US Patent:

20040144190, Jul 29, 2004

Filed:

Jan 24, 2003

Appl. No.:

10/350440

Inventors:

Arthur Hall - Cicero IN, US

International Classification:

F16H003/097

US Classification:

074/331000

Abstract:

A power transmission includes a pair of input clutches, a plurality of ratio gear mechanisms, and an output shaft. The ratio gear mechanisms are selectively connected with respective countershafts to complete power flows between the transmission input and transmission output and one or the other of the input clutches. During a ratio upshift, a brake mechanism is connected with each of the input clutches to control the speed of the shafts connected therewith when the clutches are disengaged and an upshift condition is being preselected.

Appl. No.:

10/951421

Inventors:

Donald Klemen - Carmel IN, US
Arthur Hall - Cicero IN, US

International Classification:

F16H 37/02

US Classification:

475214000

Abstract:

A multi-speed power transmission includes a countershaft portion and a planetary gearset portion. The countershaft portion is controlled by synchronizer torque-transmitting mechanisms, and the planetary gearset portion is controlled by selectively engageable friction-type torque-transmitting mechanisms. The selective operation of these torque-transmitting mechanisms permit eight forward speed ratios and three reverse speed ratios.

Appl. No.:

7/723985

Inventors:

Arthur Hall - Cicero IN
Richard L. Wagner - Danville IN

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B60K 2300

US Classification:

403359

Abstract:

A drive connection between an engine and transmission has an internally splined flywheel drivingly connected to the engine and an externally splined driven member connected to the transmission and engaging the flywheel spline. A retainer ring includes a tab member which is disposed in a slot in the flywheel to maintain the spline connection. The tab has an area which is deformable after assembly to engage a recess formed in a wall of the slot to resist relative rotation between the retainer ring and the flywheel.

Appl. No.:

6/766873

Inventors:

Arthur B. Hall - LaPorte IN

Assignee:

TP Orthodontics, Inc. - Westville IN

International Classification:

A61C 700

US Classification:

433 3

Abstract:

A positioning jig for an edgewise bracket having a lingually disposed vertical slot or opening to position the bracket on a tooth when bonding the bracket to the tooth. The jig is disposable and mounted on the bracket to be handled as a unit during the bonding procedure and thereafter removable from the bracket once the bonding material has cured. Indicia is provided on the jig and the bracket to identify the tooth on which the bracket is to be mounted and the spacing of the archwire slot from the occlusal or incisal edge of the tooth.

US Classification:

433 14

Abstract:

A combination light wire and edgewise appliance for selectively treating a patient by the light wire technique or the edgewise technique, which includes a light wire bracket having a mesiodistally extending archwire slot and an occlusogingivally extending lock pin opening to which may be secured a round archwire by a lock pin and an edgewise module mountable on and securable to the bracket and having a mesiodistally extending and labiobuccally opening rectangular archwire slot, and ligating wings to which may be mounted a rectangular archwire and secured thereto by suitable ligatures.

Assignee:

TP Orthodontics, Inc. - Westville IL

International Classification:

B29C 3900
B29C 5908

US Classification:

264 80

Abstract:

A method of making an optically clear custom tooth positioning and retaining appliance in a flask or mold device having mold members from an elastomeric or resilient thermoplastic material with the capability of having optically clear transparentness, after the appliance has been trimmed and/or buff polished subsequent to molding thereof which causes the appliance to have a frosty or translucent appearance, which method includes subjecting the exterior surfaces of the appliance to a source of concentrated heat to cause surface melting which produces transparentness, cooling the appliance before, during and after heating as needed to preserve its integrity, and optionally utilizing the mold members from the flask or reproductions thereof in the archways of the appliance during heating thereof.

Appl. No.:

8/229032

Inventors:

Arthur Hall - Cicero IN

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B62D 5500
B60K 600

US Classification:

180 944

Abstract:

A dual-motor electric drive system is particularly suited for driving track-laying vehicles. The propulsion motors of the drive system are each individually selected to provide the speed and torque for selected portions of the operational requirements of the vehicle. The electric drive system utilizes a primary motor to provide the maximum speed requirements and a secondary motor to provide the high torque requirements for low speed operation. The primary and secondary propulsion motors are interconnected by a predetermined drive ratio so that the secondary motor provides torque until it attains a maximum predetermined speed whereupon it is disconnected from the primary motor.

International Classification:

B62D 1104

US Classification:

180 628

Abstract:

A dual-drive electric transmission operated by a generator that may be powered, for example, by an internal combustion engine. Left and right motor networks have a rotation rotor, the motor networks being powered by the generator. A speed control assembly independently effects rotation of the rotor in each motor network at selected speeds. Left and right combining differentials are associated with the respective left and right motor networks. Each combining differential has a sun gear, a ring gear and a plurality of planetary gears meshing with the sun and ring gears. An output carrier supports the planetary gears. The sun gear in each left and right combining differential is driven by the respective left and right motor network. The ring gears are conjoined for unitary rotation in order to provide a mechanical regenerative path between the combining differentials. A transfer differential interacts between the sun gears in the left and right combining differentials to serve as a mechanical regenerative path until the rotor in one of the motor networks reverse rotates under the load applied to the output carrier associated therewith, and a power transfer means thereafter effects electrical regeneration between said reversely rotating rotor and the rotor in the other motor network.
