Title: A device for Regulating the Exhaust of Flue Gases from Arc Melting Furnaces
IPC: F27D21/00
Filed: 1967-05-31
Abstract: 1,152,886. Removing exhaust fumes in arc furnaces. SVENSKA FL KTFABRIKEN A.B. 31 May, 1967 [29 July, 1966], No. 25176/67. Heading F4X. [Also in Division G3] A device for adjusting the amount of flue gas exhausted from an electric arc melting furnace, wherein said furnace includes an arch 3 provided with lead-in openings 2 for electrodes 4 and an exhaust dust 6 extending to a gas cleaner 12 and a fan 17, comprises a smoke detecting device 5 (e.g. a photo-electric cell) located above the furnace arch which at a set value of the concentration of leakage flue gas at this point operates means to control the rate of flue gas withdrawal through the duct 6, the object being to minimize flue gas leakage through the electrode openings 2 and to maintain a flue gas layer below the furnace arch to protect the arch from radiation. Exhaust gas flow control by detector 5 may as shown be by regulation of a damper 9 in a fresh air intake 8. In other embodiments, the fresh air enters the exhaust duct 6 through a gap at the jointing sleeve 7, or control may be effected by changing the cross-section of the throat 14 of the Venturi tubes 13 of the gas cleaner, or by controlling the speed of the exhaust fan.

Title: Organic diphosphine nickel complexes
Inventor: CHATT JOSEPH
IPC: C07F15/04
Filed: 1958-08-07
Abstract: The invention comprises complex compounds of organic diphosphines as defined below and zerovalent nickel in which a nickel atom is attached to two tertiary phosphorus atoms and to two carbonyl groups or to four tertiary phosphorus atoms.  The organic diphosphines are defined as aliphatic diphosphines having the general formula C2H4(PR2)2 and aromatic diphosphines having the general formula o-C6H4(PR12)2 wherein R is an alkyl or aryl radical and R1 is an alkyl radical.  The complex compounds in which a nickel atom is attached to tertiary phosphorus atoms and to carbonyl groups may be obtained by reacting an aliphatic diphosphine or an o-phenylene bis-(dialkyl phosphine) with nickel carbonyl in an inert atmosphere and complexes having nickel atoms attached to four tertiary phosphorus atoms are obtained by heating in an inert atmosphere an o-phenylene bis-(dialkyl phosphine) with finely divided nickel or with one of the aromatic complex compounds in which a nickel atom is attached to tertiary phosphorus atoms and to carbonyl groups. It is preferred to use nitrogen as the inert atmosphere and methanol may be used as solvent for the nickel carbonyl.  Examples are given for the production of (1) o-phenylene bis-(diethyl phosphine) dicarbonyl nickel by treating nickel carbonyl in methanol with o-phenylene bis-(diethyl phosphine) in a nitrogen atmosphere at 15 DEG C.; (2) di-o-phenylene bis (diethyl phosphine) nickel by heating a mixture of o-phenylene bis (diethyl phosphine) and the product of (1) for 2 hours at 150 DEG C. in a nitrogen atmosphere; (3) 1 : 2-bis (diethyl phosphino-) ethane dicarbonyl nickel by heating nickel carbonyl with 1 : 2-bis (diethyl phosphino) ethane in methanol solution under an atmosphere of nitrogen; (4) di o-phenylene bis (diethyl phosphine) nickel by reacting o-phenylene bis-(diethyl phosphine) with Raney nickel at 160 DEG C. for 8 hours in a nitrogen atmosphere, (5) 1 : 2-bis (diphenyl phosphino) ethane dicarbonyl nickel by reacting nickel carbonyl with 1 : 2-bis (diphenyl phosphino) ethane in benzene. The products are useful as catalysts in carbonylation reactions and in the polymerisation of acetylenes and olefines to yield cyclic hydrocarbons and examples are given for the production of triphenylbenzene compounds by polymerising phenyl acetylene in the presence of methanol using the products of Examples (1) and (5) respectively as catalyst.  Specifications 859,391 and 859,741 are referred to.

