Title: A process for the manufacture and production of hydrocarbons
IPC: B01J23/70
Filed: 1927-05-09
Abstract: 271,452. I. G. Farbenindustrie Akt.- Ges. May 22, 1926, [Convention date]. Hydrocarbons and their oxygen derivatives are produced by the interaction of oxides of carbon with hydrogen, at ordinary, reduced or increased pressure, in the presence of catalysts which consist of or contain iron, cobalt, or molybdenum, prepared by the thermal decomposition of the corresponding carbonyl. The metal may be used in the form of the resulting fine powder, or deposited upon a carrier such as active silica, but preferably in the form of flakes such as are obtained by the thermal decomposition of the carbonyl vapour in an open space as described in Specification 269,677, [Class 72, Iron &c.]. Mixtures of the metals may be used, and other substances, such as difficultly-reducible oxides, may be present. Furthermore, the oxides produced by combustion of the carbonyl may be employed for the production of the catalysts. According to the example, equal volumes of carbon monoxide and hydrogen are passed through a furnace heated to 250 C. filled with iron flakes obtained by the decomposition of iron carbonyl vapour diluted with carbon monoxide; on cooling, hydrocarbons separate which are useful as fuels, solvents and lubricants. When the yield falls, the catalyst is withdrawn and fresh quantities formed by passing iron carbonyl vapour into the reaction chamber which is temporarily raised to a higher temperature. Specification 20488/13 also is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes the use of nickel, and of tho oxides produced by the combustion of the carbonyls, and the hydrocarbon derivatives obtained are not limited to oxygen derivatives. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to pumps
IPC: F04C15/00
Filed: 1938-04-27
Abstract: 514,120. Rotary pumps; stuffing - boxes ECLIPSE AVIATION CORPORATION. April 27, 1938, No. 12592. Convention date, April 29, 1937. [Classes 110 (ii) and 122 (v)] A rotary or other type of reversible air pump uses the pressure on the delivery side to prevent lubricating oil from creeping up the shaft 3 into the chamber 17 from the driving motor. Passages 21, 22 lead to pump inlet or discharge ports 13, 14. If 14 is acting as the discharge port, air under pressure' forces down ball valve 26 and places the chamber 17 under pressure, the valve, 25 being pressed on to its seat, thus preventing oil passing to the suction port 13. When the pump is reversed, valve 25 opens and valve 26 is closed. Lubricating oil under pressure enters, a port 38 and is fed from an annular chamber 40, through a passage 44 to a hole 51 in a ring 46, once per revolution of the latter. Lubricant is thus fed to the pump by way of a recess between the ring 46 and a sleeve 41. The oil flow may be controlled by varying the oil pressure, the size of .the passage 39 or recess 51, or by varying the springs 48.

Abstract: 1,218,283. Furnace control systems. UNITED STATES STEEL CORP. 15 March, 1968 [22 March, 1967; 5 June, 1967], No. 12817/68. Heading F4B. [Also in Divisions C7 and G3] In a process and apparatus for continuously annealing metal strip the latter passes through a furnace having heating, holding, and cooling chambers; the strip temperature is sensed as it leaves the heating chamber and its speed adjusted to maintain that temperature at the desired level, while the temperature of the coolant supplied to the cooling zone is adjusted to compensate for the change in strip speed. This compensation may be effected by sensing the strip temperature as it leaves the cooling chamber and correspondingly adjusting the heat supplied to the coolant. Additionally the strip temperature may be sensed near the exit of the holding chamber and the supply of heat to that chamber modified as necessary. The strip may be annealed in a controlled atmosphere, such as a nitrogen-hydrogen mixture. As illustrated, heating zone 10 and holding zone 12 are heated by radiant tubes 14 and 16 by burners fired which are under the control of temperature sensing devices 33 and 40. Strip temperature is sensed by radiation pyrometer 39 which through a potentiometer circuit controls the speed of motor 32 operating drive bridle 30. Strip temperature is also sensed at 41 thereby controlling the heat input to tubes 19 in conduit 18 through which coolant flows to pipes 17 in cooling zone 13. In a modification, heating zone 10 is subdivided into two sections; the first is temperature controlled as previously described, while the heat supply to the second and shorter section is controlled from sensor 39 through a system which acts only after a time delay and to large temperature changes.
