Title: Beam-diverging multi-aperture diffraction plate
Inventor: DICICCO DARRELL
IPC: G21K1/06
Filed: 1990-05-02
Abstract: A membrane 14 increases the divergence of a beam of electromagnetic radiation by means of diffraction via a multiplicity of apertures 16 each of which is comparable in size to the wavelength of the electromagnetic radiation whose divergence is being altered. Its function is similar to that of a ground glass diffuser in visible light, except that the increased divergence is caused by diffraction rather than refraction. It is of particular use, though not limited to, regions of the electromagnetic spectrum where refraction optics are difficult or costly to fabricate, such as the well known soft x-ray regime from 0.5 to 50 nm. In one embodiment the membrane 14 is opaque and has a multiplicity of small apertures 16. These apertures 16 are chosen to be of the appropriate size with respect to the wavelength of the light being used so that the incident beam of collimated radiation 10 is diffracted into a diffuse cone of radiation 12. The required aperture 16 size can be related to the wavelength of the light being used and the semi-angle of the cone of diffraction required by the well known diffraction formulae. Alternatively the membrane may be transparent and be provided with a multiplicity of appropriately sized opaque particles or regions having a different phase charge characteristic. <IMAGE>

Patent GB-2249051-A (GB)
Title: Production of artwork
Inventor: POINTON DAVID WELLINGS
IPC: B44C1/17
Filed: 1990-10-22
Abstract: A legend is applied to artwork after preliminary assembly of the legend from individual dry transfer indicia symbols and the like on an intermediate carrier from which the indicia may be cleanly peeled. Clean peel is effected by adhering to the indicia surfaces remote from the intermediate carrier an adhesive web. In accordance with the invention, the adhesive web bears a heat activated adhesive coating. By choice of brittle thermoplastic resins for the heat activated adhesive, the adhesive web may be used either to peel the indicia away from the intermediate carrier and subsequently transfer them to the desired final receptor surface, or to put a layer of heat activated adhesive selectively on the surfaces of the indicia enabling those surfaces to be reliably coloured using a hot blocking foil.

Title: Waterheating system
Inventor: GRIFFITHS RICHARD MARTYN
IPC: F24D10/00
Filed: 1991-11-29
Abstract: A group waterheating system for a block of flats comprises one or more central boilers and pipework 4, 5 which conveys communal hot water or steam to the primary side of each of a plurality of plate-to-plate type heat exchangers 7, 7', one such heat exchanger being located on a boundary wall of each flat. Hot water generated in the secondary side of each heat exchanger 7, 7' is piped into its associated flat by pipework 9 and is used directly or indirectly therein for central heating and/or domestic hot water purposes. Because the communal hot water or steam pipework is located substantially entirely outside the flats, problems related to safety and to responsibility for the communal pipelines are avoided. Apportionment of each flat's central heating/hot water running costs is also made easier. <IMAGE>

Title: Immobilising vehicle steering.
Inventor: LIVESEY STANLEY
IPC: B60R25/021
Filed: 1992-04-10
Abstract: A steering column shaft 22 has the normal ignition steering lock situated at the keyway 20. Between the steering lock and the steering wheel 11 weaker shear points 13, 14 are incorporated which will protect the steering lock if excess torque is put on the steering wheel and will render the steering mechanism immobile. Shear point 13 comprises two cross-drilled holes through the steering column shaft. Shear point 14 comprises threaded holes which accept shearable screws to attach the steering wheel boss 12 to the shaft spigot 16. If excess torque is applied in an attempt to break the steering lock, the screws at point 14 will fail. If a thief replaces these screws with high tensile screws, the column shaft will shear at holes 13 when excess torque is applied. <IMAGE>

Title: Transferring  xerographic images to artwork.
Inventor: MCKIE PETER
IPC: G03G13/16
Filed: 1992-10-23
Abstract: Toner images formed on sheets (which may be of transparent or translucent material) may be transferred to artwork by covering the images with adhesive in order to stick the toner image to the artwork more strongly than it adheres to the backing sheet, and then peeling the backing sheet away. The toner image has adhesive applied to it by selective transfer of a low-tack pressure-sensitive adhesive from a layer of such adhesive on an adhesive substrate. Transfer is effected by bringing the toner image into intimate contact with the layer of adhesive under the action of heat and pressure and then lifting away the substrate. This leaves the backing sheet with the adhesive toner image which sheet can thereafter be used in the manner of a dry transfer sheet to transfer the toner image to artwork. The toner image may be covered, prior to the application of adhesive by the selective application of a further layer of coloured material, such as from a blocking foil. Transfers (or decalomania) made by such a method are described. <IMAGE>
