Title: Method and apparatus for particle size analysis
IPC: G01N15/02
Filed: 1978-05-08
Abstract: An on-line particle size analyzer which is able to take measurements on material flowing along a line in real time and thus enable automatic process controls to be effected. The apparatus periodically takes a sample of material, dilutes it to a predetermined concentration in a turbidimeter, and then passes it to one of a number of vertical sedimentation cells in which a particle size analysis is carried out. Each sedimentation cell is formed simply as an enlarged part of a line passing from the turbidimeter around a loop back to the turbidimeter and, in order to fill the respective sedimentation cell, the sample is pumped round the loop until steady-state conditions have been reached, whereupon the flow is stopped and measurements begun. When the measurements, which are carried out by optical means, are completed, the whole loop, including the sedimentation cell is automatically flushed out. A central control unit controls the sequence of operations, and enables virtually continuous monitoring of the material flowing down the line.

Patent ES-8200538-A1 (ES)
Title: Process for rapidly achieving stabilized X-ray emission from an X-ray tube.
IPC: H05G1/34
Filed: 1980-09-12
Abstract: An apparatus for rapidly achieving stabilized x-ray emissions from an x-ray tube is disclosed. The essentially constant currant characteristics of an x-ray tube are utilized so as to initially establish relatively low voltage (C) but approximately full current (A) operating condition in the x-ray tube during an initial tube preparation time period. Any relatively low energy x-rays emitted during this initial period are of little concern since they are readily absorbed by the usual beam hardening materials placed in the x-ray path. Once the x-ray tube has been stabilized at such relatively low energy output, the operating voltage may thereafter be very rapidly raised to normal operating levels (D) while permitting concurrent rapid stabilization of the relatively small corresponding further required increase in x-ray tube current (B) which, in turn, provides for rapid stabilization of the useful high energy x-ray tube emissions.

Title: Pipe connector.
IPC: F16B7/04
Filed: 1981-02-26
Abstract: A pipe connector for connection to a pipe having a plain end comprises a body having a profile matching that of the pipe, and a pair of jaws extending outwardly for insertion within the end of the pipe. The jaws are formed with oppositely directed clamping surfaces for engaging the inner wall surface of the pipe end. One of the jaws is fixed and integral with the body. The other jaw is pivotally mounted on the fixed jaw and is extended inwardly of the body where it is threadedly engaged by a screw which connects the pivoted jaw with the body so that by rotating the screw in the appropriate direction the pivoted jaw pivots away from or towards the fixed jaw to clamp or unclamp the jaws from the pipe. The screw thus provides a positive clamping force which greatly assists the dismantling of the connector from a pipe end when desired. The screw also retains the pivoted jaw in place and there are no loose parts to become lost.

Patent ES-8305544-A1 (ES)
Title: Method and apparatus for transmitting a digital signal
IPC: G11B20/18
Filed: 1982-07-16
Abstract: A PCM digital signal is provided with double-interleaving and error-correction encoding to protect against errors occurring during transmission, which can be carried out by magnetic recording and reproducing. The PCM signal is processed as error correcting blocks of several data word sequences and an associated error correction word sequence, and the double-interleaved sequences are then transmitted as transmission blocks. Up to one erroneous word in each error correction block can be corrected by using the error correction word sequence. Any uncorrectable word can be compensated by substituting a synthetic word interpolated from immediately preceding and following data words known to be correct. The distance between successive data words is made as great as possible so that a long burst error is unlikely to affect the ability to compensate uncorrectable errors. To achieve this, alternate words of the PCM signal are distributed to odd and even groups of sequences, and the interleaving is carried out by imparting different delay times to the respective sequences such that the greatest delay time imparted to the odd sequences is less than the shortest delay time imparted to the even sequences. The error correction word sequence is provided with a delay time intermediate the greatest delay time of the odd sequences and the shortest delay time of the even sequences.
