  • Patent number: 6990758
    Abstract: A heavy-duty scraping and rake attachment for excavator buckets for clearing brush-covered earth. The attachment is easily mountable to the bucket, thus avoiding the work and expense of removing the bucket from the arm. The scraper portion provides for offset toothed scrapers, a combination of toothed scraper and blade, and blade only use and is used in conjunction with a heavy-duty rake and power-operated thumb to grasp and remove the material rooted or scraped up from the earth by the scraper. The scraper portion and rake are included in a single unit, attachable and detachable from the excavator bucket. Scraper and blade attachments either detachably connected to the unit with bolts or permanently welded in place as desired.

  • Patent number: 6493967
    Abstract: The apparatus for attaching an accessory to an excavator is a device for attaching a grader blade, brush blade, compactor, or other accessory to the bucket of an excavator. The apparatus has a body to which the accessory is attached which has a pair of hooks which slide between adjacent pairs of teeth on an edge of the excavator bucket and a pair of chains attached to the rear of the bucket and tightened by load binders to retain the apparatus on the excavator bucket. The apparatus provides for pivoting the accessory laterally, and may optionally provide for tilting the accessory in a vertical plane.

  • Patent number: 6373269
    Abstract: An interface circuit board (20) for high test point density electronic testing equipment has a first thickness signal portion (20c) in which all the signal traces (20e) are routed and a second, thicker integrally formed transfer portion (20d) which transfers the signal traces to a respective test pad (20g) on the lower surface of the transfer portion. The transfer portion is made thicker to strengthen the board and is made integral with the first signal portion to eliminate the need for intermediate solder joints.

  • Patent number: 6040699
    Abstract: A mounting device (10) is shown particularly adapted for adjustably mounting vectorless test heads for circuit board components and the like to be tested for processing faults of component pin connections with traces of a circuit board in which the components are mounted. A U-shaped bracket (18) is lockably received on a rail (2) and has first and second projections (18d,18e) slidably received through a respective slot (16c,16d) of a leg (16) of a T-shaped member (12). The base leg (14) of the T-shaped member (12) is connected to one end of a pin member (24) which slides through a bore (18p) in one arm (18b) of U-shaped bracket (18) and is threadingly received in a threaded bore (18n) of the other arm (18a) of the U-shaped bracket (18). Rotational movement of the pin member (24) causes T-shaped member (12) to move in a Z direction to permit precise locating of a test head (30) mounted on the base leg (14).

  • Patent number: 5550481
    Abstract: A test fixture (10) for mounting electrical circuit boards (CB, CB') and placing a plurality of test locations of the circuit board in electrical engagement with respective probe test pins (16) of an array of such pins has a cam mechanism (22) mounted in an integrally formed modular frame (20) of an upper assembly (12). The upper assembly (12) is pivotably mounted on a lower base assembly (14) and latched thereto by a latch assembly (28). A circuit board to be tested is placed over an array of longitudinally depressable pins (16), the upper assembly (28) pivoted to a closed position and latched by latch mechanism (28). Handle (22k) attached to the cam assembly (22) is then rotated causing blocks (22f) to slide in rectilinear track (22e) of slide plate (22c) while translating rotary motion of the cams members (22g) to a vertical motion of a pusher plate (30) attached to the slide plates (22c).

  • Patent number: 5500606
    Abstract: A test fixture including top and bottom probe plates including double-ended pogo pins interfacing top and bottom interface printed circuit board (IPCBs), further including double-ended transfer pins to achieve a true wireless dual access test fixture. The top transfer pins electrically engage the bottom transfer pins after vacuum is applied to allow electrical interface with the top-side fixture without the use of wires. The top fixture mounts in a frame assembly through a parallel linkage keeping the top fixture parallel with the PCB under test. Guide pins mounted on the bottom probe plate are used to align a top plate holding the PCB and also to pre-align with bushings on the top fixture before vacuum is applied. When vacuum is applied, the top plate and top fixture move in a single longitudinal direction to electrically engage the test pins and test pads, preventing lateral movement which heretofore caused significant damage to the test pins and test pads.
