Title: Production of isoprene
IPC: C07C4/10
Filed: 1959-10-01
Abstract: Isoprene is obtained by cracking neohexene.  The reaction is effected at 650 DEG -900 DEG C. and 0,1-10 atmospheres for 0,01-1 second, preferably in the presence of silicon carbide. Unconverted neohexene is recycled.  Neohexene may be obtained by dehydrogenating neohexane over an acid-free catalyst, e.g. platinum on chromia on alumina, at 450 DEG -900 DEG C. and 0,1-10 atmospheres for 0,2-100 seconds. Alternatively neohexene is obtained by isomerizing dimethylbutenes, by the dehydration of methyl tert. butyl carbinol or the pyrolysis of the tertiary hexanol obtained from hydrolysing the reaction product from tert. butyl, butyl chloride and ethylene over aluminium chloride or ferric chloride.  Neohexane is obtained from C6 petroleum feeds preferably with isomerization of the residue, or by the isomerization of hydrogenated propylene dimer or by reacting isobutane and ethylene.

Title: Improvements in or relating to solids concentration measuring and regulating devices
IPC: G01N11/10
Filed: 1958-10-20
Abstract: 892,389. Mixing solids with liquids in flow. FISCHER & PORTER CO. Oct. 20, 1958 [Feb. 5, 1958], No. 33435/58. Class 86. [Also in Groups VIII, XIX and XXIX] A device 2 for measuring the solids concentration of a slurry &c. e.g. paper pulp comprises a casing 4 forming a passage for the slurry and having an inlet and a discharge opening, obstructions 30 in the path of the slurry to subject it to shear and means 64 to measure the stress in shear of the slurry, the spaced obstructions occupying less than 30% of any cross-sectional area of the flow path. The fibrous slurry passes from a stock chest 104, Fig. 3, through a pipe system 106 in which it is diluted by water from a line 108 and is delivered by a pump 102 to the device 2 from which it is discharged into line 110. As the slurry meets projecting rods 30, Fig. 1, it is sheared and the resultant force moves a drag body 19 upwardly. The body 19 comprises a sleeve 20, mounted on a stem 18, and rods 30 inserted in bores 32, 34, 36, 38, 40, adjacent bores having their axes 90 degrees apart. The stem 18 exerts a force on a lever 68, Fig. 2, pivotally mounted on a diaphragm 70, through a pressure balanced diaphragm 64 and link 76. The lever 68 transmits the force to a transducer 98 supplied with air by a line 116 which converts the force exerted by the lever 68 to a pneumatic or electrical output to give a signal to a recorder-controller 120 connected to an air supply line 122 and which has previously been adjusted to give the desired solids concentration at the output. Change in the signal transmitted to the recorder-controller 120 causes an opening or closing of a valve 128 which increases or decreases the flow of water in the line 108 and hence alters the solids concentration. A purge line 94 provides a flow of water to a chamber 82, Fig. 2, formed by a diaphragm 84, a hydraulic line 80 and a casing 54 to prevent plugging of the material in the slurry. Oil is contained in a body 66 between the diaphragms 64 and 84. In a modification, not shown, the projecting rods 30 are replaced by a number of obstruction members fixed to the casing, adjacent members being positioned 90 degrees apart from each other. A differential pressure transmitter measures the difference in pressure between the upstream and downstream sides of the obstructions.

Filed: 1927-12-15
Abstract: 313,891. M³ller, C. Dec. 15, 1927. Drawings to Specification. Wire; metal foil.-Alloy films or filaments of a thickness not exceeding 0.008 millimetres are made by diffusion of the components when applied to one another in thin layers, or by the application to a fine wire of one element' of a coating of one or more other elements, with or without the application of heat. The thin layers may be produced electrolytically, by deposition from metallic vapour or metallic compounds, or by cathode atomization, and they may be deposited on a thicker base which is subsequently wholly or in part removed. The base and associated thin layers may be rolled or drawn. Complex foils or filaments are made by removing a portion or portions of one or more layers prior to alloying, or the base may be coated along its length with layers of different elements. The foils or filaments are maintained in the desired shape during alloying by springs, weights, electrostatic forces, or gaseous pressure. To facilitate handling and shaping the wires may have a reinforcing coating which is subsequently removed. A coated filament may be alloyed by heating, for example, by suspending it within an electrically heated tungsten coil. Alloys of two or more of the following elements are described, namely, aluminium, antimony, bismuth, boron, cadmium, cerium, chromium, copper, gold, iridium, iron, magnesium, manganese, nickel, palladium, platinum, selenium, silicon, silver, tantalum, tellurium, tin, tungsten, and zinc. The alloyed filaments may be modified for certain purposes by forming a thin coating thereon of a carbide, iodide, nitride, or sulphide. Transformer cores are made by electrolytically depositing alternate layers of iron and nickel which are alloyed by heating. Proportions mentioned are 78 per cent nickel, 22 per cent iron, and 50 per cent nickel, 50 per cent iron. The foils and filaments are particularly useful as thermo-couples, and in thermometric and magnetic devices. A measuring instrument for weak radiations is described, in which a thermo-couple is mounted within concentric copper and silvered glass tubes, the leads from the couple, and the base of the tubes being immersed in liquid nitrogen.

Abstract: 1,059,710. Pulse radar. SPERRY RAND CORPORATION. Nov. 9, 1956 [Nov. 14, 1955], No. 34418/56. Addition to 895,161. Heading H4D. In a pulse radar system suitable for use as a moving target indicator the pulse is passed through a delay line before transmission and is broadened by the different delay times of the components of the pulse frequency spectrum. The frequency components are thereby displaced or swept, in time. The broad echo signals are applied, by a gating system, to the same delay line to effect compression of the pulse to its original shape. The sequence of application to the delay line of the frequency components of the transmitted pulse is opposite to that of the received pulse. The delay line may be a filter having a progressively varying time delay to different input frequencies, a wave guide, coaxial line or a helix-type travelling wave tube.
