Title: Gas discharge display devices
IPC: G09G3/28
Filed: 1972-12-28
Abstract: 1412250 Gas discharge display panels FUJITSU Ltd 28 Dec 1972 [28 Dec 1971] 59925/72 Heading H1D Luminescent material 47 provided in one panel 40 of a stack of panels 20, 30 and 40 is excited to differing degrees of brightness in dependence on the number of panels operated simultaneously. Each panel has a cross-bar addressing system of electrodes 25, 26; 35, 36; 45, 46 either covered with insulating material 24, 34 and 44 or exposed to the gas filling which may be a mixture of He and either Xe or Kr. Plates 22 and 32 separating the panels are of U.V.- or I.R. -absorbing material depending on whether or not the excitation of the material 47 is primarily by U.V. or I.R. Alternatively the dielectric layers 24, 34 and 44 may be made of U.V.- absorbing material, or separate layers of such material may be provided. In an alternative arrangement (Fig. 3, not shown) the discharge spaces 23, 33 and 43 are each divided into a plurality of separate cells and a spot of luminescent material is provided in each cell of one panel. This arrangement reduces cross-talk which may be further reduced by including optical fibres in the plates 22 and 32. In a further alternative embodiment (Fig. 4, not shown) providing a multi-colour display, strips of red-, green- and blue-emitting phosphors are arranged in repeated order parallel to the electrodes 45 of panel 40 so that a picturedisplay element is defined by three electrodes 45 and one electrode 46. The discharge spaces 23, 33 and 43 may be in communication through holes in the plates 22 and 32. Alternatively the panels may be individually sealed with a different gas composition in each panel. A fourth panel may be added to the stack. The X and Y electrodes of each panel may be insulated from each other and located on the same wall surface.

Patent GB-2003937-A (GB)
Title: Dyeing or printing fibrous materials
IPC: D06P3/82
Filed: 1978-07-05
Abstract: It is known that dyeings and prints, especially those obtained with reactive, disperse or direct dyestuffs on synthetic or cellulosic materials, often suffer from reduction effects, which generally occur during steam fixation. An oxidizing agent may be added to the dyeing liquor or printing paste, but it has been found that sometimes presently used oxidizing agents are either too mild to overcome the reduction effects or so strong that they damage the dyestuffs. The present invention provides a process for dyeing or printing a fibrous material, wherein the material is dyed, preferably pad-dyed, with a dyeing liquor, or printed with a printing paste, containing a dyestuff and an oxidant, which oxidant has an oxidation potential in a 0.05% by weight aqueous solution of from +200 to +300 mV. The oxidant is preferably present in an amount of from 2 to 50 grams per litre of dyeing liquor or kilogram of printing paste.

Patent GB-2055723-A (GB)
Title: Transport apparatus
IPC: B61B13/08
Filed: 1980-08-01
Abstract: A drive unit 1 and a slave unit are movable in unison along a predetermined path. The slave unit is disposed beneath the drive unit to move along a tunnel 4, 5 with workstations located at intervals along the tunnel. The drive unit carries electromagnets which when energised levitate the slave unit within the tunnel, control means being provided to maintain the slave unit at a desired position relative to the drive unit. The roof 5 of the tunnel is formed from a magnetically transparent material, such as glass. The slave unit is thereby physically isolated from the drive unit. As a result the drive unit is shielded from any hostile environment within the tunnel and resulting, for example, from the transport of radioactive or toxic materials by the slave units. This simplifies repair and maintenance operations on the drive unit. <IMAGE>
