Title: Pulse train generating and selection apparatus
IPC: H04M1/57
Filed: 1971-06-02
Abstract: 1362412 Substation equipment T PARASKEVAKOS 2 June 1971 23923/71 Heading H4K Data characteristic of a calling line in a telecommunications exchange is obtained from a common pulse generator means, which produces a plurality of pulse trains each train representing one item of said data, by further means including selection units associated with the respective calling lines and operable to automatically select a particular sequence of said pulse trains which characterizes that unit and thus the associated calling line. In the system shown a pulse generator 12 consisting of twelve stages of bi-stable flip-flops which are switched by the output of clock pulses 16 to produce trains of pulses equal to the numbers shown on the output terminals, e.g. 12 pulses on terminal 12, 11 on 11 and so on. The clock pulse after the pulse on terminal 1 provides an end cycle and reset pulse on lines 32, 34 and may provide a further starting pulse on line 22. The pulses are transmitted on line 48 and can operate a recorder at the particular called substation so that the number of the calling party is recorded at times when the called substation is unanswered or engaged. The particular number of pulses to be transmitted for each digit is determined by the selection unit comprising binary digital counter 18 and priority unit 20 which consist of bi-stable flip-flops and an associated output gating circuit having the individual outputs energized corresponding to a particular state of the counter. These outputs are taken to a gate in the output units 46. The counter is progressed through its states by the clock 16 and is reset to a starting point by means of an enabling signal on line 26 which corresponds to the reset signal 24 so that it remains in step with pulse train generator 12. Each of the output units 46 has a unique arrangement of connections of lines 48 from generator 12 and 50 from priority unit 20 so that it will only respond to a set sequence of numbers. Additionally the unit 46 has to be enabled by control 42 which contains a bistable circuit which is set and reset by the presence of one of the unused states of counter 18 so that unit 46 is enabled for every second cycle of the number generator 12. Some of the digits sent may represent control information

Abstract: 1343155 Digital computers; interrupt HONEYWELL INFORMATION SYSTEMS Inc 19 April 1971 [29 April 1970] 24719/71 Heading G4A  An interrupt arrangement for a digital computer system is described. The system comprises a central processor 10, a core memory 14, a memory controller 18, an I/O multiplexer 22 and communication devices 26 (e.g. punched card readers and punches, magnetic tape and disc units, teletypewriter units, keyboard operated video display units operating in a time shared manner, or a unit for connection to another computer). Operation.-A device 26 notifies the multiplexer 22 of a desired interrupt (either conditional or unconditional) by means of a command word (Fig. 4). Bits 3-8 form the device number code, bits 1 and 15-17 indicate one of sixteen levels of interrupt, bits 5-8 indicate one of ; sixteen sub levels of interrupt, while bits 12-14 indicate the interrupt command.  The command word is decoded and bits 1 and 15-17 select one of 16 bi-stables in an interrupt level register (78, Fig. 2b, not shown). For each bi-stable there is a 16 bit word in memory (19, Fig. 2c, not shown) each bit indicating a different type of operation, and the corresponding word is read out to controller 18. In the word one (or more) bits is set using bits 5-8 of the command word and OR circuitry (87, Fig. 2b, not shown). The central processor (Fig. 2d, not shown) is notified of the interrupt and the interrupt having highest priority is determined. Firstly the 16 bi-stables are scanned to select the highest priority using a priority generator (99, Fig. 2b, not shown), then the highest priority bit in the corresponding word is selected using another priority generator (94, Fig. 2b, not shown). The controller 18 contains an address generator which generates an address of a vector word using signals indicating the highest priority bi-stable and the highest priority bit in the corresponding word. The vector word indicates the nature of the interruption which is then executed. If a 16 bit word in memory has more than one bit set, when the highest priority interrupt has been dealt with, just that one bit is reset, and the other bits are dealt with when they have highest priority.

Title: Faceted coin selection method and apparatus
Filed: 1972-05-25
Abstract: 1403103 Testing coins MARS Inc 25 May 1973 [25 May 1972] 24738/72 Heading G4V Apparatus for testing the anthenticity of faceted edge conductive coins comprises a coin track 30 along which coins roll, two electromagnetic sensors 60, 80, the primarily responsive regions of the sensors being located equidistantly above said track at a distance greater than the diameter of the inscribing circle of the coin and separated in a direction parallel to said track by a distance D substantially equal to an odd integral multiple of one half of the length of a facet and means for examining the signals produced by the sensors as the coin passes. In the embodiment shown the sensors comprise inductors having E-shaped metal cores 64, 64 and windings 62, 82 the primarily responsive regions of the sensors being the centre poles of the cores (see also Figs. 2, 3, not reproduced). The sensors are mounted on one side of a laterally inclined non-conductive side wall 40 against the other side of which the coins lean when rolling down the track. The height of the lower face of the centre pole of the core is approximately equal to the diameter of a circle circumscribing the coin and the spacing of the outer poles approximately equal to the length of one facet, the cores having cylindrical upper and lower surfaces generally concentric with a coin positioned between the inductor and the track. The inductances of the sensors on the passage of a genuine coin will lie in a range L 1  to L 2  (Figs. 4 to 6, not shown). A suitable intermediate value L INT  is chosen so that if the inductance of sensors lies in the range L 1  to L INT  the other inducatnce will be L INT  to L 2 . The inductors are connected to respective oscillators 70, 90 the frequencies of which will be changed to f 1 , f INT  or f 2 , for the respective values of the inductances L 1 , L INT  or L 2 . Two narrow band detectors are connected to each of the osisllators, the detectors 72, 92 being tuned to the range f 1  to f INT  and the detectors 74, 94 to the range f INT  to f 2 , each detector producing one or two pulses according to whether the frequency of the oscillator enters or passes through the corresponding range with flip-flops 76, 78, 96 and 98 being set or reset appropriately. AND gates 100, 102 and EXCLUSIVE OR gate 104 analyse the outputs of the flip-flops to determine whether the frequency of one oscillator has moved into but not through one of the ranges f 1  to f INT  or f INT  to f 2  and the frequency of the other oscillator has moved into but not through the other frequency range. In another embodiment (Fig. 8, not shown) only the detectors 72, 92 connected to a four stage counter (108) are used, a coin being deemed genuine if the frequency of one oscillator moves into the range f 1  to f INT  and the frequency of the other oscillator moves through this range.
