Patent CA-2033618-A1 (CA)
IPC: F16B37/14
Filed: 1991-01-04
Abstract: A cover for a bolt and nut having a plurality of generally planar, annular surfaces comprises a shell including a closed end portion and a plurality of side surfaces extending downwardly from the closed end portion.  Each side surface has a generally planar inner wall that terminates in the bottom wall adapted for adjoining a flat surface of the wheel rim mounted on a vehicle with a plurality of such bolts and nuts.  The cover further comprises a clip for inserting into the cavity defined by the shell side surfaces.  This clip includes an annular ring and a plurality of spaced projections extending downwardly from the ring's perimeter, each projection adapted for engaging an annular nut surface when the cover is installed thereover.  The cover further comprises means for retaining the clip within the shell cavity.  Preferred retaining means include:  at least one inward protrusion from each inner wall against which a clip projection end section will engage when the clip is inserted into the cavity; and at least one pair of ring locators extending inwardly and axially along opposing inner walls of the shell.  On a preferred basis, this outer shell is made from chrome-plated plastic and the clip from a zinc-plated metal such as steel, brass or aluminum.

Title: Rapid miosis with control of intraocular pressure
Inventor: MCKINZIE JAMES W
IPC: A61K31/22
Filed: 1991-01-14
Abstract: Quick miosis with 24 hour control of intraocular pressure of patients undergoing extracapsular cataract extraction surgery is achieved by applying to the eyes of the patient during surgery acetylcholine as a first miotic agent and carbachol as a second miotic agent. Acetylcholine provides quick miosis while carbachol enhances the miotic effect while providing post-surgery control of intraocular pressure. The two miotic agents can be dissolved in a common saline carrier. The two agents can be combined in a unit dosage package by disposing acetylcholine in powder form in a first compartment and a solution of carbachol in a second compartment. The combined miotic agent of the invention is especially useful when substances which raise IOP such as viscoelastic agents are used during ocular surgery and/or with sensitive patients who enter the surgery with elevated pressure such as those suffering from glaucoma.
