Abstract: A method of establishing coincidence between a field size of a light field used in a setup mode of a radiation system and a field size of a radiation field used in an operation mode of the system includes providing automatic adjustment of field-defining structure to compensate for differences in optical properties of the light and the radiation. A light beam passing through the field-defining structure typically exhibits greater scattering than an X-ray beam passing through the structure. For each of a number of different settings of the field-defining structure, the difference between the field sizes of the light and the radiation are determined and recorded. Then, for a particular desired field size, the field-defining structure can be automatically adjusted to provide compensation. In the preferred embodiment, the field-defining structure includes jaws of a collimator of a radiation system and the determination of field size differences of the light and the radiation occurs for each of various energy level settings of the radiation system.

Abstract: A coupling system for corrugated, flexible metal hoses includes fitting and washer assemblies. The fitting assembly comprises inner and outer fittings, the inner fitting being received on the hose and having a bore adapted to receive the washer assembly. The washer assembly includes an O-ring, a backer washer and an expandable washer. The O-ring forms a seal connection with the flexible metal hose and the fitting assembly. The expandable washer provides a stop against which the backer ring is pushed by the O-ring. The expandable washer is also clamped between the fitting assembly and a corrugation of the flexible hose to resist withdrawal of the latter. Modified embodiment hose coupling systems are also disclosed and include inner and outer gaskets, compression gaskets, termination plates mounting the outer fitting and different combinations of retainer rings, backer rings and gasket rings. An application of the coupIing systems includes a fuel source, a fuel line, a manifold, the coupling system, a corrugated flexible hose and a gas-fired appIiance.

Abstract: A method of harvesting crops of the type falling in the genus Brassica comprises lodging the crops using a crop pusher assembly transported by a tractor and including a stationary crop pushing surface which is inclined downwardly and rearwardly from an upper top edge to a position adjacent the ground. The surface is convex and includes a bottom pivotal flap for following ground contour. The standing crop is moved to a lodged position against the ground without cutting or breaking the crop stems. This prevents shattering of the crop by maintaining the crop in the lodged position and causes the crop to continue to mature by maintaining the stems without cutting or breaking. After the crop has matured, the lodged crop is cut with a header of a combine harvester for harvesting the crop.

Abstract: A very compact interactive toy is provided that provides highly life-like and intelligent seeming interaction with the user thereof.  The toy can take the form of a small animal-like creature having a variety of moving body parts that have very precisely controlled and coordinated movements thereof so as to provide the toy with life-like mannerisms.  The toy utilizes sensors for detecting sensory inputs which dictate the movements of the body parts in response to the sensed inputs.  The sensors also allow several of the toys to interact with each other.  The body parts are driven for movement by a single motor which is relatively small in terms of its power requirements given the large number of different movements that it powers.  In addition, the motor is reversible so that the body parts can be moved in a non-cyclic life-like manner.  For space conservation, a cam operating mechanism is provided that is very compact with the cam mechanisms for the parts all operated off of a single small control shaft of the cam operating mechanism, e.g. approximately one inch in length, driven for rotation by the single, low power motor.
