A $10 million cement mixer was built in the late 1960s and was used by a cement company for decades, according to a new book.

Now, the inventor of the product has died.

Robert L. Sperling died of heart failure in San Francisco in August.

His work is credited with making cement a staple of the American home.

He built the mixer to combine wet cement with fresh cement.

“A good mixer is an object of pleasure,” Sperler once said.

“Its sole function is to mix cement and make a very good product.”

The first version of the mixer, called the Stump Mixer, sold for $5,500.

In 1966, Sperlin built a second mixer called the Cement Mixer that sold for about $20,000.

In 1969, the company that made the mixer went out of business.

Today, the only surviving version of Sperlings mixer is called the Supermixer.

“We had the idea of making a mixer with a cement-type mixture, but we could not make the right product for our customers,” Saperlin said in a 2014 interview with ABC News.

The Supermixers first run in the U.S. came in 1967 and sold for more than $1 million.

Saperlings made about 30,000 of them before he sold them to another cement mixer maker.

“I have had some very sad and tragic experiences in my life, and this is one of them,” Soderling said in the 2014 interview.

“The first time I got to see my mixer in operation was in 1972, when the C-3PO movie came out.

It was a real blast.

It gave me an opportunity to be in the right place at the right time.”

The Super Mixers first appearance was in a 1978 episode of Star Wars.

A new mixer appeared in 1977.

“In fact, I’m still using this mixer today,” Skerling said at the time.

“It’s just not as good as it used to be.”

The new mixer made by Sperlings was built to last for decades.

In 2007, Saperling was named as the first person in history to be awarded a Nobel Peace Prize for his work.

The cement mixer also helped make cement a mainstream product.

It became one of the main ingredients in a variety of home construction materials, including brick and stone.

The product made from cement has also been used to build skyscrapers and skyscraping in New York, Los Angeles, Seattle and other major cities.
