Title: Biooxidation of refractory sulfide ores
Inventor: KOHR WILLIAM JACK
IPC: C12P3/00
Filed: 1994-12-02
Abstract: A method of recovering precious metal values from refractory sulfide ores is provided. The method includes the steps of separating clays and fines from a crushed refractory sulfide ore (12, 24), forming a heap from the refractory sulfide ore (18), bioleaching the heap to thereby oxidize iron sulfides contained therein (18), and hydrometallurgically treating the bioleached ore to recover the precious metal values. If sufficient quantity of precious metal values are contained in the separated clays and fines, these materials can be further processed to recover the precious metal values contained therein.

Patent CA-2179194-A1 (CA)
Inventor: HOWITT ANDREW WILSON
IPC: G10L25/93
Filed: 1994-12-12
Abstract: La compression de la parole s'effectue par étapes multiples (12, 14) de manière à augmenter la compression globale entre le signal vocal analogique (80) entrant et le signal vocal numérisé obtenu par rapport au résultat obtenu en seulement une étape de compression. Un premier type de compression s'effectue sur un signal vocal (15) de manière à produire un signal intermédiaire (44) comprimé par rapport au signal vocal (15), et un deuxième type de compression différent s'effectue sur le signal intermédiaire (40) de manière à produire un signal de sortie (42) encore plus comprimé. On obtient ainsi une compression supérieure à 1920 bits par seconde (et approchant 960 bits par seconde) sans sacrifier l'intelligibilité du signal vocal analogique (15) reconstruit par la suite. La compression de la parole s'effectue également par reconnaissance des parties redondantes dudit signal vocal (15) telles que les silences et par remplacement de ces dernières par un code spécial dans ledit signal comprimé (40). La compression totale supérieure permet, entre autres avantages, de transmettre les signaux vocaux en nettement moins de temps qu'il ne serait autrement possible, ce qui permet de réduire les coûts.

Title: Selective calling receiver and system for sharing selective calling numbers and information calling numbers
Inventor: AMMA SADAYUKI
IPC: H04W88/02
Filed: 1997-06-20
Abstract: A paging system (selective calling receiver system) has a transmission sequence between a base station and a pager (selective calling receiver). The base station of the system transmits one of the calling numbers assigned to the pager based on a predetermined timing sequence. The pager receives a calling number from the base station. A memory of the pager stores calling numbers and prohibited codes assigned there to. The prohibit codes indicates whether the stored calling numbers are allowed or prohibited, and is coordinated with the predetermined timing sequence of the base station. The pager evaluates whether the received calling number is the same as one of the allowed calling numbers stored in the memory and notifies a user of the pager of receipt of an allowed call.

IPC: D21F3/04
Filed: 1997-08-19
Abstract: The press section of a paper machine dewaters a watery fibrous pulp sheet which is guided along with a continuous circulating felt belt through two sequentially-arranged press openings. The felt belt is dried by a conditioning device positioned between the two press openings, and the felt belt is again dried with the aid of another conditioning device after it exits the second press opening but before it returns to the first press opening. By quickly separating the felt belt from the watery fibrous pulp sheet after they pass through the press openings, reverse moistening of the felt belt is effectively prevented. A smooth, soft press belt preferably guides the fibrous pulp sheet between the two press openings.
