Patent GB-914772-A (GB)
Title: Improvements relating to the lubrication of equipment which is exposed to ionising radiation
IPC: C10M101/02
Filed: 1960-01-29
Abstract: Equipment that is exposed to ionizing radiation is lubricated with an oil that is derived from an extract obtained from a crude petroleum vacuum distillate or a deasphalted vacuum residue by means of a solvent, for example, furfural, which preferentially extracts aromatic hydrocarbons from mixtures with non-aromatic hydrocarbons. The extract may be at least partially dewaxed, for example by conventional dewaxing techniques such as methyl ethyl ketone/toluene, ethyl chloride/methyl chloride, or propane dewaxing.  The extract or dewaxed extract may further have its aromatic content reduced, for example by chromatographic methods employing alumina or silica gel. The oil may be thickened to a grease with an inorganic or other non-soap thickener, for example of the silica or bentonite type, or sodium terephthalate or an aryl substituted urea.

Title: Improvements in or relating to flexible couplings for transmitting rotary motion
IPC: F16D3/68
Filed: 1937-02-05
Abstract: 484,834. Universal joints. SILENTBLOC, Ltd., and TRIER, V. A. Feb. 5, 1937, No. 3469. [Class 80 (ii)] In a flexible coupling of the kind comprising axial rubber bushings F, mounted in a carrier D and connected alternately to shaft-flanges A, A, such connection is effected by the use of. intermediate plates B, B secured to the shaftflanges and the bushings. Thus, to dismantle the coupling it is necessary to remove only short bolts C connecting the flanges and intermediate plates, whereupon the carrier and intermediate plates can be removed laterally as a unit. The risk of the long bolts G of the bushings fouling adjacent apparatus when dismantling known couplings without such intermediate plates is thereby avoided. The rubber bushings F adhere by compression to the carrier D and to internal sleeves E, to which the bolts G are secured by nuts H, which also space the bushings from the plates B. The latter have large holes B<3>, accommodating the heads of the bolts G and have tapped holes receiving the bolts C, G. The plates B may be centred on the flanges either by a spigot connection, or in the case of circular flanges and plates, by flanged discs K, secured by the bolts C. Rectangular flanges and plates may be used. The carrier D is in two parts riveted together.

Title: Improvements relating to aerials
IPC: H01Q19/30
Filed: 1954-02-05
Abstract: 761,674. Aerials. ANTIFERENCE, Ltd., and BEST, N. M. Feb. 1, 1955 [Feb. 5, 1954], No. 3500/54. Class 40(7) An aerial consists of two conductive elements, one of which is gapped at its centre for the connection of a feeder, which are electrically connected together by means of two cross-members arranged intermediate the ends of the elements and on either side of the gap. The elements are approximately parallel for, at any rate, the distance between the cross-members and the impedance of the aerial at the feeder connection point can be adjusted by alteration of the positioning of the cross members. Such an aerial is shown in Fig. 1 as part of a Yagi aray. The two elements 16 and 14a and b are here of the same length and diameter and are spaced apart a distance of a few times the element diameter. The gap between the half elements 14a and 14b occurs inside the supporting junction box 15 to which the feeder is led. The gapped element is arranged in this box above the element support boom 12 while the element 16 passes through and is supported by the box in a position below the boom. Cross-members 17a and 17b are adjustably positioned between the elements and in use are clamped equidistantly from the boom at positions giving the required aerial impedance. The ends of the elements extending beyond the cross-members may be parallel as shown or may be arranged to diverge from one another in order to increase the band-width. Fig. 3 shows the invention applied to an X type array. In this embodiment 21a and b is the gapped element to which a feeder is connected inside the junction box 20 and 23 is the continuous element which is bent at its centre so that its two halves lie parallel to the two halves of the other element. Element 23 is mechanically supported by the cross-members 24a and 24b. Metal to metal contact between the cross-members and the elements may be avoided by inserting a thin insulating layer between them to form a capacity having a negligable impedance at the frequency of use.

