Patent IE-812188-L (IE)
Title: Magnetic surveillance system
IPC: G08B13/24
Filed: 1981-09-18
Abstract: Apparatus for detecting the presence within a surveillance zone of a body of high permeability material creates a surveillance field varying sinusoidally at a fundamental frequency. Parallel filter channels select the second and third harmonic components of the perturbations created by said material when present in the field and the phase of the second harmonic relative to a reference signal is compared. The signal level of each of the second and third harmonic components as well as the aforesaid phase congruency cooperatively control an alarm circuit. Rhomboid shaped transmitter coils surrounding figure "8" receiver coils improve coupling to the high permeability body.

Title: Automatisk str°mningsregulator for variabelt behov
Inventor: LEON ERIC
IPC: G05D/
Filed: 1997-08-18
Abstract: En strømningsregulator (10) for variabelt behov regulerer vannstrømmen inn i en bygning (14) basert på variable vanntilførselstrykk og variable vannbehovstrykk. Når vannbehovet øker nedstrøms av strømningsregulatoren (10), avtar vanntrykket på nedstrømssiden av en stempelventil (200) og et stempel (201) i stempelventilen beveger seg i nedstrømsretningen. Dette fører til at et øket antall adkomsthuller (320) blir avdekket for vannstrømmen, som dermed gir en høyere vannstrømning når vannbehovet øker. En innstillbar lufteventil (500) styrer strømningskarakteristikkene for regulatoren (10) ved å påvirke stempelets (201) bevegelse.

Title: Nedsenkbar fiskemerd
Inventor: LIEN EGIL
IPC: A01K61/00
Filed: 1998-01-08
Abstract: En fiskemerd som kan senkes og heves igjen, kan vare utstyrt med en eller flere flyteringer som er helt eller delvis hul innvendig, og som har ventiler for inntak og utløp for vann, og innblåsning og uttak av luft, og som har innmontert tette eller perforerte skillevegger i flytaringene. Det nye ved fiskemerden er at to hovedskillevegger deler minst en av flyteringene på en slik måte at den består av en største horisontal sektor A og en mindre horisontal sektor B. Dermed kan den største sektoren av fiskemerdens flytering åpnes slik at vannet strømmer fritt inn i flyteringen samtidig som luften presses ut gjennom ventilene som står nær sektor B og holdes høyest i vannskorpen av sektor B. Fiskemerden kan henge på sektor B alene. Når del A har sunket, kan man foreta en balansert, kontrollert senkning ved å åpne ventilene i sektor B. Ved heving blåses sektor B først og kommer til overflaten. Deretter kan den største sektor A blåses tom for vann, og merden flyter igjen.
