Abstract: A printing device comprises a platen (11) for supporting items on which text is to be printed, a printing head for printing text, the printing head comprising an array of cells (19) each containing an interchangeable type for printing a respective character, the types being slidable relative to the cells from a rest position to an impression position, the arrangement being such that return of each type towards its rest position from its impression position is effected by its resiliently rebounding from the platen (11), a trolley (14) carrying, the printing head and movable longitudinally relative to the platen between a number of print positions, a print hammer arrangement (20) for propelling the types to their impression positions, a linear motor (13) for causing said relative movement of the platen and trolley and circuitry for controlling the operation of the impelling means and the drive means. The position of the trolley may be under closed loop control. The printing head may be movably mounted on the trolley for movement in the horizontal and/or vertical directions, optionally by one or more linear motors and optionally with closed loop positional control.

Abstract: An apparatus for the production of calcium silicate based stone blanks including at least one mold into which a crude mixture is poured, the mixture comprising granulated silicate-containing material, lime, water, a cement and foam. The mold has a cover, a bottom and side plate, with one of the plates being movable to open and close the mold. The crude mixture is heated in the mold essentially uniformly to a temperature between 45 DEG  C. and 90 DEG C. until achieving the desired blank-strength by strength-forming reactions of the cement in the crude mixture. The heater used for this purpose is a high frequency voltage heater using two parts of the mold as condensor plates connectable with a high frequency voltage source. The formed stone blanks are thereafter removed from the mold and transferred to a transport station.

Abstract: Carrier particles whereon a metal from the group VIII of the periodic element system is fixed are dry-mixed with particles from hydrophobic material which is simultaneously a binder and may thus bind the carrier particles together. The thus obtained mixture is subjected to an agglomeration step. The resulting agglomerates are broken. The broken agglomerates are screened and that fraction with a grain size smaller than 1 mm is pressed into a cake at a pressure of 25 kg/cm 2  at the most. The press cake is rolled and catalyst particles are cut from the rolled cake. The catalyst particles are mixed with hydrophilic particles. The thus obtained mixture is used in an isotopic exchange column for separating tritium from aqueous effluents. In this column the effluents are lead in counter-current to gaseous hydrogen.

Abstract: Un circuit de decompte vertical dans un recepteur de television comprend un compteur de decomptage vertical d'ou une tranche est decodee et comparee en temps avec le signal de remise a zero du compteur. Lorsque le compteur est verrouille par l'impulsion d'arrivee de synchronisation verticale, le signal de remise a zero du compteur chevauche la tranche et il en resulte une detection de coincidence verticale. Lorsque deux de ces detections sont effectuees, un signal est applique au detecteur de phase (60) dans la boucle de verrouillage de phase horizontale pour diminuer son gain et par consequent la caracteristique de la bande passante de la boucle de verrouillage de phase obtenant ainsi une grande immunite au bruit. Si, d'autre part, un nombre predetermine de signaux de remise a zero du compteur sont recus et ne chevauchent pas la tranche, un signal est alors applique au detecteur de phase (60) qui augmente l'intensite du courant passant au travers de celui-ci pour augmenter son gain et donc augmenter la caracteristique de la bande passante de la boucle de verrouillage de phase horizontale pour obtenir de meilleures caracteristiques de rentree ou de temps d'acquisition.

Abstract: The Figure shows the optical diagram of a static photometric polarimeter for deriving information about a sample (S). A beam from a laser source passes through a beam splitter (BS) which reflects part of the beam to a detector (Do) and transmits the remainder towards the specimen (S). The transmitted beam is plane polarised in a plane at 45° to the incident plane. The reflection of the beam from the surface of sample (S) is passed to a polarizing beam splitter (PBS). One portion of the split reflected beam goes to a detector (D z ) which measures the perpendicular polarization component of the beam and the other portion of the split beam goes to the detector (Dp) which measures the parallel polarized portion of the reflected beam. The outputs of the detectors (Do), (D s ) and (Dp) are supplied to a data processor and information about the specimen derived.
