Patent GB-2208192-A (GB)
Title: Back-up power supply
Inventor: COWAN ROBERT THOMAS
IPC: H02J9/06
Filed: 1988-07-07
Abstract: Electronic equipment 12, particularly a computer is energised by a battery 40 via a diode 42 in the event of failure of a mains-derived supply 22, 24, and means 106 and 130 are provided respectively to indicate the mains supply status and a low energy level in battery 40. A transformer 44 and rectifier 52 provide a supply to energise relays, 60, 62, 64 and to charge an auxiliary battery 74 operable to energise the monitoring and indicating circuits. Relays 60, 62, 64 respectively have normally open contacts 60-1, 60-2, normally closed contacts 62-1, 62-2, and changeover contacts 64-1, whereby LED devices 106 and 130 both normally give a steady green light respectively indicating pressure of the mains supply and closure of a standby switch 50. If the mains supply fails, device 106 gives a flashing red light, a sounder 116 is energised, and contacts 62-2 close to connect the backup battery 40 to a comparator which cause device 130 to give a steady green light if the battery voltage is above a reference. If the voltage of a battery 40 is below the reference, device 130 gives a flashing red light and a sounder 140 is energised. A trickle charging supply may be provided for battery 40 if it is rechargeable. The relays may be replaced by solid state devices. Equipment 12 may have a switched mode supply maintaining a substantially constant power drain with in variation in the supply voltage. <IMAGE>

Title: Passive quadrature phase detection system for coherent fiber optic systems
Inventor: KIM BYOUNG Y
IPC: H04B10/2581
Filed: 1990-07-31
Abstract: A passive quadrature phase detection system for coherent fiber systems includes first and second optical detectors (882, 884; 892, 894) positioned to receive an output signal (852, 982) from the output end (846, 980) of an optical signal apparatus such as an interferometer (800), or homodyne receiver (950). The optical signal (852, 982) from the apparatus includes light propagating in two propagation modes. As the light propagates away from the output end (846, 980) of the apparatus from the near field to the far field, the light in the two modes undergoes a relative phase shift of  pi /2 in accordance with the Guoy effect. The two detectors (882, 884; 892, 894) are positioned such that the first detector (882, 884) detects the intensity of light resulting from the interference between the two modes in the near field of the output signal, and such that the second detector (892, 894) does the same for the far field. The additional  pi /2 phase difference introduced between the two modes as the light propagates from the near field light to the far field causes the detected light intensities to be in phase quadrature. Electrical signals (cos o, sin o) proportional to the detected light intensities can be processed to determine changes in the phase difference between the two modes within the apparatus. In preferred embodiments, the detection of the near field light intensity is accomplished at a position optically displaced from the output end (846, 980) of the apparatus. <IMAGE>

The high pass filter 12-5 is preferably a capacitor having an impedance much greater than that of coil 12-4 in the noise frequency region and much less than that of coil 12-4 in the signal frequency region. <IMAGE>

Title: Self-plugging blind rivet
Inventor: BROWNE LAURENCE ANTHONY
IPC: F16B19/10
Filed: 1991-10-09
Abstract: A self-plugging blind rivet 10 comprises a tubular body 14 having a preformed head 34 at one end, and in the bore 36 of which a headed stem 12 is disposed. The stem 12 projects from the head 34 end of the body 14, and the head 18 of the stem 12 is substantially enclosed by a region 42 of the body 14 remote from the preformed head 34. The head 18 of the stem 12 abuts a shoulder 44 provided by a region 43 of the body 14 in which the diameter of the bore 36 is reduced and the wall is thickened. Axially spaced apart annular grooves 46, 48 in the external surface of the body 14 define between them a portion 50 which will collapse to form a blind head when the body 14 is compressed axially by pulling the stem 12 while supporting the preformed head 34. Finally, the stem head 18 may be pulled into the reduced diameter region 40 of the bore 36 and thereby cause the blind head to be reshaped and forced into compressive engagement with work being fastened. The stem head 18 remains securely enclosed by the body 14, whereby its loss is prevented. <IMAGE>
