Abstract: 902,848. Supply systems for welding arcs. SATURN INDUSTRIAL GASES Ltd. Oct. 1, 1959 [Nov. 7, 1958], No. 35859/58. Class 38 (4). An A.C. arc welding system having a spark discharge igniting circuit has a sensing device responsive to positive half cycles only to apply the spark discharge independently of the negative half-cycle condition. The welding arc voltage is sensed by a circuit connected across the electrodes 3, 4 comprising relay coils F, H, each connected in series with oppositely poled rectifiers 14, 12. On failure of the arc on positive half-cycles, the rise in voltage across the electrodes energizes through relay H, H 1  a spark discharge device 9 which applies its output to the electrodes. The other relay F, F 1 , F 2  when energized on negative half-cycles moves the phase of the sparks nearer to the beginning of each half-cycle through a device 10, and shunts a D.C. suppression circuit 6, 7, through a relay E, E 1 . In an alternative arrangement (Fig. 1, not shown), the relay coils F, H are normally energized from an impedance connected in series with the arc, and an interlocking circuit is provided between the relay coils F, H. Specification 705,164 is referred to.

Title: Improvements relating to locking means for retractable undercarriages of aircraft
IPC: B64C25/14
Filed: 1936-12-09
Abstract: 486,936. Aircraft landing-gear. DOWTY, G. H. Dec. 9, 1936, Nos. 36014/37,36015/37, and 36016/37. Divided out of 473,202. [Class 4] In a fluid-pressure jack-operated retractable undercarriage for aircraft, one or more locking members or latches coacting with elements on the fuselage or undercarriage radius rod or stay are operated in series with the stay, a lost-motion device being incorporated so that, in retracting or extending the undercarriage, the operation of the stay is preceded and /or followed by unlocking or locking of the latch in the necessary sequence. In the construction shown in Fig. 2, the wheel-carrying leg 20 is pivoted to the fuselage at 20A and maintained in extended position by a twopart stay 21, 22 controlled by a jack 23, a locking-pawl 27 having two notches 27A, 27B being pivoted on the part 21 and being actuated by a telescopic spring link 28 connected to a lug 24B on the end of the jack piston 24. The lug 24B has a slot in which a pin 25 on the part 21 engages with lost motion. If, from the extended position shown in full lines, the jack piston is moved inwardly, the initial movement of the lug 24B and link 28 causes the notch 27A to be disengaged from a pin 22D on the part 22, thus freeing the stay 21, 22 for folding. At the end of the retractive movement, the other notch 27B engages a pin 29A on a bracket 29 on the fuselage. Similarly, in extending the leg 20, the initial outward movement of the jack piston disengages the notch 27B from the pin 29A. In a simpler construction, Fig. 1 (not shown), the locking- pawl is single-acting and serves to lock the stay in an extended condition only, while in a further construction the jack piston co-operates with a bell-crank lever, and separate locking- pawls are provided for retaining the leg in its two extreme positions. If desired, the jack cylinder and piston may, as shown in Fig. 5, be incorporated in one part 52 of the stay 51, 52, the outer end of the piston moving in a slot 52A and being connected through a rod 55 to a link 56 which controls the locking-pawl 57. Specification 457,982 is referred to.

Abstract: 1,148,031. Controlling distillation. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 7 Aug., 1967 [9 Aug., 1966], No. 36082/67. Heading C5E. [Also in Division B1] The composition of a product stream from a distillation column 1, wherein the continuous fractionation of a feed mixture is being carried out, is measured by arranging two differential vapour pressure meters 29, 30 vertically apart in the column, and combining the output signals of the meters in a computing element 31, the output signal of which is recorded and/or used to control the column. The embodiment shown is for the separation of isopentane as top product from a mixture of isopentane, n-pentane and butane; in this application the output signals from meters 29, 30, which are disposed in the top section of the column, are combined in an adjustable ratio in a pneumatically operating addition/subtraction relay 31 which sends to recording device 32 a signal representing the percentage of n-pentane in the top product. Each meter measures the pressure-difference between the pressure prevailing in the column at the point of connection and the pressure of a sample of liquid, in the probe, which has the composition which the liquid on the tray in question should normally have. Two feed streams are introduced into the column-a straight-run pentane fraction through line 2, and the top product from the depentanizer of an alkylation unit through line 3. The vapour stream from the top of column 1 is passed to cooler 5, and the condensate is collected in accumulator 6. Part of the condensate is returned to the column as reflux through line 10, and the remainder is withdrawn from the system through line 9. Part of the bottom product (n-pentane) is pumped out of the system through lines 11 and 13, and the remainder is recirculated to the column through lines 14 and 16 via reboiler 15. The control of the column is effected by (a) pressurecontroller 17 which governs valve 18 in the cooling-water line of cooler 5, (b) flow-meter 19 which maintains the reflux constant, (c) liquidlevel controller 21 which governs the discharge of top product, (d) temperature-meter 24 which controls the flow of heating-medium through re-boiler 15, and (e) liquid-level controller 27 at the bottom of the column. In other embodiments, the computing element controls the flow of reflux or cooling-water. The feed-stream 2 may be passed through a preheater at controlled flow-rate. The following mixtures may also be separated: butane-isobutane, propanepropylene, ethane-ethylene, and hexanes from a gasoline fraction.
