Method and apparatus for reduced glare observation of the eye fundus through optical lenses is accomplished by synchronized scanning illumination and observation of successive portions of the fundus. The scanning is conducted in rapid cycles to obtain continuous observation of the fundus and to provide for reduced glare photographs thereof.

The present invention is directed toward light-transmitting photochromic articles with low haze levels under illumination and processes for forming said articles without employing high temperature chemistry or heat treatments to initiate photochromism.

For making supported copper catalyst, useful in hydration of nitriles to produce amides, a cuprous compound e.g. cuprous chloride is impregnated into a support material, e.g. alumina, using acrylonitrile or acetonitrile as the imbibing solvent which is then removed by evaporation. The cuprous compound in the support is reduced to copper in situ, by contact with a reducing agent e.g. sodium borohydride.

A loader, including a vehicle frame, lift arms mounted on the frame for movement between upper and lower positions, and a bucket having a bottom, a rear and spaced sides, said bottom and sides defining a dumping opening, the bucket being mounted on the lift arms for movement therewith, wherein the improvement comprises a gate pivotally mounted to the bucket for movement between a first position wherein the dumping opening is unobstructed, and a second position wherein the dumping opening is part...

A flow directing apparatus for use in an axial flow turbomachine is disclosed. Techniques for reducing aerodynamic drag along the walls of the flow directing apparatus are developed. In one embodiment, rotor blades have multiplanar platform surfaces which reduce aerodynamic drag pressure losses at the interface between each blade platform and the adjacent structure.

A vehicle conveyor is provided with an upper wheel engaging active track and a lower inactive track. Rollers can be moved up by a roller up guide into the active track to engage the wheel of a vehicle for moving the vehicle along a path. The length of the conveyor is reduced by providing a roller down guide which can remove a roller from the active track along the length of the conveyor and by cycling the rollers such that the first roller on the active track engages the front wheel of a vehicle...

A pharmaceutical composition comprising abrin and nucleic acid wherein the ratio of abrin to nucleic acid is about 1:40 by weight is provided. The composition has less toxicity than abrin alone.

An elongated buoy with protruding external ribs extending about the circumference of the buoy. The ribs are oriented substantially perpendicular to the longitudinal axis of the buoy and create turbulence when the buoy is dragged upon the surface of the water. The turbulence results in decreased drag and permits easier and faster retrieval of the buoy by a crew member hauling in by hand a line attached thereto.

The present invention is directed to a process for the production of optionally cellular, polyurea elastomer moldings by reacting a mixture containing (I) a polyisocyanate component having an isocyanate content of about 10 to 30% by weight which comprises an isocyanate-terminated prepolymer prepared by reacting a polyisocyanate with a non-fatty, hydroxy polyester having a hydroxyl functionality of 1 to 4 and a molecular weight of about 500 to 4000, provided that if the hydroxy polyester is based...
