Patent CA-2398716-A1 (CA)
Inventor: TSUKITANI MASAO
IPC: H04J14/02
Filed: 2000-10-06
Abstract: A wavelength dispersion compensation module for realizing high bit-rate signal transmission through simple arrangement and an optical transmission system including it. The wavelength dispersion compensation module comprises a wavelength dispersion compensator for compensating the wavelength dispersion of an optical fiber transmission line at a predetermined wavelength, and a temperature regulator for setting a desired wavelength dispersion value of the wavelength dispersion compensator by regulating the temperature thereof. With this arrangement, dispersion compensation control depending on variation in the wavelength dispersion of the optical fiber transmission line with temperature variation can be realized and accumulated wavelength dispersion over the entire optical fiber transmission line can be reduced effectively through a simple arrangement.

Title: Controlled release formulation of divalproex sodium
Inventor: CHESKIN HOWARD S
IPC: A61K9/22
Filed: 2002-08-23
Abstract: A new oral polymeric controlled release formulation suitable for the once-a-day administration of valproate compounds, such as divalproex sodium, has been discovered. This formulation exhibits significant advantages over the sustained release valproate formulations of the prior art. This formulation minimizes the variation between peak and trough plasma levels of valproate over a 24 hour dosing period. This formulation follows a zero-order release pattern thus producing essentially flat plasma levels of valproate, once steady-state levels have been achieved. This results in a significantly lower incidence of side effects for patients consuming such a formulation.

Title: Wide-field extended-depth doubly telecentric catadioptric optical system for digital imaging
Inventor: ALBERTELLI LAWRENCE E
IPC: G02B17/08
Filed: 2001-04-20
Abstract: Focused imaging of constant size and resolution over a wide range of distanc es and a wide field of view in object space is provided by a double telecentric  catadioptric optical system (100) including an external limiting aperture (1 4) at the juncture of the focal planes of two objectives (10,12), with a large- diameter concave or aspheric mirror (10) as the primary objective, and a camera lens (12) as the secondary objective. Constant resolution avoids rescaling of images made at different depths for machine recognition tasks such as OCR, saving computation time and cost, and increasing through-put an d accuracy. For digital line scan cameras, constant resolution of the image avoids scanning objects at different line rates for different depths of the objects being scanned, thus maximizing speed of the object and hence, throug h- put.

Patent CA-2410318-A1 (CA)
Title: Half ball valve
Inventor: OH SEUNG-JUN
IPC: F16K27/06
Filed: 2002-10-31
Abstract: A half ball valve includes a body including cavity having an assembly opening, a stem opening formed at a side of the body opposite to the assembly opening to connect the cavity and the outside, and a first connection hole inclined with respect to an axis of the stem opening. A valve element is accommodated in the cavity of the body through the assembly opening to be capable of rotating to switch between an open position at which the first connection hole is open and a close position at which the first connection hole is blocked. A passage is formed in the valve element inclined with respect to an axis of the stem opening and is connected to the first connection hole at the open position. A stem connects a control lever outside the body and the valve element along the stem opening. A body cap having a second connection hole connected to the passage of the valve element is coupled to the body to cover the cavity at the assembly opening side. A packing is interposed between an outer surface of the valve element and an inner wall of the body. Thus, the size of the valve element can be reduced and, when the passage in the pipeline is blocked, the fluid flowing in the pipeline is not confined in the passage of the valve element. Also, not only is dead space not formed but also the gap between the valve element and the body is completely sealed by the space filler, so that the fluid flowing through the pipeline is prevented from remaining in the gap and being deposited therein. Furthermore, the full bore concept can be realized in which no difference exists between the amount of the fluid that is coming in through the inlet and the amount of the fluid that is discharged through the outlet in the ball valve installed on the pipeline.
