Abstract: 1,181,274. Control systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 June, 1967 [21 June, 1966], No. 27916/67. Heading G4H. In a control system in which the actual position of a member is represented by a frequency signal f i  (Fig. 3) and the desired position is represented by a number stored in a preset member SE M , a counter Z receives the frequency signal during predetermined scanning intervals at the end of which the count is counted either up or down until it reaches the required position to give either a time interval output signal (on leads A V1  or A R1 ) or a pulse series (on leads A V2  or A R2 ) which represents the deviation from the required position. In the embodiment described in which at the end of the scanning interval pulses of frequency f p/2  are applied via either gate G R2  or F V2  to be accumulated either negatively or positively in counter Z until the number stored in preset member SE M  is reached, after each scanning interval the number stored may be amended to reduce the length of the scanning intervals, for example if the required position is represented by a frequency of 876 cycles/sec. and the scanning intervals last only 1/100 sec. for certain intervals 8 is stored in the preset member this being amended to 9 in other time intervals (in the example described the second and third for example).

A machine for turning piston and like rings with a conical surface, comprises a tool and support having a feeler and guide for taper turning, in which the feeler is alternately clamped and released relative to the support and during a traverse so that the tool is alternately moved towards a batch of rings to cut the surface of a ring, and away again to start the next ring. The rings 2 are mounted in a batch with spacers 3, of smaller diameter than the smallest diameter of the ring, interposed between each ring, the whole being supported between centres 5, 6. A slide 8, shown carrying two tools 7, is spring-pressed away from the work and up to a limit-stop, with the tools clear of the maximum work-diameter. An adjustable bar 18 controls the taper feed through a feeler 15, which is spring-pressed away from the work and clamped during the taper-cutting by a fluid-operated member 24. Pressure for the latter is supplied from an electro-magneticallycontrolled valve 28, the circuitry for which includes the work and tool or tools. When the tool disengages the work at the end of a tapercut, the feeler is released and the tool-slide 8 automatically moves outwardly to relieve the tool and position it for the next taper-cut. The valve 28 automatically closes again, and the tool starts the taper-cut on a new ring. The process is continuous as the carriage 9 for the tool-slide 8 is moved along the work.
