Each key lever has 12 holes and 12 guide notches, and tabs are clipped into a unique combination of these. Each tab bears two connected metal-coated areas, so that when the key is depressed, the tab descends between two transducer strips, and the areas provide capacitative coupling between coplanar input and output regions on the strips. Each strip has, on one surface, the input region connected to an oscillator and the output region connected to a detector in the output channel to produce D.C., the two regions being separated by an earthed region which also extends to the other side of the output region. The other surface of the strip is a single earthed region, and contacts the similar surface of the next strip (so that the two are back-to-back). Roller or sliding pellet mechanical interlock is provided to prevent more than one key being depressed at a time.

Title: Improvements in apparatus and process for removing solvents from enamel coatings on metal
IPC: B05D7/20
Filed: 1962-12-18
Abstract: Solvent is removed from the enamel coating on a moving strip of metal by simultaneously applying radiant and convection heat, the convection heat being supplied by a stream of gas heated to a temperature above the blister temperature of the enamel and flowing parallel to the strip in the same direction of movement. The wire 1 passes through a coating bath 2 and enters the oven 4 through an aperture 3 adjacent to which, on each side of the passage for the wire, are heating panels 5.  Air heated by a burner 8 and impelled by a fan 6 is directed, by a passage 11 having its exit adjacent the aperture 3, along the passage for the wire. The speeds of the wire and the air stream are such as to ensure evaporation of the solvent from the enamel without causing blistering or premature curing, final baking being effected after the wire has passed the solvent removal zone.  Specification 955,125 is referred to.  <PICT:1013306/C1/1>

Title: Improvements in and relating to the automatic calibration of decoding apparatus
IPC: H03M1/00
Filed: 1962-12-19
Abstract: 1,024,260. Radio navigation. CUTLERHAMMER Inc. Dec. 19, 1962 [Jan. 16, 1962], No. 47987/62. Heading H4D. Relates to the calibration of an aircraft receiver in radio navigation systems as described in Specifications 940,509, 992,543 and 1,014,633 wherein at least one ground beacon employs a scanning beam pulse-coded as a function of the angle thereof. In such a receiver, the angle of elevation from such a beacon is decoded by means of a linear sawtooth sweep waveform generated in a unit 57, the waveform commencing to rise from a predetermined potential, e.g. earth potential, at the end of a gating pulse. the beginning of which coincides with a received pulse and causes the collapse of the sweep waveform. According to the present invention a plurality of series of test pulses having respectively different pulse intervals representing different beam angle pulse modulations are generated (86, 87), a corresponding plurality of calibration signals are provided (95), the test pulse series and corresponding calibration signals are applied to the receiver decoder (57, 58) during intervals between receptions of the scanning beam by the receiver to produce corresponding error signals, and means (101, 102) are provided to thereby control the amplitude but not the slope, and the slope, of the sweep gnerator output waveform. Detailed operation.-In Fig. 5a, the received beam pulses are shown at 68 and a series of test pulses at 85. Any-previously-stored angle signal in memory unit 60 is supplied via a control circuit 61 to the comparator 58 and an error signal output is produced which is integrated in unit 63 and thence supplied via units 64 and 65 to unit 60 so as to " up-date " the value of the stored signal; comparator 58 is described in detail in Specification 992,543 (Fig. 11 thereof). A detector 67 produces a trigger pulse 69, Fig. 5h, near the beginning of the scanning beam passage and may incorporate an integrator, a Schmidt trigger circuit and a differentiator; a multivibrator 71 derives from the trigger pulse a pulse 72, Fig. 5c, at least as long as the duration of a scanning beam passage. A generator 73 develops a gating pulse 76, Fig. 5e, of fixed duration immediately following the end of pulse 72; gating pulse 76 is applied to a control unit 65 so as to deliver the error signal 75, Fig. 5d, to unit 60. Pulse 76 gives rise to a pulse 79, Fig. 5f, to discharge error integrator 63, and to a pulse 84, Fig. 5g, from a generator 83; the latter pulse effects a calibration.
