Title: Video disc player having timebase corrector and constant angular velocity turntable
Inventor: KELLEHER KEVIN C
IPC: G11B21/03
Filed: 1981-10-13
Granted: 1988-03-20
Abstract: The record-layer has a pck-up transducer which is movable tangentially by a transducer to correct for errors in the relative velocity between the transducer and the record, the transducer being part of a velocity correction servo which is responsive to a first signal component reproduced from the disc indicative of the relative velocity.  For a video disc player that first component is the burst component and the servo corrects for time base errors.  Owing to variation in information density on the disc with radial position, unit displacement of the transducer results in a varying displacement relative to the information on the disc.

Granted: 1992-10-13
Abstract: In a rolling mill wherein product is rolled continuously in successive first and second blocks at the finishing end of the mill, a pinch roll unit is interposed between the two blocks. The motor speed of the pinch roll unit is employed in combination with other variables to preset the motor speed of the second block prior to entry of the product front end therein. The preset motor speed of the second block produces an acceptable level of interblock product tension once the product has entered the second block. Thereafter, product elongation in the first block is monitored and required adjustments to the motor speed of the second block are made in order to maintain interblock product tension within acceptable limits.

Abstract: A device, utilizing a unique hemispherical cutter to remove a sample of material and to retain the sample of material for retrieval. The cutter is mounted on a chassis which can travel along the interior or exterior of the device to be sampled. The carriage can be maintained in a fixed position relative to the structure being sampled. After positioning of the cutter carrying carriage the cutter blade is pivoted into engagement with the surface. The blade penetrates the surface and removes a sample in a single continuous cut, leaving a shallow dimple. The sample is then retrieved through the return of the cutter and carriage from the device being sampled.
