Title: Cleaning photoconductors
Inventor: BEAN LLOYD FITZGERALD
IPC: G03G21/00
Filed: 1983-10-26
Abstract: An electrically conductive (64) brush is used for redistributing the residual toner images over imaging surface (10) so that the toner can be more effectively removed from the surface by the developer system C. The brush is moved in a direction perpendicular to the direction of movement (16) of the photoconductive surface and is electrically biased by means of an A.C. voltage (66) such that not only is the toner dislodged it is also picked up by the brush from one area of the photoconductive surface and dropped it on another area. By proper selection of the A.C. and D.C. voltages the conductive brush can be simultaneously used for redistribution and uniformly charging the photoreceptor surface. The perpendicular movement may be by reciprocation of a brush as shown, or by rotation of a cylindrical brush with a helical array of bristles. <IMAGE>

Title: Audio transformers for safety isolation
Inventor: LACEY PHILIP EDWARD JAMES
IPC: H01F19/02
Filed: 1985-06-06
Abstract: A transformer comprises a laminated core 10 having a figure- of-eight configuration, the central limb of which carries a rigid insulating bobbin 12 on which are concentrically would the primary and secondary windings 14 and 16. The core 10, bobbin 12 and windings 14 and 16 are designed so that, in the assembled transformer, there are spaces between the outer winding and the core 10. These spaces are filled with a semi-rigid curable insulating compound 26 in order to prevent breakdown between the winding and the core 10 of the transformer which, in use, are at different potentials. The concentric windings 14 and 16 are isolated from one another by a layer of insulating tape 30. The tape used is extremely extensible so that its longitudinal margins can be stretched to extend radially outwards and over the edges of the end flanges 20 of the bobbin 12. The tape insulation 30 thus extends around the outer winding 16 without breaks or interstices. Such transformers can withstand high voltages and can, therefore, be used for providing safety isolation, using a standard bobbin in a wide range of sizes. <IMAGE>

Title: Process for the chemical coloration of veneers
Inventor: SCHEITHAUER MARGOT
IPC: B27K5/02
Filed: 1986-03-07
Abstract: In a process for the chemical coloration of veneers, especially of deciduous timbers of low tanning substance content, the aim consists in achievement of a complete colour penetration of the veneer, retaining a positive stained image, under industrial conditions. For this purpose a tanning substance enrichment is achieved in deciduous timbers which guarantees a uniform absorption and distribution of active mordant substance in relatively short treatment times and a chemical colour tone development in the entire veneer cross-section. In accordance with the invention the veneers to be coloured are treated in an iron (II) salt staining bath in common with an auxiliary veneer with a mean tanning substance content of 2 to 7%. As auxiliary veneers there are considered those of the wood of the copper beech, the lime tree and/or the birch. The invention is applied in the improvement of veneers such as ash and poplar.
