  • Patent number: 4850785
    Abstract: A machine for feeding a plurality of tubes (18) to a station at which articles in the tube, such as DIPs (10), are released into a discharge chute (46). The device includes a platen (56) which is inclined with respect to each of the two mutually-perpendicular horizontal axes. The tubes (18) are placed on the platen (56) The platen (56) has a wall (50) which occludes lower open ends of the tubes (18) when they are placed on the platen (56). The tubes (18) pass downwardly on the platen (56) along this wall (50). A second lower edge with respect to the other of the mutually-perpendicular horizontal axes, defines a releasing station, and when a tube (18) is in that station, its lower end is not occluded by the wall (50). Devices within the tube (18) are, thereby, permitted to pass outwardly into the discharge chute (46). Stops (80) are disposed proximate this lower edge of the platen (56) in order to arrest downward movement of the tubes (18) beyond the releasing station.

  • Patent number: 4846079
    Abstract: An apparatus for mating a structural element to a pair of frame members. The mating apparatus includes a stud carried by the element, a pin carried by each of the frame members, a brace positioned, during mating, so that inwardly turned portions formed at each lateral end of the brace engage a corresponding pin carried by the frame members. Structure is provided to urge the brace progressively closer to the structural element. As this urging occurs, the pins carried by the frame members are driven toward the structural element by the corresponding associated inwardly turned portions of the braces until the pins can be urged no farther. As this occurs, tightening of the frame members to the structural element occurs.

  • Patent number: 4818382
    Abstract: The invention of the present document is an improved disc singulator (10) for use in singulating and delivering to a test site (12) an integrated circuit device (14) to be tested by a tester mechanism. The singulator (10) includes structure to positively hold the device (14) within slots (64) formed in the periphery (52) of the disc (10) as it is rotated. A main body portion (16) of the device (14) is, thereby, held so that a plane defined by the main body (16) is oriented generally orthogonal to a plane defined by the disc (10). Additionally, the device (14) is held at an appropriate radial location with respect to the disc (14) so that, as the disc (10) rotates the device (14) carried thereby through a slit (40) in a printed circuit board (36) at the test site (12), contacts (26) of the device (14) will engage corresponding probes (38) at the test site (12).

  • Patent number: 4813573
    Abstract: A shuttle-actuated singulation apparatus (10) for use in handling integrated circuit devices (16). A shuttle (39), acting to isolate or singulate an individual integrated circuit device (16) for transfer to a test apparatus, is included. A shuttle assembly (30) is carried by a splined shaft (34) for rotational movement of shuttle (39) carried thereby. The assembly (30), additionally, is moved laterally by means of a drive cable (36). Rotation of a shuttle barrel (32) and associated upward pivoting of shuttle projectiles (42) carried by barrel (32) effects engagement of a bell crank (70) which, in turn, engages a belt drive mount (82) carrying a drive belt (80). The drive belt (80), thereafter, is engaged with an integrated circuit device (16) to impel the device (16) out of a track (12) in which it is received.

  • Patent number: 4776219
    Abstract: A pressure transducer is provided, in a preferred embodiment, with a pair of diaphragms (29, 28), each with a strain gauge, and with a rubber-like intermediate layer (33) therebetween. The layer (33) supports the first diaphragm (29) without interfering with its flexing up to a point where the layer (33) becomes non-resilient and transmits further flexing of the first diaphragm to the second diaphragm (28). The diameter of each diaphragm has to be about 2.75-3.75 times greater than that of its central flexing portion forming the bottom of a cavity (30) which, in the shown embodiment, is conical. The overall thickness of the diaphragm is preferably about 5 times greater than the thickness of the flexing portion to eliminate or at least substantially reduce the influence of parasitic stresses introduced by clamping forces holding the diaphragm in place.

  • Patent number: 4751060
    Abstract: The present invention is an improved extractor (10) for removing a liquid from a solid carrier medium in which the liquid is entrained. The extraction process is accomplished by utilizing both percolation and immersion removal methods. The extractor (10) includes a plurality of pools (12, 12') through which the solid entraining the liquid therein is moved in a direction counter-flow to that in which a solvent passes through the extractor (10). Percolation removal is effected at the overflow (48, 48') of each pool (12, 12') as solvent washes through the solids being processed. Immersion is effected at the lower end of a sloped floor (22, 22') of each pool (12, 12') where the solids are soaked in the solvent. A final percolation bath (14) can be provided as a last stage of the extractor (10).
