Patent GB-191409105-A (GB)
Title: Improvements in Telephone Exchange Circuits.
Filed: 1914-04-09
Granted: 1915-07-08
Abstract: 9105. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. April 9. [Addition to 11,251/10 and 4698/12.] Semi - automatic exchange systems. - Relates to modifications of the call - distributing system described in the parent Specification, in which a preliminary selector which has extended a call to a relief position, all the distributing-lines of the ordinary positions being engaged, is started moving again if one of the distributing - lines becomes idle before the call is answered. The present improvements are intended to avoid or reduce the delay .in re-starting the selector. I n the arrangement shown in Fig. 1, a preselector W is stopped on the contacts a, b, c, connected to the jack k at the relief position H, by a circuit through the relays PR, B, this circuit being controlled by the contact g of a relay R which is energized when all the distributing lines V1, V2, &c. are engaged. The relay B locks itself in series with a relay Y which prepares the circuit of a re-starting relay U. If the call is attended to at the relief position H, the relays B, Y are cut out, and the relay PR is locked at a contact of the jack k; but if, prior to this, a distributing-line V1 or V2 becomes disengaged, the relay R completes at its back contact h the circuit of the relay U, which at once unlocks the relav PR so as to start the switch W into motion again. It will be seen from the arrangement of the contacts of the relays Y, Y1, Y2, &c., that however many pre-selectors may be offering unanswered calls for attention at the relief position, only one of them is re-started when a distributing-line becomes free, and that in the matter of re-starting, a pre-selector is given preference over all the pre-selectors to the right of it. A modification is described in which the pre-selectors are given preference in rotation, instead of from left to right. In a further modification, the calling lines are divided into sub-groups, each of which has a single locking-relay Y and re-starting-relay U. A further arrangement is described which consists in a slight modification of that shown in Fig. 2 of the parent Specification, the effect being to quicken the operation of the switch used to control re-starting.

Abstract: 21,219. Duckett, Morrison, & Co., Morrison, J. W., and Holt, T. W. Oct. 20. [Cognate Application, 4773/15.] Winding-machines; spindle-driving apparatus; stop-motions.-In a winding-machine in which each spindle is separately driven and separately controlled by a cam to give the vertical movements to form the cop, a plate or like spring e, Fig. 7, is interposed between the cam c and the spindle a to prevent jerking or rebounding of the spindles. The spindles a are similar to mule spindles and slide vertically in rails a<1>, a<2>. The yarn guide j<1> is carried by a bracket j mounted upon a threaded rod h, pivoted at its upper end h<1>. A projection j' on the bracket j rests against the surface of a cone k during the formation of the cop-bottom. A contact disk i<1> governs the rise of the bracket on the rod h. The cone k has a varying taper and can be turned on its axis k' to vary the form of the cop-bottom. When the bottom is completed, the finger j<2> is raised out of engagement with the cone, and the rod h swings aside, its lower end coming into contact with a stop h<5>. The spindles are driven from the tin-roller shaft 9 through constantly rotated friction sleeves l. The sleeve l, Fig. 2<a>, is loose on a spindle l<1> carried by a bracket l<2>, which is pinned to a pivot l<3>. A lever l<6> is connected by a link l<5> to the lower end of the spindle l<1>, and a notch l<2> is cut in this lever to engage the wharl a<4> on the spindle and stop it, when the sleeve l is moved away from, and the lever l<5> consequently drawn towards, the spindle. The bracket l<9> carrying the pivot l<3> is controlled by a stopmotion rod m, which, when depressed, moves the sleeve l away from the wharl a<4>. The rod m is pivoted on a lever n<2>, Fig. 8, carried by a bracket on the frame a<3>. The lever n<2> is supported by the engagement of an extension of the pivot pin n<3> with a notch o<2> in a lever o pivoted at o<1>. A lever p pivoted at p<1> carries a yarn guide p<2> and a dropper q with a projection q<2> moving against the arm o<4> of the lever o and adapted when the yarn breaks to come into contact with a rocker r<1>. The lever o is then moved about its pivot and the notch o<2> withdrawn from beneath the pin n<3>, allowing the lever n<2> and rod m to fall. When the cop is fully wound, the disk i<1> is arranged to come into contact with an adjustable device s at the end of the lever o. According to Provisional Specification 21,219/14, the vertical movements of the spindles may be obtained by the use of a heart cam around which a chain is passed. attached at one end to a lever controlled by a second cam, and at the other end to an arm on a lifter shaft, such shaft carrying levers on which the spindles rest. The cams are so adjusted as to give a steady movement to the spindles.

