Abstract: A dental template for positioning an object on teeth of a patient and method for fabricating the same. The method includes creating a digital model of the patient's teeth, creating a simplified template model based on the digital model, and fabricating the dental template based on the simplified template model. The template model is simplified by removing certain features of the patient's tooth anatomy. The dental template can be located on a patient's teeth using four or fewer positioning teeth.

Abstract: A diagnostic technique for monitoring shaft cracking or incipient pinion slip involves monitoring a shift in a characteristic natural frequency of an operating system such as a geared system of a locomotive. The technique involves monitoring a shift in the characteristic natural frequency or resonance of a shaft for detecting shaft cracking. The technique also involves monitoring a shift in the characteristic natural frequency of one or more assemblies of the operating system which include a pinion and detecting a shift in the one or more characteristic natural frequencies of the assemblies. A vibration sensor or measurement of current changes of a motor of the operating system can be used to detect vibrations to monitor the characteristic natural frequencies. Torsional oscillations or measurement of current and voltage changes of a motor of the operating system, can also be used to monitor the characteristic natural frequencies.

Abstract: An X-ray tube assembly includes a hermetically-sealed annular frame, spaced apart cathode and anode rings and an electron excitation device. The frame surrounds an exterior central passage for receiving a patient therethrough and has an interior chamber with a vacuum and an X-ray transparent window ring surrounding the central passage. The cathode and anode rings are stationarily mounted to the frame and disposed within the interior chamber. The cathode ring has circumferentially arranged side-by-side filaments each separately excitable by the electron excitation device to cause flow of electrons in an e-beam to a target portion of the anode ring such that an X-ray beam is produced that exits the interior chamber passing through the transparent window ring and that can be moved around the patient disposed within the central passage.

Abstract: A horizontal axis clothes washing machine. A rotatable clothes basket has a generally longitudinally extending and generally horizontally oriented axis of rotation and has two longitudinally spaced-apart ends. The clothes basket is rotatably attached to a generally surrounding tub which is suspended from a generally surrounding cabinet. Each of a pair of balance rings has a circumferential interior cavity, is attached to the clothes basket near a corresponding one of the ends, and has a generally longitudinally extending axis generally coaxially aligned with the axis of rotation. Tubes connect the cavity of one of the balance rings with the cavity of the other of the balance rings.

Abstract: An X-ray tube frame support assembly includes an annular support structure defining an interior chamber and having an interior surface surrounding and spaced radially outwardly from an X-ray tube frame disposed within the interior chamber, a quantity of cooling fluid contained in the interior chamber about the X-ray tube frame, and contact elements spaced from one another and mounted to the support structure so as to protrude radially inwardly from the interior surface into the interior chamber of the support structure and through the quantity of cooling fluid contained therein toward the X-ray tube frame such that the contact elements contact and hold the X-ray tube frame therebetween. Each contact element includes a body defining a hollow interior cavity and having apertures allowing passage of the cooling fluid into and from the interior cavity of the body for providing a passive damping of any vibrational movement of the X-ray tube frame.

Abstract: A horizontal axis clothes washing machine. A rotatable clothes basket has a generally longitudinally extending and generally horizontally disposed axis of rotation. The clothes basket is rotatably attached to a generally surrounding first member (which is a tub). A second member (which is a cabinet) generally surrounds the tub. At least two spaced-apart tub suspension subassemblies each include a cylinder, a rod, a piston, and a spring. The cylinder is attached to one of the first and second members. The rod has a first end positioned within the cylinder and has a second end attached to the other of the first and second members. The piston is positioned within the cylinder and is attached to the first end of the rod. The spring is positioned within the cylinder between the first and second ends of the rod. Preferably, a pair of balance rings are attached to the clothes basket.

Abstract: A rotatable subassembly for a horizontal axis clothes washing machine, such subassembly having a rotatable clothes basket and a pair of balance rings. The clothes basket has a generally longitudinally extending and generally horizontally oriented axis of rotation and has two longitudinally spaced-apart ends. Each balance ring has a circumferential interior cavity, is attached to the clothes basket near a corresponding one of the ends of the clothes basket, and has a generally longitudinally extending axis generally coaxially aligned with the axis of rotation. The cavities of the balance rings are in fluid communication with the clothes basket.
