Patent NO-178777-B (NO)
Inventor: LANGOEY JOSTEIN
IPC: F28D11/02
Filed: 1994-05-09
Abstract: PCT No. PCT/NO95/00075 Sec. 371 Date Feb. 4, 1997 Sec. 102(e) Date Feb. 4, 1997 PCT Filed May 5, 1995 PCT Pub. No. WO95/30870 PCT Pub. Date Nov. 16, 1995A heat exchanger has been developed with a helical insert (9) permanently mounted in a housing (2). Between the windings in the insert (9) there is formed a helical channel (20) for one heat exchange medium. The insert (9) is designed with a channel (10) for the second heat exchange medium. The heat exchanger is designed with a central tube (13) which is axially movable and rotatable. The central tube (13) is designed with scraper elements for removal of deposits in the channel (20). In one embodiment the scraper element is formed by a helical insert (15) of the same design as the insert (9). The insert (15) is designed with a channel (16) for the second heat exchange medium. In a further embodiment the central tube (13) is designed with one or more scraper arms (23) which may be liquid-cooled. Deposits are often formed on the heat transfer surfaces. A cleaning cycle is performed by means of axial movement of the insert (15) which is mounted on the central tube (13) towards the permanently mounted insert (9), thus causing the heat transfer surfaces to touch each other. A rotating movement is then performed, e.g., a part of a turn, while the surfaces are close to each other or in contact with each other, thus causing the deposits on the two surfaces to be rubbed or scraped off and thereby cleaning the channel (20).

Title: System for å bedre dekningsgraden i et multifrekvens målesystem for klassifisering av objekter ved å syntetisere selektive frekvens- og posisjons-fordelingsplaner
Inventor: AARHOLT ELDAR
IPC: G01S/
Filed: 1994-10-07
Abstract: Fremgangsmåte for bedring av dekningsgraden i et multifrekvens system med én eller flere innretninger for mottagelse eller transmisjon av elektromagnetiske eller akustiske signaler ved én eller flere frekvenser eller ved én eller flere posisjoner, der fordelingen av minst to frekvenser eller posisjoner er gitt i en distribusjonsplan. Metoden finner sin anvendelse i system for deteksjon og måling av objekter i et medium av varierende eller tilnærmet konstant dielektrisk konstant ved bruk av spesifikke signalgenercrings- og signalbehandlings-metoder for bruk i eksempelvis konvensjonelle multifrekvens systemer som er basert på deteksjon og måling ved hjelp av elektromagnetiske eller akustiske bølger. Systemet kan anvendes i koherent forover- og/ eller tilbake-spredt og i så vel mono- som bi-statiske bruksmodi. Implementering av "Supcr-AK" algoritmer for generering av store antall syntetiske data-kanaler avledet av de i utgangspunktet utvalgte frekvensplaner øker mengden av tilgjengelig informasjon etter deteksjon. Avstanden til et objekt kan måles nøyaktig over tilnærmet et hvilket som helst avstandsintervall samtidig som objektets hastighet kan måles i tilnærmet alle sannsynlige hastighclsintervall. "Supcr-AK" teorien kan også anvendes på konfigurering av antennesystemer for å bedre strålingsdiagram og direktivitet.

Filed: 1989-07-25
Abstract: A novel three-step process for resolving a racemic spiro-hydantoin compound into its optical antipodes is disclosed, which involves (1) reacting said racemic compound with an optically-active asymmetric isocyanate of the formula RNCO, wherein R is (S)- or (R)-1-phenylethyl or (S)- or (R)-1-(1-naphthyl)ethyl, to form the corresponding diastereomeric ureido compound; (2) separating the resulting diastereomeric mixture into its component parts, and (3) thereafter converting the separated ureido diastereomers obtained in step (b) to the corresponding asymmetric hydantoin compounds by treatment with an alkali metal lower alkoxide (C1-C4), followed by acidification, whereupon the desired optical isomer is obtained. The final products so obtained, such as (4S)-(+)-6-fluoro-2,3-dihydro-spiro[4H-1-benzopyran-4,4 min -imidazoli dine]-2 min ,5 min -dione (sorbinil) and (5 min S)-3 min -chloro-5 min ,6 min ,7 min ,8 min -tetrahydro-spiro[i midazolidine-4,5 min -quinoline]-2,5-dione, are known to be useful in preventing or alleviating certain chronic diabetic complications.

Title: Character recognition methods including locating and extracting predetermined data from a document
Inventor: WUSTMANN GERHARD K
IPC: G06V10/20
Filed: 1991-09-20
Abstract: A method for automatically locating and recognizing amount data on a document by scanning the document to first locate a particular symbol, such as a dollar sign "$", and then using the located "$" to determine the document area containing the amount data to be recognized. Elements of the "$" symbol and amount characters are extracted from a gray-level image using binary seed and mask images derived using different gray-level thresholds. Operation is such that black pixels found in the higher threshold seed image are propagated in the lower threshold mask image to form connected components which are used for character recognition.

IPC: B29C33/12
Filed: 1995-06-09
Abstract: A method of positioning an ophthalmic lens in a holder (14) forming a concave recess (12), including the steps of conducting a fluid solution containing a surfactant into the recess, placing the ophthalmic lens (16) in the recess, and positioning the holder so that gravity forces the lens into a predetermined position in the recess. The carrier and the lens may then be transported to a lens inspection position, where the lens may be inspected to determine if it is acceptable for consumer use. The surfactant reduces the friction and the hydrophobic attraction between the lens and the surface of the holder forming the recess, helping to insure that the lens is pulled into the desired, predetermined position in the recess. <IMAGE>
