Title: Remotely controllable mounting for camera or tool
Inventor: YARNELL IAN ROLAND
IPC: B25J5/02
Filed: 1983-10-31
Abstract: Remotely controllable inspection apparatus intended for use in inaccessible, confined spaces such as sewer pipe interiors has an articulated arm (32) supporting a closed cicuit television camera (52) at its distal end. The arm (32) is pivotally mounted on a carriage (24) which is itself longitudinally slidable on a sledge (10). The arm (32) can be elevated about a first axis (34), a distal portion (54) of the arm (32) can be swung to one side or the other about a second axis (58), an outer part of the distal portion (54) is rotatable about a longitudinal axis (80), and the camera (52) can be swivelled on the end of the arm (32) about a transverse swivel axis (76). The range of movements provided allows the camera (52) to be positioned off-axis in a pipe and gives a remote operator the ability to inspect the wall of the pipe at close range and to view the interior of lateral branches where they join the pipe. The movement functions described above are all controlled hydraulically for reliability and resistance to immersion in water. <IMAGE>

Title: Intrusion detection barrier
Inventor: BEST DAVID
IPC: G08B13/26
Filed: 1985-02-22
Abstract: A plurality of pairs of wires 6 are arranged generally parallel to each other, preferably with each wire of a pair extending in opposite directions.

Patent GB-2177280-A (GB)
Title: Digital data transmission
Inventor: CHAMBERS JOHN PHILIP
IPC: H03M13/09
Filed: 1986-05-09
Abstract: Data in packets is transmitted with a continuity index to enable detection of a lost packet and with parity information to enable detection of errors within the packet. For transmission the continuity index and parity information are combined, e.g. by modulo-2 addition, so that at the receiver a correctly-received packet gives rise to a parity check output not of zero but indicating instead the continuity index. Departures from the continuity index sequence can be detected to indicate whether a packet has been lost or whether there is a single perturbation of the sequence indicating a parity error. By combining the continuity index and parity information for transmission a reduction in data rate can be obtained. <IMAGE>
