Title: Improved jet noise suppressor nozzle
Inventor: BROWN DAVID MORRIS
IPC: F02K1/48
Filed: 1957-09-02
Abstract: 838,617. Jet-propulsion nozzles. ROLLSROYCE Ltd. Aug. 12, 1958 [Sept. 2, 1957], No. 27685/57. Class 110 (3). A jet noise suppressor nozzle comprises a plurality of longitudinally extending, substantially radial hollow lobes through which the hot jet gases flow, the lobes being angularly spaced from each other in a circular arrangement and increasing in radial extent in the downstream direction and having substantially radially extending walls which are corrugated at least in part substantially longitudinally. The nozzle 10, Fig. 1, comprises a plurality of longitudinally extending substantially radial, hollow lobes 8 through which the hot gases flow in the direction of the arrow 9. Each lobe 8 increases in radial extent in a downstream direction and increases in cross-sectional width radially outwards. The radial walls 8<1>, 8<11> are formed from an internal skin 12, Fig. 3, which forms the gas passage and an external skin 11. The two radial walls of the skin 12 are corrugated symmetrically at 14. The corrugations which extend longitudinally of the nozzle but do reach its downstream edge, form in transverse section, a bubbular configuration. The hoop stress in each bubble is taken by longitudinal stiffeners 16 joined by discrete transverse local ties or struts 13 of aerofoil section. The skins 11 and 12 are braced by struts 15 attached to the stiffeners 16. Additional longitudinal stiffeners may be attached to the internal skin of each lobe 8. In a modification, Fig. 6 (not shown), a lobulated frame is located internally of the downstream end of the nozzle, the lobes of which are attached to the lobes 8 to brace them. In this arrangement, the members 13 are replaced by continuous I- shaped members. Each lobe 8 may have a throat to form a convergent - divergent nozzle.

Title: Improved process and apparatus for reversing and opening folded sheets for the purpose of stitching same
IPC: B42B2/00
Filed: 1936-10-13
Abstract: 464,620. Machines for stitching or stapling book-signatures. LUTOLF, O. Oct. 13, 1936, No. 27758. [Classes 89 (iii) and 112] A machine for stitching or stapling book signatures is provided with means for reversing and opening the sheets supplied by a folding machine. The invention is illustrated as applied to a stitching machine. A shaft 5 is rotated by a belt pulley 3 from a motor 2 carried on the frame 1 of the stitching machine. The motion is transmitted by a chain drive 6, 7 to a shaft 8 with a toothed wheel 9 driving toothed wheels 10, 11 on a pair of rollers 13 carried in the frame 12 of a sheet-reversing device. Pairs of conveyer bands 14 run in grooves over these rollers in a direction contrary to that of the rollers 13. Sheets coming out of the folding machine between the last pair'of guide rollers 15, see arrow d, Fig. 3, are conveyed towards the rollers 13 between the inner parts of the conveyer bands 14 carried by the rollers 16 and guided and tensioned by rollers 17, 18, 19, 20 and 21. The sheets are thrown upwards by the rollers 13 towards the apex of a sheet-opener 22. On its passage between the rollers 13, the sheet presses against a flap 23 of a locking device for actuating a release mechanism 25 of a coupling 26. When the coupling 26 is released, the sheet opener, sheet-feed and stitching mechanism can operate. The sheet opener consists of two wings 59, Fig. 4, with a scissors-like movement about a common pivot 58. It is actuated when the coupling 26 causes a pawl 56 to engage the ratchet wheel 57 to drive the shaft 49, Fig. 15. The shaft 49 transmits its motions to a shaft 65 through bevel gears to cause an arm 64 to operate a link 66 to operate strips 73 co-operating with the members 59. The sheet is then punctured and dropped on to the stitching saddle 114 where it is held by a spring-pressed roller 100. The sheet is forced by a stop 102 on the angle-shaped feed member 48 under the reverser 104 of the stitching head 106, stitched and thrown off by the forward feed member 48a into a collector.

