Title: Improved method of cracking oil
Filed: 1931-04-28
Abstract: In processes for cracking oil in the liquid or vapour phase corrosion of the tubular heating unit by sulphuretted hydrogen formed in the process is prevented by mixing a small predetermined amount of air with the oils as they flow through the heating unit.  The amount of air added is too small to permit partial combustion and varies from 10 to 15 times the volume of the sulphuretted hydrogen which is found in the gas leaving the final condenser when the process is operated without adding air.

Title: Improvements in and relating to regulating and starting switch gear for electric motors and the like
IPC: H02P1/04
Filed: 1925-05-15
Abstract: 256,713. Turnell, H. G. May 15,1925. Regulating-switches; sparking-preventing. - In a step-by-step resistance-regulating switch having a double-armed main moving contact, an auxiliary switch or contactor is adapted to operate synchronously, with a rapid action and with abutting contact, when the leading arm is fairly over the fixed contact with which circuit is to be made. As shown in Fig. 1, the sliding main contact-membar has a leading contact 3 insulated from the arm 4, and a following contact 2. At one end these contacts are in continuous engagement with contact bars 1A and 1 which are connected with one another and disconnected by an electromagnetic contactor 20, energized synchronously with the movements of the main contact arm, by the engagement and disengagement of the upper end 25 of the arm 4 with auxiliary contacts 30 - - 33 located between the main fixed contacts 6 - - 9. Thus the leading contact 3 does not become a carrier of current. until it is fairly over one of the fixed contacts, and it ceases to be a carrier of current before it leaves such contact. The contactor may be mounted upon and incorporated with the moving switch arm. In the arrangement shown in Fig. 3, mechanical means comprising cam surfaces 10 - - 13 serve to raise and lower the leading arm 3 with a snap action so that it becomes a carrier of current only when it is fairly over a contact.

Title: Thrust-reversing means for a jet propulsion engine
Inventor: RAINBOW HORACE SINCLAIR
IPC: B64D27/02
Filed: 1956-04-27
Abstract: 806,038. Jet propelled aircraft. ARMSTRONG SIDDELEY MOTORS Ltd. April 15, 1957 [April 27, 1956], No. 12946/56. Class 4. [Also in Group XXVI] An aircraft jet propulsion engine thrust reversal means includes a nozzle movable axially away from the end of the jet pipe, and a plurality of segments pivoted to the nozzle for swinging movement to an operative position in which they form a conical baffle closing the nozzle inlet when the nozzle is in its downstream inoperative position, the nozzle being fast with a plurality of axially slidable rods carrying a series of thrust-reversal rings coaxial with the jet pipe and of curved cross-section concave upstream. Fig. 2 shows a jet pipe 10 supporting a wall 11 and a housing 12, on the forward face 20 of which are mounted jacks 15 having piston rods 14 mounting thrust reversal rings 13 and the nozzle 16, and jacks 22 having piston rods 23 passing through apertures in the rings 13 and pivoted to links 27, Fig. 6, pivoted to the baffle segments 24 which are hinged to the nozzle at 31. In the inoperative position, all the jacks are retracted, and the rings 13 lie inside the housing 12 and the segments 24 lie between the jet pipe 10 and wall 11. To reverse the thrust, the jacks 15 and 22 are extended, and the nozzle, rings, and segments move bodily downstream. The pistons 23a of jacks 22 then abut stops, but the pistons 14a of jacks 15 continue moving and the relative movement between. the nozzle and rods 23 swings the baffle segments through the position of Fig. 6 to that of Fig. 2. The jet pipe is cut away as at 24a, Fig. 2, to accommodate this swinging. On reverting to normal operation, the reverse sequence takes place. Fig. 7 shows a hydraulic control circuit comprising a reservoir 38, pump 39 and a valve 32. With the valve in the position shown, pressure fluid passes through conduits 41, 42 valve bores 44, 45 and conduits 46, 47 to the jacks 15 and 22. These extend equally until piston 23a abuts its stops, when piston 14a alone moves to swing the segments. The jacks exhaust through conduit 49 and a valve bore 60. On reversing the valve by a lever 33, pressure fluid passes through conduit 40, valve bore 43, and conduit 49 to return piston 14a jack 15 exhausting through valve bore 50. Jack 22 is not free to exhaust through valve bore 51, however, until piston 14a has moved sufficiently to open a valve 34 in conduit 52. By this time the baffle segments have been retracted, and the nozzle, rings and segments move upstream together.

