Patent GB-813429-A (GB)
Title: Process for dehydrating ethylene diamine
Filed: 1956-12-31
Abstract: Ethylene diamine is dehydrated by subjecting a current of aqueous diamine to treatment with an alkali metal hydroxide or an alkali metal hydroxide solution of at least 65 per cent wt. concentration. The vapours of an aqueous ethylene diamine (e.g. with a diamine content of from 75 per cent to the constant boiling mixture of 85 per cent) are passed upwardly through a fractional distillation column provided at the top with a layer of sodium or potassium hydroxide. The water in the vapours dissolves the alkali, which is constantly replenished.  Substantially anhydrous ethylene diamine vapours are removed from the top of the column and caustic alkali solution diluted to about 60 per cent by the extracted water from the bottom. Some diamine may be recycled to dissipate the heat of hydration of the alkali.  In an example 78 per cent aqueous ethylene diamine vapours at 119 DEG  C. are concentrated to over 99 per cent.  In a modification the solid alkali is replaced by 73 to 80 per cent hot alkali solution introduced at the top of the column.  The process may be conducted at, above or below, atmospheric pressure, e.g. from 200 mm. Hg. to 2 atmospheres.

Abstract: 1512134 Fuel injection pumps; starting IC engines STANADYNE Inc 27 Sept 1976 [14 Oct 1975] 40007/76 Headings F1A and F1B A fuel injection pump for an I.C. engine comprises bores 40, 40a from which, during engine starting, fuel is pumped to a distributer outlet 42 by plungers 34, 35 actuated by a common cam ring (46), a passage 48, 50 connecting the bores 40, 40a being closed by a valve 54 after start-up so that thereafter fuel is only pumped by the plungers 34. The valve 54 is loaded by a spring 58 to a position in which a ball 62 closes a passage 60 and a recess 52 completes the passage 48, 50. Fuel from an engine driven feedpump 24 is supplied to the passage 60 and acts to unseat the ball 62 when the output pressure of the pump 24 builds up to a predetermined value. Once the ball is displaced fuel enters a chamber 71 and acts on the larger surface of the valve 54 to move it leftwards thereby closing the passage 48 and opening the passage 50 to a drain chamber 76. To prevent fuel from the passage 48 from leaking into the chamber 71 and prematurely moving the valve 54, the chamber is connected to the drain chamber 76 by a passage 77 containing a throttle 74. Displacement of the valve 54 closes the passage 77 to prevent fuel loss from the chamber 71 during normal operation. Leaf springs (80 or 80a) are adjustable to control the maximum strokes of the plungers.

Patent GB-402083-A (GB)
Abstract: 402,083. Totalizator ticket-issuing apparatus. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. May 20, 1932, No. 14416. [Classes 106 (i) and 106 (iii).] In a ticket-printing machine, for example for totalizators, adapted to issue tickets of various values, these values are automatically converted by electrical means into multiples of a single unit and are so counted on a single-step counter. The invention is illustrated as applied to the machine described in Specification 367,354, the arrangements of which are consequently modified in the following respects. Instead of the separate value registers a series of contacts MCA, Fig. 7, are adapted to be operated by progressively-dimensioned cams MR1 ... MR5, Fig. 5, mounted on one of the lay shafts LS, Fig. 3. With one of the stakevalue keys KSV depressed therefore, one of the contact springs MCA becomes active so that when, during the first revolution of the main shaft, the contacts are closed a circuit is completed to a magnet EMC, this circuit being made at a point in the cycle corresponding with the leading end of the pertinent cam MR and therefore with the key value, and persisting for the remainder of the cycle. The magnet EMC through its armature AC, Fig. 3, engages a clutch CUTC having a number of teeth dc to co-operate with corresponding recesses in the fixed member BAC to ensure completion of the clutch engagement for the necessary fraction of the cycle. The clutch drives through gearing SSC the units element of the counter COC and also a cam MOC to close, during its rotation, a pair of contacts MON, in circuit through contacts k2 with relay P and keyrelease magnets KRM. The last operation of the counter in any cycle overlaps the second revolution of the main shaft and if the contacts MON should fail to close, the keys are not released and the relay P is not operated, so that its contact p5 (not shown) does not maintain the motor circuit and the machine consequently stops in an off-normal position.

Filed: 1961-11-10
Abstract: The outer skin of a nickel-phosphorus coating carried by a workpiece, such as the lining of a tank or other hollow container fabricated from one or more steel sheets joined together, is converted to a Sn-Ni-P layer containing 1-50% Sn, 46-93% Ni and 3-12% P by simultaneously depositing metallic tin upon the coating surface, preferably by reducing a compound of tin such as a stannous or stannic chloride or other halide on the surface heated to a temperature between the melting points of tin, e.g. 332  DEG C., and the Ni-P coating, e.g. 880  DEG C., and diffusing the tin into the outer skin, the tin being deposited at a rate not higher than that of diffusing the tin.  The reduction may be carried out with reducing gases containing 25-40% by volume hydrogen such as produced by cracking ammonia gas, e.g. at 930  DEG C., or mixing hydrogen and nitrogen, the gases first passing over the tin compound, e.g. SnCl2 heated to 480-500  DEG C., then on to the surface of the heated coating, e.g. at 630  DEG C.  Alternatively, cracked natural gas or heated anhydrous ammonia may be used as the gases.  With a Ni-P coating of composition 85-97% Ni and 3-15% P, the Sn-Ni-P alloy formed at a reaction temperature of 630  DEG C. during a time of less than 4 hours shows a single layer; with a reaction time of 4 hours or longer, three separate intimately bonded layers are formed, namely a first layer bonded to the inner Ni-P alloy portion and consisting of tin distributed in Ni-P alloy, a second layer consisting of Ni-P alloy distributed in tin, and a third layer of tin.  The coating is preferably at least 2 mils thick.  The initial Ni-P coating may be chemically deposited from a bath of the nickel cation-hypophosphite anion type, or electrodeposited and subsequently heat-hardened, e.g. at 400-630  DEG C. to produce microcrystals of Ni3P dispersed in a matrix of nickel.  For chemical deposition the workpiece must be formed of or have growth nuclei of catalytic material such as iron, copper, aluminium or alloys thereof, e.g. steels containing one or more C, Cr, Co, Si, Mn, Ni, Mo, Cu, brass, bronze including Si or P bronze, Be-Cu, Cd-Cu, Ni-Cu, and aluminium brass or bronze. If the workpiece is formed of Mg, Ti, Zr, Hf, it must be first treated by the method disclosed in U.S.A.  Specification 2,928,757.  U.S.A.
