    Abstract: A solid weight load testing system is disclosed for testing the load capacity of a crane. The apparatus includes a holder that includes a platform and a post, the post having upper and lower end portions and being structurally connective at its lower end portion to the platform. A plurality of weights are selectively placed upon the holder by a user in order to arrive at a selected capacity. Each weight has a central opening that is sized and shaped to fit the post as the weight is lowered to the platform. A pair of lifting eyes are provided on each plate, the lifting eyes being mounted to the periphery of a weight on a line that intersects the center of the weight opening. An attachment portion on the top of the post enables a connection to be perfected between the holder and a crane to be load tested.

  • Patent number: 6131437
    Abstract: A mechanical crush gauge has a housing defining a fixed diameter hole that olds a sample of deformable material and an indentor having a flat end and a spherically-shaped end opposite the flat end. The indentor has its flat end flush with the surface of the housing and its spherically-shaped end in tangential contact with the sample. The indentor is made from a material having a yield strength orders of magnitude greater than that of the sample. Energy absorbed by the flat end is converted into kinetic energy that forces the spherically-shaped end against the sample to form a spherical dent therein indicative of energy flux density. In use, the diameter of the spherical dent is measured and converted to an energy value indicative of energy absorbed by the sample per unit area of the flat end of the indentor.

  • Patent number: 6038915
    Abstract: Apparatus and methods whereby flexible walled containers may be automatically pressure tested at a pressure testing station for the purpose of determining the presence of defective containers. Detected defective containers may thereafter be transported to an ejector station and ejected physically from their respective supporting tray. The pressure testing station is provided with an array of pressure testing heads which are moveable reciprocally towards and away from the containers while supported in their tray. Each of the pressure testing heads thus makes sealing contact with the rim of an individual respective one of the containers supported in the tray. The ejector station is provided with an array of ejector assemblies equal in number to the number of containers supported on a tray and oriented at an angle relative to a vertical cross-machine plane.

  • Patent number: 6023968
    Abstract: A method and apparatus for determining resistance and pulsatility indices of a flow of material, such as the flow of blood in the human body. This may be implemented, for example, in a color flow module in an ultrasonic imaging system for display of the pulsatility or resistance index in two dimensions and in different colors to allow discrimination between veins and arteries and detection of pathologic elevation of vascular resistance in a clinical survey mode of the system. The resistance index is determined from the ratio of a unipolar variation estimate of a velocity of the flow material divided by a peak velocity. The variation estimate may be one of the following: a difference between a peak velocity of the flow of material and a second minimum (if unipolar) or negative (if bipolar) velocity of the flow of material, a standard deviation .rho.

  • Patent number: 5959200
    Abstract: A micromachined structure providing for independent vertical and lateral deflection sensing. The structure uses high aspect ratio ribs which bend much more easily in one direction than in other directions (i.e., have a predominant direction of compliance). One or more ribs are combined to form beams which also have one predominant direction of compliance. Two such beams are bonded end to end, and one end of the beam pair is bonded to a base. The beams are oriented orthogonally to one another such that they independently bend to vertical and lateral external forces. Further, three dimensional force sensing can be accomplished by adding a third beam. Sensors can independently sense the bending in each beam and thereby independently measure the dimensional components of bending forces applied to the free end of the structure. In the preferred embodiment, piezoresistive sensors are formed on the ribs comprising the beams. The piezoresistors can be made by ion-implantation, for example.

  • Patent number: 5959198
    Abstract: The invention concerns a method of testing the hardness of workpieces (22), wherein an impact body (20) is moved onto the workpiece (22) to be tested such that it impinges thereon (along a forward path) and rebounds thereof (along a return path). On both the return and the forward paths, a movement value of the impact body (20) is detected by a contactlessly operating device and a measure of the hardness of the workpiece (22) is obtained from the difference between the forward and return path movement values. The movement value is detected at at least two points on the forward path and at at least two points on the return path. Corresponding to each movement value detection point on the forward path is a point on the return path at a substantially similar distance from the point of impact.

  • Patent number: 5955680
    Abstract: A device for measuring the natural bending strength of a sheet material, and for measuring the bending strength of a creased or scored portion of the sheet material, and for dynamically analyzing such test results. The device has a rotatable clamp, a load sensor, a data processing unit, and a data displaying unit. The load sensor is positioned to directly contact the sheet material being held by the clamp. The clamp and sheet material can be rotated so that the sheet material presses against the load sensor, and the data processing unit will then determine the resistance force detected by the load sensor and will determine the amount of rotation associated with that force, and the resulting data are then processed, stored, and can be displayed as output data in a predetermined form.
