Title: Acyloxy vat dyestuffs and process for their manufacture
IPC: C09B6/00
Filed: 1961-08-04
Abstract: The invention comprises vat dyes which contain an external hydroxyl group, that is a hydroxyl group which is bound through a bridge to a ring forming part of the nucleus of a vattable ring system, esterified by an organic acyl residue derived from a carboxylic or sulphonic acid and which acyl residue contains at least one sulphonic acid group. The dyes are made by acylation of a vat dye containing at least one suitable hydroxyl group with an appropriate acylating agent, halides being specified. Vat dyes specified are those of the anthraquinone, perylene tetracarboxylic acid diimide, naphthalene tetracarboxylic acid diimide, pyrene-quinone, indigo, thio indigo or cobalt phthalocyanine series. Examples illustrate dyes of the isodibenzanthrone, dibenzanthrone, acedianthrone, dianthraquinonylamino triazine, di(benzoylamino)-anthraquinone and perylene tetra-carboxylic acid diarylimide series. Acyl residues specified are derived from mono- or disulpho benzoic acids, benzene disulphonic acids, sulphofuroic acid, sulpho-thiophene carboxylic acid and sulpho-chloracetic acid. Examples are given. The dyes are generally water-soluble and may be vatted in alkaline hydrosulphite or even in glucose or sodium sulphide solutions at room temperature. They vat-dye and print natural and regenerated cellulose by the usual methods, the acyloxy groups being hydrolysed.

Title: Electrical contact members having corrosion-resistant electrically-conductive coatings with one coating having a greater length than the other
IPC: H01R13/11
Filed: 1964-12-03
Abstract: To avoid wearing of a coating 41, 51 (Fig. 2), provided on contact springs 4 and 5 in an edge connector, a second coating 9, 10 provided on the printed circuit board is such that when the circuit board is mated with the connector the length of the surface of the coatings 41, 51 swept by the surface of the coatings 9, 10 is greater than the length of the surface of the coatings 9, 10 swept by the surface of the first coatings 41, 51. In the embodiment described, this is done by applying the second coating to the ends of studs 8 which are soldered to the printed circuit board 3. Thus, as the printed board is inserted only the top portion of the studs 8 come into contact with the first coatings 41, 51. The top of the studs may be grooved (Fig. 4, not shown), to provide guide channels for the contacts 4, 5 and the ribs 7 which support the printed circuit board 3 whilst in the connector may be provided with projections to ensure correct alignment. The coatings may be of gold, rhodium, palladium or tin.

Title: Weight transfer tractor hitch
IPC: A01B61/02
Filed: 1965-10-20
Abstract: A hitch for use with a tractor having pressure control when drawing a semimounted or trailed implement or trailer comprises a U-shaped frame 18 pivoted on the draft links 10 and, at its upper end, connected to the lift arms 16 by a U-shaped frame 30 and connected to the attached implement by a chain 33.

Title: Process for the manufacture of a rutile pigment by reacting titanium tetrachloride with oxygen or gases containing oxygen
IPC: C01G23/07
Filed: 1966-12-09
Abstract: Rutile TiO 2 pigment is produced by reacting gaseous TiCl 4 with 0 2 in a reaction chamber, and cooling the reaction products with cold inert gas in an immediately adjacent mixing chamber, the cold gas being introduced into the end remote from the reaction chamber and in countercurrent to the reaction products. Initial contact with the cold gas, which may enter at room temperature, and by then is at 800- 1250 C., prevents further particle growth but allows rutilization to continue. The cold gas may be air, N 2 , C0 2 , C1 2 , or cooled product gases freed from TiO 2 . It may be introduced at one or several points, e.g. at 400 m.3 per 500 kg. TiCI 4 . Preferably, the reactants are introduced downwards, the cold gas upwards, and the gas mixture withdrawn either through a pipe concentric within the cold gas inlet pipe (Fig. 4) or sideways from the middle of the mixing chamber (Figs. 1-3), coarse TiO 2 being removed from the bottom. The cold gas inlet may have a conical distributer (Fig. 2) or guide vanes which impart spiral flow (Fig. 3). The mixing chamber may be cylindrical or conical, and of circular or square cross-section. In examples, TiCI 4 containing AlCl 3 at 350 C., O 2 at 250 C., and CO (auxiliary) at room temperature are used, and the products withdrawn at 730 C. The TiO 2 produced contains less than 1 % anatase.

Title: Process for treating a powdered fat-containing milk product
IPC: A23C9/16
Filed: 1971-09-23
Abstract: The reconstitution properties in cold water are improved of a powdered fat-containing milk product, especially whole milk powder, by applying a coating of lecithin, possibly dissolved in a fat. The quantity of lecithin and the quantity as well as the melting characteristic of the possible fat which is applied, are proportioned in dependence of the quantity and the melting characteristic of free surface fat present on the milk product prior to the treatment, as well as in dependence of the specific surface of the milk product. Hereby the quantity of lecithin and possible added fat plus the free surface fat present prior to the treatment is kept within specified limits, and the ratio between lecithin and that part of the free surface fat present before the treatment which is liquid at ambient temperature plus that part of the possibly applied fat which is liquid at ambient temperature is also kept within specified limits, and further a specified minimum thickness is obtained of the liquid fraction present on the surface of the product after the treatment. The treated product has excellent reconstitution properties in cold water.

Title: Textile finishing
IPC: D06M11/13
Filed: 1971-10-22
Abstract: The flame-resist properties of natural and synthetic polyamide fibres, especially wool and wool blends, are improved by depositing in the fibres an organic chelate or fluoride complex of titanium, preferably to the extent of 0.2 - 2.5% calculated as titanium dioxide. The complexes may be dissolved as such in an aqueous medium and applied by spraying, padding or by exhaustion from a bath. Alternatively the complexes may be formed in situ in the aqueous medium by adding a complexing agent to a water-soluble titanium compound or on the fibre, as by treating with a fluoride solution fibres already treated with a titanium compound, which may itself be a chelate complex. Where the titanium complex is applied from a bath a dye can be applied to the fibres from the same bath, either simultaneously or as a separate step.

Title: Valve device for draining liquid contaminant collected from compressed gas
IPC: F16T1/34
Filed: 1972-09-28
Abstract: A drain valve device is provided adapted for draining liquid contaminant such as oil and/or water, collected from compressed air or other gas. The valve is closable by the gas pressure and loaded to open when the pressure sufficiently falls to permit the discharge of collected contaminant. The device incorporates a captive contaminant outlet tube separate from the valve and manually displaceable to operate and open the valve against the gas pressure. The tube may project from the valve casing sufficiently to enable it to be gripped and displaced to operate the valve without the risk of contaminant or compressed gas coming into contact with the operator's hand. An external drain pipe may be coupled to the tube and displaced from a remote position to operate the valve. The tube can be snapped into a captive position in relation to the valve casing while being axially displaceable relatively to the casing for operating the valve. The casing may comprise a skirt which is slotted and elastically expansible and provided with projections and a collar on the outlet tube can be forced past the projections to captivate the tube.
