Title: Improvements in or relating to bearing arrangements for gas turbine engines
IPC: F16C37/00
Filed: 1969-11-04
Abstract: 1291466 Turbine bearing arrangement BENNES MARREL 4 Nov 1969 [28 Nov 1968] 53978/69 Heading FIT The invention relates to a bearing arrangement for the power shaft of a gas turbine engine. The engine shown comprises a compressor-drive turbine 3, and a separate power turbine 7 mounted on a shaft 9, the exhaust gases from the turbine 7 passing through duct 8. A bearing support member 11 is secured to the turbine casing structure and is thermally insulated from the exhaust duct 8 by a layer of insulation 13. A bearing support 12 is located within the support member 11 with provision for axial sliding movement therein, the support 12 carrying a bearing 23 in which the shaft 9 is rotatably mounted with freedom for axial movement. Three bolt members 33 extend through the support 12 to engage a ring member 35, seal members 36 and key members 37 being secured between the ring 35 and the support 12. The key members 37 project radially outwardly and are received in keyways 38 formed at the forward end of the support member 11 whereby the bearing support 12 is located circumferentially. The support 12 is secured to a rear block 21 by four through-bolts 22, Fig. 4 (not shown), the block 21 being located within the support member 11. The block 21 carries a bearing (25) which is disposed between radial portions (26), (27) of the shaft 9 whereby the shaft is located axially. The bearing (25) is located between members (28), (29) secured to the block 21. The bearings 23, (25) are supplied with lubricant through duct (47) and bores (50), (48). Cooling air flows between the insulation layer 13 and a casing 16 as indicated by arrows 15, the air discharging into the exhaust duct 8 through openings 17. Ambient air is drawn in through inlets 19 and flows between the casing 16 and the support member 11 as indicated by arrows 44, Fig. 1 the air passing through bores (43) finally passing to the bearing 23; the air is drawn in by the screw pump 41, 42 formed by a screw thread on the shaft 9.

Abstract: 1,137,820. Anchoring device. H. J. MODREY. 5 Dec., 1967, No. 55356/67. Heading F2H. A wall anchor for anchoring in a mounting hole in a wall or other support member comprises a hollow internally screw - threaded shank 1 having at least two resilient arms 2, 3 extending outwardly from a peripheral edge of said shank at an acute angle to the centre axis of the shank, each leg having at its tip a first hook 4 within the general plane of the leg and a second hook 5 extending transversely to the centre axis of the shank providing a surface facing but spaced from said first hook, and a screw 8 screwable into said shank. Each leg is provided with a score line 7 to facilitate bending, the legs being formed of a strip of springy metal. The wall anchor described may be used as an expansion bolt in a blind hole in which the hooks engage the walls of the hole. Alternatively it may be used as a hollow wall anchor, the hooks engaging in the rear of the wall and tightening of the screw causing bending of the legs. As a further alternative the device may be used as a blind nut with the first hook 4 engaging inside the hole and the second hook 5 engaging the rear face of the wall so that tightening of the screw causes bending of the legs and the hook 4 is brought into engagement with the screw.

Sheets present in the bins are detected by the interruption of light beams from sources 306, 307 to detectors 303, 305. At the start of a sorting operation, if only one bin is empty, sheets are directed to that bin, if both are empty to the bin 55, and if neither are empty the operation is precluded. In each bin, sheets are directed to successive trays by deflectors 76, 123 actuated by individual solenoids, the arrangement being that when a sheet is detected, by a photo-electric device 80 or 127, entering a tray, the deflector for the next tray is set. The sorter can be programmed to act as a collator, a copy being made from each original and the copies being fed to successive trays, and then a further copy being made from each re-circulated original, and so on, so that each tray will finally contain one copy of each original, or to act as a stacker, several copies of one original being made and all fed to one tray, the deflectors being actuated when a desired number of copies have been counted, so that all copies of the next original are passed to the next tray and each tray finally contains a plurality of copies of one original.

Abstract: 1,175,194. Dynamic compressors. BROWN, BOVERI & CO. Ltd. Dec.20, 1966 [Dec. 22, 1965], No.56950/66. Heading F1C. [Also in Division G3] A controller with separate means for applying proportional feedback and reset to a controlling member; and used to prevent surging in compressors, has a connection between the reset means and the controller output providing a fixed impedance to flow and a connection between the feedback means and the output providing a higher impedance to flow in one direction than in the other whereby the feedback time-constant when regulating in one direction is reduced to a fraction of the feedback time-constant when regulating in the other direction. The quantity to be regulated is applied to a spring-loaded bellows 4 actuating a nozzle and flapper valve 8 through a beam 15. Compressed air is supplied to the valve from a line 3 via a throttle 10 and the pressure upstream of the valve is amplified at 11 to provide an output pressure in a line 2. To provide the difference in time-constant, air enters a feedback bellows 7 via throttle 13 during periods of increasing output pressure but escapes rapidly through a non-return valve 14 when the output pressure falls, the controller being reset by a further bellows 6 and throttle 12. If the quantity to be regulated varies sinusoidally, the output falls in a sawtooth-like curve and may be used to operate a blow-off valve on the compressor. A variable resistor and rectifier may replace the throttle 13 and valve 14 if electrical control is required.

A coupling for joining the ends of pipes 10, 11 comprises clamping means consisting of rigid, complementary generally semicircular members 18, 19 having radial lugs 21, and an axially and circumferentially continuous circular gasket 27 interposed between the clamping means and the pipe ends and spanning the pipes. The gasket has diametrically opposed, outwardly extending, axially elongated integral ears 50 clamped between the lugs 21, the latter being urged toward each other by means such as screws 24, whereby the ears are compressed between the lugs; the ears are concavely curved and thickened at the inner edges thereof and the lugs have complementary curved portions whereby compression of the ears exerts a radially inward force on the gasket to accommodate for dimensional variations in the pipe ends and clamping means, the outer edges of the ears being clamped between the lugs radially outwardly of the complementary curved portions of the lugs whereby the lugs are spaced apart by the ears. The gasket may include internal annular ribs 30 ... 33 for forming a seal against the pipes, an external, annular rib or ribs 37, 39 and 40 which is or are accommodated within an annular recess 22 formed in the clamping means, and a central, internal annular rib 29 which is disposed between the adjacent ends of the pipes.
