Abstract: TITLE OF THE INVENTION:  Lubricating System and Method INVENTOR:  Donald R. MacLeod ASSIGNEE:  REXNORD INC., a Wisconsin corporation ABSTRACT OF THE DISCLOSURE:         A series of conveyor idler roll shafts in end-to-end relation supported by bearings provides a pressurized chamber for the flow of grease or oil to the bearings from a reservoir, which is capable of pumping the lubricant into the axial bore of each shaft.  Small, radially directed holes connect the shaft bores to the bearings by providing a restricted passage having across it a suitable pressure drop capable of allowing lubricant to flow in sufficient quantities to each bearing regardless of its distance from the reservoir pressure source.  Adjacent shaft ends are connected with a resilient cylindrical tubular coupler to provide the requisite flow passage continuity.  A labyrinth seal provides a continuous path for lubricant to flow through the bearings, the seal and ultimately to the ex-terior of the system, where its appearance is visible and indicative of adequate lubricant flow to each bearing along the shaft assembly.

Abstract: ABSTRACT     A method of immunoassay of a liquid sample in which a reaction mixture is formed and one or more components of the mixture are selectively removed by contacting the mixture with a particulate reagent comprising a polymeric matrix having a selective absor-bent material and magnetic particles incorporated therein.  By applying a magnetic field, the particulate reagent can be separated from the mixture.  The same particulate reagent may be used in a series of immuno-assays for different constituents of interest in liquid samples.  The method may be effected by discrete manual techniques or by automated continuous flow analysis.           The particulate reagents and their method of production constitute a further aspect of the invention.

Abstract: METHOD AND APPARATUS FOR HOLOGRAPHICALLY                  PROCESSING OPTICAL SIGNALS          Abstract A method and apparatus for holographically processing optical signals in a fiber-optic sensor system.  In the present invention, holographic processors are utilized in various combinations with light sources, fiber-optic transmission means, sensors and detectors to provide low cost, compact, sensitive and accurate sensor systems.  By means of the holographic processors of the present invention, the aforementioned sensor systems are used to monitor such physical parameters as temperature, pressure, flow-rate, and the like, and to provide output signal indications thereof that are compatible with digital receiving stations and immune to electro-magnetic inter-ference, hazardous atmosphere, and the inimical effects of inadvertent intensity variation due to equipment vibration and the like.  In one typical embodiment, a pair of holographic processors are employed in a color multiplex-demultiplex sensor system in which a first holographic processor is employed to color multiplex a sensor signal and a second holographic processor is employed to decode the color-multiplexed signal into a binary pattern that is then transmitted onto a set of photodetectors.  In each of the embodiments of the invention disclosed, a unique geometrical orientation of a hologram is utilized to minimize spurious signal interference that would otherwise hamper or totally preclude the holographic processing.
