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.

Title: Ballast pour une lampe a decharge
IPC: H05B41/298
Filed: 1981-04-14
Granted: 1984-07-04
Abstract: Les lampes a decharge souvent reliees au reseau de tension alternative par un onduleur et un redresseur, l'onduleur travaillant avec une frequence d'au moins 10kHz. Il est ainsi possible de maintenir l'inductance necessaire pour la limitation de courant faible et en meme temps d'obtenir un rendement d'eclairage eleve. Toutefois, avec ce systeme, l'allure du courant preleve du reseau s'ecarte tres fortement de la forme sinusoidale. Afin d'eviter cet inconvenient on a deja commande le prelevement de courant a l'aide d'un regulateur a deux positions recevant la demi-onde du reseau comme valeur de consigne et le courant de lampe comme valeur effective. Avec ce ballast on evite la modulation de la tension de lampe avec la tension de reseau qui en resulte.

Abstract: Metallic clad glass fiber optical waveguide (10) suitable for use as a high-strength optical transmission line, e.g., for high capacity communications systems and for sensors operating at high temperature. At least two metallic claddings or coatings (13 and 14) are formed on the glass waveguide structure, which comprises a core (11) and glass cladding (12), by coating the glass fiber with at least one of the metallic coatings as it emerges from the furnace with a metal or alloy. The first metal or alloy (13) employed is one that is substantially chemically inert with respect to the material comprising the glass fiber at the deposition temperature during coating of the metal or alloy onto the glass fiber. The second metallic coating (14) may be of the same composition as the first, in order to repair pinholes or to increase the thickness. Alternatively, the second metallic coating may be of a different composition than the first in order to provide the waveguide with mechanical properties that are different than either layer alone could provide. Specific electrical and magnetic properties may also be provided. The metallic coatings prevent chemical or mechanical damage to the glass surface. A plastic coating (15) is optionally provided for additional protection of the metallic surface.

Abstract: A laser of the flowing gas type employs an optical resonator having mirrors at each end of the lasing region which are supported, without a separate optical bench, by a hollow cylindrical gas-tight housing. Enclosed in the housing are a pump for circulating the gas, electrodes for causing lasing of the flowing gas, and heat exchangers for cooling the gas. Those enclosed structures are subject to thermal expansion and contraction and are hung between a pair of plates. One of those plates is affixed to one end of the housing while the other plate is free to move within the housing so that thermal expansion and contraction of the enclosed structures does not place an appreciable stress on the housing. A heat shield is disposed between the hung structures and the inside wall of the housing to provide a barrier to the transmission of heat to the housing and the housing is liquid cooled to stabilize its temperature. The mirrors of the optical resonator are mounted on rings attached to each end of the housing. Apertures are provided in the plates to provide windows for the passage of light reflected between the mirrors of the optical resonator. At least one of the mirrors is mounted so that its alignment can be adjusted without opening the gas tight housing.
