Abstract: A tool for adjusting the volume of a hearing aid having a rotating dial. A method of adjusting the volume of such a hearing aid with a tool.

Abstract: A cutting blade is removably attachable to an adjustable height string trimmer assembly for a string trimmer machine. The line holder disc is modified by forming a large diameter concentric flange or shoulder about the central passage thereof, with the cutting blade being modified by forming a central passage therethrough having an essentially equal diameter to the shoulder of the line holder disc. A series of matched bolt holes are also formed through the blade and the line holder disc.

Abstract: An adjustable height cutting head for a string trimmer machine provides for the positive locking in place of the cutting string or line holder portion of the device, relative to a cylindrical central core which secures conventionally to the machine. The central core includes a series of adjustment holes of different heights through the wall thereof, with the collar of the line holder having a series of holes corresponding to any one of the heights of the adjustment holes in the central core. The height of the line holder disc is quickly and easily positively locked in place at the desired height relative to the central core, by securing a few bolts in the desired position. The present system precludes slippage of the line holder portion relative to the core, and moreover distributes the cutting lines evenly about the periphery of the line holder disc for proper balance of the assembly to preclude vibration and fatigue of the machine and operator.

Abstract: A burial compartment for two bodies comprises an outer container and two inner containers separated by two inner panels and a center panel. The burial compartment is configured so as to provide for burial of two bodies in a burial plot dimensioned for only one person. Moreover, the burial compartment makes it possible to provide a sealed inner container for a first, single body until subsequently a second body is placed with the first, at which time two separate inner containers holding the two bodies are easily joined, allowing for eternal rest of two bodies in a single, unified compartment. A method of non-contemporaneous burial is also provided.

Abstract: A device is provided which permits the simultaneous cutting or bisecting of a plurality of tires. Large, vertically mounted, circumferentially slotted wheels each adapted to receive a circular cutting blade in each slot, receive the tires. The cutting blades are mounted overhead on a shaft which traverses a pivotally mounted beam which is raised and lowered by a piston. A brake is provided for engaging the tread of the tire, and tensioning means engages the lower rim of the tire to exert a downward pressure when the overhead beam is lowered. Turning power is provided to the cutting blades by means of belts or chains which connect a motive source with the shaft on which the blades are mounted. Collars on either side of the cutting blades engage the tire tread when the blades are lowered to turn the tire. A plurality of slots and corresponding cutting blades can be provided for each wheel with spacers to determine the width of sections cut from the tire.
