Title: Improvements in or relating to variable area propulsion nozzles
Inventor: HOLIDAY JOHN BERTRAM
IPC: F02K1/12
Filed: 1958-11-12
Abstract: 932,805. Jet-propulsion nozzles. ROLLS-ROYCE Ltd. Nov. 12, 1959 [Nov. 12, 1958], No.36453/58. Class 110 (3). In a jet-propulsion nozzle having a convergent-divergent outlet, means are provided in the convergent-divergent portion of the nozzle to vary the configuration thereof by admitting air into the nozzle to prevent expansion of exhaust gases in the divergent portion so as to give the effect of a convergent nozzle. The convergent portion of the nozzle is formed by flaps 22, pivoted at their upstream ends and having ribs 26 adapted to support a rotatable roller 30 on a spindle 28. The roller 30 bears against an annular actuating member 32 which is moved axially by pneumatic rams 34. When the rams are withdrawn, the actuating member 32 swings the flaps 22 to form an annular passage 38 and links 33 raise closure members 42 in the fairing structure 18. Air admitted through ports 40 is drawn into the nozzle through the passage 38 by the ejector effect of the exhaust gases. When the rams 34 are extended the exhaust gas pressure causes the flaps 22 to close the passage 38. Instead of the ports 40, an inlet near the compressor inlet may be provided or air may be drawn from the compressor. The flaps 22 may be in the divergent portion of the nozzle and the walls of the convergent portion fixed. Alternatively, the convergent portion may be of square cross-section with one wall pivoted about its upstream end so that when pivoted towards the axis of the nozzle a gap is defined between its downstream end and the upstream end of the divergent portion.

Filed: 1928-12-11
Abstract: 309,119. Straub, J. April 5, 1928, [Convention date]. Bleached products ; treatment by damping; treatment by heating treating with solid substances. - Flour and other milling products are mixed with a small amount of a liquid mixture of organic peroxides or a liquid di-aroyl peroxide. The peroxide or the mixture may be mixed with the flour in a solid state and then brought to the liquid state by the addition of substances that lower its melting point or retard crystallization and, if necesary, moderately warming the mixture. The distribution of the reagent throughout the flour may be effected by spraying into the flour an emulsion of the liquid reagent in water with or without stabilizing colloids, ammonium salts, or organic nitrogen compounds of basic character, or adding to the flour a dry mixture of the liquid reagent with a mineral powder such as kieselguhr or a vegetable powder such as rice starch. Peroxides normally solid may have substances such as benzoyl anhydride or benzo-phenone added so that they can be used in the form of a supercooled liquid. Specific examples of eutectic mixtures of peroxides are given. Specifications 102,967, 186,571, and 309,118 are referred to.

Title: Improvements in tenoning machines
IPC: B27F1/04
Filed: 1932-12-29
Abstract: 404,456. Tenoning-machines. SCHROFF, A., 22, Keplerstrasse, Ulm, Germany. Dec. 29, 1932, No. 36804. [Class 145 (i).] A tenoning-machine, especially for cutting wide tenons in a single operation, comprises two pairs of cutting tools, one pair being mounted above, and the other pair below, the path of the work. Each pair of cutters c, d is mounted on an arm e which pivots on a carriage p about the shaft f of one cutter which is driven by a motor g ; the second cutter d is belt-driven. The two discs of each pair overlap in the direction of the path of the work, so as jointly to cut a wide tenon, the width of which is adjusted by rotating the arm e by means of a hand-wheel n and worm o. Each arm is adjustable independently of the other, so that the width x of tenon cut on the upper surface may differ from that, x<1>, cut on the lower surface of the work, as shown in Figs. 6 and 7. Each arm is vertically adjustable independently of the other so as to vary the thickness of tenon, by a screw-threaded shaft r rotated by handwheel s and worm t. For jointly adjusting the arms e, the shafts r can be coupled together by a toothed disc v splined to one shaft, and movable by lever w to engage a similar disc fast on the other shaft. The cutters c, d may be cylindrical or bevelled so as to produce undercut tenons.