Filed: 1975-03-27
Abstract: 1492848 Memory circuit GARRETT CORP 27 March 1975 [1 April 1974] 12948/75 Heading G4M [Also in Division F1] A fluidic memory circuit contains an input circuit 26 receiving pulses for counting on line 27 and having two outputs feeding respective control nozzles of a bi-stable. The two outputs of the bi-stable feed respective control nozzles of the input circuit to ensure that successive pulses provide pulses alternately on the outputs so that outputs 30, 40 of the bi-stable alternately carry pulses. The outputs 30, 40 feed a latching indicator 12 which is moved by a pulse from the appropriate output and is retained in either of two positions. The indicator carries indicia visible through a window (Fig. 3, not shown) and has an arm carrying an obstructor 55 which ensures that the circuit returns to the same state if the fluid supply is shut off and restored. Fluid is supplied at sources 17 and in unit 13 a pulse when fluid is connected is supplied via delaying restriction 68 to a control nozzle to direct fluid into output 56. The pulse also passes via restriction 69 and delay 70 to stop fluid from flowing into output 56 so a pulse of predetermined length is produced on output 56. This is fed to the line 45 or 46 which is not blocked by obstructor 55 and feeds a NOT gate which feeds a respective one of the control nozzles of the bi-stable to ensure that fluid flows to the output that would move the indicator to the position it was in when the fluid supply was shut off.

Abstract: 1,185,994. Welding by fusion. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 7 March, 1968 [20 March, 1967], No. 13022/67. Heading B3R. Tube to tube plate and like joints are welded internally by a gas-shielded consumable electrode arc-welding gun having a head 2 rotated to guide the electrode 3<SP>1</SP> around the joint X. The head 2 has a body 1, to which the electrode 3<SP>1</SP> is guided by a tube 4, and an insert 11 fitting into a slot in the body 1. A groove 12 in a curved surface of the insert 11 serves to direct the electrode 3<SP>1</SP> to the joint. The body 1 has an insulating coating or insulating spacers. Gas is fed through apertures 6 to the welding zone. In a modification the body 1 is in the form of a curved electrode guide tube which may be surrounded by a curved gas nozzle. The electrode provides about 60% of the weld deposit. Carbon steel workpieces are welded using an electrode providing a weld of lower carbon content, e.g. 0À08-0À12% C. Austenitic stainless steel workpieces are welded, using an electrode which provides a weld containing 2-15% ferrite. Reference is also made to workpieces of killed, semi-killed and rimming steel, creep-resistant steels, e.g. 1% Cr, ¢% Mo; 2“% Cr, 1% Mo; 5% Cr, ¢% Mo, and 12-14% Cr steel, aluminium, titanium, nickel, copper and their alloys. Welding may be by dip transfer using carbon dioxide or 80% argon, 20% carbon dioxide, argon-shielded spray transfer or argon-shielded pulsed arc. Reverse or straight polarity may be used. The workpieces are spaced and a gas backing at a desired controlled pressure or a non-consumable backing in the form of a ring, which may be split, of ceramic or ceramic coated steel, is used. A tube plate may be formed with stub tubes or annular recesses serving to locate rings 62, Fig. 6, serving to support the backing ring and to align the tube 8 with the plate 7. A shoulder 61 on the tube or a detachable gauging ring or clamp may contact the end of the supporting ring 62 which thereby ensures the correct welding gap. Alternatively, a thin consumable aligning insert 151, Fig. 15, may be used. The supporting ring 62 may be dispensed with and the backing ring 182, Fig. 17, may be shaped to engage and align the workpieces and to form a weld fillet where the adjacent parts of the tube 8 and tube plate 7 are of different dimensions or to shape the back of the weld to form a rounded bead.

A precision balance e.g. an analytical or micro-balance, comprises a measuring member, i.e. a beam 5 pivoted about a point M, and carrying a measuring plate 9 with a scale of index marks, and a reading device e.g. an optical projection device 10, for part of the scale,for determining the last places of decimals of mass with the aid of the index marks and in accordance with the inclination. of the beam 5, the index marks being arranged along a curve K represented by the formula R α  = R o  (i + k) E o  / kE o  + Eα where E 0  is the angular sensitivity of the balance at a predetermined starting position and R o  is the radius vector of the curve K at this position, E α  and R α  being corresponding values with the beam at an inclination α, and K being a constant. The index marks are numbered, the numbers being arranged on a circular arc T, and the arrangement of index marks on the curve K means that consecutive marks are always spaced on an arc which subtends a constant angle at a point a distance 1/k R o  from the curve K along the radius R o . Thus by projecting a series of equiangularly spaced lines (not shown) emanating from this point on to the field of view of the device 10, values of mass intermediate the index marks may be read off directly.
