Abstract: 1,179,204. Gas turbine ducted fan engines. ROLLS-ROYCE Ltd. Sept.27, 1968, No.46076/68. Heading F1J. A gas turbine ducted fan engine comprises a gas generator for supplying gases to a flow duct in which is mounted a free turbine, the free turbine carrying a fan for rotation therewith, the fan being located entirely within the axial extent of the gas generator in a flow duct surrounding the first flow duct, the gas generator being in the form of a gas turbine by-pass type jet engine and comprising a two-stage LP compressor 15, a threestage HP compressor 16, combustion equipment 17, a single stage HP turbine 18 and a two-stage LP turbine 19. The HP turbine drives the HP compressor through shaft 21 and the LP turbine drives the LP compressor through shaft 20. A portion of air delivered by the LP compressor passes to by-pass duct 23 which extends into a flow duct 27. The gases discharging from the turbine 19 are diverted through a 180 degrees bend and flow axially forwardly through duct 25 and then outwardly into the flow duct 27 where the gases and bypass air are mixed. A two-stage free turbine 13 is disposed in the duct 27 and is driven by the gas and air mixture flowing therethrough. A fan 30 is mounted radially outwardly of the second stage free turbine blades 32, the fan being located in a duct 34 formed between inner wall 28 and outer wall 29. Outlet guides vanes 35 are disposed downstream of the free turbine and outlet guide vanes 36 are disposed downstream of the fan 30. The fan drive turbine 13 is supported on bearings 42 from stator structure 40. The turbine 13 may be formed of fibre-reinforced plastics material since the working fluid is relatively cool. Working fluid may be tapped from the duct 27 through opening 41 for cooling purposes, for example for flow through the outlet guide vanes 35. The engine is of short axial length and may be mounted in an aircraft with its axis vertical so as to provide vertical lift.

Each hearth 24 incorporates three burners 28, 30, 32, upper and lower flues 40, 42, and ducts 43 for cooling or introducing an artificial atmosphere. Material introduced into the top sub-housing 21 through a hopper 22 passes beneath an adjustable gate 54 on to the first hearth 24 whence it travels down over each hearth in turn, aided by the push plates and also agitated thereby. In another embodiment (Fig. 3) the housing (100) is straight sided, to aid sealing for partial vucuum heating. In a further embodiment (Fig. 2) the hearths are parallelly inclined and can be adjusted in inclination by a supporting column and associated power screw. The angle of inclination is related to the angle of repose of the material in the furnace.

Abstract: 1,115,826. Orientating diode seals. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 18 Oct., 1966, No. 46449/66. Heading B8S. Seals 10 to be oriented are fed by an operator by means of magnet 15 from tray 13, the seals being transferred thereby to the compartments of holder 16. Rack 31 is then positioned over the open top of the holder 16 by the said operator so that they form a unit, and the unit is then inverted and held down by handles 23,24 so that its legs rest on a vibrator. This causes the seals in holder 16 to be jogged so that they fall down into the holes 33 of the rack and rest there with their upper parts 12 resting in the holes as shown. The seals are thus orientated ready for the next process.

Abstract: 1,055,392. Electric selective signalling. ENGLISH ELECTRIC-LEO COMPUTERS Ltd. Nov. 26, 1964 [Nov. 26, 1963], No. 46640/63. Heading G4H. In a system for checking the correct functioning of a line printer each hammer and associated core in a matrix store is associated with a flipflop 5 which is set by a signal representing data present in the core on a line 12 and subsequently triggered by a signal on line 9 representing operation of the hammer and correct operation of all the printers on a line generates a signal on line 15 through an AND gate 14 to line-feed the paper. Non-actuation of a hammer prevents the bi-stable circuit 5 triggering to its re-set state and one of the inputs is removed from the AND gate to prevent the signal on line 15. A timing device 16 set at the beginning of each printing cycle generates a signal on line 18, if not inhibited from line 15, indicating non- operation of a hammer although permitting a prescribed number of further lines to be printed, e.g. to the end of the page. A further flip-flop 24 is set by line 28 as each character position in the core matrix is read and is re-set by a pulse from a pulse circuit 19 and OR gate 20 operated by the setting of flip-flop 5 by a data read signal on line 12. If the signal on line 12 is not generated, flip-flop 24 is not re-set and an error signal from an AND gate 25 is generated providing a signal on line 26 is present corresponding to the data in the core representing a character. If a sense amplifier generating a signal on line 13 when the character in the core corresponds to the type to be printed operates a second time after the hammer trigger 9 has operated a pulse is again generated by circuit 19 to give an error signal on line 23 in combination with a print signal on line 22. The printer comprises a line of hammers corresponding with lines of type on a rotating cylinder wherein all similar letters are printed simultaneously.

Abstract: 1,210,273. Photo-electric measurement of optical circular dichroism. DURRUM INSTRUMENT CORP. Oct. 2, 1968 [Oct. 30, 1967], No.46695/68. Heading G1A. The differential absorption of right and left circularly polarized light by a dichroic sample is measured by passing a beam of light through the material which light periodically alternates from being right to left circularly polarized, varying an optical element in the light path so as to occlude more or less of the right or of the left circularly polarized light so as to obtain equal transmission by the sample and then indicating the position of the optical element as representative of the difference in absorption. In one arrangement, Fig. 1, light from a monochromator 11 is collimated at 13 and split into ordinary and extraordinary rays by Rochon prism 16. Only the ordinary ray is used and this is passed through a second Rochon prism 21 to a Pockels cell 24. This is energized at a frequency f to change the plane polarized beam 22 into first right and then left circularly polarized light which is passed through the sample 27 where it undergoes absorption in accordance with the circular dichroism of the sample. A photo-multiplier 29 produces a signal having a D.C. and, if the sample exhibits circular dichroism, an A.C. component, the latter being directed by circuit 32, 33 through A. C. amplifier 34 to a synchronous detector 36 which also receives the reference signal f. Any phase difference, representative of differential absorption due to circular dichroism, is transmitted as a D. C. signal via amplifier 42 and A. C. filter 39, to alter the rotational setting of Rochon prism 16, which is also oscillated at frequency f so as to provide an A. C. variation in the detector output. The position of rotation of prism 16 is indicated. The prism 16 should have no rotary power or an additional polarizer is required. In another arrangement, Fig. 3 (not shown), this prism (16a) may exhibit rotation, since instead of using the detector signal to move this prism, a nulling element in the form of a rotatable sectored neutral density filter (which is also oscillated at frequency f) is used.
