Abstract

1327066 Knitting machines EDOUARD DUBIED ET CIE SA 25 Nov 1970 [28 Jan 1970] 55999/70 Heading D1C A knitting machine with electro magnetic needle selectors operable in accordance with the variable phase output pulses produced by a pulse phase shifting circuit 3 from a pulse generator dependent on the machine speed, the phase shift being a function of the frequency of the latter has a logic system which directs low frequencies direct (line 6) to a change over and shaping logical system 5 and the higher frequencies via a delay circuit 7, first integrator 9 and Schmitt trigger to the system 5, the change over being controlled by a tachometer circuit comprising a second Schmitt trigger and controlled by a second integrator 14. Pulses from system 5 control the orders to the electromagnets from a source 20. e.g. a programme reader, data processing unit or the like.
