Title: Metodo per il controllo ed il ripristino del livello del liquido in un  generatore di vapore, e dispositivo che attua tale metodo
Inventor: FIERRO ALFONSO
IPC: F22B1/28
Filed: 1995-04-14
Abstract: Il metodo per il ripristino del livello del liquido evaporizzabile all'interno di una caldaia 1 di un generatore di vapore comprende la rilevazione della temperatura del liquido contenuto in una vaschetta 3, comunicante con la caldaia 1, da parte di mezzi rilevatori di temperatura 10, immersi in detta vaschetta 3, fino a quando il livello di liquida nella stessa non raggiunge un livello minimo LM.In tale situazione, i mezzi rilevatori di temperatura 10 sono e contatto col vapore, che si trova a temperatura più elevata rispetto al liquido, ed attivano organi di adduzione 30 di liquido dall'esterno verso la vaschetta 3, consentendo il ripristino di un livello operativo LO e, per conseguenza, il raffreddamento dei mezzi rilevatori di temperatura medesimi.Questi ultimi comandano a questo punto la disattivazione degli organi di adduzione 30, interrompendo l'immissione di liquido freddo nella vaschetta 3.

Title: Brønnutstyrsbeskytter.
Inventor: BRANDSDAL VIGGO
IPC: E21B33/12
Filed: 2013-02-05
Abstract: Oppfinnelsen vedrører en varmedeaktivert oljebrønnanordningsbeskytter som omfatter et lag av et materiale som er fast eller delvis fast ved temperaturene i øvre del og flytende ved temperaturene i nedre del av oljebrønnen der anordningen som skal beskyttes skal anvendes. Materiallaget kan med fordel anbringes slik at det dekker minst den øvre siden av anordningen som skal beskyttes. Beskytteren kan videre omfatte en fleksibel membran eller et ytterligere fast materiale utenpå materiallaget, og i tillegg eventuelt en viskøs væske. Oppfinnelsen vedrører i tillegg anvendelse av den varmedeaktiverte oljebrønnanordningsbeskytteren, som da anbringes på anordningen før anordningen føres ned i oljebrønnen, enten i forbindelse med produksjonen av anordningen eller som en etterinstallasjon. Det faste eller delvis faste materialet smelter når anordningen er nedført og installeres i oljebrønnen der anordningen skal anvendes, fortrinnsvis i den horisontale delen av oljebrønnen. Anordningen som skal beskyttes kan være hvilket som helst slags utstyr som skal nedføres i en oljebrønn, som kan skades under nedføringen ved kollisjoner med røret den nedføres i eller av objekter deri eller av fallende objekter i røret.

Title: Flytende forbehandlingssystem for kondensert naturgass
Inventor: JARIWALA ANKUR D
IPC: C10L3/10
Filed: 2014-06-11
Abstract: Et forbehandlingssystem og fremgangsmåte for et flytende anlegg for kondensert naturgass ("FLNG- anlegg") beskrives. Naturgass-innløpsstrømmen (19) strømmer gjennom et membransystem (30) for å fjerne karbondioksid og en varmeveksler (40), som produserer en første og en andre nedkjølt, CO2-utarmet ikke-permeatstrøm (41, 43). Den første nedkjølte, CO2-utarmede ikke-permeatstrømmen (41) blir ledet til ytterligere forbehandlingsutstyr, mens den andre nedkjølte, CO2-utarmede ikke-permeatstrømmen (43) blir ledet direkte til et LNG-tog (70). Alternativt kan naturgass-innløpsstrømmen (19) strømme gjennom et membransystem for å produsere en enkelt, nedkjølt CO2-utarmet ikke-permeatstrøm (71) som blir ledet til LNG-toget (70) etter nøytralisering og tørking. Siden forbehandlingssystemet leverer den innkommende gasstrømmen til LNG-toget (70) ved en lavere temperatur enn tradisjonelle systemer, er mindre energi nødvendig for å omdanne gasstrømmen til LNG. I tillegg har forbehandlingssystemet et mindre fotavtrykk enn tradisjonelle forbehandlingssystemer.

Title: Product coating apparatus in particular for coating tablets with gelatin film
Inventor: BERTA NORBERT I
IPC: A61K9/28
Filed: 1994-01-12
Abstract: The present invention is directed to an apparatus for coating a product (10) such as a medicament in the shape of a tablet. The apparatus includes a plurality of plates (50) for receiving and retaining the products and means for advancing the plates on a conveyor to various processing stations. At a dipping station, a dipping means lowers and raises at least one plate into a first coating tank (120) for coating at least a portion of the product. At a rotating station, a rotation means (70) rotates one of the plates containing the product for spreading the coating on the product. After rotation, a first elevator (302) transfers the plates from the conveyor (90) to a dryer (300) disposed above the conveyor. A second elevator (304) transfers the plates from the dryer back to the conveyor for further processing. The dryer includes complementary acting pusher bars (332) for transporting a plurality of plates horizontally along a plurality of vertically spaced guides. The plates are transported upward to traverse the guides through a first section of the dryer and downward through a second section of the dryer by the combined action of the first and second elevators and a mid-elevator (322). Several embodiments for the elevator are disclosed which include a lift bar mechanism (354), a continuous chain mechanism (376) and a lift rod system (400). <IMAGE>
