A conveyor for articles of various thicknesses includes a continuous conveyor belt driven around spaced rollers and a stationary housing that encloses the belt. Spaced groups of brushes or bristles are secured on the outwardly facing surface of the belt such that the ends of the bristles may slide across an opposed surface of the housing. The bristles are inclined toward the direction of travel or conveyance of the belt in order to catch the edges of the conveyed article and impart a positive th...

A security document has security printing formed as a moire pattern of two superimposed sets of generally parallel lines. In each line set the line spacing varies progressively along the length of the lines so that each line set has one or more areas in which the line frequency is low and individual lines can be seen with the naked eye, and one or more further areas of high line frequency in which individual lines can only be readily distinguished by using magnification. Futhermore, the thicknes...

The present invention relates to an improved pin device which comprises a pinning means (hereinafter referred to as A means) and a fastening means (hereinafter referred to as B means). The present invention provides a fastener that does not loosen easily and slip off like an ordinary pin and can function both as a pin and a clip.

A method of, and system for, merging a portion of one document into another and providing for current viewing and on line editing. During preparation of a document, a paragraph from another document can be included in the document being prepared by referencing the other document and paragraph. The result of referencing is inclusion of the paragraph, a view of the document being prepared, and a document including the included paragraph which is dynamically editable. If the paragraph is edited, an...

This invention relates to documents, such as banknotes, which are produced and used in large numbers and which, for a given series, are identical one with another except for a unique multi-digit number upon each individual document, the number thus uniquely identifying that document within the series. According to the present invention, to render unauthorized reproduction of the document more difficult, on each document, at least two characters in the identifying number differ from each other (i...

There is described a case for valuable documents, such as notably checks, credit cards, bank notes, etc., comprised of a box with a lid and a closure which may only be opened by inputting a code number, as well as a capsule or phial filled with a pressurized liquid which can destroy or make useless said documents, in which said capsule or phial is made completely or partly from fusible material, and said capsule or phial may be opened or unplugged electrically when electric or electronic means t...

A method for making security documents using an electro photographic printer, particularly a photocopier or laser printer, includes the step of exposing the printed image to an accelerator, in liquid or vapour form. Under the influence of the accelerator, a second dye contained in the toner, used in producing the image, migrates into the document, thereby producing a second image in the paper in registration with the printed image. The process is applicable to images created on paper, security p...

The present invention relates generally to documents, e.g., such as legal tender, currency and identification documents, and apparatus for encoding documents. One claim recites: a physical document including a machine-detectable hidden signal. Presence of the hidden signal is determined by collecting visible light image data associated with the document and transforming the image data to a complementary domain to generate transform data. Presence of a telltale pattern in the transform data indic...

A lamp projecting a high-intensity optical beam of spectral radiation, with an IR-extracting (cooling) array including an IR-dissipating "black-box" arranged to receive IR and convert it to box-heat, plus an IR-diverting "hot-mirror" interposed along the beam to divert (only) the IR to this "black-box".

Systems and techniques are disclosed wherein a method of providing a security code for a document comprises applying a first magnetic feature capable of being read by a contactless magnetic reader and having a fixed magnetic signature selected from a set of magnetic signatures, and applying a second magnetic feature capable of being read by a contactless magnetic reader and characterized by its magnetic signature and its spatial location on the document. It is emphasized that this abstract is pr...
