Title: Improvements in Means for Operating Signalling Indicators for Collieries and the like Works.
Inventor: JOBLING JOHN WILLIAM
IPC: B66B19/06
Filed: 1916-10-06
Abstract: 110,922. Jobling, J. W. Oct. 6, 1916. Mechanical telegraphs; mine and colliery signals. -In signalling apparatus for colliery use, to allow for stretching of the signalling wire, arrangement is made whereby a greater movement is given to the wire than is necessary to operate the signal indicator, a lost motion device being introduced to prevent damage to the indicator. The arranement also admits of the use of the signalling wire for " knocking back." As shown in Fig. 1, the signalling wire b is attached to a floating lever g provided with a head h resting on a support j. The signalling impulses are given by either of two cranks n, n<1> operated by corresponding handles p, p' and connected through links k, k<1> with the lever. The connexion between the cranks and links is of pin-and-slot type so that, when either link is pulled, the other can slide freely. During the first part of the pull, the lever g pivots about its head h until the movement of the wire b is arrested, as by the operating-arm d of the indicator engaging a stop. Further movement of the links pivots the lever g about the point f, the head h being raised. The engineman can use the head h for knocking back by pulling on the wire b. A second indicator is shown operated by a wire b<1> attached at f<1>, a spring s being interposed in the wire to prevent damage to the indicator. Ratchetwheels r, r<1> may be added to ensure complete rotation of the operating-handles. In a modification, the lever g is pivoted to a sliding member operated along guides by a crank and connecting-link. In another form, the head end of the lever is guided and supported by linkwork. As shown in Fig. 3, movement of the links k, k<1> is communicated to the wire b through a spring 4 and slotted member 7. In this case, the pivoted lever h is only used for " knocking back," the required lost motion being provided for by the spring. In another form, Fig. 7, the wire b passes round pulleys 9, 10 and is attached to a weight 12. The pulley 9 is carried by the crank n, so that, on rotating the handle p, the wire b is first pulled until arrested, further movement raising the weight 12. The weight 12 may be used forknocking back. A modified pulley arrangement is described which can be operated by either of two independent handles.

Title: Improvements in control systems for glow discharge vessels
IPC: H01J37/32
Filed: 1957-05-03
Abstract: 841,485. Supply systems for discharge vessels. DORTMUND-HORDER HUTTENUNION A.G. May 3, 1957 [May 4, 1956], No. 14223/57. Addition to 807,345. Class 38 (4). In a circuit for supplying a glow discharge vessel, an element is arranged to shunt the vessel on an arc being formed, thereby reducing the voltage across the vessel causing the arc to be extinguished. The vessel 73-75 is supplied from a D.C. source 82 through resistors 83, 84. The increased volt drop across resistor 83 due to arc current is applied through a time delay and biasing network 104-108 to a thyratron grid 109 causing the thyratron to fire and discharge a capacitor 101 through auxiliary electrode 88 of an ignitron 86-88 which, on firing, shunts vessel 73-75, thus extinguishing the arc. A time delay network 114-117, connected across an anode resistor 90 operates a relay 91-93, disconnecting the ignition and re-establishing normal circuit conditions. Other arrangements of firing discharge tubes are described in the Specification, and the passive tune delay networks may be replaced by electronic delay circuits. Specification 806,637 is referred to.

[Also in Group XXXV] In a method of making a slip ring assembly, a single tube is slid over a tubular or rod-like support member, the tube is cut into spaced lengths, each of which lengths forms a separate slip ring. In its final position, a conductor is fed into each of one or more passages or channels provided by the support member parallel to the assembly and each wire is connected to a different ring. An epoxy-resin coating 2 is moulded around a rod 1 and is slotted to form spaced splines 3. A brass tube with internal truncated splines 5 is pressed over the resincoated rod 1, the complementary sets of splines forming an interference fit. The periphery of the tube is then machined to form spaced sliprings 4, the spacing grooves being cut to slightly penetrate the resin coating of the rod 1. Wires 7 are centrally located in channels 6 formed by the mating of the splines, each wire being soldered to a different ring. A further epoxy resin coating 8 moulded round the whole assembly is subsequently machined down to expose the rings which are then first nickelplated followed by a rhodium plating. One end of the assembly is fixed into the bore of a ballbearing pivot and held by an adhesive. In a modification the rod 1 may be replaced by a tube. In another modification one ring may be partially severed by a radial hole drilled prior to separating the rings, to form a switch.
