Patent IT-CS950005-A1 (IT)
Title: Elettromeccanico inerziale per l'attivazione di trasmettitori o altri dispositivi
Inventor: CACCAVALE BENEDETTO
Filed: 1995-03-10
Abstract: L'invenzione é un elettromeccanismo inerziale per l'attivazione di trasmettitore o altro dispositivo.Il trasmettitore si aziona automaticamente in seguito ad un urto di una certa violenza "registrato" dall'interruttore inerziale presente su molti veicoli a motore (è previsto l'azionamento manuale).Si consiglia di usare così l'invenzione nel campo automobilistico utilizzando il trasmettitore per inviare segnali di pericolo che possono essere ricevuti dagli altri autoveicoli. Tali segnali indicheranno un incidente o una situazione di pericolo generico.Il problema tecnico era quello di conciliare massima economicità e massima efficacia di funzionamento. Tale problema é stato brillantemente risolto mediante un congegno (l'elettromeccanismo inerziale) sia meccanico che elettrico il quale è fondamentale per l'attivazione del dispositivo finale (trasmettitore o altro dispositivo).

IPC: E01B31/17
Filed: 1996-05-09
Abstract: The profiling machine (1) is rolled along the rail (47) supported on flanged wheels (22) at each end. Swivel mountings (8) support a grinding frame (3) to position a grinding head onto the rail profile. Guide rollers (4) on the grinding head limit the amount of rail material taken off by the grinding head. The rollers tilt with the frame alignment about an axis parallel to the rail.

Title: Method of and apparatus for controlling operation of a multiple-chamber simultaneous filter
Inventor: SCHMIDT ROLF
IPC: C02F3/00
Filed: 1998-03-03
Abstract: In a water treatment process to operate a stacked multi-cellular filter bed, water flows in parallel through the cells, bearing suspended solids which are removed and/or converted by biological break-down. The flow of water into and out of the cellular stack is preferably regulated by opening or shutting the inlets to the cells maintaining the flow through the upper third (preferably the upper quarter) of the stack at 10-15 m/hour. When the flow speed goes below the minimum threshold, the filter bed which has the greatest flow resistance is back-flushed. The water flow speed through the individual water filter cell (2) inlet passages is monitored at measuring points (4) which are linked to a central monitoring unit (5), linked in turn to valves (6, 7) controlling the water inlets and outlets.
