Title: Improvements relating to gas turbine engine accessories
IPC: F01D15/10
Filed: 1961-11-13
Abstract: 987,878. Gearing for stopping and starting machinery; toothed gearing. GARRETT CORPORATION. Nov. 13, 1961 [Nov. 14, 1960], No. 40566/61. Headings F2L and F2Q. [Also in Divisions F1 and H2] A gas turbine engine accessory comprises an output-input shaft for connection to the gas turbine engine, an electric generator including a rotor mounted on a rotor shaft, an air turbine having means for coupling it to the rotor shaft to drive it, and gearing connected to the outputinput shaft and having means for coupling it to the rotor shaft to drive the generator or be driven by the air turbine through the rotor shaft for starting. The unit shown comprises an output-input shaft 44 which is connected to the shaft of a gas turbine engine and may be used either to drive the gas turbine engine for starting purposes or to be driven by the gas turbine engine so as to drive the electric generator 11. The unit comprises an inward radial flow air turbine 10 having a rotor 12, the shaft 13 of which is connected through gearing 31, 32 and a one-way clutch 35 to a rotor shaft 36 on which is mounted the rotor 37 of an electric generator. The shaft 36 is also connectible to the output-input shaft 44 by means of epicyclic gearing, the gearing comprising a sun gear 41 mounted on the shaft 36, planet pinions 42 carried by a planet carrier 47 and an internal ring gear 43 carried by the shaft 44. The planet carrier may either rotate freely when the brake member 53 is disengaged as shown in which case no torque is transmitted between the shafts 36 and 44, or it may be secured when the brake is engaged so as to transmit torque. The brake member 53 is held out of engagement with the planet carrier 47 by means of springs 56 but may be engaged therewith by supplying pressure fluid to the chamber 52 which causes the brake member to move to the left. For use in starting, the brake 53 is engaged and air is supplied to the air turbine which therefore drives the shaft 44 and rotates the gas turbine engine. When the engine starts it drives the shaft 44 and so the shaft 36 and electric generator, the one-way clutch allowing the air turbine rotor to come to rest. The unit may also be used to provide current for preliminary checking before the engine is started, the brake 53 then being disengaged so that when air is supplied to the air turbine 10, the latter simply drives the generator. The generator is of the homopolar type and generates current of all frequencies the current being converted to uniform frequency in a static converter.

Title: Fibre bale and process for the production thereof
IPC: B65D85/07
Filed: 1961-11-15
Abstract: 967,470. Packaging fibrous materials. SPINNFASER A.G. Nov. 15, 1961 [Nov. 16, 1960], No. 40867/61. Heading B8C. A bale of fibrous material, e.g. cotton or staple rayon, is formed by compressing the fibre in a baling press and, while it is compressed, introducing it into a tube of foil sheet which may be reinforced with a lining of gauze fabric so that the fibre is held, without bands or straps, by the surrounding foil sheet. The ends of the tube are closed, e.g. by welding. A fork-lift truck may be used to extract the compressed fibre from the baling press and to transport it to a position above a packing device where a foil sheet in tubular form is drawn up over the bale, Fig. 1 (not shown); or the bale may be taken from the press by a multi-prong clamp, holding the bale transversely, transferred to a 2-prong fork holding it longitudinally, Fig. 2 (not shown), and a tube of foil sheet drawn over the bale. Again, plates, Fig. 3, may be held magnetically on each plate of the baling press, the fibre compressed between them, the plates connected by means of webs to form a mould in which the fibre is removed from the press and the fibre thereafter pushed by a plunger out of the mould into a sleeve. In a further modification, the bale is strapped while in the press, Fig. 4 (not shown), removed, and set up vertically above a bag, the straps being released as it is slid downwards into the bag. Alternatively, Fig. 5b, a foil sheet is fixed on each of the plates of the baling press, the sheets being welded or stitched together at 14 round the fibre after it is compressed; the side members are closed at the ends of the bale after the bale is removed from the press.

