Title: Switch-condition-transmitting device
IPC: B60C23/04
Filed: 1974-11-06
Abstract: 1495148 Switch condition transmitting arrangement JAEGER 6 Nov 1974 [7 Nov 1973 28 June 1974] 48003/74 Heading H4L [Also in Division B7] In an arrangement for transmitting the condition of a switch 3 (which may be fitted in a tyre pressure sensing arrangement such that loss of pressure opens the switch), the switch when closed serially connects at least two coils 2 in a first assembly 1 which is in combination with a second relatively movable assembly incorporating a transmission coil 5 energized by a generator 31 and two serially connected detection coils 6a, 6b such that in one relative position of the assemblies, the transmission coil 5 and detections coils 6a, 6b are inductively coupled with respective coils 2. A detecting arrangement (operational amplifier 32) coupled to the serially connected detection coils produces different outputs depending on whether the detection coils are excited only by the transmission coil field (zero output) or whether they are also excited via the coils 2 of the first assembly (non zero output when switch 3 is closed). The output of amplifier 32 is applied to a control circuit 33 which operates an alarm if the switch opens and also to a counter 34 whose outputs control a decoder 35 which causes the transmission circuits for a number of switch condition transmitting arrangements to be operated in turn, e.g. to monitor the tyre pressures of a number of wheels, until a fault is detected. In an alternative embodiment (Fig. 12, not shown), the first assembly incorporates three coils in series with the switch 3, and the series connected detection coils of the second assembly are positioned one on either side of the transmission coil. The outputs from (n - 1) pairs of detector coils are applied in succession to the operational amplifier detector, and the output from this is compared with the output from the nth pair of detectors which is energized continuously by means of a storage and indicating arrangement (Fig. 8, not shown). In this the pulse outputs from the (n - 1) stages are applied to a storage capacitor (28) while the output from the reference stage is applied to a transistor (29R) in parallel with the capacitor which as a result alternately charges and discharges. However if the reference signal is missing, the charge builds up to operate a differential amplifier and thereby an alarm.

Title: Frequency Control in a Synthesizer of Very High Frequencies.
IPC: H03B21/02
Filed: 1968-10-10
Abstract: 1,196,859. Frequency synthesizers. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 10 Oct., 1968 [9 Nov., 1967], No. 48031/68. Headings H3A and H3F A frequency control device for a frequency synthesizer comprises a control box 40, Fig. 1, on which a desired frequency to be delivered by the synthesizer is registered, a modulator 13 connected to receive the frequency F to be controlled and also a wide step spectrum Fi having regularly spaced reference frequencies, a first low-pass filter 21 having a gradual cut-off extending within a region slightly lower than half the frequency spacing between two adjacent reference frequencies of the spectrum, and a second low-pass filter 23 having an effective cut-off frequency equal to the difference between half the frequency spacing between two adjacent reference frequencies of the spectrum and the cut-off frequency of the first low-pass filter. The two filters 21, 23 are connected to receive the output of the modulator 13, and a frequency divider 25 adapted to divide by two is connected in series with the second filter 21. The input of a counter 14 is switchable, by means of switch 30 between the output of filter 21 and the output of the divider 25, its output providing a check on whether the delivered synthesized frequency corresponds to that registered on the control box 40. As shown the filter 21 is followed by a threshold device only passing signals exceeding a predetermined limit, and an amplifier 24 is interposed between the filter 23 and divdider 25. The arrangement is intended to allow the use of a practical low-pass filter 22 i.e. one in which the cut-off is gradual. Taking an example, if the spacing between the frequencies in the spectrum is 100 McS, F the frequency from the continuously-tunable oscillator 11 and Fi the nearest lower frequency in the spectrum, then the lowest beat frequencies in the output of the modulator 13 will be f = (F-Fi) and f 1  = (Fi + 100 - F). One of these will lie below 50 McS and with a filter 22 having a sharp cutoff at 50 McS would pass through the filter 14 for operation of the counter 14. A practical filter (Fig. 2) giving sufficient attenuation in the cut-off region will, however start cutting off at 45 McS and give appreciable attenuation at 50 McS; the second filter 23 allows of checking the synthesized frequency within this cut-off region of 45-50 McS. The output of the modulator 23 includes riot only the primary beat frequencies f and f 1  but also a secondary term (f 1 #f) i.e. Œ2(F, + 50 F) which after passing through the divider 24 gives the frequency Œ(F, + 50 - F). Thus if F lies between (F i  + 45) and (F i  + 55) McS the resultant secondary heat will pass through the second filter 23 which has a cut-off of 10 McS and can be applied to the counter 14. The switch 30 selecting an output alternatively from filter 21 or filter 23 is operated in accordance with the value registered in register 40 by means of a logic circuit 50.

Title: A data entry machine
Filed: 1966-11-04
Abstract: 1,115,753. Selective printing. NATIONAL CASH REGISTER CO. 4 Nov., 1966 [4 Feb., 1966], No. 49556/66. Heading B6F. An accounting or like data entry machine has a line-spacing mechanism which is automatically controlled according to whether or not the entry is of the same kind, e.g. a savings or a loan transaction; the line-spacing mechanism is controlled by a device which is actuated after the first depression of say a loan transaction to disable the line-space mechanism but after the second depression ensures that line-spacing does occur to avoid the new transaction being printed over previous transaction. The machine described is similar to that described in Specification 1,008,058 and the line-spacing and ejecting feeds are made by rotation of feed-rollers 30, Fig. 2. The rollers are on a shaft 28 driven by a pinion 31, gears 32, 34 and ratchet wheels 36, 58. These are rotated by a line-spacing pawl 39 and an eject pawl 57 mounted on an arm 40 driven by a pinion 81 and teeth 42 of a reciprocating slide 43. This is operated by linkage 45, 46, pitman 48, a follower 86 and a cyclically rotated cam 78. The movement of the pitman 48 is also controlled by an arm 59 forming part of a yoke 60 with a second arm 61. The arms are normally urged clockwise about a shaft 62 until arm 59 engages a stud 65 on the pitman, which when moved to the left to effect a line-spacing movement can pivot to prevent a return movement, i.e. an eject movement and a preparatory movement for a further line space. The movement of the arm is controlled by a link 64 which is depressed by machine rotation of a shaft 71 through an arm 70 if another arm 72 is allowed to move because a feeler 76 finds a recess in a preset control plate 77. The control plate is positioned in accordance with the transaction desired. Associated with the arm 59 is a second arm (82), Fig. 3, (not shown), which may be positioned behind the square stud 65 which also prevents a return movement of the line-spacing pitman 48. The arm (82) is controlled in a similar manner as the arm 59 from a control plate. Both arms 59, (82) move downwardly in certain operations and block return (rightward, Fig. 2), movement of pitman 48 but this operation may be disabled by a pair of solenoids 93 which latches the link 85 to ensure that a line-spacing operation occurs and holds this position if the machine operator repeats the use of transaction key which demands a line-spacing to prevent over-printing.
