Abstract: ABSTRACT OF THE DISCLOSURE           Spring retaining clips formed of spring wire firmly hold a screen deck to a plurality of mounting bars on a vib-rator.  The clips each have facing, semi-circular upper and lower end portions connected on one side to slightly angled connecting portions which are joined by a central loop portion. As a clip is mounted over a support rod on the bottom of a screen deck and under a mounted bar on the vibrator, its ends are forced apart causing the angled connecting portions to become vertical as they move toward contact with a vertical side portion of the mounting bar.  Additional separating forces applied between the ends of the clip during vibration of the screen deck after the connecting portions have become vertical are strongly resisted by the ever increasing force exerted by the central loop portion which must assume a smaller diameter as the end portions move apart.  The central loop portion is formed so as the have a maximum outer diameter when the clip is in its free state which is less than one half the distance between the semi-circular configurations of the end portion.

Abstract: ABSTRACT OF THE DISCLOSURE     It is known to utilize a screed extension apparatus along the front surface of a mold board in a machine for spreading pulverulent material such as a paving machine.  Such a screed extension apparatus normally includes a strike-off plate and means for mounting and moving this plate between a retracted position generally in front of the mold board and an extended position in which the strike-off plate extends from an end of the mold board so as to serve as an extension of the mold board.  Such a structure can be improved by utilizing two housings, the second of which fits around the first in such a manner that the second housing may be moved linearly with respect to the first but is restrained from any other type of relative movement with respect to the first housing.  The first housing is secured in front of the front surface of the mold board well above the bottom of the mold board and adjacent to the end of the mold board.  The second housing carries the strike-off plate.  Preferably a hydraulic cylinder is located in the first housing and is operatively connected to the second for use in moving the second housing relative to the first housing.

Abstract: APPARATUS FOR CHANGING THE DIRECTION OF A THREE-PHASE PIPE-TYPE GAS-PRESSURIZED ELECTRICAL CABLE     ABSTRACT OF THE DISCLOSURE     A direction-changing arrangement for a three-phase pipe-type gas-pressurized electrical cable constituted principally by rigid straight pipe lengths connected in series and wherein the axes of the three phase conductors supported within the pipe when viewed in cross-section form a triangle.  The desired change in direction is accomplished by interposing a spherical elbow pipe between two straight pipe lengths which includes a pair of branch pipe stubs connected to the ends of the adjoin-ing straight pipe lengths, and three curved conductor members supported within the elbow and arranged symmetrically to the plane formed by the respective axes of the two branch pipe stubs which intersect at the center of the elbow.  Three intermediate conductor sections are provided and these serve to interconnect the ends of the three inner conductors within the adjoining straight pipe lengths with the ends of the three curved conductor members within the elbow.

Abstract: ABSTRACT OF THE DISCLOSURE         A control system for energizing and de-energizing an external load in series with a source of electricity incorporates a rectifying net-work having inputs in series with the alternating current source and the external load.  An electronic switch of the system activates the load by effectively shorting together the inputs to the control system when the combination of externally sensed parameters obtain predetermined magnitudes. The sensed parameters control the activation of the electronic switch by a plurality of control modules which interact with a control logic module, representing a Boolean combination of the control module outputs, so as to activate a trigger module which in turn causes the electronic switch, such as a silicon controlled rectifier (SCR) to be triggered.  The external load is then energized by the SCR effectively shorting the inputs to the control system and which thus completes the electrical path from the source of electricity through the load.  The control modules may optionally be connected to external control signals for their activation or de-activation and may also incorporate a hysteresis effect with respect to the sensed parameter.  In a preferred embodiment of the present invention, the control system senses temperature and light, so as to override an existing furnace thermostat switch during the day and other times when the room is lighted and to return furnace control to the thermostat switch at some other, lower, temperature during the nighttime when the lights in the room have been extinguished.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is a gyroscope operated in a strapped-down mode and mounted on a float assembly with its spin axis extending in a vertical direction.          The float assembly is free to pivot through small angles about any horizontal axis but is constrained from rotating about the vertical spin axis to assure an accurate azimuthal reference between the gyroscope and the casing in which it is floating.          The angle between an azimuthal reference line of the gyroscope and true north is obtained by measuring the magnitude of torque required to counteract precession of the gyroscope about a horizontal sensitive axis which would occur because of the horizontal component of the rate of rotation of the earth.

Abstract: ABSTRACT               A lateral register control system utilizing a reference lateral and circumferential mark pair preprinted on the web which is compared with a corresponding mark pair mounted on a drum coupled to the shaft of the print cylinder whose reference is to be controlled. The clock source being an encoder connected to the same print stand as laid down the reference marks on the web.          The contents of the cylinder position counters always being slightly greater than the contents of the scanner difference counters and being counted up slightly before the scanner difference counters.       Upon sensing a first reference mark on the web, the scanner difference counters are permitted to count. Upon the second reference mark being sensed the fine adjust counters are permitted, to start counting. Upon the contents of the fine adjust counters equaling the value of operator settable fine adjust switches, an error pulse train is generated having an associated sign. The error pulse train is accumulated in a repeat counter and is terminated when the contents of the scanner difference counters equal the contents of the cylinder position counters. Said error magnitude may be averaged over several cycles or output directly to a digital analog converter which produces an analog error magnitude. This magnitude serves as the input to the motor control circuitry. Said motor control circuitry being operable to drive the print cylinder lateral position motor at a rate proportional to said analog error signal and in the direction indicated by the sign of said error signal.