Title: Machine for individually hardening the teeth of toothed wheels
IPC: C21D9/32
Filed: 1966-08-17
Abstract: <PICT:1092024/C6-C7/1> In an apparatus for individually hardening the teeth of toothed wheels by means of an inductor or burner, indexing of the turntable supporting the workpiece is controlled by a photo-electric device which senses the location of the teeth and the current emitted by which changes abruptly towards the end of each step, this change causing the driving motor to be stopped. The light beam may be so located that it passes near the root of the tooth, when the passage of the light beam will cause the motor to stop, or may be so located so that interruption of the beam by the tooth tip has that effect.  In the particular embodiment illustrated, wheel 7 to be treated is mounted on turntable 2 which is driven by motor 3. Hardening burner 19 is mounted on advancing mechanism 13 driven by motor 20 whereby the burner is caused to advance across the tooth. When the arrest signal is emitted by the sensing device 8 driving motor 3 is stopped and motor 20 started. The control circuit may include a counter mechanism upon which the number of teeth is preset, so that when treatment of a wheel is complete the machine is automatically stopped.
Patent GB-630089-A (GB)
Title: Improvements relating to the preparation of powdered metallic oxides into nodules
IPC: C22B1/24
Filed: 1946-12-16
Abstract: Powdered metallic oxide is formed into porous nodules (suitable for direct reduction by hydrogen to metal without fusion, e.g. as described in Specification 630,122) by mixing the finely divided oxide with sufficient water to render the particles cohesive, shaping the moist material into nodules without substantial compression, and drying the moist nodules at a temperature of at least 900 DEG C. but below the softening temperature of the oxide. In the case of iron oxide the drying is effected at a temperature between 900 DEG C. and 1350 DEG C. in an oxidizing atmosphere to ensure that all the iron oxide remains as, or is converted to, ferric ovide.  The oxide may be ground in a ball mill until 5 per cent or less remains on a 270 mesh screen and 75 to 80 per cent passes a 375 mesh screen, and, before shaping into nodules, the moist material may be concentrated in a log washer or magnetic concentrator to remove gangue.  To produce the nodules, the moist material may be extruded through a half-inch to one inch mesh screen which is vibrated horizontally, the nodules being collected immediately from the underside of the screen as they brush off.

Abstract: 340,116. Smith, W. Prince-, and Waterhouse, D. Dec. 7, 1929. Building-motions; doffing-arrangements; thread. holding arrangements.-A spinning &c. machine fitted with a Scaife's building motion and mechanical doffing mechanism is provided with a separable connection, which is rigid and positive during spinning, between the chain rod and rod end iron and with means operable during the doffing operation to control directly the, position and movement of the lifter plates and associated elements. As shown in Figs. 1 and 2, an adjustable stop J on the chain rod G normally engages a pivoted latch H on the rod end iron F and a star wheel N<1> fixed to a ratchet wheel N is journaled on the rod end iron below the latch H. A bracket M on the chain rod G carries a pivoted detent M<2> and a roller M<1> which is adapted to be engaged by the bifurcated end L<2> of a pivoted hand lever L. When doffing, the lever L is depressed until its end L<2> contacts with the roller M<1> when pressure on the lever causes an adjustable stop M<3> on the bracket M to engage the rod end iron F and the detent M<2> to rotate the ratchet and star wheels, the star wheel thus raising and holding the latch H out of contact with the stop J. The weight of the chain rod G &c. is now taken bv the lever L which is allowed to move upwards to lower the lifter rail D and bobbins on to the usual transfer pegs positioned thereunder by an appropriate means such as that described in Specification 220,835, [Class 120 (ii), Spinning, twisting, &c.]. When the empty bobbins have been moved below the spindles, the lever L is again moved downwards to raise the lifter rail to the spinning position, the detent again rotating the star wheel to permit the lever H to fall back in front of the stop J to take the end pressure of the chain rod etc.; the lever L is then raised and retained in the raised position by a pivoted catch P. In the case of a flyer frame the doffing operation may be still further expedited by providing, in the rear of the flyers, the angularly movable prongs &c. described in Specification 339,117.
