Abstract: 1,231,255. Facsimile apparatus. MUIRHEAD Ltd. 8 July, 1969 [20 Sept., 1968], No. 44844/68. Heading H4F. In a facsimile transmitter adapted to scan only an intermediate area of a document 10 such as a telegram form, the document 10 is fed manually into an inlet slot 1 and between a pair of parallel rollers 4, 5 defining a drive nip to engage a stop which, in the embodiment, consists of radial tines 13, on an axially pivotable shaft 12, protruding through vertical slots 14 in a guide plate 3 into the path of the document 10. The tines 13 are retained in the upper position shown by the magnetic engagement of an armature 16 on the shaft 12 and a fixed magnet 17. Further manual insertion of the document merely results in buckling. However, when the drive roller 4 of the drive nip is activated the document 10 is pushed more firmly against the tines 13 and causes them to rotate downwards, the magnetic attraction between the magnet 17 and armature 16 being insufficient to resist this motion. The document 10 is thus guided past a horizontally reciprocating scan head (not shown) whose spacings above the upper position of the tines 13 and below the drive nip rollers 4, 5 correspond respectively to the spacings of the lower and upper limits of the intermediate area to be scanned on the document 10 from the lower and upper edges respectively of the document. Thus when the desired area has been scanned the upper edge comes free of the rollers 4, 5 and the tines 13 reach their lower positions where they no longer prevent the document 10 from falling out of the apparatus under its own weight. The tines 13 then return to their upper position under the influence of the magnetic attraction exerted between the magnet 17 and the armature 16.

Abstract: 1,265,129. Phase comparators. INTERNATIONAL BUSINESS MACHINES CORP. 13 Nov., 1970 [22 Dec., 1969], No. 54013/70. Heading H3A. An automatic phase control system for a data receiver including a phase comparator for comparing the data and clock signal is characterized in that the comparator comprises: a first detector 76 for detecting transitions of the clock signal of a predetermined polarity, e.g. positive; a second detector 78, 80 for detecting transitions of the data signal of both polarities; and means coupled to the detectors for producing pulses having a duration equal to the time intervals between the transitions of the clock and data signals. The outputs from the transition detectors are applied to bi-stables 82, 84, which are set by negative and positive data transitions respectively, when the clock signal is positive, and to bi-stables 86, 88 which are similarly set when the clock signal is negative. The bi-stables are intercoupled so that only one can be set at any one time. Arrival of a positive-going transition in the clock signal produces an output pulse from pulser 76 which causes a capacitor in integrator 102 to begin charging. If a transition occurs in the data signal whilst the clock signal is at its positive level, an output pulse from pulser 78 or 80, depending on the sense of the transition, will cause the capacitor to start to discharge, and will set bi-stable 82 or 84. At the end of the discharge period, the bi-stable is reset. The outputs E or F from the bi-stables are thus pulses with a duration proportional to the phase difference. If the clock signal reverts to its negative state before the arrival of a data transition, a "quench" signal will be produced to discharge the capacitor. Either bistable 86 or 88 will be set by the next transition in the data signal and will then be reset by the following positive clock transition. The outputs M or N thus have a pulse width determined by phase difference in the opposite sense. In order to minimize the effects of noise, the signals E, F, M, N are combined with data and inverted data signals in AND gates 90, 92, 94, 96 and the resulting signals combined in OR gates 98, 100 to provide a variable pulse width clock phase control signal J or P depending on which signal is leading.