Title: Improvements in and relating to cathode ray tube systems
IPC: H04N9/24
Filed: 1957-08-13
Abstract: 869,538. Cathode ray tube circuits. PHILCO CORPORATION. Aug. 13, 1957 [Aug. 13, 1956], No. 25536/57. Class 40(7) [Also in Group XL(a)] In a cathode ray tube having a display screen, a plurality of secondary emissive indexing elements struck by the scanning beam and a secondary electron collector, the indexing elements and collector are so arranged that the transit times of electrons emitted at different times in the course of a scan follow a simple geometric curve. An indexing signal is generated from the target or secondary emission collector which can be applied via a feedback circuit to correct the phase of the video inputs or to correct the scanning speed, colour errors resulting from non uniform spacing in time of the indexing pulses due to transit time variations of the secondary electrons from different areas of the target to the secondary emission collector are corrected by so shaping and positioning the secondary emission collector and applying such potentials to the screen and secondary emission collector that transit time variation follows a simple geometrical law, e.g. a parabola, and a compensatory variation is produced in the scan waveform so that the phasing of the indexing pulses is rendered uniform in time. The experimental results show that the transit time is generally shorter from the edge areas of the screen than from the centre so that the line scan sawtooth waveform must have a greater slope at the centre than at the ends during the scanning of each line (the indexing and phosphorstrips being vertical) and a further similar variation in line scan waveform must take place during the frame scan so that the line scan speed is slower for short and longer for fast transit times. This is achieved by a resistance 48 and a capacity 49 to modify the horizontal scan of each line and a resistance 50 and capacity 51 feeding damper tube 54 via condenser 53 to modify the horizontal scan during frame scan. Suitable values are R 48  = 20 ohms C49 = 0À3 microforad, R 50  = 20 ohms C 51  = 120 microforads. Suitable potentials for the screen and secondary emission collector are 27 and 30 KV. respectively. The secondary electron collector 34, Fig. 4 is a wall coating on the flared envelope portion and preferably extends into the neck as shown. The conductive screen layer 35 may extend over the end face only of the tube as shown or over the flange 36 and a small part of the bulb, Fig. 1 (not shown). Button terminals 39, 40 enable D.C. potentials to be applied to coatings 34, 35, the coating 35 having a projecting portion 35 where it contacts terminal 40 and the coating 34 a corresponding recessed portion. An insulating coating may or may not be provided between the two coatings 34, 35. The face plate 33 is a separate thickened member sealed to the thin walled bulb 32. The scanning means 29 is preferably magnetic. Specification 753,442 is referred to.

Title: Improvements in hydraulic weighing scale pressure receivers
IPC: G01G5/04
Filed: 1950-10-20
Abstract: 730,174. Weighing-apparatus. AVERY, Ltd., W. & T. (Williams, L. S.). Oct. 20, 1950, No. 25565/50. Class 143. The invention relates to a hydraulic weighing scale of the kind having a load supporting platform 2 bearing on a plurality of hydraulic capsules 1 which each communicate pressure fluid to an associated bellows 5 adapted to convert the hydraulic pressure into force which is applied through a strut 9, a gathering lever 12 and a rod 16 to a steelyard 18; and consists in compensating for non-linear extension of the bellows 5 by inserting between the strut 9 and the lever 12 a plurality of pre-stressed spring plates 25 which have an initial curvature that increases with increases in load and so shortens the effective length of the strut 9 at an increasing rate as the load increases. In Fig. II four pairs of springs 25 extend between a pair of square blocks 26, 27 which are adjustable vertically by a nut 39 on a pre-stressing column 34, the block 27 having a groove in its base which co-operates with a knife edge 11 and lever 12. The force exerted by the spring bellows which tends to restore the lever 12 to a neutral position is also compensated by inserting a pair of spring plates 48 between a fixed bracket 50 and a lever extension 52 located vertically above the fulcrum 11a, the arrangement being such that a substantially constant force is applied to the lever by springs 48 at a moment arm which increases with movement of the lever, thus the' lever has a moment applied thereto which tends to accelerate its movements. Specification 640,911 is referred to.
