Patent CA-1302141-C (CA)
Title: Covering for an opening with a cover or grating placed in a frame
Inventor: FERNS DEREK LORD LIGHTHORNE OF
IPC: E02D29/14
Filed: 1988-05-30
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE          The covering comprises a frame and a cover.  The cover has a conical, downwardly and inwardly inclined contact surface with which the cover is supported on a bearing surface arranged on a support flange of frame.  The bearing surface is also conical and inwardly inclined.  In the bearing surface are provided spaced, circumferentially distributed, wedge-shaped grooves, which cooperate with lugs on cover. Through the inwardly and downwardly inclined surfaces, a self-centring of cover is obtained, the centring being guided by lugs.  Thus, even in the case of high traffic loads, the cover is not moved from its position.

Title: Glaucoma drainage in the lacrimal system
Inventor: WHITE THOMAS C
IPC: A61F9/007
Filed: 1988-08-08
Granted: 1992-02-18
Abstract: ABSTRACT OF THE INVENTION A device and method for allowing fluid to flow from the interior of the eye into the nasolacrimal drainage system associated with the eye to relieve high intraocular pressure in the treatment of glau-coma.  The method employs a flexible tube having one end extendable into the anterior chamber of the eye and having its other end in communication with the nasolacrimal drainage system of the eye.  A one-way valve is provided within the tube to restrain liquid flow to a direction from the anterior chamber of the eye toward the lacrimal drainage system.  The method includes the steps of inserting one end of the tube into the anterior chamber of the eye and inserting the other end of the tube into a portion of the naso-lacrimal drainage system; aqueous humor is permitted to escape into the tube at the anterior chamber end, and flows outwardly into the passages of the naso-lacrimal system.  One or more one-way valves within the tube permit fluid flow only away from the anterior chamber.

Abstract: ISOLATION VALVE BYPASS FOR MASTER CYLINDER  BRAKE FLUID IN WHEEL LOCK CONTROL SYSTEM Abstract of the Disclosure A vehicle wheel brake system having a service braking section and a wheel lock control (ABS) section. Under certain conditions the wheel lock control section may not be able to generate sufficient pressure to operate the vehicle wheel brakes when the master cylinder output pressure has been isolated therefrom. When such conditions occur, the displacement piston of the ABS control section moves to open a bypass valve which connects master cylinder output pressure to the vehicle wheel brake even though the ABS system has isolated it from that wheel brake.  This therefore effectively returns the vehicle braking system to service braking until the vehicle operator releases the brake system.

Granted: 1992-09-22
Abstract: DATA INTEGRITY CHECKING WITH FAULT TOLERANCE               ABSTRACT OF THE DISCLOSURE Fault tolerant apparatus for generating error correcting code and, simultaneous therewith, checking the correctness of the generation, for blocks of data with which the error correcting code is associated and transmitted to a storage medium.  The apparatus includes a pair of programmable control devices configured to selectively operate in one of two modes:  A first mode in which data being transferred to the storage medium is monitored for generation of an error correcting code to be associated and stored with each data block, and a second mode in which the data being transferred is monitored for detecting errors that may be contained in the data.  During data transmissions to the storage device, one of the control devices operates in the first mode, while the other control device operates in the second mode to check operation of the first device. When data is retrieved from the storage device, both control devices operate in the second mode to check the correctness of the data being transferred, and the operability of each other.

Title: Aircraft propeller blade retention
Inventor: VALENTINE PETER L
IPC: F16C19/18
Filed: 1988-12-06
Granted: 1993-07-27
Abstract: Abstract Aircraft Propeller Blade Retention Preloading and retention of an aircraft propeller blade (12) are achieved by a preloading mechanism (85) received within an outer portion of a hub barrel (30) within which the blade is received.  The preloading mechanism comprises an annular fastener (90) threaded into the barrel.  A splined lock ring (125) prevents loosening or disengagement of the fastener from the barrel.  Location of the preloading mechanism at an outer location of the barrel allows the primary centrifugal load path from the blade into the barrel to be free from discontinuities and attendant stress concentrations.

Abstract: ABSTRACT     A roof anchor for supporting an underground mine roof or the like is provided.  The roof anchor has an elongated shaft with a head formed at one end.  The head supports a washer and a roof supporting plate that surrounds the mouth of a blind bore formed upwardly into the roof.  A resin capsule is positioned within the blind bore above the roof anchor. The shaft of the roof anchor has an adjustably securable annular  washer surrounding the shaft.  The annular washer is fixed in a position so that when the resin capsule is ruptured to release the resin to bind the roof anchor within the bore hole, the resin completely fills the bore hole from the blind end of the bore to the rigid annular washer fixed to the shaft of the roof anchor.  By making the position of the annular washer axially adjustable, the roof anchor may be utilized with varying amounts of resin as conditions at the mine site require and still cause the resin to be subjected to a compressive force within the bore hole in the space between the end of the bore hole and the annular washer.
