Title: Etching compsn. for chromium-plated photogravure printing cylinders - comprises hydrochloric acid, glycerine, zinc chloride and sodium hypophosphate, and does not fume or leave corrosive residues
Inventor: LIEBSCHER HANS-JUERGEN
IPC: C23F1/26
Filed: 1976-12-01
Abstract: The acid used for deepening the recesses of photogravure cylinders consists of HCl with addn. of glycerine, Zn chloride and Na hypophosphite. Deepening of the recesses of Cr-plated photogravure cylinders provides more room for taking in printing ink, so that in colour-printing the colours become richer. Etching with conventional acids produces fumes which present health hazards and their residues cause corrosion and rusting of the printing machines. The new formulation in which the HCl is bound by glycerine, ZnCl2 and Na hypophosphite does not give off fumes during etching nor does any residue of it attacks the printing machine.

Title: Self cleaning dust filter with mechanical action - having metal rings on cylindrical sleeves activated by impulse generator on side
Inventor: RIEDEL ERICH O ING GRAD
IPC: B01D46/00
Filed: 1977-02-08
Abstract: Filter elements are mounted vertically in a filter housing and have their open ends directed upwards. They have at least one impulse element mounted on their lower ends. This serves to collect an impulse transmitted from an impulse generator. The filter elements are mounted at such close proximity that a mechanical impulse induces a pendulum motion in the bags and these then bump into neighbouring bags to induce motion in them. The impulse element should be located between the lower end and the upper quarter. For use with filters for cleaning air or other dust laden gas strains. Reverse jet filters are known but damage to bags can be excessive. The system described gives mechanical cleaning without costly mountings.

Title: Detector for defects in sawn timber - uses microwave radiation received by 2 closely adjacent antennae and combined with opposite phases
Inventor: TIURI MARTTI PROF
IPC: G01N22/00
Filed: 1977-03-22
Abstract: The detector uses r.f. energy for grading and classification of timber, esp. sawn timber. Knots in timber are detected when a microwave radiation from suitably shaped antenna passes through the timber, or is reflected from it. Radiation falling on one or several pairs of antennae is measured and knots are detected as sudden changes of intensity and/or phase of reflected or transmitted radiation. R.f. signals from a pair of antennae are combined with a relative phase shift of 180 deg., so that zero output at balance is displayed when both received signals are equal. If a knot is present, the output signal is clearly other than zero.

Title: A=D conversion system for voltages - has store charged and discharged in both direction, and sum of recharging intervals is required measure
Inventor: HORN KLAUS PROF DR ING
IPC: H03M1/00
Filed: 1977-11-24
Abstract: The conversion is done by the multiple integration principle. In a first step a charge store is charged during a specified time interval, and then it is recharged by a reference voltage, with the charging time counted. The charge store is in a third step charged with the measurement voltage with reversed polarity (Ux) during the same specified time interval (N. To) and in a fourth step is charged again by the reference voltage (UN) until the voltage threshold (USt) is reached. The necessary time (n2. To) is again counted. The measurement (Ux) and the reference (UN) voltages are in turn passed through a preamplifier (V1), and the sume of counts during the second and fourth steps is the measures for the test voltage (Ux).