Title: Electrical structures comprising solder barrier
IPC: H01L23/528
Filed: 1975-10-09
Abstract: 1484435 Printed circuits INTERNATIONAL BUSINESS MACHINES CORP 9 Oct 1975 [23 Dec 1974] 41374/75 Heading H1R [Also in Division B3]  A supporting dielectric substrate 14 contains pins 15 connecting to a circuit board superimposed at higher level and carries a circuit pattern 10 formed of alloyed silver and a platinum group metal wettable with solder and having plural connecting areas 12. The pattern is silk screen printed from a paste containing vitreous frit and fired, and may be coated with an unsolderable pattern 16 containing gold and vitreous frit which is printed, dried, and fired. The solderable area is coated by dipping in tinlead solder, and a microminiature component, e.g. integrated circuit 20 with solder contacts is positioned on the connective pattern 12. The assembly is then heated to soften the solder for attachment and cooled (Figs. 1, 2). The pattern 10 is of Ag-Pt alloy, e.g. Ag-Pd, and the metals may be Pt, Os, Ir, Ru, Rh, admixed with vitreous frit. CuO or PdO may be added. In superimposition of the patterns, a fired conductor 21 is overlain on substrate 14, and a dried gold barrier is deposited thereupon. After further firing, gold diffuses from the barrier into conductor 21 and silver into the barrier to form a gold rich gold silver composition 23 (Fig. 4B). On application of a lead-tin solder the conductor 25 is depleted to lead/palladium with free silver, and the solder 26 wets the conductor and abuts the barrier 23, and the underlying gold rich layer 24 prevents entry of corrosive elements, e.g. sulphur into the underlying silver. Practical examples and test results are given.

In a centrifugal friction clutch of the parent Specification wherein lined clutch shoes 4 pivoted on an axially free driving carrier 2 and having conical and auxiliary lateral friction surfaces are centrifually moved, to a limited extent, against return springs to engage two driven plates 5, 6 respectively axially fixed and movable, the driven plate 6 is axially acted on by a disengaging device comprising a release lever and plate 18, 15 by pressure springs 14 reacting on a drum 7 rotatably carrying the driven plates, and, for towed starting or engine braking, by an inertia-drag screw-and nut device in which the screw 9 is integral with an axially fixed driven shaft 10, the nut 8 has fast thereon the drum 7 and is movable on the screw between axial stops 12, 13, and the driven plate 6 rotates with the nut but has axial freedom thereon limited towards the shoes by a stop 11. When the driven shaft overruns the driving shaft the inertia of both driven plates, the drum 7 and the spring 14 effects retardation of the nut relative to the screw and axial movement of the nut to move the driven plate 6 into contact with the lateral friction surfaces of the shoes. Further nut retardation ensues due to this frictional engagement until slip ceases. In this condition the clutch may be disengaged at will by the device 18, 15. As soon as the driving shaft speed rises in respect of the driven shaft the clutch is disengaged by axial movement of the nut away from the shoes to withdraw the driven plate 6 which moves to the stop 12. With further rise in driving shaft speed the clutch is engaged centrifugally. The driven and driving shafts may be arranged following in-line (Fig. 2, not shown).

Abstract: 967,987. Road traffic signals on vehicles. FORD MOTOR CO. Ltd. Nov. 7, 1962 [Dec. 19, 1961; Dec. 26, 1961], No. 42049/62. Heading G4Q. In a vehicle turn signalling mechanism, means are provided for sensing small movements of the steering member about the zero position, and for returning the turn signalling switch to its inoperative position when a number of such movements have been sensed. In a first embodiment, Fig. 3, an automatic reset mechanism comprising pins 13 and pawls 14 is provided to automatically reset the turn indicator switch member 11 on straightening the steering member 12 after a turn. If after signalling, say, a left hand turn the steering member 12 is returned to its zero position without being turned sufficiently for one of the pins 13 to pass a pawl 14, the switch member 11 is not reset, and pawls 31 or 32 engage with the ratchet wheel 22. Any subsequent movements of member 12 in a clockwise direction will then cause the ratchet wheel 22 to rotate in an anti-clockwise direction, return motion of this wheel being prevented by pawl 35. As the wheel 22 is gradually rotated by small turns of the steering member in maintaining the vehicle along a desired path, cam 18 moves with it until it engages with member 4, further pressure of pawls 31 or 32 rotating ring 19 to reset the switch member11 The ratchet 22 then disengages with pawls 31, 32, 35 and returns to its initial position under the action of a spring 25. In a second embodiment, Fig. 6, pawls 134 engage with ratchet 133 and the rotations of the steering member turn ratchet 133 until the end of slot 131 engages with pin 142 to rotate the switch member 107 to its inoperative position disengaging pawl 134. Ratchet 133 is then returned to its initial position under action of spring 138.
