Abstract: 1,258,331. Gas turbine ducted fan engines. GENERAL ELECTRIC CO. March 28, 1969 [March 28, 1968], No. 16294/69. Heading F1J. The invention relates to gas turbine ducted fan engines and particularly to means for mixing the turbine exhaust gas flow and the fan air-flow. The engine shown comprises a gas turbine gas generator 12, and a separate turbine 14 connected through shaft 15 to drive the fan 16 air delivered by the fan passing in part to the compressor 24 and in part through the annular duct 22, the turbine exhaust gases and the fan air passing through a mixing device 30 before discharging through propulsion nozzle 32. The turbine exhaust gases pass through a series of chutes 34 and the fan air from annular duct 22 passes through the spaces 36 between adjacent chutes. Each chute 34 is defined by a pair of side walls 42, 44, an inner wall 38 and an outer wall 40, the wall 40 diverging from the wall 38 in the direction of gas flow and the walls, 42, 44 which are substantially radial, converging in the direction of gas flow, the resulting sections at lines III, IIIA, IIIB, IIIC in Fig. 2 being as shown in Fig. 3 and the sections at lines IV, V, VI, VII being as in Figs.4, 5, 6, and 7 (only Fig. 6 is shown), the sections being of teardrop shape. The downstream portion of each wall 44 is defined by a pivotally mounted flap 48 whereby the area of the gas flow chute may be varied. Each flap 48 is operated by a link 52 and an axially-movable unison ring 54 which is movable by an actuator 56. A series of ports 60 are provided in the outer wall 101 of the gas flow duct between the turbines 28, 14 each port being controlled by a valve 62 operated by a piston device 68 such that when the valves are open a portion of gases pass through ports 60 into the annular fan air duct 22 whereby the fan turbine 14 supplies less power and the fan less air therefore. The ports 60 are located in line with the fan air spaces 36 between the chutes 34, Fig. 3. The radial walls 42, 44 of the chutes are utilized to transfer loading from the bearing 93 and structure 95 to a support ring 97 and turbine casing 99. A thrust reverse device comprising movable flap members 102 and blade cascades 100 is provided whereby the fan air may be discharged with a forward component for aircraft braking. A portion of fan air flows in the spaces between the outer walls 40 so as to provide cool air in this region.

A blue-sensitive (this term means that direct positive compositions will provide a reversal image when exposed with radiation in the 350-500 millimicron wavelength range of the spectrum) photographic direct-positive silver halide emulsion in which the silver halide is at least 50 mole percent silver chloride contains an organic electron acceptor and a BSI (Blue Speed Increasing) compound (i.e. a compound which has an anodic polarographic half-wave potential which is less than 0À85 and a cathodic polarographic half-wave potential which is more negative than -1À0 and which when incorporated into a specified fogged silver chloride emulsion defined in British Patent no 1,186,718 gives an increase in speed). The BSI compound may be a merocyanine dye, examples of which are given. The emulsion may in addition contain a compound containing a polynuclear aromatic group (i.e. a group containing two or more benzene rings fused together or at least two benzene rings or other aromatic carbocyclic nuclei directly joined together or joined through an aliphatic linkage) and a sulpho group of the formula -SO 3 M, wherein M is H or a cation which will render the compound water soluble, which is carried as a substituent on an aryl group which is connected to or forms part of the polynuclear aromatic group. The electron acceptor preferably has an anodic polarographic half-wave potential and a cathodic polarographic half-wave potential (measured as described in the Specification) which when added together give a positive sum. The electron acceptor may be a cyanine dye preferably containing an imidazoquinoxaline nucleus. Many examples of electron acceptors are listed. The exposed material containing an emulsion as defined above may be developed using a developer solution containing a polyhydroxybenzene developing agent which may be hydroquinone. The developer solution may be capable of infectious development. Improved photographic properties can be obtained with the present direct-positive emulsions, e.g., the background density of the emulsion is particularly low.

