Abstract: A method and apparatus for conditioning fluid flowing through a conduit in which two coils (50,60) are coiled around the conduit at different locations and connected to a circuit (40) which generates square wave signals which are alternately fed to the two coils (50, 60). The frequency of the square wave is ramped repeatedly from 1.5 Khz to 60 Khz.

Abstract: A press for compressing drums of contaminated waste. The press comprises a frame made up of a table and a crosshead connected to the table by means of vertical supports, and a compression assembly including a main cylinder secured to the crosshead. A main piston is situated inside the main cylinder and delimits a main chamber between the piston and the cylinder head of the main cylinder. The main piston is extended by a depending ram rod. A skirt is designed to surround the drum when it is being compressed by the ram. The skirt is extended at its top by a tubular piston slidably received in the main cylinder between the main cylinder and the ram rod. An intermediate chamber is delimited between the tubular piston and the main piston. An annular chamber is delimited between the tubular piston and the bottom of the main cylinder.

Abstract: A box (100) includes one or more housings (130) each of which is capable of receiving a memory module (MM). The memory modules have longitudinally extending side grooves and the housings are provided with corresponding module-guiding tongues (111) and 112). The back of each module includes orifices for engaging centering pegs (PC11 and PC12) to ensure that a male connector portion (C1) on the memory module is properly engaged with a female connector portion (C2) which is cushion-mounted at the back of each housing. A switch (IC10) detects when a module is fully inserted and the connectors are properly engaged. Complete insertion of a memory module is ensured by means of a toothed sector (121) engaging a rack segment (SC21) located at the front of one of the grooves. The toothed sector (121) is actuated by a lever (125) which closes across the front of the housing (130) and is locked in place by means of a screw (128) having a knurled knob (127).
