[Class 40 (iii).] A number of Kerr-cell elements are arranged to form a bank or screen in a plane which is optically conjugate with the receiver screen or transmitter object. In one arrangement, two sets of conductors 13, 14 are arranged at rightangles to one another. The are respectively embedded in glass plates 10, 11 between which is a space filled with nitrobenzol or the like. The conductors 13 may be connected to plates 23 and the conductors 14 to plates 24, the plates serving as extended electrodes ; or strips of metal may be bent into zig-zags to form the plates 24, Fig. 3 (not shown), while other strips are cut out to form the plates 23. The light employed may be polarized and analysed by means of obliquely arranged reflectors 17, 19, Fig. 4 (not shown). The light may be circularly polarized before passing through the Kerr cell and reconverted into plane-polarized light afterwards, two quarter-wave plates or Fresnel rhombs being provided for this purpose (22, 32, Fig. 4, not shown). An image of the Kerr cell may be projected on a screen, or viewed in the analysing reflector ; or the cell may be viewed directly through a teinte sensible mica plate and a Nicol prism. Instead of the two-dimensional screen, a single row of cells may be used in combination with a rotating mirror or a moving film. The duration of the live period of each cell may be increased by shunting it with a condenser in parallel with a resistance. The cell elements may be arranged in parallel straight lines as shown or in concentric circles. Each may comprise two plates as shown on a number of plates.

Abstract: 1,071,888. Printing apparatus; addressing machines. SCRIPTOMATIC S.A. Sept. 25, 1964 [Sept. 26, 1963], No. 39117/64. Headings B6C and B6D. In an addressing machine in which a solvent is applied to a workpiece which is then pressed in contact with a master card, and movement of the workpiece past a sensing device actuates the solvent application and the master card feed mechanism, means is provided for varying the time lag between the sensing operation and the consequent actuation. Movement of a workpiece by feed rollers 18, 30 past a sensing switch S causes, after a delay caused by an electronic time delay circuit, the disengagement of a stop to permit one revolution of a friction clutch to cause shaft 88 to rotate. The latter operates a cam mechanism (Fig. 7) to depress the solvent applying roller 38 into contact with the workpiece, the roller being fed via wick 44 from the solvent container 40. Rotation of shaft 88 also operates a crank mechanism (Fig. 5) to operate a feed finger to eject the lowest master card in the magazine 53 for confrontation with the workpiece between the pressure rollers 46, 22. The variability of time lag may be effected by variation of resistance in a time constant circuit in the above-mentioned electronic circuit or by physically moving the sensing device S lengthwise along the first path or by changing roller speed.

Abstract: 1478207 Optical fibre transmission WESTERN ELECTRIC CO Inc 13 Sept 1974 [18 Sept 1973] 39967/74 Heading G1A [Also in Division H1] An arrangement for compensating for mode or wavelength dispersion in optical fibres includes a depleted semi-conductor body portion forming a delay line terminated by a detector characterized by charge carrier gain, the line being so located in relation to the fibre exit port that the components of the emerging radiation most delayed in the fibre are incident on the line at locations less remote from the detector than the less delayed components. Typically, Fig. 1, the body portion is a section of epitaxial #-type layer on a P+ silicon substrate located between n+ inclusions, the biasing arrangements being such as to deplete the layer and provide a drift field driving photo-electrons towards inclusion 25 which is protected by guard region 25.5 and forms with the layer a detector junction biased to give a non self-sustaining avalanche on receiving drifting photo-electrons. The optical arrangement includes lenses 12, 14 and a diffraction grating 13, though a prism could be used instead. In an alternative arrangement with reversed conductivity types the region 25 forms the floating base zone of a transistor having an emitter zone within region 25 and a collector constituted by the layer and substrate. With suitable dimensioning full compensation of fibre material dispersion can be achieved. Mode dispersion can be compensated using the annular variant of the Fig. 1 structure shown in Fig. 3 with the fibre axis aligned with central n+ zone 23 so that the most delayed modes impinge on the depleted region closest to annular detector zone 55.
