This book is a pamphlet for the public, intended to introduce them to a new product made by the Sperry Corporation: The gyrocompass. It is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical direction automatically. The use of a gyrocompass is one of the seven fundamental ways to determine the heading of a vehicle.

Ship Stabilizers: The Design and Operation in Correcting the Rolling of Ships presents the working principles and operation of various types of gyrocompasses and automatic pilots. This book discusses the fundamental principles of synchro systems and servomechanisms. Organized into 12 chapters, this book begins with an overview of the problem of the reduction of rolling. This text then explores the means of resisting rolling, which have been used or are still being used, including bilge keels, oscillating weights, anti-rolling tanks, gyroscopic stabilizers, and tilting fin systems. Other chapters consider the anti-rolling tanks that are divided into three types, including diversified tanks, free surface tanks, and U-tube tanks. This book discusses as well the small oscillations of a vessel in still water, which are simple harmonic in character. The final chapter deals with the stabilizing gear for smaller ships. This book is a valuable resource for marine engineers and naval architects.

Australia’s Submariners are a group with an extremely strong sense of identity that goes well beyond occupational comradeship or the esprit de corps of military life in peace or war. Since 1914, the unique skills, attitudes, values and demands of the work they do and the environment in which they do it have forged unparalleled camaraderie. A camaraderie that extends beyond nationality, embracing submariners past and present of every other nation. No one but submariners understand the experience of diving deep beneath the waves in technology filled tubes of steel, each submariner totally dependent on the other for a safe return to the surface. The ethos of Australia’s submariners is based upon these factors and remains strong even when they leave the sea and take up other occupations. Australia’s future submarines will certainly present challenges in terms of sophistication, technology and capability however the characteristics of our submariners evolved over previous generations will remain much the same; trained and equipped to meet the challenges; just as they have been met and surmounted so many times, in silence, over a century of service.
