Abstract: In a parallel motion finger probe, the parallel motion arm is rigidly connected to a shaft which is supported in a linear ball sleeve bearing, instead of by a parallel motion linkage as in prior finger probes. The parallel motion arm can be biassed in either of its two opposite directions of movement by a leaf spring, whose biassing force and direction can be adjusted by a control wheel having an eccentric groove co-operating with a pin on a spring control arm to which the spring is connected. The leaf spring also serves to prevent rotation of the parallel motion arm about the axis of the bearing. Displacement of the parallel motion arm is sensed by an inductive displacement transducer of the LVDT type.

Abstract: Disclosed is a recoil reducing mechanism for use in shotguns. The mechanism utilizes explosive gases from the shotgun barrel which are conveyed through gas passageways into a chamber within an attached cylinder. The cylinder is provided with a slidable piston which moves rearwardly under the pressure of the exploding gases. Gas pressure acting on a front plug of the cylinder creates a force which counteracts the recoil force of the shot shoulder. The mechanism also includes a compression spring which is rearward of the piston and between the piston and a breech plug installed in the breech end of the cylinder. The compression spring serves to return the piston into a battery position. The front end plug is provided with a resilient stop means which cushions the piston as it returns under the action of the compression spring. The invention also includes a method for converting over-under type double barrel shotguns or single barrel type combination shotguns to include the recoil reducing mechanism.

Abstract: The cutter box which houses a cutting cylinder on a harvester has an access opening in its top wall through which an abrasive, full-length sharpening stone may be alternately inserted and removed to engage and sharpen the peripherally located knives of the cylinder as the latter is rotated. Each time the stone is rocked down into the opening for a sharpening operation, it is indexed slightly further into the opening than during the previous operation in order to accommodate the slightly reduced diameter of the cylinder due to material which has been removed from the knives and the stone during the previous sharpening operation. A cover coupled with the stone is caused to move into closing relationship with the opening as the stone is rocked out of the same and, conversely, to pull away from and expose the opening as the stone is subsequently reinserted. All of the mechanical movements involved, including indexing of the stone, may be accomplished remotely through the use of an electric motor.

Abstract: A reciprocating platen automatically aligns and seats the carriers. Extending downwardly from the surface of the platen is a pair of spaced, conically shaped projections. As the platen is lowered, the inclined surface of each projection engages and cooperates with the edge of one of the circular finger-grip openings in the upper surface of the carrier. The carrier moves in a plane parallel to the platen surface until the base of each projection is received within a different one of the openings, thereby correcting any misalignment. Further movement of the platen causes the platen surface to exert a downward force on the carrier. This results in the container engaging openings being received over the closures of the respective containers. The platen is provided with recesses, each aligned with a different container engaging opening. The closures are received in the respective recesses to permit the platen to move to an extreme downward position.

Abstract: A stretch wrapping system including apparatus and process is disclosed in which rotation of a noncylindrical or off-centered load draws film web at a continually fluctuating speed from a film roll through a prestretching device to wrap the load. The prestretching device includes an upstream roller coupled to a braking device and a downstream roller coupled to a positive torque device. The speed of the downstream roller is proportional to the take-up speed of the web on the load and the feedback device continually senses the speed of both rollers and adjusts the braking device so that the speed ratio of the rollers produces a constant stretch of the film web above its yield point. The feedback device also continually senses the forces contributed by the braking device and the torque device and continually adjusts the torque device so that the force on the web between the downstream roller and the load is held constant at a level below the yield point of the web.
