The final achievement of Mr. Brown's long and interesting mechanical career runs a close second in importance to his development of the universal milling machine.

That achievement was his creation of the universal grinding machine, which made its appearance in 1876 at the Philadelphia Centennial Exposition.

This machine, like its milling counterpart, was the antecedent of a machine-family used to this very day in precision metalworking shops throughout the world.

Along with J. R. Brown's other major developments, the universal grinding machine was profoundly influential in setting the course of Brown & Sharpe for many years to come.

During his presidency, the company's physical plant was enormously expanded, and the length and breadth of the Brown & Sharpe machine tool line became the greatest in the world.

In the grinding machine field, expansion went far from universal grinders alone and took in cylindrical grinders, surface grinders, and a wide variety of special and semi-special models.

Recently added is the Brown & Sharpe turret drilling machine which introduces the company to an entirely new field of tool development.

But more important, we believe, it must concentrate on the development of entirely new concepts in textile processing as do the Unifil loom winder and our more recent Uniconer automatic coning machine.

This machine, operating at speeds up to 350,000 revolutions per minute, is believed to provide one of the fastest mechanical operations in industry today.

Major activity at Providence in 1961 will involve the scheduled completion of tooling for production of the Uniconer automatic coning machine.

This machine was demonstrated in two textile machinery exhibitions last year and was well received by the industry.

The potential market for the machine should be comparable to that of the Unifil loom winder.

Many mills have already placed firm orders for this machine.

A new spinning take-up machine has been developed to facilitate the use of our take-up machine in the production of thermoplastic yarns.

This new machine takes up filament yarn from spinneret or extruder and winds large packages at speeds up to 6,000 feet per minute.

During the year our British subsidiary, Leesona-Holt, Limited, expanded its plant in Darwen, England, and added machine tool capacity.

A little extra work here will pay off with a smooth, snug-fitting machine when you are finished.

The cleaner air means less time spent pushing a vacuum, fewer trips to the dry cleaners, lighter loads for the washing machine.

A relatively simple switching arrangement reverses the cycle so that the machine literally runs backward, and the heat is extracted from outdoor air and turned indoors.

Now, the machine has been improved to a point where it is generally more economical than oil heat at temperatures down to 15 degrees.

The body is a heat machine, and 20 to 25 guests can easily double your cooling load.

A BTU is a unit of heat, and the BTU rating of a conditioner refers to how much heat your machine can pump out of your house in an hour.

Electronics has been applied to medicine for many years in the form of such familiar equipment as the x-ray machine, the electrocardiograph, and the diathermy machine.
