Patent NO-338106-B1 (NO)
Inventor: KOEDERITZ WILLIAM LEO
IPC: E21B44/02
Filed: 2009-02-12
Abstract: Methods and systems for controlling movement of a bit of a drilling assembly during reaming of an already-drilled hole; the methods, in certain aspects, including determining a ream speed for downward movement of the bit in the hole, moving the bit downward in a hole at the ream speed, determining a time period for deceleration of the bit to the hole bottom, determining a value for a target drilling parameter for drilling beyond the bottom of the hole, decelerating the bit (linearly or non-linearly) for the time period, and achieving the value for the target drilling parameter when the bit reaches the bottom of the hole.

Title: Høyttaler og høyttalersammenstilling
Inventor: SKRAMSTAD RUNE
IPC: H04R1/40
Filed: 2009-03-20
Abstract: En hornhøyttaler, særlig for å reprodusere basslyd i "public address" systemer, hvor hornet (23) er montert direkte til driverelementet (21) uten mellomliggende kompresjonskammer. Baksiden av driverelementet (21) er dekket av et bakkammer (24) som er laget med vegger av et halvgjennomtrengelig materiale. Veggene kan være perforert eller laget av et "lekkende" materiale, for eksempel celleskum med åpen struktur, eller et fibermateriale. Det "lekkende" bakkammeret vil hindre at det bygges opp for høyt trykk i bakkammeret ved store membranutslag. Hornhøyttaleren er egnet for stabling i grupper på to eller flere, slik at det kan lages en skalerbar lydkilde for gjengivelse av en hvilken som helst del av det frekvensområdet som kan høres av mennesker, for bruk i "public address" eller hi-fi systemer. På grunn av utformingen av bakkammeret, vil hornhøyttalerne kunne stables tett sammen, særlig høyttalere for høye frekvenser med konisk hornutforming. Dermed kan en slik lydkilde som består av en rekke slike tett stablede høyttalere, gi et homogent lydfelt som dekker et bredt område, selv ved høye lydfrekvenser.

Title: Magnetiske lagre
Inventor: HELGESEN GEIR
IPC: H02K7/09
Filed: 2013-05-27
Abstract: De foretrukne utførelsesformer av oppfinnelsen presentert heri er magnetlager som gjør bruk av magnetsammenstillinger med en høy magnetisk feltgradient. Magnetsammenstillingene anvender to permanentmagneter med motsatt polarisering i en åpen Kittel domenestruktur. Det underliggende prinsippet er beskrevet nedenfor med henvisning til figur 1. Den grunnleggende faktoren for magnetisk separasjon er magnetisk kraft, som virker på en partikkel av stoffet og som er proporsjonal med den magnetiske sensitiviteten av stoffet, verdien av den magnetiske induksjonen B og verdien av gradienten B av det påførte magnetfeltet. Derfor vil en økning av følsomheten og selektiviteten av den magnetiske separasjonen kreve bruk av de høyest mulige verdiene av magnetisk induksjon og magnetfeltgradient, eller deres forente faktor - produktet B B. Figur 1 viser et magnetsystem som har to permanentmagneter 2, 4 med motsatt magnetisering i form av en åpen Kittel domenestruktur. I et slikt system vil det, i nærheten av kantene av flatene som forbinder magnetene, vises et sterkt magnetisk spredt felt som er forårsaket av de ikke-diagonale matriseelementene av avmagnetiseringsfaktortensor, og verdien av produktet B B når 1011 mT2/m. På overflaten av magnetene, i sonen på de øvre kantene av forbindelsesflatene, vises det et sterkt magnetisk spredningsfelt med komponenter Hy (x, z), Hz (x, z), og Hx (x, z).

Title: Plant for thermally processing waste materials and method of operating such plant
IPC: C10B53/00
Filed: 1994-08-08
Abstract: A plant for thermal waste disposal includes a pyrolysis reactor having a first heating device for indirectly heating the waste and a second heating device for directly heating the waste within the pyrolysis reactor. The pyrolysis reactor converts the waste into low-temperature carbonization gas and solid pyrolysis residue. The low-temperature carbonization gas and the solid pyrolysis residue, possibly after passing through a treatment device, are fed to a high-temperature reactor for combustion. The first heating device ensures a basal heating of the waste in the pyrolysis reactor. A separate fuel or waste heat from the flue gas of the high-temperature reactor can serve the purpose of ensuring the basal heating. Supplementary heating is provided as required with the aid of the second heating device by providing an air feed into the interior of the pyrolysis reactor. A process is also provided for operating the plant for thermal waste disposal.

Filed: 1994-08-29
Abstract: In a paper-making machine a roll (22) is composed of two parts: a metallic base shell (38), which is constructed of conventional spun-cast steel alloy; and a thin outer shell (40) constructed of a material of high thermal diffusivity. The outer shell (40) is one to a few tenths of an inch thick and is in intimate contact with the surface of the steel alloy base shell (38). Typical materials of high thermal diffusivity for uses in the outer shell (40) are copper and aluminum. The roll (22) may be formed by flame spraying a layer of copper approximately two-tenths of an inch thick on the surface of a steel alloy base shell (38). The roll (22) is employed where improved heat transfer to a paper web is desired for example in an impulse paper dryer, or in a calendar.

Abstract: A radiator thermostat element (1) is disclosed, having a housing and a pressure chamber (2) arranged therein, which pressure chamber is enclosed by a capsule (3) and into which a corrugated tube (11) biased by a spring (15) projects. In such a thermostat element it is desirable to construct a safety device so that it can be mounted simply and with low undesirable variations. For that purpose, inside the corrugated tube (11) there is arranged a plunger (13) on which the spring (15) acts and which bears with one end against the base (14) of the corrugated tube. Further, between the other end of the plunger (13) and the spring (15) there is clamped a retaining element (18) which is arranged in a seat (19) in a housing element (7). <IMAGE>
