Abstract: 1,103,020. Jet propulsion nozzles. ROLLSROYCE Ltd. Dec. 23, 1966, No. 57805/66. Heading F1J. A jet engine comprises a propulsion nozzle which has an upstream portion provided with a variable area outlet, means for varying the variable area outlet, and a downstream portion having a fixed area outlet, the downstream portion being rigidly connected to the varying means and being adapted to move axially therewith relative to the upstream portion. A plurality of pivotable flap members is positioned axially between the varying means and the downstream nozzle portion, and radially outwardly of the upstream nozzle portion, the flaps being arranged either to allow or to prevent flow of ambient air to the inner surface of the downstream nozzle portion. In the embodiment shown, a series of flap members 23 are pivotally mounted at the downstream end of the jet pipe 18 and the positions of the flaps are controlled by means of a series of rollers 31 which are rotatably mounted on a frusto-conical ring member 25 which is movable axially by actuators 32. The ring member is connected by means of circumferentially-spaced struts 26 to a downstream nozzle portion 24, and a series of flap members 28 are pivotally mounted on the frusto-conical ring in the spaces between the ring, the nozzle portion 24 and the struts 26. The flap members 28 are urged by resilient means to the outer, closed position. When the ring member 25 is in its forward position the flap members 23 are in the minimum area position and the boundary of the gas stream is as indicated by the broken line 36 so that a region of low-pressure is created in the space 38. Ambient pressure acting on the outer surfaces of the flaps 28 causes the flaps to open inwardly so that the pressure within the space 38 is increased thus reducing the "base drag".

Abstract: 1381305 Mixing flowing fluids A R SCHLOSSHAVER 16 Dec 1971 [16 Dec 1970] 58533/71 Heading B1C [Also in Divisions F2 and G3] In a device for spraying a lubricant into a flow of compressed air, to which the lubricant is supplied in intermittent pressure pulsations and. the air continuously, lubricant enters at S and flows through chamber 16, and passages 6, 7. The oil pressure acting on face 19 of piston 10 lifts valve body 15 off its seat 14 and permits compressed air from inlet L to flow from passage 3 to chamber 24, passage 13, chamber 11, passage 34 and chamber 32 to the nozzle head D. Air pressure in chamber 11 acting on piston 12 causes the annular groove 23 to register with passage 7 admitting lubricant to chamber 9 and nozzle head D. Thus each component of the mixture must be present before the other is admitted to the nozzle head. The value member 8 also actuates through a member 26 a switch 31 the signal from which is fed to an alarm which becomes active if the signal is present or absent for a preselected time, i.e. if supply of either of the mixture components fails. Alternating the switch may actuate means to stop the machine to which the lubricant mist is supplied.. Should the nozzle head D become blocked, the increased lubricant pressure in chamber 16 will cause the face 19 of piston 10 to uncover passage 5 whereby the lubricant is returned to a container 2.

Abstract: 680,992. Actuation of switches. NATIONAL CASH REGISTER CO. June 22, 1948 [Dec. 6, 1947], No. 16705/48. Class 38 (v) [Also in Groups XVI, XIX and XXIV] The driving motor of a combined calculating and typewriting machine is switched on by a finger lever and is switched off after a given "running period", i.e. after a certain number of revolutions if the calculating or typewriting mechanisms are not operated. The counting of the number of revolutions is started anew each time the calculating or typing mechanisms are operated. When the finger lever 222, Fig. 9, is turned to the "on" position a rod 375 is pulled down to rock clockwise an operating lever 376 to rock a toggle member 379 which operates the switch 221. The operating lever is held in both positions by a roller 382 on a spring-urged arm 383. The motor controlled by the switch drives a gear 311 which oscillates a lever 405 carrying a pawl 410 having a long tooth 422 and a short tooth 423. The long tooth 422 drives at each oscillation the lower 403 of a pair of ratchet wheels 403, 404, Fig. 10. Once in each rotation of the lower wheel 403 the long tooth 422 falls into a deep notch 424 in the lower wheel and enables the shorter tooth 423 to engage and drive the upper ratchet wheel 404 one step. The switchoperating lever, by a pin-and-slot connection 391, rocks counterclockwise an arm 392 to which is pivoted a pawl 394 urged clockwise by a spring 395, the upper part 426 of the pawl then coming into the path of a pin 425 on the upper ratchet wheel 404. The pawl 394 is thus rocked counterclockwise by the pin 425 and is retained by a latch 398 urged by a spring 400. As the upper ratchet wheel 404 continues to rotate, the pin 425 meets the now-raised end 397 of the pawl 394 and rocks the arm 392 and lever 376 to open the switch. In order to start the running period anew each time the calculating or typing mechanism is operated, the latch 398 is tripped at each such operation, by means not shown in Fig. 9, to release the pawl 394 should this be in its counterclockwiserocked position. Specifications 448,791 and 509,042, [both in Group XIX], are referred to.
