Patent GB-2140991-A (GB)
Title: Emergency supply for fluorescent tube
Inventor: NORLYK HOLGER
IPC: H02J9/06
Filed: 1984-05-21
Abstract: The tube LR is normally powered from the mains supply 2, 3 via a reactor RE, and in the event of mains failure the tube is supplied from a battery powered high frequency oscillator OSC coupled via a winding L3 of a transformer TR1 to a winding L5 connected between a starter GL and a filament G1 of the tube. A capacitor C5 has a high impedance at mains frequency and a lower impedance at the oscillator frequency, the oscillator producing voltage transients so that the tube LR will start even with cold filaments G1, G2. An electromechanical or electronic relay turns the oscillator OSC off if the mains supply is present. Alternatively, the battery charging current may saturate a transformer (TR2), (Fig. 2), in oscillator OSC and also establish a voltage drop to hold a transistor (T1) in the oscillator OSC blocked when the mains supply is present. The transformer TR1 has a further winding L4 having the same number of turns as winding L5 so that when the oscillator is operating points 4 and 5 are at the same potential, whereby if the switch S is closed there is no potential drop across the mains terminals 2, 3 so that the oscillator will not be loaded by any other load connected across 2, 3. The oscillator OSC includes a circuit (D2, C4, T2) to turn it off if excess voltage is produced, eg. if the tube LR is disconnected. <IMAGE>

Patent GB-2169765-A (GB)
Title: Optical amplifiers
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G02F1/39
Filed: 1985-11-15
Abstract: @ An optical signal pulse to be amplified and a pump signal pulse are launched consecutively into one end of an optical fibre, which may comprise a separate fibre or part of a transmission line. The pulses differ in wavelength by one or more Stokes shift and the order of launch is determined by the relevant group velocities in the fibre. Owing to dispersion in the fibre the pulses overlap and overtake one another while they are transmitted along the fibre, the signal pulse being amplified as a result of Raman stimulated emission and compressed as a result of power depletion from the pump pulse, thus increasing the bandwidth of the transmission line.

Title: Magnetoresistive sensors
Inventor: MAPPS DESMOND JAMES
IPC: G01R33/09
Filed: 1985-11-25
Abstract: A thin-film magnetoresistive sensor for detecting and/or measuring magnetic fields, e.g. from a track (12), has enhanced shape anisotopy in a direction (y) transversely to its longitudinal axis (x) by the use of a finned configuration (24) for the film (16). The fins (24) act as an integral flux guide from the track (12) to the main stripe (20) of the film positioned some distance from the track. The fins (24) may have alternative shapes (Figs. 4-7). Particularly preferred are fins broader in the x-direction adjacent to the track than they are adjacent to the main stripe, thereby to funnel flux away from the track (Fig. 7). The sensors have, for example, increased high frequency end bandwidth, increased transverse sensitivity, and burn-out current is higher. Tape, disc and credit card applications are specified. <IMAGE>
