Title: Method of defibring incompletely defibred vegetable material
IPC: D21B1/12
Filed: 1954-10-13
Abstract: A method of defibring with selective separation of hard particles, vegetable material, e.g. cellulose, wood, plants, which has been soaked, steamed, pre-hydrolised, or incompletely broken up by any known methods, comprises subjecting the material to a beating action in a hammer mill in the presence of water or other liquid continuously flowing through the mill and discharging the defibred product and the hard particles separately from the mill. One or more rotatable hammers are preferably disposed in a p  cylindrical housing the bottom of which is formed as a perforated plate.  The material to be treated is introduced at one end of the housing and if the flow of liquid is not strong enough for feeding the material forward, it is moved forward by slightly inclining the housing or suitably shaping the hammers, and the detached fibres are flushed through the perforated plate while the hard particles are ejected at the other end of the housing.  The ejection of hard particles from the mill may be assisted by water jets directed into the housing.  The liquid in the mill is dammed back to such an extent that liquid is always present in the mill. The peripheral outer edges of the hammers may be roughened or toothed.  The various steps of pre-treatment of the vegetable material may be combined in any desired manner.

Filed: 1971-06-25
Abstract: 1403519 Colour television EMI Ltd 20 Sept 1972 [25 June 1971] 29808/71 Heading H4F Automatic registration of the video signals derived from respective rasters of the pick-up tubes of a colour television camera, e.g. registration of the red and blue pick-up tube signals with the green pick-up tube signal, is effected by detecting characteristic edge features occurring in each signal in a sampling region which occupies a corresponding position in each of the rasters, and by comparing the timing of these characteristic edge features deriving a control signal to correct any misregistration, the sampling region being moved relative to the rasters, e.g. in a random, pseudo random or systematic pattern between successive fields. The sampling region is arranged to occupy a position within a centrally disposed portion 14, Fig. 2, comprising 60% of the height and 60% of the width of the rasters, the sampling region for the horizontal registration information being a vertical strip 15 some 1À5 Ás wide and 175 lines high for a 625 line raster, and for the vertical registration information being a sample 17 derived from a horizontal strip 16 some 1À5 Ás wide and 10 lines high. As shown in Fig. 1, the red R signal, blue B signal and green GD signal (delayed for convenience only by one line period with respect to the R and B signals) are fed to outline generators 6-8 (described in detail with reference to Fig. 3, not shown) which derive outline signals R*, B* and GD* which represent only sharp transitions in hue or luminance. These signals are applied to logic circuits 10 and 11 controlled by sample gate control circuits 12 on a logic board 9 (described in detail with reference to Figs. 4-6, not shown) to produce output control signals for shifting the red and blue signals relative to the green signals so as to tend to reduce misregistration between the signals.
