Title: Shadow-mask colour cathode ray tubes
IPC: H01J29/07
Filed: 1973-12-28
Abstract: 1458229 Colour television tubes RCA CORPORATION 28 Dec 1973 [29 Dec 1972] 60089/73 Heading HID In a colour cathode-ray tube with a phosphordot screen and a shadow mask, at least one side of the mask, and the inner surface of the screen, have heat reflecting and heat absorbing surface areas for transferring heat faster from the central portions of the mask than from its margins. "Doming", which arises because the mask is ordinarily heated more in the middle, is thus reduced. As shown, the tube 11 has a faceplate 15 and a funnel 13 which, in the neighbourhood of a magnetic shield 44, has a conducting coating 17. A screen 25 with a set of three-colour phosphor dots on the faceplate 15 carries a reflecting layer 31, which in turn carries, in its central part, an infra-red absorbing layer 33, (see also Fig. 3, not shown). An apertured shadow mask 35, closely spaced from screen 25, is mounted on a frame 43 which also carries shield 44, the assembly being spring-mounted on faceplate 15. Both sides of mask 35 are blackened, and an infra-red reflective layer 41 surrounding an infra-red absorbing layer 47 is deposited on the margins. (See also Fig. 2, not shown). The absorbing layers 33, 47 are about the same in shape and size. In operation, heat is radiated from the mask more in the centre and less at the margins, so that "doming" is minimized. In modifications, a reflecting layer may be deposited on the margin of the gun side of the mask 35, and if the magnetic shield is omitted, the conductive coating 17 is made of reflecting aluminium covered in central parts by an absorbing graphite layer. Other modifications of details are disclosed. Temperature changes are described and shown graphically.

Title: Drive assembly for a pivotally mounted part, such as a machine tool head
IPC: G05B19/35
Filed: 1979-11-20
Abstract: The invention is concerned with the angular positioning of a pivotally mounted part about its pivot axis. In the particular case of this part being a machine tool head a screw drive mechanism (5, 7) of the recirculating ball nut type is used for adjusting the angular position of the machine tool head by means of a servo motor 9. A control system generates (by means of a comparator) an error signal in dependence upon the difference between first and second values ( alpha c,  alpha D), representing true and desired angular displacements, respectively, of the movable part (2), so as to control the operations of the drive motor (9) in such manner as to tend to reduce the magnitude of the error signal, the first value ???c being derived as a function of the angular rotation of the motor (by a resolver 21) from a datum position. The motor has velocity feedback from a tachogenerator 20. <IMAGE>

Title: Heat pump installation
IPC: F28D7/12
Filed: 1980-02-28
Abstract: A heat pump installation for heating a building, wherein the ground is used as a heat source, as a heat exchanger for extracting heat from the ground comprising a series of heat on exchange ducts 6 radiating from a chamber 2 in the ground. Each duct 6 comprises an outer pipe 8 and an inner concentric pipe 10. The pipes 8 are connected to an inlet header 12 for the heat exchange fluid and the pipes 10, which are lagged, are connected to an outlet header 14 for the fluid. The pipes 8 are introduced into the ground by a ram borer which is much more economic than the usual technique in which a pipe network is introduced into a large excavation and the excavation is then backfilled. Also the duct can penetrate much deeper into the ground than was previously practicable and thus more heat can be extracted from a smaller area of ground. <IMAGE>
