Abstract: A handle attachment structure primarily designed for use for the gripping of opposite sides, but at least one side wall, of a cardboard or like penetrable material box of the type intended to carry computer paper or like material and including two leaves at least one of which is provided with supporting teeth on its inwardly facing surface thereof for the penetrating engagement of the side wall of the box. A handle means is movably attached to the leaves and is selectively positionable into and out of a coplanar position with the wall being gripped, the latter coplanar position defining a lifting position of the handle relative to the box and leaves.

Abstract: A vacuum holder which comprises a chuck provided with a recess facing a silicon wafer, a suction pipe for sucking air in the vicinity of the recess, and four separately-positioned holes penetrating the chuck in communication with the inner space of the recess.

Abstract: In a preferred embodiment of the invention, a depending pair of fingers may be caused to grip a component on an inside surface by spreading the fingers apart or to grip the outside surface of a component by closing the fingers upon the component, with the relative orientation of the gripping faces of the fingers depending upon sliding displacement of the tool posts supporting the fingers. The fingers are driven into positive engagement with the surface to be gripped, for both inside and outside gripping, via positive displacement and spreading of cam followers by a cam which, in turn, is displaced by a fluid cylinder. Alternatively, the fingers may be biased into engagement with the surface to be gripped, for both inside and outside gripping, with disengagement of the fingers being provided by positive displacement and spreading of the followers by the cam.

Abstract: A vacuum lifting arrangement for flat workpieces, such as wooden boards, wooden beams and the like, includes a vertically and horizontally movable housing bounding a suction chamber having a downwardly open suction side. A valve insert is accommodated in the suction chamber and is preferably removably mounted on the housing. A closing plate is hingedly mounted on the housing for pivoting into an out of a closing position in which it sealingly covers the downwardly open suction side of the suction chamber and the valve insert. An elastic sealing element in the form of a foamed mat having suction apertures is mounted on the closing plate, and is operative for sealingly contacting the workpieces to be lifted.

Abstract: A double-retention redundant pull pin release system is disclosed. The system responds to a single pull during an intentional release operation. A spiral-threaded main pin is seated in a mating bore in a housing, which main pin has a flange fastened thereon at the part of the main pin which is exterior to the housing. Accidental release tends to rotate the main pin. A secondary pin passes through a slightly oversized opening in the flange and is seated in a second bore in the housing. The pins counteract against one another to prevent accidental release. A frictional lock is shared between the main and secondary pins to enhance further locking of the system. The secondary pin, in response to a first pull, is fully retracted from its bore and flange hole. Thereafter the pull causes the main pin to rotate free of the housing to release, for example, a parachute mechanism.

Abstract: A principal or main conveyer cooperates with branch conveyers in that diverting wheels are provided for pivoting to the left or right as well as for lowering and raising, for obtaining selectivity of diverting.

Abstract: A locking device is described for use in selectively locking a plurality of pivotable members at selected operative positions about a central axis. The device includes means for mounting the members for pivotal motion about axes that may be substantially parallel and spaced outwardly from a central axis of a support. The device also mounts the members for axial motion along the axes between locking and unlocking positions. An axially displaceable spool is spring biased on the support to normally urge the members axially toward the locking position. In the locking positions, locking surfaces on the members mate with complimentary surfaces on the support to prevent pivotal motion of the members about the individual member axes. The spool is selectively movable on the support to lock itself and the members in this axial orientation. The spool is also selectively retractable to enable axial separation of the locking surfaces. The unlocked members are individually pivotable to folded, inoperative positions.

Abstract: A new wood stove and fireplace residue removal tool and temporary storage device having a shovel member nestable into a tubular structure which is closed at one end for the temporary disposition of ashes and other waste products from a fireplace. The device includes a shocker, for urging the ashes rearwardly from the shovel component to the storage component. An optional poker for stacking the fire may be removably secured to the device for ready access by the user. A handle to enhance portability especially when the device is warm may be disposed upon at least the storage component. The storage component can also have a one way flap, to prevent material already disposed within the storage compartment from escaping when the device is angularly tipped for the collection of additional waste materials.

A belt (20) is fixed to the cradle (10) and is suitable for being worn by the user to hold the cradle (10) substantially at waist height and on the hip of the user.

Abstract: A swivel connector includes a ring (1) which is assembleable into a slot (5) in a hoist member (2), with the slot having an open end forming an enlarged bifurcated recess portion (8). The ring and hoist are assembled to an annular housing (9) and a first nut (14) is positioned for sliding movement and relative rotation within the housing and is threaded onto the slotted end of the hoist member. A plug (16) is positioned within the bifurcated hoist slot recess end and a second nut (17) having a threaded axial opening is secured within the housing. A threaded shaft (22) is provided and which is threadably disposed within the second nut opening and in relatively loose engagement with the plug. The shaft extends outwardly for securement to the load or the like. During swiveling use, the ring (1), hoist (2), plug (22) and first nut (14) turn together, with the other elements remaining fixed.

Abstract: A device for hand-carrying articles includes a metal carrying handle and an elongated carrying strap. The handle has a pair of spaced apart, elongated side sections which extend along and are positioned on opposite sides of handle axis. The side sections are interconnected at their upper ends by a handgrip portion which extends transversely to the axis, at their lower ends by a lower crossbar which has an elongated slot formed therethrough, and at longitudinally intermediate portions thereof by a central crossbar to which is anchored an end portion of the carrying strap. To carry an article, the strap is looped around the article to define a carrying loop portion of the strap. The free end of the strap is then passed over the lower handle crossbar and then back through the crossbar slot to define in the strap a strap connecting loop portion. When the handle is lifted, the connecting loop portion is frictionally locked to the lower crossbar to prevent enlargement of the strap carrying loop.

Abstract: An electronic force-detecting robot gripper for gripping objects and attaching to an external robot arm is disclosed. The gripper comprises motor apparatus, gripper jaws, and electrical circuits for driving the gripper motor and sensing the amount of force applied by the jaws. The force applied by the jaws is proportional to a threshold value of the motor current. When the motor current exceeds the threshold value, the electrical circuits supply a feedback signal to the electrical control circuit which, in turn, stops the gripper motor.
