Patent FR-2573182-A1 (FR)
Title: Condensate-heating boiler
IPC: F24H8/00
Filed: 1985-07-26
Abstract: The condensate-heating boiler comprises a housing in which a number of flues from the combustion chamber lead via a continuous downward spiral to a condensate collector chamber below and pass through the housing bottom. The flues (1) are wound in spirals of different diameters and are mounted concentrically in the housing (2). Between them are partitions (5) forming passages (4) for upwards flow and open at the top. These have return-flow unions (7) and the upper ends (8) of the flues emerging from the spirals (3) are connected to the bottom (9) of the combustion chamber (11). The latter is mounted above the spirals and below the inlet union (10) and trasversely in the housing.

Title: Frame scanning digital display system
Inventor: WALL WILLIAM ALLAN
IPC: G09G5/06
Filed: 1987-09-21
Abstract: A frame scanning graphic display system in which all the points can be addressed according to two operating modes. In the first mode, data are extracted from a revision memory M0 to M3, serialised, modified and applied to a display device at a first frequency. In the second mode, the data are extracted from the revision memory, serialised and partially modified at the said first frequency and are then further modified and transferred to the display device at an even sub-harmonic, for example a half, of the first frequency. The additional modification comprises the chaining of successive groups of display data bits. Consequently, when the frame scanning device operates at a constant scanning speed, the first mode provides high definition for the image elements but a relatively low colour definition display and the second mode provides a display with an even sub-multiple, for example half, of the definition of the image elements but with a considerably higher colour definition.
