Title: Improvements in or relating to reverse gears
IPC: F16H3/60
Filed: 1931-10-12
Abstract: 383,375. Friction clutches ; reversing- gearing. SNOW & PETRELLI MFG. CO., 25, Fox Street, New Haven, Connecticut, U.S.A.-(Assignees of Nabstedt, A. T. ; 46, Hall Street, Whitneyville, Hamden, Connecticut, U.S.A.) Oct. 12, 1931, No. 28342. Convention date, Feb. 3. [Class 80 (ii).] An epicyclic-type reversing-gear comprises at least one self-tightening clutch having a cone ring 39 split entirely through at at least one point 56, Fig. 3. The grip cone 39 is slidable on a sleeve gear 12, Fig. 1, into engagement with a female cone 38 on a plate 16, and during engagement it contracts so as to grip the gear 12 as well as the plate 16. The reversing-gear shown, suitable for marine propulsion, comprises sun gears 29, 28 fast on driving and driven shafts 10, 11, the gear 29 being in one with the sleeve gear 12. Interengaging planet pinions 27, 26 meshing respectively with the sun gears 29, 28 are supported in a cage comprising side plates 21, 22 adapted to slide on cross-bars 23, Fig. 2, which connect endplates 16, 17 of a freely-revoluble drum 18. Between the hub of the gear 28 and a female cone 44, Fig. 1, on the plate 22 is a second split-cone grip-ring 45. To effect solid forward driving, a sleeve 54 is actuated so as to thrust to the left plungers 51 passing through the endplate 17. This thrusts both cones 45, 39 into clutch engagement, the planet cage being bodily moved in the same direction. To reverse the drive, the sleeve 54 is moved the other way, freeing the clutches, and through a lever 55 thrusting a cam bar 31, Fig. 2, through a pin 31<1>. This acts to draw together the ends of a brake 30 so as to hold the drum 18 and cage against rotation and cause the gear train to act. A modification is described in which the second split cone clutch 45, 44 of Fig. 1 is replaced by a multiple-plate clutch.

Filed: 1946-09-23
Abstract: 621,700. Shoots and hoppers; loading, &c. ROBINS CONVEYORS, Inc. Sept. 23, 1946, No. 28468. Convention date, Oct. 12, 1945. [Classes 78 (i) and 78 (iv)] In a railway hopper car or the like the discharge of material therefrom is accelerated by means of a heavy mass, supported on the tops of the two side walls of the car, which when vibrated repeatedly rises and falls bodily out of and into contact with the tops of said car walls, the said mass being of such weight that its repeated falls cause the car itself to vibrate bodily. The apparatus shown in Figs. 2, 3 and 4 which is lowered onto the tops of the two side walls 3 of a railway hopper car, consists of two rectangular frames 5 and 6 which are resiliently connected by springs 18, 22. A motor 19 mounted on the 'frame 6 drives a shaft 11 carrying eccentric weights 12, which when rotated strike the heavy frame 5, causing it to jump out of and into contact with spaced shoes 17 resting on the tops of channel members 13, 14 which, as shown in Fig 2, are loosely connected with the main frame 5, to allow relative vertical movement, by bolts 15 engaging both a slot 16 in the frame 5 and the channel members 13, 14, which latter not only serve to locate the apparatus on the car walls but also receive the direct pounding of the frame and protect the walls from damage. A damping device 24, Fig. 2, is provided for braking excessive movement of the frame 6 relative to the frame 5 should the springs 18 not prove to be adequate. Specification 481,813 is referred to.

Title: Compatible single sideband radio transmission system
IPC: H03C1/60
Filed: 1957-09-12
Abstract: 868,952. Radio transmitting systems. KAHN, L. R. Sept. 12, 1957 [Sept. 26, 1956], No. 28767/57. Class 40(5) In a single sideband transmission system an input audio signal is supplied via a conductor 10 to a balanced modulator 16 which receives also a carrier-frequency signal from an oscillator 18, and the resultant double sideband suppressed carrier wave is supplied to a filter 34 which selects the upper sideband. The carrier frequency is supplied via an adjustable alternator 40 and is added to the single sideband signal thus providing a carrier plus sideband signal which is limited at 52 to retain only the phase modulated component and is amplified at 60. An adjustable delay network 50 is included between the circuit and limiters 52. The carrier plus single sideband signal is supplied via a cathode follower 106 to a product demodulator 100 where it is combined with the carrier supplied through an adjustable phase shifter 108, the resultant output being a replica of the audio input signal but including the phase shift introduced by the filter 34 &c. The output of the demodulator 100 is supplied via a cathode follower 118, adjustable attenuator 78, amplifier 88, and modulator 88 to amplitude modulate the phase modulated signal from the amplifier 60 in a unit 66, thus reproducing the single sideband plus carrier wave signal in amplified form. The signal is stated to be suitable for reception either by a single or double sideband receiver of conventional type. To further reduce distortion in the output signal, Fig. 3 (not shown) an envelope signal is derived by an additional detector supplied by the filter 34 and the output filtered to select frequencies above say 5 kc/s. which are combined with the signals from the product demodulator 100 before modulation of the limited signal at 66. A second sideband filter may be inserted in the conductor 94. In further modifications distortion is reduced by increasing the effective phase deviation of the limited signal, Figs. 5 to 8 (not shown). U.S.A. Specification 2,666,133 is referred to.

