Rentrak Corporation is currently a global media measurement and research company serving the entertainment industry. Rentrak began as a nationwide video chain named National Video, which was founded and incorporated in 1977. National Video founder Ron Berger developed what is now known as the pay-per-transaction (PPT) system, which allows studios and retailers to lease movie titles instead of purchasing them. The company went public in 1986. In 1988, facing competition from rival Blockbuster Video, Berger sold the National Video franchise chain and renamed the company Rentrak. Pat 4864898 - Can openers are designed to open a sealed aperture in the top of the can. However, none of these openers provides for normal flow of the liquid contents from the can because of the presence of an air lock formed within the can when it is inverted to pour out its contents. The air lock results in a reduced, irregular discharge of the liquid contents from the can. This patent was for an invention that prevents the formation of an air lock in the opening of a sealed can for facilitating discharge of the liquid contents in a uniform, maximum flow rate from the can.
