Abstract: A pin clamp for use in a manufacturing line. The clamp including a body and a pin arranged on one end thereof. The clamp having a hook arranged within the pin. A first torque arm is connected to the hook and contacts a spring. A second torque arm contacts the spring and a link member. The clamp is capable of holding workpieces at various load strengths and workpieces having a variety of thicknesses.

Abstract: A power clamp for use in a manufacturing environment. The power clamp including a base and an extruded body secured to the base. The power clamp also includes a cylinder having a rod secured to the body. A shaft is rotatably supported by the body of the clamp. The clamp also includes a bar connected to the shaft and a rotator pin engaged with the shaft. The clamp also includes a link member connected to the rotator pin on one end and to the rod on the opposite end.

Abstract: A hook unit for use with a clamp in a manufacturing environment. The hook unit includes a base and a sliding member arranged therein. A hook extends through the base and sliding member. The hook and sliding member form a barrier for the clamp.

Abstract: A hook pin unit for use in a manufacturing environment. The hook pin unit includes a pin having an orifice through a surface. A base having an orifice with the pin arranged within the orifice of the base. A hook arranged within the pin and moveable between a first and second position.

Abstract: An all plastic (preferably fluorocarbon) automotive hose has great strength relative to the light weight thereof. The hose is made of an inner layer which has a preferably circumferential grooves on an outer wall and an electrically conductive surface on an inner wall. An outer jacket is extruded over the outer wall with the jacket material filling all grooves to provide a mechanical interlocking between the inner layer and the jacket. The cross section of the grooves is selected on a basis of the amount of mechanical movement desired between the inner layer and jacket. Some grooves provide uniform flexibility, some provide progressively greater resistance to bending, and some provide a differential resistance to bending--more resistance in one direction than in another direction.
