Patent ES-348680-A1 (ES)
Title: Monitoring and sorting arrangement for mass-produced articles
IPC: B07C5/344
Filed: 1967-12-27
Abstract: A method of sorting mass produced articles includes measuring one particular characteristic of each article or of one or more samples in a batch of articles and comparing the measured value with the mean value A of the same characteristic of a plurality of previously sorted articles or samples, the mean value being increased or decreased to a new value A1 whenever the measured value exceeds A+a or falls below A-a, respectively, "a" being an arbitrary constant, the range changing to A1 a when A changes to A1, and rejecting an article whenever the measured value falls outside the range A r, "r" being an arbitrary constant greater than "a", the range changing to A1 r when A changes to A1. In sorting Leclanche cells, the e. m. f. Ai, Fig. 3, a cell is compared with the median A of the end's of a plurality of previously sorted cells, and an output pulse of 50m sec. duration representing the difference is fed to a unit B, also supplied by a multivibrator C operating at 2000Hz, the output of B being a train of pulses oscillating about zero and having a phase shift dependent on the polarity of the 50m sec. pulses. The output of B is fed through a preamplifier E to a rejection channel 14 and a phase converter F which produces complementary signals, one in phase with and the other out of phase with the output of unit B, the outputs of F being respectively amplified at G1, G2 and passed to demodulators H1, H2, one of which, depending on the polarity of the 50m sec. pulse, produces a negative d.c. voltage. If Ai exceeds A, H1 produces the negative voltage, which, if Ai exceeds A+a, is sufficiently large to overcome the threshold of a Zener diode associated with a threshold circuit S1, thus feeding a train of pulses to an integrator I1 causing an adjusting device T1 to increase A. The integrator prevents A being changed by noise signals. Channel 16 operates if Ai falls below A, causing T2 to reduce A if Ai falls below A-a. Rejection channel 14 is similar to channels 15, 16 but includes a timing circuit 17 which controls the openings of a trap door 18 where the defective cell reaches it. The invention is also applicable to sorting articles according to their physical dimensions.

Title: Building of underground partition walls
IPC: E02D5/18
Filed: 1969-08-14
Abstract: A method for the construction of subterranean partitions or diaphragm walls in concrete, of the type in which a trench is excavated in the ground by known means so that when the casting concrete is effected, the walls of the trench assume directly the function of moulding boxes. Prior to pouring the concrete, a set of metal stressing members, such as high tensile strength steel, is inserted into the trench according to a pre-determined profile. After the concrete has set, the said stressing members are subjected to a traction force to induce a prestress adapted to give the wall pre-inflection in a selected direction and amount. Since the concrete is in the trench and in intimate contact with the walls thereof, the traction force applied is of such a degree that, if the same force were applied to a similar wall element outside the earth, such a wall element would fail and crack.
