Patent NO-309628-B1 (NO)
Inventor: ZELLER MATHIAS
IPC: H02P6/34
Filed: 1994-08-09
Abstract: PCT No. PCT/CH93/00274 Sec. 371 Date Aug. 23, 1994 Sec. 102(e) Date Aug. 23, 1994 PCT Filed Dec. 7, 1993 PCT Pub. No. WO94/14219 PCT Pub. Date Jun. 23, 1994In the device, an electric motor is designed as a brushless, electronically commutated pancake motor (201) with permanent magnets arranged on the rotor and coreless windings arranged on the stator. Each winding is provided with a pair of terminals which can be connected in each case via a controllable switch at least to each phase conductor of the alternating power supply and to each other via a further controllable switch. In a device with pick-ups, the instantaneous voltage between one phase conductor each and a neutral conductor or another phase conductor of the alternating power supply, the instantaneous voltage between the two terminals of at least one pair of terminals, and also the instantaneous current in one winding each are repeatedly sampled. The sampled instantaneous voltages or currents are compared with one another and with corresponding threshold values in order to control the switches in dependence on the instantaneous result of the comparisons. The device allows a reversible conversion and storage of electric energy from an a.c. power supply into kinetic energy of an electric motor.

Title: Anordning for uttak av v¶ske fra en lukket beholder
Inventor: GESER JOHANNES
IPC: B65D77/06
Filed: 1999-10-15
Abstract: For uttak av en væske fra en lukket beholder (1) som i et bærbart apparat har en vekslende romlig stilling, må det treffes tiltak Slik at væsken kan tas ut uten problemer og mest mulig fullstendig. En lukket beholder (1) utstyres med et porøst lagringsmedium (5) med åpne porer og som er utformet som et legeme i ett stykke. Det fyller fortrinnsvis bare opp en del av beholderen, det befinner seg minst i området ved enden av uttaksrøret (4), og det berører i det minste av og til væsken. Lagringsmediet tjener som forhånds-lager for væsken og som boble- sperre. Det holder hele tiden en viss mengde av væsken i nærheten av enden av uttaksrøret, også dersom enden av dette ligger over væskeoverflaten i beholderen. Beholderen som er utstyrt med lagringsmediet kan anvendes som virkestoff-depot for et flytende legemiddel i en tåkedanner som er utformet som hånd- apparat, og ved hjelp av dette kan det dannes en inhalerbar aerosol.

Inventor: CALDWELL MELISSA CLAIRE
IPC: B26B21/00
Filed: 2001-06-22
Abstract: A hand-held dressing device has a blade with a sharpened cutting edge. The blade is preferably V- or U-shaped and permanently or removably supported by the limbs of a Y-shaped body with an extending hand group. The blade may be made from a single piece or form multiple segments with straight or curved cutting edges. The blade of blade segments may be fixed, such as by an adhesive, to a supporting carrier. Guard projections may extend from behind the cutting edge to beyond the cutting edge to reduce the likelihood of inadvertent contact with the blade edge while maintaining effective cutting action. In a method of use, the hair dressing device is manipulated so that the blade partly surrounds a cluster of hair strands and the device is moved to cut at least some of the strands of hair.

Title: Error elimination system for transmitted time information - uses information stored by slave clock during error correction
Inventor: STEUERNAGEL GERHARD DIPL-ING D
IPC: G04G5/00
Filed: 1977-01-17
Abstract: The error connection system is used for time information relating to the time in second minutes and hours and the date etc., transmitted in coded form from a control clock to a slave clock. The latter receives the time information at spaced intervals in serial or parallel form and checks the received time information for errors. When an error is detected during a checking cycle the remaining time information is stored until the error is corrected upon reception of the correct information during the following transmission cycle.

Inventor: MUELLER WILLY
IPC: H04M1/65
Filed: 1977-07-29
Abstract: To avoid gaps on the storage tape of the telephone call answering machine, the storage tape is rewound (F15) following the playback of a second part of the call answering text of the announcement tape (F11) after the recording of an incoming message (F10) on the storage tape but before the restoration of the standby condition (F1). The messages recorded on this storage tape are simultaneously monitored. Once the last recorded message has been identified, the magnetic recording medium is disabled and the standby condition (F1) restored by rewinding the announcement tape (F4). A virtually gap-free recording of incoming messages on the storage tape is thus achieved. <IMAGE>

Abstract: Molinillo de café perfeccionado Comprende medios para amortiguar el ruido producido por los medios para moler el café. De este modo, se reducen las molestias que produce el molinillo cada vez que se ha de moler café. Teniendo en cuenta que un molinillo de café convencional produce aproximadamente unos 81 dB de sonido mientras está funcionando, la reducción de decibelios conseguida con el molinillo de la invención es considerable al conseguirse reducciones de sonoridad de hasta 20 dB, siendo por lo tanto también considerable la reducción de las molestias para las personas que se encuentran en el bar o restaurante en el que se está moliendo café.

Title: Piece moulee fragile, obtenue par assemblage de parties en verre, en verre dur, et/ou de parties en vitroceramique, et procede pour sa preparation
Inventor: BEIER WOLFRAM
IPC: C03C27/08
Filed: 2000-02-11
Granted: 2002-11-01
Abstract: Pour assembler des parties en verre dur et/ ou en vitrocéramique, on utilise une matière d'assemblage qui est d'après l'état de la technique une colle aux silicones; cette colle aux silicones présente des inconvénients, en particulier lorsque la pièce moulée est soumise à des contraintes thermiques et est par exemple une surface de cuisson dans laquelle ou sur laquelle on prépare directement des mets.Conformément à la présente invention, on lie les uns aux autres les partenaires d'assemblage qui sont froids à l'état initial, au moyen d'une technique à haute fréquence, en introduisant d'abord entre les parties à assembler une matière d'assemblage qui est un produit métallique ductile, de préférence de l'argent, du cuivre ou de l'aluminium. On fait fondre ensuite la matière d'assemblage par chauffage par induction en appliquant un champ alternatif de haute fréquence et on presse l'un contre l'autre les partenaires d'assemblage. La matière d'assemblage donne ainsi une liaison très solide avec le verre dur ou la vitrocéramique.
