Abstract: ELECTRONIC CIRCUIT USING FIELD EFFECT  TRANSISTOR WITH COMPENSATION MEANS            Abstract of the Disclosure A compensation circuit for electronic circuits such as pulse generator circuits which are suitable for MOSICs includes a resistor of high resistance and parallel-connected MOSFETs of the enhancement type and depletion type, respectively.  The drain electrodes of the MOSFETs are connected to a power supply through the resistor, and are also connected to the gate electrode of load MOSFET of the depletion type which constitutes a load for a MOSFET of the enhancement type.  To the gate of the former enhancement type MOSFET, a controlled bias voltage is applied from the connec-tion point of MOSFETs connected in series between the power supply and ground.  By employing the compensation circuit in pulse generator circuits, the instability of the oscilla-ting periods due to changes in the ambient temperature and changes in the supply voltage is compensated.  Also, the differences of oscillating periods are decreased among MOSICs.

Abstract: ABSTRACT OF THE DISCLOSURE A method of restricting dust formation when coal, and particularly preheated coal, is fed into coke ovens is disclosed.          According to one aspect of the method, the coal is contact with an aqueous solution containing between 30 and 70 percent by weight of a substance which is capable of binding dust-like coal particles.          The contacting operation is performed prior to the introduction of the coal into the coke ovens.  The solution is used in quantities of 0.5 to 1.0 parts by weight per 1000 parts by weight of the coal.          The solution may include a surfactant and, further, may be mixed with coal tar.  According to another aspect of the method, the coal is simply contacted with 0.5 to 3 percent by weight of coal tar be-fore being introduced into the coke ovens.  Preferably, the coal tar is derived from the coking of the same type of coal or coal mixture as is to be fed into the coke ovens.  The coal tar is fav-orably heated prior to being contacted with the coal.  The coal tar likewise serves to bind dust-like coal particles.

Abstract: ABSTRACT OF THE DISCLOSURE           Parameters associated with a bus, which may be either an unshielded hollow conductor or a shielded hollow conductor, may be difficult to determine when the bus is carry-ing large currents at high voltages.  An indicator carrying a display is mounted internally to be visible through a window and thereby avoid conductors running from a high voltage region to an external place.  Thus temperature of the bus can be determined within the hollow conductor and can be used to activate a display adjacent an opening or window in the conduc-tor.  The display may be powered by a power supply mounted within the hollow conductor with the power supply deriving a voltage from longitudinally spaced points on the inner surface of the hollow conductor.  The current in the hollow conductor may be determined by measuring the IR drop between spaced points on the inner surface of the conductor, measuring the operating temperature of the conductor, determining the resistance from the measured temperature and the temperature/ resistance characteristic, and using the resistance and IR drop to determine current.  Similarly the IX drop can be determined by using a loop enclosing a longitudinally extending portion of the hollow conductor, and this in turn can be used to determine reactance if the current is known.

Abstract: ABSTRACT OF THE DISCLOSURE     In the placement of an anchor in the sea bed for mooring of a vessel a chaser in the form of a loop or hook is attached to a service line and the chaser is positioned on the anchor to support the anchor.   A service vessel with the service line secured thereto pulls the anchor and anchor chain from the parent vessel to be moored and simultaneously lowers the anchor to the sea bed via the service line.   The anchor is subsequently set in the sea bed for mooring and the chaser can then be removed from the anchor chain or returned up the chain to the moored vessel.      To retrieve the anchor, the chaser is run down the anchor chain until it engages the anchor, and the service vessel then pulls the anchor from the sea bed by means of the service line and takes the anchor aboard.   The anchor is then returned to the parent vessel.      The present invention provides a chaser wherein the chain engaging surface of the chaser is defined by an arc of radius R not less than twice the chain diameter (D) with the longest chord contained by the arc of length not less than 2.9D.   Additionally the chaser includes burial surfaces to produce burial forces transverse to the direction of sliding of the chaser.   This arrangement facilitates movement of the chaser along the anchor chain when in the sea bed, and also reduces wear on the chaser caused by rubbing on the chain.

Abstract: ABSTRACT         The hydrogenation of low rank coal to produce hydrocarbon liquids and gases is conducted in a first stage reaction zone at elevated temperature and pressure and without catalyst, followed by further hydrogenation of the total effluent in a second stage ebullated bed catalytic reaction zone which is maintained at slightly lower temperature.  The first stage may comprise an ebullated bed of high density non-catalytic contact material.          However, the presence of such contact material is not required.  Clarified hydrocarbon liquid streams are returned to the first stage reaction zone as the slurrying oil and to the second stage zone as recycle oil to maintain a significantly higher percentage of unconverted coal solids in the first stage reaction zone than in the second stage zone.  This two stage reaction arrangement produces a high percentage conversion of the low rank coal to liquid and gaseous products with good process operability.
