Title: Security Seals
IPC: G09F3/03
Filed: 1979-06-27
Abstract: A first cylindrical member (38) has an internal chamber into which a barbed prong (20) can be inserted. The prong extends from a circular or oval flange (12) and the chamber ends in a pair of shoulders (46, 48) behind which the shoulders of the barbed prong (22, 24) are snapped when the prong (20) is pushed fully into the member (38).

Title: Photographic formation of visible images
IPC: G06F3/02
Filed: 1980-01-21
Abstract: A visible image is photographically formed on a substrate employing a light insensitive layer 2 intermediate between a substrate 1 and a light sensitive photoresist top coat 3.

Title: Multi source cartridge
Inventor: FIDLER JOHN
IPC: F42B5/03
Filed: 1980-10-23
Abstract: A projectile for dispersing a material into the atmosphere at a target, which is designed to open in flight and scatter a number of independent dispersal charges over a limited target area, comprises a sabot in the form of a number of segments which are locked together prior to launching, which contains the dispersal charges and a delayed opening means which initiates opening in flight, thereby releasing the charges along approximately the same trajectory as the former projectile. In a preferred embodiment the sabot 1 is cylindrical, in two segments hinged together at their rear end, locked together by either a collar or a pin and socket arrangement, and containing a number of cylindrical charges 2 in line, with an axial channel. The projectile is fired from a gun, and firing initiates a pyrotechnic delay 4 which activates an explosive or pyrotechnic charge 5 in the channel and between the charges to open the sabot and activate and disperse the charges. Alternatively, the projectile may be thrown by hand or propelled by a rocket. The charges may disperse a riot control agent or smoke etc, and may have an independent delay. <IMAGE>
