Title: Method and appliance for production of dental bridges
Inventor: BOSS ANDERS
IPC: A61C13/003
Filed: 1995-06-30
Abstract: In the production of dental bridges, use is made of one or more wire-feeding tracks (12, 13). In a first manufacturing stage, supporting member parts (1, 2) are matched together by machining of contact surfaces with the said wire-feeding tracks. The relative positions of the contact surfaces are identified. In a second manufacturing stage, supporting member parts which have thus been matched are joined together using the identified information. A bearing member (8) is used, and the respective wire-feeding track (12 or 13) and the bearing member are mutually displaced so that the relative position of the track in relation to the said plane is altered. The wire-feeding track can in this case be made to cross the connection portions of the supporting member parts and can be brought into contact with the material in the respective supporing member part for establishing a contact surface (10 and 11). The identified positional information is obtained with the mutual positional relationship of the track and of the bearing member in a plane during the said first subsidiary stage.

Abstract: A retreat  restricting member  for  restricting the retreat of a pinion in an advanced state of the pinion on an output shaft and in a resulting meshed state of a pinion gear with a ring gear is engaged with a pair of pins rotatably, the pins being each attached to a thrust ring.   In a rotation restricting member for restricting the rotation of the pinion, upon meshing of the pinion gear with the ring gear, the front end of a rotation restricting bar is disengaged from a recess of a rotation restricting plate and falls to the rear end side of the thrust ring, thereby releasing the rotation-restricted state of the pinion.   Further,  engaging portions of the rotation restricting member come into engagement with engaging recesses of the retreat restricting member to hold the posture of the member, thereby inhibiting the retreat of the pinion.

Abstract: Dans un système (30) et un procédé de commande du fonctionnement d'un dispositif de sécurité pour les passagers d'un véhicule, en réponse à un évènement nécessitant éventuellement l'actionnement du dispositif de sécurité, on utilise des valeurs (36) mémorisées (34) et classées par ordre pour l'accélération reçue du véhicule, afin de générer (38) une mesure de secousse de classement élevé (j¿H?), une valeur d'accélération de classement moyen (a¿M?), et une mesure de vitesse de classement moyen (v¿M?), et l'on utilise également des informations d'accélération brutes afin de générer (40) une mesure (t') de "chronométreur par évènements" ou de progression des évènements. Ces mesures (j¿H?, a¿M?, v¿M?, t') sont ensuite utilisées pour générer (52 et 60) une paire de mesures d'identification d'évènements (m¿1?, m¿2?) utiles pour identifier deux types spécifiques de collisions pour lesquels des mesures spécialisées de gravité d'évènement basées sur l'accélération, autres que la mesure (m¿0?) de gravité d'évènement implicite, sont mieux appropriées spécifiquement lorsqu'une série de secousses négatives, se produisant relativement tôt dans un évènement à partir d'une accélération transitoire élevée, identifie la survenue d'un écrasement appréciable d'un véhicule, ou lorsqu'une série de petites secousses se produisant relativement tard dans un évènement, au-dessus d'une vitesses minimale, identifie un évènement de "chocs multiples".

Abstract: Un procédé visant à générer une espèce réactive consiste à exposer un photoréacteur polymoléculaire à un rayonnement, ce photoréacteur polymoléculaire comprenant un sensibilisateur spécifique d'une longueur d'onde, associé à un photoamorceur générant une espèce réactive. Le sensibilisateur absorbe l'énergie et transfert cette énergie absorbée à un photoamorceur qui, à son tour, génère une espèce réactive. Le sensibilisateur spécifique d'une longueur d'onde est conçu pour avoir une bande de longueur d'onde d'absorption correspondant généralement à une crête d'émission du rayonnement. Le rayonnement auquel le photoréacteur polymoléculaire est exposé aura généralement une longueur d'onde comprise entre environ 4 et environ 1 000 nanomètres. Ainsi, le rayonnement peut être un rayonnement ultraviolet, tel qu'un ultraviolet proche ou lointain ou un ultraviolet extrême: rayonnement visible: et un rayonnement infrarouge proche. De préférence, le rayonnement aura une longueur d'onde comprise entre environ 100 et environ 900 nanomètres. Dans un mode de réalisation préféré, le rayonnement aura une longueur d'onde comprise entre environ 100 et environ 375 nanomètres, dans ce cas le rayonnement peut être un rayonnement ultraviolet à impulsions, incohérent, émanant d'une lampe à décharge excimère à barrière diélectrique. L'invention se rapporte également à des procédés de polymérisation de monomères insaturés et de durcissement d'un mélange d'oligomères/monomères insaturé.

Abstract: Il a été démontré que certaines combinaisons de composés amphotères à base d'imidazoline substituée et de composés d'ammonium quaternaire présentent, outre leurs excellentes caractéristiques détersives, un profil d'irritation particulièrement réduit. Par ailleurs, il a été également démontré que certains agents tensioactifs amphotères à base d'imidazoline substituée, en combinaison avec le chlorure de didécyldiméthylammonium (DIDAC), présentent une réduction inattendue de l'irritation synergique par rapport à celle observée lorsque l'ammonium quaternaire est du type chlorure d'alkyldiméthylbenzylammonium (ADBAC). Les désinfectants et agents d'assainissement peuvent ainsi être formulés avec l'agent antimicrobien préféré tout en présentant un profil d'irritation potentielle réduit de manière optimale.

Title: Generalized fast, power flow controller
Inventor: GYUGYI LASZLO
IPC: H02J3/06
Filed: 1994-08-11
Abstract: First and second dc linked, preferably voltage sourced, inverters are connected to an electric power transmission line in shunt and in series, respectively, by coupling transformers. Firing of the GTO-thyristors of the first inverter is controlled to regulate reactive power on the transmission line and to supply real power requirements of the second inverter. The second inverter is controlled to inject into the transmission line in series a voltage which can be adjusted in magnitude and from zero through 360 degrees in phase with respect to the transmission line voltage to selectively adjust any one or more of transmission line voltage magnitude, transmission line impedance and transmission line voltage phase angle. In a high power configuration of the controller each of the inverters includes a plurality of six-pulse inverter modules connected by interstage transformers to form balanced higher order pulse groups controlled through pulse width modulation or through adjustment of the phase between opposite groups to generate the appropriate ac voltages.

IPC: C08G67/02

Abstract: Carbon monoxide and ethylene are polymerized in the presence of a catalytically effective amount of a catalyst formed from a Group VIII metal source, such as palladium, a bidentate ligand containing a Group VA or VIA  heteroatom, such as phosphorus, and an anion which is a non-coordinating, non-acidic tetrasubstituted anion containing a Group IIIA element, such as boron, with the anion preferably being either an unsubstituted or substituted boron tetraphenyl compound. The catalyst is advantageously formed by the exchange reaction of a ligand-conjugated Group VIII metal salt with a salt containing the non-coordinating, non-acidic tetrasubstituted anion containg the Group IIIA element in a solvent medium which causes the separation (due to differing solubilities) of the desired catalyst from the by-product of the reaction which comprises the anion from salt which was used as the Group VIII metal source and the cation from the salt used as the source of the non-coordinating, non-acidic tetrasubstituted anion containing the Group IIIA  element. The resulting polyketone product has novel thermal stability characteristics.
