Title: Improvements relating to signal relaying apparatus
Inventor: CUTTS FREDERICK WILLIAM
IPC: H04B7/155
Filed: 1959-03-07
Abstract: 943,837. Radio signalling. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 24, 1960 [March 7, 1959], No. 7966/59. Heading H4L. Television or other amplitude modulated R.F. signals are transmitted to a receiver sited near a satellite transmitting station and at the receiver, after frequency reduction, the I.F. acting as a subcarrier frequency modulates a UHF carrier which is by a directional radio link transmitted to the satellite station. The latter has a filter 6 suppressing one sideband of the received carrier whose output being then amplitude as well as frequency modulated, is detected by an amplitude detector 7 to derive the amplitude modulated I.F. subcarrier. The latter may then be transposed up in frequency and transmitted from the satellite transmitter. The output of the single sideband filter 6 may be reduced in frequency by a local oscillator 13 and the I.F. amplified by tubes having in their anode circuits a pair of circuits in series respectively tuned to the I.F. and to the sideband frequency spaced from the I.F. by the amplitude modulated subcarrier frequency. The I.F. may also be applied to a filter 14 energizing an amplitude detector 15 and frequency discriminator 16 and respectively producing A.G.C. and A.F.C. control voltages. Several subcarriers may be used to produce multiplexing. Further, the sideband filter 6 may be located at the receiver sited near the satellite station so that only one sideband of the FM link is used.

Title: Means for preventing formation of rust in turbines when at rest
IPC: F01D25/00
Filed: 1921-03-15
Abstract: 160,171. Ljungstr÷m, F. March 16, 1920, [Convention date]. Blades etc.; heating parts.-To prevent the formation of rust in turbines when at rest, a heating element is placed within the turbine or its steam conduits so that upon each stoppage of the turbine the air or gas circulating round the inner members thereof is heated. Preferably, the heating element consists of a steam coil connected with the boiler, and the steam may flow through it either continuously or only when the turbine is at rest. Thus, a valve 22, Fig. 2, is adapted to shut off steam from the turbine inlet 24 and direct it through a pipe 23 to a heating element 8 in the turbine outlet 5. The heating element may be mounted entirely or in part in the condenser.

Title: Improved method of producing kinematographic projections in natural colours
IPC: G03B41/04
Filed: 1922-03-24
Abstract: 196,778. Spõth, W. March 24, 1922. Colour kinematography; optical systems; projection screens.-Polarized light is utilized for the projection of kinematograph pictures in natural colours; beams of the required colour being obtained by the polarization of ordinary light, successive pictures being projected with complementary colours. Light from a source a passes through a condenser b, c and a negative lens d, to render the rays parallel, and then through a polarizing prism e to collect lenses g, h, from which it passes to the analyzer i and thence through the lens k, the film m and the projection lens l. A doubly retracting plate f is situated between the polarizer and analyzer, giving a coloured beam, depending upon the thickness of the plate. The corresponding complementary colour is obtained by rotating the plate f through an angle of 90‹. By the intermittent rotation of this plate f through a right-angle, successive pictures are projected in complementary colours. More than two colours may be produced by making the plate of plates of different thicknesses. The polarizer may consist of a Duboscq calcite prism or polarization may be effected by reflexion. In one example the projection screen serves as the analyzer by being provided with a metallic surface or coated with a crystalline substance. The different thicknesses of doubly-refracting material may also be placed on successive pictures for changing the colours instead of using a plate f.

Title: Improvements in the refining of crude aromatic hydrocarbons containing at least two condensed ring systems
IPC: C07C7/177
Filed: 1943-05-31
Abstract: Crude aromatic hydrocarbons containing at least two condensed ring systems, particularly naphthalene, which may comprise up to about 5-10 per cent of olefines or diolefinic bodies, are refined by treatment with aluminium chloride or other polymerizing agent of the same type, for example, ferric chloride or boron fluoride, in an amount of 5-10 per cent by weight of the olefinic impurities, at a temperature of 80-250 DEG  C.  The raffinate is removed from the polymer by distillation which is effected in vacuo or with steam unless the aluminium chloride is removed first.  In examples:  (1) crude naphthalene obtained by oil cracking is treated with 0.1 per cent of aluminium chloride at 100 DEG  C. for 2-3 mins., the product then being distilled in vacuo; (2) a naphthalene from coke oven tar is similarly treated with 0.25 per cent of the chloride; (3) naphthalene from oil cracking is treated similarly at 200 DEG  C. for 10 mins. and distilled in vacuo; (4) naphthalene from coke oven tar is treated as in (3), the product being cooled to 90 DEG  C. and washed with 10 per cent caustic soda before steam distilling.  U.S.A. Specification 2,071,521 is referred to.

Abstract: 512,951. Electrolytic etching. JACKSON, L. MELLERSH-.(Norris, Inc., E. O. March 22, 1938, No. 8777. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 14, 1939.] [Class 41] [Also in Group XX] Pitted or perforated metal surfaces for use in photo-mechanical printing processes, or as stencils, screens or sieves or as matrices for the electrodeposition of screens are prepared . by coating a metal surface with light-sensitive material, photographically printing a series of bands thereon by means of a line screen, and printing a second series of bands crossing the first series. The material of the bands is rendered impervious to an etching agent and the surface is then etched. Suitable material for the sensitive coating is gelatin, photo-engraver's glue, albumen, or gum, sensitized with ammonium or potassium bichromate. A second coating may be applied before the second set of bands is printed. The metal plate may be of copper and the etching agent may be iron perchloride. Electrolytic etching may be used. Where the second coating is of different material from the first, etching may be effected with both sets of bands present, then one set removed and further etching effected, resulting in a sheet as in Fig. 15 in which the surface 20 has ribs 32, 33 at different levels. The intermediate pits 31 may be filled with material resistant to electrolytic deposition and the sheet used for the deposition of a screen. Suitable resistant material is asphaltum, wax, or the material known under the Registered Trade Mark "Bakelite." The line screens used for the two printings may be different or a single screen in two successive positions may be used..

Abstract: 1394681 Resin-fibre structure IMPERIAL CHEMICAL INDUSTRIES LTD 28 March 1972 [6 April 1971] 8818/71 Heading D1R [Also in Divisions C7 and H1] In an electrode for supporting pastes used in primary or secondary cells, or for use in electrochemical processes, having at least a surface portion which consists of electrically conductive fibrous material in a polymer matrix, conductive fibres project from its surface. The bulk portion of the electrode may be of the same material as the surface portion or may be any shapable conductive or non- conductive material. The fibrous material may be metal; or metal-coated glass, silica, or asbestos. The polymer may be a thermoplastic, rubber, or a cured composition. In one embodiment the fibre/polymer composition is moulded and the surface of the body selectively abraded by, for example, sandblasting to expose the fibres. Three other embodiments use a felted mat or tangled mass of fibre. In one, lead-coated glass fibres are matted with a small quantity of PVC and the mat immersed in methylmethacrylate; the impregnated mat is removed and polymerised at 56C for 1 hour and 90C for 4 hours. The body may be formed against a ribbed surface. In a variant, the surface of the mat is scuffed before immersion in the methacrylate. In the third example, a mat of lead-coated glass fibres is laid on a flat surface at the bottom of a mould and a polyester-forming composition is poured in so that it rises to just short of the top surface of the mat, the composiion then being allowed to solidify. These electrodes may support a lead/lead-oxide pastes for lead-acid secondary cells.
