Title: Signal separator having function of subsampling digital composite video signal
Inventor: YAMADA MASAHIRO
IPC: H04N9/78
Filed: 1988-12-23
Granted: 1992-05-12
Abstract: Abstract of the Disclosure A signal separator includes an A/D converter which samples a composite color television signal including a luminance signal component and a color difference signal component at a sampling frequency four times a frequency of a chrominance subcarrier and outputs a digital signal.  A timing signal generator receives the digital signal and generates at least first and second timing signals.  A subsampling circuit subsamples the digital signal in accordance with the first timing signal and outputs a subsampled signal.  A frame delaying circuit delays the subsampled signal by one frame and outputs a delayed signal.  The signal separator further includes first interpolation circuit which interpolates the delayed signal in accordance with the second timing signal and outputs a first interpolated signal.  A first separator separates the color difference signal com-ponent from the composite color television signal by mixing the first interpolated signal and the digital signal.  A second interpolation circuit interpolates the color difference signal component by a predetermined signal and outputs a second interpolated signal.  A second separator separates the luminance signal compo-nent by mixing the first interpolated signal and the second interpolated signal.

Filed: 1989-02-20
Granted: 1994-02-15
Abstract: FOIL PRESSING SYSTEM FOR NECKED BOTTLE TYPE CONTAINERS           ABSTRACT OF THE DISCLOSURE    This invention relates to a pressing station for metal foil sheets applied around the top and neck of bottles.  By means of bell-shaped pressing elements which can be axially lowered toward the bottle top, the foil sheets are firmly applied to the top and neck of the bottle.  The pressing elements corresponding to each receiving position of the delivery star wheel are each supported by a crank.  By means of a three-dimensional drive mechanism, each crank and thus also each pressing element can be lowered to the top of a bottle.  To prevent collisions in the overlapping area of the rotational paths of the turntable and the delivery star wheel, each crank is coupled with another drive mechanism, which engages the crank.  The cams of the two cam drive mechanisms are designed so that the pressing element is in its raised inside position in the vicinity of the turntable, and in its lowered, outside position in a portion of the area between the turntable and the delivery of the delivery star wheel.

Abstract: INVENTOR:  WERNER HONEGGER            INVENTION: METHOD OF AND APPARATUS FOR OUTFEEDING PRINTED            PRODUCTS ARRIVING IN AN IMBRICATED FORMATION     ABSTRACT OF THE DISCLOSURE     The band or belt conveyor conveys the printed products arranged in an imbricated formation to a take-over region.  In the imbricated formation, each printed product lies upon the next following or trailing printed product.  An outfeed device, whose conveying direction extends in the take-over region from below towards the top,  comprises grippers pivotably mounted at a revolvingly driven traction element.  The conveying speeds of the band or belt conveyor and the outfeed device, respectively, are co-ordinated such that in each case two infed printed products are introduced into one open gripper.  The depth of the grippers is larger than the spacing or pitch between the leading product edges of the printed products in the infed imbricated formation, so that the two printed products engaged or seized by one gripper can be outfed with unchanged mutual spacing or pitch.          Imbricated formations can be thus formed during delivery or outfeed of the printed products.   In  such  imbricated formations the printed products are arranged at an imbricated spacing or pitch which is substantially the same as the original spacing or pitch.

Granted: 1993-08-31
Abstract: A SYSTEM FOR REDUCING NOISE HOLOGRAMS                    ABSTRACT OF THE DISCLOSURE           A hologram recording assembly includes a transparent, absorbent member supported on a substrate. The transparent member is positioned to be directly incident to an exposure beam. The transparent member is out of moisture equilibrium during an exposure time. Consequently, the transparent member increases or decreases in thickness depending on a moisture difference between it and the environment. As the thickness changes, a phase shift in the light reflections within the recording assembly blurs spurious holograms while leaving the desired hologram intact.
