Patent CA-2042007-A1 (CA)
Title: Digital optical switch
IPC: G02F1/313
Filed: 1991-05-07
Abstract: In a digital optical switch which is based on the mode-selectivity principle, made up of a passive section (A) containing a first optical wave guide (1) and a second optical wave guide  (2)  and a switching section  (B) containing a third optical wave guide (3) and a fourth optical wave guide (4), both the required asymmetry and the bringing of the optical wave guides within or outside each other's interaction region are achieved with the aid of curves (K1, K2) in said optical wave guides. In the switching section (B) said asymmetry is switchable. Use is made of the effect that a curve results, in general, in a reduction of the propagation constant in the optical wave guide. Suitable curves are of circular-arc shape and sinusoidal. The switching section (B) may furthermore incorporate a short intermediate section (s-u) in which the optical wave guides (12, 13) run straight at a small mutual angle (.PHI.) in the event that the switchable asym-metry is in the first instance too small with a par-ticular choice of material. The invention makes possible much shorter  switches which have a greater packing density.

Title: Hydraulic system on an injection molding machine
Inventor: HEHL KARL
IPC: B29C45/67
Filed: 1991-05-23
Abstract: ABSTRACT           CLAMPING UNIT AND HYDRAULIC SYSTEM FOR AN INJECTION MOLDING MACHINE        The hydraulic system comprises a 4/4-way valve, which is adapted to control the velocity of the mold-closing operation and the fluid pressure during said mold-closing movement and to assume three consecutive control positions, in each of which fluid pressure is applied to a stationary piston of an advance-retract cylinder from a first cylinder chamber, which is nearer to the mold. One of said control positions is a differential control position, in which pressure fluid displaced from the second cylinder chamber of said advance-retract cylinder, which second chamber is remote from the mold, is supplied to a pressure conduit through a branch passage, which includes a non-return valve. The differential control position is preceded and succeeded by a transitional control position, in which the pressure fluid displaced from the second cylinder chamber is returned through the 4/4-way valve to a reservoir. As a result of that arrangement the production rate of the injection molding machine can considerably be increased whereas only gradual velocity and pressure chambers are effected during the mold-closing movement.

Title: Method of recovering oil using continuous steam flood from a single vertical wellbore
Inventor: JONES LLOYD G
IPC: E21B43/24
Filed: 1991-05-28
Abstract: A method for recovery of oil from a subterranean, viscous oil-containing formation penetrated by one or more wells each of which is provided with at least two separate flow paths, the first flow path in fluid communication with the bottom of the formation from adjacent or below the formation and the second flow path in fluid communication with substantially the full vertical thickness of the formation. Steam is injected into the formation via the second flow path and fluids including oil are recovered from adjacent or below the bottom of the formation via the first flow path at a predetermined rate which is substantially less than the injection rate of steam so as to increase the formation pressure to a desired level. Formation pressure is maintained at the desired level while continuing injection of steam and production of fluids including oil until the fluids recovered contain an unfavorable amount of water. In a preferred embodiment, the tubing providing the first flow path may be progressively withdrawn or lowered into the wellbore to obtain improved steam-oil ratios and/or higher oil production rates. This method provides maximum gravity drive displacement of oil from the formation.