IPC: G21D5/02
Filed: 1956-09-20
Abstract: 876,850. Nuclear power plant. MITCHELL ENGINEERING Ltd., JACKSON, G. G., and COLES, H. J. Dec. 20, 1957 [Sept. 20, 1956; Dec. 4, 1956], Nos. 28826/56 and 37096/56. Class 39(4). [Also in Group XXVI] A reactor producing steam and a steam turbine are mounted together within. a common radiation shield. The reactor core, comprising fissile elements 42 all housed within a cylinder 12 containing water, rotates about a fixed shaft 11, the moving vanes 22 of the turbine co-operating with fixed vanes 23. Steam generated in the reactor core and expanded in the turbine is exhausted at 33 to a condenser and the condensate returned through 34 to the reactor cylinder, a controllable amount being bled off at 28. Reactivity is controlled by raising or lowering neutronabsorbing elements carried on rods 45, these rods being moved by screw - and - nut mechanism 49, 48. During operation with the centrifugal force acting on the water it is necessary to maintain sufficient water to cover the fissile elements, therefore a scoop 52 and a device 51 responsive to differential hydraulic pressure control this amount of water. The rotating parts have labyrinth seals 26, 21 and the output from the turbine is transmitted through worm gearing 56, 57. The fissile elements use slightly enriched uranium. The Specification mentions without detail the possible counter rotation of the central shaft and the fact that rotation may be about a horizontal axis. The reactor is described as being particularly suitable for marine use.

Title: Superconductive amplifier
Inventor: SCHLIG EUGENE STEWART
IPC: H03F19/00
Filed: 1961-08-11
Abstract: 973,437. Superconductive amplifiers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1961, No. 29019/61. Heading H3B. In a superconductive amplifier, gate conductors 20, 21, Fig. 3, are fed in parallel by a source 24 of constant current 2I 1  where I 1  is a little less than the critical current Ic necessary to drive a gate conductor resistive. Current in series connected control conductors 22, 23 tends to aid and to oppose respectively the magnetic effects of the gate conductors 20, 21. If control current flows from terminal 27 to terminal 28, gate 20 goes resistive and current is shifted from gate 20 to gate 21 until both gates are again superconducting but carry unequal currents. The current shifted is a measure of the control signal. In Fig. 5, a high inductance 34 and a low resistance 3 are connected in parallel with the gate conductors 20, 23. The current supply is adjusted to be slightly greater than the sum of the critical current for the two gate conductors. Automatically, low resistance branch 34, 35 takes current sufficient to reduce the current in conductors 20, 21 until at least one conductor becomes superconductive. In Fig. 6, series connected control conductors 57, 58, 59 and 60, 61, 62 control the shift of current between parallel connected gate conductors 43, 44, 45 and 60, 61, 62. Element construction.-A gate conductor 10, Fig. 1, comprises a thin film mounted on a planar backing 12. A thin film control conductor 11 narrower than the gate conductor is mounted on the gate conductor with an intervening layer of insulating material.

Title: Improvements in self-sealing releasable couplings for use in fluid pressure lines
Inventor: LOVE JOHN
IPC: F16L37/252
Filed: 1959-08-25
Abstract: 888,541. Pipe couplings. K. A. C. Ltd. Nov. 23, 1960 [Aug. 25, 1959; Sept. 2, 1959], Nos. 29089/59 and 30010/59. Class 99(1). A self-sealing coupling for detachably connecting pipes in fluid-tight intercommunication, comprises two tubular main parts 1, 2 at least part of one of which is rotatable relatively to the other about the axes of the coupling parts for effecting the connection and disconnection of such parts, a swivelling disc or butterfly-type closure valve 7 for at least one of the main parts, and means, operating as a result of relative rotation of the relatively rotatable parts of the coupling, for automatically closing the valve or valves when the coupling parts are disconnected and opening the valve or valves when such parts are connected. As shown in Fig. 1, the part 1 is relatively rotatable with respect to a sleeve 1b and terminates in a socket 3 provided with bayonet slots 4 which receive radial pins on thepart 2. Within the socket are dogs 14 for engagement with complementary dogs 13 on the part 2, and a groove housing a resilient sealing ring 6. The valve disc 7 is mounted on trunnions 8 and carries a sealing ring 11 for co-operation with a part spherical seating 9. A sleeve 2b retained in and rotatable relatively to the part 2, carries a valve 15 mounted on trunnions 16 and including resilient arms 19 which carry driving pins 21 that work in arcuate slots 22 in the wall of the sleeve and extending into longitudinal grooves 23 in the wall of part 2. Connection of the parts is effected by introducing the part 2 into the socket 3 to engage the dogs 13, 14, and to enter the pins into the slots 4, and the relatively rotating the socket and part 2. Such relative rotation causes the pins to move around the slots 4 to lock the coupling parts together and relative rotation of the sleeve 2b and part 2 to thereby cause the pins 21 to move along the slots and grooves 22, 23 and effect rocking of the valves 7, 15 about the trunnions thereof. In a modification, the valve disc 44, Fig. 5; has mounted thereon a resilient metal sealing disc 48 for co-operation with part-spherical seating 43 and is provided with a driving peg 50, which is engageable in an arcuate groove 61 in the similar valve disc 54. Both valve discs are mounted on pivot pins 45 rotatable in bosses 47. Upon connection of the coupling parts, the valve discs are brought into face-to-face abutment and relative rotation of those parts causes co-operation between the peg 50 and groove 61 to rotate the valves wherein the planes of the latter are parallel with the axes of the coupling parts. Specifications 732,442, 735,271, 736,879, 781,761, 790,625 and 835,005 are referred to.
