Abstract: ABSTRACT OF THE DISCLOSURE           A directional coupler to be inserted into a line for transmitting wide band signals.  The line has a central conductor and a grounded outer conductor.  The coupler has an input terminal and an output terminal to be electri-cally connected to the central conductor of the line.  A first series transformer has a primary winding and a secon-dary winding, with one side of the primary winding con-nected to the output terminal of the coupler.  A second shunt transformer has a single winding connected between the other side of the primary winding and ground.  The single winding has a first intermediate tap connected to the input terminal of the coupler and a second intermediate tap connected to an output tap point.  The secondary winding of the first transformer is connected between the output tap point and ground.  Sample signals applied to the output tap point by each transformer are in phase when the transformers are energized by wide band signals travelling along the line in a direction from the input terminal toward the output terminal of the coupler and are out of phase when energized by reflected signals travelling in the opposite direction.  This invention increases the usable length of CATV transmission line without increasing the output level of the line amplifier.  It provides a direc-tional coupler having a relatively low tap value coupled with improved input to output impedance matching;  low insertion loss;  good directivity and good frequency response.

Abstract: SELF-LOADING BALE DISINTEGRATING MACHINE            Abstract of the Disclosure The machine has a normally upright, open top, rotary tub provided with a high speed, disintegra-ting rotor below the floor of the tub that projects through an opening in the floor to progressively reduce the mass of crop materials into disintegrated form as the tub rotates to agitate the mass.  The disintegrating rotor serves also as a means for blowing and forcibly projecting the disintegrated materials out a discharge spout as disintegration occurs, without the aid of an intermediate conveyor or the like.  The tub is mounted on a wheeled chassis in such a manner that it can be tipped essentially ninety degrees from its normal operating position to a lowered position in which the top of the tub is essentially vertically disposed, thereby permitting the tub to scoop up and load into itself a mass of materials as the machine is backed toward and into the materials.  After then swinging the tub back up to its operating position, the mass may be transported by the machine to a desired site for disinte-gration, whereupon rotation of the tub and activa-tion of the rotor commences the disintegration process.

Abstract: Abstract A current transformer is coupled about the power feed line of the motor operating a ball mill grinder or the like to sense the motor current.  This current is converted to a motor load or horsepower signal which is processed together with mill flow rate information of both raw materials and additives such as chemicals for improving grinding efficiency.  Thus, signals representative of mill operating efficiency are derived, and displayed in visual form having a relationship to internal mill conditions and optimum mill operating efficiency. Also the sampled signals are sampled and stored in digital form in a computer memory and in a tape recorder for processing and recall.  The samples are iden-tified by a recorded time signal.

The upper wall spans and is sealed relative to the upper marginal edges of the peripheral wall and includes a first elongated tab formed integrally therewith and downwardly tearable from the top wall into the container with one bendable end of the first tab portion remaining attached to the top wall.  An upwardly opening partition wall is disposed within the container below the top wall and includes peripheral edges sealed relative to the top wall.  The peripheral wall defines a closed chamber within the container below the top wall.  The partition wall includes a second integral elongated tab tearable therefrom with one bendable end por-tion of the second tab remaining attached to the partition wall.

Abstract: Abstract A system for monitoring the integrity of a cable, for example a cable for towing a variable depth sonar body through the ocean, is described. Such a cable comprises a core of electrical wires surrounded by load bearing wires which support through a terminator the sonar body.  For various reasons cracks can appear in the load bearing wires and in extreme cases one or more of the wires may break.  The monitoring system includes a transducer located near the terminator where the wires are most likely to crack or break and acoustic emissions caused by the incidence of cracks or breaks are picked up by the transducer.  The resulting electrical signals are amplified and passed up the electrical core of the cable to the towing vessel where they are processed.  Novel aspects of the system are the water coupling between the location of the cracks or breaks and the transducer and special processing circuitry which enables breaks, cracks and electrical noise to be distinguished from each other.
