Abstract: A method is disclosed for correcting measurement errors caused by clock deviations in a secondary radar system.      To determine any deviation of the clocks of two ground stations (S1, S2; ... S1, S4) from each other, two interrogation/reply cycles are performed in direct succession in opposite directions over the same transmission path (d1 + d2): - Interrogation by ground station S1, reception of the reply from airborne station BS by ground station S2. - Interrogation by ground station S2, reception of the reply by ground station S1.      The two transmission periods differ by twice the deviation of the clocks in the two ground stations S1, S2.      The measured deviation is used to correct the measured transit time values and/or to synchronize the clocks.      Synchronization of several ground stations with a master station is achieved by successive interrogation/ reply cycles between the master station (S1) and all other stations (S2 - S4).

Abstract: A process for the extraction of copper from a sulphide copper ore or concentrate comprises subjecting the ore or concentrate to a first leaching at an elevated temperature and pressure in the presence of oxygen and a lixiviant which comprises an acidic solution of chloride and bisulphate or sulphate ions to produce an insoluble basic copper sulphate. The basic copper sulphate so produced is leached in a second leaching preferably at atmospheric pressure with an acidic sulphate solution to dissolve the basic copper salt to produce a leach liquor containing copper sulphate in solution. The resulting leach liquor is subjected to solvent extraction to produce a copper concentrate solution and a raffinate comprising protons and bisulphate or sulphate ions in solution.      Protons, and bisulphate or sulphate ions are extracted from the raffinate to produce a sulphuric acid solution which sulphuric acid solution is then recycled to the first leaching at elevated pressure and temperature to serve as a source of bisulphate or sulphate ions in the lixiviant. According to a preferred embodiment, the extraction of the protons and bisulphate or sulphate ions from the raffinate is effected by means of an electrodialysis process. In alternative embodiments copper sulphate is also extracted from the raffinate and recycled to the first leaching step or alternatively a source of bisulphate or sulphate ions, such as a hydrolyzable metal sulphate, is introduced from another source.

Title: Composite communication network
Inventor: OKANOUE YASUYO
IPC: H04L12/46
Filed: 1993-11-26
Granted: 1999-10-05
Abstract: A composite communication network of a hierarchical structure including a subnetwork at least in part thereof has a gateway (GW) node having a control message communication medium which includes three or more routes. Routing of the network layer level is performed between GW nodes and routing of the data link layer level is conducted in the ring subnetwork. Each node in the ring has an NE address to be distinguished in the ring and a routing table which shows a routing direction corresponding to a destination node. When the GW node in the ring including a target of a control message receives a message, the GW node sets an NE address of the target node in the packet of the message as a destination address, and processes the packet for transmitting to the control message communication medium indicated in the routing table. The node that receives the packet carries out mapping of the destination NE address of the packet and NE address of its own node by means of a routing application protocol of the data link layer level. When the two addresses coincide, the node transmits the packet to the internal message processor, but when they do not coincide, the node transmits the packet to a neighboring node and routing of the control message is performed with reference to the data link layer level in the ring subnetwork.

Title: Fluid flow meter
Inventor: INGMAN DOV
IPC: G01F1/54
Filed: 1994-08-26
Granted: 1999-12-21
Abstract: The fluid flow meter includes a flexible membrane clamped between upstream and downstream centering springs to enhance membrane behavior and extend the fluid flow measurement range by automatically adaptively moving the apparent clamping points in response to flow rate. Adaptation of the clamping span alters the relative effective excess membrane length within the clamping span to adapt membrane behavior to flow rate.  The upstream centering spring includes a long leaf spring pair cantilevered into the clamping span from the clamping region.  The long leaf spring pair is sandwiched within a shorter leaf spring pair active at higher flow rates and formed as part of a guide extending to the chamber surface.  The membrane ends are narrowed upstream and downstream of the clamping span to reduce flutter while the upstream intake is split into even laminar flows. The fluid direction is substantially changed at the outlet to minimize membrane distortion.
