Title: Process and apparatus for continuous casting of metal billets
IPC: B22D11/124
Filed: 1951-02-27
Abstract: 687,040. Continuous-casting machines; casting processes. JUNGHANS, S. Feb. 27, 1951 [June 2, 1949; Sept. 17, 1949], No. 4755/51. Class 83 (i). In the continuous casting of metal in a bottomless highly-cooled mould 2, the emerging metal with its periphery solid is cooled so slowly that pipes and segregations are not formed. This may bE effected by passing the emerging metal S' through an equalizing chamber 3 which may have guide rollers 8 and be subdivided, the different zones being at different temperatures or filled with different gases, e.g. air, steam, nitrogen. The fluid column S<SP>2</SP> must be so long that the fluid pressure reduces or eliminates the undesired formations. In the case of a steel bar 100 mm. in diameter a length of fluid column of 2400 mm. gave a pressure at the tip S' of 1.7 atmospheres. The bar leaves the mould at a surface temperature of 1350‹ C., the temperature of the gas in the chamber 3 is kept at 600‹ C. and the bar leaves the chamber with a surface temperature of 1150‹ C. To avoid internal cracking the rollers 5, 6 which control the rate of descent of the bar, should engage it at a point below the tip S<SP>4</SP>. Cooling sprays 10 may be used if required.

J., 151, Kirkstall Lane, Headingley, Leeds. Feb, 17, 1931, No. 4963. [Class 139.] Chimes ; striking mechanism.-In turret and other clocks the striking or chiming train is driven by a fast-running (e.g. electric) motor through an epicyclic, differential, or planetary train of gears, which train is positioned between the motor and the clock mechanism, and automatically disconnects the motor from the clock mechanism when the latter becomes locked and transfers the power to another element (e.g. to drum E to raise weight e<2> and switch off the motor). The fly or fan shaft A of the striking or chiming train has rigid with it a sun-wheel F which is driven through planets e by an internally toothed wheel D rigid with a member C which is free on shaft A and is driven bv wheel b and worm B from an electric motor. The planets e are mounted on a drum E which is free on shaft A and has passing round it the cord e<3> of a weight (or spring) e<2>. Nuts e<4>, e<5> actuate a switch member G for the motor. When shaft A and wheel F are released, weight e<2> sinks (C, b, and B being stationary) and almost immediately moves G to switch on the motor. Thereafter the weight e<2> holds drum E whilst the motor drives shaft A.

Title: Improvements in or relating to apparatus for measuring time intervals between emitted and reflected sound impulses
IPC: G01S1/72
Filed: 1927-02-22
Abstract: 290,754. White, A. E., (Sperry Gyroscope Co.). Feb. 22, 1927. Determining distances acoustically. - Apparatus for measuring the time interval between an emitted sound signal and the reception of the echo from a distant object comprises a signal transmitter and signal receiver operatively associated with mechanism for rotating a graduated disc through an angle proportional to the time interval thus giving a continuous indication of the distance of the reflecting object &c. A shaft 1 driven at constant speed by a motor 2 has mounted upon it a crank 3, cam 4, insulated rings 5, 6 and brushes 7 and 8 that in rotating make contact with segments 9, 10 carried by a dial wheel 12 having insulated portions 36 between the segments. The rings 5, 6 are electrically connected with brushes 7, 8 and also with a source of direct current. A second shaft 11 in alignment with the shaft 1 carries the dial wheel 12, insulated rings 13, 14, and a ratchet wheel 15. The rings 13, 14 are electrically connected to segments 9, 10 respectively, the circuit being continued through the coils h, of an electromagnet 18 when the contacts e, f are closed. A pawl 16 is pivotally mounted on a rod and is made to oscillate about the shaft 11 by the crank 3 and linkage 17. When the cam 4 closes the contacts 19, d, a signal is emitted. The echo is received on a microphone 21 causing a current to flow in a circuit, the current being amplified by thermionic devices to energize an electromagnet 27, making contacts e, f and the circuit of electromagnet h, g which causes the permanent magnet 33 to swing about its pivots 34 and move the pawl 16 into engagement with the ratchet wheel 15. With the reception of successive echo signals the wheel 16 and drum 12 are turned until the arm 7 is on the insulated gap 36 when a signal is received. The drum 12 then remains stationary. If the drum overshoots the arm 7, the arms 7 and 8 contact with opposite segments to those engaged before and the current in the magnet h, g is reversed the other end of the pawl being drawn down to drive the ratchet wheel in the opposite direction until the arms 7, 8 are on the gaps. Contact 28, j are provided to short circuit the coil 27 when signals are emitted. In a modification, a shunt-wound motor is used to rotate the shaft 11 instead of the pawl and linkage. In another modification electric condensers are used in conjunction with the electromagnetic mechanism for controlling the pawl 16.

