Abstract: A clamping device has a rotatably mounted clamping shaft (2), a clamping element (1), and a control mechanism (3). The clamping shaft (2) is formed from an inner shaft (2.1) and an outer shaft (2.2) that receives the inner shaft (2.1). The outer shaft is connected to the control mechanism (3) to pivot the clamping shaft (2), via a lever arm (5). The inner shaft (2.1) is rotationally connected conjointly to the clamping element (1). The inner shaft (2.1) is fixed in position relative to the outer shaft (2.2) by an adjustment element (4) connected to the inner shaft (2.1).

Abstract: A mechanical device for displacing jaws of a spring biased clamp includes a housing for receiving handles of the spring biased clamp. The housing has a platform moveable toward and away from a wall to move the handles of the clamp toward and away from one another, to move the jaws of the clamp away from and toward one another, respectively. A control member activates and deactivates a force applying member operationally connected to the platform, wherein activating the force applying member moves the platform toward the wall and deactivating the force applying member moves the platform away from the wall of the housing. The device is used to apply clamps to marginal edge portions of a stack of two one or more sheets to provide a clamped subassembly. The clamped subassembly in one embodiment is laminated to provide an aircraft transparency.

Abstract: A clamp includes a body, a lead pin moveable relative to the body and an actuator supported by the body. The actuator is axially moveable between an extended position and a retracted position. The actuator includes a camshaft drivingly coupled to the lead pin. Axial movement of the camshaft causes the lead pin to rotate between a first positioned aligned with a first longitudinal axis and a second position aligned with a second longitudinal axis laterally offset from the first longitudinal axis.

Abstract: A device for holding, positioning or clamping, particularly for the holding, positioning or clamping of pieces of auto body work, comprises a housing 1 containing a movable device 3 displaceable in translation under the action of an actuator 5, and an arm 4 for gripping or holding. The movable device 3 and the rod 8 of the actuator 5 are connected by an adjustable length device. A connection member 12 is screw threaded at one end, to coact with a tapping 9 of the rod 8 of the actuator.

Abstract: A pneumatically actuated clamp and gripped including a clamp arm supported for movement about a pivot, the clamp arm including a workpiece engaging portion spaced from the pivot and a driving member that is reciprocally moveable between a retracted position and a clamping position. The clamp further includes a link connected to the driving member and connected to the clamp arm in spaced relation from the pivot so that movement of the driving member from the retracted position toward the clamping position causes movement of the workpiece engaging portion of the clamp arm toward the workpiece, the link including a spring portion, the spring portion limiting the clamp force applied by the clamp arm to the workpiece.

Abstract: A device for stretching a screen on a roller frame includes at least three torsion stations and a support structure. Each torsion station includes a torsion tool, for example, a wrench head, which can be attached to one end of one of the sides of the frame and torqued for the purpose of stretching the screen. Each torsion tool is attached to a shaft structure at a first pivot point. Each shaft structure is attached to the support structure at a second pivot point. Each shaft structure has a pneumatic or hydraulic cylinder positioned intermediately along its length for altering the length of the shaft structure between its first and second pivot points, thereby causing the wrench head to torque and rotate one of the rollers of the frame. A control panel allows the operator to activate all of the pneumatic cylinders simultaneously and with substantially equal forces, thereby resulting in a more rapidly and evenly stretched screen.

Abstract: A galvanically conductive explosive is formed by the admixture of a small proportion of precious metal-containing platelets to a binder. The resulting blend is combined with explosive granules to form a homogeneous mixture which, after press-forming, produces galvanically conductive bodies.

Abstract: Enclosed rotatable head power clamp has an adapter mounted on a base surface between a power cylinder and a clamp head with an actuating piston rod extending through the adapter guided by rollers in tracks formed in bifurcated hollow side plates completely enclosing the actuating linkage for a pivoted clamp arm. The clamp head connection to the adapter can be adjustable indexed to any of eight angular operative positions about the axis of the piston rod.

Abstract: Several embodiments of a power clamp are disclosed which enable one arm or a pair of arms to be actuated for linear or rotational movement over a selected range of motion, depending on the manner in which the arm or arms are connected to the power clamp. Several embodiments, in addition to permitting actuation of various arms through various ranges of motion, further enable the arm or arms to be rotated about a transverse axis to a desired angular position, thereby further enhancing the adaptability of the power clamp device.

Abstract: A processor clamp for a tree harvester. The tree engaging surface of a movable arm of the clamp is made up of two elements, a convex cam portion and a concave portion, to insure that all trees within the diameter range of the harvester will be clamped along a line either perpendicular to a downwardly angled, fixed tree engaging surface or tending to force the tree upward along the surface. The fixed tree engaging surface is adapted to penetrate a tree clamped thereon, but permits the tree to roll off into a bunk when the movable arm is released. The clamp assembly is easily removable from and attachable to the harvester to selectively use the harvester as a single tree machine or a multiple tree machine.

Abstract: An improved roll slitting machine of the type used to slit wide rolls of material into narrow width rolls or ribbons includes an air chuck having gripping jaws which are actuated through multiple fluid logic paths to grip the roll of material for rotation about a changeable stationary mandrel. One end of the mandrel is supported by the machine frame and the opposite end is supported for quick release in the chuck.
