Abstract: A tube cutter mechanism supports an arm from which a tube supporting anvil extends, the anvil being aligned with the tube cutter mechanism for cutting the supoorted tube. During cutting, an axial force is imposed on the tube and anvil. The arm is formed such that it bends in response to the force, storing energy such that rotation of the tube occurs for more than one revolution of the tube without advancing the cutter wheel. The device is formed of molded glass fiber reinforce nylon, preferably ZYTEL. In a second embodiment, the arm does not bend and the anvil is constructed so as to bend relative to the arm in response to the axial cutting force permitting rotation of the tube during cutting beyond a single revolution without advancing the cutter wheel. The anvil advantageously does not have a cutter wheel for burnishing the tube to remove oxides during cutting.

Abstract: A rubber-metal bushing includes a seamless inner metal DOM tube surrounded by an elastomer cylinder. A flanged ferrule is press fit into one or both ends of the tube so that the flange engages an end portion of the cylinder. The bushing is cost reduced by replacing the DOM tube with a seamed tube formed from flat stock. An adhesive at the tube-ferrule interface maintains the two elements together.

Abstract: There is provided an improved coated composite article and an improved process for making the article. A cloth-like flexible preform is brazed to a metallic substrate to make the article. The article is then subjected to a uniform high pressure and temperature for sufficient time to remove porosity in the coating. The result is a fully dense coating, which is metallurgically bonded to the substrate without any porosity, which has improved physical properties, and which is capable of being polished to a surface finish of at least 4 RMS.

Abstract: An improved flaring tool includes the usual plurality of expandable die blocks retained by a U-shaped frame. A clamping screw is treaded through a clamp block which is rotatably mounted between the legs of the frame at its open end. The screw is movable toward and away from the die blocks to clamp or unclamp tubing between adjacent die blocks. A conical flaring tip is movable against the end of a clamped tubing for flaring same. The clamp block's axis of rotation is perpendicular to the direction of movement of the die blocks and the screw. The improvement comprises a facility which locks the clamp block against rotation when the screw is aligned with the die block and their direction of movement. The locking facility prevents unintentional rotation of the clamp block as the screw is rotated to clamp or unclamp the tubing, but may be manually overcome to intentionally rotate the clamp block.

Abstract: The wear resistance of hardface coatings formed on a metal substrate using cloth-like flexible preforms, by substituting two or more thinner preforms for the single layer preform heretofore employed.

Abstract: A bushing assembly for use with an associated torque rod comprises a bar pin, an elastomeric bushing, and an outer sleeve. The bar pin has a middle section which is generally rounded but which features a flat portion between 30% and 40% of the axial length of the middle section. The elastomeric bushing bonded to the bar pin is compressively received within the outer sleeve so that the total height is reduced by approximately 10%. The edges of the outer sleeve are curled inwardly toward a longitudinal axis of the assembly.

Abstract: A vibration damping device of the bushing-type includes a rigid outer housing and a rigid inner member, having a first side and a second side, which is substantially enclosed by the outer housing. A first vibration absorbing resilient body is interposed between the first side of the inner member and the outer housing. The first body is made of an elastomeric material having a first spring rate. A second vibration absorbing resilient body is interposed between the second side of the inner member and the outer housing. The second body is made of an elastomeric material having a second spring rate which is different from the first spring rate such that a deflection of the rigid inner member toward one of the first and second bodies will be resisted more strongly than a deflection of the rigid inner member toward the other of the first and second bodies. A first fluid chamber is defined in the second body and a second fluid chamber is defined between the second body and the outer housing.

Abstract: A flareless fitting includes a coupling body, a coupling nut and a ferrule. A tube is inserted so that it may extend axially inwardly a variable insertion length beyond the ferrule, through the length of a counterbore which is slip fit about the tube. Tightening of the coupling nut and the tapered arrangement causes the ferrule to be sealed between the tube outer wall and the internal cylindrical surface of the coupling body. Specifically, a single tube fitting system is provided which offers substantial tube penetration, or shallow tube penetration, without using two different kinds of fittings.

Abstract: An elastomeric clamp for securing an associated tubular member to another object and for isolating and dampening vibration comprises upper and lower elastomeric portions. The upper and lower elastomeric portions are joined at one end by an elastomeric hinge and near the other end by a closure means. An associated tubular member is compressively received within the opposing faces of the upper and lower elastomeric portions. The compressive force provided by the closure means deforms the elastomeric upper and lower portions about the tubular member, providing improved vibration isolation through the elastomeric nature of the upper and lower portions and hinge.

Abstract: A self powered vacuum evacuation device adapted for medical applications employing cylinderical body with piston member which is instantly energizable to a preselected variable vacuum level by using locking members and having automatic flow control valve system so that the device can be continuously cycled in operation without connecting and disconnecting to a source of fluid and drainage reservoir.

Abstract: A ball joint construction having a ball-stud member with a ball portion and a shank portion and an open-ended socket member in which the ball portion is contained. An elastomeric covering is permanently bonded to the ball stud and then deformed for inserting in the socket thereby resiliently interconnecting the socket and ball members. The socket member is provided with an inner wall portion with an outwardly tapered portion toward the bottom end of the socket.

Abstract: A quarter-turn, on-off plug valve having a valve body provided with a recess opening through a first portion of the body and closed at the opposite end by an integral portion of the body. A pair of stops are provided on a stem portion of the plug for accurately limiting the rotation of the plug to the 90.degree. different open and closed positions of the valve. The stops are defined by flat surfaces engaging a cylindrical retaining pin extending chordally through an upstanding annular wall portion of the body so as to provide improved accurate positioning of the plug in the open and closed positions of the valve.

Abstract: A bushing for rotatably supporting a bar-shaped suspension link comprises an elastomeric body having a central axis and including an axial bore adapted to receive the suspension link therethrough. The bore includes a circumferential surface having projected surface portions and recessed surface portions, the projected surface portions projecting radially inwardly to provide radial clearance between the suspension link and the recessed surface portions. Preferably, the projected surface portions include a plurality of first and second ridges projecting radially inwardly. The first ridges are substantially parallel to the central axis of the elastomeric body and intersect the second ridges at substantially right angles to define therebetween the recessed surface portions. The preferred embodiment of the bushing of this invention further comprises a double-knit fabric liner covering the circumferential surface of the bore of the body.

Abstract: A redundant seal arrangement employs first and second face-type seal assemblies for sealing between a housing and rotary member. A drain passage communicates with an intermediate area disposed between the first and second seal assemblies. During normal operation, minute amounts of fluid migrate past the first seal assembly and communicate with the passage to the drain. Alternatively, if the first seal assembly fails, a drain valve closes or a restriction orifice is used so that the intermediate area is raised to essentially the working pressure and the second seal assembly seals against further migration of the working fluid.

Abstract: A vibration bushing damping device includes an inner member and an outer member which is axially paralleled to the inner member and which encloses a substantial section of the inner member. A vibration absorbing resilient body is interposed between the inner and outer members. The body includes a first fluid holding chamber. A second fluid holding chamber is defined between the resilient body and the outer member. The second fluid chamber communicates with the first fluid chamber through a first fluid passageway. A rigid body is movably mounted in the first fluid passageway for controlling fluid flow through the first passageway to a varying extent depending on the position of the rigid body. A second fluid flow path is also provided for the fluid in the first fluid chamber.
