Abstract: 737,190. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 17, 1952 [Dec. 20, 1951], No. 32000/52. Addition to 719,997. Class 98 (1). In apparatus for medical X-ray examination in which a support for rotary movement of a patient is secured to a fixed support providing longitudinal movement as described in the parent Specification the source of radiation and the image reproducer are supported at opposite sides of the support for the patient by means permitting them to be commonly movable about the patient's support in at least one horizontal plane and in such a manner that the axis of the cone of rays always passes through the same point of the image screen and through a fixed point in space. As shown in Fig. 2, the patient's bed 5 is rotatable about an axis 4 and mounted on a hollow shaft 2 journalled on a base 1 so as to be movable in two directions at right angles, as described in the parent Specification. The base 1 has an arcuate extension 6 on which a carriage 8 (Fig. 4) travels by means of wheels (not shown) engaging a slot 7 and the edge of extension 6. The X-ray tube and a fluorescent screen (which may be the screen of an electronic image intensifier) are carried on pillars 9, 10 on the carriage 8. The movement of the carriage is centred on a point M, at the centre of the axis 4 when the bed is in its central position, and the central ray passes through point M and the centre of the screen in all positions of the carriage. The carriage movement is restricted to such an extent that the central ray always passes through the shaft 2. The X-ray tube and screen (or image intensifier) may be mounted to move vertically, the central ray still passing through the point M and the centre of the screen, and to this end are carried on shafts 28, 31 journalled in brackets on sleeves 18, 23 slidable on pillars 9, 10 and connected to counterweights 22, 27 by chains, 19, 24 passing over pulleys 20, 21 and 25, 26.

Patent GB-2008497-A (GB)
Title: Inking apparatus
IPC: B41F31/06
Filed: 1978-12-12
Abstract: The invention relates to a printing machine and in particular an inking assembly therefor, the assembly having an ink-containing trough 21 with a pick- up roller 22 associated therewith, and a transfer roller 23 for receiving ink from the pick-up roller. The pick-up roller 22 is mounted for limited movement during use to and from the surface of the transfer roller preferably by mounting a central shaft 22A of the pick-up roller at opposite ends on ramp members 25. The forces arising from peripheral contact between the pick-up roller and the transfer roller tend to move the pick-up roller up the ramp members while the force of gravity tends to restore the pick-up roller to its lowermost position such that peripheral contact between the rollers is periodically broken and re- made during use. Application of the ink to the transfer roller is thus effected in a series of discrete pressing movements to assist in the production of a uniform form of ink on the surface of the transfer roller. Also a scraper member 29 engages with the surface of the transfer roller above the trough such that any excess ink removed from the surface of the transfer roller falls by gravity back into the trough. <IMAGE>
