Title: A propulsion nozzle of variable outlet area
IPC: F02K1/12
Filed: 1969-12-22
Abstract: 1,244,900. Jet propulsion nozzles - variable area. MOTOREN-UND TURBINEN-UNION MUNCHEN G.m.b.H. Dec.22, 1969 [Dec.21, 1968], No.62452/69. Heading F1J. The invention relates to an aircraft gas turbine jet engine propulsion nozzle of variable area, the nozzle comprising flaps which may be moved inwardly and outwardly of a uniformly tapering end of the engine casing (or aircraft fuselage), the flaps in the extended position constituting an extension of the engine cowling. In Fig. 1 the cowling is shown at 2 and a flap at 3, the flap comprising an inner wall 5 and an outer wall 4, the flap being in the retracted position and the maximum nozzle area being at the plane 3<SP>1</SP>. Between each pair of flaps 3 an actuating member 7 is mounted for longitudinal movement by means of rollers 10, 11 supported by brackets 12, 13 from the cowling 2, the rollers engaging in slots 8, 9 formed in the member 7. The member 7 carries a gear-wheel 16 which engages with a fixed rack 17 mounted within the cowling; the gear-wheel 16 also engages with a rack on a longitudinally movable member 18 which is connected to transmit movement to the adjacent flaps 3. A motor device 35, Fig. 5 is connected through flexible drive shafts 38 and drive units 37 to drive-shafts 39 on which recirculating ball-nut members 41 are mounted, the members 41 being connected to the members 7. Thus as the motor 35 is driven, the member 7 is moved longitudinally and so the member 18 is moved longitudinally at say twice the speed of the member 7. The member 18 carries arms 19, 20 which, have ball members 21, 22 at their ends, the ball members engaging in slots 24, 23 formed in the flaps 3 so that the flaps are moved upon movement of the member 18. The member 7 carries arms 24<SP>1</SP>, 25 on which rollers 26, 27 are mounted, the rollers engaging guide members 27<SP>1</SP>, 28, (29), (30) carried by the flaps 3 whereby the flaps are guided. Further guide-members 33, 34 are carried by the member 7, the forward end portions 32, 31 of the flaps being received in the guides 33, 34; the guides 33, 34 are disposed parallel to the respective guides 27<SP>1</SP>, 28. Sealing members are provided to close off the spaces between the adjacent flaps 3, Figs.6, 7, 8, 9 (not shown). (For Figures see next page)

Title: Fluid level detection system
IPC: G01F23/24
Filed: 1978-08-23
Abstract: The system of the type including a probe having three insulated conducting elements 11, 12, 15 supplied with a periodically varying current 25 and such that a current flows between elements 11, 12 through the liquid when the level reaches element 12, is provided with a fail safe circuit. With liquid at the required level the resistive path through the fluid completes a circuit to conductor 40 whereby transistors 41, 44 are turned on and off during alternate half cycles of the A.C. 25 so that charge built up on capacitor 52 during the half cycle that the transistors are off over conductor 37 is transferred to capacitor 55 during the other half cycles. The charge on capacitor 55 maintains relay 51 energised. If any of the circuits become short- or open-circuited or resistance paths develop between elements 12, 15 and 11, 15 or the level falls below element 12 the transistors remain off and there is no transfer of energy to capacitor 55 and the relay is deenergised. <IMAGE>

Title: Transfer printing
IPC: D06P5/28
Filed: 1979-11-02
Abstract: Transfer printing materials have printed shapes in sublimated inks with adhesive thereover. On a foil of paper or plastics sheet 1 stock shapes 3 are printed the rightway around eg in normal script in sublimated ink with adhesive on the surface 2. These in use are selectively spaced over a carrier paper of foil or plastics sheet, also provided, and transferred thereto in mirror- reversed form by rubbing side 4 with a blunt object. Transferred array of shapes on the carrier is juxtaposed with a final support material and the ink sublimed thereto by pressing with a smoothing iron or passage through the gap of heated rolls, not shown. The carrier may include a coating of a micro-encapsulated material for rendering a textile receptive to the sublimable ink. In a modification laterally symmetrical or non-reversible shapes such as some letters F numerals etcetera having an adhesive, generally contact for instance silicon rubber on their upper surface are transferred directly to translucent material eg. fabric plastics or paper and the material coloured by heating to diffuse the sublimable dye through the adhesive. <IMAGE>

Patent GB-2088307-A (GB)
Title: Marine Propulsion Unit
IPC: B63H11/04
Filed: 1980-10-09
Abstract: This invention relates to prime movers in which relatively high speed liquid is directed through a narrow slot which is submerged in relatively low speed or stationary liquid. On one side of the slot exit a convex surface leads away generally at right angles to the direction of the high speed flow through the slot. The interaction between the high speed and low speed liquids produces a unidirectional force generally at right angles to the angle of the slot, which force may then be used to move the carrier of the slot and convex surface through the low speed or stationary liquid. <IMAGE>
