Abstract: 1,258,802. Automatic temperature control systems. WESTINGHOUSE ELECTRIC CORP. Feb.3, 1969 [Feb. 14, 1968], No. 5644/69. Heading G3R. A control system for a multizone reheat furnace for metal slabs comprises a means for providing a signal representing the speed of slab movement and for controlling the speed, means for detecting the temperature and controlling the heat input in each zone, also a control means responsive to speed and temperature signals to effect a predetermined slab heat energy content by controlling both the speed of the furnace and the heat input. The arrangement is controlled by a computer 10 into which information is fed regarding slab thickness etc. and time required, which time is dependent on the anticipated period for rolling mills following the furnace to clear previously heated slabs. This time may be adjusted manually during passage of any slab to allow for predicted and unpredicted delays. Speed and temperature set points are then set by the computer which set points are then updated periodically so that the slab emerges at the predicted time and temperature. The characteristics of a slab are determined from curves derived empirically and experimentally and which are stored in the computer. The furnace has three zones, pre-heat, heat and soak, heat to each slab being added incrementally so that the final temperature is not reached until the slab reaches the exit of the heat zone. The soak zone is provided merely to redistribute the heat evenly throughout the slab. Signals may be of analogue form converted in digital converters for use in the computer, and digital output signals from the computer may be reconverted. At each slab discharge, computer 10 adjusts the speed and temperature set points for the slab following. During passage of any slab the computer may adjust the speed and/or heat input to ensure attainment of a desired temperature at the furnace exit point, and further movement may be prevented until the desired heat content has been absorbed. In such conditions a suitable warning is given. A similar condition would also apply if a slab had not remained in the soak zone for a sufficient time. In the Specification it is envisaged that approximately 80% of the heat will be added in the heat zone. A logical flow diagram for the computer is given in Fig. 3 (not shown) included in this circuit is an arrangement 190 to determine whether the mill following the furnace is operating at full capacity.

Abstract: 1296071 Control of photographic enlargers D PONTING 3 Feb 1970 [3 Feb 1969] 5707/69 Heading G2A An enlarger light is switched on for a period which is controlled automatically in accordance with the overall degree of illumination of the paper being exposed, a photo-sensitive device monitoring the illumination and controlling the current flow in a capacitor circuit from which a steadily varying potential is tapped to operate switching means for the enlarger, the photosensitive device being held on an adjustable mount adapted to be fixed on an enlarger baseboard and to receive light by reflection from a paper being exposed. Switch arrangement S 6  selects a capacitance value from capacitors X 1 -X 3 , this value being charged at a rate determined by the photo-cell by current through double triode V until the voltage across a relay C reaches a value sufficient to trigger the relay C, thus opening contacts C 1  to release relay B and end the exposure. A safe light may be switched inversely to the enlarger light, or may be switched off by operation of a switch S 3 . Closing of switch S 2  energizes relay A to open contacts A 3  in the photo-cell circuit so as to halt the timing circuit during an exposure, the timing resuming upon opening of switch S 2 . VR 2  may be adjusted to allow for the speed of the enlarging paper. VR 1  is adjusted so that a meter M gives a full scale reading upon tripping of relay C to provide visual indication of the progress of the timing sequence. Solid state devices may replace the valve.

Abstract: 1296962 Automatic control of linear dimensions LONZA Ltd 12 Jan 1970 [24 Jan 1969] 1479/70 Heading G3R The position of a dark zone influences a series of spaced photo-cells associated with trigger circuits producing constant currents, when associated with photo-cells on one side of the dark zone, which are combined and utilized to correct the position of the dark zone. In Fig.1, the diameter of thermoplastic tubing 6 is controlled by air supplied through a conduit 2 from a fan 1 while plasticizer and lubricant vapours are extracted through a conduit 8 by a fan 7. Tubing 6 is located in the path of light from a source 15, intermittently interrupted by a rotating disc 17, which falls on a series of photo-diodes 12a-12p associated with AC amplifiers 19a-19p and transistor trigger circuits 20a-20p. Only rays nearly tangential to the tube surface are weakened and this causes the trigger circuit corresponding to this position to produce a current and, by virtue of feedback circuits 23b-23p, all trigger circuits of lower denomination produce a current also. The sum of these currents, which thus corresponds to the diameter of the tubing, is compared with an adjustable current, corres-  ponding to the desired diameter, at 35 so that any error is effective, through a PI controller 37, to control a fluid-pressure operated valve 3 and thereby correct the diameter by variation of the air supply. If the diameter reaches an upper or lower limit corresponding to photo-diode 12n or 12c, operation of the associated trigger circuit opens a valve 4 or 10 to vent conduit 2 or 8 to atmosphere. A potentiometer 40 may be adjusted, with the aid of a voltmeter 42, to a voltage equal to that from controller 37 so that a switch 38 may be operated to change over to manual control without shock. Test voltmeters 22, 36 are also provided. Multi-point control, programme control, and control of air extraction instead of air supply are referred to.

The apertures and projections are so disposed in or on the respective members that in any position of relative rotation of the first and second members not more than one of the projections is aligned with an aperture and can be engaged therein. The indexing device which may be employed in a drawing apparatus to control an adjustable set square may be provided with a manually adjustable knob 50 which is secured to a spindle 24 forming part of the second member 21.

Then by rotating the knob 50, the member 21 is rotated relative to the member 31 until the knob is released when the bias of the spring 40 will cause one of the projections 28 to engage one of the apertures 34. The member 31 may be provided with a scale 52 and support one portion 54 of an adjustable set square while the knob 50 may have a mark for reading against a scale 52 and may be arranged to rotate, in conjunction with the member 21, a base member 37 to which another portion 53 of the adjustable set square is secured.
