Abstract: A pressure measuring device which utilizes an array of optical, non-acoustic pressure sensors with a laser light source which generates a pulsedlight signal into a light transmitting cable, wherein the pulsed light signal propagates along the light transmitting cable through the array of optical pressure sensors. A plurality of optical couplers are attached to the light transmitting cable at multiple locations spaced apart from one another in order to branch off at least a portion of the pulsed light each location. Each of the plurality of optical couplers includes a respective optical pressure sensor and a pressure insensitive reflector, wherein the branched off portion of the pulsed light signal is transmitted into to both the optical pressure sensor and the reflector. Each optical pressure sensor reflects a pressure indicating signal back into the optical coupler, while the pressure insensitive reflector reflects a reference signal back into the optical coupler. The pressure indicating signal and the reference signal are reflected through the optical coupler into the light transmitting cable as a pair of non-overlapping pulsed signals, which are then retrieved from the light transmitting cable by a signal detector. The retrieved pressure indicating signal is compared with the retrieved reference signal to determine the pressure acting upon the optical pressure sensor.

Title: Dispositif d'entree a obturateur et procede de moulage par injection
Inventor: MAI ARNOLD
IPC: B29C45/16
Filed: 1999-02-15
Granted: 2008-03-18
Abstract: L'invention concerne un dispositif d'entrée à obturateur et un procédé de moulage par injection. Le dispositif comprend au moins un obturateur disposé entre l'entrée et le canal de matière fondue aboutissant à la cavité du moule. L'obturateur se déplace latéralement entre une position fermée, dans laquelle le passage de la matière fondue de la buse à la cavité est empêché, et une position ouverte, dans laquelle ledit passage n'est pas entravé par l'obturateur. Entre ces deux positions, on peut employer l'obturateur pour réduire la section de l'entrée afin de la réguler par étranglement. Dans certains modes de réalisation, on utilise un seul obturateur ou une paire d'obturateurs pour attaquer l'entrée. Quand on utilise des paires d'obturateurs, ceux-ci, en position fermée, peuvent buter l'un contre l'autre ou se superposer. Cette nouvelle conception empêche la formation de déchets et évite d'avoir recours à un dispositif permettant d'éliminer les bouchons froids.
