Abstract: A simplified system of recording and displaying input data signals having a multi-stage memory that provides a given magnitude output signal to a meter or recorder for each memory stage energized, with said memory having a stage, magnitude discriminator circuit, and a scaling network for interfacing signal inputs to appropriate memory stages, with a timer for resetting the memory stages to provide an update readout periodically to the meter, and with a direct display for displaying the particular memory stages that are energized, providing a direct display readout of the meter readings.

Abstract: A method of treating and/or preventing ulcerative colitis in humans by daily administering of between 1-6 grams of biological antagonists of Vitamin K generated either in vivo or in vitro by oxidation of tocopherols.

Abstract: A coaxial plug-and-socket type electro-optical connector for connection underwater. The male portion of the connector has an elongate alignment probe which includes a forward portion with an axially-tapered opening. A longitudinal electrically conductive probe mounted coaxially in the tapered opening has a forward tip housing an optically transmissive interface. The female portion of the connector has an elongate alignment probe mounted coaxially in it. The female portion alignment probe has a conically-shaped outer surface which fits into the male alignment probe's tapered opening to align the male and female portions. An electrically conductive receptacle is contained in an axially bored channel of the female probe; the receptacle has a socket which accepts the forward tip of the conductive probe. An optically transmissive interface is positioned at the rear of the socket entry and faces the male portion optical interface when the connector portions are joined.

Abstract: A pop-up sprinkler having a sprinkler head which is arranged in response to pressure water flowing therethrough to automatically elevate to a position above the ground for watering purposes and to lower itself to a position below the ground surface when the water pressure is removed, the sprinkler head being supported on a vertical movable riser tube slidably located within a tubular housing, the arrangement being such that during the ascent and descent of the riser tube, water flows across the outer surface of the riser tube and the inner surface of the stem to thereby flush same. Descent of the riser tube is aided by means of a spring having hooks at its upper and lower ends, with the upper hook attached to a legged spring clip abutting a shoulder on the riser tube, and the lower hook attached to a retention pin traversing the housing stem.

Abstract: A modularized roller assembly for holding a flexible, magnetically encoded card moving in a feeding direction through a channel against a curved transducer surface.
