Patent CA-2157442-A1 (CA)
Inventor: SUGO TAKANOBU
IPC: C08J5/20
Filed: 1995-09-01
Abstract: Separation functional fibers are produced by exposing fibers with a core/sheath structure to an ionizing radiation and then grafting a polymerizable monomer to the fibers. Ion-exchange fibers are produced by introducing, through radiation-initiated graft polymerization, ion-exchange groups into the sheath of each of composite fibers the core and the sheath of which are composed of different kinds of high-polymer components. The separation functional fibers and the ion-exchange fibers are useful in various applications such as the production of pure water in electric power, nuclear, electronic and pharmaceutical industries and the demineralization of high-salt content solutions in the production of foods and chemicals. The fibers are also useful in removing harmful components from gases, as well as odorous components such as ammonia.

Patent CA-2162419-A1 (CA)
Inventor: BROWN JEFFREY
IPC: G05B19/4065
Filed: 1995-11-08
Abstract: A chip buildup detection and control apparatus having a flow transducer and flow monitor to measure and monitor coolant flow to a cutter of a machine tool for detecting excessive chip buildup on the cutter and removing the buildup on the cutter which decreases machining cycle time while increasing cutter life and machine tool production. Excessive chip buildup on the cutter is detected when coolant flow to the cutter drops below a minimum flow rate limit. Buildup is removed upon detection by initiating a "pecking" cycle where the cutter is retracted from its position of engagement with the workpiece being machined for a predetermined dwell period of time. The machining cycle is aborted if coolant flow does not rise above the minimum limit by the end of the dwell period. If coolant flow rises above the minimum flow limit, the cutter is advanced almost to its previous position of engagement with the  workpiece  and machining  is  resumed.  Preferably,  if coolant flow to the cutter rises above a maximum flow rate limit, the "pecking" cycle is initiated and, thereafter, the machining cycle is aborted if flow does not drop below the maximum limit during a predetermined dwell period. In a preferred embodiment, a "pecking" cycle is initiated if coolant flow to the cutter falls outside a normal flow rate window of between the minimum and maximum flow rate limits. Therefore,  "pecking" cycles are only initiated when  excessive  chip  buildup  or  cutter  failure  is detected.

IPC: A01K61/00
Filed: 1996-10-31
Abstract: A device and method for volitionally orienting fish relies upon the instinctive reactions of fish in order to ensure that when the fish exit a containing vessel, they do so with a uniform anatomical orientation, such as head-first, dorsal-side-up.  The containing vessel is partially filed with water and has at least one exit.  A flow of water is generated away from the exit of the vessel, causing any fish that are introduced into the vessel to orient themselves head-first into the direction of the flow.   In addition, an environment within the water of the vessel may be created that is disturbing to the fish, thereby causing the fish to want to exit the vessel.  In order for the fish to exit the vessel, they must actively swim toward and through the exit opening.  After the fish exit the vessel, they may then be subjected to any number of fish handling operations -- such as automated vaccinating, tagging/marking, sorting, and/or counting -- where it may be beneficial to have fish delivered to a given location at a high rate of speed and with a uniform orientation.

Abstract: A warning system for alerting a person to an emergency situation which includes a transmitter responsive to a visual or acoustic alerting system for transmitting an alarm signal on an RF carrier and a control signal on a sideband of the carrier. A tuneable receiver for receiving commercial broadcasts in a normal operating mode transfers to an emergency mode upon detection of the control signal and converts the alarm signal to an acoustic signal. In one embodiment, the visual or acoustic alerting system is a siren and light system of an emergency vehicle. In this embodiment, a transceiver is preferably included for dedicated communications among emergency vehicles. The range of both the transmitter and transceiver complement and are substantially the same as the effective range of the visual or acoustic alerting system.

Abstract: Soil including sand and clays contaminated with nuclear waste materials, elemental mercury or as mixed waste with hazardous organic compounds are decontaminated by treating with anhydrous liquid ammonia alone or with solvated electrons. Methods comprise concentrating radionuclides, such as plutonium and uranium in the fines of soil and clay to yield residual soil products which are sufficiently free of contaminants to allow reclamation. By concentrating nuclear wastes in soil fines space requirements ordinarily needed for storage of untreated soil and handling costs can be significantly reduced. Ammoniacal liquids, such as anhydrous liquid ammonia facilitates decontamination by breaking up soil into fine slurries for releasing droplets of mercury metal. The high density of the mercury permits precipitation with larger soil particles and for recovery from soil particulates.

Abstract: In a regional telephone network system offering centrex services, a closed user group is distributed as subgroups to several different telephone exchanges. According to the invention, the management of user groups can be implemented in such a way that a table-type subscriber database is stored in each exchange with subscribers of at least one closed user group. The database is associated with this user group and contains all information necessary for implementing centrex services so that when the call control of the exchange detects on the basis of the subscriber data that the subscriber belongs to the closed user group, it utilizes the subscriber database when establishing a call.
