Title: Metal surface treatment
IPC: C23G1/00
Filed: 1964-08-10
Abstract: A process for the removal of scale from iron and steel surfaces comprises applying an aqueous pickling solution having a pH below 9 and containing a hydroxy carboxylic acid salt and an amino carboxylic acid salt, continuing pickling until the iron concentration is constant, increasing the pH to at least 9 and adding an oxidizing agent to passivate the surface.

Title: Improvements relating to shaping metal foil containers
Inventor: ECKEN JOSEPH
IPC: B21D26/02
Filed: 1964-08-10
Abstract: 1,012,378. Shaping metal foil containers. SWISS ALUMINIUM Ltd. Aug. 10, 1964, No. 32472/64. Heading B6J. Apparatus for shaping metal foil containers from a web of foil 25 comprises support-plate 19 with an aperture 20 through it for the passage of a compressed fluid such as air, the plate being arranged opposite a hollow forming die 10. The die 10 is mounted on the piston-rod 11 of a fluid-operated cylinder 13 so that the die may be moved to and fro at right angles to the plate 19. A further fluid-operated cylinder 14 is mounted on the piston-rod 11 and is provided with a hollow piston-rod 16 concentrically surrounding the piston-rod 11. A cutter or stamping die 17 is carried by the piston-rod 16. In operation, the die 10 is pneumatically lowered and held against the web foil 25 with a force, which in the first instance is approximately equal to the force exerted on the forming die and foil by the compressed air. During this first stage of shaping the foil, the foil edge'is drawn into the die at the same rate as the shaping process proceeds. The final shaping occurs during a second stage when additional pneumatic force is exerted by the cylinder 13 on the die 10 to grip the foil 25 against the plate 19. The pressure in the forming space automatically increases since the air present can no longer escape between the foil and the plate 19. Finally the shaped foil container is severed completely or partly from the foil 25 when the blade 30 of the cutter 17 is lowered by the pneumatic cylinder 14, and air is exhausted from the shaped container when the valve 34 is opened to atmosphere.

IPC: H04N9/77
Filed: 1975-08-04
Abstract: 1511898 Colour television RCA CORPORATION 4 Aug 1975 [30 Aug 1974] 32495/75 Heading H4F In a colour television receiver the bandwidth of a luminance channel 18, Fig. 1, is controlled in inverse proportion to the amplitude of the colour signal R-Y, G-Y or B-Y having the greatest amplitude, thereby giving improved definition to pictures produced from signals representing detailed images at the expense of the colour content thereof. The received signal comprises a wide band luminance component having a narrow band chrominance component interleaved therein. The chrominance component is filtered out at 44 and a colour sync unit 50 derives colour phase reference signals for driving detectors 48 and 46 the outputs of which are matrixed 52 to provide the colour signals. These are applied to a control circuit 30 which drives a variable impedance 54 in the bandwidth control unit 22. Impedance 54 determines the band elimination width of filter 56 which is centred on the colour subcarrier frequency so that the bandwidth eliminated from the luminance channel varies in accordance with the amplitude of the colour signal of greatest amplitude. The circuits of controllers 30 and 22 are described with reference to Fig. 2 (not shown).
