Filed: 1974-11-20
Abstract: 1474189 Vehicle counters M J DALGLEISH 20 Nov 1974 [23 Nov 1973] 54526/73 Heading G4D A roadside vehicle counter or the like comprises a counter 13 receiving pulses, from a pneumatic road tube or electromagnetic detector for instance, at random times and a timer 3-7 which at preselected intervals causes the instantaneous count to be loaded in parallel into a shift register 14 and thereafter to be readout serially to a tape recorder and the counter to be reset. The timer divides down from a 2À2 MHz crystal controlled oscillator to provide a count of minutes, hours and days in a b.c.d. counter 7. Every 10, 20, 30 or 60 minutes, for example, a selector 11 releases a "write" pulse on line 37; this triggers a monostable 16 causing a tape recorder to run for 2 seconds. The tape recorder may be a standard cassette type, the monostable 16 acting through a relay on the start contacts of the microphone socket. Simultaneously the "write" pulse cause the vehicle and time counts to be loaded into shift register stages 14, 8; an all ones signal is also loaded into stages 15 and an end code into stages 10 of the register. After 1 second a monostable 19 releases a counter 20 which issues sufficient pulses to read-out all stages of the shift register to a gate 21; whenever a "1" state is applied to gate 21 it triggers a 4 m.sec. monostable and when a "0" state is applied, a 2 m.sec. monostable. The monostables 22 control an oscillator 24 so as to release 4 msec. and 2 m.sec. bursts of a 5 kHz tone to be recorded on the tape. The time, date and count as selected by switch 43 can be read on a liquid crystal display 26. A read-out to the tape can be forced at any time or prevented by signals at 34, 35 respectively. The selector 11 may be arranged to vary the period between read-outs according to the time of day or week. Using for instance a light level detector (not shown) the shift register 8 may also receive details of weather conditions &c. The input to the counter 13 from the road tube may be by a pneumatic switch or a crystal microphone the signal being squared up at 1 and divided by 2 to convert the number of axles to vehicles. The Specification describes detailed logic circuits; low power CMOS integrated circuits are suggested. In a system (Fig. 5, not shown) for reading the tape the tone bursts are interpreted as 0's and l's and inserted serially into a shift register and read-out in parallel to a display. The system is started by a pushbutton or computer signal and stopped when the end code is detected. The all l's signal (from stages 15) is sensed and if a "0" is detected a fault alarm is energized.

The transfer cut-out lever 71 of any denomination except the lowest is operated by key 81 and has its movement limited by the engagement of notch 82 with cross-shaft 83. The. lever is shown in its normal inoperative position with. pin 84 on the top of arm 85 of the three-armed lever 72 connected to lever 71 by spring 91. With the mechanism as shown, transfer takes place when cam 46, in known manner, swings lever 48 clockwise to advance gear 31 through pawl 49. When key 81 is pressed forward, lever 72 rocks clockwise to latch lever 71 by the engagement of pin 84 against the end of arm 85. The tail of lever 71 rocks pawls 49 counter-clockwise into inoperative position and when lever 48 swings clockwise, no transfer takes place, but wing 94 at the top of lever 48 strikes arm 87 to release latching lever 72. If no transfer attempt takes place, lever 71 can be restored manually by applying sufficient pressure to key 81, pin 84 camming arm 85 against the action of spring 91. Even if no transfer attempt takes place, lever 71 is restored whenever the accumulator 36 is zeroized, when plates 64 are rocked counter-clockwise about shaft 35, in known manner, and rock lever 73 so that nose 103 presses against arm 88 to release latch 72. In known manner, plates 64 remain in this position to prevent relatching of lever 71 until a new entry has been made. Flange 105 on arm 88 is normally invisible but becomes visible when latch 72 is operative.
