Appl. No.:

13/625109

Inventors:

Michael R. Madson - Wrentham MA, US
Nicholas M. Nardacci - Bristol RI, US
David P. Hunt - Taunton MA, US

Assignee:

ACUSHNET COMPANY - Fairhaven MA

International Classification:

A63B 37/14
A63B 37/12

US Classification:

473379, 473378, 473384, 473381, 473382, 473380

Abstract:

The present invention is directed to a golf ball comprising of non-concentric arcs defining a non-planar parting line on its spherical surface resulting in having a large size disparity between dimples in one hemisphere and adjacent dimples from the opposing hemisphere. The parting line is produced by a pair of adjacent dimples, wherein D indicates dimples and N indicates dimples from the Northern hemisphere and those from the Southern hemisphere are indicated by S. A large disparity may be created, if the following condition is satisfied:

International Classification:

A61B 1732

US Classification:

606169

Abstract:

The present invention describes ultrasonic surgical instruments that include a mechanism for clamping tissue against an ultrasonic blade, including an arrangement for detachably mounting a clamp arm to the instrument. The ultrasonic surgical instrument comprises a waveguide adapted to be acoustically coupled to an ultrasonic transducer, and to transmit ultrasonic energy to an end-effector located at the distal end of the waveguide. A support tube extends from a handle assembly and surrounds at least a portion of the waveguide, terminating proximal to the end-effector. A clamp arm is detachably mounted to the distal end of the support tube. An actuation element is operatively coupled to the clamp arm. The ultrasonic surgical instrument may also include a clamp arm release. The actuation element comprises a first range of motion and a second range of motion, whereby moving the clamp arm release from a second position to a first position increases allowable motion of the actuation element from the second range of motion to the first range of motion, thereby facilitating release of the clamp arm from the support tube.

Assignee:

Acushnet Company - Fairhaven MA

International Classification:

A63B 37/00

Abstract:

The present invention is directed to a golf ball having a non-planar parting line about non-circular dimples on its spherical surface. The parting line comprises non-concentric arcs having straight connecting line segments between the arcs. Each arc maintains a tangency with its connecting lines and a relief distance greater than or equal to 0.003 inches when measured from an average non-circular dimple diameter to one of the non-concentric arcs and an absolute relief distance of at least 0.001 inches when measured from all points on the non-circular dimple perimeter to one of the non-concentric arcs. The sum of the lengths of the non-concentric arcs relates to the sum of the straight connecting line segments according to the equation:
