Title: Method of testing telephone subscriber's lines
Inventor: GOODMAN DAVID MICHAEL
IPC: H04M3/30
Filed: 1985-04-18
Abstract: To test the attenuation of a telephone subscriber's line two measurements are made with the telephone on hook, one at a relatively low frequency and the other at a relatively high frequency. The frequencies chosen in one case are 900 Hz and 3 KHz. To do this a signal generator (SG) with a known internal impedance, e.g. 600 ohms, is connected to the line wires (LW1 and LW2), and the voltage ratio Vo/Vs determined. The two ratios thus obtained, plus a knowledge of the internal resistance of the generator, give a good assessment of the line's impedance characteristics. <IMAGE>

A funnel-shaped storage chamber (7) is located above the fluidization chamber and does successively replace consumed material.
Patent GB-2179517-A (GB)
Title: Wideband optical link
Inventor: BUTTERFIELD EDWARD BRIAN
IPC: H04B10/54
Filed: 1985-08-15
Abstract: A wideband optical link, e.g. for 8 TV channels or a block of stereo audio channels uses a highly linear VCOO (1) to which the multiplex input signal is applied. The VCO output is applied to a mixer (2) where it is mixed with the signal from an oscillator (3). The mixer output goes to a filter (4) which passes the desired mixer's sideband, in this case the lower sideband, and this, via amplifiers (5) and limiter (6) controls the laser (7) whose output is applied to an optical fibre. Thus the highly linear VCO enables a laser of relatively poor linearity to be used. At the receiver (Fig. 2) the signal from an optical receiver (10) goes via a filter (11) to another mixer (12), whose output is filtered (14) to pass the desired mixer side band. This then goes via a differential demodulator (15-16-17) to an output filter (18), the output of which is the receiver's output. <IMAGE>

Title: Traffic light control system
Inventor: LUX LAURENCE JOHN
IPC: G08G1/08
Filed: 1985-09-25
Abstract: A traffic light control system has two signal heads with associated detectors to sense approaching vehicles. A common control unit (1) has a setting-knob (2) which is turned to a distance mark on a scale (4) corresponding to the actual distance between signal heads. This sets a mandatory all-red period and a maximum green period for each head. Traffic flow may extend a minimum green period up to this limit. If this maximum is obtained a number of times in succession, it is extended to a new maximum, and similarly beyond that to a further maximum. When these new limits are not met, there is reversion to the previous maximum. The all-red period is not affected. <IMAGE>

Title: Holographic analogue indicating means
Inventor: ROBINSON ANTHONY JOHN BENBOW
IPC: G01D13/02
Filed: 1985-12-02
Abstract: In an analogue indicating device (e.g. a clock) in which the relative positions of two relatively movable components (26/28 and 12) is judged by the position of a reference marker (30/32) on one of the components (26/28) in relation to an adjacent scale (48) on the other component (12), the scale is constituted by a hologram (in 12) which when illuminated by a predetermined reference light (33) portrays a desired image of the scale (48) against which the reference marker (26/28) is seen. That image may also portray an environment (34) (e.g. a clock case) in which the scale (48) appears to be contained. The reference marker (26/28) may also be constituted by a hologram for portraying a holographic image of the reference marker. Alternatively, a holographically portrayed reference marker may cooperate with a real scale. The holographically produced image is preferably copolanar with the other image so as to elliminate parallax errors. The use of the invention in relation to time-keeping devices (Figs. 1-3), electrical indicating instruments (Figs. 4-5), dimension measuring devices including a rule (Figs. 16-21 and 28-31), and operating mode adjusters (Figs. 14, 15, 22, 23) and selectors (Figs. 24-27) is described. <IMAGE>

Title: Improvements in or relating to switch latches
Inventor: WESSLING WILHELM
IPC: H01H5/00
Filed: 1985-12-06
Abstract: The closing speed of the contacts in, e.g. an earth-leakage circuit breaker is increased by means of a latching arrangement. Member (3) bearing the moving contact is clockwise rotatable by means of a manually operable switch knob and is connected via linkages (5) and (7) to a shaft (8) bearing a disc (9) which rollingly engages a spring-loaded locking element (13). The locking element (13) holds the shaft (8) in such a.position that the full clockwise rotation of member (3) is prevented and the contacts remain open. As increasing force is applied to the switch knob energy is stored in the operator's hand and in "play" and elastic deformation in the system. When a selectable surmounting force is reached, the locking element (13) is swung back against the spring and the disc (9) rolls out of engagement therewith, the stored energy ensuring rapid completion of closing of the contacts. <IMAGE>
