Patent GB-2063826-A (GB)
Title: Controlling winding or unwinding of web rolls
IPC: B65H23/00
Filed: 1979-11-19
Abstract: In a method of controlling the winding of web material onto or off a roll the number of turns on the roller is determined and, when the number reaches a predetermined value, the speed of rotation of the roll is altered. The number of turns on the roller is determined by an optical system which measures the radial thickness of the web on the roller and which consists of a light source, a lens system and a calibrated linear array of photodiodes. The optical system involves setting up at a stage in the web winding or unwinding operation of a sharp profile image of the web roll periphery and focusing it on the calibrated array of photodiodes. The array is then continually monitored to determine which photodiodes are receiving light. The speed of rotation of the roll is altered when predetermined photodiodes either start or stop receiving light or infra-red radiation. <IMAGE>
Patent GB-2068596-A (GB)
Title: Parameter controller
IPC: G05B11/42
Filed: 1980-01-24
Abstract: A controller for controlling the value of a parameter, e.g. room temperature, produces a control signal related to the ratio between the error in the actual value of the parameter (as compared with a desired value) and the change in the value of the parameter over a preceding time period. As shown a sensor 5 senses the value of the parameter at any point in time whilst the desired value is set by means of a potentiometer slider 1. The outputs are converted to digital values and held in respective latches 8,4. The actual value is compared in a comparator 10 with the desired value to produce a difference or error signal and is compared in a subtractor 12 with a previous actual value (from a latch 9) to produce a signal indicative of the change in the value of the parameter during a predetermined time period. The ratio of the difference (error) and change signals is then derived by a divider 11 and utilised to control the value of the parameter. The controller is particularly applicable to the control of temperature, the sensor 5 then being a thermistor and the output signal being used to control a triac and thus an electrical heater or the pumping of water through a radiator. <IMAGE>
