Title: System for feedback control of mould level in a continuous casting process utilizing a pour box
IPC: B22D11/20
Filed: 1970-05-08
Abstract: 1309296 Liquid level control systems USS ENGINEERS & CONSULTANTS Inc 8 May 1970 [8 May 1969] 22453/70 Heading G1N [Also in Divisions B3 and G3] In apparatus for controlling the supply of molten metal to a continuous casting mould, the level of the liquid in the mould 18, Fig.1, is sensed by a detector 24 to control the speed of a motor 22 driving the pinch rolls 20 withdrawing the solidified metal from the mould, and the motor speed, measured by a tacho-generator 30, determines the upper and lower limits in an automatic liquid level control system for the molten metal in an intermediate power box 12. The circuitry, Fig.2, includes a number of potentiometers pre-set to give the desired characteristics. The pinch roll speed signal on lead 32 is compared with the desired signal on potentiometer 100, the difference being integrated in amplifiers 102, 112 to produce a correction signal on lead 42. This is algebraically added to a signal representing desired average level in power box 12, pre-set on potentiometer 56, and compared with maximum and minimum allowable levels on potentiometers 50, 62 in comparators 54, 66, whereby relays 70, 72 are selectively energized so that the signal on a lead 74 represents an amended average level. To this is added (a) an additional height signal from pre-set potentiometer 76 and the sum compared at 84 with the actual level signal on lead 36 to stop liquid flowing into the power box when they are equal, and (b) a fall in height signal from pre-set potentiometer 80 and the sum compared at 86 with the actual level signal to start refilling the power box when they are equal, and to reset a timer 46 controlling integrating amplifiers 102, 112 at the end of each cycle.

Title: Improvements in or relating to pulse-radar equipment
IPC: G01S1/02
Filed: 1953-08-19
Abstract: 728,112. Pulse radar. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 19, 1953 (Aug. 22, 1952], No. 22874/53. Class 40 (7). Relates to a pulse radar with a normal range display, e.g. a P.P.F. 19, Fig. 2a, having an adjustable range marker 20 and a further similar type display, 22, Fig. 2b, displaying in expanded form a range internal 23<SP>1</SP>-23, Fig, 2a, centred about the range mark 20; as shown in Fig. 2b the expanded display has an open centre, the inner boundary 24, marker 25 and outer boundary corresponding to the ranges 23<SP>1</SP>, 20 and 23 respectively in Fig. 2a. According to the present invention the adjustable range marker is produced by applying an exponential waveform a, Fig. 3, synchronous with the pulse transmission together with an adjustable D.C. range voltage E to a comparator to generate a marker pulse when the input voltages are equal in amplitude and the displayed range interval is initiated by a trigger pulse generated by applying a second exponential waveform b together with the D.C. range voltage to a second comparator, the two waveforms a and b having the same time constant but different initial amplitudes so that the time interval between the 'marker and trigger pulses remains constant when the range voltage is varied, e.g. from El to E2. As shown in Fig. 1 the marker pulse is generated in circuit 17 by applying a sync. pulse from the timing circuit 12 to an electronic switch 34 shunted across a capacitor 29 which is in series with a charging resistor 30, the resultant waveform a at the junction of R30 and C29 being applied to the first comparator 31 together with the range voltage from potentiometer 3b, the output marker pulse from the comparator being applied to intensity modulate the main and expanded displays 19 and 22 to produce markers 20 and 25 respectively. The trigger pulse is generated by a corresponding cct 26 (29<SP>1</SP>, 30<SP>1</SP>, 31<SP>1</SP>, 34<SP>1</SP>) but the waveform b appears at a tapping 32<SP>1</SP> on R30<SP>1</SP> and the output pulse from comparator 31<SP>1</SP> triggers the highspeed time base generator 28 for the expanded display 22. Alternatively the switch 34<SP>1</SP> may be connected to the tapping 32<SP>1</SP> as shown by the dotted connection 35<SP>1</SP> or each sawtooth generator may comprise a parallel R.C. network connected in series with an electronic switch.

Abstract: 1,160,508. Metal pipe bundles sheathed in plastics. KABEL UND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 15 May, 1968 [16 May. 1967], No. 23066/68. Heading F2P. A method of manufacturing a pipe bundle cable consisting of copper pipes stranded together and surrounded by a plastics sheath, and which is intended to be used for the pneumatic transmission of measurements, control pulses, &c., wherein the copper pipes are stranded together and annealed in the form of a stranded bundle, and the plastics sheath is applied either during, or after, the annealing operation. The plastics sheath, e.g. polyvinyl chloride, can be extruded over the copper pipes as they pass, while still warm, out of an annealing device. Alternatively, the annealing and application of the plastics sheath may be a combined operation. Before the plastics sheath is applied the spaces between the stranded pipes may be filled by additional plastics material. The annealing may be carried out by direct current resistance annealing, by induction annealing, or by an annealing furnace, the annealing being carried out in a protective atmosphere, e.g. of water vapour. As shown, one storage reel 3 is located outside, and six are located inside a stranding basket 2 which is rotated to deliver as stranded bundle of seven copper tubes 4 successively to an electric annealing plant 5 and a plastics extrusion press 6 in which a sheath of thermoplastics material, e.g. P.V.C., is applied. The pipe bundle is then cooled, e.g. in a water bath, not shown, and wound up on a drum 7.

Title: Process for obtaining cellulose from vegetable raw materials
IPC: D21C3/16
Filed: 1937-08-24
Abstract: <PICT:0490102/IV/1> To obtain cellulose from vegetable raw material such as wood or straw, the material chopped and cleaned in the usual way is treated with 30-53 per cent preferably 38-45 per cent nitric acid at 10-25 DEG  C., preferably 10-20 DEG  C., rinsed with water, boiled for 2-3 hours in caustic soda or sodium carbonate of about 2 per cent strength, washed and dried.  The acid treatment is preferably effected in open concrete vessels covered with plates of acid-resistant stoneware or steel, and the washing out of the acid is performed in stages, a series of vessels moving in counter current to batches of washing water.  In this way the nitric acid is readily recovered for re-use.  Part of the nitric acid used may be replaced, e.g. up to 25 per cent by sulphuric acid of 55 DEG  B<\>ae. Container 1, the first of a battery of ten, is filled with 42 per cent nitric acid.  Basket 11 of wire mesh or perforated plate mounted on rod 12 carried by a displaceable bar 13 and containing chopped and cleaned straw is immersed in container.  After about 15 minutes the basket of material is transferred to container 2, and a fresh basket of material is introduced into container 1 and so on.  Adjacent containers 2-9 are connected by pipes 14, and as a basket of material is immersed in a container, liquid is displaced and flows into the preceding container.  Fresh water equal to the amount of liquid removed with a basket of completely rinsed material, is added to container 10 from a reservoir 15.  Concentrated nitric acid is introduced by p  pipe 16 into pipe 14a connecting container 2 with container 1 to bring the rinsing liquid in container 2 to the concentration derived for the acid treatment in container 1.  Any excess of liquid in container 1 is removed by pipe 17.  In a modification the containers with the raw material contained between two sieve plates, are moved on rails over stationary liquid containers, and the material containers are stopped over each successive liquid container for a period during which the liquid is circulated by pump through the material.  The liquid containers are connected as shown in the Figure, and after each circulation, the material containers are fed forwards while an amount of water, equal to the volume of liquid removed by a batch of completely rinsed material, is introduced into the last liquid container displacing a corresponding amount of liquid from each container to the immediately preceding one.
