Filed: 1937-07-06
Abstract: A tubular furnace for heating fluids, e.g. hydrocarbon oils, comprises a rectangular heating and combustion zone defined by side walls 1 and end walls (not shown) and provided with an additional wall 9 against which the gases from burner ports 8 are directed in an upward direction so as to heat vertical <PICT:0498477/III/1> banks 13 of horizontal tubes 12 by radiant heat from the wall 9 and by reflected heat from the walls 1, the furnace gases then passing over a second bank of tubes 18 situated in a zone substantially vertically above the combustion zone and heated by convection from the residual heat of the furnace gases.  In a modification, the wall 9 constitutes one of the outer walls 1 of the furnace, while in a further modification the furnace gases are directed upwardly over the inner surfaces of the furnace walls 1 so as to heat by radiation banks of tube arranged on opposite sides of the central wall 9.  As shown in Fig. 1, the furnace is of the " double-end " fired type comprising two separate combustion zones 10, 11, and this construction may be utilized to subject two separate streams of oils to different heating conditions.  Examples are given of different methods of connecting up the tube-banks 13 ... 18 in any desired sequence to obtain the most advantageous heating conditions for the particular oil under treatment.  The convection tube-bank 18 is located in a zone 3 defined by side walls 4 connected by sloping walls 2 to the furnace wall 1 and is protected from radiant heat by a bank 17 of staggered tubes arranged wider apart than the tubes of the bank 18.  The heated fluid then flows through banks 15, 16 arranged parallel to the sloping walls 2 before entering the banks 13, 14. Specification 328,064, [Class 32], is referred to.

Title: Improvements in or relating to railway signalling installations
IPC: B61L23/22
Filed: 1953-07-09
Abstract: 737,146. Axle-counter supervised railway signalling. SIEMENS & HALSKE AKT.- GES. July 9, 1953 [July 21, 1952], No. 19124/53. Class 105. In a single track two-way signalling installation with axle counter supervision of the signals, counters are arranged at the ends of each section and are interconnected by conductors along the sections and are so connected to said conductors to receive counting-in and counting- out impulses in dependence upon the direction of travel currently permitted. In Fig. 1 contacts 111-115, 211-215, 221-223, 314, 315 and 321-323 are shown set so as to establish east-bound travel and connect the counting- in mechanism E and the counting-out mechanism A of the counter 42 at counter point I to be operated respectively by the wheel-operated contacts 101, 102 and, via line conductors Lll, L12, L13 and contacts 211, 212, 213 by the contacts 201, 202 at counting point II. Counter Z1-2 controls the signal S1-2. Counter Z2-3 is operated similarly for east-bound travel over section II-III. Similarly for west-bound travel counter Z3-2 at point III and counter Z2-1 at point II are operated, the abovementioned contacts 111-115 &c. having been reversed, for example from the interlocking frame, by means of a direction lever or relay. At the point II contacts 201-202 give counting pulses to counting out motor A of counter Z1-2 to clear the signal for the first section I-II, and counting in pulses to counter Z2-3 to denote occupation of section II-III. For reverse travel direction counting impulses commence at point III at contacts 302-301 to operate the counting-in mechanism E of counter Z3-2. At point II contacts 202, 201 simultaneously operate counting-out mechanism A of counter Z3-2 and counting in mechanism E of counter Z2-1. In a modification only one axle counter, with motors running reversed for opposite directions of travel, is used at point II, functioning as a counting-in device for section II-III for East-bound traffic and as a counting- in device for the section I-II for West-bound traffic, the control of the two signals S2-1 and S2-3 being made dependent on the result of the counting operation for the particular travel direction through contacts 209, Fig. 2 (not shown) set for the particular direction. In another modification a simple current loop transmits the counting impulses having characteristic features such as wave trains of different frequencies, or impulses of different polarities for the opposite directions of travel and the counters respond only to a respective impulse characteristic feature, e.g. differently polarized receiving members connected in series or parallel pairs across the loop conductors.

Title: Improvements in or relating to corrosion inhibitors
IPC: C23F11/04
Filed: 1957-06-18
Abstract: Di-substituted amides useful as corrosion inhibitors (see Group II) are made by reacting amines with acids or acid chlorides in an inert atmosphere of e.g. nitrogen.  Specifically, diisopropylamine is heated with palmitic, oleic or linoleic acid or with lauroyl chloride to form, respectively, N-diisopropyl-palmitamide, -oleamide, -linoleamide, and -lauramide; and lauroyl chloride is heated with N-ethylcyclohexylamine or N-ethylhexylcyclohexylamine to form, respectively, N-ethylcyclohexyl- and N-ethylhexylcyclohexyl-lauramide.  Pyridine, a tertiary amine or an inorganic alkali may be added to absorb hydrochloric acid liberated from the reactions involving lauroyl chloride.ALSO:As corrosion inhibitors are used N-substituted amides of the general formula R1-CO-NR2R3 where R1 is an alkyl or alkenyl group containing 7 or more carbon atoms, R2 is an alkyl or alkenyl group containing 2-18 carbon atoms, and R3 is a hydrogen atom or an alkyl or alkenyl group containing 2-18 carbon atoms.  The sum of the carbon atoms in R2 and R3 is preferably not more than 24.  Amides given by way of example are N-diisopropyl-lauramide, -palmitanide, -oleamide, -linoleamide, -caprylamide, N-ethylhexylcyclohexyl lauramide, N-ethylcyclohexyl lauramide, and N-dodecyllauramide.  The amides are particularly useful in inhibiting the corrosion of zinc and may be employed in conjunction with (i) acids used to descale and clean galvanised steel, (ii) acids in contact with zinc elements of circulating systems, as in condensers or evaporators, and (iii) the underground acidizing of wells.  They are preferably applied to an inert carrier such as silica gel, clay, kieselguhr or carboxymethyl cellulose if used with a solid such as sulphamic acid, Other specified acids &c. are sulphuric and hydrochloric, and sodium hydrogen sulphate.  The addition of non-ionic wetting agents to the compositions is stated to be beneficial.
