Abstract: In root canal preparation, there is provided a smooth sided pilot ended endodontic K-type file, a K-type reamer file, a H-type Hedstroem file, an S-type file, and a R-type file (rhomboid), with the safe end of the instrument or file measured from D1 from 1-3 mm before the cutting edges are developed on all types of endodontic cutting instruments and on all sizes from 06-140.The smooth sided pilot end of the apex file can be incrementally increased based upon the increasing size of the instruments. For example, #15=1 mm smooth sided pilot end, #20=2 mm safe end, #25=3 mm smooth sided pilot end, etc. This is to be used for ease with the step back preparation technique. The smooth sided pilot ended apex file instrument has the ability to act as pathfinder into the root canal without damaging the apex portion during this phase.The smooth sided pilot ended endodontic file of this invention avoids forcing debris and filling material out the apex and creates a proper apical stop of proper retention and resistance.

Abstract: A conveyor belt is provided for carrying granular coal or ore from a mine or a crushing station, together with a belt heater in the form of a fuel burner which turns on to melt ice which as formed on the belt at temperatures below freezing. The belt heater heats the conveyor belt surface to a temperature sufficient to melt the ice film to form water and thereby prevent the granular coal or ore from sliding to impair the conveying operation of the conveyor belt or to cause spillage from the conveyor belt. When the conveyor belt stops, the fuel burner stops and thus prevents damage to the conveyor belt. A preferred fuel burner is an oil heater. An infrared heater can also be used but a fuel burner is preferred in flame contact with the belt. The flame of the fuel burner when used in direct contact with the conveyor belt can be immediately shut off when the conveyor belt stops and thereby prevents damage to the conveyor belt. The flame temperature or air temperature reaches a value of at least about 400.degree.

Abstract: This invention consists of a strip lug and nut remover consisting of a metallic semi-circular housing having a circular top and a semi-circular bore. The wall of the bore is provided with three sets of teeth spaced apart from each other and running lengthwise and/or longitudinally of the bore. A hexagon nut is positioned on the top of the strip lug and nut remover. The hexagon nut receives the open head of a hexagon shaped wrench. A plurality of spaced holes are provided in the top of the housing, and a smaller rotatable pin attached to a larger diameter eccentrically mounted pin is positioned in the bore with the small pin passing through one of the two openings of the top of the housing smaller pin is held in position by a snap ring. When it is desired to use the strip lug and nut remover, it is positioned over a damaged nut to be removed and the eccentrically mounted pin is positioned adjacent thereto.

Abstract: This invention provides several embodiments of a metal clip which is snapped onto a grid system and which anchors it through to place on a metal stud wall system. These metal clips makes it possible to erect metal studs of a housing and/or office construction without using electricity and without damaging the grid system so that the former can be removed and the ceiling of the construction does not have to be patched and/or replaced. In one embodiment of the metal clip, the metal clip has a pair of downwardly extending spaced spring sides connected together by a flat section. The spring sides are positioned over a cross metal beam and/or track. An upwardly extending clip is attached to the flat section and positioned in a fixed position for coupling of the grid system. In a second embodiment, the upwardly extending clip is made rotatable to connect to the grid system in different positions.

Abstract: A VCR protector is provided to prevent foreign objects from being inserted into a VCR tape entrance port of a machine when the VCR machine is not in use.

Abstract: An electronic component temperature monitoring system is provided for monitoring the temperature of electrical and electronic components and integrated circuit. This system, in one embodiment of the invention can consist of a temperature indicating decalcomania attached to the electrical and/or electronic component to be monitored. The decalcomania consists of a layer of nematic crystal material which as the time of manufacture is a milky substance. When the material is applied to a surface and let to dry, it becomes transparent and virtually undetectable. When the material is attahced to a electrical and/or electronic component, the crystal material reaches a set temperature, and becomes opaque in appearance and changes color with the fluctuation in temperature. The material is sandwiched between mylar, with a layer of adhesive opaque material is applied to the lower surface of the decalcomania. The combined layers are then cut into small sections.

Additionally, the sole protector is designed with an arch height of a standard boot.

Abstract: A portable crash-survivable kinetic flywheel storage machine which makes use of a ring shaped flywheel which is designed to be suspended by electromagnetic levitation. The structural and mechanical arrangement combine to allow functions which the unique electronic suspension system will interact with. The combination will allow rigid suspension and special crash stabilization capability, which is more important to the function of this particular invention than the efficiency advantage of the ring shape by itself. The flywheel is mostly composed of circumferentially wound fiber reinforced composite material. Induction loops are embedded in the skin of the flywheel, and a thin magnetic ring is positioned along the inside of the flywheel. This minimum excess mass is attached to the high strength flywheel in order to reduce the total parasitic momentum which will have to be controlled by the magnetic levitation system due to outside forces. A solid, hermetically sealed, physical enclosure surrounds the flywheel.

Abstract: A method and apparatus is disclosed for providing a replaceable pocket netting for a damaged lacrosse stick. The weaving lacing process of this invention is similar to the traditional pocket methods for maintenance of lacrosse stick. The button system is used on the leather thongs so that the pocket and its integrity can be salvaged from a broken lacrosse stick and used again with little effort. To take out this invention from the head of a lacrosse stick in which the pocket can be removed, it is necessary to untie and remove the side wall strings, untie shooting (throw) string at single hitch knot and at the correction attachment, untie the leather thongs at the bottom of the head. Then the pocket may now be removed from the unwanted head. To re-use the invention, it is necessary to rebutton the leather thongs at the top of the head, then the side wall strings and shooting string are applied. Finally, the leather thongs are retied at the base of the head at a desired pocket depth.

Abstract: In this invention for totally eliminating the fire and/or electrical hazards associated with maintaining batteries for both automobiles and aircraft use, a weighted disconnect link is connected to an internal battery cell jumper. This link is arranged to bridge the center two cells of the battery by positioning the weighted link into the spring clips of the cell bridge lugs, thus completing the circuit within the battery. The section of the battery that houses the weighted link will be totally isolated from the electrolyte and explosive gas. An access door is provided in the battery for contact cleaning and maintenance if it should be necessary. This door provides a means to re-engage the link manually after it has been tripped by adequate G force. The G force is the key to the functioning of the system.
