  • Patent number: 6918415
    Abstract: A lift as a personal tool used manually to lift portions of a fuel hose successively, equipped to slide along the fuel hose as a user walks erect as the user moves along the fuel hose progressively causing residual fuel in the fuel hose to drain out the hose distal end, away from the fuel truck. The lift includes a handle adapted for grasping by its user separated from a fuel hose support by a bar depending from the handle forming a C-shape with an open portion opposite the bar and a trough opposite the handle. A roller disposed to roll on the hose support has a radially extending flange on each roller end maintaining the fuel hose central on the roller. In use, the user walks in erect posture from the truck along the fuel hose with the lift hanging from the user's downwardly extending arm. As the hose leads to the ground and before the hose reaches the ground, the hose moves into the lift trough engaging the hose at a hose engagement level several inches above the ground.

  • Patent number: 6832536
    Abstract: A tube cutting machine comprises a tube secured in a chuck tightened against an outer tube wall and by a mandrel expanded within the tube against the tube inner wall opposite the chuck. A blade with a conical body side on the tube body side advances into the tube at the body side angle, eliminating longitudinal force against the tube body and accumulation of tube material on the blade body side. In alternative embodiments, either the tube or the blade can rotate. As the blade edge enters the tube wall, the blade end side, opposite the body side is also conical and pushes the tube cut portion longitudinally away from the tube body, causing the tube before the blade to neck under the longitudinal force imposed by the blade end side. The blade is reversed when the neck weakens and is unable support the tube cut portion but has not yet broken, referred to as the failure point. The blade is then withdrawn and the neck is snapped off. The failure point is detected by a rod urged transversely against the tube end.

  • Patent number: 6809671
    Abstract: A digital synthesizer generates an electrical digital carrier that is converted to analog and driven a probe coil to generate an electromagnetic wave propagated into a test material proximate the probe coil. A return electromagnetic wave generated by eddy currents in the material includes signatures of material defects modulated on the return carrier electromagnetic wave. The return wave is detected by one or more probe coils and amplified. A second amplifier is applied selectively amplifying the signal in segments such that each segment exploits the input range of the analog to digital converter. The signal is then converted from an analog signal to a digital signal and then digitally mixed with digital sine and cosine functions also generated by the digital synthesizer to yield sum and difference values. A gain scaling stage then trims the signal to overcome circuit imprecision such that the amplification in each respective segment is a power of two.

  • Patent number: 6802714
    Abstract: A tooth characterization guide includes several sets of tooth samples, each set representing a tooth different characteristic. The guide allows a dentist to compare guide samples in value and translucency with a patient's teeth to obtain an accurate characterization of a tooth prosthesis for the patient. From these tooth samples the dentist is able to first choose a suitable translucency, which is the most important and influential factor for true tooth replication from a first set of samples. The dentist then is able to choose a suitable brightness from a second set of samples. The dentist then is able to choose a suitable color and saturation from a third set of samples. The dental laboratory utilizing the guide selections can then objectively reproduce the observed tooth appearance.

  • Patent number: 6799611
    Abstract: An icing dispenser having an expandable elastic reservoir on the handle proximal end which when loaded expands a reservoir bladder under an elastic bias that tends to return the bladder to its unexpanded condition, therein uniformly impressing constant pressure on the icing within the reservoir. A reservoir neck extends from the bladder through a handle passageway to a decorator icing tip. A butterfly valve within the reservoir neck modulates an amount of icing flowing through the tip with butterfly ends angled parallel to the passageway and urged into the pliable neck at a preferred angle, slightly deforming the neck to effect a valve seal. The handle is adapted for operation in an operator's fingers as a writing instrument with icing extrusion modulated by a lever on the handle being adjusted relative to the handle by the fingers.

  • Patent number: 6761271
    Abstract: A wash bucket screen has a slanting platform supported on a frustum skirt. The platform has a plurality of holes interspersed between raised ridges on the platform running radially generally toward its perimeter as an aid in releasing water from a cloth squeezed against the platform. To effectively prevent backsplash from the bucket bottom back through the screen, the holes taper from a diameter sized to readily collect water on the platform top to a smaller hole diameter on the platform bottom. The skirt includes a flange on its distal end that engages the bucket wall. To accommodate a frustum bucket with changing wall diameter, the skirt flexes resiliently with the flange engaging the bucket wall and the skirt flexing inward as the screen is inserted in a bucket with decreasing diameter. To allow movement of the skirt, a plurality of slits extend vertically, opening at the skirt distal end, providing an effective splash shield between the skirt and the bucket wall.

  • Patent number: 6734669
    Abstract: A digital synthesizer generates an electrical digital carrier that drives probe coil to generate an electromagnetic wave propagated into a test material proximate the probe coil. A return electromagnetic wave generated by eddy currents in the material includes signatures of material defects modulated on the return carrier electromagnetic wave. The return wave is detected by one or more probe coils, amplified, converted from an analog signal to a digital signal and then digitally mixed with digital sine and cosine functions also generated by the digital synthesizer to yield sum and difference values, mathematically expressing various eddy current signals received by the probe in a complete set of orthogonal functions. A low pass filter then removes all but the difference values. A direct current reference component is subtracted from the mixed digital signal, which translates the signal to center about a zero axis for ease of display and analysis.

  • Patent number: 6734668
    Abstract: An eddy current probe comprising two solenoid coils wound around a common rectangular wafer base of high permeability material extending beyond the coils at wafer corners with the wafer becoming the solenoid core. Posts also of high permeability material depend from a wafer front at its corners with coils crossing orthogonally on the wafer. The coils are connected to alternating current to produce magnetic fields that have like magnetic poles at wafer corners diagonally opposed across the wafer, the coils switching in phase to alternate the magnetic field between posts at base diagonal corners. With the posts at the wafer base corners, the combined magnetic fields generated from the orthogonal coils conduct through the posts and emanate from post ends. The post ends have a curvature matching that of a material to be tested for better coupling the magnetic field into the material.

  • Patent number: 6708966
    Abstract: A C-clamp including a two-member back with a first member telescoping from a second member to a selective position where it is releasably secured. A securing mechanism, such as a cross pin or a ratchet a pawl in a rack on the first member, releasably secures the members together at a preferred position. In the preferred embodiment, the second member comprises a channel with the first member passing into the channel. Thus, the cross pin at the channel entry end engages one of a plurality of grooves in the top of the first member. To adjust the extent of the inner member from the outer member, it rotates out of the channel to separate the pin from the selective groove, allowing the inner and out members to adjust their relative position. Equivalently, the cross pin may remove from a groove of a nonrotating inner member.

  • Patent number: 6681572
    Abstract: A pair of articulated rods connect between a float and a pair of shafts through a one-way clutch on the respectively shafts. When a float rises an “up” connecting rod causes the “up” shaft to rotate as its clutch is engaged, and when the float falls, that clutch disengages, allowing that shaft to freewheel. Likewise when the float falls a “down” connecting rod causes the “down” clutch to engage and the “down” shaft to rotate, typically rotating opposite the rotation of the “up” shaft. When the float reverses and begins to rise again, the “down” clutch disengages and the “up” clutch reengages. A connecting rod hand member connected pivotably to the forearm at a wrist joint is adjustable in length. The wrist joint adjusts the effective length of the hand member to change the stroke of the machine to match wave amplitude through a computer-controlled pneumatic actuator.
