Title: Improvements in or relating to secondary-radar systems
IPC: G01S13/78
Filed: 1979-06-13
Abstract: In an arrangement for eliminating "fruit" interferences in a secondary- radar system using same-channel operation, the interrogating station is characterised by the use of an additional item of information (mark), in that the information, forms a part of the interrogation which causes a specific response signal to be emitted in the response device (transponder). in order to better suppress the reception of undesired responses in the interrogating station which results from the same-channel operation and at the same time to keep the outlay for the analysis of the mark as low as possible, a plurality of specific responses are made available in the transponder, from which, in dependence upon the mark of the particular received interrogation, in accordance with a calculating rule, a specific response code is selected and/or a conversion into another response code is carried out. Simultaneously to the interrogation the interrogating station response receiver is prepared in accordance with the same calculating rule for the reception of the selected response code. The calculating rule may change with time.

Title: Preparation of 2,2', 4,4', 6,6', hexanitrostilbene
IPC: C07C205/06
Filed: 1980-03-21
Abstract: 2,2' 4,4', 6,6'- Hexanitrostilbene is synthesised by reacting 2,4,6 - trinitrotoluene and sodium hypochlorite in an aqueous organic solvent in the presence of an additive, an alkaline earth metal oxide, hydroxide or carbonate. The preferred additive is calcium oxide, whilst the preferred organic solvents are either methanol alone or a mixture of methanol and tetrahydrofuran. The reaction is allowed to proceed for between 1 and 70 hours at a reaction temperature of between 8 DEG  and 30 DEG , both the reaction time and temperature depending on the organic solvent chosen. The product is isolated by standard methods in up to 47% yield. The addition of an alkaline earth metal oxide, hydroxide or carbonate to the reaction mixture removes the need for the critical control of the reaction conditions (eg pH, temperature) that is necessary in the previous syntheses of hexanitrostilbene.

Title: Antimicrobially treated fabric construction
Inventor: MORRISON WILLARD LANGDON
IPC: D06N3/00
Filed: 1982-04-15
Abstract: In a fabric construction having a backing fabric and a face fabric at least one of the fabrics is made at least in part of yarns formed from synthetic fibers which have incorporated thereinto an antimicrobial agent. In some embodiments a tie yarn joins the two faces in plated relation. Even with minimal contact of the yarns in the two fabrics, the antimicrobial agent migrates from within the treated fibers in the one fabric to the surface thereof and transfers to the yarns in the other fabric. Thus there is imparted antimicrobial protection to both fabric faces while maintaining the advantages of naturally occurring, untreated fibers in one of the fabrics.
