Patent GB-190707785-A (GB)
Title: Improvement in Duplexing Telegraph Lines.
Inventor: KITSEE ISIDOR
Filed: 1907-04-03
Granted: 1908-01-23
Abstract: 7785. Kitsee, I. April 3. Telegraphs.-In a system of duplex telegraphy, signalling is effected by transmitting momentary current impulses of substantially the same duration and intensity and of both polarities over the line ; the depression of the transmitting-key causes an impulse to be sent over the line, and the opening of the key causes an impulse of opposite polarity to be transmitted. The home receiving relay is prevented from responding to the transmitted impulses by joining across its terminals the secondary of an induction coil, in which impulses that neutralize the effect of the transmitted impulses on the home receiving-relay, are induced when the transmitting-key is opened or closed. At each end of the cable 1 are placed, in series between the cable and earth, the relay 2, a battery 7, a condenser 14, and a battery 15 set in opposition to the battery 7. When the transmitting-key 11 at the station A is depressed, the battery 7 is shortcircuited through the primary of the induction coil 30, and owing to the short-circuiting of the battery the potential of the line at the station A is altered, so that an impulse flows over the line circuit, causing the tongue of the relay 2 at the receiving-station B to strike one of the stops 25, with which it remains in contact till, on the opening of the key 11, an impulse of opposite sign is transmitted over the line circuit causing the relay tongue to move over into contact with the other stop. In this manner, the local circuit at the receiving-station may be kept closed as long as the transmitting-key is closed, and thus signalling may be effected in the ordinary manner by dots and dashes. To prevent the home receiving-relay from responding to the transmitted impulses, the secondary of an induction coil 30, the primary of which is contained in the shunt circuit containing the transmitting-koy, is joined across the terminals of the receiving-instrument. When the transmitting-key 11 is opened or closed, an impulse flows in the line circuit which tends to actuate the home receiving-instrument ; but at the moment of opening or closing the shunt circuit containing the induction coil 30, by the operation of the transmit- .ting-key, an impulse flows in the secondary circuit of the induction coil which includes the home receiving-relay. This induced impulse may be made to neutralize the line impulse so that the home receiving-relay is not actuated. In order that the strength of the induced impulse may be controlled, the primary of the induction coil is made capable of sliding in the secondary coil.

Granted: 1909-02-11
Abstract: 9213. Lake, W. E., [Vivian, S.]. April 28. Pressure-regulating valves; actuating valves.-In a valve apparatus for automatically controlling the rate of flow of a fluid by maintaining a constant difference of pressure on the two sides of an orifice or a valve comprising a screw-adjusted sliding gate valve 12 and an automatic throttle valve 19, 20, a control valve 14 is provided and is actuated by the difference cf pressure on the two sides 16, 26 of the valve 12, operating through connexions 44, 45 on opposite sides of a diaphragm 40, or a piston. The diaphragm is weighted at 41 in accordance with the difference of pressure to be maintained on the two sides 16, 26. If for any reason the rate of flow increases, the increased difference of pressure, acting upon the diaphragm 40, raises the valve 14. In this position, fluid under hydraulic pressure arriving by the conduit 56 flows through the valve 14 and through the conduit 57 to the underside of the plunger 23 of the valve 19, 20, thereby raising the latter valve to throttle the flow. If the flow decreases, the valve 14 operates to connect the underside of the plunger 23 to the drainage conduit 58, whereby the valve is allowed to open by gravity. Scales and pointers are used, as shown, to indicate the positions of the valves 12, and 19, 20.

