Title: Electrical shuttered socket and plug
Inventor: HARRISON DAVID CHARLES PETER
IPC: H01R13/453
Filed: 1998-10-01
Abstract: An electrical plug is provided with a number of phase pins (44, 48 and 50) and a pair of key pegs (52, 54) which enable the plug to be used in a non-standard socket. The socket has apertures (6 and 8) for receiving the phase pins of the plug, and further apertures (12 and 14) for receiving the key pegs. These apertures are selectively blocked by means of a shutter (3). The shutter is movable from a closed position, in which at least the aperture for the live pin is blocked, into an open position, in which the socket is able to receive the pins and key pegs of the plug. The arrangement is such that the insertion of a pin or peg (other than the live phase pin) into its respective aperture partially opens a shutter so as to enable movement into the open position to be completed by the insertion of another of the pins or pegs (other than the live pin) into its aperture. Thus, access to the live contact (behind the corresponding aperture in the socket) is prevented unless two protuberances are inserted into other apertures in the socket.

Filed: 1998-12-09
Abstract: An apparatus connects to a legacy host computer system of the type having a non-hierarchical file structure for controlling simultaneous communication between it and local processing devices. Provided that the server is awaiting requests, a data retrieval request from a local processor is detected 3 on a preset communications port, and a check is made 4 to determine whether a pool session is available from a queue QA. If a session is available the request is assigned 6 to that session. The server reads 7 the data stream associated with the request, and parses 8 the stream. Connection details are extracted 9 from the requests, and it is determined 10 if the request forms part of an existing conversation. The apparatus improves the efficiency and transparency of communications between computer systems to release legacy based host information for Internet and Intranet technologies. The method and apparatus described use remain connected headers, size adjustable multiplexed memory blocks and pool sessions to optimise use of system resources and make the information available.
