Patent DE-4208232-A1 (DE)
Inventor: HENTSCHKE SIEGBERT PROF DR ING
IPC: H03M3/00
Filed: 1992-03-14
Abstract: This description relates to digital-analog conversion permitting high amplitude precision even at a low number of quantisation stages. This is achieved by the super-sampling and filtering of the quantisation noise. The quantisation precision which is generally limited by process tolerances is compensated in the design proposed here by an additional logic. This permits the accurate linearity correction of an inaccurately given quantisation characteristic. The design is also made flexible by the fact that d/a conversion can be performed at a relatively low signal frequency with high resolution while even a high signal frequency with a coarser quantisation can be converted. The facility to perform any necessary analog filtration with steep edges digitally to economise on analog components is an additional advantage.

Patent DE-4215867-A1 (DE)
Inventor: GODDERIDGE VOLKER
IPC: B22C5/10
Filed: 1992-05-14
Abstract: The invention relates to a process for controlling the drag-out of sand, via an outlet tube arranged on the opposite side of a fluidised bed separator (furnace) to a sand feed, in the thermal regeneration of foundry sand, the bottom of the fluidised bed separator having openings through which hot gases pass into the fluidised bed.

Abstract: A method for printing process control on a printing press operating by the halftone method, in particular a sheet offset printing machine, in which, for example, measurement zones of the halftone and of the full tone are also printed and these are scanned photoelectrically, after which a conversion of these measurement values into an actual characteristic takes place, is to be improved to the effect that the characteristic achieved in printing can be matched to a given reference characteristic as far as possible over the entire course of the tonal value extent. The measurement values obtained are converted into an actual characteristic, a multiplicity of potentially achievable actual characteristics is calculated therefrom using process-related connections, and, from this group of achievable actual characteristics, the particular one is selected which corresponds to the greatest extent to the given reference characteristic based on a given quality criterion.

Title: Continuous degassing of thermoplastic polymer melt or soln. - contg. monomer and opt. thermally decomposed free radical initiator by using adiabatic heat of polymerisation for vaporisation
Inventor: THIELE REINER PROF DR
IPC: C08F6/00
Filed: 1992-10-23
Abstract: Continuous removal of volatiles from thermoplastic polymers (I), obtd. by bulk or soln. polymerisation of olefinically unsatd. monomers (II) with a thermally decomposed free radical initiator (III), involves reducing the pressure on a hot (I) melt or soln. The novelty is that the heat of vaporisation is (partly) supplied by adiabatic heating of the melt/soln. still contg. (II) and opt. (III). Pref. sufficient (III) and/or (II) is added to the melt/soln. leaving the polymerisation appts., then this is passed to the vaporiser. USE/ADVANTAGE - The process is useful for (I) producing continuously, e.g. polystyrene and analogues, e.g. poly-alpha-methylstyrene, polyacrylate esters, polydienes, polyvinyl cpds. and their copolymers. Adiabatic heating results from polymerisation of (II) and opt. (III) still present or of (II) alone if this can be polymerised thermally, as in the case of e.g. styrene.
