Title: Process for the manufacture of ethylic alcohol and other products from coal distillation gases
IPC: C07C29/06
Filed: 1928-12-29
Abstract: 303,176. Compagnie de Bethune. Dec. 29, 1927, [Convention date]. Ethyl hydrogen sulphate; ethyl alcohol; ethyl ether; glycol.-In the production of ethyl alcohol and other derivatives of ethylene such as glycol and ether, coal distillation gases are treated to separate a mixture of ethylene and ethane, the ethylene is absorbed in sulphuric acid and the ethane is heated to produce ethylene and hydrogen which are returned to the raw gas so as to recover the ethylene in the further progress of the process, and the ethyl hydrogen sulphate is then treated to obtain the desired product. The coal distillation gas is liquefied for instance at a temperature of-150‹ C. in an apparatus A and the liquid is fractionated in a column B, the fraction containing the ethylene and ethane being led to a vessel C in which it is treated with sulphuric acid. The unabsorbed portion, mainly ethane, is passed through a tube D at 600-800‹ C. to produce ethylene and hydrogen which are led back to the liquefying apparatus A. Specification 338,358, [Class 64 (i), Heating liquids &c.], is referred to.

Title: Spiro-(cyclohexane-1:2-coumarans) and a process for their manufacture
IPC: C07D307/94
Filed: 1961-10-26
Abstract: The invention comprises compounds of the general formula I <F\1> wherein R represents an alkyl group containing 1 to 5 carbon atoms, X1 and X2 each represent a hydrogen or hydrogen atom and >Y represents a >CHOH or >C=O group.  These 3-oxo-spiro-(cyclohexane - 11: 2 - coumarans) may be prepared by heating to 30 DEG  to 125 DEG C. a 1-aryl-oxo - 4 - benzyloxy - cyclohexane - 1 - carboxylic acid of the general formula II <F\2> or a chloride, or bromide, or primary, secondary or tertiary amine salt thereof, or a l-aryloxy-4-hydroxy - cyclohexane - 1 - carboxylic acid of the general formula IIa <F\3> with boron trifluoride or a boron trifluoride organic complex compound, and, when an amine salt is employed as reactant, debenzylating the resultant product, and, if desired, oxidizing the hydroxyl group in the 41-position of the 41 - hydroxy - 3 - oxospiro(cyclohexane-11: 2 coumaran) so obtained from any of the above reactants to an oxo group.  It is preferred to perform the ring closure reaction in the presence of a solvent or diluent, especially one of those which form complex compounds with boron trifluoride and most preferably dialkyl ethers and carboxylic acid alkyl esters.  A particularly preferred boron trifluoride organic complex is boron trifluoride diethyl etherate. The debenzylation of the 3-oxospiro-41-benzyloxy-(cyclohexane - 11: 2 -coumaran) formed in the first step when employing an amine salt reactant may be effected by catalytic reduction. The oxidation of the 41-hydroxy-3-oxospiro (cyclohexane-11:2-coumarans) may be effected with the aid of compounds of hexavalent chromium, especially a suspension of a chromium trioxide-pyridine complex in pyridine.  1 - Amyloxy - 4 - hydroxy - cyclohexene - 1 - carboxylic acids of the formula IIa may be prepared by, for example, reductive debenzylation in the presence of a catalyst of the corresponding 1 - aryloxy - 4 - benzyloxy - cyclohexane - 1 - carboxylic acid of the formula II.  1 - Aryloxy - 4 - benzyloxy - cyclohexane - 1 - carboxylic acids of the formula II may be prepared by the reaction of a phenol of the formula <F\4> with 1 - trichloromethyl - 4 - benzyloxy - cyclohexan - 1 - ol in the presence of an alkali.  1 - Trichloromethyl-4-benzyloxy-cyclohexan - 1-ol may be prepared by the reaction of benzyloxy-cyclohexan-1-one with chloroform in the presence of an alkali and with the use of an appropriate diluent, preferably formaldehydedimethylacetyl, at - 30 DEG  to 0 DEG  C.

Title: Improvements in and relating to automatic weighing and delivery devices
IPC: G01G13/30
Filed: 1930-12-23
Abstract: 362,702. Automatic-feed weighers. PASQUIER, A., 1, Rue Deves, Neuilly-sur- Seine, France. Dec. 23, 1930, No. 38793. Convention date, Dec. 28, 1929. [Class 143.] An automatic-feed weigher for loose and powdered materials comprises a feed hopper 1, Fig. 1, having a relatively small outlet 2 slightly inclined to the vertical, the feed from the outlet being controlled by an oscillatable plate 3, the oscillations of which decrease in amplitude to decrease the rate of feed as the material accumulating in the weighing- receptacle approaches the predetermined weight. The feed plate 3 is mounted on a vertical blade spring and is oscillated by an alternating current solenoid D, Fig. 9, into the energizing circuit of which a resistance R is inserted step by step as a contact plate 14 on the weighbeam B disengages the contacts 8 .. 12 during the downward movement of the weighing receptacle W. When the equilibrium position is reached and the beam has ceased to oscillate so as permanently to break the contact 12, current ceases to flow through a wire 20 that thereupon contracts and breaks a contact 23, 24 to de-energize a solenoid 25 and allow a core 26 to fall on to and depress the weighbeam. In the event of an overload entering the weighing receptacle, a contact 28, 29 is closed while the wire 20 is still hot and alarms such as a red lamp and a bell are operated. The weighing receptacle is triangular in shape and has a discharge-gate 30 that pivots about its fulcrum 31 under the weight of the material when a toggle linkage 33, 34 is upset by the abutment of the link 34 with a stop 38 during the tilting of the beam. The gate may return under its own weight or may be held open by a weighted arm 39 until it is forcibly closed during the upward movement by the engagement of a projection 40 with a stop 41.

Title: Improved blending apparatus
IPC: B01F15/04

Abstract: 1,010,448. Mixing liquids in flow. MOBIL OIL CO. Ltd. Nov. 10, 1961 [Nov. 11, 1960], No. 38893/60. Heading B1C. In a system for blending liquid there is a positive displacement pump for each fluid, at least one of which is driven through variable speed gears controlled by a device responsive to a property of the mixture whereby the ratio of the constituents is kept constant ; and an overriding variable speed gearbox adjusts the speed of all the pumps under control of a flowmeter at the outlet of the mixture. As shown in an apparatus for blending oils, pumps 2a, 2b draw the constituents from pipes 1a, 1b and discharge them through pipes 4a, 4b to a mixing chamber 8 and outlet 3. The pumps 2a, 2b are driven by a motor 9 through fixed ratio gears 11 and gearboxes 12, 13 of which the box 12 is variable and controlled through a connection 15 by a device 14 (which may be a viscosity meter, density meter, colorimeter or Geiger counter) connected to the outlet pipe 3. In the event of the flow rate of the mixture being altered by adjustment of the outlet valve 26, the flowmeter 16 acting through the connection 17 alters the setting of the over-riding variable speed gearbox 10 to vary the speed of both pumps 2a, 2b while maintaining the ratio of their speeds unchanged. A dangerous rise in back pressure due to sudden closure of the valve 26 is obviated by the relief by-pass valves 27a, 27b. Automatic variable orifices 18a, 18b equalize the input pressure of the constituents. Specification 916,493 is referred to.
