[Also in Division C5] 2-Methylbutane-2 is irradiated with light in the presence of a free oxygen-containing gas and a photosensitizing catalyst to produce two isomeric unsaturated hydroperoxides having the formulµ and the hydroperoxides are reacted with a C 3 -C 20  monoolefin in the presence of a molybdenum-containing catalyst to reduce the hydroperoxides to the corresponding unsaturated alcohols and convert the monoolefin to the corresponding epoxyalkane. Visible light may be used for the irradiation in the presence of a meso-tetraarylporphyrin catalyst. The second step may be effected with propylene, butylene, hexene-2 or octene-1 in the liquid phase at 75-100 C. in the presence of molybdenum hexacarbonyl or molybdenum oxyacetylacetonate.

Title: Improved method and apparatus for electric resistance welding of metals
IPC: B23K11/04
Filed: 1933-03-04
Abstract: 395,647. Electric welding. SCIAKY, D., 13, Rue Charles Fourier, Paris. March 4, 1933, No. 6644. [Class 83 (iv).] In order to restore the resiliency lost by metals in consequence of thermal treatment during electric resistance welding, the pressure of the electrodes on the work is, immediately after welding, increased to an amount greater than the tensile breaking stress of the metal. Thus, a hoop made of an aluminium alloy sold under the registered Trade Mark " Duralumin," having a tensile breaking stress of about 40 kgs. per sq. m.m., is welded under an electrode pressure of 5À5 kgs. per sq. m.m., the pressure being then increased to 55 kgs. per sq. m.m. The movable electrode 1 may be carried by a rod 16 connected by a lever 3 to a piston 5 operated by compressed air supplied from a pipe 12 through a reducing valve 13 and distributor 7. To apply the welding pressure, the distributor valve 8 is pushed down by a pedal to connect the supply to the lower end of the cylinder through the pipe 11a and an electromagnetically operated valve 15. The valve 15 is automatically raised after welding to connect the high pressure supply to the cylinder through the reducing valve 16a. A second electromagnetic valve 15a may be arranged in series with the valve 15 to prevent leakage which may take place in the valve 15 from affecting the welding pressure. The welding transformer has a tapped primary 18, one of the leads containing a contactor 24. The control circuit contains the relay coil 26, contactor 28, and switch 27, and a relay coil 29 having a high time constant is mounted in shunt across the contactor 28. The operating mechanisms for the valves 15, 15a are connected in parallel and connected to the supply through a contactor 30 coupled to the contactor 28 On operating the valve 8, the switch 27 is also closed and through the coil 26 closes the contactor 24 to effect the weld. The coil 29 is then energized to open the contactor 28 and close contactor 30 thus opening the welding circuit and operating the valves 15, 15a to admit the high pressure to the cylinder.

Filed: 1917-05-14
Abstract: 127,652. Morgan, J. S. May 14, 1917. Progressive evaporators.-Apparatus for concentrating sulphuric acid and other liquids consists of a tower or chamber containing basins E, Fig. 1, provided with lips F and so arranged that the acid drips from basin to basin, and is at the same time exposed to the action of products of combustion or hot air or other gases passing up the tower.

Title: Improvements in or relating to power indicating or measuring devices
IPC: G01L3/10
Filed: 1944-04-13
Abstract: 578,859. Electric indicating systems. SHEPHERD, G. R. (Westinghouse Electric International Co.). April 13, 1944, No. 6852. [Class 40 (i)] [Also in Groups XIX and XXXVI] A device for indicating or measuring the power output of a rotating shaft is characterized by a single magnetic flux producing electromagnetic unit comprising a stationary member having an electrical coil and a member rotatable with the shaft and responsive to the toraue and speed characteristics of the shaft for inducing a voltage in the coil indicative of the power of the shaft. The rotatable member comprises two axially displaced torque rings 7 and 9, Fig. 1, mounted on shaft 1 by means of non-magnetic bushes 13 and a central toothed member 17 also mounted on shaft 1 by means of a non-magnetic bush 19. The torque rings 7 and 9 each have axially extending fingers 7a and' 9a which are so positioned as to form the air gaps 6 and 8, Fig. 2, with the teeth 15 of the member 17. The stationary member 5 is of magnetic material and forms air gaps 24 and 26 with the torque rings 7 and 9. The member 5 has teeth portions 27 having windings 29 in series or in parallel and attached to an indicating instrument 31. Either the member 9 or the member 5 is a permanent magnet producing a flux flowing in the path shown, i.e., member 5, gap 26, member 7, finger 7a, air-gap 6, a tooth 15, air-gap 8, finger 9a, member 9, air-gap 24, member 5. When the shaft 1 is stationary or rotating at no load the flux path is unaltered but when the shaft is rotating at load circumferential distortion due to the transmission of torque takes place, the air gaps 6 and 8 are altered and a magnetizing force appears across the air-gaps 28 between the teeth 15 and the tooth portions 27 causing a flux to flow in the said tooth portions 27 thus generating a voltage in the winding 29 which is proportional to the speed of the shaft and to the torque transmitted, i.e., is a measurement of the power transmitted. In another embodiment not shown coils are used to obtain the magnetic induction instead of a permanent magnet. The faces of the teeth 15 and of the fingers 7a and 9a are shaped and dimensioned to compensate for relative changes of position of the component parts due to changes of temperature, end thrust of the shaft, and/or bending of the shaft.

Abstract: 560,712. Distilling alcohols etc. STANDARD ALCOHOL CO. May 30, 1941, No. 6930. Convention date June 14, 1940. [Class 32] Ternary diphase constant boiling mixtures having one constituent soluble in a liquid relatively immiscible with at least one of the other constituents of the mixture, e.g. a mixture of diisopropyl ether, isopropyl alcohol and water are separated by distilling the mixture to drive off the constant boiling mixture, condensing the vapours formed, separating the condensate into two phases, treating the upper phase in counter current with a solvent, e.g. water in part obtained from the lower layer, and separating the two phases which are thus formed, the phases being then treated separately to separate the individual components. A mixture obtained in the manufacture of di-isopropyl ether by the partial hydration of propylene in the presence of catalyst and comprising 81 per cent di-isopropyl ether, 12 per cent isopropyl alcohol and 6 per cent water is fed through line 1 to a tower 2 heated by steam injected through spray 3. The vapours formed are condensed in a cooler 5 and the condensate separated in vessel 7 into two layers the upper layer consisting of 93 per cent di-isopropyl ether, 12 per cent isopropyl alcohol and 0.55 per cent water while the lower layer comprises 1.5 per cent ether, 11.5 per cent alcohol and 87 per cent water. The lower layer is passed through pipe 8 into the bottom of a washing tower 9 filled with Raschig rings where it is treated in countercurrent with a spray of water, i.e. the watery lower layer admitted through line 26 and sprayer 10. The alcohol-free ether passes off through 11 to the tower 12 from which a binary mixture of ether and water is distilled off, the pure ether being recovered through line 18 and cooler 19. The condensate may be separated into two layers in vessel 17 the upper layer being returned to tower 12 or to the bottom of vessel 9 while the lower layer is mixed with bottom from the tower 8 and recycled to mix with the initial materials'in line 1.

As shown, the motors 10, 11 are geared to spools 14, 15 through friction devices each consisting of a pad engaged by a spring washer 1 adjusted by a nut 18. One terminal of each motor is connected to one limb 25 of the supply. The other terminals are connected to opposite ends of a resistance or inductance 28, a sliding tapping on which is connected to the other limb 30 of the current supply and is moved to control the relative motor torques. Two separate variable resistances or inductions with independent or connected tapping arms may be used.