Abstract: 7361. Bancroft, J. S., and Indahl, M. C. Oct. 6, 1914, [Convention date]. Single-type composing and casting machines, convertible for casting leads etc.; moulds.-Apparatus for casting elements for use in printing formes, such as leads and rules, is adapted to be applied to type composing and casting machines such as are described in Specification 8633/99. The mould consists of side blocks 5, 6, Fig. 11, between which works a rather wide mould blade 3, Fig. 10, the opposite side of the mould being closed by a sliding cross-block 17. The top of the mould is formed by a vertically adjustable filler-blade 12. The mould blade may be equal in thickness to the thinnest lead to be cast, the remainder of this wall of the mould being formed, when thicker leads are cast, by a filler-block 4. The thickness of the mould is determined by a point-block 7 interposed between the side block 5 and the end plate 8 of the mould. The side block 6 is formed with apertures near its ends to permit it to yield slightly, and is clamped, during casting, by a pressure-screw 11. The cross-block 17 has, at its lower edge, blocks 18, Fig. 7, forming between them a jet-passage 19 in which works a jet-ejector operated by a fixed cam 20, Fig. 10. A fixed projection is provided for knocking off the jet. The lead is ejected into an opening 23 in the cross-block, in which it is retained by spring fingers 25 bearing against ribs. The cross-block is clamped against the side blocks during casting by a pressure-screw 26. The leads are discharged by the usual pusher or ejector into a channel from which they are stacked in a box. The pressure-screws 11, 26 are operated by crankarms from the usual centring-pin actuating lever of the machine. Means is provided for giving an increased movement to the mould blade, which is operated, as heretofore, by a rod 122, Fig. 1, from a bell-crank lever 128. On the lever 128 is pivoted a second lever 130, one end of which engages the rod 122, the other end having a guideway 132 in which rests one end of a short reversible lever 133. The lever 133 is pivoted on an extension of the lever 128, and its other end works between fixed adjustable stops 135. The lever 130 has a large opening for the pivot of the lever 128, to permit of relative movement. By renewal of the lever 133, the arms of which are of different lengths, different extents of movement can be imparted to the mould blade.

Patent GB-191515555-A (GB)
Title: Improvements in and relating to Electric Vacuum Devices.
IPC: H04B1/16
Filed: 1915-11-04
Abstract: 15,555. British Thomson-Houston Co., [General Electric Co.]. Nov. 4. Vacuum tubes.-An electron-emitting cathode, an anode, and a third electrode are arranged so that, for a certain range of electric pressure, the current between the cathode and third electrode varies oppositely to the pressure. Such a " negative resistance " tube can be used for amplifying pressure-variations, for example, in wireless receiving systems. The heated filament cathode 2, Fig. 1, anode 4, and third electrode 6 are designed so that electrons from the cathode can easily reach the third electrode, secondary electrons from which can reach the anode. As shown, the anode is of grid form, and the third electrode is a hollow cylinder surrounding the others. Exhaustion is preferably so complete that there is no indication of gas ionization during working. A constant electric pressure is applied to the anode and cathode. As a potential increasing from that of the cathode to that of the anode is imparted to the third electrode of such a tube, the current through the third electrode first rises from zero, then diminishes in consequence of the increasing velocity of electron bombardment and the resulting emission of secondary electrons, and finally increases again in consequence of the diminution of attraction of secondary electrons by the anode. A constant potential is applied to the third electrode so that it works on the intermediate diminishing part of the pressure-current curve. A battery may be connected to the cathode and third electrode of the tube through a resistance. Pressure variations superimposed on this circuit are magnified at the terminals of the resistance, the amplification being greater the more nearly the resistance approaches in magnitude the apparent negative resistance of the tube. Thetube is shown utilized in wireless receiving-apparatus in Fig. 3. The plate electrode 18 of a primary audion 16 is supplied with current by a section 20 of a battery 21 through a resistance 22, and is also connected to the third electrode 28 of the negative resistance tube, which is thus in shunt to the audion 16. Increase of current through the audion causes diminution of pressure on the electrodes 18, 28, and consequent increase of current through the negative resistance. The diminution of pressure is therefore greater than that due to the audion current only.. A secondary audion 23 has its grid electrode connected to the plate 18 of the primary audion, and its plate electrode supplied with current through a telephone by a second section 25 of the battery 21. The whole battery pressure is imposed on the grid anode 27 of the negative resistance tube. Specifications 21,629/00 [Class 40, Electric telegraphs &c.] and 15/788/ 14 are referred to.
