Title: Detector apparatus for obtaining road traffic information
IPC: G01V3/10
Filed: 1969-11-18
Abstract: 1,245,360. Road traffic detectors. OMRON TATEISI ELECTRONICS CO. 18 Nov., 1969 [29 Nov., 1968; 12 Dec., 1968], No. 56407/69. Heading G4Q. A detector comprises a composite inductance loop 1 consisting of a large loop portion 1A and a small loop portion 1B connected in series. The large loop extends for a considerable distance, L, e.g. 50-150 metres, along the road R, whereas the small loop has a length l of, e.g., 1-2 metres. A vehicle travelling from E to G generates a large signal B1 when in the loop portion 1B and a small signal B3 when leaving the loop portion 1A, Fig. 2, this difference in signal magnitude resulting from the portion 1B having more turns than the portion 1A. Whilst the vehicle travels between F and G, a constant signal B2 between the levels B1, B3 is generated. The detector 4 produces a corresponding output shown in Fig. 3. A number of vehicles continually entering at E and proceeding to the exit G cause the signal level H1 to become progressively higher in increments of H2, each succeeding vehicle producing a peak PM1, PM2 &c., Fig. 4. If the differentiating amplifier 5 fed by detector 4 is set to operate at level H1 or above, each peak of Fig. 4 will cause operation of counter 6 and by counting the pulses over a given period of time the traffic volume may be calculated. By measuring the magnitude of the signal of detector 4, the number of vehicles within the space E to G are signified and hence the traffic density may be calculated. To obtain the speed of an individual vehicle the amplifier is set to be operated by both levels H1 and H3. Thus by detecting both these levels on the counter 6 and by measuring the time interval between them, the vehicle speed may be calculated. A compensation arrangement for nulling the effects of temperature and moisture is described with reference to Figs. 6, 7 (not shown), this arrangement functioning either automatically or by manual control.

Abstract: 1,166,507. Indicators for switches. SWFSPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU G.m.b.H. 19 Dec., 1966 [9 May, 1966], No. 56609/66. Heading H1N.  A switch indicator arrangement comprises a lamp and light-conducting or marking means which move with the switch actuator to vary the amount of light reaching the activator in its two positions. In one form, Fig. 1, several translucent or transparent push-buttons 2 have light-conducting rods 5 the ends of which extend into a lamp space 8. When a switch is " off ", only the tip 12 of the rod transmits light, but when " on ", a larger portion 11 transmits a greater amount of light. The actuators may be rockers, and in one form (Fig. 2, not shown), the rocker moves a light-conducting rod (112) having a blackened portion (113) which reduces the illumination when the switch is " off ". The rocker may contain a pivoted mark with large and small apertures (Fig. 4, not shown). A springy or sliding mark may be moved by the rocker (Figs. 6, 7, not shown).
