Title: Improvements in energy removal from superconducting coils
IPC: H02H7/00
Filed: 1965-09-27
Abstract: 1,101,670. Arcing preventing in switches. GENERAL ELECTRIC CO. 27 Sept., 1965 [1 Oct., 1964], No. 41036/65. Heading H1N. [Also in Division H2] An arrangement for protecting a superconducting coil 2 connected in an operating circuit and subject to transition to a state of normal conduction, comprises sensing means for detecting a transition and controlling switching means for disconnecting the coil from the circuit, and voltage-limiting energy transfer means connected across the coil to limit the potential across the coil while removing energy therefrom. The sensing means may comprise a voltage pick-up coil 7 associated with the superconducting coil and controlling the switch 4 through an amplifier and an electronic control device 8. The energy transfer means may comprise an anode controlled thyratron 10 in parallel with a capacitor 11 and in series with a diode 12. When normal conduction occurs, the switch 4 is opened and the capacitor 11 charges to the ignition voltage of the thyratron 10. When the thyratron fires, the voltage across it is reduced to its operating value so reducing and limiting the voltage across the superconducting coil 2. Current from the superconducting coil flows through the thyratron until the energy of the coil has been released. A triac, a silicon-controlled rectifier or other solid state device may be used in place of the thyraton. Reference is also made to the use of ignitrons and voltage dependent resistors.

Abstract: 884,596. Gas turbine plants. GENERAL ELECTRIC CO. Dec. 19, 1958 [Dec. 31, 1957], No. 41041/58. Addition to 809,811. Class 110 (3). A gas turbine plant as described in the parent Specification comprising in a common casing an axial flow compressor feeding a combustion chamber supplying combustion gas to a turbine driving the compressor and a useful output turbine positioned downstream of an coaxial with the first turbine and having a curved tailpipe which communicates with the atmosphere through an end opening the axis of which makes an angle of less than 90 degrees with the axis of the casing and is provided with a depression in its wall on the outside curvature which supports a bearing for the turbine output shaft, has an inner hollow shell which extends from inside the casing through the end wall of the depression and supports the power turbine end shaft. The tail pipe assembly 10 includes a free power turbine 22 having a shaft 24 which extends through the rear wall 28 of the tail pipe casing shell 29 to reduction gear-box. The tail pipe 10 is made up of an outer shell 29 and an inner cylindrical shell 30 which is supported from the outer shell by a floor portion 39 of a depression 36 in the tail pipe 10, by a flange 50 and by three struts 54. A frusto-conical housing 55 is mounted and located within the inner cylindrical shell 30 by an integral end wall 57 having a flange 66 which is bolted to a flange 68 of the inner shell. The aft end of the housing 55 is slidably mounted in the inner shell 30 by means of co-operating surfaces 74, 80. The shaft 24 is supported by bearings 82, 84 mounted in the walls 57, 58 respectively. The inner shell 30 also supports a baffle disc 98. Compressed air from the engine compressor is passed through a duct 122 into the chamber 124 formed between the inner shell 30 and housing 55. From this chamber 124 the cooling air flows through holes 120 into chamber 104, where it cools the bearing 82, thence through aperture 96 and over the rear surface of the turbine disc 102 into the stream of exhaust gases leaving the turbine. Cooling air also leaks between the surfaces 74, 80 over the outside surface of the end wall 58, and bearing 84. The bearings are lubricated by oil mist formed in the chamber 126 from oil issuing from conduit 129.

Title: Methods and apparatus for roll-forming gears
IPC: B21H5/04
Filed: 1971-09-02
Abstract: 1339809 Rolling gears GLEASON WORKS 2 Sept 1971 [16 Nov 1970] 41044/71 Heading B3M A gear blank 12, Fig. 9, is roll-formed or rollfinished by a die 10, the die being fed relative to the blank by a pivotal motion about an axis 22 substantially coincident with a common normal to the axes 16 and 18 of the blank die. The blank and die are rotated about their axes during rolling. The pivotal feeding movement is effected by an hydraulic ram 82 which has a pair of forks 83 embracing a support 80 for the die. Each fork is guided between a fixed slide 85 and a pivoted slide 86 mounted on the support. The die 10, Fig. 10, is driven through gearing 60, 64, 92 and 94 from a driving shaft 95, and the blank 12 is driven in synchronism, through gearing 62, 74, 70 and 66, with the same shaft. The gear 66 can be arranged to move axially during rolling by means of an arm 96, so that the speed of the work does not quite match that of the die. This enables the helical infeed of the die to be controlled, and teeth having unbalanced profiles to be produced. The movement of the arm 96 is controlled by a rod pivoted to the arm and having a roller 102 at its end. The roller engages a spring-loaded wedge 98 which moves axially in response to rotation of a cam 100 of suitable profile. The die 10, Fig. 6, may be provided with shrouds 42 and 52 for limiting axial spread of the workpiece teeth during rolling. It is possible to feed the die axially in addition to its pivotal motion. Only one of the die or blank may be positively rotated, while the other is rotated frictionally or has a braking force applied to it.

Title: Adaptive addressing systems for airbourne data systems
IPC: G01S13/74
Filed: 1974-09-20
Abstract: 1423126 Selective signalling BENDIX CORP 20 Sept 1974 [7 Nov 1973] 41094/74 Heading G4H In a co-operative data system, messages from a master station to a remote station which has a relatively long address normally include a relatively short address assigned to the remote station; and the master station periodically transmits an " all call " directed to all remote stations within its sphere of influence which have not been assigned a relatively short address, such a remote station responding with its relatively long address, to which the master station responds in turn with a relatively short address and a truncated portion of the relatively long address, the remote station memorizing the relatively short address as its assigned address. The remote station signals its acceptance of the assigned address to the master station by sending it back. If this acceptance indication is not received by the master station, the latter repeats the assignment message, and if acceptance is still not indicated, removes this assignment from its memory. Routine messages in both directions between master and remote stations contain the assigned address and data. Data may also be included in the acceptance message. All messages also include a preamble (for synchronization), control bits indicating the type of message, and parity. The " all call " message includes an " all call " address. Each remote station includes receive and transmit shift registers with an address comparator associated with the former. The master station may be a ground station and the remote station may be aircraft, the relatively long address being addresses unique worldwide, and the relatively short addresses being unique within the sphere of influence of the ground station. Use in aircraft to satellite communications is also mentioned.
