IPC: H01B17/28
Filed: 1958-02-11
Abstract: 877,055. Insulators, cable terminations; cable joints; SIEMENS - SCHUCKERTWERKE A.G. Feb. 11, 1958 [Feb. 13, 1957], No. 4486/58. Drawings to Specification. Classes 36 and 38 (1). Insulating members for use in high-voltage cable straight joints, sealing ends or as bushing insulators consist of thermosetting or coldsetting cast synthetic resin having embedded therein a conductive or weakly conductive insert for potential control the insert having air or gas-filled cavities rendering it compressible and/or expansible. The resin may be polyester or epoxy based and the insert may be conducting or weakly-conducting foam rubber, or may be weakly conducting paper, textile, or other fibrous material, which may be a covering on a rigid, e.g. metal, body, it being essential that the resin does not fill up the air cavities when the insert is embedded. A metal stress ring may be thus covered and embedded in resin to form part of a straight joint or. sealing end, constructions of these being described (Figs. 1 and 2, not shown). Channels may be provided in the resin body so that when the member is used with oil-filled apparatus the oil may at least partially impregnate the insert. In a bushing insulator through which a bare conductor passes, the conductor may also be provided with a covering of the same or a similar conductive material as the insert (Fig. 3, not shown).

Title: A means to prevent more than one train being on a section of single line railway at one time
IPC: B61L23/12
Filed: 1921-02-11
Abstract: 176,237. Hall, H. W. B. Feb. 11, 1921. Signalling-instruments; combined electrical and mechanical systems, non-automatic.-At each end of a section of single line a switch for a stop siding is interlocked with a signal instrument to prevent a train from entering the section until the right of way is given. The instrument has two discs d, e, the former, d, operated by hand and the latter, e, operated by the instrument at the far end of the section. The sid'e switches and their signals cannot be operated until both parts of both instruments have been put in the position allowing a train to proceed in one direction. When a train has left the section it runs over a ramp and thereby sets both instruments at the " line clear " position. The connections between the ramps and instruments may be electric, mechanical, or pneumatic. The discs d, e have indicators W, X, Y, Z which appear behind a window 11, and have locking-notches d<4>, d<5>, e<4>, e<5> to engage levers h', h<2>. The locking-bar g has a head g<1> working in slots d<1>, e', which have expanded ends as shown in Figs. 6 and 7. The bar g is attached to a slide engaged by tappets connected with the guard signal levers, so that closing the switch causes the bar g to drop, and the switch cannot be closed' unless the discs d, e are in a position to permit the bar to fall. Solenoids or cylinders N, O under the influence of the distant instrument and the ramps respectively control the repeater disc e and the release gear h<1>, h<2>. Before despatching a train the signalman moves the handle k to the position k<1>, Fig. 2. This rotates the disc d to bring the indicator Y to the window and brings the end d<2> of the slot d<1> opposite the head g' of the bar g. The solenoid or cylinder N of the instrument at the far end then operates the disc e of that instrument to bring the indicator X to the window and to ring a bell. The second signalman, if he is ready to receive the train, operates the arm of his instrument to rotate its disc d and energize the solenoid N of the first instrument. This pulls down its core with the slotted plate f attached and operates the disc e to bring the indicator W to the window, to bring the end e<2> of the slot e<1> opposite the head g<1>, and to cause the contact e
 to slide past the contact h' thereby ringing a bell. The levers h<1>, h<2> lock the discs in position and the slots allow the bar g to move down to release the lock on the signal levers. After the train has entered the section, the first signals are returned to their original positions. This returns the bar g, the slotted plate f and disc e to their normal positions and prevents another train from being signalled in the same direction. When the train reaches the far end of the section it passes over a ramp and causes the solenoid or cylinder O to depress the lever h<8> to operate the detent h<3> and release the lever h<1> thereby allowing a spring to return the disc d to zero.

Abstract: 397,173. Bunkers for coaling locomotives. MITCHELL, F. G., Albyns, near Romford, Essex. Feb. 18, 1932, No. 4871. [Classes 78 (iii) and 78 (iv).] In an overhead stationary bunker suitable for coaling locomotives, one or more sides are formed with horizontal openings arranged at successively higher levels and from each of which extends, in an inward and downward direction within the bunker, a shoot having lower and upper walls or plates and through which coal can be discharged and allowed to fall into the bunker as the level of coal therein, in relation to the shoot, permits, the upper wall of each shoot being so arranged that it will sustain coal when the level thereof in the bunker extends above its lower inner edge and will prevent, in conjunction with the lower plate, the escape of coal by gravity through the inlet of the shoot. As shown, one side of the bunker 1 is provided with inclined plates 3 forming a series of superposed shoots, and two or more such series may be arranged side-byside, the interior of the bunker being then divided transversely by one or more vertical partitions. Coal is discharged from a wagon 7 into a container 6 by means of a side discharge tippler, for example of the type described in Specification 242,716, [Class 78 (iv), Loading &c.], or, in a modification, by means of a rotary tippler mounted above the container. The container 6 is mounted in a hoisting frame 18 provided with rollers 19 adapted to run in guideways 5, and may thus be raised to the height required by means of ropes 20 and hoisting-drums 22. The container 6 discharges, under the control of a flap valve operated by a lever 11, into one or more shoots 13, the lower ends 13a, Fig. 3, of which are each provided with a valve 15 provided with an angular extension 17, which, when the valve is in open position, forms a continuation of the lower bunker shoot plate 3. The valve 15 may be actuated by worm gear 16. Specification 389,578 also is referred to.
