Oster BCBG08-C 6-Cup Glass Jar 8-Speed Blender, Brushed Nickel
List Price:  |
DescriptionBrought to you by the #1 Blender brand. A blender that's anything but basic.Your life isn't basic. Your blender shouldn't be either. With this Oster blender you don't have to sacrifice quality for simplicity. The large capacity, 6-cup glass jar is dishwasher safe and has been Thermal Shock tested so you can pull it out of a steamy dishwasher and safely make a frosty cold beverage right away. The stainless steel 'ice crusher' blade does just that so you get smooth frozen drinks every time. And 8 speeds and 450 watts give you the power to perform for every usage occasion from frozen beverages to dips, from sauces to smoothies, from soup to nuts. Like most Oster Blenders, it is made in North America and backed by the superior quality of All Metal Drive. Because the two pieces that connect are metal (instead of plastic), you get a more durable and longer-lasting blender that will function flawlessly, party after party, year after year. The competition just can't compare. No matter the occasion, party for 15 or smoothie for two, blending is better with an Oster blender. Features

What is a Medium Voltage (MV) AC Drive (Frequency Inverter)?
What is a Medium Voltage (MV) AC Drive (Frequency Inverter)?
Don't feel bad about being confused by "medium voltage drives" terminology. It's a confusing because it sounds like a technical term, but really it's marketing driven. Actually, there are two terms that can be confusing to anyone new to the field of automated control of electric motors.
Let us start with the word "drive." Also sometimes called an inverter, a drive is essentially a power amplifier that puts out the electric power needed by an electric motor based on the torque and/or speed called for by the controller, which is a digital computer tasked with overall system control. As the industry has shifted in favor of variable-speed drives, the role of the drive has become more important.
Variable-speed motor/drive combinations use a synchronous ac motor with an encoder built in. The encoder signals the motor's speed and phase angle to the drive, which must then match its output frequency to the motor speed and its output phase to produce the required torque.
To get the drive's power efficiently out to the load as mechanical power requires having enough voltage to drive enough current through the motor. The output power is, after all, the product of voltage times current. The ratio of the voltage to the current, on the other hand, defines an impedance for the drive/motor combination.
Copper resistance in the motor coils and power cables, as well as contact resistance in all the connections rob the system of power, however. The higher the circuit impedance compared to these parasitic impedances, the more efficient the overall system will be.
The graph below compares motor/drive impedance to a typical parasitic impedance level of one Ohm. Assuming we want the ratio to be one or two orders of magnitude, the chart shows how the supply voltage needed correlates with output power. Small, fractional horsepower motors (red line) work well from a few tens to a few hundreds of Volts. Larger motors require hundreds of Volts to run efficiently. As horsepower requirements climb, so do the drive voltage requirements.
What really drives people crazy is the term "medium voltage drive." It is a purely marketing term. From zero to 600 V is called "low voltage (LV)." "Medium voltage (MV)" is 600 V and above. There is no "high-voltage (HV)" designation.
Comparing this 600 V cutoff to the chart shows that low-voltage drives provide good efficiency up to several horsepower (10,000 W). Above 10 kW, however, medium voltage drives are needed. Voltages above a few thousand Volts, however, are needed only for the relatively few electric motor applications requiring hundreds of horsepower. Most applications requring that much mechanical output are currently served by internal combustion engines.

The Mouse and the Motorcycle [VHS]
List Price: |
DescriptionBored, bored, bored. That's how young Keith feels about being stranded at the time-worn Mountain View Inn with his parents. Then he meets Ralph, an equally stir-crazy mouse who quickly befriends Keith and begs to ride Keith's toy motorcycle. Soon Ralph masters the tiny two-wheeler and "rrroom-zzzooms" through the hotel hallways, dodging four-legged predators, adults, and the occasional vacuum; he even risks his furry skin to help Keith recover from a high fever. Based on Beverly Cleary's famous children's novel of the same name, this 42-minute video combines live-action talent (including Ray Walston as the wise bellhop) and award-winning stop-motion animation. While the dated look of the TV movie may not appeal to kids who prefer the heart-pumping action of computer-generated favorites such as Small Soldiers, its tame plot and relatively slow pace make The Mouse and the Motorcycle a healthy choice for families with 3- to 7-year-olds. Followed by an even popular sequel, Runaway Ralph. --Liane Thomas |

The Long, Long Trailer [VHS]
List Price: |
DescriptionSuccess in that newfangled television business prompted Lucille Ball and Desi Arnaz to bring their slapstick chemistry to the big screen, courtesy of a 28-foot monster of a trailer home. The Long, Long Trailer is one of those domestic nightmare movies, in which an ordinary couple has their existence upended by a new contraption: in this case, a lemon-yellow motor home. They make the mistake of towing said behemoth to Colorado, a honeymoon journey fraught with tilted axles and Lucy's ill-advised collection of large souvenir rocks. One disaster follows another, with the action rarely rising above the level of a sitcom (MGM's top director of musicals, Vincente Minnelli, is overqualified here). One notable exception: the climactic sequence, a funny-nervous crawl up an 8,000-foot mountain pass. The film was a box-office hit, proving that moviegoers would go to theaters to see a TV star's hair in its natural red color. --Robert Horton |
