Abstract: A gantry crane travelable along a pair of rails and having an overhead girder transverse to the direction of travel, first and second legs connected to the girder, a load carrying trolley movable along the girder to a first position adjacent the first leg and to a second position adjacent the second leg, first and second spaced apart motor drives mounted on one of the legs in engagement with one of the rails for moving the crane, and third and fourth spaced apart motor drives mounted on the other leg in engagement with the other rail for moving the crane.  When the trolley is at the first position, the first and second drives are highly loaded and the third and fourth drives are lightly loaded.      Thereby, the lightly loaded drives attempt to drive the second leg such that it leads the first leg and skews the crane.  When the trolley is at the second position, the third and fourth drives are highly loaded and the first and second motor drives are lightly loaded.   Consequently, the lightly loaded drives attempt to drive the first leg such that it leads the second leg and skews the crane.  A power source is connected to the first and third drives and a power source is connected to the second and fourth drives.   The power sources are responsive to the presence of the trolley at either its first or second position to provide a large portion of their electrical power to the highly loaded motor drives to prevent skew.

Abstract: A chain drive system is provided for communicating rotation from the bottom roller of a hay conditioner to the top roller of the hay conditioner. The top and bottom rollers include longitudinally extending flutes which intermesh as the rollers rotate. The top roller is mounted for movement at each end upwardly away from the bottom roller to accommodate increased quantities of crop or obstacles. The chain drive maintains angular synchronism between the rollers despite movement of the top roller away from the bottom roller. This is achieved using a single chain wrapped around a drive sprocket on the bottom roller and around two idlers arranged at the apexes of a triangle. The driven sprocket on the top roller is located within the triangle so that the chain wraps around the drive roller into the triangle, around the driven roller and back to the idler at the apex. The top roller is mounted for pivotal movement about an axis midway between the idler sprocket and the drive sprocket and located just outside a line joining the axes of those sprockets. This location of the pivot point and the proper selection of the length of the pivot arm maintains the chain path constant despite the movement of the roller and maintains the required angular synchronism.

Abstract: Disclosed is a primary door with window lights in the extreme upper portion. Optionally, the door can use a lowering window or a lowering screen self stored interiorly in a frame defined by the window track and the screen track and a lower stop in the upper half of the door. Thus the door can have a window, or a screen, or indeed can be left wide open for ventilation without diminishing the privacy afforded by the door since entire screen/window assembly is a plane well within the upper half of the door. In addition, replaceable decorative covers, such as muttons, are optionally on the outside and the inside of the door over the window area. The method relates to forming a door frame with a window opening defined by a frame and a cavity in the upper half of the door which contains the elements of vertical tracks for engaging the window and screen in a perpendicular horizontal stop for defining a frame for the window/screen assembly well within the upper half of the door. Optionally the door is formed as an inner and outer half, two halves being press-fittingly or otherwise secured to each other. Thereafter, the window and screen are inserted, and then decorative muttons or other coverings optionally applied.

Abstract: A transducer (10) for non-invasive transcutaneous transmission of pulsed ultrahigh-frequency acoustic radiation, in body tissue and/or fluids adjacent a bone fracture is "on target" when a fraction of the propagated energy within the longitudinal-response lobe of the transducer encounters a gap or space between closely spaced fracture walls. The ultrahigh-frequency acoustic radiation sees this "on target" feature as the entrance to a waveguide, whereby pulsed ultrahigh-frequency acoustic radiation is guided within the crack. When this acoustic radiation encounters a gap of at least a quarter wavelength (at the ultrahigh frequency), a standing wave condition establishes itself, with dissipation of the ultrahigh frequency and with demodulation to establish a therapeutically beneficial low-frequency acoustic condition, within the fracture, and acting where most needed, namely, on and between wall regions of adjacent fragments of the broken bone.
