Title: Conference circuit for private automatic telephone exchange systems
Inventor: FOSTER WILLIAM GORDON
IPC: H04M3/56
Filed: 1954-10-08
Abstract: 798,904. Automatic exchange systems. TELEPHONE MANUFACTURING CO., Ltd. Sept. 8, 1955 [Oct. 8, 1954], No. 29090/54. Class 40 (4). A subscriber is given a conference facility by the modification of a fault circuit associated with a seized finder-selector link and the inclusion in his line circuit of a relay which is operated by a relay in the fault circuit when the subscriber dials a conference digit and makes a connection with a conference circuit while releasing the seized finder-selector link and marking the subscriber's line busy. Figs. 1 and 2 show subscribers' line circuits respectively without and with a conference facility provided by a relay PG which operates in conjuncton with a permanent glow alarm circuit shown in Fig. 3 and a forced release circuit associated with a final selector circuit shown in part in Fig. 4. When either subscriber lifts his receiver a preselector or line finder is started by line relay L to make a connection with a finderselector link causing line relay A to operate and actuate relay B. Relay B returns earth on the subscriber's P wire and makes a circuit for a relay KO which operates after a time determined by Ó delay DE, the circuit being broken when A falls back in response to the first impulse. If a subscriber with the line circuit of Fig. 1 fails to obtain a finder selector link, no earth is returned over the P wire and the cut-off relay K responds and locks up, after a time determined by thermistor TH1, to release L and operate relay PGA which actuates a delayed permanent glow alarm. If, having obtained a finder-selector link, the subscriber does not dial within the time determined by the delay DE, relay KO responds releasing relay A and removing earth from the P wire. With earth on the P wire both L and K are energized in series, but when earth is removed L falls back while K is held over l2 and k1, and then locked up over l4, k4 and l1. With K operated and L released, the alarm is set off and contact k2, by taking battery off the P wire, holds the line engaged to incoming calls. In the circuit of Fig. 2 which has a conference facility, the relay PG pulls up in series with the holding circuit for K over l4, k4 and l1, battery being removed from the P wire by pg4, and the alarm circuit being set off by PGA which is energized over a contact cn. To set up a conference connection a subscriber dials a predetermined digit which by any known means closes a contact x, Fig. 4, to operate the relay KO without waiting on the delay DE, and to operate a relay CN which prevents operation of the alarm circuit and locks up against the release of x over pg3; at this stage K and PG are operated and L is released as described above. Contacts pg1 and 2 connect with a conference line and contact pg4 holds the line engaged by removing battery from the P wire. Parties to the conference are fed with speaking current by way of relays PG and K.

Title: Variable speed drive transmission
IPC: F16H15/44
Filed: 1956-09-24
Abstract: 821,860. Variable-speed gearing. ROLLER GEAR CO. Inc. Sept. 24, 1956 [Sept. 23, 1955], No. 29113/56. Class 80 (2). Variable-speed friction gearing comprises balls 23 capable of free rolling movement in all directions and spaced by rollers 24 in a spider 25 and arranged between coaxial pairs of inner and outer races, of which the outer races 11, 13 are carried by a driving- shaft 5 and are movable apart or together to vary the gear ratio while one inner race 14 is fixed to a driven shaft 7 and the other inner race 15 is slidably keyed on shaft 7. The difference between the radius of curvature of the outer races 11, 13 and the radius of the balls 23 is at least twice the difference between the radius of curvature of the inner races 14, 15 and the balls 23. The outer races may, therefore, be conical. The race 11 is secured to a piston 10 slidably keyed on shaft 5 and is slidably keyed to a cylinder 12, to which latter the race 13 is fixed. Contact pressure between the balls and races is provided by a spring 50 and by loadresponsive means comprising balls 18 in helical grooves on members 16, 17 mounted on shaft 7 and on an output shaft 6. Hydraulic ratioadjusting means comprises a manually or automatically (by engine speed, torque or fuel supply) operated sleeve valve 38 controlling supply of oil from a gear pump 40, 41 driven by shaft 5 to a space 46 in the cylinder 12, so as to move the outer races apart or together. In the planetary form shown in Fig. 1, affording both forward and reverse drives, the spider 25 is driven in the same direction as shaft 5, but slower from cylinder 12 through a spring-loaded friction coupling 30 and planet gearing 32, 34, 35, 36. In the event of overloading, the friction coupling 30 slips. In the non-planetary form shown in Fig. 5, the spider 25 is stationary or is frictionally secured to the casing so as to be capable of slipping at overload, and the hydraulic pressure acts positively both in forcing the races 11, 13 together and in forcing them apart. In this case, the cylinder 12 has two pressure spaces 46, 72, space 46 being bounded by piston 10 and space 72 by a piston 63 rigidly connected to piston 10, the control sleeve valve 38 controlling the supply of oil to the two spaces. By connecting the hollow shaft 6 of the gear to a gear annulus 83, shaft 5 to a sun-gear 85, and a planet carrier 86 to a final output shaft 88, both forward and reverse drives of the latter can be obtained.

Abstract: 536,238. Gas turbines. HEPPNER, F. A. M. Nov. 6, 1939, Nos. 29487/39 and 122/40. [Classes 110 (i) and 110 (iii)] The gas turbine 4, Fig. 1, and air-compressor 3 are on one shaft. The useful-power shaft 2 carries a ring of outward flow turbine blades 8 though which the air-compressor discharge passes and this provides the only power connection between the turbine and useful-power shafts. Fuel is admitted at 16 and is burnt in a divergent chamber 11. The turbine comprises a ring of inward flow guide blades 10 and a double axial flow stage 9. Air, flowing between the combustion chamber 11 and the walls 13, passes through the hollow centres of the guide blades 10 before mixing with the gases from the combustion chamber. The combustion chamber wall is divided by three longitudinal slots and the three wall portions are given a slight and overlapping scroll form. Fluid pumps 28, 31 form speedresponsive devices on the turbine and usefulpower shafts and deliver pressure fluids to cylinders 30, 34 which control the fuel valve. A hand control 37 is put in the connecting mechanism. The fluid of the pump 28 is lubricating oil and that of the pump 31 may be the liquid fuel. In the construction shown in Fig. 3, the turbine and pump rotors have fluid channels 22, in lieu of blades, which lead alternately from opposite sides of the rotor and the turbines'have rings of axial-flow blades 23. Passages 26, 24 for cooling air are provided in the turbine rotors and they have outlets 240 in the rotor peripheries. The blades 8 for the useful-power shaft 2 are secured by peening in a disc 19a and in a ring detachably secured in a groove in a disc 19. The latter ring is carried by radial pins on a spider 18.
