[Also in Division H3] Apparatus attached to a coin sorter counts the numbers of each denomination and aggregates the value of the coins. As shown 6d., 1/-, 2/- and 2/6 coins apply pulses respectively to terminals B1-B4 to set up a related store CS1-CS4. A distributer PD applies pulses to the stores sequentially and any store which has been set up sends out a pulse on lead CC to the particular denomination counter and one or more pulses on lead CE to a grand evaluation counter. Fig. 2 shows the half-crown store, the basic unit being sixpence. With the discharge in V2 on cathode K0 a coin pulses terminal B4 to shift the discharge to K1. At each cycle of the distributer PD a drive pulse at A4 shifts the discharge along in known manner. When the discharge reaches K4 a pulse appears at CC to advance the related coin counter. The next five steps produce pulses at CE each representative of sixpence to advance the value counter. When the discharge reaches K0, transistor VT1 conducts and gate V1 is closed. The circuit may be tested by potential on lead C which produces continuous cycling.

A thread guide roller, the effective diameter and thread-gripping action of which may be varied simultaneously, comprises annular discs 1, 2 integral with or mounted upon sleeves 3, 4 respectively, and having circular rows of intermeshing projections 13, 14 the thread-contacting faces or edges of which are concave and which thereby define a groove in which the thread runs in its path around the roller. While the sleeve 3 is fixed relative to the shaft 6 the sleeve 4 may be adjusted axially by means of a nut 7 to vary the effective diameter of the roll and at the same time to vary the angle of intersection of the juxtaposed concave surfaces. At increased effective diameter the amount of slip of the thread relative to the roller is increased and the angle of intersection reduced, both factors contributing to an increased threadgripping action. The reverse is true for a reduced effective adiameter. The projections 13,14 may be mounted between annular members or rings 9, 10 and 11,12 and fitted in annular recesses in the discs 1, 2. The cross-section of the projections in a plane perpendicular to the radius may be rectangular or trapezoidal. The roller finds particular application as a preliminary doffing roller of the type that runs at greater speed than the thread in a textile double-twist twisting machine.
