Title: Controlling cast iron refining
IPC: C21C5/30
Filed: 1969-07-03
Abstract: The rate at which the carbon in the cast-iron is oxidised, the rate at which the slag is oxidised, and the coefficient K = CO / CO + CO2 , where CO and CO2 are the relative proportions of these gases in the exit gases are determined. Determination of K allows control of the oxidiation rate of the carbon in the cast-iron, by varying the supply rate of oxygen, and hence allows control of the refining process.

Title: Controlling numerical device using analogue valve - by time modulating device output and valve for comparison to give control signal
IPC: G01R17/02
Filed: 1974-10-14
Abstract: A numerical device is controlled by an analogue control value, following which the value appears at the output of the numerical device to represent of the position of the device. This controlled value is compared with the analogue value so as to obtain a control signal indicating the amplitude and the sense of variation necessary to counteract any difference. The method consists of converting the output value of the numerical device into a first time modulated signal, and of converting the analogue input value into a second time modulated signal so as to form the control signal for the numerical device.
Patent FR-2249041-A1 (FR)
Title: Detecting the edge of a hot glass ribbon - on a float glass tank using a movable radiation pyrometer
IPC: G01D5/39
Filed: 1974-10-18
Abstract: In a float glass tank, the location of the edge of the glass ribbons is detected by means of a probe of a radiation pyrometer which recieves radiation from the glass, the probe being located on the end of the shaft movable back-and-forth through the wall of the furnace, above the hod of the melt so that the variation of the radiation density can be measured. At any given temp. of the bath and the glass the change of temp. recorded as the shaft moves in and out can be related to the distance of the glass from the edge of the tank. This in turn, when measured on both sides of the tank, determines whether the glass is the correct thickness and is moving forward uniformly through the tank. Method is more accurate than direct observation visually or by closed circuit TV camera.

Title: Safety device for hang gliders - has lines raising trailing edge of wing lobes
IPC: B64C31/028
Filed: 1974-12-18
Abstract: The safety device prevents the lobes of a hang-glider wing from collapsing when, on occasion, a negative angle of incidence is adopted. This is achieved by keeping the trailing edges of the lobes in the raised position, preventing the wing from losing its normal operating profile-i.e. with the convex surfaces of the lobes on their upper surfaces. Two lines (2) are attached to the lobes, passing through the top of the upper mast (3) and down to the pilot who has at his disposal a securing device by means of which they may be kept taut, or released.
