Abstract: Aqueous grouting compositions based on high alumina cement have th onset of setting delayed for upwards of one month by the incorporation therein of a set-inhibiting agent such as boric acid or gluconic acid delta lactone and can then be rapidly reactivated for use by the incorporation therein of a reactivator, for example lithium carbonate, to produce a high strength hardened cementitious composition. The reactivated composition can advantageously be used to anchor a reinforcing element such as a rockbolt or dowel in a borehole and for this purpose the set-inhibited cementitious composition and the reactivator can be packaged in the separate compartments respectively of a dual-compartment frangible cartridge.

Abstract: A microprocessor-based zero crossing circuit produces in response to an input command provided by closure of a switch (18) an output signal (13, 14) which is synchronised with the zero crossing points of an a.c. supply and includes a predetermined delay. By this means the output signal (13, 14) may be used to operate or control operation of, for example, a circuit breaker (Figure 2; Figure 3) for the a.c. supply in order to minimise contact arcing. The circuit is useful in an electricity supply meter when the input command on input 12 is generated by a credit or pre-payment mechanism which acts to cut-off an a.c. supply on expiry of credit. Following a cut-off command on input 12 the circuit produces the synchronised output signal (13, 14) appropriately delayed to take into account the operating time of the circuit breaker (Figure 2; Figure 3) so that its contacts (20, 21) open as nearly coincident as possible with a zero crossing point of the supply.

Généralement, des barres de bus métalliques rectangulaires (non illustrées) sont boulonnées aux arrière-plans en utilisant des trous traversants plaqués (20b-e) afin d'établir le contact avec les zones exposées (17b-e). Les trous traversant les couches sont obtenus et préparés de manière que chaque trou (15, 20 et 22) soit en contact avec une couche conductrice particulière désirée ou dans le cas d'une mise à la terre avec toutes les couches conduisant à la terre. Les couches conductrices (10a et 10i) peuvent être utilisées comme couches de signaux utilisant des tracés (14) et des trous (15) tandis que les couches (10b-h) sont appelées plans d'alimentation.

Abstract: Procédé de production d'un carbure de silicium fritté possédant une résistance élevée à des températures élevées et une structure fine uniforme, consistant à permettre à un polymère d'organo-silicium d'être présent à la surface de particules de SiC de départ ayant une taille inférieure ou égale à 1 mu, pour précipiter des particules SiC superfines produites à partir du polymère d'organo-silicium sur les particules de SiC de départ dans une étape de chauffage avant l'étape de frittage. Les particules de SiC superfines sont extrêmement actives en comparaison avec les particules SiC de départ et sont précipitées efficacement entre les particules SiC de départ, une partie de ces particules servant ainsi à lier entre elles les particules SiC de départ. Il est ainsi possible d'améliorer sensiblement l'aptitude au frittage d'un moulage, et le frittage peut être exécuté dans une atmosphère contenant de l'azote sans provoquer de réduction de densité ou une détérioration des propriétés liantes.
