Title: Optical surface monitoring of rotating symmetrical body - using electronic camera and comparison of brightness of adjacent image elements on circular paths
Inventor: WIRNITZER BERNHARD DR
IPC: G01N21/954
Filed: 1989-11-20
Abstract: The optical surface monitoring of a rotation symmetrical body involves placing it on a support and electronically scanning the surface with a camera. The brightness of adjacent image elements is compared with a predefined desired value to qualitatively evaluate the surface quality.

Patent DE-4004161-A1 (DE)
Inventor: KOBLITZ RUDOLF DR ING
IPC: H04N3/24
Filed: 1990-02-10
Abstract: A scanning circuit which utilizes blanking pulses between flyback pulses in a display device includes a line blanking circuit which prevents the generation of spurious blanking pulses by ringing in the blanking pulses. The line blanking circuit includes a capacitor for storing a reference voltage. A comparator is responsive to the reference voltage and to the flyback pulses and provides the blanking pulses when the flyback pulses exceed the reference voltage. The comparator is prevented from resetting for a preselected time period after the falling edge of the blanking pulse and spurious blanking pulses can not be generated during the preselected time period.
Patent DE-4006413-A1 (DE)
Title: Stretch film for e.g. sealing green fodder - is coated with aq. dispersion of specific polymer adhesive on one or both sides, produces airtight wrap, and is physiologically harmless
Inventor: OGGESEN HEINRICH
IPC: C09J7/20
Filed: 1990-03-01
Abstract: A stretch film, for wrapping round packages, is coated with an adhesive dispersion on at least one side. It can have an uncoated strip on each side. To produce the material a film (1) is drawn between a rubberised roller (3) and a metal backing roller (4) and then reeled. This roller (3) touches a metal engraved roller (5) whose surface has a fine relief pattern so as to pick up a liq. dispersion of adhesive from or adjacent rubber roller (6). This last roller (6) dips into a tank (7) of the aq. dispersion (8). All rollers (3-7) are driven. When the finished stretch film is used for wrapping purposes and water escapes from the coating this provides an air-tight seal. The prod. is partic. suitable for use in wrapping green fodders for silage. If the film is left with an uncoated strip a few mm wide this prevents sticking between layers. Suitable adhesive dispersions are modified terpolymer of ethylenevinylacetate-acrylate, or its mixt. with ethylene-vinylacetate, or acrylicester-ethylene copolymer plus additives. ADVANTAGE - The film provides an absolutely air-tight wrap which retains its seal over long periods. It therefore does not affect the environment. It is free from organic solvents. It is physiologically harmless and therefore suitable for foodstuffs.
