Abstract: A rotary drag drill bit is seen wherein cutter bodies are rotatively connected to a main body structure at a fully offset position. The fully offset position is defined by a rotational axis of each cutter body, a longitudinal axis of the drill bit and end support points or positions of the cutter bodies. The rotational axes of the cutter bodies are perpendicular to the longitudinal axis of the drill bit. The end supports of the cutter body are each equal distance from any point on the longitudinal axis of the drill bit. The cutter bodies of essentially ellipsoidal configuration, being slightly thicker at a mid-portion thereof. Cutting elements are connected to flutes projecting above an outer surface of each cutter body. In a primary rotational direction of the drill string and drill bit, the rows abrade the bottom and side walls of a well bore as the cutter body attacks the earth formation as the drill bit is rotated.

Abstract: A stringed musical instrument embodies a matrix of intersecting frets and strings. A generally rectangular fingerboard mounts the strings and frets in a generally intersecting relationship thereon. The strings are tuned by string tensioning means, including tuning pegs. The string vibrations are amplified by an amplifier and sensed by a magnetic pickup. The strings and frets each define a number of notes, equal to at least the number of notes of an octave. In a first scheme of modulation, a plurality of strings are played along a single fret in a manner similar to a piano, the octave and key linear distance spacings as well as notes, being emulated. In a second scheme of modulation, different frets are played to obtain different notes, as in a guitar, to achieve a wide tonal range with easy fingering positions. Vertically adjustable magnets pick up the vibrations and are able to change the vibration sensitivity of the instrument.

Abstract: A lamp bulb mount for axially mounting two lamp bulbs into a light for selective operation in relation to a combination flood and spot light is disclosed. The mount includes a forward base and a rearward base selectively connectable to each other. The forward base is conformable to a reflector member of the light and has an opening formed therein which receives the lamp bulbs supported by the rear base. Interconnection of the forward and rearward base and placement of the forward base against the reflector member projects the light bulbs through the reflector member in a predetermined relationship. A socket of each base of the mount is convertible between flanged lamp bulbs and twin pin lamp bulbs through alternative spring mountings. A carrying case for the mount includes a fan adapted to maintain air flow throughout the light, cooling the battery, control circuitry and lamp bulbs.

Abstract: A trolley conveyor system chain for pulling trays of the conveyor through horizontal turns and climbing and descending grades. A link of the chain has a single pair of vertical and a single pair of horizontal wheels mounted thereon. A Y or vertical axis of the vertical wheels and an X or horizontal axis of the horizontal wheels intersect at a point and a link mechanism maintains the horizontal wheels in an ideal position relative to a chain rail assembly on which the wheels rotate and also aligns the chain to prevent collapse of the chain under tensile and compressive forces.

Abstract: A method and apparatus for forming an insulation blanket adapted for use in the accelerated curing of prestressed concrete is disclosed. Sets of feed rollers are positioned in equal numbers on opposite sides of a take-up drum. The feed rollers of each set carry a vinyl material forming an outer layer of said blanket. Each roller of said set is offet relative to the adjacent rollers so that the ends thereof overlap with respect to the adjacent rollers. An insulation feed roller feeds a heavy insulation medium layer onto the take-up drum. Equal numbers of sets of said feed rollers apply said vinyl outer layer to opposite sides of said medium layer. Adhesive is applied to each feed roller as the vinyl outer layer leaves said feed roller, providing means for joining the vinyl materials together and to the medium layer.

Abstract: A baby cradle supported on a pair of longitudinal rockers providing for head to toe rocking of a baby. When the cradle is not being rocked, as in an equilibrium position, the rockers maintain the cradle in such a position that a baby lying in the cradle is at all times head up relative to the feet.

Abstract: A fuel filter connectable in-line to a fuel system of an internal combustion engine has first and second separation means.

Abstract: A knife guide device for the opening of the paper cartons in general use for milk and other liquids. It is designed to work well with any sharp knife, and it works equally well right or left handed. It leaves a clean cut spout for pouring or drinking, and it does away with the heavy laminated paper flange sealing that part of the carton and with most of the fuzzy coat of the broken seal that remains when it is torn open with the fingers as originally intended. It makes subsequent openings and closings of the spout much easier and neater. The knife guide device comprises a guide surface with a slot that fits over and around the sealed flange of the container to be opened, a tang that hooks underneath the not to be cut end of the flange, and a handle with two gauge notches to indicate the exact point for the vertical cut to be made before applying the guide blade to make the horizontal cut of the paper flange.
