Patent CA-2736292-A1 (CA)
Inventor: LI LI
IPC: G02B27/10
Filed: 2008-09-08
Abstract: Novel thin film optical filters have an in-tegral air layer. The frustrated total internal reflection (FTIR) phenomenon, combined with thin film interfer-ence, is used to effectively control the polarization prop-erties of thin film coatings operating at oblique angles.  The invention is applicable to high-performance thin film polarizing beam-splitters, non-polarizing beam-splitters, non-polarizing cut-off filters and non-polarizing band-pass filters, and any other thin film coatings that require the control of polarization effect. The low index layer of-fers an improvement in performance and the simplifica-tion of the thin film optical filter coating designs by re-ducing the total number of layers and the total layer thicknesses to minimize the angles of incidence and the size of the filter substrates, thereby minimizing the con-tact area and hence reducing the manufacturing costs.

Abstract: An insert for perforating a subterranean formation sealingly engages a port in a production casing run into a wellbore intersecting the formation.  The insert has a core where in a first mode it prevents fluid passage through the insert, and a second mode where the core disengages from the insert upon a treatment fluid reaching a threshold pressure in the casing, and ejects from the insert as a projectile to initiate and contibute to the fracture and stimulation of the formation by the pressurized treatment fluid exiting the port. The insert has a chamber which is filled with a gel that prevents wellbore cement from setting, and is covered by a perforated debris shield that permits the equalization of pressure between the chamber and the annulus between the casing and wellbore.
