Abstract: 968,927. Driving belts. WILLAN & DICKINSON Ltd. Aug. 28, 1963 [May 29, 1962], No- 20546/62. Heading F2Q. [Also in Division B4] In a method of manufacturing tapered and bevelled links, A, B, Fig. 7, for a V- belt composed of a series of overlapping links, a strip 1, Fig. 3, of belting having its edges bevelled in the same direction (see Fig. 4) is cut transversely at 2 and longitudinally at 3 to form pairs of links A, B. The belting strip may be produced by drawing material, consisting of or embodying a woven fabric, over a slotted bed past a row of inclined slitting knives. In the machine shown in Fig. 8, rollers 10, 11 feed the strip intermittently over the bed 12 of a cutter block 13 carrying a transverse blade 14 and longitudinal blade 15, the block 13 being reciprocated along a path inclined to the plane of the drawing to produce the bevelled cut 3 simultaneously with the cut 2. The links A, B then engage a divider 4 (Fig. 3) and the link A runs down a roller track to an anvil 24. The link B enters a slot 19 in a plate or arm 18 which is oscillated through 180 degrees to invert the link B before it also is passed to the anvil 24. A reciprocable tool 26 then punches holes 5, 6, 7 (see Fig. 7) in the two links and trims their broad ends. The completed links may be ejected by a jet of air. It is stated that the guillotine cutters 14, 15 may be replaced by a rotary cutter, and that the hole-punching and endtrimming operations may be performed in a separate machine.

The output of a chromatograph detector is applied to a voltage-to-frequency converter feeding a counter. A slope detector is also supplied with the input signal and controls the counter to integrate over each peak of the input signal. A further counter is supplied with clock pulses and is read out when the maximum value of a signal peak occurs, to provide a time indication. The binary-coded decimal outputs of both counters are registered in a thyratron store which is subsequently read out through stepping switches, serially by decimal digits to a punched or magnetic tape recorder. A relay decoder may be connected to the outputs of the stepping switches in order to control a printer. A record is thus made of the integral of each signal peak and the time at which the maximum value occurred. A summation of all the integrals may also be made.
