Abstract
1500592 Fingerprinting HER MAJESTY'S TREASURY SOLICITOR 1 July 1976 [1 July 1975] 27769/75 Heading B6C A fingerprint on a surface is developed by bringing an electrode adjacent the surface, establishing an electrical potential between the surface and the electrode, and introducing a powder between the electrode and the surface. Excess powder may be removed by suction or by use of a clean electrode with no powder. In the embodiment shown in Fig. 7, electrode 23 is surrounded by shroud 22. Powder 26 is delivered to the shroud by compressing bulb 29 so passing air through holes 28 and sucking powder 26 into tube 27. Suction pipe 21 is provided for removing excess powder. The powder may alternatively be introduced by attracting it on to the electrode, and presenting the coated electrode to the surface.
