Title: Improvements in the manufacture of hydrocarbons by reaction between carbon monoxide and hydrogen
IPC: C07C1/04
Filed: 1937-08-05
Abstract: 500,264. Hydrocarbon synthesis; catalysts. DREYFUS, H. Aug. 5, 1937, No. 21623. [Class 2 (iii)] [Also in Group III] Hydrocarbons are produced by the catalytic reaction of carbon monoxide and hydrogen, the absolute pressure in the reaction zone being normally above 0À5 atmos. but periodically reduced to below 0À5 atmos. Reaction may be effected at about atmospheric pressure or above until the activity of the catalyst decreases, the pressure then being reduced to 0À25-0À1 atmos. or below until the catalyst recovers, the flow of reaction gases being either continued or interrupted. In the latter case, a stream of inert gases or vapours, e.g. nitrogen or steam, is preferably maintained. The catalysts, apparatus, temperatures and other conditions of working are those described in Specification 496,292. In examples: (1) carbon monoxide with twice its volume of hydrogen and with or without 3 times its volume of steam or carbon dioxide is passed at 1 atmos. over a cobaltthoria catalyst at 180‹ C. When after some hours the proportion of hydrocarbons in the exit gases falls appreciably the pressure is reduced to 0À1 atmos., usually for a relatively short time, to reactivate the catalyst. Most of the hydrocarbons are condensed from the exit gases which are recycled with fresh reactants; (2) reaction is effected as in (1) using steam as diluent, the flow of reactant gases being interrupted and only steam passed during the activating period. Specification 465,157, [Group III], also is referred.

Title: Improvements relating to automatic control systems employing reversible motor regulators
IPC: F23L15/02
Filed: 1937-08-10
Abstract: 502,175. Automatic control systems. LINDBERG ENGINEERING CO., Inc. Aug. 10, 1937, No. 22025. Convention date, Aug. 22, 1936. [Class 38 (iv)] Temperature.-In a system for controlling a physical or chemical condition in a chamber by varying the rate of flow of a conditioning medium, a control member 39 is moved in either direction by an electric reversible motor 11 to modify the condition in the chamber towards a predetermined range and a limit switch 33 is provided, the position of which determines the setting of the control member 39 at which the motor 11 is stopped. The motor 11 is operated in response to variations of the condition from a predetermined value and an auxiliary electric reversible motor means 12 responsive to variations above or below a predetermined range adjusts the position of the limit switch 33 in an amount and direction dependent on the time and direction the auxiliary motor 12 is operated. In a heat-treating furnace, temperature is maintained constant by a thermal element 43 controlling a relay 46 having a central zero and " high " and "low" contacts H and L which control a relay 60 governing the operation of a reversible motor 11 which operates the burner valve 40 through a lever 14 and link 38. The permissible opening of the valve is controlled by a stop 37 on the lever 14 which engages a limit switch 33 and opens the circuit of the motor 11. The switch 33 is mounted on a gear 15a coaxial with the motor shaft 13 and is adjusted in either direction by drive through a gear 32 from one or other of two motors 12a, 12b controlled from the relay 46. These motors cause movement of the gear 15a at a slower rate than the lever arm 14 is moved by the main reversible motor 11. The motors 12a or 12b are operated as long as the temperature is above or below a range of values determined by the setting of the contacts H, L. The motor 11 is operated in one direction or the other by the relay 60 when the temperature is above or below the value determined by the position of the contact H. A pointer 68 operated from a worm 21b on the shaft of the motor 12 indicates the position of the switch 33 and percentage opening of the valve 40. The lower limit of swing of the lever 14 is controlled by a fixed switch which de-energizes the motor 11. The limits of movement of the limit switch 33 may be set and adjusted by stops 72, 73 against which the pointer 68 abuts. The gear 32 &c. is driven from the motor 12 through a slipping clutch 28 and the position of the gear 15a and switch 33 may be adjusted by a knob 23 on the worm 21b.

Title: Improvements in or relating to the continuous casting of metal bar, strip or like stock
IPC: B22D11/06
Filed: 1949-08-29
Abstract: 668,338. Continuous casting-machines. NEVILL, C. W. Nov. 29, 1950 [Aug. 29, 1949; Feb. 3, 1950], Nos. 22443/49 and 2895/50. Class 83 (i). Metal bar, strip or like stock is cast by pouring molten metal into an annular trough rotated at such a speed that the metal solidifies in less than one revolution and is continuously stripped during the rotation of the trough. In one form, Figs. 1 and 2, molten metal is poured at 13 into an annular trough 4 supported in the rim of a horizontal wheel 1 ten feet in diameter and driven through gearing in the direction of the arrow R. Adjacent the pouring station the trough is cooled by water jets 8 directed through an opening 7 in bottom of the rim. A fixed dam 12 prevents a back flow of molten metal. Opposite the pouring point the cast strip is removed from the trough by a stripper 6. The upper surface of the metal may be shaped by means of a roller projecting into the mouth of the trough. In a modified form, Figs. 3 and 7, intended to prevent spoiling of the metal surface by gas bubbles 15, the trough is inclined to the horizontal and in the liquid zone, the open side of the trough is closed by a slipper 16 pressed into engagement with the trough by springs 17. Both the slipper and the underside of the trough are water-cooled. A tubular framework 35 adjacent the wheel carries a cross beam 34 which supports the pouring funnel 13 for the metal, a pipe 26 for supplying coolant, a stripper blade and the water-cooled slipper. A modified form of slipper and support, shown in Fig. 9, comprises a roller carriage supported from the beam 34 and pressed against the wheel by a leaf-spring 37, and guided by means of ridges 50 abutting the sides of the rollers 42. The underside of the slipper carries an arcuate member 45 depending into the trough 4 and serving to determine the shape of the upper part of the casting. Fig. 11 shows a slipper shaped to form a groove in the casting.
