A counter 50 comprises a head part 51 mounted on the rail 16 and a horizontal rod 62 having notches 63 for engagement with an actuating lever 81 mounted on an arm 78 of a bell-crank lever 73, the other arm 77 of which carries a roller 83 projecting into the interior of the rail 16 for actuation by the upper end of the carriage support member 24. The counting rod 62 carries three spaced recesses 96a-96c in any of which a stop block 97 is mountable, the block 97 being adapted to co-operate with a limit switch 101, Fig. 8. The rod 62 also has detent recess 66 to engage a spring ball detent 68. In operation, a workpiece 14 is supported in the carriage 23 which is then moved to the left. The block 97 is placed in the appropriate recess 96a-96c corresponding to three, two or one complete reciprocations of the carriage 23. A handle 72 on the rod 62 is manually rotated anticlockwise and the rod moved leftwardly until a start block 106 abuts a wall 54. The handle 72 is then rotated clockwise to cause the block 106 to operate a start switch 107 to cause the head 13 to move into operative grinding position. As the shaft 14 is ground, the rightward tilt of the belt 20 causes the shaft, and hence the carriage 23 to move to the left. Immediately after the commencement of this movement, the upper end of the member 24 engages the roller 83 to shift the rod 62 by one notch. The leftward movement continues until the actuator 47 engages the limit switch 44 whereby the tilt of the head 13 is reversed and rightward movement commences, during which the roller 83 is again engaged to shift the rod 62 by another notch. Reciprocation continues until the block 97 on the rod 62 engages the switch 101, thereby moving the head 13 away from the workpiece.

Abstract: 908,837. Aerials; radio navigation. STANDARD TELEPHONES & CABLES Ltd. July 10, 1959 [July 16, 1958], No. 23783/59. Class 40 (7). Radio beacon apparatus includes means to radiate a single rotating cardioid pattern of amplitude, the origin of the cardioid being made to move repeatedly around a closed circle of diameter at least two and a half wavelengths at the beacon transmitter frequency, and means to radiate a reference wave in synchronism with the rotation of the cardioid. Reduction of bearing errors arising from multi-path propagation is stated to ensue. In one arrangement a cardioid maximized in a direction tangential to the circular ring of radiating elements is produced by coupling one element directly to transmitter E and a neighbouring element thereto via a quarter-wave delay line L. The transmitter carries as a reference wave a frequency modulation synchronized with the rotation of the commutator switch; the frequency modulation is compared in phase with the rotation-induced amplitude modulation at the receiving point in known manner to determine the direction from the beacon. A further switch S is provided so that the two aerial elements coupled at any instant to the transmitter may be interchanged continuously at a repetition rate much higher than the commutation rate. To remove ambiguity at the receiving point switch S is stopped during every alternate rotation of the cardioid. Speech modulation may be provided for. In another arrangement a ring of earthed reflectors is included to produce a cardioid maximized in a direction away from the centre of the aerial array, Fig. 2 (not shown). It is preferred to space adjacent aerial elements in the ring by not more than a half-wavelength.
