Abstract: A measurement system for measuring the time for a signal to pass between two transducers TDR1,2 to allow fluid speed or flow to be determined in a gas meter for example. Each transducer can transmit or receive signals. The system is controlled by a microcontroller 31 and a signal with a phase change acts as a marker which is transmitted from transmitter 21 via matching stage 22,23 from one transducer and is received by the other. On receipt via the matching stage and amplifier 24 it is sampled by capacitor array 25 and detected in detector 29. Amplitude information from array 25 is made available to the microcontroller to compute time of signal travel and hence flow rates.

Abstract: A high speed data packet switching circuit has a software controlled primary processing unit (12), a plurality of network interface units (40a-40n) connected to a plurality of networks for receiving incoming data packet streams and for transmitting outgoing data packet streams, a plurality of high speed data stream hardware control circuits (14a-14p) for processing data packets in response to instructions from the primary processing unit (12) and circuitry for interconnecting the primary processing unit (12), the interface units (40a-40n), and the data stream control circuits (14a-14p). The primary processing unit (12), receives from the network interface unit (40a-40n) at least a first one of the data packets of each new data packet stream and assigns that stream to be processed by one of the data stream control circuits (14a-14p) without further processing by the primary processing unit (12). The apparatus and method thus perform routine, repetitive processing steps on the further packets of the data stream using the high speed hardware (14a-14p), while the initial processing and other non-repetitive or special processing of the data packets are performed in software. Particular hardware is described for effecting the high speed hardware processing of the data packets.

Abstract: A safety sealing device includes a support. An electronic safety circuit is glued to one face of the support. The electronic safety circuit includes a winding of fine wire connected to an electronic component. The electronic component is activated and interrogated by outside checking means via the winding, which acts as an antenna. The electronic component may be coded so that it responds to the interrogation with its code. The safety sealing device may further comprise differentiated gluing means. When attempting to tamper with the support to which the safety circuit has been glued in order to unseal a receiving article, the attempt at ungluing or a tearing causes a break in the continuity of the electronic circuit. As a result, the electronic component no longer responds to an interrogation with its code, thus assuredly indicating that the safety sealing device has been tampered with.

Abstract: A method and apparatus for penetrating a well casing and surrounding earth strata includes the insertion of a flexible shaft having a ball cutter on an end thereof into upset tubing within a well casing. The upset tubing is provided with an elbow at its lower extremity for receiving the ball cutter therein. The flexible shaft is then rotated and the ball cutter cuts a hole in the well casing and is then moved horizontally a distance, usually less than 30''. The flexible shaft and ball cutter are then removed and a flexible tube having a nozzle blaster on an end thereof is then inserted into the upset tubing in the channel. A fluid of surfactant and water at high pressure is then pumped into the tube wherein the high pressure fluid passes through orifice in the spiral drill thereby cutting an extension into the previously cut channel. The tube is continually feed into the channel as the high pressure fluid continues to blast away the earth's strata. The channel is then cut a preselected distance from the well up to 200 feet and beyond.
