Title: Improvements in or relating to colour television cameras
Inventor: BLACKBURN WILLIAM JAMES

Filed: 1968-11-14
Abstract: 1,244,206. Television. MARCONI CO. Ltd. 6 Oct., 1969 [14 Nov., 1968], No. 54052/68. Heading H4F. In a colour television camera comprising at least two tubes arranged to receive different colour images from an objective lens via a colour separating optical system, the effects of lag due to different light intensities at the tubes are balanced by interposing a modifying lens in at least one of the light paths from the objective to the tubes to cause the images at the tubes to be of different sizes. Thus, in a three-tube camera (red, blue and green), " positive " or image size reducing lenses may be interposed between the colour separating system and the blue and red tubes, with, or without, a " negative " lens in the green path. Alternatively, a " negative " lens only may be used, in the green path. In a modification, the colour separating system is divided into two parts so that green is initially separated, and a single " positive " lens is inserted in the common (red + blue) path.

Abstract: 1447103 Isostatic moulding MANNESMANN AG 14 Dec 1973 [15 Dec 1972] 58116/73 Heading B5A In a process for the production of a moulded body composed of a plurality of discrete layers, each layer is made from a particulate material by isostatic compression in an elastic mould, each successive layer being formed in a separate pressing operation upon the previously formed layer. Particulate material may be compressed isostatically in an elastic mould, after which the pressure is released to leave a space between the formed body and the mould into which further particulate material is fed and isostatically compressed. Alternatively the formed body is removed from the mould and placed in a second elastic mould into which the further material is fed. The formed body may be hollow e.g. by using a removable mould core. The first mould may include an elastic insert which is removed after the first isostatic pressing and before the second supply of material. The surfaces of the various layers may differ in profile and may have a lubricant or an adhesive material applied to them.

A straightening machine includes staggered roller support shafts, each of which receives an exchangeable roller, the distance between the rollers being adjustable in a longitudinal direction of the machine, and a second set of straightening rollers, rollers of said second set resting on rollers mounted on the straightening roller support shafts, the latter rollers being the original rollers or being support rollers taking the place of the original straightening rollers. A straightening machine having staggered roll support shafts 1 on which working rolls are mounted is converted to a straightening machine having a larger number of working rolls by using the original working rolls, or cylindrical support rolls 8 substituted therefor, as backing rolls for new work rolls 9, 11, 15. Roll carriers 12 may be pushed on some of the shafts 1 so that a support roll 8 on a shaft 1 backs new work rolls 9 mounted on the carrier 12, a further work roll 11 and its backing roll 10 also being mounted on the carrier 12. Roll carriers 13 pushed on the other shafts 1 each carry a work roll 15 backed by a support roll 14 on the shaft 1. Alternatively roll carriers 12 may be mounted on all the shafts 1, or carriers, each with just the two rolls 9, may be mounted on each shaft 1. The rolls 10, 11 and 14, 15 are vertically adjustable.

The disc has a rotatable axle 9 which is coupled through a threaded connection 13 to a motor shaft 14 of an electric motor 2 housed in casing 1. When motor 2 is started the inertia and friction of disc 8 prevents axle 9 from following shaft 14, the difference in the number of revolutions of shaft 14 and axle 9 being taken up by the threaded connection 13 so that axle 9 is moved downwardly against the action of spring 12 until the end of the path of rotation of the threaded connection 13 is reached. When motor 2 is switched off, axle 9 is turned back and is moved upwardly by spring 12 until disc 8 closes the mouth 6. Bristles 7 are provided on the rim of the mouth.
