Abstract: A pivot pin assembly is disclosed which eliminates the need for a high pre-load torque to be applied in order to fix a friction-reducing element relative to the pivot pin. The pivot pin assembly includes a pivot pin having a shoulder formed on a central cylindrical portion thereof which is received in the bores of a forked member and in the bore of an intermediate member located therebetween. The pivot pin, has a conical surface at one end and is held fast in the bore of the other forked member by a collet which also has a tapered surface. The tapered surfaces of both the pin and the collet are mateable with the surfaces of the bores in the forked members as the collet is physically bolted to the pivot pin. A friction reducing element, having an inner and an outer race, is positioned about the central portion of the pivot pin such that the outer race is press-fitted into the bore of the intermediate member while the inner race is slidably received on the pivot pin and abuts against the aforementioned shoulder. An axial force is applied to the inner race by a compression spring which is positioned about the periphery of the pivot pin between the collet and the friction reducing element. The spring takes up slack between the collet and the pivot pin shoulder such that the conical surfaces can tightly interact. The spring also permits the friction reducing element to be held fixed relative to the pivot pin without requiring a high pre-load torque to be applied to the attaching bolt.

Date Aug. 4, 1986.A surgical apparatus for partially modifying the curvature of the cornea of an eye while the eye is within the patient is disclosed. The device is able to ablate a zone of corneal material in the form of a lenticular lamina. The thickness of the lamina at any particular point on the cornea surface varies as a function of the radial distance between that point and the central optical axis of the eye. The surgical apparatus comprises: a source of light (31) capable of emitting a beam of light (4) having a wavelength which is about 200 nanometers; an optical system (32) for directing and focusing the beam of light onto the desired zone of the cornea in order to ablate a lamina of material of the desired dimensions; and, a series of diaphragms and screens for obscuring varying portions of the zone of the cornea undergoing ablation in order to effect differential irradiation of the corneal surface. The longer the light beam (4) is allowed to impinge a particular portion of the cornea, the more corneal material removed from that spot and the greater the thickness of the lamina ( 2 and 16), and vice versa.

Abstract: The invention provides a new immersion head probe for use in apparatus for the determination of the concentration of gas dissolved in a molten metal. Such determinations are needed to facilitate removal of the gas, which can cause bubbles in the solidified metal and subsequent processing difficulties. The apparatus circulates an inert carrier gas through the probe in gas exchange contact with the molten metal to entrain dissolved gas until an equilibrium mixture is obtained; the concentration of the dissolved gas in the mixture then is representative of its concentration in the molten metal. The head consists of a monolithic or integral body of a porous gas-permeable material of sufficient mechanical strength at the temperature of the molten metal and of sufficient porosity, pore size and permeability to permit the necessary gas diffusion in a reasonable period of time. The body of the probe preferably is thin in one direction to minimize the path length for the gas to diffuse therein, and is provided with a carrier gas inlet and outlet suitably spaced apart to ensure that the gas diffuses throughout the body. If the test is to be carried out in a stationary body of molten metal, the probe may be vibrated or the metal may be stirred to increase the probe/metal contact, both decreasing the time required for the gas mixture to reach sufficient equilibrium.
