Abstract: METHOD AND APPARATUS FOR RECORDING A SINGLE VIDEO FRAME     Abstract of the Disclosure A disc recorder having a single magnetic pick-up and record head and having a magnetic disc, rotating at the frame rate of a video signal, records and provides for display of a single frame from a video signal consisting of a series of video frames.  Motion jitter is eliminated by recording on the disc recorder one of the two fields which make up a chosen video frame and then reproducing this field.          The reproduced field signal is then stored and rerecorded onto the magnetic disc at a position relative to the original field recording corresponding to the delay between two inter-laced fields.  A memory having less capacity than that re-quired for storing a complete field signal is used with only a portion of a field being reproduced, stored and rerecorded during each rotation of the magnetic disc.  A complete video frame is thus recorded, ready for display, in which the two interlaced fields are identical.

Abstract: TITLE:  ROLLOVER APPARATUS FOR PLOWS      Abstract of the Disclosure A rollover mechanism for pivoting the plow frame of a two-way gang plow between alternate operative field positions angularly spaced 180 degrees apart relative to a center axis on a supporting three point hitch framework.  The plow frame is further positionable in an upright attitude for travel purposes.  Movement of the plow frame relative to a supporting wheeled carrier or three point hitch framework is accomplished through a crank arm connected to a plow frame pivot shaft.  An elongated lever arm is pivotally connected both to the crank arm and to an extendable hydraulic cylinder assembly mounted to the supporting three point hitch framework.  An intermediate link is pivotally connected to the three point hitch framework and is also pivotally connected to the elongated lever arm.  Straight line movement of the hydraulic cylinder assembly is thereby converted to angular movement of the pivot shaft.  Both the elongated lever arm and the inter-mediate link have side edges arcuately curved in a concave configuration facing toward the center axis of the pivot shaft.  This configuration allows them to be wrapped very closely about the pivot shaft to accomplish full 180° movement of the pivot shaft, as well as the plow frame and plows supported by it.

Abstract: 30.1.78 ABSTRACT:         A device for computer tomography in which a pa-tient to be examined is irradiated in different directions by a flat, fan-shaped beam of X-rays which is generated by an X-ray source having a comparatively small emissive surface area. The locally transmitted radiation is measur-ed by means of an X-ray detector comprising a series of de-tection elements which are arranged on an arc of a circle and which have a comparatively small radiation entrance surface area. A computer is used to calculate the density distribution of the irradiated part of the patient on  the basis of the measuring data. During an examination, the X-ray source and the X-ray detector rotate in opposite direc-tions about a common axis of rotation which extends trans-versely of the plane of the fan-shaped beam. The distance between the radiation entrance surfaces of the detection elements and the axis of rotation equals the distance be-tween the emissive surface of the X-ray source and the axis of rotation. Because the X ray source and the X-ray detector rotate in opposite directions, the patient to be examined is scanned by the X-ray source and a detection element in mutually substantially parallel, consecutive paths. Differences in the sensitivity of detection ele-ments do not become manifest as annular interference pat-terns in the calculated density distribution.

Abstract: ABSTRACT OF THE DISCLOSURE A scatter type of battery smoke detection includes a clock circuit applying energy pulses to an LED light source which directs light pulses on a smoke sensing path.  Smoke entering the light path scatters pulsed light to a photodiode whose output voltage varies with smoke density and corresponding light pulse level.  A threshold stage responds to photodiode voltage above a threshold level to generate a detection pulse.  The detection pulses and clock pulses are applied to a control circuit including a dual data-type flip-flop logic circuit, and thence to a threshold circuit driving an alarm horn. If the smoke density and hence the detection pulse amplitude exceed a pre-determined level, coincident application of the clock and detection pulses to the control circuit will cause the control circuit to respond by energizing the alarm continuously so long as the detection pulses recur at the clock frequency.  If a spurious noise voltage should coincide with a clock pulse the control circuit will energize the alarm, but only for the brief inter-pulse interval.  To reduce battery drain the inter-pulse is made relatively long by design of the normal clock circuit time constant.  But, to reduce the time that a spurious alarm can sound, the clock circuit time constant is shortened substantially when the control circuit responds to coincident pulses.
