Abstract: Anti-counterfeiting marking for documents, which marking may be disguised as an incidental or artistic feature of overall marking on the documents is adapted to be read by a complementary reading device. In one embodiment the marking may be a one, two or three-dimensional statistically fractal marking and is representative of an array of digits in which the value of each digit is represented by the fractal dimensions over a corresponding region or set of regions of the document bearing the marking. Corresponding apparatus for reading the anti-corresponding marking is also provided.

Abstract: A device for distributing a deodorising, fragrancing insecticidal or the like product is arranged to be activated by opening and closing a room door. In one embodiment, the device comprises a spring plastics bracket 10 clipped to the bottom of a door and carrying spring clips 16 supporting for rotation a hollow plastics roller 20 containing a solid deodorant, fragrancing compound or insecticide, and having apertures in its wall to allow vaporised deodorant or the like to escape. The dispersal of the deodorant, fragrance or the like is promoted every time the door is opened and closed and so the rate of use of the deodorant, fragrancer or insecticide is appropriately related to room use.

Abstract: A photographic album is proposed for a selected theme which has pre-printed pictures or views, with accompanying text, to provide the user with guidance and inspiration to take a corresponding series of photographs on the same theme. The photographs taken are then processed and substituted for the corresponding pre-printed views, either in the same album or in a reproduction of the album so that the customer then has a structured album of photographs with appropriate accompanying text.
