Patent ES-8100163-A1 (ES)
Title: Method and device for stamping
IPC: B41K3/12
Filed: 1979-10-15
Abstract: The documents processor uses a guide path for their supply from a magazine stack. It has an automatic stamp with a horizontally rotating inking drum driven by a servomotor in conjunction with position sensors for the document. The inking drum automatically aligns on the correct part of the document and applies the information to be stamped. The system is used for repetitive stamping or similar documents, such as bank codes onto cheques. The drum is set into rotation before the document has reached the stamping area. Thus the drum inertia does not affect the alignment nore the throughput. Two inking zones can be used for the drum to increase the versatility of the equipment.

Title: Plasma pyrolysis waste destruction
IPC: C10B53/00
Filed: 1984-09-11
Abstract: A method and apparatus are disclosed for the pyrolytic destruction of toxic or hazardous waste materials using equipment that is compact and transportable. The waste materials are fed into a plasma arc burner where they are atomized and ionized, and then discharged into a reaction chamber to be cooled and recombine into product gas and particulate matter. The recombined products are quenched using a spray ring attached to the reaction vessel. An alkaline atomized spray produced by the spray ring neutralizes the recombined products and wets the particulate matter. The product gas is then extracted from the recombining products using a scrubber, and the product gas is then burned or used for fuel. Monitoring devices are used to check the recombined products and automatically shut down the apparatus if hazardous constituents are encountered therein.
