Abstract: For disposing of liquid pig manure by composting same with solid carbonaceous matter. The composting material is contained in a trough, and is turned by means of an apron, which is supported in a carriage for a travelling along the trough. The apron carries moving rakes which lift and turn the material. The apron can be set to traverse both backwards and forwards. The apron is angled to a bottom-leading configuration during traversing, and the apron is capable of being lifted, to change the angle, when setting up for reversing the traverse.

Abstract: An electric device similar to a power strip and composed of an assembly of modular components with diverse functions, said modular components being fitted with cooperating mechanical and electrical interconnection means allowing to directly assemble them to each other. Said modular components consist of a front surface (1) with at least one specified function, of a contact support (5) wherein are mounted the means required to distribute the electric power, of a male end-fitting (2) and of a female end-fitting (3) comprising the mechanical and electrical connection means.

Abstract: An electric-power connector consists of a plug (1) and a female element, i.e. a socket (2), said socket (2) bearing the grounding pin if any and comprising a mask (3) moved by a return means into its closed position in front of said socket's orifices (40, 20) in order to render said socket inoperative by sealing its orifices, the socket's orifices becoming operative again when the mask shall be moved by an actuating means mounted on the plug (1), said mask (3) being kept in its closed position by a lock (6). Said lock (6) consists of elements which are distinct from the mask (3), and where called for the plug (1) is fitted with an inserted unlocking control means (7) which, when mounted on said plug, drives the lock (6) of the mask (3), the driving of the mask (3) being determined by the means mounted on the plug.

Abstract: Device for closing the end of a section (1) of U-shaped cross section having a bottom (10) and two flanges (12) provided near the open face of the section with a rail (13) turned toward said bottom (10), characterized in that it includes a ferrule (2) carrying on its lower side two lugs (21) and on its upper side two positioning nipples (22) and two hooks (23) having slots (24) and a stop piece formed by a spindle (3) engaging into the slots.

Abstract: Ionization of a medium being monitored is caused by an electric arc between a first pair of electrodes, while the conductivity of the medium between two measuring electrodes controls at least one feedback circuit which indicates relative rates of decay of the ions, as a function of variations in the number and mobility of ionized particles in the ambient medium.
