Title: Linear distortion evaluator for TV signal - forms specified time integral of evaluation functions prod. to give measure of signal quality
Inventor: SCHROEDER HARTMUT DIPL ING
IPC: H04N17/00
Filed: 1976-09-27
Abstract: The linear distortion evaluator, for a television signal, derives a quality or error criterion from the behaviour of a transmitted test signal. The criterion is obtained from the magnitude of the time integral of the product of a power (the square) of a second evaluation function (w(t)) with a power (the square) of the magnitude of the convolution product. The convolution product is formed by multiplying a first evaluation function (g(t)) with the frequency deviation (e(t)) in a given frequency range. A comparator (3) compares a reference (4) with the t.v. signal to give the (e(t)) function, which is then filtered (5) to give the convolution product. The product is then multiplied with the second evaluation function and the result squared (8) and integrated (9).

Title: Washing out concrete residues - by pumping resulting slurry through hydrocyclone where only larger particles are sepd. off and the remainder are kept as slurry
Inventor: RIKER RUDOLF ING GRAD
IPC: B03B9/06
Filed: 1978-10-28
Abstract: Particles thick can be lighter or heavier than water result when concrete residues are washed out. The system has a wash plank, a separation system and a sludge system. The system has a hydrocyclone located between the sludge sump and the various wash systems. This cyclone serves to classify slurry pumped to it into two fractions. The particles size of one fraction is 0.06-3mm. That of the second is from 0-0.06 mm. The precise fractions depend of course on the density of the particles. The coarser fraction is recycled to the general coarse product. The fines are removed as a sludge. For use with cement and concrete mixing and prepn. systems. Thin concrete slurries tend to separate into fractions but can cause severe environment problems, particularly as the deposits will set rock hard. The systems removes the heavier particles which tend to settle out and leaves only those which remain suspended.

Patent DE-2851093-A1 (DE)
Inventor: MEIER OSKAR
IPC: B65D90/24
Filed: 1978-11-25
Abstract: If as a result of accident events, such as collisions, storage containers of road or rail tank trucks are damaged, extremely rapid intervention is necessary in order to prevent damage to the environment depending on the contents transported. The collection container consists of a film tube (9) whose closure part (10) has inflatable beads (11a, 11b) so that the film tube can be placed as a collection basin below the leaking contents. If the closure part is to be attached to the damaged container, a ring (31) is fitted over a partially pumped-up closure bead (11a) and attached to the container (3) over the damage point by means of eyes (19) and fastening cords (21). The bead (11a) placed between the container and the ring is pumped up so that it rests firmly against the container wall and forms a seal around its damage point (5). The use of a film tube allows a large collection volume to be provided with only the least possible storage volume for the collection container. The film tube, which is preferably rolled up in the empty state, can also readily be carried to inaccessible accident locations. <IMAGE>

Title: Inductive flowmeter for conductive liq. - has evaluator circuit using only harmonic of measuring voltage generated by magnetic flux
Inventor: APPEL EGGERT ING GRAD
IPC: G01P5/08
Filed: 1979-01-18
Abstract: The inductive flowmeter has a sensor tube with a dielectric coating, in which are two measurement electrodes supplying measurement voltage to an evaluation circuit, and which is subjected to a periodic magnetic flux. A switch connects the electrodes to the circuit only during the period of each cycle for which the rate of change of magnetic flux is zero. The zero flux rate of change period is held constant. The sensors results thus free of the time variation defects of known sensors. The evaluation circuit contains a circuit section which extracts a harmonic from the switched measurement voltage. The sensing period and accepted harmonic half-period are identical and equal to a whole number fraction of the zero flux rate of change period. The sewing period and accepted harmonic half-period are identical and equal to a whole number fraction of the zero flux rate of change period. The magnetic flux in successive half-periods may be of identical polarity, or alternately of opposite polarity.
