Title: Improvements in indicating apparatus
Inventor: GILHAM ARTHUR WILLIAM STEWART
IPC: G01R17/04
Filed: 1962-01-25
Abstract: 993,855. Cathode-ray tube display systems. SHORT BROS. & HARLAND Ltd. Jan. 16, 1963 [Jan. 25, 1962], No. 2898/62. Heading H4T. The value of each of a plurality of different variables is indicated on a cathode-ray tube by applying electric signals representative of such variables sequentially and cyclically to the beam deflecting means of the tube. The invention is described as applied to apparatus for indicating the operating conditions of each of a plurality of aircraft jet engines. Such operating conditions involve, for each engine, jet pipe temperature, r.p.m., oil pressure and compressor delivery pressure and for display of these, separate beams of a multi-beam tube are - utilized. Thus, as shown in Fig. 1, each engine is provided with transducers 20 . . . 23 producing electrical signals corresponding respectively to the above conditions such signals being fed simultaneously to respective conductors 28 . . . 31 via gates 24 . . . 27 controlled by a decoding unit 33 fed with binary code signals from generator 18. The latter generates a plurality of different code combinations sequentially and cyclically which, via conductor 10, feed the decoding units 33 of the other engines so that each of the conductors 28 . . . 31 receive a succession of samples of the condition sensed by the corresponding transducer 20 . . . 23 of the other engines. The signals on conductors 28 . . . 31 are then supplied to a modifying unit 32 comprising averaging units 34 and difference units 35 which, for each of the input signals produce output signals corresponding to the deviation of the input signals from the average value of such signals. These output signals are then supplied to a multiple (four) beam cathode cathode-ray tube 36 to produce a vertical deflection of a horizontal time base which results in a succession of lines of dots 37 . . . 40 (Fig. 2) the spacings of which from predetermined datum lines 41 . . . 44 represent the departure of the sensed conditions from the average value. Additionally the average values may be indicated on suitably calibrated meters 45 . . . 48. To carry out a spot check on individual engines the generator 18 may be stopped at the appropriate point in its cycle or it may be switched out of circuit and suitable static code signals applied to the cable 10. Instead of a horizontal display the indications may be provided in a circular array or in radial arrays.

Title: Process for extracting gelatinous polysaccharides
IPC: C08B37/00
Filed: 1959-01-27
Abstract: Gelatinous polysaccharides are obtained by irradicating precursor-containing material with ionizing penetrating radiation and extracting said polysaccharide from the irradiated precursor material.  Typical of the polysaccharides are acacia, karaya, tragacanth, agar-agar, locust kermel and locust bean gums, pectin and alginic acid.  The naturally occurring precursor materials include various plants and trees, and exudates therefrom, seaweeds, seeds, fruit and vegetables and their extracts.  These materials may be treated in any form but are preferably irradiated in substantially dry form.  The radiation employed includes beta rays, cathode rays, gamma rays, e.g. cobalt-60 and X-rays and may have an energy up to about 15 Mev., preferably 10-3 Mev. up to 4,0 Mev.  The irradiation may be effected by passing the material through the radiation beam at distances of the order of 1 inch to 18 inches for periods ranging from 5 secs. up to 8 hours. The preferred dosage range is 0,5 to 4,0 X 106 R.E.R. The precursor material is then extracted by known method to obtain the polysaccharide.  Examples of the irradiation of oranges and seaweed with cobalt 60 before extraction of pectin and alginic acid, respectively, are given.

White cement clinker is produced from green pellets of the raw material of particle size 2 to 15 mm. diameter on the moving grate of a band sintering apparatus 1 by passing the pellets successively through zones 8, 9, 12, 14, 15, 16 where the sinter bed is preheated and dried, sintered, " after treated " in a reducing atmosphere above 900‹C., cooled to below an oxidising temperature and finally cooled to atmospheric temperature, the heating and cooling being by gas. The sinter bed consists of a lower grate protecting layer 3 of inert material coarser in size then the raw material green pellets in layer 5, and a top layer 7 of preburned pellets. Under hood 8 drying is at 300‹C. to 400‹C., sintering under oxidising conditions at 1000‹C. to 1400‹C. under hood 9 and before sintering at 1400‹C. to 1460‹C. in a reducing gas under hood 12 a layer 19 of finished clinker up to 4 mm. size is placed on layer 7 by hopper 11. In the " after treatment " zone 14 reducing gases at 1050‹C. are drawn through the bed at a reduced speed and in the reducing cooling zone 15 reducing gases decreasing in temperature from 400‹C. to 200‹C, are drawn through the bed at an increased speed to reduce the temperature of the upper layer to below 500‹C. A further protective layer 20 of finished clinker is added to the bed from hopper 16 before the final cooling to 100‹C. by atmospheric air in zone 17. The coarse grate particles from layer 3 are sieved and recycled to hopper 2, the fines from layer 5 are returned to hoppers 11 and 16 and the layer 5 is separated from the finished white clinker 7 and returned to hopper 6 for refeeding. The exhaust gas from hood 9 is recycled to hood 8, gas from hood 12 to hood 15, and gases from 14 and 15 are mixed with the gas in hood 9.

Title: Improvements relating to pressure oil accumulators
IPC: F15B1/18
Filed: 1960-02-02
Abstract: 891,511. Hydraulic accumulators. SUGIMURA, K. Feb. 2, 1960, No. 3630/60. Class 69 (2). An hydraulic accumulator comprises an elastic oil cup 1 mounted on an oil supplydischarge valve 2, 4, Fig. 2, or above an oil supply-discharge hole 8, Fig. 4, to protect the gas reservoir 11 from damage on the valve or from being pushed through the hole, the oil in the cup eliminating frictional contact between the reservoir and cup. In an embodiment for use with high pressure oil, the accumulator is provided with the supply-discharge valve consisting of a poppet valve 2, Fig. 2, and check valve 4 connected by a dashpot 5 and spring 6. As oil is discharged from the accumulator, the reservoir 11, which is of oil-proof synthetic rubber, engages the cup and moves the valve downwardly first to close the check valve and then the poppet valve. The cup, which is of similar material to the reservoir, prevents the reservoir being caught between the valve 2 and its seating 3, and oil in the cup eliminates frictional contact between the cup and reservoir. In an alternative embodiment for low-pressure oil, the reservoir deforms the cup as oil is discharged through holes 8, Fig. 4, to close the latter and prevent extrusion of the reservoir through the holes.
