Abstract: In the dyeing or printing of cellulose textile materials with a water-soluble dyestuff containing at least one dihalogeno-1 : 3 : 5-triazin-2-ylamino group in the presence of an acid-binding agent, improved fastness is obtained by after-treating with an aqueous solution of a compound containing at least one primary or secondary amino group, such as a -methylamino-acetic acid, ethylamine, diethylamine, dipropylamine, monoethanolamine, diethanolamine, dipropanolamine, aniline, 2-naphthylamine- 6-sulphonic acid, p-phenylene diamine, orthanilic acid, sulphanilic acid, ethylene diamine, 1 : 3-propylenediamine, N-(b -hydroxyethyl) ethylenediamine, triethylenetetramine, hexamethylenediamine, N-(b -aminoethyl) ethylenediamine and the sodium salt of sarcosine.  The aqueous solution of the amine may contain soap or a synthetic detergent and may be applied at an elevated temperature.  The dyeing or padding baths or printing pastes may contain the usual adjuvants, examples of which are given, and the acid-binding agent, or a compound liberating an acid-binding agent on heating, may be applied before, together with or after the dyestuff.  Dyestuffs of the azo, anthraquinone, nitro or phthalocyanine series may be employed and in this respect many British Specifications are referred to.  Examples are given. Specifications 209,723, 298,494, 467,815, 772,030, 774,925, 781,930, 785,120, 785,222, 797,946, 798,121, 805,562, 816,925, 819,585, 820,470, 826,405, 828,355, 829,042, 836,248, 837,035, 837,124, 837,985, 837,990, 838,311, 838,335, 838,336, 838,338, 838,340, 851,537, 852,120, 855,792, 863,155, 863,754 and 864,227 are referred to. p

Title: Improvements in variable speed transmission
IPC: F16H3/72
Filed: 1932-09-24
Abstract: 407,939. Hydraulic transmission of power. SMITH, N. L., 14, Anglesea Street, Bondi, New South Wales, Australia. Sept. 24, 1932, No. 26557. [Class 69 (ii).] Variable-speed gearing comprises a metal body 14 fast on a driving-shaft 29, Fig. 2, a sun spur wheel 10 mounted in a central recess in the body 14 fast on a driven shaft 23, a series of planet wheels 12 in mesh with the wheel 10 and in recesses in the body 14, a liquid containing chamber 22 rotating with the body 14, and liquid inlet and outlet ports 19, 21 for each planet positioned respectively near the outer edge of the body 14 and near the intermeshing region of the planet and sun gear, as shown in Fig. 3. The inlet valves 19 are opened and closed simultaneously with the closing and opening respectively of the outlet valves 21 to effect a controlled throttling of circulating oil and so to control the speed ratio. Oil in the chamber 22 is fed by centrifugal force to the inlet ports 19, which are closed when desired by valves 33 to allow the gearing to run free. The valves 33 are biassed to opened position by springs 35, Fig. 4. A slidable valveoperating cone 24, Fig. 2, controlled manually from a shaft 26 and lever 25 has holes through which pass bolts 36, Fig. 4, pivoted to levers 34 of the valves 33. When the cone 24 is moved away from the body 14, the bolts 36 are pulled, and the valves 33 close the ports 19. At the same time, piston valves 32 are moved to the position shown in Fig. 2, with vents 27 open to allow oil to leave the ports 21. As the cone 24 is moved towards the body 14, the bolts 36 are released, allowing the springs 35 to open the inlet ports 19. At the same time, the valves 32 are positively slid to cut the vents 27 off and close the outlet ports 21 gradually.

Abstract: Paraffin &c. waxes are coloured by mechanically incorporating into them colouring matters which are practically insoluble in the usual solvents, the mixing (for example by friction rollers) being continued until the colouring material is nearly colloidally dispersed in the plastic material, and does not appreciably settle out from a solution thereof.
Patent GB-1570641-A (GB)
Title: Object position and surface determining methods and apparatus
IPC: G01S17/32
Filed: 1977-06-28
Abstract: The position determining device (10) exhibits a mask (16) which can be displaced along an axis (T) located in the reference plane. A light source (20) can be displaced together with the mask (16). A sequence of photocells (26) with a lens (26a) contains photocells (PC1-PC7). The mask (16) contains transparent sections and opaque sections. Planes (P1, P2, P3), in which the radiation-reflecting objects (O1, O2, O3) are located extend in parallel with the said axis (T). The time required by the radiation pattern to pass over a location in the planes (P1, P2, P3) is a measure of the distances (x1, x2, x3). When light source (20) and mask (16) are displaced, the objects (O1 - O3) are successively irradiated by light, with intermediate periods without radiation. During the displacement of the pattern, the sequence of photocells (26) detects an energy reflection by the objects (O1 - O3). An output signal is generated at the rate of the pulse repetition rate and is processed in order to establish the object distance. <IMAGE>

Abstract: 263,581. Stewarts & Lloyds, Ltd., and Baltantine, J. Oct. 30, 1925. Tubes.-In making lap-welded iron and steel tubes, the strips are scarfed and skelped in one continuous operation by gripping the strip in advance of the scarfing rolls by tongs connected 'to a draw bench chain and drawing them thereby from the furnace through the rolls and skelping- die. The scarfing-rolls 12, 13 and skelping-die 11 are mounted on a draw bench 1, which may be traversed by an electric motor and gearing 7, 7<a> on rails 3 parallel with the furnace A. The strip is pushed forward so that its front end projects from the furnace by a push-out bar inserted through an opening in the rear wall. It is then drawn through the machine from the furnace by tongs 25 connected to a draw bench chain 5. The parts of the die are carried in slots 10 on a table 9 and may be separated to facilitate removal of a strip which may stick in the die, and the tongs and strip are guided in the die by a roller 28. A member 29 pivoted at 29a is used to remove scale from the die. The scarfing-rolls are carried by removable housings 14 and are provided with cylindrical portions 21, 22, bevelling portions 24 and gaps 26 through which the tongs are drawn. The upper rolls are adjustable by screws 19. The rolls may be constructed so as to scarf the edges of the strip on the same side instead of on opposite sides as shown in Fig. 3. The skelp may be subsequently reheated and welded.

Title: Manufacture of metalliferous azo-dyestuffs
IPC: C09B45/20
Filed: 1935-10-03
Abstract: Metalliferous azo-dyes are prepared by treating an azo-dye from a diazotized o-aminophenol- or an o-aminonaphthol-ether containing as nuclear substituents one or more hydroaromatic residues and an azo-component adapted after coupling to form complex salts, with an agent which yields metal, under such conditions that the ether group of the diazo component is eliminated.  The ethers used as diazo components can be made by sulphonating cyclohexylbenzene, melting the product with caustic soda, etherifying the hydroxy group, nitrating and reducing; alternatively, the foregoing oxy derivative is first nitrated, then etherified and finally reduced.  In examples: (1) diazotized 1-methoxy-2-amino-4-cyclohexylbenzene is coupled with 1-n-buty-4-oxy-2-quinolone and the dyestuff powder dissolved in pyridine is heated to boiling with cobalt hydroxide (red-brown shades): (2) the azo dye 1-methoxy-2-amino-4-cyclohexylbenzene --> 2-3-oxynaphthoyl-1-butylamide is boiled in pyridine with cobalt hydroxide (violet).
