Abstract: ABSTRACT: Device for determining internal body structures by means of scattered radiation.            The invention relates to a device for measur-ing a scatter coefficient distribution in a plane of a body. The plane is irradiated in different directions by a primary radiation beam along beam paths which are each time situated in parallel in a direction. Scattered radiation which is generated by a primary radiation beam along its path is measured by detectors which are situated on both sides of the plane and which enclose the body as completely as possible. The scatter coeffi-cient distribution is determined by iteration by cal-culating a scatter value for each beam path from an assumed distribution and by comparing this scatter value with the associated measured scattered radiation. From the difference between calculated and measured values a cor-rection is determined and taken up in the calculated value.

Abstract: Angle and Tilt Implement Assembly Abstract An implement assembly includes an implement, such as, for example, a blade of a work vehicle, pivotally connected to a frame for supporting said blade.  The blade and frame are closely positioned to the front of the work vehicle for maximum stability and balance of the vehicle. In the implement assembly the first apparatus tilts the blade generally vertically.  The second apparatus, such as, for example, angling cylinders, moves the blade to preselected angles relative to the vehicle.  A subframe is pivotally connected to the frame and second apparatus. The blade moves along the subframe during tilting and with the subframe to the preselected angles.  Use of the subframe substantially eliminates lateral movement of the angle cylinders during tilting for close mounting of the blade and frame without interference with the tractor while minimizing weight of the implement assembly.

Abstract: ABSTRACT OF THE DISCLOSURE             An apparatus and method for generating on demand a gaseous product from a liquid phase reaction of one reactant in the solid phase at ambient room conditions and another reactant in the liquid phase at ambient room conditions.  The reactants preferably are iodine crystals, and liquid tetrahydronaphthalene (THN), with the gaseous pro-duct being hydrogen iodide.  The liquid phase reaction, in the preferred embodiment, is 2I2 +C10H12 ? 4HI +C10H8. known per se.  Preferably, THN is pumped from a reservoir.  Some iodine dissolves into the liquid THN, withthe resulting solution then percolating through a reaction zone containing a heated, porous packing material.  Heat is transferred to the solution, thereby promoting, I.e., driving the above reaction.  The gaseous hydrogen iodide is then removed from the reaction zone; typically for direct use, for example, in a chemical laser.  The gaseous HI is generated at sufficiently high flow rates and/or partial pressures to be used in chemical lasers, eg., based on HF, HCl or HBr which operate at about 7200 nm, 3800nm, and 4100 nm, respectively.

Abstract: IMPROVEMENTS IN AUGER ASSEMBLY MOVING DEVICE            ABSTRACT OF THE DISCLOSURE         Relatively heavy and large auger assemblies often used in present day farming are difficult to move and ma-noeuver around a farmyard or the like and it is not always convenient to hitch a tractor to such auger assemblies for relatively short distance moving.  This invention includes a small electric or gasoline motor or engine which can be operatively connected to a small wheel which is mounted with-in a frame secured to the auger assembly framework and which engages the ground.  Means are provided so that this small wheel can be rotated in either direction.  A small castor-ing wheel assembly supports the rear end of the auger as-sembly and when the small wheel is operatively connected to the motor, the wheel may be rotated slowly thus enabling the auger assembly to be moved as desired.  Directional control is by steering the rear end of the auger assembly manually.

Abstract: ABSTRACT Apparatus for making the finishing cut on the internal outline of a rough cut female die has two carriages one sliding in one direction upon the other and the other carriage sliding upon a base at right angles to the first. A male punch comprising a template of the outline to which the die is to be finish cut is mounted on one carriage and the die or workpiece is mounted in an indexing work holder on the other carriage.  The template engages a tracer finger fixed relative to the base and to a hacksaw blade which finish cuts the die or workpiece by strokes with the plane of the blade perpendicular to the die surface being cut.  The tracer and blade are in common planes to which one carriage moves perpendicularly and the other parallel.  The cutter blade and tracer respectively engage the workpiece and template in the same direction so that cutting action urges the template and tracer into engagement.  A linear drive for one of the carriages is used for moving the workpiece carriage for cutting along linear portions of the die/workpiece, a linear portion of the template simultaneously moving along the tracer so as to urge the template and both carriages in a second direction normal to the first to the extent that the template deviates from linearity.  For cutting arcuate workpiece surfaces the template and workpiece are rotatably mounted on their respective carriages and turned by a rotary drive.  An adjustable eccentric coupled between the rotary drive and workpiece carriage translates the workpiece carriage during rotation to compensate for the displacement of the workpiece rotational axis from the axis of curvature of the arcuate surface being cut.

Abstract: 22,488 MONITORING AND SIGNALLING SYSTEM       ABSTRACT OF THE DISCLOSURE     A monitoring and signalling system.  The system includes a remote control unit in the residence of an individual and a centralized communication center interconnected with the remote control unit by a tele-phone network.  A plurality of sensors are located at strategic locations within the residence and operate to monitor the occurrence of particular activities performed by the individual and to produce signals in response to monitoring the occurrence of the activities. A microprocessor in the remote control unit receives and processes signals produced by the sensors and accum-ulates sensor activity data representing a running tally of the number of times each sensor has monitored its associated activities.  The microprocessor is also able to detect a prolonged lack of activity and to initiate an alarm sequence during which steady audible and visual alarm indications are provided in a pre-alarm period and followed by intermittent audible and visual alarm indications while an alarm communication is established and completed with the centralized communications center.  Response to the alarm communi-cation is provided at the centralized communications center.   The microprocessor is also able on a daily basis to initiate a self-check communication during which the sensor activity data corresponding to the various sen-sors is transmitted to the centralized communications center and processed to identify any sensor which failed to monitor an associated activity since the last self-check operation.
