Development of an ultrasonic clutch
IEEE Symposium on Ultrasonics, 2003, 2003In the present paper, a newly developed ultrasonic clutch is proposed. The ultrasonic clutch can solve problems of conventional passive elements, such as time delay, instability, and large size, by using unique characteristics of ultrasonic motor, as fast response, silent motion, and non-magnetic feature.

Dual Clutch Transmission With Dry Clutch and Electro-Mechanical Actuation
ATZautotechnology, 2010The existing PowerShift transmission portfolio by Getrag with wet dual clutch and electronically controlled hydraulic actuation is expanded by a new version with dual dry clutch and electro-mechanical actuation. The range of applications sums up front-wheel drive, all-wheel drive, inline drive and longitudinal transaxle but now the new small ...

Transactions of the American Institute of Electrical Engineers, 1948
A new type of magnetic fluid and several classes of new devices utilizing this fluid have been developed at the National Bureau of Standards. One application of this fluid has been in electromagnetic clutches, but the electro-magnetically controlled mixture offers promise for other uses also.

Development of the Electrostatic Clutch
IBM Journal of Research and Development, 1957A brief historical review of the electrostatic clutch operating on the Johnsen-Rahbek effect is presented. Mechanical design of a clutch, special lubrication, and the fabrication of electronically conductive clutch facing material are described. A high-speed, high torque-to-inertia ratio test model with bi-directional shaft control is described.

Paper 1. Friction Clutches and Clutch Control Mechanisms
Proceedings of the Institution of Mechanical Engineers, Conference Proceedings, 1969Part 1 of this paper states the basic requirements of clutches and then discusses the various factors which must be considered in the initial stages of clutch design and specification for particular applications. The differing types of clutches used over a wide range of operating conditions are described and changes likely to be seen in future designs

Clutch is the title of the creative portion of my thesis as well as the name of my theory 'clutch' which I outline in the preface section. The purpose of the clutch theory is to recognize modes of inspiration in the body, heart and mind so that the poet can consciously move beyond passive receptivity to engage inspiration more fully.

Abstract This chapter considers clutch size, one of the most obvious and easily measured components of fitness. We determine the selection gradient on this univariate phenotypic trait (Arnold and Wade 1984b), and consider its ecological and evolutionary constraints and consequences.