Roasting and calcining furnaces; charges, agitating.-Relates to aircooled rabbles for oreroasting furnaces of the kind described in Specification No. 17,370A, A.D. 1905, and to the arrangement, construction, and method of attaching their teeth. In a furnace having superposed chambers as shown in Fig. 1, the rabble arms 3 are arranged on opposite sides of the air-supplying shaft 1 and are secured thereto by a key 8 fitting in a recess 7, Fig. 24, formed on the horizontal upper surface of the arm. The sides and bottom of the rabble arm are tapered and the opening in the shaft into which the arm is inserted may be of such inclination at the bottom that a space is formed which may be used for a clay filling, or for the insertion of metal strips to adjust the inclination of the arm. Air from the central shaft 1 enters a rabble arm through a hole 9 registering with a similar hole in the shaft, passes under the oblique part 11 of a central partition 10, flows towards the outer end of the arm and around the end of the partition, and returns to the shaft through a similar hole 9 above the oblique part of the partition. The partition 10 may extend to the outer end of the arm in which case the space on each side is filled with non-conducting material. Each rabble arm is provided at the back and front with flanges 12, 13, Figs. 23 and 24, which have projections 14, 15 tapering towards the inner end of the arm. At this end, larger projections, tapering in the opposite direction, are formed to receive jaws 17, Fig. 22, on the top of an oblique tooth 18, which is employed to direct the ore outwards and prevent it from falling between a sleeve 2<a> and the central shaft. This tooth and the innermost front tooth 23, Figs. 1 and 24, are passed over the flanges on the arm from the outer end, stop pieces 19 being provided for the oblique tooth at the ends of the flanges. All the other teeth are placed upon their projections from the inner end of the arm ; stops 27 are arranged either as shown or upon the same side of the flanges as the projections 14, 15. The back teeth 20, Figs. 20 and 23, are rectangular in front elevation and each is formed with a recess 22 to engage one of the projections 14. Each front tooth is provided with a cross-piece 24, Figs. 23 and 24, which is connected by a shank 23 with a jaw 25 having a recess to engage one of the projections 15. The teeth are so arranged that the front teeth 24 pass beneath the ridges formed in the ore by the back teeth 20 and leave the surface of the material approximately level. To prevent the teeth from shifting from their positions, retaining bars having depending projections are provided, and the inner ends of these bars are inserted in recesses 30, Fig. 22, formed in the jaws 17 of the oblique tooth 18.

D. 1909, dated Jan. 25.] Aerial machines without aerostats; aeroplanes ; steering and balancing. - In a device for automatically maintaining the stability of aeroplane machines, two side planes A, A<1> and a rear plane B are provided, and are so interconnected by cords that an upward movement of the tip of one side plane, say the plane A, produces (1) a downward motion of the front edge of that plane, (2) a downward motion of the tip and an upward motion of the front edge of the opposite side plane A<1>, (3) a downward motion of the right-hand tip and an upward motion of the left-hand tip of the rear plane B. Provision may be made to prevent the tips of the rear plane from moving upwardly, and the planes may be moved manually for steering. The side planes A, A<1> are curved longitudinally and transversely and are pivoted on a universal joint at a, a' to the frame of the machine. The rear plane B is secured at its forward edge b to the machine. The tips a<2>, a<3> of the planes A, A<1> are connected by cords a<4>, a<5> passing over fixed pulleys x. The forward edge a<6> of the wing A is connected by guided cords a<7>, a<8>to the tip a<2> of the wing, and by the cords b<3>, b<4> to the opposite tip b<2> of the rear plane. The cord b<3> may be provided with an adjustable spring c. The forward edge a<9> of the plane A' is similarly connected to the tip a<3>, and to the tip b<1> of the plane B. Instead of connecting the tips b<1>, b<2> to the planes at the points a<6>, a<9> they may be connected directly to the tips a', a<3>. In the form shown, the tips of the plane B are prevented by stops d from moving upwardly, the cords b<3>, b<5> having springs c to permit this. One or other of the tips of the rear plane can be depressed by cords c<1>, c<2> passing round a drum on the operating-handle C so that the movements of the planes can be made manually. Springs c are introduced into the cords c<1>, c<2> to prevent interference with the automatic action of the device. In another form, the auxiliary planes are divided into parts 1, 2, Fig. 9, which are hinged to the main supporting-aeroplane X on longitudinal and transverse axes, respectively. The planes are interconnected and operate as described above. According to the Provisional Specification, No. 23,347, the balancing device consists only of the two side planes, the tailplane and the connexions thereto being omitted. These planes serve as the main supporting-surfaces, and are flexible at the tips,