Abstract: 1,191,821. Polyimide coating. MONSANTO CHEMICALS Ltd. 8 Jan., 1968 [3 Feb., 1967], No. 5362/67. Heading B2K. [Also in Divisions B5 and C3] A condensation polymer is made by reacting an amine containing two or more primary amino groups with a polycarboxylic anhydride obtained by heating an aromatic polysulphonyl halide with an aromatic carboxylic anhydride under such conditions that sulphur dioxide and a hydrogen halide are evolved and direct linkages are formed between nuclear carbon atoms of the original polysulphonyl halide and those of the original carboxylic anhydride; derivatives of the polycarboxylic anhydride, e.g. the corresponding acid or partial esters thereof, may also be used. Both the aromatic sulphonyl halide and the carboxylic anhydride may contain one or more nuclei, in the latter case the nuclei may be linked directly or through an intermediate atom or group, e.g. oxygen, sulphur, carbonyl or sulphonyl. The nuclei may be carbocyclic or heterocyclic, or consist of a heterocyclic ring fused to a carbocyclic ring, and may contain additional substituents. The condensation may be carried out in the absence or presence of an inert solvent, the first reaction product being a polyamic acid, which may be converted by heating or by chemical dehydrating agents to a polyimide. Preferably, the polyanhydride is first converted to a partial ester by reaction with a monohydric alcohol. The polyimide products may be used as surface coatings, or as binders for fillers, e.g. powdered silica alumina, titania, zirconia, silicon carbide or alumino silicates, or for fibres or filaments of asbestos, silica, carbon, aluminium silicate, boron nitride, silicon carbide or glass. Examples describe the production of a polyanhydride from m-benzenedisulphonyl chloride and phthalic anhydride and its reaction, or that of its partial esters with p-phenylene diamine, m-phenylene diamine, ethylene diamine or 4, 4'-diaminophenyl ether, and the use of the products for coating steel bars or for the production of laminates from aligned carbon fibres, woven silica fibre cloth, fibrous aluminosilicate felt and glass cloth.

Abstract: 1,213,853. Stabilizing ships. MUIRHEAD Ltd. 23 Jan., 1969 [2 Feb., 1968], No. 5374/68. Heading B7M. A ship's stabilizer has a tank system which when filled with liquid has a resonant frequency lying with the range of rolling frequencies likely to be experienced by the ship. The system comprises two tanks 4, 5 having an interconnecting liquid passage 6 between their lower end portions and having the liquid flow between them at the resonant frequency influenced predominantly by the rolling motion of the ship and also by a booster arrangement 14. This latter is controlled to assist the resonant liquid flow by imparting to the liquid a force which varies with rolling and which is controlled by a system 21 actuated by roll-sensing means 30 which respond to the rolling movement of the ship. The booster arrangement is designed to provide a limited power output insufficient to operate the stabilizer as an untuned active stabilizer. In the embodiment shown the force is applied by differential gas pressure applied to the upper portion of the tanks from gas in reservoirs 15 and 16 by way of a valve forming the control system 21.
