Abstract: A tray, on which IC elements to be tested are arranged at a pitch P1, is disposed at a first position, a performance board, which has a plurality of testing stations at a pitch P2, is disposed at a second position, and an IC chuck carrier is guided between the first and second positions by X-axis and Y-axis rails. The IC chuck carrier has a plurality of chuck heads arranged in a line and the pitch of arrangement of the chuck heads is selectively set, by a pitch switching device, to the pitch P1 or P2. The chuck heads are set to the pitch P1 on the tray and simultaneously chuck up therefrom a plurality of IC elements. Then, the chuck heads are brought to the second position, where the pitch of the chuck heads is switched to P2 and the IC chucked by the chuck heads are simultaneously attached to the plurality of testing stations.

Abstract: Sheets are stacked in a container substantially open at its front, and which has a pair of sidewalls and an upright back wall having a pair of edges each secured to a respective adjacent edge of the sidewalls. After a stack of sheets is formed within the container by depositing them through the open front of the container, the bottom of the stack or container is supported, and the supported stack and the container are lifted and moved from a first location to a second location. Because of the open front, the container can be slipped from around the stack to leave the stack standing at the second location free of the container.

Abstract: A cotton cart with a discharge control apparatus in the basket is provided. A tray-shaped member is mounted in the basket for movement between a retracted position and a discharge position. The member is supported by a system of links so that the member pivots about a moving pivot point. As a result, the leading edge of the member follows an eccentrically arced path which conforms substantially to the inner contour of the basket to facilitate evacuation of the basket. The member is operated by a hydraulic cylinder, thereby enabling the operator to manipulate the cotton bolls during the discharge procedure.

It comprises, at the lower part of the chassis (1), at least one support devices (7) adapted to come into contact with the frontal face (5) of the bin (4), preferably at its lower half, said one or more devices being controllable for being applied forcefully to the bin during at least part of its path of displacement, during the operation of the dumping device.

Abstract: A lift apparatus adapted for reliable, substantially maintenance-free operation in material transfer systems, including systems that are subject to considerable contamination. The lift apparatus includes an open top container, a support plate for normally supporting the container in upright position, and a ball screw drive for moving the support plate and container between a filling station in which material may be introduced into the container and a discharge station. The container is supported for relative pivotal movement with respect to the support plate, and a chain and sprocket arrangement is provided for automatically pivoting the container to a dumping position as it is raised into the discharge station and for returning the container to its normal upright position as it is lowered from the discharge station following dumping.

Abstract: A device is disclosed, which is useful for subdividing and diluting an accumulated amount of pirns in bulk, which comprises a chute positioned between a pirn container, and a conveyor belt. The conveyor belt is prearranged to transfer and meter a limited number of pirns. Along the chute, at least one barrier wall is provided, which can move along a vertical, or substantially vertical, direction, and is driven by a drive source, whose enabling is commanded by a level sensor located downstream the same barrier wall. A plurality of movable barrier walls, following each other, transversely prearranged along the chute relatively to the pirn falling motion, can be used. Each barrier wall is driven by a drive source, whose enabling is commanded by a level sensor located downstream of the barrier wall.

Abstract: An apparatus and method for transporting and unloading a container (10, 10A) carrying particulate lading which is removably mounted on a tiltable support frame (76, 76A) pivotally mounted on a highway trailer (54, 54A). At the unloading site, a portable throttle valve assembly (108, 108A) and flexible connecting hose (166, 166A) are connected to the container (10, 10A) and the container (10, 10A) is tilted by the support frame (76, 76A) to an angle above the angle of repose of the lading for gravity unloading of the lading from the container (10, 10A) in to a trailer mounted rotary valve (148, 148A) which forms an air lock over a subjacent pneumatic hopper structure (144, 144A) for pneumatic conveyance of the lading to a storage facility.

Abstract: A system for handling DIP devices packaged in elongated tubes having releasable closure means normally closing at least one end of the tubes to retain DIP devices therein, a head assembly for transferring tubes from an accumulator station to a DIP processing apparatus comprising a housing having an inlet and a discharge trackway section, a pair of drive rollers rotatably mounted adjacent the inlet end of the housing. The rollers are mounted for floating movement relative to one another in a direction generally transverse to the movement of tubes through the housing, closure removal and re-application mechanism downstream of the drive rollers, means for aligning the tube to ensure flow of DIP devices from the tube to the discharge trackway and tube position sensor means operable to activate mechanism for positioning the head assembly so that the discharge trackway section aligns with an inlet trackway of DIP processing apparatus.

Abstract: A transportable bin-type container having opposed side and end walls and opposed top and bottom walls, the container including a pair of outwardly extending pivot shafts extending from the opposed end walls to define a pivot axis. The container is adapted to be received on a truck bed, or the like, wherein a pair of spaced bearing support members are provided that extend upwardly from the truck bed in substantially parallel relationship, and that are spaced a distance slightly greater than the spacing between the end walls of the container. The bearing support members include an upper surface and an elongated, upwardly facing opening to receive one of the pivot shafts of the container, the opening including a pair of spaced, substantially parallel walls the outermost of which is longer than the innermost to define a transverse stop means for the pivot shafts when the container is being loaded on the truck bed.

Abstract: A trailer for towing by family saloon cars and the like has a wheeled frame (12) with a towing hitch (34) at the front. The frame has a respective ramp rail (22) at each side to enable a skip (14) to be drawn onto the frame, a support wheel (25) of the skip engaging on each rail. The skip can carry heavy bulk loads such as sand or bricks in the region of a ton which normal car trailers could not support. In addition, the mounting of the skip on the trailer frame by means of support wheels enables the skip to be pivoted in situ to tip out its load. Tipping, and mounting and demounting of the skip are effected using winch (16) supported on the frame near the towing hitch. The trailer also has a pivotable ramp (50) enabling the trailer to be used to carry heavy plant such as a cement mixer or roller.

Abstract: An open-topped container is constructed with a plurality of compartments, each having its own discharge opening and each having its own liner of the type that can be selectively rolled up or unrolled according to loading and unloading operations. Each liner is connected to its own biasing means which is effective to yield and lower the liner as the compartment is loaded and effective to recover to elevate the liner to facilitate unloading, all for the purpose of handling material, such as fruits and vegetables and the like, in such a way as to eliminate or at least minimize damage thereto.

Abstract: An apparatus for storing mixed cargo in which a plurality of containers each house therein a plurality of storage channels arranged in tiers and rows filling each container and located immovably with respect to each other. The storage channels lead away from a loading and unloading opening in one container end wall. Each channel has a smooth, low friction bottom extending in its longitudinal direction. Packages are loaded through the loading and unloading opening one in back of the other in series in each channel. The channels are loaded by pushing items of cargo in mutual contact into the channels and by tilting the container to allow sliding of the items of cargo in rows out of the channels.
