Appl. No.:

10/715760

Inventors:

Gary Karr - Westerville OH, US
David Cyphert - Canal Winchester OH, US

International Classification:

B29C047/20

US Classification:

425325000, 425380000

Abstract:

Die apparatus configured for forming corrugated pipe from thermoplastic material in association with transported wall mold sets defining a wall forming tunnel. The apparatus employs two homogenizer stations, a first at its entrance for providing homogenized material to an outer wall delivery channel extending to an outer wall extrusion nozzle. Plastic material is delivered under pressure along a heated internally disposed extender pipe to a liner homogenizer stage located downstream and feeding a liner extrusion nozzle. An access region is made available between the outer wall extrusion nozzle and the liner extrusion nozzle.

425325000, 425336000, 425539000

Abstract:

Carriage assembly mounted molds are paired along a production system axis at a receiving region. Each carriage assembly is configured with an axially inwardly depending threaded connector nut configured to engage a translational screw moving the mold sets in registry about an extrusion die to establish a dynamic forming tunnel. Each mold of a mold set is configured having an internal mold cavity with mold crests spaced apart to define a sequence of vacuum support regions. A sequence of annular insert components are positioned over the vacuum support regions to form mold cavities and to define vacuum cavities.

International Classification:

B29C 47/20

US Classification:

425326100

Abstract:

System and apparatus for carrying out a thermoplastic material molding process wherein mutually abutting carriage conveyed clamshell molds are driven along a single track locus having vertically disposed tunnel forming and return region. Thermoplastic material is expressed vertically downwardly from a die nozzle located above the forming tunnel entrance elevation and with a diameter corresponding with but slightly less than the maximum diametric extent of a mold cavity within the mold sequence. Where a given mold cavity portion exhibits a minimum or zero cross dimension, the mold cavity is structured having an adjacent accommodation mold cavity portion of greater cross dimension.

International Classification:

B41J 312

US Classification:

400121

Abstract:

Marking apparatus and method is described wherein an array of marker pins are carried by translational assembly which, in turn, is driven from stepper motors which perform in conjunction with high helix lead angle lead screws. Solenoid actuated pneumatic valves are employed to actuate the marker pins within an array thereof and the entire assemblage of motors, valves, translational mechanism, and control features are retained within a compact housing structure. The control system and associated translational mechanism is capable of driving the marker head assembly in matrix, raster, and continuous modes of operation. Speed of marking is enhanced through the employment of a masking procedure wherein the translational mechanism drives the marker head assembly only to locations where active character forming pixels are present.

Appl. No.:

7/497507

Inventors:

David L. Cyphert - Canal Winchester OH
John A. Robertson - Chillicothe OH

Assignee:

Telesis Controls Corporation - Chillicothe OH

International Classification:

B41J 207

US Classification:

346140R

Abstract:

A linear array of solenoid actuated marker valve assemblies is contained in a housing configured as a manifold which carries marker fluid as well as nebulizing air supplies and a solvent distributing valve for use in clearing the air passages. All valve assemblies are accessible from the front surface of the device for ease of maintenance and are assembled in a manner assuring uniform and consistent valve stem travel advantageously eliminating the need for valve stem travel adjustment. The control system utilized with the valve assemblies provides both for an enhanced current input rate to the windings of the solenoid driven components, as well as an efficient and effective turn-off clamping procedure. This form of actuation of the solenoids achieves dynamically efficient and rapid turn-off and turn-on to the extent that the size of dots formed by the assembly can be provided having a broader range of diameters and these diameters can be adjusted remotely by a simple impedance variation. The features of the invention permit the application of characters at substantially enhanced production line speeds.

Inventors:

David L. Cyphert - Canal Winchester OH

Assignee:

Telesis Marking Systems, Inc. - Circleville OH

International Classification:

B41J 302

US Classification:

40012401

Abstract:

Marking apparatus for moving a marking head to coordinate positions utilizing two fixed stepper motors performing in conjunction with a cable and pulley drive system. The dynamics of pneumatically driven marrker pins within marker heads are accommodated for by a topology which includes a marker support base which, in turn, is supported in force transfer relationship with an air bearing which rides over a fiat platen surface. Improved marker head structure is developed utilizing a polyetherimide material and a design providing the introduction of return air into a two-component piston chamber at a location above a seating surface.

International Classification:

B23K 20/10
B23K 20/00
B23K 37/02

Abstract:

An ultrasonic welding apparatus joins metal pieces, such as wires, which are placed in a weldment zone where the metal pieces are subjected to pressure through a compressive height anvil and an adjustable width anvil, and intimate contact is made with a sonotrode of an ultrasonic stack. A first electric motor actuates movement of the height anvil to develop a compressive force for ultrasonic welding of the metal pieces. A second electric motor can position the width anvil before and during welding. A sensor, such as a load cell, measures the compressive force developed. The sensor directly can measure the load on the height anvil independent of the ultrasonic stack. A software algorithm can compensate for deflection of the load cell sensor and lost motion in the first electric motor actuating movement.

International Classification:

B23K 20/10
H01R 43/02

Abstract:

An ultrasonic welding assembly joins bare ends of an insulated wire bundle to a wire terminal in a weldment zone by intimate contact with a sonotrode of an ultrasonic stack. A door allows the operator to place the terminal into the nest within the weldment zone. One operator hand holds the wire bundle while one contacts an external sensor. A pair of terminal clamps extend inwardly and down to secure the terminal and create a taller capture area for the loose bare wire ends. A pair of clamp finger assemblies reversibly extend towards the insulated wires away from the weldment zone for securing the wires. A wire gatherer descends upon and captures all of the wire bare ends and secures them until the horn descends, captures, and holds the wire ends in place, then extends away from the weldment zone for ultrasonic welding to commence.
