Appl. No.:

09/720698

Inventors:

Alexander Savitski - Liberty Township, Delaware County OH
Robert A. Grimm - Columbus OH

Assignee:

International Classification:

B29C 6500

US Classification:

1563042, 1562722, 1562728, 1563043, 156158

Abstract:

A method for production of simultaneous lap and butt joints directs electromagnetic radiation ( ) through a radiation transmitting material ( ) to an absorbing material ( , and ) that absorbs radiation ( ) with the generation of heat. The heat provides sufficient molten material in interfaces ( , and ) to fuse and bond: 1) pipe ends ( ) to each other in a butt joint ( ), 2) pipe end portion ( ) to sleeve ( ) in a lap joint ( ), and 3) pipe end portion ( ) to sleeve ( ) in a lap joint ( ). Use of a sufficiently clear material for sleeve ( ) allows visual inspection of joints ( , and ). Butt joint ( ) can be formed by conductive heating without absorbing material ( ) to provide a smooth interior bore useful for transporting high purity fluids without risk of absorbent contamination or debris and organism collection in gaps found in previous joining techniques.

156/157000, 156/272200, 156/304300

Abstract:

A method for production of simultaneous lap and butt joints directs electromagnetic radiation () through a radiation transmitting material coupling () having an absorbing material () formed as a portion of coupling () that absorbs radiation () with the generation of heat. The heat provides sufficient molten material in interfaces (and ) to fuse and bond: 1) pipe ends () to each other in a butt joint (), 2) pipe end portion () to sleeve () in a lap joint (), and 3) pipe end portion () to sleeve () in a lap joint (). A coupling () is preformed with integral or surface applied radiation absorbing material () to provide rapid joint assembly and consistent weld production.

US Classification:

548347

Abstract:

Method for exhaustively alkylating the amine content of an imidazoline product prepared from a higher fatty acid and a dialkylene triamine wherein the protonated species formed in the course of the alkylation reaction are repeatedly neutralized, followed in each instance by reaction with an essentially equivalent amount of the alkylating agent based on the free amine present until the starting amine content of said product is predominantly converted to quaternary ammonium derivatives.

International Classification:

H05B 610

US Classification:

2191043

Abstract:

Induction heating of thermoplastic composite materials is accomplished to form a continuous bonded joint. A zone of optimum heating can be created by an induction heating coil mounted within and adjacent to the drum of a hollow circular roller of non-conductive material (i. e. , transparent to the RF field) so that an induction heating field can be created and localized to create a zone of optimum heating at the joint area of the material to be bonded. Simultaneously pressure to that area can be applied by the circular roller. In a preferred form, the roller is semi-rigid to permit spreading of the contact surface with the joint area to avoid absolute contact line loading. A hand held induction heating unit with a finger operable power switch can be moved in a back and forth manner over the joint to apply heat when the switch is turned on and effect consolidation when the switch is turned off. Using the techniques of the invention, one can fuse two contacting members which are comprised of filamentary reinforced composite materials in which the matrix resin at the joint interface is a member of the thermoplastic family of polymers. The invention concentrates radio frequency (RF) energy at the joint interface which heats the surrounding layers and simultaneously provides for the application of a controlled force normal to the mid-plane of the joint to retain compaction of the laminates which would normally be relieved in a hot unrestrained condition.

International Classification:

B23K 1302

US Classification:

219765

Abstract:

A process for obtaining long, continuous, thermoplastic welds on large structures. A series of tabs are used in pairs and especially in alternating, overlapping pairs to obtain resistance heating of a strip material placed in the bond line. The resistance of the tabs is less than that of the strip material. Conducting braid-tubes afford continuous welding when the bond line is curved. Alternatively, an electromagnetic field is used to take advantage of the induction heating. A wide susceptor is used to weld a current conducting substrate while avoiding bulk heating of the substrate. The unexpected property of current-conducting braid-tube susceptors, in which induction heating takes place at the center rather than at the edges of a flattened braid-tube susceptor, is used to obtain long continuous curved welds.
