Abstract:
A target (1) for use with a projectile has a web (7) defining a target face and a back board (29). The target face is divided into multiple segments (3, 5). A cup (19) filled with a projectile-receptive insert material (27) is mounted for sliding within each segment. Each cup has one or more resilient cushions (35) between the cup and the back board. Each cushion has at least one electroconductive area. The back board has pairs of switch contacts (25), forming electrical switches. The projectile impacting a cup at the target face with sufficient force causes the cup to slide within the segment urging the electroconductive area of the one or more cushions to touch the switch contacts, resulting in closing of the switch defined by the switch contacts and signaling a hit to onboard electronic circuitry. The at least one cushions beneath that cup return the cup substantially to its original position.

Abstract:
The invention provides an apparatus (10) for mounting at least one electronic financial transaction (EFT) data input device (34) to a surface. The apparatus (10) comprises a mounting platform (12) which is fixedly attachable to said surface; and at least one adaptor (14) which, in use, receives and secures a first EFT data input device (34) thereto, wherein said at least one adaptor (14) is detachably mountable to said mounting platform (12).
Abstract:
Monitoring network link quality in a telecommunications network which includes a plurality of intermediate network elements connected to network links via which communications sessions are conducted between respective terminating devices. A communications session comprises signalling procedures relating to the control of the session and media transfer procedures for transmitting media content via a media path established using at least part of the procedures. The established media path includes media path legs which are each established between respective media path leg endpoints connected via a network link. One or more endpoints of a media path leg is determined from at least part of the procedures. The determined one or more endpoints includes a media path leg end point at an intermediate network element. Reporting data is generated that comprises data identifying the determined one or more endpoints. The reporting data is transmitted to an analysis system for network link quality analysis.
Abstract:
A rotary disc filter is provided with an integrated backwash and chemical cleaning system. In one mode of operation, backwash is directed through a control valve to one or more nozzles for spraying the backwash onto the filter media forming a part of a rotary disc filter. In a second mode, a chemical cleaning mode, the pump directs backwash through an eductor that induces a chemical into the inductor which is mixed with the backwash to form a backwash-chemical mixture that is sprayed onto the filter media. A control system is used in conjunction with the backwash and cleaning systems to monitor process information and/or filter media properties and to determine when to perform backwashes and regenerative cleanings in order to optimize the performance of the filter system.
Abstract:
A disc filter having a controller for controlling or minimizing effluent surges is provided. The disc filter is operative to carry out a method or process for controlling the flow of effluent produced by the disc filter. The basic method entails sensing one or more process variables 5 that are a function of the effluent, and based at least in part on the sensed process variables, the disc filter controls the flow of the effluent by implementing various control functions such as: 1) rotating the rotary filter discs of the disc filter one revolution or less without backwashing; 2) rotating the rotary filter discs more than one revolution at a relatively slow speed without backwashing; 3) rotating the rotary filter discs for one revolution or more at a relatively slow 10 speed while backwashing; 4) rotating the rotary filter discs at a relatively high speed with or without backwashing; and 5) rotating the filter discs one revolution or more and periodically backwashing.

More specifically, the present invention provides a navigation system comprising medical instruments having electromagnetic tracking functionality and the integration of previously acquired imaging into a user interface of the navigation system.
Abstract:
A device for dissecting tissue and/or guidance of a second device to a desired physiological location, the device comprising: an elongate shaft comprising a proximal portion and a distal portion, wherein the distal portion comprises a plurality of segments that articulate with respect to one another; and a handle attached to the proximal portion of the shaft, wherein the handle comprises controls for articulating the plurality of segments of the distal portion of the shaft with respect to one another. A system for dissecting tissue and or guiding a medical device to a desired physiological location.
Abstract:
A process to prepare an olefin from its corresponding alcohol is improved by reacting, under reaction conditions including a first temperature, an aliphatic alcohol and, optionally, diluent water, to form a reaction product including at least a dialkyl ether. The product is then reacted again, under higher temperature to complete the dehydration of the dialkyl ether to the desired olefin. This process is particularly suitable to prepare ethene from ethyl alcohol. The stepped temperature scheme serves to reduce the formation of byproduct aldehydes, which in turn reduces coke formation, fouling, and the need to handle large amounts of water, thereby lowering energy and capital costs.
