Abstract: A shaving cartridge including spaced-apart first and second razor blades each having an elongated edge formed thereon for cutting and shaving whiskers and hair, a container for retaining the blades therein and presenting the cutting edges at an angle for shaving action against the skin, the cartridge having formed therein a pass-through aperture between the blades allowing passage of shaved material away from the cutting edge to allow movement of the blade over the skin free of accumulations of cut material.

Abstract: A process for making a toothbrush having three brush heads that self-adjust to maintain contact with the surfaces of the teeth and the gums. The three brush heads are independently attached to a single handle through elongated flexible arms and adjust independently to maintain contact with the surfaces of different size teeth and gums. The two brush heads whose bristles contact the sides of the teeth are slanted at a predetermined angle.

Abstract: A safety razor which conforms to both concave and convex body surfaces and has a handle and a curved rotatable cartridge. Shaving blades are positioned on both sides of the curved cartridge, thus, both concave and convex accurate cutting edges are obtained in a single compact cartridge. The concave surface is used when shaving convex body surfaces. Rotating the cartridge 180 degrees exposes the convex cutting surface for shaving concave body surfaces. The cartridge is rotatably mounted to the handle and is held in either concave or convex shaving positions with detents. When the alternate shaving position is desired, the cartridge is rotated 180 degrees, either manually or remotely using a push button device within the handle, which is also disclosed. The correct angular relationship of the handle to the cutting surface of the cartridge is set and maintained for both concave and convex settings by means of the detents since the amount of rotation between the two shaving settings is 180 degrees.

Abstract: A powered toothbrush is provided with a pair of disc-like rotary brushes mounted for rotation about a axis generally perpendicular to the length of the brush. The rotary brushes are in axially spaced relationship and are provided with inwardly directed bristles. Between the rotary brushes, upper and lower linear brushes are mounted above and below the axis of rotation for linear reciprocating motion generally perpendicular to that axis. The upper brush has upwardly directed bristles, and the linear brushes are mounted to the rotary brushes so as to be brought into reciprocal, linear movement when the rotary brushes are reciprocated angularly.

Abstract: Rotary toothbrush utilizes a longitudinally extending hollow barrel having a fore-end and a rear-end. Longitudinally extending and reciprocatable strokearm mechanism is predominately located within the hollow barrel but includes a forward-portion always located forwardly of the barrel. A pair of transversely separated, upright rotary brushes are positioned wholly forwardly of the barrel and there eccentrically journal crankshafts carried by the strokearm mechanism forward-portion so that strokearm reciprocations cause the two brushes to move together in alternating angular directions. The strokearm mechanism forward-portion might be provided with auxiliary bristles for simultaneously brushing the dental occlusial surfaces as the rotary brushes treat the bucal and lingual surfaces.

Abstract: The portable reel has a non-rotatable spool extending longitudinally forwardly from a rearward mount and which surrounds a rotatable spindle extending along a lineal longitudinal-axis. An elongate radial arm is co-rotatably attached to the spindle, and the arm first-end is rigidly attached to a manually graspable tubular guide for flexible conduit carried by the spool. The tubular guide has an internally unencumbered and axially curved bore that preferably terminates as flared configuration terminal openings. As seen in top plan view and at the stage when the arm first-end is strictly vertically below the spindle, the tubular guide curved-axis and the spindle longitudinal-axis have an angular relationship within the range of about 5.degree. to 20.degree..

Abstract: A device for bending metal stock which utilizes a conventional die blade in conjunction with a die block formed from two bent metal plates. The plates have lower vertical portions which are parallel and space-apart to form a slot into which the die blade is inserted to bend the metal stock. The upper portions of the plates are bent outwardly to a horizontal coplanar position, forming a platform upon which the stock rests before bending.

Abstract: A center pivot irrigation system comprises a plurality of mobile towers spaced apart and aligned in a row with an irrigation pipe extending between and supported atop the towers. The row of aligned towers pivots about a mobile pivot tower located at a water supply. The mobile pivot tower comprises a vertically disposed frame mounted on a pair of wheels. The frame and one wheel are mounted to pivot about the other wheel, and anchoring structure restrains the other wheel from moving during pivoting of the frame and one wheel.

Abstract: Improved apparatus for flushing particulate matter from the pipeline of a center pivot irrigation system. The improved apparatus provides a length of downwardly extending pipe interposed in the pipeline in the immediate vicinity of or contiguous to the outermost mobile tower assembly of a plurality of such assemblies transporting the pipeline, permitting an operator standing on the ground to open the pipe during flushing. The downwardly extending pipe includes a restrictive opening for limiting the rate at which water is released from the pipeline during flushing.

Abstract: Improved apparatus for supporting the pipeline of a center pivot irrigation system between adjacent mobile tower assemblies adapted to transport the pipeline over uneven terrain. The improved apparatus includes means for coupling a triangularly-shaped truss to the pipeline and establishing a fulcrum at an intermediate point on the truss side members to equalize the forces applied to the truss side members as the pipeline is transported over uneven terrain.
