Abstract: 1,250,473. Electric couplings. E.M.S. ELECTRICAL PRODUCTS Ltd. 16 Jan., 1969 [19 Jan., 1968], No. 2908/68. Heading H2E. An electrical distribution system comprises two conductors 17, Fig. 2 of U-shaped crosssection, in an extruded aluminium casing 10, from which they are insulated by U-section sheaths 14, and a plug assembly, Fig. 3, having two contact blades 44, 45 and two support arms 55, 56, the plug assembly being inserted into the slot in the casing 10, between housings 13a, 13b thereof, and then turned through 90 degrees to bring the conductor blades 44, 45 into engagement with the conductors 17 and the support arms 55, 56 into engagement with complementary casing recesses 55a, 56a, the thicknesses of these arms and recesses being such that engagement in one relative position only is possible. The casing may be of a different conductive or insulating material. The insulating sheaths 14 have beads 15 which co-act with inwardly turned lips 16 on the housings 13a, 13b to hold them in position. Lips 19 on the sheath serve to retain the conductors 17. A strap 20 may be used to mechanically connect adjacent sections of casing, electrical connection being by means of a copper blade 23 in an insulating block 22. Bridging sections (17a, 14a, Fig. 1, not shown) may be used to bridge gaps between the casings. Plug assemblies may be inserted anywhere along the casing, and the spaces between them may be closed by insulating strips (not shown). In a preferred embodiment, the plug has a cover 26 and an insulating platform in two parts 25a, 25b, Fig. 5, which are formed integral with terminal blocks 31, 32 respectively, having terminals 31a, 32a therein. Block 31 also carries an earth terminal 33. A clip 131 supports the outlet cable. The contact blades 44, 45 terminate in foot portions 44a, 45a, blade 44 thereby being directly connected to one line of the outlet cable, and blade 45 to the other via a fuse 36 and switch 39 in series. The switch 39 may be omitted (Fig. 8, not shown). Earthing connection is by a spring leaf contact 46, Fig. 3, so arranged that it makes contact with the casing 10 before the blades 44, 45 make contact with the conductors 17. On removal of the plug, the earthing connection is not broken until the supply connection has been broken. The plug assembly also includes interfitting post portions 42, 43, which support the contact blades 44, 45. The plug is held in its operative position by an insulating spring-biased detent head 59 engaging the slot. A push-button 64 is provided to release head 59. In another embodiment (Fig. 9, not shown) the casing has flanges (100), by which it may be secured to a ceiling or the like. An insulating appliance support having no contacts (Figs. 10 to 13, not shown) may be plugged into either embodiment of the housing by means of support arms (102, 103) which function in the same way as arms 55, 56. A ring portion (107) or a like suitable attachment may be used to suspend an appliance from the support.

In the production of a multi-colour print by a subtractive colour process in which cyan, magenta and yellow component electrostatic latent images are successively formed and developed on a photoconductive insulative layer 1 having a conductive backing layer 2, the use of developers containing impure cyan and magenta colouring agents is compensated for by developing the magenta and yellow images while spaced a small distance from respective cyan and magenta mirror images on a second photo-conductive insulating layer 4 having a conductive backing layer 5, the required and mirror images having charges of the same sign and a bias voltage being applied between the two conductive layers. Charge or discharge image areas may be developed.

