Title: Improvements in Interlocking Levers for Railway and other purposes.
IPC: B61L19/02
Filed: 1916-03-28
Abstract: 104,934. Tyer & Co., and Dunkerton, J. G. March 28, 1916. Hand-levers, interlocking.-A mechanism which ensures that one lever cannot be pulled until a second one has been operated either over or back to its full extent, and that the first lever is selflocked on replacement until the second is reversed, comprises bridle bars J, P so connected that one is free while the other is locked. These bars are connected, in the apparatus shown in Fig. 1, by a swinging lever Z pivoted on a third bridle bar K. The fouling-bar lever is connected to two plungers A, D, and the signal lever to two plungers U, U'. Normally, the plunger U is locked by a pawl S. When the plungers A, D are pulled forward, the bridle bar P is moved by means of a projection C and a block 0, and rocks the lever Z about its joint with the bar J, which is locked by a rib E entering a slot F. The bar K is thus moved so as to cause a block Q to rock the pawl S clear of teeth V. The plungers U, U<1> are thus free to be drawn forward, and at the end of the stroke, a bevel V<3> moves a block R and the bar K towards the left, and the pawl S is free to lock the plunger U on replacement of the lever to normal. On the reverse stroke of the fouling-bar lever, the bar P is held by a rib L, and the bar J is pushed to the right, thereby moving the bar K so as to set the pawl S clear of the plunger U. As an alternative to the swinging beam Z, the motion of one bar may be transmitted to the other by means of sliding blocks 4, 5 and a roller 1, Fig. 4. In apparatus with catch-handle locking, a tappet locked by a pawl rigid with the pawl S may be connected to the catch handle so as to lock it when the pawl S is in locking position.

Patent GB-621955-A (GB)
Title: Apparatus for measuring the distortion of start-stop telegraphic signals
IPC: H04L12/26
Filed: 1946-02-14
Abstract: 621,955. Type-printing telegraphy. PELLE, P. Feb. 14, 1946, No. 4726. Convention date, July 5, 1944. [Class 40 (iii)] A start-stop telegraph distortion - measuring apparatus comprises a cathode-ray tube, the beam of which is suppressed except at-the characteristic instants of the received signals, the scanning path being a series of parallel lines with a rapid fly-back from the end of one line to the beginning of the next, the characteristic instants of a perfect signal appearing as illuminated spots at the middle of each scanning line, the line joining these spots passing through the initial position of the beam and being perpendicular to one scanning direction. An incoming start signal applies a battery B to the coils E1, S1 of two relays I and II in series, moving their armatures a1, all, on to their operating contacts t1, t11, to release an oscillator comprising condenser C1 and thyratron H1 and a second oscillator C2, H2. The output of oscillator C1, H1 is of saw-tooth form and a period equal to that of a signal element, and is applied to the X plates of a cathode-ray tube C. The oscillator C2, H2, has a similar output, whose period is that of a charactersignal and is applied to the Y plates. The electron beam therefore traces the path o, a, b, c, ... g, h, o (Fig. 3a). At each swing of the armature a at the transmitter the battery B is momentarily removed from a resistor R12 and the cessation of current therethrough applies a positive pulse via a condenser C3 to the lightmodulating grid W of the cathode-ray tube C. Thus a luminous spot P, Fig. 3a, is produced on the screen at the characteristic instants of the received signals. If the signals are undistorted the spots P will appear on a vertical centre line and a graduated scale is added to enable percentage distortion to be read directly by the deviation of the spots P from this centre line. When the oscillator C2, H2 has completed one cycle, the condenser C2 discharges through the thyratron H2 and coils S2, F2 of relays I and II in series, returning armatures a1, a11 to their inoperative position and immobilizing the oscillators. The oscillators stop at the centre of the received stop signal since the oscillator C2, H2 is locked to the oscillator C1, H1 by the impulses applied to the grid of the former via a transformer T1.

Title: Apparatus for continuous casting

Abstract: 1387992 Continuous casting ALCAN RESEARCH & DEVELOPMENT Ltd 15 Feb 1972 [16 Feb 1971 3 Feb 1972] 4780/71 and 5187/72 Heading B3F Metal, such as Al or Zn, is cast as a continuous strip between a pair of moving belts 15, Fig. 1, forming a mould space where they each travel in a path (possibly vertical or inclined instead of horizontal as shown) defined by a plurality of spaced supports, e.g. bars 36, Fig. 2, or rotatable elements, coolant being applied to the reverse face of each belt 15 at the mould region, e.g. through jet orifices 38 in a casing 26, Figs. 1, 4, and a fluid pressure difference, independent of the metal, being established on the opposite faces of at least one of the belts 15 for holding the belt against the supports. The spacing between adjacent belt supports, e.g. bars 36, is less than 50 times the thickness (0À020-0À060 inches) of a belt 15, so that the fluid pressure difference constrains the belt against buckling under thermal stress. The pressure difference results because of low pressure created in the casing 26 by a suction pump connected to an outlet conduit 29, Fig. 1, to extract coolant water from an outer plenum chamber 33, Fig. 4. Due to the low pressure, water entering an inner plenum chamber 32 is drawn as jets through the orifices 38 formed in a relatively thick wall 34 of the chamber. From shallow channels 37, between the wall 34, bars 36 and belt 15, the water is drawn into deeper channels 39, extending obliquely of the channels 37, and passes down tubes 40 to the outlet chamber 33.  A launder 23, shown retracted in Fig. 1, bears resilient side guides (51) for directing two edge dams 22 carried by one belt 15 (the upper, as shown) and in the form of asbestos-clothcovered white metal or rubber. To determine the taper of the mould space to relate to casting shrinkage, the upper casing 26 (as shown) is pivoted in trunnion bearings 43 at the mould inlet by a lever 44 operable between stops 47, 48. The operating cylinder 45 also provides resilient loading. The inlet belt-spacing is finely controlled by adjustment screws acting on tie bars 41.

Abstract: 1464847 Welding by pressure INST ELEKTROSVARKI IM EO PATONA AKAD NAUK UKRAIN SSR 6 Feb 1975 5194/75 Heading B3R [Also in Division G3] In a method of flash butt welding, workpieces are moved relatively towards each other with a continuous motion on which there is superimposed a reciprocating motion. The length of welding current pulses caused by the reciprocating movement is measured and compared with a predetermined value, any difference being used to adjust the relative movement imparted to the workpieces. As shown in Fig. 1, workpieces 1, 2 are held respectively in a fixed clamp 3 and a clamp 4 which can be moved by an hydraulic actuator 20. Welding current supplied over a mains transformer 5 is measured by a current transformer 6 connected through a pulse shaper 7 to one input of a comparator 15 which also receives an input representing a desired welding pulse length from an A.C. or pulse generator 17. The error signal from the comparator 15 may be supplied either to the continuous drive mechanism 18 or to the reciprocating drive mechanism 19, both of which are connected to the actuator 20. In the former case, the continuous drive speed is adjusted, while in the latter case the amplitude of the reciprocating motion is varied. In a modification, Fig. 5 (not shown), the pulse shaper 7 is connected to a relay switching device controlled by integrating and differentiating circuitry so as to produce a unidirectional voltage which can be compared with a constant voltage reference signal in order to produce a control signal for the drive mechanisms.
