Abstract: Filter aid materials are treated with anion exchange resin particles having an average particle diameter from 0.05 to 1 micrometer to produce a filter aid composition wherein the anion exchange resin particles are electrostatically bonded to the filter aid material. The bonding may be sufficiently strong that the resin is substantially irremovable from the filter aid material which is preferably completely covered by the resin particles. The treatment may be effected by mixing the filter aid material and the resin particles in aqueous suspension then removing excess particles.

Abstract: The invention relates to magnetic heads intended to make use of very narrow (30 to 50  mu ) tracks on advancing magnetic media. Whereas a conventional magnetic head comprises a working face consisting of a magnetic material in which there is a fine non- magnetic air gap, the magnetic head according to the invention comprises, by contrast, a working face consisting of a non-magnetic material (10 + 11 + 12) in which two fine magnetic layers (7), separated by an air gap and perpendicular to the working face, are included. This head is obtained by hot-press bonding onto a slice (21) of non-magnetic material a plate (20) itself composed of magnetic (16) and non-magnetic (17) layers: the plate (20) thus supported is ground down to obtain a thickness equal to the track width.

Abstract: Procédé et dispositif de séchage d'une structure de plancher en béton (1) ainsi que du remplissage (4) et du plancher (5) associés. On fait circuler de l'air de séchage au travers d'un grand nombre de trous dans le plancher. On aménage des ouvertures de sortie et l'on insère dans les trous des tubes d'injection (10) reliés à une source d'air comprimé. Un courant d'air comprimé ayant un faible taux d'humidité absolu et à une température dépassant considérablement la température initiale de la structure de plancher est envoyé dans une couche perméable à l'air, par exemple le remplissage (4), par l'intermédiaire des tubes d'injection (10). Un radiateur (14) chauffe la surface du plancher à une température égale ou supérieure à la température du courant d'air comprimé. Après une diminution donnée de l'humidité relative de l'air dans la couche perméable à l'air, la température de l'air comprimé est diminuée et le chauffage du plancher est réduit, ce courant d'air comprimé plus froid étant maintenu jusqu'à obtention du séchage désiré du béton. Le cycle de chauffage et de refroidissement est répété aussi longtemps qu'il est nécessaire jusqu'à obtenir le résultat final désiré. La source d'air comprimé est équipée d'un dispositif de séchage, d'une batterie de refroidissement et d'une batterie de chauffage pour l'air.

Abstract: © A liquid ring pump with a conical or cylindrical port member (40) has a vent-recirculation port in the port member in addition to the conventional intake and discharge ports (42, 46). The vent-recirculation port communicates with the compression zone of the pump and is connected to a reservoir of pumping liquid maintained in the discharge portion (68) of the pump head (14a). When the pump is operating at relatively low compression ratios, the vent-recirculation port acts as a vent to prevent overcompression of the gas in the pump. At relatively high compression ratios, the vent-recirculation port recirculates pumping liquid from the reservoir, thereby increasing the maximum attainable compression ratio.