Abstract: 796,295. Gas-holders. NORTH WESTERN GAS BOARD. Aug. 27, 1956 [Sept. 30, 1955], No. 27843/55. Class 54. Means for maintaining a minimum pressure in a gas-holder when it is only partly inflated comprises a water chamber 2 in the uppermost lift 1, means for pumping water into the chamber while a lower lift is descending, and means for withdrawing the water from the chamber as one of the lifts is ascending. Water is pumped from a tank 3 through a flexible pipe 5 to the chamber 2, which is in the form of an annular tank constituting a component part of the top curb of the lift 1, by one or more pumps 4 adapted to be started as a second lift 10 approaches its bottom position, a striker 9 on the lift 10 then actuating a limit switch 8 to start the pump. When sufficient water to provide the necessary additional weight to maintain minimum pressure has been delivered to the tank 2, a ball valve 6 closes and the pressure in the pipe 5 may actuate a relay switch to stop the pump. During inflation of the holder, a striker 12 attached to the lowermost lift 11 actuates a switch 13 which restarts the pump 4 to raise the level of the water sufficiently either to bring one or more siphons 14 into operation or to reverse the direction of the pump to discharge all the water from the tank 2 into the tank 3; the period of operation of the pump may be set by a time switch.

Abstract: 1,078,195. Running generators in parallel. KHARKOVSKY ELEKTROMEKHANICHESKY ZAVOD. Jan. 15, 1964, No. 27892/63. Heading H2H. An arrangement for equalizing the load on D.C. machines operating in parallel, such as D.C. generators or motors comprises connecting the field windings of the machines in two groups, one of which groups is connected in series with the armature of the same machine whilst the other group is connected with the armature of the other machine. The auxiliary field windings 1 and the compensating windings 2 are each divided into two parts and serially connected together. A differential compound winding 6 is connected in series with one pair of part windings 1, 2 to form a group 1, 2, 6 and a compound winding 5 connected in series with the other pair of part windings 1, 2 to form a second group 1, 2, 6. In the case of parallel operating generators the group 1, 2, 6 of each generator is connected to its associated armature 3 or 4 whilst the group 1, 2, 5 is connected to the other armature 4 or 3. In the case of parallel operating motors the reverse is the case with the group 1, 2, 5 of each motor being connected to its associated armature whilst the group 1, 2, 6 is connected to the other armature. Thus the cross-section of the connections between the coils is reduced and the number of terminals on the machines is also reduced.

Sept. 25, 1930, No. 28724. [Class 79 (iii).] A power transmission system of the kind in which a prime mover, e.g. an internal-combustion engine, drives an electric generator to supply power to motors driving the road or track wheels, is provided with an auxiliary motor independently supplied with power and adapted to drive the generator. Thus, in tunnels or in dense traffic when it is desired not to use the internal-combustion engine the generator may be driven by the auxiliary motor, and the engine and the auxiliary motor may be used together when extra power is necessary. The auxiliary motor may be supplied with power from an external conductor or from a battery carried on the vehicle; in the former case the supply may be single phase at high voltage. The prime mover and the auxiliary motor may be permanently coupled to the generator, or clutch mechanism may be used to disconnect either at will. Where power is supplied to the auxiliary motor through an external conductor the supply may be controlled by a switch so connected to the engine controlling mechanism that the switch cannot be closed unless the engine fuel supply has been cut off, and, conversely, fuel cannot be supplied to the engine until the switch has been opened.

Abstract: 1391663 Fluid control system MESSERSCHMITT-BOLKOW-BLOHM GmbH 21 June 1972 [24 June 1971] 29037/72 Heading F1P A differential piston 8, Fig.2, is controlled by a pair of valves each of which comprises a freely movable circular foil 12, 19 enclosed in housings 5, 16 respectively. If an electromagnet 34 is energized, a lever 32 is rocked to close an inlet 13. This causes the foils 12, 19 to move to the positions shown in which fluid passes through conduits 2, 6 and moves the piston 8 to the right until it abuts a stop 35. A throttle 37 causes the foil 19 to be held in the position shown by back-pressure. If magnet 33 is energized, inlet 13 will be opened and foil 12 will move upwards. This allows fluid to flow through conduits 2, 14, 17 to move the piston 8 to the left until it abuts a stop 36. In the embodiment shown in Fig.3 a stable position of the piston between stops 35, 36 can be obtained. Outlets 13, 20 are closeable by spring-loaded pistons 43, 44, when the latter are fully depressed by magnets 47, 48. To move the piston 8 to the right electromagnet 48 is de-energized causing the foil 19 to move upwards. The foil is held in this position by leakage fluid which passes through a conduit 49. This opens the exhaust passages 17, 15, 21  and the piston moves to the right until the magnet 48 is again energized. To move the piston to the left, magnet 47 is de-energized, thus allowing the foil 12 to move to its upper position thereby supplying pressure fluid through conduits 2, 4, 14, 17 to the right hand side of the piston.
