Patent GB-1301615-A (GB)
IPC: F02C9/16
Filed: 1971-04-20
Abstract: 1301615 Gas turbine by-pass engines: axialflow compressors; starting SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 20 April 1971 [23 April 1970] 10153/71 Headings F1C F1G and F1J Device to facilitate starting a turbojet engine having an axial-flow fan which produces a stream of compressed air which is split into coaxial inner and outer streams, comprises a ring of inwardly-projecting blades upstream of the fan and having a radial height not greater than that of the outer flow, the blades being rotatable about axes radial to the axis of the engine so that their trailing edges move in the direction of rotation of the fan, and means for supplying compressed gas to passages formed in the blades and opening at their trailing edges through bleed orifices. The engine comprises a low-pressure compressor fan 4 having a series of blades 3, which provide a stream of compressed air, part of which passes to a high-pressure compressor 6 and the remainder of which flows through an annular duct 8. In front of the first set of blades 3a of the fan 4 is a ring of blades 12, each blade being symmetrical about a plane 15, and being pivotable about an axis passing through that plane. To reduce the power required from the starter motor, the blades are moved to the position shown in Fig.2 and air is blown through holes in the trailing edge of each blade, so that it impinges on the blades 3a of the fan. During normal running the blades are maintained parallel to the axis of the engine, as shown in dotted lines in Fig.7. To limit wind milling of the engine after a shutdown in flight, the blades can be turned to the position shown in chain-dotted lines in Fig.7. The blades can also be turned to a position to reduce fan noise when the aircraft is on the approach. The blades are rotated by levers 23 fixed to the blade spindle 18 and pivotally connected to a ring 24, which is rotatably mounted on the fixed part of the engine carrying the spindles 18. The ring is rotated by two diametrally opposite jacks, each consisting of a bracket 29, Fig.6, connected by a link 28 to a toothed sector 30 which is rotatable about a centre 30a. The sector teeth engage a screw 31, driven through worm gearing by a motor 33. The screw 31 also carries a pinion 42 Fig.8, which meshes with a rack 41 to open a valve 37, which allows compressed air from an inlet 35, to pass to an outlet 36 and hence to an annular chamber 20, Fig.1. Air from the chamber 21 passes through the spindles 18 to the interior of the blades. In a modification, the ring 24 is rotated by fluid-operated double-acting reciprocating motors connected to the ring through a bell-crank mechanism.

Title: Gas powered drive unit
IPC: A61B17/00
Filed: 1971-04-20
Abstract: 1344837 Pneumatic actuators UNITED STATES SURGICAL CORP 20 April 1971 [28 April 1970] 10239/71 Heading F1D [Also in Division A5] A pneumatic actuator 10 for operating a surgical skin stapling instrument comprises a piston 16 with an integral output shaft for actuating the stapler, the piston 16 being reciprocable in a casing member 20, and a spool 28 for controlling reciprocation of piston 16, the spool 28 being movable over a short distance in a plug 22 and having a seal 46 which normally closes gas inlet 46 under the bias of spring 30 urging the piston and spool rightwards, Fig.1. Spool 28 and piston 16 have O-rings 58, 62, 72 housed in annular seats 60, 64, 74, the depth of the seats being greater than the O-ring diameters. Communicating with seats 60, 64, 74 are bores 56, 66, 76 which, during piston reciprocation, transmit gas pressure to the inner side of O-rings 58,  62, 72 to urge them into tight sealing contact with plug 22 and casing member 20. In operation, a triggering means Fig.3 (not shown) moves shaft 14 in the direction 116 thus permitting gas pressure in inlet 42 to act on seal 46 to urge the spool 28 leftwards. Gas thus passes through bore 56, communicating with seat 60, and then through a restriction and threaded bore 48 to the right side of piston 16 which is thus moved to the left. Gas is fed to bores 66, 76 which communicate with seats 64, 74. The end of the movement to the left of piston 16 is damped by progressive throttling through co-operating chambers 82, 84 on the piston 16 and member 20. The return stroke is effected by spring 30 which causes piston 16 to thrust gas through a by-pass 68 in spool 28 to an annular chamber 70 communicating with an exhaust port 90.

IPC: D04B35/10
Filed: 1919-04-30
Abstract: 137,979. Spiers, W. April 30, 1919. Circular machines, particularly multi-feed types, are provided with yarn-controlled devices which operate the stopping-gear on the breakage or other failure of the yarn supply, and are automatically reset. The yarns A pass between co-axial rings M, N and support yarn-fingers B pivoted at B<2> and provided with adjustable tension weights B<4> The inner end B<3> of each finger engages a rod C sliding in a fixed part D. A small amount of variation in the tension of a yarn A is compensated for by the movement of the corresponding finger B, which causes the bight of the yarn to lap on the rod N with a varying angle of contact. Should a yarn break or slacken sufficiently to cause defective knitting, the corresponding rod C is moved upwards to swing a latch E about its pivot E<2> and thus release a catch F pivoted at F<1> to a part of the cover L. The catch F has a slot at right-angles to the movement of a slide G connected to the stopping-gear, the slide being normally held from movement under iufluence of a spring H by a screw G<10> which works in the slot. When the catch F is freed, so allowing the slide to move, and stop the machine, a roller G<6> or. an arm G' projecting from the slide runs over the cam-edge, of a lever J and depresses a spring-controlled plunger K. A plate, K<2> at the lower end of the plunger K is thus moved to the dotted-line position into contact with the arms B<3> and resets in the normal position any finger B the thread of which has been broken.
