Title: Error detecting apparatus
IPC: G08C25/00
Filed: 1972-01-12
Abstract: 1350555 Selective signalling SIEMENS AG 12 Jan 1972 [12 Jan 1971] 1526/72 Heading G4H Apparatus for selecting the group of signals having the fewest errors from nominally identical groups of signals includes means for detecting and counting the errors occurring in each group in turn and storage means 7 which stores that group of signals having fewer errors than any one of the groups whose errors have previously been detected and counted. Groups of twelve signals in (2/5) code are input at 5 to stores 51, 53 and to a circuit 54 which feeds an error signal 11111 to an OR-gate 55 whenever a signal does not have exactly two l's, gate 55 also receiving this error signal if corresponding signals in any two successive groups are not found by a comparator 52 to be the same: in either case the faulty signal is replaced in 53 by the error signal and a counter 6 is incremented. An AND-gate 56 is enabled whenever the group then in 53 contains fewer errors than a group already in store 7, this latter group having been checked for errors by a circuit 71 and a second counter 8 correspondingly incremented: the counts from 6 and 8 are fed to a comparator 62 which sets a flip-flop 61 if count (6) < count (8) on the occurrence of a clock pulse N2 (counter 8 is initially set at its maximum value so that the first signal group may pass through gate 56). After each signal group has been tested to see whether it is a new fewest-errors group (and, if so, allowed to replace the previous group in 7), a pulse N3 resets counters 6 and 8 (if 61 has been set), then a pulse N1 resets 61. Whenever count (6) is a maximum its output 601 increments a control counter 9 via an AND-gate 92 which is enabled if count (8) has not exceeded a maximum error level set on switches 82. Counter 9 is reset by N2 if count (6) is not at that moment a maximum; if it is, then count (9) continues to increase until it reaches a preset level, whereupon its output 901 effects the transfer from store 7 of the final fewest-error group.

Abstract: 523,979. Ohmmeters ; combinations of instruments. MACADIE, H. S., FRAENKEL, H., and AUTOMATIC COIL WINDER & ELECTRICAL EQUIPMENT CO., Ltd. Jan. 18, 1939, No. 1742. [Class 37] In a multi-range ohmmeter the ranges overlap so that any resistance from one ohm or less to ten megohms or more may be measured. On the high range the current coil 13, Fig. 5, of the crossed coil moving coil system 13, 14 is connected through a resistance 12 to one terminal 10 for connection to the resistance to be measured, the junction of the coils 13, 14 being connected to one lead 15 of a high voltage supplied by a buzzer rectifier 16 fed by two low-voltage batteries 17, 18 in series. The other terminal lead 20 of the buzzer rectifier 16 is connected through a resistance A to the other terminal 11 connected to the resistance under test. The pressure coil 14 is connected across the high voltage supply in series with a resistance B. .These connections are made in position I of the switch shown in Fig. 6, by connecting contacts 1, 2 and a, b. In the second position II of the switch, giving the higher intermediate range, contacts a, b are broken and contacts 7,8, b joined, so that the resistances A, B are reduced and the high voltage supply is replaced by the low voltage battery 18. In position III of the switch giving the lower intermediate range the series resistance A is further reduced by joining contacts 6, 8 b and the current coil 13 is shunted by a resistance 23 by joining contacts 1, 2, 4. In the low range position IV contacts 1, 5 are joined, also contacts 2, 3 and 8, 9, b, so that the unknown resistance across the terminals 10, 11 is in parallel with the current coil 13 and its series resistance 12. Two pairs of contacts 41, 42 are operated by a common push-button. The switch, Fig. 6, may comprise a rotary drum carrying longitudinal shorting strips co-operating with tangential spring contact blades and may have one or more metal guard rings or strips separating the shorting strips and contacts and indicated at 150, Fig. 5. The resistances and tappings may be so chosen that a single scale may be employed for the high and intermediate ranges, a separate scale being required for the low range. The operating knob of the range changing switch is provided with a pointer which indicates the scale to be used and the value of the unit on the scale. A voltmeter 50 as described in Specification 523,978 may be connected as shown. According to the Provisional Specification the ohmmeter may include the pole-piece structure described in Specification 523,980.

Abstract: 929,843. Parking meters. BLOCTUBE CONTROLS Ltd. April 17, 1962 [Jan. 18, 1961], No. 2039/61. Class 27. A parking meter, such as that described in Specification 775,509, has means for temporarily holding an undersize coin without it actuating the meter mechanism and for releasing it on insertion of a further coin so that the user of the meter can reclaim the undersized coin. An inserted coin, after actuating bell-cranks 44, 46, comes to rest on a stop finger 78 and, if of correct size, sets a lever 103 so that the complete cycle of the mechanism can take place. During the latter part of the cycle, the finger 78 is withdrawn and the coin falls to a member 13 where it remains until a further coin is inserted and causes withdrawal of the member 13 so that the coin falls to a coin box. An undersize coin, such as a two-shilling piece, resting on the finger 78 fails to set the lever 103 correctly for operation of the meter but when a further coin, say a half-crown is inserted, the crank 44 opens a door 110 and an ejection member 121 on the door pushes the undersize coin into a V-shaped trough 1 leading to an outlet 2. A spring-loaded flap 3 closes the outlet and has an arm 4 which, on raising of the flap, propels the coin through the outlet.
