Title: Two-component paste premixer - has structured inner walls to lay adjacent material strands in alternating layers and hence achieves a homogeneous mixt. with low delivery pressure
Inventor: PIESTERT GERHARD DR
IPC: B01F13/10
Filed: 1991-11-21
Abstract: To premix two paste masses, to be held in a static mixer, the masses are fed in adjacent strands to guide walls across their contact plane which lay the materials in alternating layers. Walls in the premixer pref. lie across the contact lane with the two material masses (A,B), arranged in a triangle. The point of the triangle is at the contact plane with the materials, and the side of the triangle opposite the point has a length matching the premixer dimensions. Two neighbouring walls, or one wall and the wall of premixer, are alternately to one side and the other through an angled wall, with a rounded transit between the angled wall and the other walls. The premixer is an injection moulded component. A non-twist lock is between the outlet connection and the premixer through an extension of the premixer inserted into the cartridge, in a keyed fit. A non-twist lock is at the upper end of the premixer, against the connected mixer, through a groove and key. The walls are at a variable gap from each other. The intersection at the lower edges of the angled walls runs away from a centre line of the premixer. USE/ADVANTAGE - The premixing is for two-component adhesives and sealants, which are finally mixed on delivery by an applicator gun or similar appts. The method achieves a homogenous mixt. of two materials, with a low delivery pressure.

To overcome the effects of intense and esp. impulsive noise, a median filter (16) is introduced comprising several delay devices (17) of pixel or line duration and a median selector (18). The correction factor (k) is then obtd. (12) conventionally. ADVANTAGE - Differencing of delayed and undelayed signals reduces or eliminates both uniformly distributed and impulsive noise, so that only interference is suppressed and signal components representing real movement are retained.
