Filed: 1973-10-09
Abstract: 1434296 Developing electrostatic latent images RICOH KK 9 Oct 1973 [13 Nov 1972] 47012/73 Heading G2H Electrostatic latent images on strip material 1 are developed by a liquid developer, applied by a slipping roller 5 with multiple helical grooves, or by combination of such a roller with a perforate plate 8. The roller 5 has grooves each related by a Formula to the speeds of the material and roller. In use the roller may be rotated at a surface speed of two to four times the speed of the strip material. In an example the roller has 110 grooves, with a lead angle of about 60 degrees, and is about 25mm in diameter.

Title: Labellers

Filed: 1970-10-02
Abstract: 1324697 Labelling machines T WADA 2 Oct 1970 [26 Nov 1969 27 Nov 1969 28 Nov 1969] 47017/70 Heading B8F  A machine for printing labels 6, separating them from a backing tape 7 and fixing the printed labels onto articles is operated by a single swing lever 1. The lever 1 is pivoted about a fixed rod 3 towards a handgrip 4 integral with a frame 2 to lower and rotate a printing block 11, connected thereto by a pivot 12 and a spring 13, across inking rollers 19, 20 and on to a a label 6 lying on a plate 14, and to move a pawl 39 idly relative to a ratchet wheel 38. A projection 15 on the block 11 engages in a slot 16 of the plate 14 to correctly position the block. The lever 1 is then released and moves under the action of a spring 5 to raise the printing block 11 and to rotate the ratchet wheel 36 thus drawing the tape 7 from a roll 9 and through the machine. As the tape 7 is carried over the edge of the plate 14 the lable 6 on the tape separates and is received by a frame 43. As the printing block 11 is raised a notch 34 thereon engages a projection 33 on a lever 29 to pivot the lever about 30 until a projection 26 on the block engages a projection 27 on the frame causing the block to rotate about the pin 12 and disengage the lever 29. A spring 32 returns the lever 29 with sufficient force to cause a bar 28 to push the label 6 from the frame 43 and apply it to an article. Ink holding rollers 19, 20 are attached to a biased lever 21 and contact the base of the printing block 11 when in its raised position as shown. Slots on the tape 7 cooperate with projections 37 on the feed wheel 36. In a further embodiment, Fig. 13, the lever 29 is in two parts 29b, 51 pivoted together and the bar 28 is separate from the lever so that it is not raised upon raising of the lever 29 but is forced through the frame 43 upon the release of the lever 29. The printing block 11 also differs in that the notch 34 and projection 26 are formed on an arm 50 pivoted to the body of the block so that rotation of the body is not necessary. Rotation of the arm 50 takes place  in the opposite direction from that of the printing block of the first embodiment, and the  lever 29 is released as the notch 34 moves to the right of projection 33. It is also envisaged to pivot the lever 1 about at one end thereof and to support the printing block 11 towards the middle of the lever; the operations preformed by the raising and the lowering of the lever 1 being interchanged.

In the embodiment of Fig. 2, the electrodes 2a and 4a, together with an electrode array for conductors 4a, are formed on the insulating layer 3 and are separated from the discharge space 7 by a dielectric film 5, e.g. of solder glass, the electrodes 2a being connected through the layer 3 to a conductor array formed on its under surface. In other embodiments, the conductor arrays for both sets of electrodes are formed in the same plane, on base-plate 1 (Fig. 5, not shown), an insulating layer portion (23) being provided between them only at each crossing point; or the conductor arrays are formed on opposite faces of the insulating layer 3, which is unperforated; or the proportion of each discharge path located in the gaseous medium may be increased by forming the electrode portions on opposite sides of U- or V-shaped continuous grooves in the base-plate 1 (Figs. 8 and 9, not shown) or on diametrically opposite sides of hemispherical depressions formed in the base-plate, one at each crossing point (Figs. 10 and 11, not shown). A numeral display panel, Figs. 15 and 16, includes 8-shaped patterns of triple conductors, the centre conductors 84 of each triple being individually connected to separate leads 91 to 98, while the two outer conductors 82a and 82b of all the triples are connected in series to a common lead 90. The device may be filled with a neon/nitrogen mixture. Methods of fabrication, involving printed circuit techniques, are described.

[Also in Division H1] An optical information storage and display device comprises a cathode-ray tube having face-plate of light conducting fibres 19, each fibre having a photochromic glass core of selected refractive index and a cladding on the core of light transmitting material of lower refractive index, the fibres being arranged side by side in a hermetically sealed bundle, and a layer 20 of phosphor (e.g. ZCaO.MgO.ZSiO 2 : 0À05 Ce). The core may become less transparent when irradiated with blue or ultra-violet light, remain unaffected by green light and become more transparent on irradiation with infra-red, red or orange light. In a digital memory system, incoming binary coded signals specifying the X-Y co-ordinates are converted to analogue voltages in converters 25, 26 and a serial binary code pulse group at 31 determines the emission or otherwise of phosphor 20 at each point. Readout bias supply 30 may effect a low intensity readout electron scanning beam (e.g. 10-<SP>6</SP> to 10-<SP>7</SP> the writing beam intensity), the light output being detected by photo-cell 32. The core may be bleached by heat or red or infra-red light from source 35 for example (e.g. 630 millimicron emission). Between the phosphor and photochronic layers, a dichroic layer (40) (Fig. 3), may be included transmitting and reflecting light of 380 and above 450 millimicron respectively. Light from probe source 43 (e.g. 550 nm.) may be reflected from the dichroic layer and projected by lenses and mirrors to a futher screen (47), and erasure may be by flood source 42 emitting light of 630mm. Overlay information (e.g. forms and maps) may be superimposed (Fig. 4, not shown).
