Abstract: BIASED REACTOR MAINTENANCE TERMINATION UNIT            Abstract A method and apparatus for locating faults in a transmission line on the customer side or network side of the apparatus as well as on both sides is disclosed.          A biased reactor maintenance termination unit is described that comprises a saturable core reactor, a permanent magnet and a termination network.  The saturable core reactor is connected in series with conductors of a transmission line.  The permanent magnet is placed adjacent to the reactor to create a bias mmf.  Finally, the termination network is connected across the transmission line conductors.          The maintenance termination unit responds to testing apparatus located at a maintenance center to determine fault location.  In response to an ac signal transmitted from the testing apparatus, a series of voltage spikes, are generated by the reactor.  The spike signal returns along the transmission line to the testing apparatus which includes oscilloscope and a spectrum analyzer.  The positive going spikes will not be equispaced from the negative going spikes but will be displaced due to the bias mmf effect of the permanent magnet.          Thereafter, a dc test signal is applied to the conductors to cancel the bias mmf created by the magnet. If the dc test signal value is of appropriate sign and equal to an ibias value of the bias mmf when the null condition occurs, the fault will be after the maintenance termination unit indicating a fault on the customer side. If the dc test signal value is greater than ibias value when the null condition occurs, then there is a fault on both the customer and network sides of maintenance termination unit.  If the bias mmf cannot be nulled by the dc test signal, the fault will be before the maintenance termination unit indicating a fault on the network side.

Abstract: ABSTRACT OF THE DISCLOSURE         There is described a marine propulsion device including a vertically tiltable propulsion assembly supporting a propeller.          The invention is concerned with a simple means for controlling the operation of a hydraulic cylinder or cylinders which perform both a trimming and a tilting function so that the propulsion assembly cannot be raised from a trim position to a tilt position under high propeller thrust conditions and is automatically returned from a tilt position to a trim position under high propeller thrust conditions.

Abstract: FLUID CIRCUIT MEANS FOR ELEVATING THE REAR END OF AN AIR RIDE TRUCK TRAILER          ABSTRACT Fluid circuit means to elevate the rear end of a truck trailer are incorporated in the air ride suspension means for the truck trailer and in communication with the air brake or spring brake fluid circuitry. The fluid circuitry provides manually controllable means to elevate the bed of the truck trailer at the rear thereof when the truck trailer is parked. The fluid circuitry is in communication with the spring brake fluid circuitry to prevent elevation of the truck trailer when the truck trailer parking brakes are not applied. The fluid circuitry provides a manually controllable connection bypassing the leveling valves to raise the truck trailer by admitting additional air under pressure into the air ride bags supporting the trailer. The fluid circuitry connections assure that the elevating system will be released and the excess air in the air ride bags exhausted automatically when the spring brake circuitry is pressurized to release the trailer parking brake. The connection with the spring brake circuitry is a safety feature in the event the operator does not release the manual control for the elevating means prior to releasing the parking brakes on the trailer.

Abstract: ABSTRACT OF THE DISCLOSURE A display system which is used as the input-output terminal of a data processing system which may be used for concurrent processing of application.  Each application may have a viewport on the display screen and viewports may overlap.  In order to write to low priority viewports without disturbing data displayed in those of a higher priority a mask buffer is used to prevent overwriting of high priority viewports.  More particularly, this application describes a multi-viewport system in which the writing of  application data into overlapping viewports is controlled by a screen manager.  The screen manager maintains a series of priority flags for each pixel (bit in the screen buffer) relating to the layers of the viewports, and a viewport order list.  Only the current, or higher priority viewport is written into by an application.  There is no provision for having more than one application writing into a lower priority viewport overlapped by the current viewport other than serially, i.e. writing to one viewport is completed before processing the next one. The main advantage of the present invention is that lower priority viewports may be written into requiring only a single pass over the data held in a data buffer, and it is able to handle the most complex of overlaid viewports.

Abstract: RD 15,014 METHOD OF, AND APPARATUS FOR, HALF-CYCLE-AVERAGE OR R.M.S. LOAD VOLTAGE CONTROL                  ABSTRACT OF THE DISCLOSURE         A sample of the voltage magnitude across a load, connected in series with an A.C. source and a load-curret-flow-control subcircuit, is taken during at least one of the time intervals when load current flows during a source waveform cycle.  The sampled load voltage is compared to a reference level and the difference in magnitude between the sampled and reference voltages is integrated, with respect to time, to provide an adjustment signal.  The adjustment signal is provided to a subcircuit for timing the conduction period of the load-current-flow-control subcircuit, by varying the conduction-termination time after each conduction-commencement (at each source waveform zero-crossing) to vary the selected one of the half-cycle-average (MAD) or RMS voltage magnitude across the load to a value such that the sampled load voltage magnitude is substantially equal to the selected reference voltage magnitude.  Several presently preferred embodiments are described for controlling the load magnitude in accordance with this method.

Abstract: ABSTRACT OF THE DISCLOSURE                 A METHOD FOR THE PREPARATION OF AN AMORPHOUS METAL OXIDE COMPOSITE      The invention provides a method for the preparation of a metal oxide composite, e.g. silica-alumina, having high uniformity and porosity in structure.  The inventive method comprises forming a homogeneous solution of at least two kinds of oxygen-containing organic metal compounds, e.g. metal alkoxides, in a solvent mixture containing a polar compound having multifunctionality or coordinatively crosslinking power, e.g. hexyleneglycol, together with admixture of water to cause cohydrolysis of the oxygen-containing organic metal compounds so that the homogeneous solution is converted into a sol and then into a gelled coagulum followed by drying and heating the coagulum to dissipate the polar compound. The method is applicable to the preparation of a solid catalyst containing a highly dispersed, catalytically active metal as one of the integral components in the metal oxide composite by the admixture of a readily reducible salt of the catalytically active metal to the solution before hydrolysis and heating the gelled coagulum impregnated with the metal salt in a reducing atmosphere to reduce the salt into the metallic form.
