The drum is provided with a stationary segment 8 over which runs a belt 11 which is driven in the direction of the arrow but at a slower speed than the drum so that the groups are rotated anti-clockwise and the trailing edge 38 of the connector strip wrapped around the group. The leading edge of the strip, 37a, is tensioned by contact with suction orifices 42, 43 and 44 in a suction block 34. Beyond the block 34 rolling of the groups is completed between the belt 11 and further belts 21 which travel at a speed in excess of that of the conveyer drum.

Abstract: 1,003,053. Selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 23, 1962, No. 44413/62. Heading G4H. [Also in Division G1] In an accelerometer, a mass 1, Fig. 1, is supported by springs 2 which allow movement in the x direction. The distance moved by mass 1, which is a measure of the acceleration to which the mass is subjected, is measured by means of a Michelson-type interferometer and a number of photo-cells 20 which sense movements of the interference fringes. Fig. 5 illustrates a circuit for obtaining a count representing the magnitude and sign of the acceleration using two photo-cells, though more may be used if desired. The signals S 1 , #S 1 , represent the current intensity of radiation falling on the first photo-cell 42, and the signals F 1 , #F 1  represent the intensity at some time earlier, bi-stable circuit 48 being set through AND gates 44, 47. Similar signals S2, #S 2  and F 2 , #F 2  are obtained for the second photocell 49. Logic circuits 55-64 produce a pulse for each displacement of the interference pattern by one fringe width, these pulses being applied to one or other input of a counter 65 according to the sign of the acceleration and the consequent direction of movement of the fringes. A computer 67 may be arranged to give an indication of velocity or position.

A control arrangement to maintain a predetermined illumination intensity at the drum 20 of a xerographic reproduction machine generally similar to that described in Specification 1, 089, 536 comprises an aperture mechanism 22 whose elongated opening 101 is varied in accordance with variations in the light sensed by a photo-cell 170 forming part of a balanced bridge including another photocell 180 acting as the reference, Fig.7 (not shown). The photo-cell 170 is positioned to receive light from a strip 190 on the platen 25, this strip being coloured (e.g. white) to produce a reference reflectance. Variations in the bridge output are applied to a differential amplifier 215 and pushpull-connected amplifiers 220, 225 to drive an electric motor in one direction or the other, this motor controlling movable aperture members 112, 114 through gears, Figs.3 to 6 (not shown).

The driving motor is braked by a resistor 250 and is controlled by limit switches 150; 151 which prevent the aperture from being opened or closed beyond desired points. The lens 33 is corrected for oblique spherical aberration in the tangential plane only, since the opening 101 has its longitudinal axis transverse to the direction of scan so that tangential light rays pass parallel to the opening while sagittal rays pass normal to it. Rapid response of the control system when the machine is started is provided by a lamp 172 which is energized when the machine is off to illuminate the photo-cell 170.
