Title: Adjustable-programme time switch
IPC: G04C23/02
Filed: 1971-11-11
Abstract: 1372273 Time switches DANFOSS AS 11 Nov 1971 [16 Nov 1970] 52422/71 Heading H1N An adjustable-programme time switch having a rotating timing disc has a readily removable programme disc fitted on the rear of the timing disc for rotation therewith wherein the annular zone adjacent the circumference of the programme disc can be readily provided with gaps extending from the circumference by removal of portions of the programme disc such that contacts are controlled in dependence upon the said gaps. As shown, a timing mechanism 3 has a gear 4 coupled (Fig. 3, not shown) to a gear 12 which drives a backing disc 14 via a one-way slipping clutch spring 13. Disc 14 is carried on a journal 5 fixed to base frame 1 and has a hub 16 on which a programme disc 17 and a time disc 18 are secured by a nut 19. A pin 20 ensures angular correlation of discs 14, 17, and 18. Disc 18 comprises a metal disc 22 and a transparent disc 23, one of which carries the time scale 36. Nut 19 permits removal of disc 18 for alteration of programme disc 17, which is made of a material such as polystyrene which can be readily cut for removal of portions of its outer annular zone to provide gaps 33 which enable contacts 10 and 11 to engage the metal disc 22. Disc 17 is of smaller radius than disc 22 such that a contact 9 is in continuous engagement with the disc 22. The contacts 10 and 11 may be offset circumferentially (Fig. 4, not shown) to make and break a circuit via contact 9 at different times, or the programme disc 17 may be cut away for different angular extents (35) at the corresponding radii. The metal disc 22 provides an annular window 38, with only thin webs 39 holding the outer portion, and the gaps 33 can be seen therethrough. The front face of disc 14 is contrastingly coloured, e.g., black, and is visible through the opening 38 and gaps 33. The programme disc 17 is provided with time scales (28, 29, Fig. 4, not shown) in hours and days of the week, corresponding to the scales 36, and has radial lines at hourly spacing to assist in creating gaps of the desired length; it is of reduced thickness along a circular line (30) such that a portion may be easily broken off after making two radial cuts.

Title: Taximeters
IPC: G07B13/08
Filed: 1971-11-19
Abstract: 1372869 Electronic taximeter GEECEN Ltd 30 June 1972 [19 Nov 1971] 53962/71 Heading G4T  In an electronic taximeter, time and/or distance pulses are fed at 12 to a counter 13-16, an arrangement of gates 23-26 determines the number of input pulses to the counter necessary to produce an output pulse from a gate 40, the output pulse resets the counter and triggers a circuit 42-44 to pass a predetermined number of pulses from line 38 via line 39 to a fare indicator, the output pulse from 40 also operates a counter 45/46 which in turn sequentially energizes control circuits 48, 49, &c. (only two shown) at predetermined values of time and/or distance, the circuits 48, 49, &c. controlling the gates 23-26 to effect automatic tariff changes. Binary coded outputs from the four denominations of the counter 13-16 are fed to respective decoders 18-21, each of which has ten outputs, each applied to a gate 23, 24, 25 or 26 (only some of which are shown). At any particular time, four selected gates, one from each group of ten, are enabled by signals over lines 28-31 from the control circuit 48, 49, &c. energized at that time. When the count reaches the value associated with these four gates, each of the four delivers a pulse to AND 40, which therefore emits an output pulse. During the "initial hire" period (minimum fare), the output signals are blocked by circuit 41 from triggering circuit 42-44. When the count of output pulses in counter 45/46 corresponds to the end of the "initial hire" period, an output from the counter 45/46 to AND 60 disables the blocking circuit 41. Each control circuit 48, 49, &c. includes AND gates 50, 51 connected to the counter 45/46 and opened when predetermined values (corresponding to desired tariff changeover points) are reached by counter 45/46. AND 52 then gives an output which, through latch circuit 55 enables the corresponding gates 23-26. The output from each AND 52 is also applied as an input to the AND 52 of the next control circuit to ensure the desired sequence of tariffs; the output from AND 52 of the last or nth control circuit is applied as an input to AND 52 of the first control circuit 48.  The end of the "initial hire" period, instead of being registered by counter 45/46, AND 60 and blocking circuit 41, may be registered by one of the circuits 48, 49, &c.

Abstract: 1,271,280. Electro mechanically controlled lock mechanism. STANDARD TELEPHONES & CABLES Ltd. 25 Nov., 1969, No. 57625/69. Heading E2A. An electromechanically controlled lock mechanism including a bolt 3, a locking plunger 11 arranged when the bolt is shot to interlock with the belt and hold it in position, a belt-driving member 22, a link pin 18, mounted on the bolt for coupling the boltdriving member 22 to the bolt 3, a mechanical linkage 14 coupling the locking plunger 11 to the link pin 18 in such manner that as the plunger is disengaged from the bolt the link pin interlocks with the bolt-driving member 22, and vice versa, the arrangement being spring loaded by 19 to urge the plunger to interlock with the bolt, and a magnetic solenoid 21 arranged when energised to withdraw the plunger from the bolt.  In moving from the locking position shown in Fig. 2, a permutation mechanism 25 of rotary switches described in detail in Specification 1,271,279 is aligned to make electrical contact by rotation of the operating knob (6) on the shaft 30 on which there is mounted a cam 27 connected to the bolt driving member 22. At this point the middle of the slot 23 in the bolt driving member 22 is adjacent the link pin 18 with the driving bolt 22-moving to the right in Fig. 2 by the manual operation of knob (6). When the left hand side of the slot 23 is adjacent the link pin 18 the switch 26 is closed, activating the solenoid 21 which raises the plunger 11 out of the slot 12 and thus through the pivoted linkage 14, forces the link pin 18 against the spring 19 into the slot 23 and thus the bolt 3 is thereafter withdrawn with the rightward further movement of the bolt driving mechanism. As soon as the plunger 11 is clear of the slot 12 the switch 26 is opened and the plunger 11 falls on to the top 28 of the bolt 3, the link pin 18, still engaging the slot 23. When the bolt is fully withdrawn the stop 9 is engaged by the edge of the bearing 8. On returning to the locked position the slot 23 provides lost motion so that the solenoid 21 is not activated when the plunger 11 is aligned with the slot 12.
