Patent AU-538975-B2 (AU)
Title: Focus detector
Inventor: WINSLOW JOHN S
IPC: G02B27/40
Filed: 1981-05-14
Granted: 1984-09-06
Abstract: Electro-optical focus detection apparatus for providing a signal indicative of the magnitude and polarity of focus error in a light beam impinging on a surface, such as a recording surface in a recording or playback system. The detector includes a beam splitter for dividing the beam reflected from the recording surface into two reflected beams of equal power, and includes an aperture placed in the path of the two reflected beams. The first reflected beam converges at a focal point before encountering the aperture and the second reflected beam converges at a focal point after encountering the aperture, both beams thereafter impinging upon separate photodetector elements. The aperture reduces the light incident on the photodetectors from both reflected beams, and the apparatus is so configured that the powers of the reflected beams incident on the photodetector elements are identical when the original beam is in focus on the recording surface. When the original beam moves out of focus with the recording surface, both focal points of the reflected beams move in the same direction, to provide an increase in the light falling on one of the photodetector elements and a decrease in light falling on the other, such that the differential output derived from the photodetector elements provides a signal indicative of the magnitude and polarity of the focus error.

Title: Amplifier
Inventor: BLAUSCHILD ROBERT ALAN
IPC: H03F3/45
Filed: 1982-02-12
Granted: 1985-06-27
Abstract: A transconductance amplifier includes a differential transconductance amplifier stage (10, 11) and a differential correction amplifier stage (18, 19). In order to achieve substantially linear operation over a wide dynamic range, the effects of nonlinearities in the transconductance amplifier stage are substantially cancelled by the effects of nonlinearities in the correction amplifier stage. This is accomplished by cross-coupling the two stages and establishing the relative gain of the correction amplifier stage with respect to the transconductance amplifier stage such that the desired cancellation occurs. In a preferred embodiment, optimum cancellation occurs when the gain of the correction amplifier stage is substantially one-half the gain of the transconductance amplifier stage.

Title: Lubricant supply to roll-bearings on roll-stands - using retractable coupling units mounted in stands
IPC: F16N21/00
Filed: 1969-08-08
Abstract: Lubricant supply for the roll-bearings on roll-stands, with rigid lubricant pipes which connect with holes in the chock-guides and then to coupling units on the surface along which the chock slides, a pressure medium being used to press the coupling unit against the chock, the unit being retracted for roll changing. The novelty is that spring pressure is used to push the coupling unit back in the chock-guides, and the opening in the coupling unit through which the lubricant flows is large enough to continue the flow despite the movement of the lubricant feed-hole in the chock which occurs due to adjustment of the rolls. Several modifications are possible. The coupling unit can be retracted when a roll change is required.
