups XXX and XXXVI] The invention is concerned with indicating or controlling the condition of flow in a fluidized conveyer which consists of a sloping tube divided longitudinally by a porous diaphragm into two parts, in the upper of which comminuted material flows under gravity and to the lower of which air under pressure is supplied to maintain the material in a fluidized condition. In the preferred embodiment the flow passes between a pair of condenser plates, one of which may be earthed, and variations of the capacity indicate the condition of flow. The change in capacity may be indicated by a tuned circuit which comprises the test condenser and is coupled to a relay. The indicator signal may be amplified and used to control the feed. A number of such alarms may be situated at various points along the conveyer. The Specification states that the flow in such conveyers is usually of a pulsating nature and the figure shows a circuit in which each pulsation causes the detector circuit to operate switch S. This transfers the charge from a condenser 62, previously changed from the supply through rectifier x, to condenser Cl which maintains R operated. If the pulsation frequency falls relay R falls out. The Specification states that a Beta ray emitter or light source and suitable receiver may detect the passage of the material.

A clutch 11 and an associated belt-driven brake 15 interposed between an electric motor 10 and change-speed gearing 13 driving a beetslicing or other machine are electrically actuated and are provided with two control means, one of which may be automatic, additional to the control for normal machine operation. One additional control means, such as a manual actuator 25, causes alternate energization of the clutch and brake to produce a stepwise operation of the machine (for inspection, adjustment or repair). The other additional control means, such as an actuator 26, causes simultaneous weak energization of the. clutch and brake so that both slip to produce a slow rotation of the gearing 13 and thus facilitate gear changes therein. As shown, the brake coil 16 is energized through normally-closed switches 17, 19. Alternate depression and release of the " stepwise " actuator 25 causes alternate closing of the switches 22, 19 to effect alternate energization of the clutch and brake. Depression of the " slow-running " actuator 26 causes simultaneous energization of the two coils 16, 21 through respective resistors 18, 24 to cause weak engagement of both the brake and the clutch. It is stated that the alternate energization of the clutch and brake may, in a modification, be effected automatically by current pulses from a time relay or speed dependent device. Suitable clutches and brakes include those, such as magnetic-powder or eddy-current types, which are suitable for slip operation. Electromagneticallyactuated friction clutches and brakes may also be used.