Abstract: 1,265,206. Evaporators, film type; treatment of coffee extract. PROCTER & GAMBLE CO. 18 July, 1969 [19 July, 1968], No. 36272/ 69. Heading BIB. [Also in Division A2] Volatile flavours are removed from aqueous coffee extract by forming the extract into a film in an evaporation zone maintained at an absolute pressure of 6-15" Hg, supplying heat to the film to maintain it at boiling point, maintaining the film in the zone for 5-30 seconds to evaporate therefrom volatile flavours and 5-30% by weight of its water content and recovering the evaporated flavour laden water fraction. In a process of making coffee powder, roasted ground coffee is steam distilled to give a flavour-laden distillate and then extracted to give an extract containing 10-40% by weight coffee solids. The extract is then subjected to the above mentioned flavour stripping process to form an aqueous coffee concentrate and an evaporated flavourladen water fraction which is condensed: The aqueous coffee concentrate is subjected to a film evaporation process comprising one or more evaporating steps, to remove 40-90% by weight water therefrom. In the latter evaporating step(s) the absolute pressure is maintained at 0.5-15" Hg and the temperature is 60-180‹F. The resultant concentrated extract is mixed with the flavour-laden distillate and the flavour-laden water fraction and the mixture is dried e.g. by spray-drying, freeze-drying or foam drying. The coffee powder may be subjected to the processes described in U.K. Specification No. 1,165,656 and Specification 1,265,205. The film evaporators may be falling film or rising-falling film evaporators in which the extract is moved through evaporating tubes mounted in a shell through which heat exchange fluid is passed.

Abstract: 1307234 Tool for removing annular members, e,g. from shafts T H MILBOURN 22 July 1970 [24 July 1969] 37210/69 Heading B4C A tool for removing an annular member from a secured position, e.g. from a shaft, comprises a plurality of substantially parallel rods 1, each having a hook 1a at one end and a portion 1b at the other end engageable by a pin 4b carried by a member 4. Each rod is mounted in member 2 for rotation about its axis by appropriate rotary movement of the member 4 relative to the member 2 so that the hooks 1a can be moved from the orientation of Fig. 2 to extend radially inwardly or radially outwardly in order to engage behind an annular member. Subsequent movement of the rods in direction A effects removal of the annular member from its secured position. When removing a member from a shaft a screw-threaded bolt 5 received within a bore in the member 2 engages one end of the shaft. In use the tool is adjusted until the hooked ends of the rods extend over the annular member on the shaft. Rotation of the member 4 then causes the rods to rotate about their respective axes so that the hooks 1a are positioned behind the annular member. The bolt 5 is then rotated so as to move the annular member towards the end of the shaft. To facilitate use the parts 4c and 2b may be of hexagonal section. Member 3 is rigidly secured to the member 2 or may be integral therewith.

Abstract: 1310664 Data processing INTERNATIONAL BUSINESS MACHINES CORP 28 Jan 1971 3346/71 Heading G4A [Also in Division H4] A digital electric data handling system comprises a plurality of functional units (FUs) joined by a common bus BS, there being error detecting means E and unit isolating means A, I, G associated with each FU so that, if an FU is erroneous, all the non-erroneous FUs are disconnected from the bus so that the erroneous FU can be diagnosed. Each error detecting means E is connected to an error indicator L which, when set, enables AND gates A, the other respective inputs of which are connected through invertors I to means E. When an AND gate is activated a gate G disconnects the FU from the bus. A diagnostic unit DU is enabled by indicator L and operates on the erroneous FU or FUs connected to the bus BS. A bus CS enables all or some of the units to be disconnected or connected for other reasons by triggering indicator L and the invertors I. In another embodiment (Fig. 2, not shown) the FUs are memory units as described in British Specification 1,127,270, each FU comprising two identical halves which operate on the same data and issue an error signal when a comparator indicates disagreement. Gating circuitry then isolates units by stopping their clocks (Fig. 3, not shown). If more than one FU at a time has an error only one FU will be connected for diagnosis at a time due to a priority system. As with the system of Fig. 1 FUs can be connected or disconnected for other purposes. A failed FU can be replaced by a spare FU. In another embodiment (Figs. 4 and 5, not shown) a number of systems as in Fig. 2 can be combined using an interface and can have a common diagnostic unit, console &c. and an inter system priority arrangement. A telephone line and a printer are also mentioned.
