A method and apparatus for a tracking door centering system. An apparatus may comprise an elongate member, a first centering track, and a second centering track. The elongate member may have a first end and a second end capable of being rotatably mounted to a door along an axis that may be substantially parallel to a horizontal centerline. The first centering track may be mounted on the first end. The second centering track may be mounted on the second end. The first centering track and the second centering track may be movable to reduce rotational movement of the door during movement of the door about a vertical centerline when a first follower is engaged in the first centering track and a second follower is engaged in the second centering track.

A hand cracker for nuts, particularly thick shelled macadamia nuts, the cracker having a receptacle with a bottom and a side wall for receiving a nut to be cracked with an off-center cracking shaft with wedge blades arranged circumferentially around the shaft and a crank device to rotate the shaft and wedge the nut between the wedge blades of the shaft and the wall of the receptacle wherein the nut is cracked by the force of the wedge action of the wedge blades.

A nut cracking machine constructed to crack nuts of different size in a continuous operation is provided, the machine having first and second disks that are spaced apart with opposed tapered faces forming a narrowing gap therebetween, the first disk being rotated on a first axis and the second disk being rotated together with the first disk on a second axis slightly skewed from the first axis such that the face of one disk is oblique to the face of the other disk and when rotated together, the gap between the faces of the disks has a wide sector and a narrow sector. The machine includes a feed mechanism to feed nuts of different size to the space between the disks where the space is widest, the nuts advancing between the tapered faces until the nuts are engaged by the disks and are then transported to where the gap narrows, the disks compressing the nuts therebetween and cracking the shells.

A snubber is disclosed for use on an airplane translating door hinge arm (13) comprising a hydraulic device (41) and a flow regulation system (40). The hinge arm (13) includes sprockets (25, 27) placed at the ends (15, 17) of the hinge arm (13). Roller chain pieces (31) rotate partially about the sprockets (25, 27). A pneumatic actuator (33) having a through-rod (37) and housing (35) is located on one side of the hinge arm (13). The actuator housing (35) is supported by a support member (23) integral with the hinge arm (13). The ends of the actuator through-rod (43) are each coupled to first ends of each of the roller chain pieces (31). The hydraulic device (41) comprising a housing (47), a through-rod (43), a piston 45, a first compartment (49), a second compartment (51), and hydraulic fluid, is also supported by the support member (23). The ends of the hydraulic device through-rod (43) are each coupled to second ends of each of the roller chain pieces (31). The hydraulic device (41) is located on the side of the hinge arm (13) opposite the side having the actuator (33).

A hinge arm (16) has opposite ends (18, 20) pivotably connected to an aircraft door (2) and a door frame (8). First and second sprockets (22, 26) are fixed to the door (2) and frame (8) adjacent to the ends (18, 20). A programming chain (30) extends around the sprockets (22, 26) and the arm (16). A linear motor (36) is mounted on the arm (16) in-line with the chain (30). When pressurized gas is supplied to the motor (36), it moves the chain (30) to open the door (2) and maintain it parallel to its closed position as it moves toward and into its fully open position. The door (2) may be opened manually without moving the motor piston (44) because the motor rod (52) slides freely through an axial opening (46) in the piston (44).

A nut shelling machine in which a rotary drive mechanism operates a rotary feed mechanism and a rotary shelling mechanism, the shelling mechanism having a frame with four shafts arranged in spaced, side by side, upper and lower pairs, the shafts having surface lobes and indentions for enlarging and contracting the effective space between the upper pair and lower pair of shaft for accepting and trapping a nut between the pair of upper shafts and lower shafts, where it is shelled by a shafting implement before the shell and nut passes between the pair of lower shafts.

An overcenter mechanism (10) includes a housing (12) and a first shaft (14) mounted on the housing. The first shaft has a first axis (34). A second shaft (20) is mounted on the housing and the second shaft has a second axis (41) that parallels the first axis. A lever (16) is attached to the first shaft, and the lever pivots about the first axis in response to a force (F. sub. op) applied to the lever. A cam (18) is attached to the first shaft, and the cam pivots about the first axis. The cam has a cam surface including a first surface portion (58) and a second surface portion (60). The first and second surface portions form a cusp (62) therebetween. A cam follower (21) has a cam follower surface, and the cam follower pivots about the second axis. A biasing member (26) urges the cam follower surface against the cam surface in pressure contact. The cam follower and the pressure contact cooperate with the cam to generate torque (. tau. sub.