Abstract: 1,258,129. Titanium dioxide pigments. E.I. DU PONT DE NEMOURS & CO. 2 April, 1969 [5 April, 1968], No. 17194/69. Heading C1N. TiO 2  pigment is coated, by (a) adding an aqueous silicate solution to an acid agitated aqueous slurry of TiO 2  pigment so that 3-10% of silica (calc. as SiO 2 , based on wt. of TiO 2 ) is precipitated, the pH on completion of the addition being not more than 7; and then (b) adding a source of alumina to the agitated slurry maintained at pH 6-8 so that 1-10% of alumina is precipitated (calc. as Al 2 O 3 , based on wt. of TiO 2 ). The TiO 2  pigment may be anatase or nitrile, particle size 0À15-0À3 micron. Silica precipitation may be effected either by neutralizing, by addition of silicate solution, an aqueous TiO 2  slurry initially acidified by an amount of acid in excess of, or stoichiometrically equivalent to the "alkali" content of the silicate, or by simultaneously adding silicate and acid to the slurry at constant pH level, e.g. 1. Specified acids are H 2 SO 4 , HCl, H 3 PO 4  and hydrolysable compounds such as TiOSO 4  and TiCl 4 . Alumina precipitation may be carried out by simultaneously mixing, with the slurry, acid and alkaline solutions, one of which contains an A1 salt. Specified pairs of reagents are NaOH and Al 2 (SO 4 ) 3 , NaAlO 2  and H 2 SO 4 , NaAlO 2  and alum. The process is. applicable to TiO 2  derived from gas phase oxidation or hydrolysis of TiCl 4 , or hydrolysis of a seeded H 2 SO 4  solution of a titaniferous ore. The TiO 2  may have been calcined in the presence of, or treated with other oxides. In one example, the product also contains hydrated TiO 2 , derived from the TiCl 4  used to acidify the initial TiO 2  slurry.

Abstract: 1,258,482. Selective signalling. R. MAUDUECH. 11 Sept., 1969 [11 Sept., 1968], No. 44843/69. Heading G4H. In a non-linear analogue to digital converter, an input signal is attenuated by successive powers of 2 and the result when less than a preset amount is digitized linearly. As described an input signal is sampled 10, inverted 20 if its sign is negative, and applied to a 6-rung 302, 304 ... 312, ladder attenuator 30. Each rung of the ladder is controlled by an associated comparator 313, 315 ... 323, so arranged that when an input signal is applied at terminals 30 to the ladder, when the comparators eventually reach a stable state the output of the ladder at a terminal 36 is less in magnitude than 16. The attenuation necessary to achieve this result is indicated by the markings on leads B, C ... G. The output signal 36 from the ladder is then applied to a linear coder of which the first stage includes a comparator 325 and an operational amplifier 50. This encoder produces four output bits A, X, Y, and Z. The amplifying factor indicating bits B, C, D, E, F, G together with the first bit A from the linear coder are themselves recoded digitally to provide three bits T 1 , T 2 , T 3 , which together with a sign bit 21 and the remaining three bits X, Y, Z from the linear coder, constitute the final output digital signal. In a modification (Fig. 4, not shown) the sixstage ladder is divided into two halves, each of three stages, which are coupled by a fixed gain amplifier so that the resulting signal that is passed to the linear coder can be of larger amplitude. An example of a conventional transistor switch (Fig. 2, not shown) and of a transistor polarity detector (Fig. 3, not shown) is  described.

The mandrel is axially aligned with the basket and is rotated on a shaft 27. The plating bath 23 comprises nickel sulphamate, nickel chloride, boric acid, sodium lauryl sulphate and the sodium salt of saccharin in specified proportions. The frame member 29 is movable horizontally and vertically so that the mandrel can be removed from'the tank.

As shown, elements 14 have hooks 32 on one side and radial flanges 40 on the other. During assembly, hooks 32 of one disc are snapped into recesses 38 in the next disc and remain therein to prevent relative rotation of the discs and to build up a support of any desired length. End element 16 is secured to one end disc 14 by its hooks 44, and hooks 32 on the other end disc are pushed through and snap into looking positions in apertures 54 in an end fitting 18. The filter tube (112) is pushed over the assembly, and finally end element 12 is screwed into fitting 18 by its threaded boss (20), thereby preferentially crushing the ends of tube (112) into sealing engagement with annular shoulders (27) and 50 on elements 12 and 16. Parts 12, 14, 16, 18 may be made of any of a wide range of plastics, particularly polypropylene, optionally reinforced with glass fibres. The filter tube (112) is self-supporting and may be of randomly oriented glass fibres of 0.1 to 5 microns diameter bonded with 3 to 45% epoxy resin. Alternative tubes may be woven or non-woven or wound filbres of carbon, glass, rayon, cellulose, nylon, olefinic resins, asbestos, metal and polyesters.