Patent GB-878986-A (GB)
Title: Aminoplast resins and coating compositions based thereon
IPC: C08G12/32
Filed: 1958-02-04
Abstract: Aminoplasts are formed by reacting at least 3 mols of n-butyl alcohol with 1 mol of a condensate formed from 1,5-2,5 mols of formaldehyde with 1 mol of N-tert.-octylmelamine.  The products are soluble in organic solvents, and compatible with other resins.  They form coating compositions in admixture with alkyd resins.  The reaction of formaldehyde and octylmelamine may be performed in presence of an alcohol and if desired an aromatic hydrocarbon initially at a pH of 6-8 and then at a pH of 4-5. The condensate is then butylated, diluted, e.g. with butanol, toluene or xylene, and if desired mixed with an alkyd resin and/or a catalyst.  Suitable catalysts are p-toluenesulphonic, sulphuric, hydrochloric, phosphoric, oxalic or a halogenacetic acid, or substances such as butyl acid phthalate or triethylamine mono salt of maleic acid.  Pigments, extenders, fillers or delustrants may be included in the compositions, e.g. titanium dioxide, copper phthalocyanine, ultramarine, lead chromate, barium sulphate, zinc chromate or carbon black.  Suitable alkyds for use with the aminoplasts may be formed from phthalic, succinic, adipic, or sebacic acid; ethylene, diethylene, propylene, dipropylene or trimethylene glycol; glycerol, trimethylolethane, trimethylolpropane, pentaerythritol, sorbitol, mannitol, dulcitol, or inositol.  They may be modified with fatty acids from oils many of which are mentioned, or with small amounts of maleic acid.  In the Examples 1, 2, 3, octylmelamine was condensed with formaldehyde in butanol and xylene and the product further condensed with butanol.  The resin solution was thinned with xylene.  In Example 4, a thermosetting coating composition was made up from the aminoplast of Example 1, a cotton acid oil modified glyptal resin, carbon black, Prussian blue, TiO2, chrome green, and xylol.  In Example 5 a coating composition is prepared from an alkyd from glycerol, phthalic anhydride and coconut fatty acids, the butylated aminoplast of Example 1, titanium dioxide and xylol.  Nitrocellulose may be incorporated into the compositions.ALSO:N-tert-octyl melamine (M.P. 160-162 DEG C.) is prepared by refluxing equimolar amounts of tert-octylcyanamide and dicyandiamide in n-butanol containing KOH.  The reacted mixture is cooled and the product precipitated with methanol, filtered, washed, dried and crystallised from ethylene dichloride.

Title: Improvements in the dyeing of textile materials
IPC: D06P1/22
Filed: 1944-02-29
Abstract: Cellulosic textiles, both fabricated and raw stock, comprising natural or artificial fibres, e.g. cotton, linen, and regenerated cellulose, dyed with vat or sulphur colours, are afforded an oxidising, or an after-treatment in standard plant adding aqueous hydrogen peroxide or aqueous sodium perborate and maintaining the pH substantially within the approximate range 8 to 11 by adding an inorganic salt of a strong base and a weak acid other than sodium bicarbonate.  Advantageously, sodium tetraborate is used, and generally, buffer salts of acids having an ionization constant not exceeding about 1 X 10 6 are preferable.  The concentration of hydrogen peroxide and the amount of buffer employed in the oxidation bath depend generally upon the amount of dyestuff and alkali carried into the bath by the textile, but the peroxide or perborate may advantageously be used in amounts equivalent to about 0.25-1 per cent, based on the weight of textile treated.  The bath temperature may be varied within the approximate range 120 DEG  F. to 160 DEG F.; for the oxidation of vat dyes an optimum of about 140 DEG  F. and for after-treating sulphur colours an optimum of about 130 DEG  F. is specified.  In examples: (1) twill is dyed with a composition of Vat olive R, Vat khaki 2G and Vat olive green BN, prior to a fourfold treatment in an oxidation bath comprising aqueous 100-volume hydrogen peroxide and sodium tetraborate at approximately 140 DEG  F. and pH approximately 9 to 11; (2) twill is dyed in a bath containing Indigo yellow GD, sodium hydrosulphite and caustic soda, prior to treating in an oxidising bath prepared from hydrogen peroxide or sodium perborate, buffered with sodium tetraborate to pH 9 to 10 or pH 9 to 9.5.
