Abstract: A method and system is provided for charting tooth decay to assist in caries management. Specifically, the invention provides a computer system, a Graphical User Interface(GUI), a method, and associated computer code for presenting an interactive tooth chart comprising selectable, anatomically correct tooth icons corresponding to a dental patient's teeth. The invention allows a user to select regions of each individual tooth icon to record the condition of the selected region. According to the invention, a dental patient is selected from a patient data base, the patent's teeth are examined, and the condition of each tooth region is recorded using selectable icons. The invention further provides automatic characterization of dental conditions based on standard values and previously recorded conditions to indicate progression of disease. In an alternative embodiment, the invention provides a recommended course of clinical management based on the information recorded.

Abstract: A refrigeration system comprising in closed series-flow relationship, a condenser, a capillary tube flow restrictor, and an evaporator including means connecting the outlet end of the restrictor to the evaporator inlet for reducing the noise generated by refrigerant flowing from the restrictor.

Abstract: A log splitting apparatus having an elongated frame, a selectively actuatable log moving ram mounted at one end of the frame, and a log splitting wedge assembly mounted at the opposite end of the frame. The wedge assembly includes a plurality of wedge tip sections which are removably mountable in vertically stacked relation and having interlocking lugs and recesses between mating upper and lower sides thereof for maintaining the wedge sections in proper alignment. A base plate is mounted on the frame for receiving and retaining the stack of wedge tip sections in proper orientation on the frame, and an upstanding support is mounted on the frame for vertically supporting the wedge tip sections and serving as a reactionary member for forces exerted on the wedge tip sections during log splitting. The wedge tip sections are further positively secured in mounted position by a vertically disposed clamping bolt threaded engaging the base plate.

Abstract: A walk from behind soil tilling machine including ground wheels upon which the machine may be moved and two rows of ground penetrating and pulverizing tines located to the rear of the ground wheels transversely to the line of machine movement. The tines of the rear row have a larger cutting diameter than the tines of the forward row, and the rows of tines are driven in counter-rotating directions such that upon forward movement of the machine the tines of the forward row break the surface of the ground and penetrate the earth to a determined relatively shallow depth and the tines of the rear row thereupon penetrate the earth to a further determined depth, with the forward and rear rows of tines cooperating to completely pulverize both depths of penetrated soil, thereby permitting thorough tilling of the soil to normal garden depth with a single passage of the machine.

Abstract: A friction clutch for a power driven element such as a rotary blade in which the element is seated on a drive shaft having a flange and an adjacent thread having an associated nut. Adjacent the driven element is a washer assembly which includes a rubber washer and a Bellville washer having its concave side faced toward the rubber washer so as to develop frictional clutching force between the shaft and the power driven element as the nut is tightened, the concavity of the Bellville washer serving to confine the rubber washer against radial expansion and the rubber washer, by its confinement, serving to prevent collapse of the Bellville washer upon severe tightening of the nut.
