Title: Improvements in or relating to a process for sweetening gasoline
IPC: C10G27/04
Filed: 1954-01-29
Abstract: Gasoline, at least one third of which consists of cracked naphtha, is sweetened by first washing with caustic alkali solution in the absence of oxygen to remove hydrogen sulphide and at least some of the organic sulphur compounds, and then contacting with air in the presence of an N, N1 - dialkyl - p - phenylene diamine and ammonia. The gasoline may be derived from thermal or catalytic cracking operations, or may be a blend of virgin and cracked naphthas provided the blend contains the prescribed amount of cracked naphtha.  The gasoline may have been subjected to a preliminary sweetening, employing for example the solutizer process, and the process of the invention then removes the residual mercaptan content of the gasoline.  The N, N1 - dialkyl - p - phenylene diamine employed may be N, N1 - di - n - butyl - p - phenylene diamene or N, N1 - di - sec. - butyl - p - phenylene diamine.  Apparatus is described in which the gasoline is mixed with caustic soda solution, the N, N1 - dialkyl - p - phenylene diamine is added to the mixture and spent caustic soda solution is removed.  The materials contacted are oxygen-free and a closed system is used to prevent any access of air or oxygen.  The caustic soda-washed gasoline is then mixed with aqueous ammonia and air is simultaneously injected into the gasoline. The mixture is allowed to settle for 1-3 days, whereupon aqueous ammonia separates as a lower layer and is returned to storage for re-use.  The gasoline layer is water-washed to free it from traces of ammonia and the wash water is treated to recover the ammonia.  In the examples, thermally and catalytically cracked gasolines, and blends thereof with each other or with virgin gasoline, are sweetened by treatment first with caustic soda solution in the absence of oxygen, and then with air in the presence of N, N1 - di - sec. - butyl - p - phenylene diamine and aqueous ammonia.  For comparison purposes, the application of the process to the sweetening of virgin gasoline is described.

Abstract: 1487685 Nibblers; stamping TRUMPF MASCHINEN AG 23 Jan 1975 [31 Jan 1974] 2952/75 Headings B3W and B3Q A nibbler or other punch 1 and a metal workpiece 4 are connected to an electrical source 7 via a circuit including a switch device such as a relay 9 so that in use, intermittent electrical contact is established between the push and the workpiece to intermittently actuate the switch device. A contact 10 of the relay 9 is in the circuit to a drive motor 11 of the workpiece feed and is spring loaded at 14 so that closing and opening the circuit including the workpiece when the punch enters and leaves the workpiece respectively opens and closes the circuit including the motor 11. The motor can be made to stop before the punch contacts the workpiece by means of a sleeve 17. As the punch leaves the workpiece, the sleeve is clamped to the punch and moves up with it against the action of a spring 16. On the downward stroke, the sleeve with its leading end at the position 21 actuates a proximity switch 22 on a fixed stop 19 to stop the motor while the punch is spaced by distance 23 from the workpiece. The switch 22 also causes the sleeve to be unclamped from the punch and the punch proceeds along to make a nibbling cut. As the sleeve is clamped to the punch when the latter leaves the workpiece, it is clamped closer to the free end of the punch and the feed drive motor 11 thus runs for less time, the thicker the workpiece.

Filed: 1938-02-02
Abstract: 500,458. Centrifugal hydro-extractors. BAILLY, A. Feb. 2, 1938, Nos. 3258, 3259, and 3260. Convention dates, Feb. 4, 1937, July 30, 1937, and Aug. 30, 1937. [Class 23] A centrifugal hydro-extractor has a perforated basket 3 in the form of a conical frustum secured to the shaft 4 by a flange 5 at the small end. Inside the basket is a meshliko drum 7 secured to the sleeve 6 on the shaft 4. On its outer surface the drum has parallel rings 8, 9, 10 with one or more staggered gaps 11, 12, 13 and projecting from its inner surface is an annular apron 14. The shaft 4 and sleeve (i are driven normally at different speeds through gearing 21, 19, 20 18 and the material for treatment is supplied by the tube 15 to the space behind the apron 14. It passes to the space between the basket 3 and the drum 7, and the liquid passes through the basket to the collecting trough, while the - remainder of the material tends to travel outwards but is arrested by the ring 8. It can however pass through the gap 11, and its outward travel is arrested by the ripg 9 until it can pass through the gap 12. The action is repeated at the ring 10. A suitable arrangement of gaps and control of the difference of speed between the basket and the drum will determine the time for which the material stays in the extractor. A number of gaps may be made in each ring, and the rings may be helices of very small pitch. Vanes 23, 24,25 are arranged between adjacent rings to prevent particles from adhering to the basket. In a modification either of the wheels 20, 18 is rendered active only when the clutch 26 is engaged. By disengaging the clutch, the drum 7 is released from the drive mechanism, and is driven by its engagement with the material in the basket. The basket may be formed of a number of conic frustra with different basic angles, or it may be a surface of revolution generated by a curved generatrix.

Title: Digital electric dividing apparatus
IPC: H03M7/08
Filed: 1958-02-04
Abstract: 866,571. Digital electric calculating-apparatus. MONROE CALCULATING MACHINE CO. Feb. 4, 1958 [Feb. 4, 1957], No. 3677/58. Class 106 (1). In apparatus for converting a number represented by a binary serial pulse train into decimal form, the number to be converted is stored in a memory unit 10 such as a magnetic drum track or a shift register and the contents of the unit 10 circulate via an adder/subtracter 12. A further memory unit 20 stores in binary form a power of ten, 10m, equal to the power of ten contained in the decimal equivalent of the capacity of the unit 10, assuming this capacity to be fully utilized. 10m is subtracted from the number to be converted in the adder/subtractor 12, and the remainder R passes a normally open gate 18 to re-enter the memory unit 10 and also to be compared by a comparator 24 with 10m. A timing pulse T0 enables gates 28 and 30 which pass a signal respectively according as R < 10m or R#10<SP>m</SP>. In the latter case a decimal counter 40 is stepped on by one digit and the subtraction process is repeated until R<10<SP>m</SP>. When R < 10m, a signal on a line 38 is adapted to transfer the counter reading to a display device 42 such as an electric typewriter. An output 46 from the display device zeroizes the counter 40 and sets a flip-flop 49 to produce a " times 10 " signal which opens gates 52 and 56, the gate 52 passing pulses representing the remainder R delayed by two pulse times by a delay 50. The resulting pulses representing 4R are added to pulses representing R in the adder/subtractor 12 which is conditioned for addition due to the absence of a signal on line 32. The output on line 17 thus represents 5R and is delayed by one pulse time at a delay 54, instead of passing via the gate 18, so that 10R is fed back to the memory unit 10. The above process is repeated until every decimal digit has reached the display device 42. The apparatus may be used more generally for dividing two numbers in binary notation to give a quotient in the decimal notation.
