IPC: H04B15/02
Filed: 1988-05-19
Abstract: In a building (1) constructed so that its structure and apertures form an electromagnetic screening to prevent leakage of radio communications from within the building, any defect in the screening is detected by a system consisting of a plurality of sensors (4) distributed around each floor of the building to detect waves from every direction, linked to a unit (3) for checking the level of the radiation received from each sensor and comparing it with a normal value. 
     In the case when an abnormally high value at one sensor is detected, the output of a master radio unit (2) on that floor, used for communication within the building, is reduced (see Fig. 4) to reduce the leakage of radio waves to the outside, and an alarm is activated by a visual display (6) and/or printer (7), see Fig. 3, so that the defect can be rectified promptly.

Abstract: A particulate mass that can be dusty but is generally sticky, due to the presence of water, is converted to an apparently dry, non-dusty granular material by polymerising a polymerisable material within the mass and breaking the mass down to the desired granular form after the polymerisation has gone sufficiently far that the mass is substantially non-sticky but before the polymerisation is completed.

IPC: F16P3/16
Filed: 1988-11-21
Abstract: The die (14) of a press is suspended at a given distance (J) above the table (12) of the press by springs (26). Microcontacts (42) detect a displacement of the die (14) towards the table (12) over a distance (D) which is very much less than the distance (J). First of all, the operator drives down the punch (24) of the press with the aid of a pedal while holding manually the part (T) on the die (14). The change of state of a switch associated with each of the microcontacts (42) automatically stops the descent of the punch when the pressure applied to the part holds the latter, whilst thereby avoiding risk to the hands of the operator. Secondly, the latter applies the working pressure by simultaneously actuating the pedal and a double drive unit for simultaneous manual operations. <IMAGE>

Abstract: On évite la détérioration de l'image due à une défaillance de cellules de mémoire individuelles en enregistrant, avec les données se rapportant à chaque ligne du champ d'image, une valeur de code calculée en fonction de la valeur de chaque bit de données dans la ligne et de la position de chaque bit dans la ligne. On peut reproduire un signal d'image ainsi enregistré en transmettant chaque signal de ligne à un générateur de fonction (15) à un additionneur (16) et à un accumulateur (17) afin de recalculer une valeur de code au moyen de la même fonction utilisée durant l'enregistrement du signal, et en appliquant la valeur de code enregistrée à une bascule (21). Les résultats de sortie de l'accumulateur (17) et de la bascule (21) sont appliqués à un circuit soustracteur (25) et, lorsque celui-ci produit un signal de sortie différent de zéro, la valeur d'un tel signal servira d'indication à la fois de la position de n'importe quel bit unique défecteux et de la direction dans laquelle la valeur enregistrée est erronée.
