Patent GB-720732-A (GB)
Abstract: 720,732. Treating liquids with gases. SOC. DES USINES CHIMIQUES RHONEPOULENC. Feb. 20, 1953, [Feb. 20, 1952.] No. 4826/53. Class 55 (2). Packing for rectification columns, gas washing towers, &c., comprises elements in the form of blocks, rings, balls, &c., consisting of a core of liquid-impermeable material coated 'with a porous surface layer having pores of a mean radius greater than 0.001 mm. and preferably between 0.001 and 1.00 mm. The cores may be formed of crushed and screened sandstone, brick, or porcelain waste, preferably spherical fragments being selected slightly smaller than the elements required. Material, e.g. pumice, with non- intercommunicating pores may be used. The porous layer may be formed by applying to the cores a resistant powder by means of an organic glue which is then destroyed by heat and possibly pressure, leaving suitably sized voids between the sintered or agglomerated grains. In an example, waste sandstone fragments having a largest dimension of about 4 mm. are coated with an aqueous polyvinyl alcohol solution and covered with a porcelain powder having a mean diameter of 200 microns. The element coating is then made porous by heating the fragments to 1050‹ C.

Title: Cigarette sleeve with filter
IPC: A24C5/42
Filed: 1979-02-07
Abstract: A cigarette sleeve with filter is manufactured by passing a paper strip 1 from a roll 2 to a former 5 via an adhesive applicator 3. The former 5 bends the strip 1 to shape which is then supported on a conveyor belt 6.

Title: Optical position encoder arrangement
IPC: G02B5/32
Filed: 1979-07-14
Abstract: An optical position encoder 1 uses a number of individual tracks 51-53. The optical sensors 30-35 are positioned remotely from the encoder disc and to avoid the need for a large number of individual light paths between the encoder disc and the sensors, a single optical fibre 15 is used in which the light is frequency multiplexed. The frequency multiplexing takes the form of a number of narrow band colours 21-26 which are selectively reflected from the disc preferably by holographic reflectors 2, further reflectors 17 being used to separate the transmitted light into its constituent wavelengths. A process for obtaining the holographic reflectors is described. The concave reflector of Fig. 4 is obtained by illuminating 64 a metal ball 61 in contact with sensitised gelatine film 62 on a glass plate 63. <IMAGE>
