IPC: A61C9/00
Filed: 1981-02-25
Abstract: For the production of a core for a root-filled prepared tooth the root canal (11) of the prepared tooth (10) is filled with an impression material (27) which is injected at the bottom of the root canal to successively fill the root canal from the bottom thereof and outwardly under expulsion of air therefrom. The injection is carried out with the aid of an injection needle (23) with an injection syringe cylinder (24) with piston (25) attached thereto, the cylinder being filled with said impression material and the injection needle serving as reinforcing element for the impression material, permitting extraction of the cast from the root canal after the impression material has set. In addition to the injection needle with the syringe cylinder and piston attached thereto the apparatus may comprise a mould (13, 14) formed as a guide for the injection needle (23) and adapted to be applied to the prepared tooth (10) for taking a simultaneous cast of the root canal (11) and the free prepared tooth surface (12) of the tooth.

Abstract: Les systemes de commande de transmission connus jusqu'a present, permettant un engagement automatique sequentiel des embrayages par fluide, possedent des soupapes commandees directement par l'operateur et ne peuvent pas etre facilement convertis de maniere a etre actionnes par un circuit pilote. La presente realisation possede une soupape (31) de selection mobile entre une premiere et une deuxieme positions permettant de mettre en communication une ligne d'alimentation (19) avec un premier et un deuxieme embrayages par fluide (11, 12) respectivement. Une soupape (44) actionnee par un fluide est deplacee jusqu'a une premiere position mettant en communication un troisieme embrayage (13) par fluide avec une ligne (18) de drainage lorsque la pression du fluide dans une chambre (61) de fluide descend au-dessous d'une valeur preselectionnee et dans une deuxieme position mettant en communication la ligne d'alimentation (19) avec le troisieme embrayage (13) par fluide lorsque la pression du fluide dans la chambre de fluide (61) depasse la valeur preselectionnee. Une soupape de vidange (76) fait baisser la pression du fluide dans la chambre (61) au-dessous de la valeur preselection nee en reponse a une chute de la pression momentanee dans la ligne d'alimentation (19) lors du deplacement de la soupape (31) de selection entre la premiere et la deuxieme positions. Un orifice (81) retarde le remplissage de la chambre (61) de fluide jusqu'a ce que l'embrayage selectionne entre le premier et le deuxieme (11, 12) soit engage. Les elements du systeme de commande sont actionnes par un fluide et sont effectivement commandes par un circuit pilote.

Abstract: A gas-insulated electric equipment such as a gas-insulated switch gear or gas insulated substation equipment, and more specifically an improvement in an earthing switch (500) built in a gas-insulated electric equipment. The earthing switch is provided with insulated guiding devices (52, 53, 54) which function selectively to electrically connect the electric contacts (211, 212) in the earthing switch (500) to an external device outside of the enclosure (501, 502) thereof in an isolated relation of the contacts from the enclosure while the enclosure is maintained gas-tight therein. When the earthing switch is turned on, that is, when the electric contact (511, 512) in the earthing switch is brought into contact with a mating contact (211, 212) on a conductor (201, 202), an insulation testing device provided with a test voltage source (70) can be connected to an end portion (541) of said insulated guiding device (52, 53, 54) outside of the enclosure. In this way, the conductor associated with the contact is tested with respect to its insulation.

Abstract: A dropout compensation system used with a video tape recorder, video disc, etc. is disclosed. In conventional modulation systems, a reproduced signal which has been modulated in a modulation system in which the signal information is determined by the zero passage of the carrier is delayed in the form of the modulated signal, and if a dropout occurs, the reproduced signal is switched to the delayed signal by a first switch thereby to compensate for the dropout. The phase of the modulated signal becomes discontinuous each time the switch is operated, thus causing an offensive spark-like interference upon demodulation. The invention is intended for reducing these noises and comprises a second demodulator (9) normally demodulating the delayed signal and a second switch (12) operated at a different timing from the first switch in response to the dropout. The noise is extracted by the operation of the second switch and the extracted noise is cancelled by being combined at opposite polarity with the demodulated reproduced signal which signal contains the noise but has been compensated for the dropout. A noise-removing circuit utilizing the horizontal correlation of the TV signal may be easily added to the configuration of the present invention.
