Title: >Circuit for security fences
Inventor: SPEEDY JOHN OLIVER
IPC: G08B13/16
Filed: 1982-12-20
Abstract: An electrical monitoring system for a security fence includes in a network a number of normally closed vibrating inertia intruder switches 10. Each switch is provided with a shorting resistor 12. When the switches 10 open intermittently monitoring signals passing along the network are influenced by the opening and closing of the switches 10 and suitable alarm signals can be generated. If the resistors 12 are not present and one of the switches 10 remains open due to faulty operation the whole network becomes unserviceable. With the present arrangement this is not the case and in one specific embodiment up to three faulty switches can be tolerated. <IMAGE>

Title: Saturable transformer
Inventor: CROSS PETER
IPC: H01F29/14
Filed: 1982-12-24
Abstract: A saturable transformer has first and second windings (16, 18) wound on first and second parts (17, 19) of a magnetic core. A control winding (15), also wound on the core, is energisable to bring about saturation of the second core part (19) whereby to destroy transformer action between the first and second windings (16, 18). The construction of the transformer is such that energisation of the control winding (15) does not cause saturation of the first core part (17); as a result, the impedance of the first winding (16) is not drastically reduced upon control winding energisation. The saturable transformer find application in apparatus for automatically bringing into operation a standby filament (21) of a multifilament lamp unit upon failure of the main lamp (20); in this application, the first and second windings (16, 18) are respectively connected to an a.c. energisation source (22) and to the standby filament (21), while the control winding (15) is arranged to be energised only for as long as current continues to flow through the main filament (20). <IMAGE>

Patent GB-2172845-A (GB)
Title: Method for joining polyolefin pipes by fusion
Inventor: STAFFORD TREVOR GEORGE
IPC: B29C65/24
Filed: 1986-01-06
Abstract: The apparatus increases the hydraulic pressure in rams 16 until one pipe moves towards a heater plate 14. The movement is detected by a limit switch 26 and a microprocessor-based control system 28 adds a pre-programmed value of pressure to that pressure which caused the movement (drag pressure). The total pressure is applied to force the pipe ends against a heater plate 14 to form end beads (bead-up). After heating for a pre-programmed period the control system automatically initiates plate retraction and forces the pipe ends together (fusion) for another programmed period. The applied pressure is the sum of the recorded drag pressure and a pre-programmed added pressure. Operator judgement of bead size, pressures and time periods is eliminated. Pressurised fluid is supplied to the rams 16 from a pump and accumulator combination. The sense of ram motion is determined by changeover valves controlled by the control system 28.
