Specified compounds are ethylene glycol monoacetate, propylene glycol acetate, ethylene glycol monomethyl ether acetate, ethylene glycol monoethyl ether acetate, diethylene glycol monoethyl ether acetate and methyl acetoacetate, and specified solvents are water, acetic acid, alcohols, glycols and glycol ethers. The solution may contain surfactants and buffers, e.g. sodium acetate, and residual compound on the substrate may be hydrolysed. The etchant may be chromic acid, and after treatment therewith the substrate may be mixed with water and washed with mild alkali before electroless and electroplating. Preferably the substrates are aged for up to 24 hours before electroless plating, particularly after treatment with a solution of an anionic or non-ionic surfactant. In examples ABS resins are pre-etched with aqueous solutions of (1) diethylene glycol monoethylether acetate and (2) ethylene glycol monoethylether acetate.

[Also in Division B7] A vehicle anti-dazzle rear-view mirror Figs. 1 and 2, comprises a mirror assembly 22 carried by a part-spherical section 16 and a hub 14 from a bracket 12 securable to the vehicle, the assembly 22 including an enclosure or chamber 21 containing an optically dense light attenuating liquid 29, a transparent glass window 26 and a plate of glass 34 within the chamber 21 and having a highly reflective surface 36, the plate 34 being movable to a position in which it is in substantial abutment with the window with only a thin layer of liquid squeezed there-between, by means of radial spring fingers 40 on an annular metal member 38 and being movable away from the window by an electromagnet 44 so that a masking layer of liquid is formed between the window and reflective surface which substantially cuts out the reflections from the surface 36 so that only weak reflections from the outer surface of the window 26 can be seen by the driver of the vehicle. The electromagnetic 44 coacts with an armature disc 45 secured to the plate 34 and is energized through wires 50. Liquid can move from one side of the plate 34 to the other via an annular gap 42. In other embodiments the plate 34 is positively indexed into substantially parallel abutting relationship with the window e.g. by thin wafer stop members secured by cementing to window or the reflector plate. In an embodiment described with reference to Fig. 9 (not shown) the plate 34 is movable by an electric solenoid away from the window and by a coil spring towards the window. According to the embodiment of Fig. 12 the liquid is retained by an elastomeric diaphragm 190 so that changes in volume due to wide differences in temperature are catered for. The central portion of the diaphragm is secured at 212 to the reflector plate and the outer periphery to the casing 186, the rear wall 192 being provided with three depression sions to receive the expansion of the diaphragm. The mirror assembly 180 in this case is universally mounted in a housing 182 on a spring-urged pin 238 and remotely controllable by three flexible cables (only 250 and 252 are shown) in known manner. The reflector plate 33 is movable away from the window by a flexible cable 224 and urged against the window by a spring 244. Other means permitting expansion of the liquid are described with reference to Figs. 14, 15 and 16 (not shown). The liquid preferably has a refractive index in the order of that of the window 26.

Abstract: 1506990 Separating aromatics and olefins from paraffins DEUTSCHE TEXACO AG 12 Nov 1976 [13 Nov 1975] 47273/76 Heading C5E Olefinically and/or aromatically unsaturated compounds are separated from a paraffin-rich hydrocarbon mixture by treating the mixture with a dehydrated macroporous cation exchange resin in the form of a metal salt (e.g. a copper or silver salt) and the loaded resin is thereafter regenerated by treatment with one or more mononuclear aromatic hydrocarbons (e.g. benzene, toluene or xylene) at 50-150‹C. to desorb the unsaturated compounds. The resin is used in examples to absorb aromatics from deoiled slack wax, hydrogenated white oil, n-paraffins produced from molecular sieve or urea dewaxing, and a white oil produced by refining an extracted spindle oil with oleum. The resin can be rinsed with isooctane at 60-65‹C. before and/or after the desorption or nitrogen can be passed through the desorbed resin to remove mononuclear aromatics prior to a subsequent adsorption stage. The mononuclear aromatics can be stripped from the purified hydrocarbon with water vapour.

Abstract: 1360086 Measuring thickness of layers ELEKTRO-PHYSIK HANS NIX & DR ING E STEINGROEVER KG 12 Oct 1971 [12 Oct 1970] 47460/71 Heading G1N In measuring the thickness D of a layer 1a on a substrate 1 by using a conductive reflector 2 and a probe coil 4, a preliminary adjustment of the probe circuit is carried out on a part of the layer 1a away from the reflector. Calibration is done using a dummy reflector comprising a metal mesh (8) between two layers of dielectric (9, 10) of different thicknesses, whereby three calibration points can be obtained, namely: infinity (no reflector) and the two points corresponding to the thicknesses of the dielectric layers (with the dummy reflector placed on top of the probe housing 3). The coil 4 is connected in an oscillatory circuit 5 and consists of one or more turns of a solid screened coaxial cable in a flat plane, the outer conductor of which is connected to a point of zero signal potential in the electric measuring circuit. The diameter of the coil is about 1¢ times the expected thickness of the layer 1a. The coil is excited at a frequency not less than 2MHz. The coils may be on a movable stand by which it may be supported a little above the surface of layer 1a or lowered thereon.

Abstract: 1413523 Automatic analysis; removing liquid from container DAMON CORP 18 Oct 1972 [22 Oct 1971] 48092/72 Heading G1B Liquid is removed from a test tube 19a by inserting a probe 42 with a bulbous end 43 so that a small annular space is formed between the closed end of the tube and the probe and passing a gas stream into the probe so that it passes through the annular space removing liquid thereby. The probe can be gradually withdrawn from the test tube so as to completely remove liquid contained therein. The process is particularly suitable for a continuous clinical analysis apparatus in which a top tray 1 is furnished with a plurality of holes for accommodating probes for delivering or removing fluid from test tubes and tray 2 containing the test tubes. Probes 5 and 6 supply samples to test tubes with probes 11 and 12 supplying reagents when tray 2 is rotated. Continuing rotation of the tray allows aspiration of the sample/reagent mixture by probes 18 and 19 to a source of measurement e.g. a colorimeter. Wash liquid is introduced by probes 22 and 23 and is removed via probes 26 and 27. Further washing then takes place using supply by probes 29 and 30 and removal by probes 39 and 40. Air is sucked up probes 41 and 42 entraining water from the sides of the tube. Finally air is blown down probes 52 and 53 while the trays are moved vertically apart and the last traces of water are blown out of the test tube. Trough 35 is for liquid overflowing from the surface of tray 2. Troughs 36, 36a contain liquid maintained at selected different temperatures.
